68 THE CULTURE 



^While the filkworms are very young, 

 they take up but very little rooni, and 

 during the firft fortnight at lead, may be 

 kept in (liallow broad drawers, boxes, and 

 fuch like, and that in great numbers j for 

 a foot iquare may contain above ten or 

 twelve thoufand of thofe newly hatch'd, 

 but as they grow larger, fo muft alfo the 

 fpace that contains them. Thofe there- 

 fore who have large nurferies of filkworms, 

 fliould provide a place large enough to 

 hold them when at their greatcit fize ; a 

 foot fquare will not contain above an hun- 

 dred worms conveniently, when they are 

 full grown. 



As to the temperature of the place in 

 which they are kept, cellars and all moift 

 places are to be avoided, nothing being fo 

 great a detriment to their thriving and 

 health as moifture j high places, fuch as 

 thofe next the tiles of an houfe, are alfo to 

 be avoided, for here they would be too 

 hot in warm weather, and too much 

 chilled in cold weather ^ an equal degree 

 of heat is what beft agrees with them, and 

 that heat always from a dry and not a 

 moifl: air. The temper of the climate is 

 therefore to be regarded, fo as in hot cU-
