Other Varieties. All the above sorts are in the arboretum of Messrs.
Loddiges ; but in the catalogues of foreign nurserymen there are several
•>tiier names, most of which will be found enumerated and described in our
1st edition, including M . constantinopolitàna Poir. (M . byzantina Sieb.),
which we believe to be nothing more than a rather distinct variety of M . álba.

The white mulberry is readily distinguished from the black, even in winter,
by its more numerous, slender, upright-growing, and white-barked shoots. It
is a tree of much more rapid growth than M. nigra, and its leaves are not
only less rough and more succulent, but tiiey contain more of the glutinous
milky substance resembling caoutchouc, which gives tenacity to the silk produced
by the worms fed on them. The rate of gi*owth of young plants is
much more rapid than that of M . nigra ; plants cut down producing shoots
4 or 5 feet long in one season ; the tree attaining the height of 20 ft. in five
or six years ; and, when full grown, reaching to 30 or 40 feet. Its duration
is not so great as that of M . nigra. The white mulberry is more tender than
il-iòrus nigra, and requires more care in choosing a situation for it. Calcareous
soil is said to produce the best silk ; and humid situations, or where the
roots of the tree can have access to water, the worst. A gravelly or sandy
loam is very suitable ; and trees grown on hilly surfaces, and poor soils, always
produce superior silk to those grown in valleys, and in rich soils. The tree is
propagated by seeds (sown as soon as they are gathered), cuttings, layers,
and grafting.
