ing short must be improved continually, and to the ut- 

 most ; for now they hunger incessantly, and the more 

 they eat, and the faster they feed, the more abundant 

 will be the produce of silk. During this and the for- 

 mer age, abundance of litter will collect from prunings 

 or straggling branches and the stalks of the leaves all 

 must be removed at frequent intervals, and when the 

 warmth of the atmosphere will admit, as in the former 

 ages, the numerous windows in the roof and sides must 

 be opened, to preserve a pure atmosphere. When the 

 atmosphere is damp, it must be excluded ; and the litter 

 removed the oftener, lest pestilence should ensue. If 

 you use the netting which I have described and recom- 

 mended, it may save you much labor, and will be emi- 

 nently conducive to their health. They delight in all 

 the latter stages in a cool, fresh and pure atmosphere. 

 When the weather is parching, hot and dry, sprinkle 

 the floor with water occasionally, and keep shallow 

 vessels filled with water to rectify the air. Rectify a 

 hot, moist and stagnant air by sudden flame fires. Chlo- 

 ride of lime is now the all sufficient and powerful cure 

 for a bad atmosphere. A spoonful may be placed in a 

 broad saucer, and to this five or six times its bulk of 

 water is added. These are placed in various quarters, 

 on the floor of the establishment, and replenished every 

 three days. It may be bought cheap at the apotheca- 

 ries. During every age, and until the silk-worm has 

 ceased taking food, it never inclines to wander ; a cir- 

 cumstance which has rendered this insect wonderfully 

 easy of control.
