The brain has been relieved of the suspense of waiting for an answer, which is a psychological gain of great importance.

It receives its reply at once and is set free to consider other matters.

A new instinct of speed has been developed, much more fully in the United States than elsewhere.

"No American goes slow," said Ian Maclaren, "if he has the chance of going fast; he does not stop to talk if he can talk walking; and he does not walk if he can ride." He is as pleased as a child with a new toy when some speed record is broken, when a pair of shoes is made in eleven minutes, when a man lays twelve hundred bricks in an hour, or when a ship crosses the Atlantic in four and a half days.

Even seconds are now counted and split up into fractions.
