How Fast the Earth Moves.

Most persons are aware that the earth makes a complete revolution on its axis once in twenty-four hours, but probably many are Ignorant as to the high rate of speed in accomplishing the feat. The highest velocity ever attained by a cannon-ball has been estimated something like I.GOO feet per second; and the earth must turn almost equally fast. In short, the rate of speed at the equator has been estimated at nearly 1,500 feet per second, or a mile every 3.0 seconds, or 17 miles a minute.
