It is the white mulberry whose leaves are the food of the silkworm. The leaves of this tree are quite regular, but those of the red and black vary apparently as they please. No two leaves seem to be alike either in size or shape, and they are very soft and downy.

The evergreen trees, so called because their needle-like leaves remain on the tree all winter, are fully as interesting as the broad-leaved trees. Without them our landscapes in winter would be much more barren and bleak, and their shade is very pleasant in summer. A pine forest with its fresh balsam air and needle-covered floor is a sight to be long remembered.
