1889. Electric Light - General (D-89-33)
This folder contains correspondence and other documents relating to electric lighting and power. Included are letters pertaining to the incandescent lamp, the alternating current controversy, and electrocution experiments conducted by Harold P. Brown, a New York electrical engineer. There are also documents concerning lamp tests conducted by the Chicago, Burlington & Quincy Railroad and by the Niagara River Hydraulic Tunnel Co., which was established to develop a hydroelectric power system in Buffalo, N.Y. Edison advised the company about the construction of central stations and about a direct-current distribution system. A series of lengthy memoranda written by Edison on this subject can be found near the end of the folder. There is also a satiric pamphlet relating to the patent litigation of the Edison Electric Light Co. Among the correspondents are H. Ward Leonard, an electrical engineer involved in lamp tests, and Edward D. Adams, president of the Cataract Construction Co. and a promoter of the Niagara Falls project.
Approximately 80 percent of the documents have been filmed. The following categories of documents have not been filmed: routine requests for information about electric lighting, electrocution, and Edison’s fiber search; letters of transmittal; other routine business correspondence; duplicate copies of selected documents.

[FROM FRANK MCGOWAN?]
Mr. Brown's circular regarding the danger of alternating currents, which includes a copy of the Medico-Legal Society's report has been sent to the Mayors, members of city Governments, Insurance men and principle business men in every city and town of over 5,000 inhabitants in the United States. --
As a result, every mail brings him a pile of letters from all over the country asking for all sorts of information and ad¬ vice. These enquiries are followed up and in two or three dif¬ ferent towns he has been requested by the Mayor to visit them and make an examination of the existing plants, take electrical mea¬ surements with a view to determining leakage &c. and generally ad¬ vise them, in regard to the danger &c. He will of course accept these invitations, and he has all the instruments necessary ex-— cepting a Photometer to' me asure<a*& lights. ' He tel ls mo that you have- such an instrument and wants to know if you could spare it-- for a short time. I know that you will recognize the importance of this and if you cannot spare the apparatus which you have, can you advise iae where to go to get one?

ifr. Upton has given me the batch of lamps which you sent out, and 1 shall endeavor to get them entered in the test at the C. B. & a. Mr. Upton suggests operating them at about’ 320 candles per electrical horse power. I will endeavor to place them in this way •unless you have some other desire. Mr. Pierce, the expert who is con¬ ducting the test, is thinking of making microscopical examination of the filaments of the various lamps, new and old. I told him- X thought a good deal of work had been done in this line, hut that I would find out from you in regard to the nutter and learn whether TO weul<£ he likely to lead to interesting Results. V/ill you kindly let- me know what has been done in this line, and what the p^eVis of: learning .anything thereby?
Yours very truly, .

th&t I have awulf witnessed the reduction in accordance woth one' oi the patents examined by Mr. Kennelly of a potential of 1000
volts down to less than 50 volts, and the lighting of incandescent lamps by the induced c undent which apparently was as steady as the usual alternating currents used for lighting.
Mr. Kennelly1^ assertion that 1, he ihvention has no basis in theory of practice served to demonstrate the complete novelty of the invention.
Orange, N. J. .!
My Dear Mr • Edison, J have frequent occasion to test arc lights in behalf of city authorities who hayfe contracted for them as Itghts of 2,000 candle power j and -j these are not always satisfied wtth measurements of the f volts and amperes of the curre?it. As l always leave the. mayor and coundl pledged to a& ordinance prohibiting the i alternating current at higher E. M . F. than *300 volts , /' trust you will pardon my addressing you concerning the
i
practicability of a photometer for getting merely approx¬ imate measurements from the lamps as they appear in ser¬ vice. The only feature of novelty is that a pane of col¬ ored glass is setjfaii attgle midway between the angles Of Itght rays received from both sources; parallel with this \ is a sheet of ground glass, one half of Which is illumina¬ ted from each source . As the Itghts are thert of the same color, the distance of the standard light can be varied until the line of demarcation between the halves is lost.
By setting the bottom “c d« level and arranging the aper¬ tures so that angle "bfaXKmust be of soy, 45 degrees {.for uiong arc« lamps) in order that the Itght from a shall strike the screen "fj1 the length of "hf may of course be
determined by measuring t7ie base of the triangle, I do not know whether the color £z tithe glass "e'will have unva¬
rying effect Upon the Hgfyt from; t7tm:ity^p^^r^S^6ur» ces and , if so, what the variation would be. It will
add greatly to my obligations to you if you can see that
. . (vi it i
i am set right tn the mattert and ^indicate some candle
or portable lamp to be used as a standard. ■

My Dear Mr. Edison ,
Early last month I visited Scranton as an expert for the city to determine whether the arc lights were up to contract requirements and to formulate means of making their many overhead wires safe. I inclose a copy of my report and have marked my recommendations. I found that the Brush local company were preparing to put in an alter¬ nating current system and therefore have laid great stress upon the necessity of adopting an ordinance pro¬ hibiting this current at a higher pressure than >3oo voitst Of course they have raised a great outcry and -^zre attack - ing me, endeavoring to discredit my ab i li’t^H^^^nc l osd letter from Mayor Ripple will explain its^^^^^you can. conscientiously send me a line or two which I can show to Mayor Ripple, I shd, l be able to add Scranton to the list of cities whicbt have shut out the high tension alterna¬ ting current which is unsuiied for commercial lighting.
Ihe local Edison manager , the telephone and telgraph supts., and the Sprague R.R. people have approved my rec¬ ommendations, but the Brush people have set their hearts upon getting in the executioner's current.

As the Westinghouse Electric Co. are making strenuous efforts to introduce their apparatus, and are urging in its favor its 1 'economy1 1 as well as its •' 'safety, * 1 and &s I am frequently consulted on the sub¬ ject, I felt authorized to address to Mr. Westinghouse, on the 4th of April, a registered letter, a copy of which I enclose, giving him a fair . opportunity to have his remarkable claims demonstrated at my expense.
The official receipt for the letter has long since reached me, but there has been no reply. You will remember that Mr. Westinghouse and his experts pronounced this current "safe11 and “harmless,” and that they have violenty attacked the writer for maintaining and proving that it was dangerous. As a result of my work, the New York State author¬ ities, after a long and thorough investigation, have purchased foj- electrical execution three Westinghouse alternating current dynamos, built for electric lighting. Having thus proved my point as far as the danger of the apparatus is concerned, I am anxious to have its commer¬ cial value definitely settled by the proposed test. I would therefore be glad to receive from you any suggestions concerning methods, or any results of your experience with the alternating current that you may care to place at my disposal. In return I shall take pleasure in sending you copy of report of the tests when completed.

Dear Sir: The public admission made at Harailton by Mr. Stlu_
Z W y°Ur;hleCtriCian' that he * — of at least three men killed by the Westinghouse alternating current which you have pronounced safe and the adoption of the same current by the State of New York for electrical executions, are sufficient reasons for your failure to accept

You did not dare to risk your life to prove the sincerity of your statements concerning the safety of the Westinghouse alternating current. Will you now dare to risk your money to substantiate your claims as to the efficiency of the Westinghouse alternating current ■ system ?
If so, I hereby give you an opportunity to sell another electric- * Statl°n (With 650 lan)Ps of 16-candla Power each), and obtain an extensive advertisement at my expense.

To substantiate this remarkable claim, I challenge you to send a complete 650-light Westinghouse alternating-current plant with not less than thirty converters, to the. Electrical Testing Bureau of the Johns Hopkins University, to be there installed by your own experts and left

there was a "condenser action" between the conductors of ajaJ&.l- ternating current system and the moisiMre or conductive cover¬ ing on the outside of the insulation of same, that would con¬ stantly tend to discharge to the ground when possible and might draw the current in its path; that it would also result in aJir_ loss of energy in an extended system. Dr. Duncan did not at first agree vvith me but he has come around to my position and the two deaths recorded in inclosed dipping are frightful ver¬ ifications of my theory. I wish in the Baltimore test to es¬ tablish at least approximately, what this loss of energy will be and would be glad to have you suggest the best method of dor ing so. I have known of a series of five 50 volt lamps being run up to c.p. when placed between one terminal of a Y/. dynamo and the lead covering of an insulated cable attached to the other terminal; also of two men being unable to release them¬ selves after taking hold of two lead covered cables (2,500 volt alt. current) until dynamo was stopped Sincerely Yours

V/m. B. Rankino, Esq.,
D*ar sir:-
I respectfully submit to you an estimate specifi¬ cation and a cross-section for the main tunnel, also approximate estimates for one hundred feet of canal cross tunnels &c . with assumed plans for same .
I have given more att aition to the tunnel specification than anything else, and think you will find that they cover any and every thing that is likely to happen in constructing the tunnel. Upon consideration of the trouble which might be caused, owing to a lack of items and prices in the specifications, I have made them so as to include masonry and timbering. Of course in the rock at Niagara it ib highly improbable that any place in the tunnel will be found which will require permanent supports, but if such should be the case the specifications will cover everything, and as I have given the Engineer the whole power to order such timber and masonry, as he may deem necessary to furnish all plans and t o di- roct the construction of the same, should any bed ground be found the Company will have the entire control.
The prices I have given in the estimate for the tunnel 1 consider after careful investigation to be very fair, and have no doubt that. the contract could be let for much less .
Tho area of the cross- section for the tunnel corresponds practically with tho area of a circle twenty-four feet in diameter and I consider it. to have many advantages over a circular section m regard to the construction, and flail of water.
The estimates and plans for the canal cross tunnels &o. are simply approximations, and nothing definite can be arrived at until the Company has in its possession, first, a complete ground Plan showing the land, the bott an of the river to a depth of nine feet below the surface of the water, the location of the main tun¬ nel with reference to the original surface, and the boundaries of the land taken by the Company, also, some idea of how far the rock lies below the surface of the ground and water; and, second, a definite plan of the manner in which the Company wish the power developed and distributed, the number of wheel pits and the depth fdr the wheels.
I would say further that it is with groat hesitation that I make any estimates or plans for the Canal, cross tunnels and work connected therewith, owing to a lack of the information I have stated above. The canal shown on the plan, is sufficiently large to adwit of vessels and canal boats, and to furnish the ten thousand horse power required under ordinary circumstances, and I
have planned the same as to dimensions and strength of sides si to admit of shipping facilities.
I am,
Very truly yours ,

New York, 16th. October, 1889.
Orange,
Dear Mr. Edison?-
Jersey. ’ ' _ ^
|>A <*-**"'
end you by this mail copy of a map of the City of
Buffal^that may be of use in connection with your study of the i Falls project. ^
I learn from the local agent of the Hartford Boiler In¬ surance Company in Buffalo that they estimate the total horse power used daily in that city as between 60,000 and 75,000. Jfearly accurate figures can be procured in about a week’s time and at some expense if the estimated statement is not sufficient. Coming from this authority and based upon the business that they do and ythat which they would like to do, I think we may assume it is fair- r correct .
In the town of Tonawanda, I am reliably informed, that
3,000 horse power is used by the wood-working establishments alone, 250 for the lighting of the town and not less than 35,000 up to a maximum of 50,000 for all the manufacturing purposes. The gen¬ tlemen in control of the wood-working establishments are those who have offered to take power for themselves and light and power for their electric Company.
The following distances are furnished me by those who know, as those which would be available as av.rdute .^or rright of
Thomas A. Edison, 2:
way between Niagara Palls and Buffalo:
Tunnel lands at Niagara Palls to center of the town of
Tonawanda, 9 l-s.miiles
Tunnel lands to northern city limits of Buffalo 13 2-3 miles Tunnel lands to City Hall, Buffalo, 19 1-6 miles.
The City Hall is located one mile beyond the manufacturing center of the City.
I telegraphed you a few days since that the engineers, Messrs Evershed and Porter, are within call and I can arrange for them to meet you at any time and place you may select, for such ex¬ planations as you may wish from them as to the details of their proj ect.
In considering this business, I do not know that I suf¬ ficiently expressed my idea upon it in our brief interview the other day, and therefore recur to it now. I look upon the enter¬ prise first as a project to furnish power by electrical means in the iirmediate vicinity of the town of Niagara Palls. A compar¬ atively small amount of light would also be consumed there. That if the project upon this basis will return a fair rate of interest upon the capital invested, we can safely engage in the business, trusting to development under good management for the larger re¬ sults to be expected. As one of the means of obtaining large
profits, we.. look, ’ first: to the supply of light to Tonawanda and Buffalo; second: to the supply of power to those places.
Thomas A. Edison, 3!
Professor Rowland writes me that he has, in the prepara¬ tion of his report, written to each of the various electric light companies for special information upon the subject. If there is any information that I can gather for you through my assistants^ shall be happy to do so, and if you think best at any time I will make an appointment v/ith you some evening for further discussion of
Sincerely yours.

My D$ar Mr. Edison, As requested I send you herewith a list of the deaths from electric lighting which have been brought to my notice through newspapers, correspondence etc. As such accidents in the past have been hushed up I feel that my list represents little more than haLf the total number. I have enough, however, to show that the advent of the alternating curront during the past two years has greatly increased the death rate. The total deaths in 1886 were but 10; in 1887, 19; in 1888, 42 and the rate so far this year will shove a corresponding increase. I have se¬ cured a list of all the building lighted with the alternating cur¬ rent apparatus in this city and will be able^as soon as the sta¬ tions start up after the injunction matter is decided, to indicate just where interesting tests for leakage can be made on a wet

Tho facts are as follows
. We“ba vb several circuits of over twenty five (25) miles in
length and at times in fact, run over frequently. We have coupl- -^ed,Ntwo:;{2) circuits together, thus carrying the current through , fifty (50) to sixty (30 ) miles of wire. None of this wire was ^dVe^number six (3) in size and much of it was number eight (8). fe:JlB* nin eleotrio m^ors, arc lights and incandescent lights all;on|ebe same circuit and do so regularly. As to loss of lights of long lines, we have many long circuits and on some of the long¬ est of them we frequently run full sixty five (35) two thousand (2000 ) candle power lights. That is the full quota of lanps for the machine.
This is the substance of what Hr. Leggett, President of the Hrush Electric Light Oo. said to Mr. Ely recently and which is doubtless the foundation of the inquiry, aB Mr. Leggett informs me. Very truly yours,

Dear Sir:-
Niagara Falls, JJ. Y.
October 24, 1880.
Your letter of 22d received and the data desired will be irrmediately procured and forwarded to Mr. Adams.
It may be of interest to state that at an interview to¬ day in Buffalo with Mr. Adams, Vice Prest. of the Brush Electric Go., he gave me the following info relation
1st. The present use of power by the several Electric Co's, is as follows
BruBh Co., 900 to 1000 h.p.
Thomson-Houston Co., 500 "
United States Co., 250 "
2d. He estimates SriOOO to 50,000 h.p. as the total in gener- eral use in the City of Buffalo.
!i. He states that they have one circuit of 20 miles upon which a 30 arc lamp dynamo supplies 00 full limits of 2000 c.p. each. This line has been in successful op¬ eration about two years.
> 4th- He fixes the loss of their motors for power at 15j5 .
They deliver 85ji of net power from their stations and collect pay for it.
2
He states that the growth of their business is restricted owing to insufficient aoconmodations at their stations.
They supply lanps and power off the same wire, but re- coirmends separate lines, within the city or town, to avoid annoyance to both classes of consumers as they frequently demand both light and power in excess of the line capacity.
Ab to cost of power to the Brush Co. in answer to the question he gave the cost of coal only, stating that to obtain the cost of power we must; figure the usual ex¬ pense of handling, attendance of.iergine, stokers wages &o. This, using the lowest estimates and under the very best conditions he gave, ''.figures out $80.00 per h.p. per a mum.
Remark, that he stated that their largest and best engine (working under 300 h.p.) bnly gave theBe results
The enclosed clipping from to-day’s Buffalo Courier shows trial balance of the Brush Co. which Mr. Adana stated was furnished from their books.
Please observe that their stock of One Million dol¬ lars is one half water; .80 that the return of 3 % he
3
figures out Tor- the public equals really 13$ upon actual capital.
Mr. Adams further stated that he considered the electri¬ cal business as good for 8 to 10$ safe earnings upon the investment which would seem to be in line with the showing of his Company.
Very Re spy..

Niagara Falls, H. Y. October 27,1380.
jj My dear Mr. Rankine,
Yours of the ' 2ot.li just, received.
A few days since a gentleman came here from Toronto fresh from a conference with Canadian parties who had asked him to take hold of the Canada schema and take It to England to be capitalized. He stated to me that the terms which the Canadian authorities exacted for permission to use their reservation lands and for access to the run and use of its waters, were
1st: A payment of $r>0,0»0 cash, for the two first
jj years of occupancy and use, i.e. 02!i,onn per annum rental, jj Thereafter an annual rental of $30, 000 up to and indudinc 20 years, and then the Canadian authorities would fix the future charge at such sum as the worth of the plant, its | usos would warrant. Or that they would a^ree upon
jj $30,000 annual rental if satisfactory to the parties who were interested.
My informant stated that much effort was made to jj soften these terns, but without avail and that, he, person- j ally, preferred the Hiafjara Falls (Tunnel) plan and wished to secure it for London partios who would at once take hold J and build it Ac. Ac. He further stated that the authori- j ties at Washington had been asked about, duties upon the j power to be transmitted to the American side and that no j favorable decision of freedom from taxation or duties could || be obtained which was another obstacle Ac.

!' "and if 60 days' time, with control, can be given me I will |

i! Assuring him of our inability to entertain any prop
j| osition,- the interview ended.
From another source I learn that the terms of the !! Canadian government are sub start ially those given me by this i
party. j
It would seem to be unnecessary to call attention !
to the difference existing between the two regions and people separated by the Niagara Kiver. upon the American side, within 30 miles of Niagara Falls; we have 400,000 population, 15 great trunk railway lines, and with every || pound of available water power in full use and probably 30 to 75,000 hotise power made from coal in full and active j

Upon the Canadian side within 30 miles, they have a I population of less than 75,000, two lines of railway, with several thousand unused house power (water) along the Welland Canal and with a class of people 50 years behind the Ameri¬ cans in energy and ability to thrive and prosper.
That their power can be transmitted I do not doubt. That it can be of any local value for millB, factories Ac.

of ability who will carefully examine the physical features of the Canadian side of the river also welch the fact that all inlets for water to pro pal hia wheels must have thoir commencement alone the Qd':e of and within the rapids loatlinc i

MEMORANDA .
The hydraulic canal now at Niagara Palls is an open cut about 23 of ^ajriile^ in length, 7 feet_deep and 60 feet wide, cost over §300,000Aand has an average capacity of about 6,000 h.p . novf fully used. In Jan., Peby. and first half of March there is some trouble with slush or an c tor ice which reduces its average ca¬ pacity 20 to 40)< according to the severity of the winter. It should be understood that the character of ice referred to is not that which comes in solidform from the lakes .and down the river but forms in the river and open canal and frequently for several Ipurs closes all the wheels in use upon the Canal. This difficulty be¬ comes serious in proportion to the length of the open canal or con¬ duit and is lessened and removed when the water wheels are placed near the source of supply. The plans of the Tunnel Co. locate the wheel pits within 3 to 400 feet of the deep waters of the Niagara River which will insure continuous power.
It is of very great importance in planning ft>r the use of Niagara power for electric light and power purposes in Tonawanda & Buffalo that the public understand that it can be made reliable and always available. Particularly is this the case with reference to electric light the revenue from which can be made to exceed one half million of dollars annually. Were the City of Buffalo sup-

plied with light by transmission from Niagara and the power prove to be eccentric during several weeks in the winter it would give rise to difficulties of a very grave nature. The only safe. plan is, to have as little open Canal as possible, place the water wheels as near the river as practicable, with liberal connections with the Channel and the power will then be continuous and reliable. This condition of location the Tunnel plan can only supply.
The writer has had fifteen years experience as a manu¬ facturer upon the hydraulic canal here and during some of the se¬ vere winters has- suffered a loss during the months above named of from 25 to 50J* in the output of his mills. This could not have occurred under the Tunnel plan of water supply.
The construction of a 24 foot Tunnel 1$ miles permits of the discharge of water sufficient to produce 120,000 horse power. This result cannot be secured by any other plan without at least doubling the cost, and when once constructed the cost of maintain¬ ing is reduced to the minimum sinde an underground tunnel in rock once built needs no repair thereafter.
The advantages of the Tunnel project may be summarized as follows:
1st. The production of the greatest amount of power for
the sum to be expended.
[ENCLOSURE]
3
2nd. The location of the wheel pits adjacent to the river will furnish continuous power not obtainable by any other plan.
3rd. Cost of maintaining reduced to the minimum. All work to be done is in rock and. of the most durable character.
4th. As part of our plan is to absorb the Niagara Falls water supply system which will yield a revenue of 12 to $15,000 per annum, location must be had upon the river to secure pure water for domestic uses.
5th. The location of Pulp and Paper mills should be such as to permit the use of fairly clean water which should also come directly from the river. This industry will be largely rep¬ resented here. Our offers from this source exceed an annual rent¬ al of $42,000 conditioned upon location of the mills upon the riv¬ er (lands adjacent).
6th. lake and Erie Canal transportation available with¬ out added expense.

The objections to the Lewiston or Suspension Bridge scheme, are as follows:
1st. An equal sum expended on the Lewiston Co. plan will produce less than one-half the power obtained by the Tunnel !
plan.
otf- fkat't'
2nd. Requires a surface Canal of s»inw* two miles in length which is objectionable as its capacity is liable to be re¬ duced one-half at times during w inter months.
3rd. Extra cost to maintain. Passes under railroads and streets requiring bridges, excludes vessels unless the Canal is of large size adding to its cost and requiring draw- bridges, &o.
4th. Presents upon the surface a large property subject to taxation.
5th. Will not supply a power under all conditions suit¬ able for electrical transmission to Buffalo. jj
6th. Its location away from the river does not present the advantages for location of mills and factories which a front¬ age along the river gives. This has special reference to sewerage the uses of clear water for domestic and manufacturing purposes, easy access by lake and canal vessels laden with heavy freight both i raw and manufactured material. These and other special advantages j cannot be had where an inland power is located two or three miles [
[ENCLOSURE]
away from the Niagara River with which it is only connected by a slender Canal . .
7th. Finally it is not understood that this c omp sn-y have acquired any lands upon which to locate mills and factories , nor right of way, nor have they in hand any discernable revenues as an inducement to capitalists to carry out the project.

the meantime if there are any questions that I can answer at once, I would be glad to do so .
The whole question is one of cost. So far the answers "I have obtained from the electric companies have been, to say the least, foolish. They are perfectly willing to help spend the money but the schemes submitted are either vague or impractical.
So far I believe that the City of Buffalo might be lighted from Niagara Palls and even small powers of 10 to 20 horse power furn¬ ished but even in these cases the cost would be very little short if any, of erecting a large central station with a steam engine at Buffalo. I believe it would cost from $60. to $70. per year per horse power in Buffalo for large powers and 1 suppose this iB bey¬ ond the cost of steam power there. Have you any data as to the cost of steam power in large mills at Buffalo or Tonawanda?
Hitherto electric transmission of power has come in com¬ petition with small steam engines only, in which the cost of power is often $200. per h.p. per year for a 10 hour. (.service;. But when
it has to compete with large steam engines, it must furnish power for about $50.

Have you any data as to the cost of water power jis delivered from the turbines at Niagara Palls . To the $5. for water privileges must be added the cost of attendance and the interest and deprecia¬ tion on the cost of turbines, turbine pitts, water ways etc. I suppose this would make the figures $10. or even $15. per year.
I propose to take the figures at $10. if you have no other data for an estimate.
As to local distribution of power within the limits two miles, I believe power can be furnished in large mills for from $30. to $40. per year per h.p. but I will give better estimates as soon as I can collect the data.
As to Tonawanda, lighting can be carried on there with economy, I think, and small power furnished. As to large powers, all depends on the cost of steam power there. I believe that, with proper business and electrical management, it might pay.
In case of both lighting and power, however, currents of high tension (death-dealing currents) must be used in case of distance transmission.
The proper method of lighting Tonawanda would be by al¬ ternating currents, in the use of which the Westinghouse Company stands preeminent. Their system is eminently practical and car¬ ried out with regard to theoretical as well as comnercial efficien¬ cy. At the same time the high potential wires in the street are
highly dangerouse. I will consider the case more fully in my report Yours sincerely,

Dear Sir:-
Since writing my last letter I have received a letter from the Westinghouse Company about the lighting of Buffalo and Tonawanda in which they think that neither would pay commercially.
I agree with them with respect to Buffalo but not with respect to Tonawanda. The latter can be accomplished by the use of a higher potential than the Westinghouse Company use. The Brush Company have both an arc and incandescent system of very high potential and the Company make a success of anything they undertake. So far as I have been able to calculate, the lighting of Tonawanda would pay a little better than to use a steam plant there but even that is uncertain.
As to local distribution of power, my figures are now running from $35. to $45. for a radius of 2 miles. It seems more and more certain that electric transmission cannot compete with large steam engines beyond five miles.

Dear 51 i v : —
In reply to your question respecting the practicability anil economy of transmit tin;; power in large amounts through long distances (say in units of 1000 horse power for ten or twenty miles) by means of electric currents, I would say that the problem is not one which has ::ts yet received anywhere its practical solu¬ tion, and therefore we cannot say it is certainly feasible because it has already been done in such and such a ease.
barge amounts of power have been transmitted to distances of ons or tv;o miles and small amounts of power have been transmit¬ ted for lonr; distances, such as JJO miles, but the combination of largo amounts of power and Ion?; distances has not yet beer, realized in practice, and without doubt something now in the dimensions and proportions of electrical machinery must be developed in order to meet the requirements of such a problem r.is you propose.
Enough however has boon done to furnish a sound basis for general calculations and estimates, and having gone over these with great care in a variety of cusoa, I feel entirely satisfied that a plant could bo constructed for the transmission of 1000 horse power, through a distance of 10 or twenty milos, at si;ch a coot as would make each horse power, available at the end of the lino,cout from §10 to §20 pr. year J this including all interest on the cost of electrical machinery, line wires, buildings and other structure^ and the .expenso of icaintenanco as expressed in wages of attendants and cost of repairs. This does not include the cost of producing
[ENCLOSURE]

tha power by turbine a or otherwise at Niagara, which X have not examined or attempted to estimate.
In my estimation the difficulties, exponaivono as and wastefulness of any pneumatic method of transmitting power for such distances render it unv/orthy of consideration in this connection.
As 1.o the various methods in detail by which power may be conveyed by the use of electric currents, a full discussion would involve the writing of a tcoatiso, and I would su^ost that the most complete and satisfactory method to secure the best of these, would be to as!: for propositions from the principal electric companies and submit those to competent Klectric and .Mechanical Engineers for selection.

Hoar Sir:-
r°P1Jr to your recent favor asking me to report to joa, this woek, cm tlm practicability .roliab ility and cost, as can- parec. „o steam power of largo amounts of power transmitted toy elec- icioy from the falls of Niagara to Cities distant ten or twenty _ loo,l would say tint the subject is one demanding more time, but i _ia\e labored diligently to secure for you such in Formation os 11 enable you to judge of the value of the proposed method of ut.l-zjnf! -no power of Niagara River near the Palls, and the cost S Of the power there generated when carried to the distant places.
The cost of steam power, per horse power per annum, has not ? rlx™ vn* ono«Sh certainty to place it among t e known nua.n- los. I am clearly of opinion, that with coal at $5 00 v'r ton cost of steam power is not less than $4.5. per horse power per l!n» ^!0 best boilers and the inost improved engines. Very
manufacturers, who hare given much thought to the cost of their , 1 * ai'° t° let it as low as this price, those who do

remarkable for its quantity, reliability, and its cheapness 5? - 1
production, Such seems to bo the cano under consideration.
Having carefully considered the prospectus of the Niagara River Hydraulic Tunnel "« Sower Co., X am impressed with th e fo as - ability of the proposed plan of using this great water power* which always attracted the attention of manufacturers. I have no* sufficient data to enable me to fully verify all the estimates of .he Engineer of the Company, but I can detect no flaw in the ar¬ gument, as to practicability, and economy, and feel sure, the en¬ terprise, if carried out judiciously, will be t]s means of pre¬ sent ing manufacturers, wit’n nn ab ’undent, and cheap power, <n th a reasonable certainty, that tho power can bo carried twenty miles cost that should leave a fair margin of profit to tie Com¬ pany when offered at less cost than that c at the spot, or point of delivery*
V/hilc asked to report on tho cost or transmitting by elootri- ii ity only, I ib el it my duty to call your attention to other modes if transmitting motion, for the reason that each may have its place in certain cases. If the power of the water is to be used in ^ lighting, then the transmission of the electricity from the Dynamo lose to the water wheel directly to the distant city, will bo bet¬ ter than the transmission of the required power to Dynamos at tho distant placo . The question of uses of the power such as driving machinery or hoisting goods in warehouses, as well as the distance spanned in each case will point to th o most economic mode of trans- miss ion.

jl Niagara Palls, m, y. , liovr. 5th, 1889,'
| William B, Rankin©, Esq., jj New York City,
My dear Mr, Rankin© :
j| 1 have your letter with copy of one from Prof-
ji essor Rov/land.
let us consider some of his statements. He put3 [; the COQt of delivery of Electric power from Niagara Palls I t0 Buffalo at §60 to §70 per h.p. "for large powers." Is i; this true?
The Tunnel Co. will develop 100,000 h.p. at Niagara | Palls at a cost of §8,000,000, including a large amount of | real estate the revenue from which we will not consider.
The fixed charges upon the whole investment will be, say 5# interest - equal to §100,000, or §1.00 per h.p. for crude or | undeveloped power.
A plant of 10 Water Wheels of 1000 h.p. each equal jj t0 10»000 h.p. can be placed in a wheel pit and power brought to. the surface for §60,000, ji The fixed annual charges on this outlay are:
on the Capital ($60,000) §3,000 S# for repairs, *c. , 3,000 Attendance &c. 4,000.
Total, §10,000.
or §1.00 per h.p. per annum, and a total cost of §2.00 per h.p. on Shaft at Niagara.
let us consider the plant for transmission of 5000 h.p. to Buffalo to equal a cost of $1,000, OOo and we find.
Fixed charges of 5# on capital |
$50,000 |
Attendance &c, (estimated) . |
85,000, |
$75,000. |
|
Add $2. per h.p. for 8000 h.p. |
allow ing |
loss of 40X in transmission |
10,000. |
Total, |
$91,000. |
I V/hich Gives us about $18.85 per li.p. per annum at Buffalo. It must not bo forgotten that this sum pays l>% on all tho capital diroctly invested in the line and covers operating expenses of the same. This estimate includes the entire cost of right of way to Buffalo, and it follows that' tho ; second 5000 h.p. necessarily would cost loss than the first. ; These figures Beem to show that Prof. Rowland's estimate of $80 to $70 is entirely! erroneous.
Prom careful investigation wo find that the most
i' favorable showing that can bo made in Buffalo of minimum
|i -
j; of Gteam P°wer ia $30 lup. This is only attained
jj by larG® Plants working under the most favorable conditions, j! 1131(1 th0 average steam power oosts anywhere from §50 to $100 | per h.p,
| Briefly the conclusions must be as follows:
FIRST: That steam power in Buffalo costs from
$80 to $100 per h.p,
SECOND: That the Niagara power trahsnitted to Buf¬
falo will cost $17 to $20 per h.p. delivered at one or more central stations.
■
Prof, Rowland refers to the ability of the Brush Company to carry out anything they may undertake arxi we are
|;
: pleased to refer you to an offer signed by the President of ji thG Bru8h °°*> *Ir- Stockley, a copy of which you have, stat- j; inc th0 r willingness to supply the plait to transmit this jj power t0 and guaranteeing results such as I have
I; outlined above.
{: Prof. Rowland’s statement as to cost of local trans-
j; mlsBion to points within 3 miles of the initial power here I iB ^togethei- erroneous. Starting at the Company’s works [ hSre with a net ooat of *2. h.p. the added expense of
I tranallls3ion is simply the cost of wires, and poles or con- | duits.
In fact the transmission of power for two or three || miles on or near our lands is hardly worth considering, as i the cost cannot in any manner affect our enterprise. The ; Power may bo cheaply transmitted one to three miles by cable I and ovr Rlvor frontage is so extensive that 300 Manufactur- |i in® establisliments can be located upon our- lands, receive I wator frcm th0 Niagara River, and have their Water Wheels | within a few feet of their doors.
Finally do not let our friends commit the error of determining the value of tho Niagara power solely by its possible uses in Buffalo. Such U3e must and will be largo in amount and remunerative, but I make the prodiction that there will be a demand for it from all parts of the Country from individuals and firms seeking reliable and lasting pow¬ er that will build up a rovonuo which will fully care for the fixed charges upon the capital invested.
I Th0 ability of our Company to supply cheap power,
|| centrally located, with unrivalled shipping facilitios, muBt and will produce satisfactory results.
It may be presumption on my part to criticise the j opinions of a Professor of Johns Hopkins University, yet
^when one seeks the opinion and advice of a person supposed
I '%s
rto possess superior and authoritative knowledge upon a sub¬ ject and finds that person engaged in accumulating the opin¬ ions of other people upon which to base his ovm, it would ;J ,'8e em to be a plain confession of structural weakness; at if least in the direction of the subject matter under consider¬ ation, and any opinion so formed ought not to be valued, as | against those of Edison, Brush and others who have made j great discoveries in electrical matters and who know from | their ovm practical experience what theoretical men have had no opportunity of learning.

My Dear Mr. Edison,

Yesterday the Westtnghouse people opened fire upon them, claiming that the report was all wrong. They cabled for confirmation and 1 was able to send the tnclosed tn con- dens ed form over my own signature. Is this worth while to follow up in that benighted land? I also inclose some other matters whtch may be of interest.

Cable Dispatch sent by request to The London Daily News.
Referring to the accident last Monday morning where¬ by a horse was killed on Fourth Avenue and a police ser geant injured , will say that such occurrences have be¬ come very common since the introduction of the hig7i-ten- sion alternating current. The explanation is simple to anyone having experience with the peculiarities of that deadly current. In the first place although it was not at the time raining , everything was still saturated wi Si. water; a rusted telephone wire had fallen tnto the street and trailed against an « insulated// wire carrying the al¬ ternating current. The earth connection thus formed was but a partial one and vhen the horse shod with iron, struck the wire and pulled it taut, his body being more completely connected to earth, shunted sufficient cur¬ rent through ' tt to produce death.
He fell upon the wire and it is not at all unlikely that the contact of the rusted wire against the street car rail may have allowed sufficient current to &ufficin'rtt current to pass to heat the point of contact and finally produce an arc.
The body -of the horse vhen lying on-the paving stones, no longer formed so complete aground connection , and when the driver touched tt he received a portion of the current, but not sufficient to produce serious inju¬ ry. The police sergeant then came in contact with the wire between the horse and the pole and deflected suf¬ ficient current to knock him down and burn him. The ac¬ counts indicate that he too fell upon the wire and his assistant tn pulling him off received his quota.
This may seem improbable to English readers; it did to us at first but there have been so many similar acci¬ dents tn vhich the alternating current divided among sev erai living beings from a partially grounded wire, that we know tt is only too true. One case out of a dozen wtll suffice.
On the A.M. of Feb. 6, 1888, before dayltght, the driver of a grocery wagon on a prominent street tn Buf¬ falo, N.Y. , saw his horse fall. He tried to pull hts antmal up but fa tied and struck tt with hts wet vJhtp, re hetvtng sufficient shock to throw htm backwards tnto hts wagon. The ground was covered with snow and wet snow was falltng. Hts cries brought to hts assistance Isaac Morton, a porter for the Wagner Palace car Co., who seized the horse by the bridle and was instantly killed

Harold p. brown,
Subsequent examination showed that a telephone wire had uroken, one end falling into the street, resttng a- gainst an « insulat ed« wire carrying the Westtnghouse al¬ ternating current at 1,000 volts pressure . Had it been c'urrent ln either of these cases the grounding of the wire would have short-circuited some of the lamps a?id thus indicated to the station attendant that some¬ thing was wrong; or if an automatic regulator was used, mSP/fl,tgJ^ner,aZJy lhB caae> the voltage would have been tm mediately reduced and such accidents would have been im¬ possible. With the alternating current, however, there is no means of detecting at the station whether the cur¬ rent Passes through converters and lamps or leaks to the ground and returns through a human body and a stray wtre C07nPZaint the experts of the New York Health Department made an examination on the night of Oct. I4 » Iff®* °/ the ci™uits leading from the best equipped al¬ ternating current station in this city. One end of a v.0Zlmeterl was connected to earth and the other applied in turn to each terminal of nine different cir- onltV FtIU71 °/ these were in subways and the others on ry case Previous tests of insulation re- shovjed very high insulation. But with the rVZn r «n ^ Tnnt testS a difference of potential of from leo to. S00 volts was found to extst upon every cir¬ cuit, tne average betng 450 volts.
This is of course an Induced current but it is more than sufficient to produce death tn a human being touch - i7f ® vjtre whtle. making a ground connect ton. The armor of the underground cables and the moisture surrounding rnt *?s'uZ*tion °f overhead wires farmed a conducting pa*h for this induced current. This seems incredible and it ■would of course be impossible in a short laboratory cir¬ cuit. But when the wtres extend for miles the static capacity may easily, become very large. Ur. Hopktnson long ago pointed out the fact that converters were at the same time condensers and might be a source of danger out* think I was the first to show that the conductors themselves might be so regarded. In concluding the report of their tests the Health Dept, recommended that the pressure of the alternating current be limited to 2S0 volts. It is hoped that this limitation win be ad¬ opted since the high tension alternating current has al- ready claimed 40 victims , II of whom were killed in the oVrrthAr" Vkrl»hrr-' fie tyndon Electrical Review of Oct.

The duty on imported cables is 45*. Having had some experience in the importation of cables in this country, I think I can say positively that it would be impossible to get a cable in free of duty for inland use.
Should you desire, giving me the necessary specifica¬ tions, I can procure, through an engineer in London who has acted for some Companies that I am connected with, positive proposals from the various constructors of electrical cables in England, so that we may know exactly what time and money would be required for this branch of the business. In contracts involving several millions of dollars this gentleman acted as our inspector located at the works, and being a practical electrician having a personal acquaintance with all the manufacturers, his services would be use¬ ful and I can have them promptly.
As to jurisdiction in the Niagai-a River, it has been de¬ clared by the Government to be a navigable stream. It would be necessary to obtain the consent from the United States Government
Thos.A.Edison.g:
to lay a cable, and also from the towns along the line of the river -the latter necessity being in lieu of the State authority, by reason of the amendment to the Niagara Palls Company's charter, un¬ der which the necessary power has been conferred for our action, subject only to the approval of the townships. This latter can
readily be obtained at short notice.
Very truly yours,

Tho plan of -utilising tho power of Niagara river, in buildings to bo erootod on tho property of the Company • above the uppor RapidB, by meana of a tunnel or tail raoo from the property to tho bank of the river below tho falls, ns explained in the- panphlot issued by tho Company in 1886 end fully described by the then Division Engineer of the State of How York Mr. Thomas Evorshod , C.E., and indorsed by Mr. Elnathan Sweet, tho State Engineer and Surveyor, is one that oontnends itself as feasible , end no exception can bo taken to tho general plan of tho project as proaont- od by tho proposer of the ochomo. The question as before me is one of mechanical engineering, and finding no ac¬ curate surveys upon which to base an OBtiraato of cost or any details showing distribution of powers, I look upon lb*.

Tho proposed canal will lie about 6,020 feet above | tho mouth of tho tunnel and the property at tho option of j the Company extends so for up the river as to enable five othor canals to bo located, the last one being 6,600 foot | above tho one under consideration.
j Assuming 90 foot head to be tho most economical, but
!: leaving room for tho use of 96 feet head if wheels can be | obtained to work economically at the pressure and velocity j due to that head or fall, 1 hiare changed the grade of the ; main tunnel from a fall of one foot per hundred as laid : down by Hr. Evorshsd to 1/LO of a foot to the hundred, nom- | inally to a slope of .007. I maintain this grade or slope j up to tho canal under which lisa tho first cross tunnel.

and having found "that this constant decrease of water war—
; mats the change, I have adopted a slopo of .005 as tho bottom grade of tho rotnaininc G,C00 foot of tho main tunnel By this means I obtain a uniform 90* to 95* ho ad ovor tho jj whole land. Prom tho first cross tumsl, that is to say !| from a point 6,020 foot from tho mouth of tho main tunnel, the saiso size of cross section will bo maintained up stream for a distance of about 1,350 foot, to tho second oros3 tunnel, which tunnel. will aocontnodate 24,000 horso powox', and after thi3 amount has beon disposed of, the main tunnel :j will dooroaaa in siae in sections of 1,350 feet until tho last sootion is reacted, when the area of tho tunnel, will ;j bo decreased from 572 feet to 201 feot area or from a 27 ! foot tunnol to one of 16 foot diameter, the cost of each !, 3oction being loss than its predoooasor, while tho value | of the building si too will, bo uniform, so far as head of water is o<*icornad and mere valuable as boing near to Buf¬ falo and farther f rom tho dangorous part of tho stream.
In ny treatment of thia subject, I have had to take j: into consideration tho nature of tho rod? through which the j: water will pass , and in considering the use of watui* under i a hood of 90 feot at least, I have based ny calculations of i: volurao on tho loss in transmission from tho wheel to the j1 surfaoe and aim to deliver oaoh 1,000 horse poppr blooJc in such manner as to givo that poror at the first Jack shaft I; in each mill.

upon me the conviction that the main tunnel will pass r.
: through the shale that underlies the hard limestone rock, and which, while worked, with more oaso may he considered | less able to stand without lining. Frcm an examination of f this shale and the concurrent testimony of thoso who have i worked it I find that its name is misleading. It is, in | situ, a hard rook capable of standing a moderate velocity | of currant and yielding only to tho operation of frost in | conjunction with moisture. If, as I suppose will be the S case, the mouth of the tunnel will be wholly or in part in ; this shale I propose to protect it by masonry at the portal | and to keep out frost by closing the portal by gates that | shall extend as low as tho water line of the outflowing | water. By this means the tunnel will bo subjected to the action of water only, and that at such velocity, as haw : been found not destructive to the "Shale*.
Hie rook formation through which it is proposed to carry -the tunnel is the' same as ha3 been laid bare by the ; gradual reoedonce of tho falls to their present site.

Oho Ily dr tnlio Omal carries tho miter to tho mill sites below where this i tunnol will discharge and that at » groat cost in surface ; oanel more costly in const ruction and main tenon co thm un- lined tunnol s. Olio low cost of power obtained from tho said river by tho pro© nt enterprise must for many yoars be a bar to tho profitable onlare*nont of the Hydraulic

Sor the purpose of the present estimate the surface | 0“nal3 been plrnod 1300 root from each other, but tho
■ PJWbQain is ono that should bo onrofUlly considered in iso¬ lation to the kind of industries and tho yard room requir¬ ed by each, before the ground is laid out. Buffalo Street I passing diagonally through the lands may perhaps require j
rs -locating but the present estimate ia based on its rc- j
maining c\o now located. I can see no reason why it may j not be mode to serve as ono of tho many at roots in the j
| Croat manufacturing town proposed.
'Hie uniform distribution of power of 2,000 horso power to each wheel pit and the carrying of this in blocks of 1,000 H.F. to oech of tho mill sites one on either side of the pit, will enable the property to be rented to atf» ventage oven to small usors as tho rope transmission in some oases will enable whole rowa of small industries to take J>Sio place of any one large factory.
If tho present report reatlts in the prosecution of , the enterprise I fool sure that careful condderatlon of | 0och of tha »ony considerations that go to make up tho 5 w5l0l° will result in a very marked reduction from the p~er. _

Dear Sir :
I have undertaken to prepare for the February meeting at Kansas Citjf'of the Edison llfyr pames an evening entertainment, similar to the Lightning Protection talk at Nantasket, illustrated wi diagrams. In this case, however, the Bureau desires to' secure the practical co-operation of all pr; the business who will send within a week after receiving this letter any notes Central Station work not heretofore described, new devices or new methods of which they have accomplished, showing the progress of the business in their fii
Among such contributions may be included, for example, (I) statement of motor work ; (2) current sold to telegraph companies or for other special purpose: (3) interesting modifications of the ordinary methods of wiring, as in large buildings; (4) special lighting, as in theatres or public halls where unusual problems of distribution have been met , (5) original or special forms of switches, lightning arresters, ampere-meters, safety catches, &c. i (6) accounts of special difficulties with conductor, like electrolysis or obscure faults.
These descriptions should be accompanied when practicable by India ink drawings or sketches on pure white paper of any convenient size for photographing, say from 6 to 12 inches square, or samples of devices from which slides can be made, or if convenient photographs or lantern slides of standard stereopticon size, three and one-quarter by four inches. If you have any photographs of your station, or can obtain any, showing an outside view and the arrangement of your electrical apparatus, these will prove of great interest to many who have not had an opportunity of visiting you. If you do not wish to part vvith such photographs and will loan them to us, or will send us negatives from which slides can be made, we will see that they are carefully used and promptly returned.
Your co-operation is earnestly solicited. If you are to be present at the convention, and it is not con¬ venient to send any description at this time, we shall be grateful for a response to this letter, stating that you will be present in person and give a number of slides and accompanying descriptions. Thus we shall know to what extent we may depend upon you fora contribution. If you cannot be present, whatever signature will be shown, or read as your contribution.
By many short and interesting paragraphs we hope to greatly enhance the interest of this Convent You will appreciate the fact that any effort to be available should be prompt.
Please use the enclosed envelope for your reply.
Yours very truly,

Dear Sir:
We would like very much, if it is not too much trouble, to have you write a short paper for the coming Convention, detail¬ ing to the best of our present knowledge the proper practice with meter plates and solution to avoid oxidation. This will be a strictly private matter confined to Edison people. If you wish, the inclination can be given subject to future addition or alter¬ ation, but we consider it very desirable that at the Convention we should give some definite idea of what improvements have been made in meter work. Possibly your paper could be read in connect¬ ion with another one giving additional information as to details of meter work &c.
The Convention is held at 'Kansas City, Mo. , commencing Tuesday February 12th; we expect to leave New York Saturday Feb¬ ruary 9th.
Yours Very Truly,

Again I am reluctantly obliged to trouble you.
In closing a company for Toronto, Canada, I have had occasion to spend a couple of days with a Mr. Nicholls and a Mr. Carr of- that City. I have shown them everything that is to be seen here but before returning to Toronto they were very anxious to see Mr. Edison and the Laboratory. I satisfied them that the cornier • would beiimpossible, and then as a last resort', agreed to give-., them a letter to you. I am very sorry ind8ed to trouble you in the matter' but I am sure that a vew minutes time with them will be- well spent and inasmuch as you are acquainted in Toronto I pre¬ sume on your good nature in giving them this letter. Whey will probably call upon you tomorrow, Saturday morning.

Dear SirJ-
I have read your report on motor experiments with the deepest intorest; thoro are many points upon which 1 th ini: vie ought to have a most careful discussion.
At the Convention tho point was made that it is now of the greatest importance to the stations to have a motor which will show the total current output. The ampere indicators do not in all respects fill the bill, and X am told by station managers that they do not check with the meters of the dynamos. Moreover, as such a meter is an indicator merely and does not regiator, it requires many observations during the twenty-four hours to get the average of the energy expended.
Please give me a little more clearly y0ur idea of the connections of tho silver meter which you propose, and whether you think it possible to connect such a meter without introducing a very large and expensive resistance.

Mr A. E. Kermelly,
Edison Labratory, Orange, N. J.
Dear Sir: -
Mr Johnson has instructed me to have another edition of 50u0 copies of the Meter pamphlet printed for Mr. Hamner1 s order at Paris. I propose to add an appendix containing a record of the recent changes made in consequence of your researches. I also wish to add one or two points of interest; among them a mention of the small amount of energy expended in the registration of the Edison meter. I shall consider it a personal favor if you will glance through. the pam¬ phlet to refresh your memory, and suggest to me any other features of interest which should be enlarged upon, or which, perhaps,have been en¬ tirely overlooked in the preparation of the paper, as I am anxious that in sending out this edition to Europe we may say all that we. can in favor of the chemical system.
Very Truly Yours,
(fMismt (Malm light (§0.
