It is of a pale lemon colour; and is considered more durable for trenails than any other--that of the locust excepted.
"The red mulberry, like the white and black species, runs into several varieties, differing considerably from each other.
"There is still a fourth species of this genus, called the paper mulberry (_Morus papyrifera_).

This, however, has been separated by botanists into another genus; but it is worth a word here, as it is a very curious and valuable tree, or, rather, a large shrub, for it does not grow so tall as either of the other three.

It is a native of China, Japan, and the islands of the Pacific Ocean; but, like the others, it is cultivated for ornament both in Europe and America.

Its fruit, which is of a scarlet colour, is globe-shaped, and not oblong, as that of the true mulberries; and this is one reason why it has been separated into a genus by itself.

Its leaves are of no use for silk-making, but they make excellent food for cattle; and as the tree grows rapidly, and carries such large bunches of leaves, some people have said that it would yield better than grass, and should be cultivated for pasture.
