Mr. Charles Steele,
23 Wall Street
New York City.

My Dear Mr. Steele:-
Under inclosure I forward my formal letter to Mr.
Morgan, filled out and signed as requested!
On this occasion I would renew my assurances of esteem
and gratitude and also express the hope, that in a time not distant
I may be able to prove myself worthy of the confidence he has
placed in me.
Now, that all danger of conveying a wrong impression
to Mr. Morgan is removed by his kind acceptance of my proposal,
I would call to his attention, that I consider my fundamental
patents on methods and apparatus for the wireless transmission
of energy is the most valuable patents of modern times and, as
to my system of lighting, I am convinced, that it constitutes
one of the most important advances and is of enormous commercial
value.

Yours very sincerely,

(Now that I am getting used to his writing style I could probably go back and fill in some of the blanks. continuing forward for now. JLP)

Hi Ernst,

Nice work on the hand written letters, I can make out a few words but not enough (my doctor would do fine as he is writing much the same way). I seem to have lost some text formatting, the paragraphs loose their indentation (forum software is not wiziwig). Sorry...

Take care,

Michel

Perhaps you should print a few for your doctor to decipher Tell him it is for a great cause!
Don't worry about the formatting, I'll take care of that and the Q.A.
But at this moment I can not keep up with the two of you!
(don't let that stop you)
Forum software is WYSIWGL (what you see is what gets lost)...

Dear Mr Tesla:

The work of the shop is on the castings, switch and brusholders of the fourth independent break and Mr. Uhlman is also continuing the work on the pump.

I send herewith several press clippings. The N. Y. Herald, I note, has also engaged the services of Clarke for reporting the yacht races by wireless telegraphy, and it seemed to me that this may have been done through jealousy and in order to prevent other journals from obtaining reports by this new method.

This little item in to-day's Sun was, of course, the most interesting news to your employees here, although Mr. Uhlman and myself were much disappointed about the date of your return, if correctly reported. Prompted by the information contained in this latter article, we have immediately expressed the 24 mica condensers, thinking that they would surely be wanted, though no orders have been received to this effect.

Respectfully,

Geo. Scherff

Please tell Mr. Uhlman to prepare as quickly as possible an apparatus of the following description. A clockwork, same as the last two sent in every particular, except that there will be no *Unrune*, and on the small quick moving pinion there will be a fan with adjustable wings of aluminum. The latter need not be more than 1/2” wide and 1” long overall. I find that the fan is easiest made ans in sketch of a small light brass one on each side with light washers to hold down thin wings of aluminum slotted partly to allow the screw to pass through for purpose of adjustment and fastening in position. The fan should be as light as possible, Mr. Uhlman may make two. The fan should retard very little and should spin very fast when the wings are shortest. I do not think that it will be necessary to put in stronger springs in the clockwork, as the performance of the springs is much smaller than needed before. Now, the shaft of large wheel should be strong as before and longer on the side of the fan, and on the opposite side a copper contact spring should be fixed to connect shaft surely with the clockwork. No spring of this kind is needed on pinion shaft. The shaft of the large wheel will carry on the fan side device similar to those of which a number was sent to me, only I shall want this device a little modified and made much lighter than the former ones. I shall describe in detail. The...

... glass tube should be 3/8 inch inside diam.. The brass plug when in place, will be 1/16” short. All the brass should be as light as practicable. The hole reamed which is to fit on shaft of wheel should partially extend in to the thick part of the base plate (not through in which carries the whole, and Mr. Uhlman should try to boil the thing together so that the thick part is at, then (toast?) 9/16” thick. I think he can make it 1/2” for I need be more than 3/16” for sealing wax, that is, the outer brass shall need not stick out more than that above the end plug.The tip not the end should project no more than 1/8” beyond the rest and should be say 3/16” in diameter, as I want sufficient friction to stop the clockwork. This he will clearly see later. Against the end of the end plug there will be pressed a rather stiff copper spring, which will be fastened to the back part of the lever of a ____________ sounder is the latter being _____ to the fibre base carrying the whole apparatus and binding posts as in (nil?): for sounder ends placed so that the parts that is, the both magnets can be easily connected in series (sketch) and two besides, one connected with base of clockwork and the other with the lever of sounder respectively with the brass frame & sounder. To insure good contact of the lever with the frame, a light copper spring may be conveniently fastened, as we have done on some sounders before. The apparatus assembled will appear as in sketch. Normally, that is when current is flowing through magnets of sounder, the copper spring or...

... lever fastened to aluminum lever of the cover will press against tip (C) of device (D) and will prevent the clockwork from turning; but when for a moment the armature is pulled down, two things will happen, the contact with device (D) will be broken and at the same time the device will turn more or less, as the case may be. Mr. (Opitz?) made me some time ago something similar when I needed it for the boat; and I like to have one as soon as practicable in some I am making.

Mr. Uhlman may modify the details, as I have no time to enter into that at present. He should cut off a good part of the lever of the sounder, as I notice that it is unnecessarily long, and in general reduce the size, so that it will go into it, small space if practicable. Make two of this kind and send at least one as soon as possible. The sounder should be of the smaller size. (there are two size in the market and it should be well made. The movement of the clockwork should be quick when release occurs. This will ________ adjusted by cloning a _______ through the sounder for a moment. The clockwork should also instantly stop when the lever is against the upper stop. All is intended for quick movement. The sounder should be freshly wound, .I would use wire No. (30?)and so that back leg will have resistance of _____ ohms. But that is of little importance as I can make many more fixation of this (thing?) myself. The...

... insulation is important: Besides, this apparatus should be MADE AS WELL AS POSSIBLE. I want a box that is fill with small batteries, so arranged as to go in a small space and conveniently connected by a flexible cable and plug so that I can change any number of batteries ___________ small brass pieces which screw on the carbon studs instead of the ordinary screws. These pieces should be such as to allow connection to any point of the series by means of a cable and plug. The top of the box will have, of course, holes for the insertion of the plug and should be easily removable to change quickly a spoiled battery and use small type 0. (K?)I want also six resistances wound on spools very small about the size of silk thread spool anti-inductively. You can use wire No. 36 or 40 (I think there is some in the laboratory ______ resistance. I expect may be 2000 – 4000 ohms.

Attend to this at once, Mr. Loewanstein will probably help on this.

Dear Mr Tesla:

Your letter of Sep. 19th, with check of $200, for shop expenses, was received this morning.

I have delivered the message to Mr. Unger; he says he is desirous that you should not inconvenience yourself in the matter.

Mr. Lowenstein has not yet arrived. Mr. Uhlman says he will take pleasure in co-operating with him in any work he may bring along.

The work of the shop to-day is on the castings, the switch, connecting rod and other brass parts of the fourth break and on the pump.

Inclosed I send a statement of the laboratory expenses up to date. The salary account this week is $133, seventeen dollars less than usual, which is due to the absence of Mr. Seibel, who has not been working the past week, being laid up with rheumatism. I would like to know whether I am to pay him or not when he returns to work.

Mr. Czito's salary for this week I have sent to his wife, as he requested me to do.

Dear Mr Tesla:

Your checks for the University Club, Edison Electric Illuminating Company and Non-Polarizing Dry Battery Company were received this morning.

The work in the shop is on the castings, on the brush-holders and other brass parts of the fourth independent break and on the pump.

Mr. Lowenstein has not yet returned, but a note, mailed on the train, was received from him this morning, saying that he would arrive to-morrow, Tuesday.

Last night, I happened upon the article by McGovern, which seems to have called forth the several letters from India and Australia. I forward it, thinking it may have come to your notice.

Dear Mr Tesla:

The work in the shop is on the castings, pulley and different brass parts of the fourth break.

Mr. Lowenstein has returned to-day and work on the coherers, about which he had instructions, has also begun.

Mr. Uhlman says some further improvement has been made in the pump; the same works now very well and gives a very steady light, and duplicates of it will be made for the other breaks. I have not forgotten your recent censure for writing so often on this subject and wish to beg your pardon for touching upon it again for the last time I hope.

The mail to-day consisted of the inclosed bill and two applications for positions, one from Mr. Lee De Forest and one from Mr. Barnum C. McClusker. I have informed both applicants of your absence.

Dear Mr Tesla:

Your letter giving description of clockworks, sounders and coherers to be made was received this morning. Mr. Uhlman says work on the different devices has begun at once, and they will be produced as rapidly as possible.

I inclose two bills received to-day, one of which is from Foote, Pierson & Co. For an ink writing register delivered May 11th, upon looking over the books I find that a similar instrument was received on April 19th, and that a check of $38.75 was sent for the same on April 20th. If I remember correctly, this first instrument did not suit your purposes, and was returned when another one was sent on May 11th. I have telephoned to this effect the Foote, Pierson & Co. They know that one instrument was returned to them, but say your order was for two. However, they are not sure that both have been delivered. I am quite certain that only one was received which was sent to Colorado. I have inquired of Mr. Lowenstein, and he says he knows of only one there. If this is right, there would be $3.75 to your credit, as the present bill amounts to only $3.75.

As to-morrow and Saturday the banks will be closed on account of the Dewey celebration, and in order to comply with your wish to have the men paid on time by all means, I obtained to-day at the Chatham Bank $100, which, together with the amount on hand, will be sufficient for the pay roll next Saturday. The sum will be charged against your check when it is presented, as before. The Treasurer of the bank consented to advance the money only after considerable hesitation and said, he did not see how he could do it again, unless you send him written authority.

Mr. Lowenstein has told Mr. Uhlman and me something of your wonderful work there, and we know that, instead of a century you are a thousand years ahead of the others.

Respectfully,

Dear Mr Tesla:

The shop today is occupied on the clockwork, sounders and coherers, also on the work of Mr. Loewenstein brought, and Mr. Clark continues to work on the castings of the fourth break.

The mail obtained to-day at the Waldorf contained, besides journals, press cuttings, the included letter and invitation, and also invitations for social functions from the Country Cycle Club and from the Strollers. I have informed Prof. Carus that you are still in Colorado and that his letter has been forwarded. The number of the Monist he refers to has not yet been received; I will send it as soon as it arrives.

Mr. Uhlman and I have come down and tried to advance the work as much as possible, and we are very sorry for the delay caused to the work in hand.

I inclosed a statement of the expenses and pay roll of this week. Mr. Seibel has not yet returned to work. Mr. Loewenstein says, he receives two weeks salary, as last Saturday he was on his way here. I am awaiting instructions, whether or not to pay Mr. Czito's salary to his wife; he told me he would speak to you about the matter.

Dear Mr Tesla:

Your letter of Aug. 29Th, with check of $250 for laboratory expenses, has just been received this evening. I did not go to the bank last Saturday, as I feared that such a course might displease you.

Mr. Uhlman says, he will make a diagram of the pump and give fuller explenations of the same to-morrow. He says it is quite different than you have understood.

The work of the shop continues on the armature, shaft, ball bearings, teeth for the disk and minor parts of the third independent break.

The inclosed letters were obtained to-day at the Waldorf.

Dear Mr Tesla:

The work of the shop is on the pulley and shaft, the pump, cover, armature, disk and teeth and wings for the fan of the third independent break.

Mr. Uhlman sends herewith a sketch of the pump and explains as follow:

The pump which we have been working on is for the third independent break. The flow of mercury is regulated by inserting a suitable shaped plug into the pump. The mercury thus comes out in a solid stream at slow speed; the mercury leaving the pump is caught up by a suitable receptacle to insure a steady feeding of mercury into the grooves of the pulley, thus giving a steady flow from the pump.

The overflow feature without the pump is adopted in the design of oscillator. I am working on, but not in the independent break just finished. In June I sent a sketch of an oscillator with design and features of the independent break embodied.”

The inclosed letter from Melbourne, Australia, was forwarded by the Pearson Publishing Company, whom I have thanked for their courtesy.

I inclose also a bill from Mr. Habirshaw and a statement of the expenses for the past week.

Permit me to again inquire about your health and the success of the experiments. I saw a notice in the technical journal a few days ago that Mr. Clark had been making some experiments in New York Bay. He succeeded in telegraphing three and a half miles, at a distance of 5 miles the signals were no longer intelligible.

Sep. 6th, 1899


Please immediately upon receipt of this letter, tell Mr. Uhlman to prepare mica condensers as follows.

The mica should be of the best quality and say 3” x 3”, or better 4” x 4”, if the price is not much higher. The sheets should be split very thin; this is important, but I cannot just now say exactly how many thousandth. Perhaps Mr. Uhlman will find it practicable to make it not more than 3/1000, but perhaps he will find that it is too thin. At any rate, I want it as thin as possible, but still not so that there might be holes in it. The sheets should be as uniform thickness as practicable. Now, on each side thinfoil, the thinnest, should be glued with very thin French varnish, slightly warm. The space around should be 1/8”, that is, the mica should be so much larger. I want 24 condensers, each containing 6 sheets of mica. To protect the frail structure Mr. Uhlman may use two sheets of thin brass, one on each side, which will have screws (one each) for fastening the wires to the terminals of the condenser. Mr. Uhlman will devise some practical and inexpensive plan for fastening or keeping the brass plates (not more than 1/32” thick) together. I expect to write again about some other work to-morrow. Mr. Uhlman may keep the workmen busy between times on a fourth break, we shall want it.


On the lapping part say 1/4”.

Mr. Loewenstein is not feeling better, as he has telegraphed Saturday; he says he will sail for Europe next Thursday, if at that time he receives our consent and testimonial.

The inclosed letters were received to-day. I have informed Mr. Zucca, that you are absent on a scientific expedition, and acknowledged the receipt of the other two to the writers.

One of the clockworks was expressed to-day, together with two coherers, one of aluminum and one of brass, like the previous ones, and a pin for the adjusting the set screws of the rocker arm. Mr. Uhlman says he was obliged to follow this construction, because the contact of the spring on the end of the coherer was not sufficient to stop the clockwork, even under pressure, and platinum contacts had to be inserted in the ends of the coheres, as the blunt contact soon became covered and not cunducting. The magnets of the sounder are wound with No. 34 wire as directed.

The resistances are being wound and will be sent off to-morrow; the battery box, Mr. Uhlman thinks, will be ready Wednesday. Mr. Merckling will bring the box to-morrow.

Mr. Uhlman says he will await further instructions in regard to the point receiver. He has made a design with adjustable points and adjustable vacuum, but no work has been done on it in the shop.

Dear Mr Tesla:

The battery box and resistance spools have been expressed to-day. The resistance of each of the spools, Mr. Uhlman says, is between 3750 and 4000 ohms, and they are wound anti-inductively, as directed, with No. 40 wire. Mr. Uhlman regrets the delay in getting out the battery box, which was caused by the absence of two of the men.

The inclosed plug belongs to the box, it was overlooked in shipping.

The registered letter, for which the card was received this morning, will be forwarded to Colorado Springs by the Post Office authorities, as the writer has directed that it is to be delivered only to you personally. The writer, A Dr. Cruzan, has previously addressed to you three letters, which are here in the office and in answer to which I have written him that they would be laid before you on your return from a scientific expedition. As these letters are to a great extent unintelligible, I have made no special mention of them.

Dear Mr Tesla:

The work of the shop continues on the second clockwork and on the fourth break. Mr. Uhlman thinks the clockwork will be finished next Tuesday or Wednesday.

The mail obtained to-day at the Waldorf contained, besides journals, press cuttings and the inclosed letter, several appeals for charitable societies,
in reply to which I have sent information of your absence from the City.

A copy of the issue of the Monist, mentioned in Prof. Carus' recent letter, was also found at the hotel and has been forwarded under separate cover.

Another letter was received from a firm in Bombai, India, desiring to become agents for your new light. I have answered that the proposition would be laid before you for consideration on your return.

I inclose also a blank for the annual report of the Nikola Tesla Company, received to-day from the State Comptrollers Office, together with a copy of the answers as given last year. I beg to ask if I can do anything in regard to this matter, also if there will be any change in the answers to question 20 and 21.

I am sorry to say the clockwork did not pan out right, besides, it is too big for a box I designed here. Mr. Uhlman should try to make the stop in the manner indicated by me, and all as small as possible. There is a finer clockwork to be had. He can make the lever bear upon a disk of larger diameter, or stop the clockwork by the magnet in the manner of an escapement. This ought not to be difficult.

As to the point receiver, the chief is to have the points meeting in a very narrow tube and have the exhaustion 75 millimetres pressure, or perhaps 100 mm. The tube should be as in the sketch, platinum wires sealed in glass all together, only very fine, sharpened point (polished) exposed. The points as closer together as possible, perhaps it would be best to make them actually touch; being very fine, I can burn the points off with the current so as to leave microscopical space between. To get the pressure right, the glass blower should connect a tube to a gauge and seal off, when the right pressure is attained.

I would like two tubes made like this.: a tube with two compartments, at a a minute hole drilled through by a jeweller, a plate of aluminum and wire in each compartment. The tube about 1/4” to 3/8” in diameter, 1/2” long. Pressure 75 to 100 mm.

__________________________________________________ ________________

Tesla Correspondence #208


I have just received clockwork, but cannot tell how it will do. It was an important point to break the current just on the place where I indicated it in my letter. Tell Mr. Uhlman better not to push the other clockwork until further direction.

Will you tell him to prepare about 6 small lamps 3 volts as follow: A platinum wire, very finely pointed and covered with glass to nearly the point, will be melted on the side of the lamp so as to barely touch the filament. The lamp with wire is illustrated in the rough sketch.

The glass stem need not to be very thick. I would want, say three lamps, in which the wire touches certainly the filament, and for the other three, if it does not exactly touch, never mind, but it should be as close as possible. But the best way would be probably to make them all so that the wire just touches gently, then I can burn off the fine point by passing a current from the wire to the carbon. Tell Mr. Uhlman not to do it himself, as I want it done just in a certain way.

I furthermore want a small Porter motor, the larger size and better make (there are two kinds), improved so arranged as to drive a small interrupter wheel fastened on its shaft. A small brush of thin platinum sheet should bear upon the wheel, and Mr. Uhlman ought to try to get as many breaks per second as he dare. The current will not be very large. The best way is, perhaps, to place on the shaft (insulated from the same) a wheel with teeth milled so that the brush will break the current by jumping from tooth to tooth, but I want the time of interruption long and contact very short and still a great number of breaks.

P.S. The motor should be mounted on a fibre base and there should be four terminals: 2 on motor and 2 on break, (wheel and brush). I now remember that for some experiments I want two brushes insulated from each other, to bear on wheel breaking the current at the same time exactly.

Dear Mr Tesla:

Your note of Oct. 13Th, together with two checks for Mr. Unger, and also the checks for The Lambs and for the Society for the Prevention of Cruelty to Children, has been received this morning.

The book “Transmission de l’énergie électrique sans fil” has been ordered through the D. Van Nostrand Company; they did not have it in stock.

Mr. Loewenstein sailed for Europe the day following the receipt of your letter regarding him. He said that, after his health had improved, he would be married and would probably return to this country next spring, and he intimated that very likely some dispatches which has passed between him and his fiancée, who was about to come over here, had given rise to a misunderstanding. He told me he would write himself and explain the whole matter to you as soon as he was able.

The second clockwork is expected to be ready for shipment Wednesday morning and in the absence of other orders, the work on the fourth independent break will the be taken up and completed as rapidly as possible.

Dear Mr. Morgan:-
1. I respectfully apologize for disturbing you at a
time, when your mind must be filled with thoughts of a more seri-
ous nature than usual.
2. My efforts are now centered upon that element of the
plant I am constructing, on which the effects, at distance chiefly
depend.
3. The transmission of energy by my system is exception-
al in this respect, that a small increase in the sum invested in
the apparatus results in a very great increase in the performance
of the same.
4. On the basis of many estimates which I have ______
___, you _____ it as not being far from true that, if the sum

(I can only make out a few words here n there until)

7. What I contemplate and what I can certainly accom-
plish, Mr. Morgan, is not a simple transmission of messages without
wires to great distances but ___ ____ transformation of the en-
tire globe into a sentient being, as it were, which can ___ in all
it's parts and through which thought may be _____ as through
a brain.
8. Consider that from a single plant I can operate,
at the the same time,- not a hundred, or a thousand, or even a million,
but thousands of trillions-a practically infinite number- of
instruments, each costing no more than a few dollars, situated at
all parts of the globe.
__________________________________________________ _____
Morgan 0023
9. Only two power plants, one located, say, on the old
continent, and the other in America, can transmit more messages
than millions of the present cables working continuously at full
capacity, and this would be true even if their working capacity
were increased a thousandfold.
10. You only need to realize this great truth to at once
recognize, that as a means of conveying general knowledge the
cables are absolutely and hopelessly doomed. They may be employed
for special purposes, but not for the distribution of general news.
11. Here is a result, Mr. Morgan, of overwhelming humani-
tarion as well as financial importance, worthy of your energies,
and one that would give you a new hold on the world, which has been
already benafacted so much by your genius and activity.
12. Believe me, that however keen my satisfaction would
be in completing this great work, an equal pleasure I would find
in telling to the whole world that it is yours more that my own.

With expressions of admiration and gratitude believe me

Ever yours most faithfully,

Dear Mr Tesla:

Your letter and note of Oct. 14th were received this morning.

The work on the Porter motor has been at once taken in hand, and Mr. Wagner has been sent for to do the work on the lamps, he will come to-morrow afternoon.

Mr. Uhlman says the second clockwork is completed and almost assembled, but he will defer its shipment until further instructions are received in case there are any changes to be made. He says he has endeavored to construct the make and break device more simply than in the first clockwork.

All the papers on the resistance of metals at low temperature, by Prof. Dewar, that could be found, have been mailed under separate cover.

The inclosed letter from Mr. Lagelouze was received to-day. I have informed him that the same would be forwarded to you in Colorado.

A notice was received from the Royal Institution that the annual dues of L. 5. 5. 0. are payable, and I have sent the amount by postal money order.

Mr. Uhlman says he will try hard to carry out your suggestions and get out a clockwork as soon as possible. Mr. Wagner is now here working on the small lamps. The work on the Porter motor break is progressing as quickly as possible.

The photographs have also arrived, and I am going to deliver them this evening on my way up-town. Mr Uhlman and I have marvelled at them and think that the magnitude of those discharges is only surpassed by the magnitude of the work being achieved, and we have regretted that we cannot be actual witnesses to these wonders.

The card for a registered letter, inclosed in your note received yesterday was presented at the Post Office, and I was told that this is only a second notice for the letter of Dr. Cruzan and that the same had been forwarded to you on Oct. 11th.

Dear Mr Tesla:

The work of the shop continues on the Porter motor break and on the fourth independent break.

A little delay is caused in the glass blowing work by Mr. Wagner being unable to absent himself from his present place to-day, he will finish the job Saturday.

Mr. Uhlman says the second clockwork has some improvements over the first one and seems to work so perfectly in accordance with your wishes, that he thinks it is advisable to send it; a box is being made for it and it will be expressed in the morning. Mr. Uhlman also inquires, if he should find a smaller clockwork and build an apparatus which will take up as little space as possible and so as to go into the space allotted for it. He says he will spare no efforts in trying to construct an apparatus to conform with your wishes.

Mr. Uhlman says he will start at once to build the mica condenser as directed, and try to better the oscillator in any way possible, when it arrives.

He hopes to have all the glassblowing finished to-day. The delay is due to the fact that Mr. Wagner could not be had. He is working on the small lamps now and, if they are finished in time, they will be sent to-night yet. Several of these lamps, Mr. Uhlman says, are not what they ought to be, as Mr. Wagner has found the task of making them very difficult; the best six that he has made will be sent.

The small break will also be ready on Monday.

I regret to say that the glass tubes are still not ready for shipment, because Mr. Wagner could not absent himself from his place to-day. The small lamps could not be finished Saturday evening, as Mr. Uhlman found, when the lamps were ready to be exhausted, that the pump valve would not open after being so long inoperative. He has tried all day, and is still trying, to make the pump work, but so far without success, and if it is necessary, the tubes will be sent to Greiner in the morning to be exhausted.

The small break will be shipped to-morrow.

Dear Mr Tesla:

Your check of $200 for the laboratory expenses and order for a checkbook were received this morning. The latter herewith forwarded.

Mr. Wagner has been entirely unsuccessful with the tubes with glass diaphragm and aluminum disks, owing to the fact that the aluminum leading-in wires would always burn up in uniting them with the glass. Mr. Uhlman is now having platinum wires attached to the aluminum disks, and Mr. Wagner will try again to make the tubes in the hope that this time he will succeed.

The work on the mica condenser is so far progressed as to await the arrival of the oscillator.

Mr. Adams personally called up on the telephone to-day and inquires if you have returned, saying that he wished to have some of the stock of the N. T. Company transferred. He said he would wait until you come back and sends his best wishes for your health and success.

I send also another bill for mica; the first lot obtained proved to be insufficient for the condenser.

Mr. Uhlman and I have much regretted the long delay in forwarding the glass tubes, as well as the unsatisfactory character of the same, all the more so as Saturday evening, after finishing up, Mr. Wagner asked for the sum of twenty dollars for his labor, which price we thought exhorbitant. Some of the work was done at his home and he said that he had worked altogether 48 hours, but Mr. Uhlman thinks that this is due rather to his lack of skill than any extraordinary difficulty in making the tubes.

J.P. Morgan, Esq.

New York City
Dear Mr. Morgan:-
Under incolsure please find assignment of patents which
were granted to me recently and which fall under the terms of our
agreement. They cover certain new departures in the transmission
of electrical energy through natural or artificial channels, and
it's utilization for various purposes. I am securing the rights in
Some of the foreign countries.
Pardon me for trespassing on your valuable time in order
to give you, on this occasion, in the fewest words a clear idea of
the bearing of my patents relative to energy transmission so far
assigned.
Any problem of this kind will present itself to you in
three aspects-first, the production of energy, second, it's
transmission, and third, its utilization at the distant point
As to the first, my patents cover novel methods and ap-
paratus for the production of electrical effects of virtually un-
limited power, not obtainable in any other ways here to fore known.
In regard to the second my inventions cover the only
practical and economical method of transmission by conduction
through the earth with "tuned" circuits. They also cover new
methods of transmitting great amounts of energy for industrial
purposes without wire. The practical significance of my system re-
sides partially in the fact, that the effect transmitted diminishes
only in a simple ratio with distance, whereas in all other
systems it is reduced to the proportion to the square. To illustrate,
if the distance be increased one hundred fold, I get 1/100 of the
effect, while under the same conditions others can obtain, at the
very best, only 1/10,000 of the effect. This feature alone bars
all competition.
In regard to the third, there are only two ways possible
of economically utilizing the energy transmitted for the production
of qualitative effects: either storing it in dynamic form as, for
instance, the energy of well-timed thrusts is stored in a pendulum
or by accumulating it in potential form as, for example, compressed
air is stored in a reservoir.

One of the latter is a proposition to become agent or manufacturer of your new light for Sweden, Norway and Denmark; the writer of the other one wishes to dispose of some water-falls. I have replied to both of these letters that they would be laid before you on your return from a scientific expedition.

Respectfully,

Geo. Scherff

Dear Mr Tesla:

The inclosed note was received this morning from Mr. Loewenstein, together with fifty dollars in bank notes. The receipt of the same at first puzzled me, but afterward I remembered that Mr. Loewenstein mentionned that you had advanced him some money, and I suppose this sum is sent in payment of his debt.

The work in the shop to-day is on the winding of the armature, on the ball bearings, pump and minor parts of the fourth independent break.

Respectfully,

Geo. Scherff

Dear Mr Tesla:

The work to-day is on the pump, winding of the armature and on assembling of the finished parts of the fourth break. As the break is now nearing completion, Mr. Uhlman requests orders for further work.

I beg to call attention to the matter of the corporation tax, the report for which is returnable on November 15th, if I remember correctly.

Respectfully,

Nikola Tesla, Esq.,
Colorado Springs, Colo.


Dear Mr Tesla:

The work to-day is on finishing the fourth break and on making such tools as are constantly needed in the shop.

As many parts of the independent break and the oscillator embodying the features of this break are identical, Mr. Uhlman begs to inquire if you might not think it advisable for him to go ahead and build the oscillator, or, at least, finish such parts as are alike, that is, the pulley, magnets, magnet seat, armature and commutator, for all of which castings are still on hand. He says, there would be two additional castings required for this oscillator, namely the condenser case and stationary shaft castings, which will not be much changed from the original ones, and he asks if he should have patterns made for these.

Respectfully,

Geo. Scherff

Nikola Tesla, Esq.,
Colorado Springs, Colo.


Dear Mr Tesla:

I beg to acknowledge the receipt of your favor of Nov. 7Th, together with checks for Munsell & Co., The Players, Am. Museum of natural History and $225 for shop account, of which $50 has been paid to Mrs. Czito, as directed.

The fourth break is now practically finished, only a little work remaining to be done on the pump, which will be completed by to-morrow evening. Mr. Uhlman says the machine runs very smoothly and quietly.

Mr. Uhlman has put the men to work on such parts of the break which are the same as those required for the oscillator, so that the shop is kept busy until other orders are received.

The book on energy transmission has had to be ordered from Europe. Mr. Speirs told me to-day that he expects the same to arrive in a few days, I will forward it as soon as it is received.

Respectfully,

Geo. Scherff

Dear Mr Tesla:

the work of the shop is on the pump for the fourth independent break and on the castings and brush-holders of the oscillator.

Mr. Lewis, whose recent letter in regard to a souvenir for Mr. Insull I forwarded, telephoned this morning and asked me to write that this work is now nearly completed and will be presented to Mr. Insull probably next week. A few lines from you and your photograph, he said, would be valued very highly, and asks, in case you intend to make such contribution, if you would be kind enough to send it soon.

It appears, from the inclosed articles from the Electrical Review, as well as from reports in general in the daily press here, that Marconi's success was not as glorious as the New York Herald would have believe.

I inclose a statement of the expenses for the past week.

Respectfully,

Geo. Scherff

Dear Mr Tesla:

The fourth break is now entirely finished; it runs smoothly, like the others, Mr. Uhlman says, and its speed is 1900 revolutions per minute.

The work is on the castings, brush-holders and other brass parts of the oscillator. The shop is fully occupied by this work.

A letter to be returned to Mr. Loewenstein was received this morning from Colorado Springs, and has been forwarded to him.

Respectfully,

Geo. Scherff

Morgan 0026
In the patents assigned last spring I have embodied the
first, and in some of those now assigned the latter principle. My
rights on both are fundamental.
Referring particularly to telegraphy and telephony, I
have still in the Patent Office two applications, one of which is
allowed, while the other is about to be allowed. I have kept them
back for a number of reasons. In one of them I describe and claim
discoveries relating partially to the transmission of signals
through the earth to any distance, no matter how great, and in the
other a new principle which secures absolute privacy of messages
and also enables the simultaneous transmission of any desired
number of messages, up to many thousands, through the same channel
be it the earth or a wire or cable. On this latter principle I
have applied for patents in the chief foreign countries. I con-
sider these inventions of extreme commercial importance.
Hoping that I shall soon be able to satisfy you that
your generosity and confidence in me have not been missplaced,
I remain,

Yours very respectfully
