THE ART OF REARING 
in the lower part of the wall they should draw 
ujj, and when in the ceiling slide down. (Fig. 10.) 
Piercing Iron . — This tool should be made 
like a stamp ; and by hammering on it, will cut 
round holes in doubled paper' placed on a block. 
Several sheets of paper may thus be stamped at 
once, which are used to put over the egg boxes, 
when the worms are just hatched. Many employ 
a thin veil, or very coarse muslin ; for this pur- 
pose, and with the same effect, it is unimportant 
which is adopted. (Fig. 11. a.and£.) 
Hook . — Small instrument made of bent iron, is 
very useful to take up neatly and quickly the 
small branches covered with silk-worms from 
the boxes, to put them on the sheets of paper 
prepared to receive them in the small laboratory. 
With this instrument, it is not necessary to touch 
the worms with the hand, and they avoid the 
risk of being crushed. (Fig. 12.) 
Travelling Case . — In this pack or box the 
hatched worms of 20 ounces may be moved to 
any distance ; it weighs about 75 pounds. It is 
divided into drawers, or shelves, and when there 
are fewer worms, some of the drawers may be 
taken out to give more space: each slide or 
drawer can hold a sheet of paper containing the 
worms of an ounce of eggs. It is the most useful 
$nd convenient method of transporting the insects 
about, (Fig. 13.)
