mer heat, when required. This room may
be conveniently used, also, tor killing the
chrysals IN the cocoons, as will be hereafter
shown.
Another room will be necessary for the
accommodation Of leaves, good supply Of

be provided, that no lack of supply may
occur during rainy weather. A loft over

Tor three days, but they should not be left in
compact masses, as they are apt to heat,
from spontaneous Fermentation. Ii is pro.
per that they should be occasionally stirred
and shaken about TO prevent such an event.
The fixtures Of the laboratory, are con.
venlent hurdles or shelves, for the accom-.
medallion Of the worms while feeding, and
spinning their cocoons. The best form and
construction, are those first adopted by me,
and which believe are now IN use. They
are two and half to three feet wide, and
toGr to FIVE feet long. The size may, OF
course, be varied at pleasure, without detri
ment or Inconvenience. The size men,

when ready TO spin cocoons. They are
made hike the outside frame Of window.

IS now woven in the north for the purpose
and ouly requires TO be tackled to the frame,

TO make the netting ourselves, which was
done by perforaiing the sides aud ends of the
frame with broad awl five elgh,hs of an
