VARIETIES OF RACES.
The different varieties OF silk worms
have been produced by demonstration,
The different climates into which it has
been carried having effected changes in
the habits OF the worm, the shape and
color OF the cocoon, or the quality OF
the silk. There are different varieties
of the silk worm the "Annual,
which produces only one crop OF silk in
year; the "Bivol,in,' or ",-crop
worm,' which like the "Annual,
matches in April OF May and which,
unlike the Annual, again matches for
second crop in eight TO twelve days
after the eggs are laid by the frs,
brood. The eggs of this sefosd brood
are always laid away for the next spring
crop; for II hatched they would no,
live, there being no food for them SC
late in the season, and the weather
being unfit To rear them. "rrivoltins
produce three annual broods, There
are also "Quadriyoltins : and, in Ben
gal, species known as "Dacey" is
said to produce eight broods in the
course OF a year Some varieties mol,
only three times instead Of four--espe
oially in warm countries--as also dc
