WATER.
It is difficult to realize that nearly three-fourths of the surface of
the earth is water; yet it is a fact.
Think of the immense space covered by oceans, seas, lakes, and rivers,
and how useful all this water is to mankind.
Sailing ships and steam-ships traverse the oceans and lakes. Steam-boats
ply along the rivers, carrying people and merchandise to and fro, going
sometimes as far as three thousand miles from their starting point.
It is by water that men float their rafts of logs or lumber to distant
places. Water turns the great wheels of many of our mills, and thus
harnessed to mighty machines, does more work than thousands of men and
horses.
These machines produce paper, cloth, flour, lumber, and many other
useful articles.
When water is heated and turned into steam, it moves powerful engines.
