What do we find in lakes? Would you not like to sail on a lake?
In the hollows among mountains are great numbers of beautiful lakes. In their clear waters may be seen the mountains, the forests, and the sky, as in a looking-glass. At night the moon and stars may be seen below you as plainly as above.
Here is a picture of a pretty lake in a valley.
You see another river that lets the water out of the lake. This river we call the outlet of the lake.
Make a lake on your molding-board, or in the sand near your home. Represent its inlet and outlet.
Out in the lake is a little piece of land round which the waters play. We could not go to this land without crossing the water; the water is on all sides of it. Such a little piece of land is called an island.
Did you ever read the story of Robinson Crusoe? You will remember that he went up a hill in search of water. When he got to the top of the hill, he saw that he was on an island. How did he know?
Have you ever seen an island? What island was it? Could you sail round it? What was on every side of it? What grew on it? What is an island?
