THE ART OF REARING 
The form of the cloths on which the egtjs have 
been received is very convenient for keeping 
them. The fillets of cloth which are raised from 
the tressels are to be folded into eight doubles, 
which should form about a foot in width. 
These cloths, thus folded, are to be placed in 
fresh and tolerably dry places, the temperature 
of which, in the summer, does not much exceed 
66°, and does not descend below 32° in winter. 
If you are afraid that it should freeze in the 
place where the eggs have been placed, a ther- 
mometer must be put there, or a little water in a 
dish. If the water does not freeze, the cloths may 
be safely left there till the following month of 
March. 
During the hot season, the cloths must be oc- 
casionally looked at every 10 or 13 days. Some- 
times it happens, that when the eggs are too 
much heaped up in one part of the cloth, and 
much dirt is mixed up with them, a kind of fer- 
mentation takes place, which engenders insects 
that spoil and devour the eggs. This is to be 
remedied, and they must be folded up again. I 
liave only once found two of these insects in one 
of the cloths. 
To preserve the cloths always in fresh air, they 
must be placed on a frame of cord (Fig. 29.), which 
is attached to the vault or ceiling of a fresh and 
dry place. In this way the cloths have air on all
