SILK WORMS. 121 



their food must be diminished in proportion to the degree 

 of yellow or white which their skin assumes ; the leaves 

 destined for their food, must be cut in fine shreds, and fre- 

 quently spread in light layers. 



When the silk worms are completely yellow, they ought 

 to be transported, in succession, to other hurdles, without 

 caring whether the sky be dark or serene, if it be in the 

 morning or the middle of the night. When they have been 

 transported to other hurdles, the feeding must be suspended 

 until they have all recovered from their moulting, when they 

 may be fed again. This is called diminishing the food and 

 deciding the moulting. These two expressions imply, that 

 the nourishing of the silk worms, which are disposed to 

 moult, must be diminished, (care must be taken not to cover 

 or overload them with leaves,) and, on the other side, the 

 silk w r orms must be abundantly fed, (which are not disposed 

 to moult,) in order that they may quickly moult. Not only 

 will they all moult together, but they will be exempt from 

 diseases caused by the accumulation of leaves, and the in- 

 ternal heat which consequently follows.

The silk worms may be found in ten different situations : 

 They may be cold or hot, starved or satiated, sufficiently far 

 apart, or too near together, asleep or awake ; they may eat 



slowly or with appetite.
