Edison in those days rather liked the modest coffee-shops, and mentions visiting one. "When on the New York No. 1 wire, that I worked in Boston, there was an operator named Jerry Borst at the other end. He was a first-class receiver and rapid sender. We made up a scheme to hold this wire, so he changed one letter of the alphabet and I soon got used to it; and finally we changed three letters. If any operator tried to receive from Borst, he couldn't do it, so Borst and I always worked together. Borst did less talking than any operator I ever knew. Never having seen him, I went while in New York to call upon him. I did all the talking. He would listen, stroke his beard, and say nothing. In the evening I went over to an all-night lunch-house in Printing House Square in a basement--Oliver's. Night editors, including Horace Greeley, and Henry Raymond, of the New York Times, took their midnight lunch there. When I went with Borst and another operator, they pointed out two or three men who were then celebrated in the newspaper world. The night was intensely hot and close. After getting our lunch and upon reaching the sidewalk, Borst opened his mouth, and said: 'That's a great place; a plate of cakes, a cup of coffee, and a Russian bath, for ten cents.' This was about fifty per cent. of his conversation for two days." The work of Edison on the gold-indicator had thrown him into close relationship with Mr. Franklin L. Pope, the young telegraph engineer then associated with Doctor Laws, and afterward a distinguished expert and technical writer, who became President of the American Institute of Electrical Engineers in 1886. Each recognized the special ability of the other, and barely a week after the famous events of Black Friday the announcement of their partnership appeared in the Telegrapher of October 1, 1869. This was the first "professional card," if it may be so described, ever issued in America by a firm of electrical engineers, and is here reproduced. It is probable that the advertisement, one of the largest in the Telegrapher, and appearing frequently, was not paid for at full rates, as the publisher, Mr. J. N. Ashley, became a partner in the firm, and not altogether a "sleeping one" when it came to a division of profits, which at times were considerable. In order to be nearer his new friend Edison boarded with Pope at Elizabeth, New Jersey, for some time, living "the strenuous life" in the performance of his duties. Associated with Pope and Ashley, he followed up his work on telegraph printers with marked success. "While with them I devised a printer to print gold quotations instead of indicating them. The lines were started, and the whole was sold out to the Gold & Stock Telegraph Company. My experimenting was all done in the small shop of a Doctor Bradley, located near the station of the Pennsylvania Railroad in Jersey City. Every night I left for Elizabeth on the 1 A.M. train, then walked half a mile to Mr. Pope's house and up at 6 A.M.
