will appear, and I fliould rather choofe to 

 give up thofe worms, that were hatch'd 

 before there were leaves, for loft, and be- 

 gin a new hatching of eggs, tlian attempt 

 to feed them with any other thing than the 

 mulberry, unlefs it were for two or three 

 days, and even this, only when I could 

 procure no more eggs that feafon. 



But even the neceffity of doing this may- 

 be prevented ; for if you fear that your 

 eggs fliould hatch before the mulberiy-leaf 

 comes out, remove them into a cooler place, 

 and this will backen them for fome time. 

 Or if it is found necelTary to keep them 

 very cool in any of our colonies, in order 

 to prevent their hatching too foon ; they 

 may be put into a bottle with a pipe fix'd 

 in its neck, and then the bottle may be 

 kept under water or in a well, the mouth 

 of the pipe muft be above the water, to 

 admit frefh air, and it fliould be coated 

 well with wax, at the place where it is fix-^ 

 €d in the bottle, to prevent the entrance of 

 the water. I have tried this with a fmall 

 bottle of eggs kept in a veflel of water, 

 and it has kept them from hatching for 

 three weeks, after others had hatch'd of 

 themfelves -, yet perhaps very cold fpring
