tan. Morus Tatarica, L., resembles M. alba, Its 
juicy fruit is insipid and small. The leaves are not 
generally used for silkworms. 
The results of Mr. Brady’s experience on the vari- 
eties of the Morus alba are as follows: In the nor- 
mal form the fruits are white, with a purplish tinge 
- more or less deep; the bark is pale; the leaf is also 
of a pale hue, not very early, nor very tender, nor 
very abundant. It may be grown on moist ground 
as long as such is drained, or it will live even on poor, 
loose gravelly soil, bordering on running water. The 
Cevennes variety is a free grower—affords a large 
quantity of leaves, though of rather thick consistence ; 
all varieties of the Morus Bombyx like these leave 
at all stages of their age. It is also called the rose- 
leaved variety. The silk which it yields is substan- 
tial in quantity, and also good in quality. It does 
best on rich, dry slopes. The bushy Indian variety 
has a fine leaf of beautiful green, which, though light 
in weight, is abundantly produced. It can be cut 
back to the stem three or four times a year. The 
leaves are flat, long, and pointed, possess a fine aro- 
ma, and are relished by every variety of the ordinary 
silk-insect, though not all thrive equally well on it. 
The silk derived from this variety is excellent, but 
not always so heavy in quantity as that produced 
from the rosy variety. It prefers rich, low-lying bot- 
toms, is a greedy feeder, but may thus be made to 
cover an extraordinary breadth of alluvial or manured 
land in a marvellous short space of time. At Sydney, 
Mr. Brady can provide leaves from this Indian vari- 
ety all through the year by the removal of cuttings, 
which will strike their root almost at any season. It
