THE STRING TELEPHONE. — Mr. N. R. Huntley, an engineer of Springfield, Mass., U. S., has so far perfected the toy telephone as to talk plainly across the Connecticut river, a distance of 2,450 feet, or nearly half a mile. The boxes have thin iron diaphragms. The line is not straight but zig-zag, and is supported by iron pins fitted with glass insulators, which prevent the sound from leaking. He fully expects to make a serviceable private telephone out of this arrangement.
