SILK-WORMS.

It should contain all the necessary implements 
that may be wanted ; I may be thought too mi- 
nute in the following details, but this shall not 
deter me from giving every explanation I may 
deem requisite in so important an art. 
This small apartment should contain — 
1st. A stove of a moderate size, not made of 
iron, because the heat could not be regulated so 
accurately, but of thin bricks ; it must stand out 
in the room ; it is calculated to raise, by de- 
grees, slowly, and at will, with little wood, the 
temperature of the room (Fig. 5.) 
2d. Several boxes or trays, either made of 
thick paste-board, if they are not large, but if 
large, of thin boards (Fig. 6.) 
The size of these boxes should vary according 
to the quantity of eggs which are to be hatched ; 
for an ounce of eggs the space of about eight 
inches square are required. This may give an 
idea of the size and number of boxes that may 
be wanted, and we shall see hereafter how useful 
it is not to depart from this rule. If there are 
more than six ounces of eggs to be hatched, the 
box should be of thin board. Pasteboard boxes 
should be about half an inch deep. The depth 
of the wooden trays or boxes must, of course, be 
proportionate to their size. The boxes should all 
be distinctly numbered. 
3d. Some wicker trays or tables (Fig. 7.)
