Very slowly these lectures, and the tireless activity of Hubbard, pushed back the ridicule and the incredulity; and in the merry month of May, 1877, a man named Emery drifted into Hubbard's office from the near-by city of Charlestown, and leased two telephones for twenty actual dollars--the first money ever paid for a telephone. This was the first feeble sign that such a novelty as the telephone business could be established; and no money ever looked handsomer than this twenty dollars did to Bell, Sanders, Hubbard, and Watson. It was the tiny first-fruit of fortune. Greatly encouraged, they prepared a little circular which was the first advertisement of the telephone business. It is an oddly simple little document to-day, but to the 1877 brain it was startling. It modestly claimed that a telephone was superior to a telegraph for three reasons: "(1) No skilled operator is required, but direct communication may be had by speech without the intervention of a third person. "(2) The communication is much more rapid, the average number of words transmitted in a minute by the Morse sounder being from fifteen to twenty, by telephone from one to two hundred. "(3) No expense is required, either for its operation or repair. It needs no battery and has no complicated machinery. It is unsurpassed for economy and simplicity." The only telephone line in the world at this time was between the Williams' workshop in Boston and the home of Mr. Williams in Somerville. But in May, 1877, a young man named E. T. Holmes, who was running a burglar-alarm business in Boston, proposed that a few telephones be linked to his wires. He was a friend and customer of Williams, and suggested this plan half in jest and half in earnest. Hubbard was quick to seize this opportunity, and at once lent Holmes a dozen telephones. Without asking permission, Holmes went into six banks and nailed up a telephone in each. Five bankers made no protest, but the sixth indignantly ordered "that playtoy" to be taken out. The other five telephones could be connected by a switch in Holmes's office, and thus was born the first tiny and crude Telephone Exchange. Here it ran for several weeks as a telephone system by day and a burglar-alarm by night. No money was paid by the bankers. The service was given to them as an exhibition and an advertisement. The little shelf with its five telephones was no more like the marvellous exchanges of to-day than a canoe is like a Cunarder, but it was unquestionably the first place where several telephone wires came together and could be united.
