Service All the Way An Advertisement of the American Telephone and Telegraph Company IT Is impossible for a railroad ( train or a ship to call at the doorsteps of its passengers when they wish to take a journey. To take even a trolley or bus ride, one must go to some definite point where the conveyance stops. On the other hand, the telephone goes all the way to meet the public's convenience. Each telephone call may be com pared to a taxicab, whose destination is controlled by the subscriber. The telephone company extends its wires to the homes and offices of those who desire service, placing its telephones within immediate reach. The call is made at the time, from the point, IEl and to the place that the sub scriber desires. He speaks to the person he wants-wher ever he may be. At the disposal of each telephone subscriber are the talking channels of the entire Bell System. He may make a call a few or thousands of miles, and he may extend his voice to any point, to any person who has a telephone. This is the essence of communica tion. Because of it, the number of tele phones has increased in the last five years three times as fast as population. Because of it, the Bell System carries more than twenty billion messages in the course of a year.
