Mr. Dclahigarre on Silk IVonns, ig^ 



(Ans.) From the fymptoms given in our 27th query^ when 

 you know that your worms are mature, you prdent them your 

 finger, to which they readily attach themfelves ; but as it 

 would be too long and tedious to carry them ail one after 

 the other, you depolite as many as you can upon a varniflied 

 plate, to which they cannot ftick fafl, and you carry them 

 all at once upon a bough-table. It will be eafy to diftinguifh 

 thofe who want to be fed yet ; becaufe they lay on the table, 

 and refufe to get up on the bough. 



(30th (^E.) How many days does the filk worm employ 

 in the fpinning, and what is the time to pick up the cocoon ? 



(Ans.) The worm's fpinning is completed in three or four 

 days ; but as among a great number, they do not fpin all at 

 the fame time — the beft method is to pick up the cocoons 

 twelve days after the firft worms have begun their fpinning. 



(3 1 ft Que.) Is it neceflary to kill the worms in their cocoons ? 

 "When and how ? 



(Axs.) If you cannot draw the filk foon after the picking 



up of cocoons, it is indifpenfible to choak the chryfalis 



contained in each cocoon, otherwife that chryfalis would foon 



become a butterfly, and by boring its way through the cocoon, 



break the contexture of the filk. Therefore, after you have 



chofen and fet apart the beft cocoons intended for eggs or feed, 



as mentioned in the 4th query, vou muft take off" the upper
