The Trees
In the picture given here the tree on the left of the little house of burrs is just two stalks of the common grass called meadow muhlenbergia, which are held up as if really growing, by several green burrs left from building the house. The burrs are squeezed up tight to the grass-stems and then pressed down tight to the ground. You can find the grass for these trees almost any place; it is very social and loves to make its home with other grasses.
The graceful, drooping tree on the right of the house is made of the grass called brome-grass. Keep your eyes open and you will find it some time while playing out-of-doors. As soon as you see it, run to the brome-grass and whisper its name. You will be glad to discover it and will remember its name afterward whenever you see the grass.

Look at the picture again and notice the odd plants near the brome-grass tree. Their name is Bermuda-grass. See how they spread out their long, slender fingers. They look very much like a grass named the small crab-grass, and another the large crab-grass, and like another still called the wire-grass; but if you put all these side by side and examine them closely you will see how they differ.
