On tlie third day, the appetite of many worms will be visibly di~ 

 minished; and, in the course of it, many will become torpid. The 

 next day, all are torpid: on the fifth, they will all have changed thei? 

 skins, and will be roused. The thermometer should range between 

 73° and 75° in the second age. 



The color of the worms in the second age, becomes a light grayj 

 the muzzle is white, and the hair is hardly to be seen. 



It must never be forgotten, that, during the time the worms are ocj 

 cupied in moulting, the food should be greatly diminished, and no 

 more given than will satisfy those which have not yet become torpid 

 on the first day, or those which have changed their skins before the 

 Gthers. 



Third Jlge. 



During this age, the thermometer must range between 71° and 73°. 

 All the worms should be roused before any are removed. The re- 

 vived worms are easily known by their new aspect. The latest worms 

 should be placed apart, as their next moulting will be a day later also; 

 or they may be put in the hottest part of the room to hasten their 

 growth. This rule must also be observed in the next moulting. In- 

 crease the spaces. 



The second day, the two first meals are to be the least copious, the 

 two last the greatest, because towards the close of the day, the worms 

 grow very hungry. The third day will require about the same quan- 

 tity as the preceding last meals; but, on the fourth day, as the appe- 

 tites of the worms sensibly diminish, not more than half of the form- 

 er feed will be required. The first meal is to be the largest: feed those, 

 which will eat at any time of the day. The fifth day still less will 

 suffice, as the greatest part are moulting. The sixth day they begin to 

 jTouse. 



Fourth Jige. 



The thermometer should range between 68° and 71°. If the 

 weather be warm, and the glass rise several degrees higher, open the 

 ventilators, exclude the sun, and make a slight blaze in the chimney, 

 to cause a circulation of the air. Widen the spaces for the worms. 

 The leaves must now be regularly chopped in a straw cutting box, 

 or with the chopping knife. The food is now to be greatly increased 

 on the second, third, and fourth days: on the fifth, less will be re- 

 quired, as, in the course of this day, many become torpid: the first 

 meal, on this day, should therefore be the largest. On the sixth, they 

 will want still less, as nearly all will be occupied in effecting their last 

 change of skin. Renew the air in the apartment by burning straw or 

 shavings in the chimney, and open the ventilators. If the evenings 

 be cool, after a hot day, admit the external air for an hour. None but 

 full grown leaves should be hereafter given to the worms; and they 

 must all be chopped. Avoid the fruit, as they would prove injurious, 

 and add greatly to the litter. On the seventh day, all the worms will 

 have roused, and thu^ finish their fourth ag;^.
