SILK-WORMS.

remain until their third moulting unless it is in- 
tended they should be reared in the stove-room. 
If I propose a different room for the rearing of 
these insects, until their third moulting, it is be- 
cause I found it both more convenient, and more 
advantageous. 
When they are about to be removed from 
the stove-room, three circumstances must be 
noted, relative to the manner of transporting 
them. 
In the first place, whether the silk-worms are 
to be reared in the same house in which they 
have been hatched. 
Secondly, if part of them are to be reared in 
the house, and the rest removed. 
And lastly, if all are to be removed. 
1 . Let us suppose all the worms are to be 
reared in the same place. 
When the little twigs, spread over the perfo- 
thc silk-worm in its adult stages hereafter. These conside- 
rations must strongly impress the necessity of delaying the 
hatching of the eggs by some days, rather than hurry their 
coining forth ; particularly as there is no fear, when worms 
are reared in this secure manner, of their being injured ; 
should there occur two or three hot days, these would only 
accelerate the moulting a few days sooner. It is also certain 
that the later silk-worms, in their last stage of progress, 
make choice of the leaves suitable to their age, and particu- 
larly those leaves which are quite ripened, which, for the 
proprietor's interest, is the most important period, as it is at 
that last period the greatest consumption of the leaves occurs.
