Abstract

re your letter 15th, I enclose copy of a contract in duplicate which you should execute for the B & O R. R. This contract gives you the right to use the Phonoplex, but that if you desire to discontinue use of any circuit, all royalties in connection with it cease from the time the instruments are disconnected. Our intention is that royalty be paid only on circuits in actual use. TAE reduced yearly royalties on Duplex and Quadruplex equipments from $150 and $250 respectively, to $100 each, making our royalties for all kinds of equipment uniform. This is very reasonable. # re purchasing instruments from us, we will supply them at actual cost, or you can buy them from Bergmann & Co. We make no profit on the sale of instruments, our revenue being derived solely from royalties. When Logue's services are required we charge for his bare expenses only, paying his salary ourselves. Logue has been making a test on the Pennsylvania lines of a chromic acid battery and found that it gave two weeks of excellent service. Chromic acid can be bought in quantities for about 16 cents a pound, which is not any more expensive than Bi-Chromate of Potash, in fact much cheaper than it, considering the extra amoung of work obtained from the cells. # I will send a bill at once for the equipment of your Washington circuit. I am sorry I cannot enclose it in this letter.
