The nearest approach to this perfect system at the present time is the multiple-board; but this has never been worked on the true or multiple principle, and it can never show all its merits until it is. The multiple-board is now being introduced into many of the largest cities, and we may expect much information during the coming year on its merits.

Now-a-days a new switchboard is often placed in service so quietly that the subscribers are rarely aware of any change taking place until after the work is completed. But in the pioneer days it was somewhat different, as is shown in the following interview clipped from an eastern paper in 1882:
