168 LUCY AMONG THE MOUNTAINS. “ Where does it come from, at first?” said Lucy. “Tt comes from a spring,” said her mother, “I suppose. Some springs break out of the ground from under a rock.” “© What makes the spring ?” asked Lucy. * Why, the water in the mountains above,” re- plied her mother, “presses down in among the rocks, and wherever there is a crevice in the rock near the surface of the ground, the water come$ out.” “‘ But what makes there be water in the moun- tains above?” asked Lucy. “Tt comes from rains.” “ Then I should think that, when it had done raining, it would pretty soon stop coming ‘out in the spring.” “¢ No,” said her mother ; “it takes a great while to drain off. The earth, and the moss, and the roots, and the stones, hold the water like a great sponge. It slowly soaks down, and gets into the crevices and fissures, and so runs out in a steady stream, wherever a fissure or any opening of the rock comes out to the surface. Still, if it has not rained for a very long while, the springs begin to grow low, and some of them stop running entirely.” . They staid at this place mote than an hour. After they had eaten their luncheon, they rambled about among the rocks, and along the shore, gathering flowers. Lucy amused herself in pick- ing up pebbles and throwing them into the water.
