설명 CLASS IN TELEPHONY: ENLISTED MEN, U. S. ARMY. The province of the telephone in modern warfare is constantly broadening. It is one of the agencies which has robbed battle of much of its picturesqueness, romance, and glamor; for the dashing dispatch rider on his foam-flecked steed is practically a being of the past, more antiquated than the armored knight of medieval days. A message sent by telephone annihilates space and time, whereas the dispatch rider would, in most cases, be annihilated by shrapnel.
