FUNDAMENTALS

Every life is dominated by a fundamental note, good or bad. All its

overtones will ultimately correspond.

The wires strung from pole to pole are set into oscillation

by the wind, somewhat as the strings of a violin are set into

vibration by the bow. In skilful hands the violin bow can be

made to bring forth from the string one powerful fundamental

note and several overtones of higher pitch, but in perfect

harmony with the fundamental. But the wind is a very skilful

performer, and brings forth at the same time not only the

deepest fundamental bass note of the wire, but a great variety

of overtones, both harmonious and discordant. In fact, the many

wires strung overhead, from pole to pole, constitute splendid

Eolian harps.--_Telephony._
