AS TO SPACE.
The school-boy is told that the idea held by people generally in the days of Columbus was that if the venturesome ships were to sail too far out on the ocean they would fall off into space; and in his silent meditations he often wonders where, in such a case, those ships would have gone. The natural answer to his mind is that they would have gone down; but when he learns later that the words "down" and "up" relate only to the earth, and that in speaking of space, there are no such terms as up or down, or east or west, or north or south, all his ideas of direction are at sea. His conception of space increases, however.
