THE ART OF REARING 
lead them to stretch out as they grow, and pre- 
vent their getting into heaps, which is very inju- 
rious to their constitution, health, and to that 
equality in size, which it is so desirable to main- 
tain among them. 
At the beginning of this day many of the silk-

that they feel over-loaded by their covering, or

this day, the greatest number of the silk-worms 
appear torpid, and eat no more. 
Fifth Day . — This day one pound and a half of 
young leaves, chopped small, will be about suffi- 
cient. They should be scattered very lightly se-

worms have left off feeding, it would be unnecessary 
to distribute any further quantity. What I have 
said as to the different variations of quantity re- 
quired by the silk-worms of this age, is applicable 
to all the other ages. I cannot sufficiently urge
