76 SILK GROWER'S GUIDE.

 gree of attention which is bestowed on them. 



In a regulated temperature, or such a temperature 

 as Count Dandolo has prescribed, and where the 

 heat indicated by the thermometer is gradually reduced 

 from 75 deg. on the first day to 68 deg. on the 

 last, though the weather is constantly growing warmer : 

 in a temperature thus regulated, their various changes 

 or moultings usually occur on the 5th, 9th, 15th and 

 22d days, and they usually will quit feeding on the 32d 

 day. But in warm climates, as I have shown, the vari- 

 ous mutations or changes are hastened ; but it seems 

 agreed, that the amount of food consumed is the same. 

 It is evident that the Diary, which I shall omit, is only 

 for the regulated temperature. 



SECTION XXVIII. 

 FEEDING, CARE AND ATTENTION.

 by the natural warmth of the atmosphere, are removed 

 to papers placed on the hurdles. They are of a black 

 color, one twelfth of an inch in length ; those of a red 

 color may be thrown away. Feed with but a small quan- 

 tity of the young leaves or branches at a time : these leaves 

 may be torn, as the worms eat them with less waste : 

 feed them four times during the twenty-four hours. 

 When the young brood are piled too close, a part may 

 be removed on the young twigs or branches. They eat 

 well for about three days, when they grow torpid, and 

 must not be disturbed till they awake. You need not 

 remove the litter during this stage ; but during the two 

 following stages, remove the litter to a table in an apart- 

 ment separate, and strew over a few leaves, and you will
