Mr. Delahigarre on Silk Wormi, i^^ 



In order to get the worms out, you mud fpread over feme 

 frefh leaves, upon which they Avill get foon, fo as to enable 

 you to lift them up from the flielf. 



You mufl obferve to proportion your fhelves to the increafe 

 of the worms : for inflance, after the firfl moulting, thofe 

 who were contained in one llielf, mufl be divided in two fhelves 

 of the fame dimenfions, in order that they fhould have 

 fufficient room. The fame attention is necefTary for their 

 progreflive growth at every other moulting. 



(17th Que.) When the firll moulting is over, how may 

 we diftinguifh the worms that will do well, from thofe that 

 will not fucceed, and are likely to perifh before they pafs 

 through the other moultings ? Out of the four moultings, 

 which is the mofl dangerous ? 



(Ans.) As foon as the worms come out, you may remark 

 three different kinds, fome of a reddifli, fome of an afh, and 

 fome of a black hue. The reddifh colour is reckoned the 

 worft, that kind of worm will never do well, and we know 

 from unqueflionable experience, that it is better to throw * 

 them away : the two other kinds will fucceed and fpin the 

 beft filk. 



As to the mofl dangerous moulting, it has been reckoned 



always, that a greater number of worms perifh in the third ; 



no reafon can be afTigned for it j the fa<^ lays open to our 



Aa
