feed ; and as they approach the period of rising, 
their excrements are nearly of the taste and colour 
of the natural leaf, which proves that it has 
hardly been decomposed in their bodies. 
It also happens that many worms, too full of 
food, afterwards require a day or more to evacu- 
ate it, and shew signs of uneasiness before they 
become empty, evidently proving that the func- 
tions of the stomach and intestines are consider 
ably weakened. 
4. Cleaning of the Hurdles ; end of the Prepa- 
rations for the rising of the Silk-worm. 
As soon as the worms are prepared to rise, the 
hurdles should be cleaned thoroughly. This 
operation, although tedious, is easy enough, with 
the aid of the r portable traj^s. These portable 
trays cannot now be put on the hurdles, because 
tue fagots placed round them prevent it ; how- 
ever, they may be supported against the trays, so 
as to be able to use them within. When they are 
placed near the trays, the silk-worms must be 
carefully put upon them. Two or three port- 
able trays should be filled. This done, the litter- 
should be emptied from the sheets of paper into 
the square baskets. 
When one portion of the hurdles have been 
cleaned, the paper is replaced, and the worms 
gently slided down upon it by slanting the tray.
