So while Bell, in eloquent rhapsodies, painted word-pictures of a universal telephone service to applauding audiences, Sanders and Hubbard were leasing telephones two by two, to business men who previously had been using the private lines of the Western Union Telegraph Company. This great corporation was at the time their natural and inevitable enemy.

A beam of sun or electric light, concentrated by a lens L, is reflected by a thin mirror M, and after traversing another lens L, travels to the parabolic reflector R, in the focus of which there is a selenium resistance in circuit with a battery S and two telephones T T'. Now, when a person speaks into the tube at the back of the mirror M, the light is caused to vibrate with the sounds, and a wavering beam falls on the selenium, changing its resistance to the current.

The telephone at the back of the Circuit Theater was located inside the stage-door and occupied one end of the shelf which separated Mr. Regan's hole in the wall from the entrance-hall. It was no place in which to conduct a private conversation, since any one coming or going could hear, but stage telephones are not installed for the convenience of performers.

"Tell Perry to come home for supper," was the message. That youngster slipped on his overcoat sulkily. "Wish'd there wasn't any old telephones," he snapped as he opened the door. His departure was a signal for a lull in the festivities. Mrs. DuPree sent a servant over for Sid, and the other boys followed shortly, leaving the family to watch in the darkness beside the parlor grate. Mrs.

Telephones, electric lights, street cars, and the "movies" have come to stay. The streets are cleaner. If the modern traveler finds fault with some of the conditions he encounters he must remember that many of the achievements of the people of ancient Cuzco are not yet duplicated in his own country nor have they ever been equaled in any other part of the world.

One of the most convenient inventions I saw on this planet of Ploid was the carrying of a photograph or image along a wire. The people of Ploid cannot only talk to one another many miles apart, but they can also see each other while they are talking. This wonderful attachment to their telephones, by which the human face is also carried over the wire, was perfected over one thousand years ago.

These variations, passing through the chalk cylinder produced more or less electrochemical decomposition, which in turn caused differences of adhesion between the pen and cylinder and hence gave rise to mechanical vibrations of the diaphragm by reason of which the speaker's words were reproduced. Telephones so operated repeated speaking and singing in very loud tones.

The qualities that are making them masters of the world, unfit them for slighter and less serious pursuits. The Future is for them, the kingdom of elevators, of telephones, of motor-cars, of flying-machines. Let them not idly hark back, misled by effete traditions, to the old European dream of the kingdom of heaven.

Mr. Munro can employ with all his instruments an induction coil for installations where the resistance of the line wire makes it desirable to do so; the microphone and battery being included in the primary circuit and the telephones in the secondary. Munro, in which the adjusting spring or weight is substituted by a magnet which may be either a permanent or an electro-magnet.

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.
