By 1896, when the Common Battery system created a new era, the telephone engineer had pretty well mastered his simpler troubles. He was able to handle his wires, no matter how many. By this time, too, the public was ready for the telephone. A new generation had grown up, without the prejudices of its fathers. People had grown away from the telegraphic habit of thought, which was that wire communications were expensive luxuries for the few. The telephone was, in fact, a new social nerve, so new and so novel that very nearly twenty years went by before it had fully grown into place, and before the social body developed the instinct of using it. Not that the difficulties of the telephone engineers were over, for they were not. They have seemed to grow more numerous and complex every year. But by 1896 enough had been done to warrant a forward movement. For the next ten-year period the keynote of telephone history was EXPANSION. Under the prevailing flat-rate plan of payment, all customers paid the same yearly price and then used their telephones as often as they pleased. This was a simple method, and the most satisfactory for small towns and farming regions. But in a great city such a plan grew to be suicidal. In New York, for instance, the price had to be raised to $240, which lifted the telephone as high above the mass of the citizens as though it were a piano or a diamond sunburst. Such a plan was strangling the business. It was shutting out the small users. It was clogging the wires with deadhead calls. It was giving some people too little service and others too much. It was a very unsatisfactory situation. How to extend the service and at the same time cheapen it to small users--that was the Gordian knot; and the man who unquestionably did most to untie it was Edward J. Hall. Mr. Hall founded the telephone business in Buffalo in 1878, and seven years afterwards became the chief of the long-distance traffic. He was then, and is to-day, one of the statesmen of the telephone. For more than thirty years he has been the "candid friend" of the business, incessantly suggesting, probing, and criticising. Keen and dispassionate, with a genius for mercilessly cutting to the marrow of a proposition, Hall has at the same time been a zealot for the improvement and extension of telephone service. It was he who set the agents free from the ball-and-chain of royalties, allowing them to pay instead a percentage of gross receipts. And it was he who "broke the jam," as a lumberman would say, by suggesting the MESSAGE RATE system.
