SILK WORMS. 1 1 1 



number of silk worms to be fed, and to calculate, in advance, 

 the quantity of leaves which will be wanted." 



SAME WORK. 



When the newly hatched worms are made to descend, 

 they must be dealt carefully with, spread upon the hurdle 

 in an equal manner, and a proper space left between them. 

 Care must be taken not to wound them, or to press one 

 against the other. As soon as the worms are all hatched, 

 the fresh and tender leaves must be taken, and cut in very 

 fine shreds, with a very sharp knife ; then they must be 

 spread, with a coarse sieve, upon the sheets which are to 

 receive the silk worms, and under which a bed of chopped 

 straw must be previously spread. The cut leaves must be 

 spread in an uniform manner, in very light layers. After- 

 wards the sheets of paper must be taken, where the worms 

 newly hatched are, and they must be applied to the mulber- 

 ry leaves ; the worms descend themselves on the mulberry 

 leaves. If some worms are too long a time in descending, 

 or if they ascend upon the back of the sheet of paper, or if 

 they do not descend, when the leaf is turned over, they must 

 be thrown away, with the leaf to which they remain attach- 

 ed. They are diseased worms, that it would be impossible 

 to raise. 



SAME WORK. 



The success in raising silk worms depends on the precau- 

 tion which is taken in the beginning, and subsequently, not 

 to expose them to any danger. If the silk worms do not 

 revive all at once, from their first sleep, or moulting, it pro- 

 ceeds from their not having changed color, and not hatching
