small will run the risk of being lost and carried out 

 among the litter. When the worms are in the first age, 

 you need only clean the litter once or twice, as you find 

 it necessary. During the whole of the first age, the 

 leaves of the young plants of the mulberry, as being the 

 tenderest, are preferable to the leaves of older trees for 

 the food of the young worms. It is well therefore to sow 

 some mulberry seed every year so as to have a succession 

 of young plants. During the temporary sickness produced 

 by the changing of the skin they should be fed with a 

 very sparing hand. The sign, by which it is known that 

 worms are sick and about to change their skins, are these

 sleep ; this should be noticed. 



During the second age it is advisable still to continue to 

 feed your worms with leaves from the young plants, as 

 they are still preferable for them. You must now begin 

 to be attentive to clear away the litter from time to time, 

 so as to prevent all danger from its heating, which proves 

 highly injurious, though some people never clear away 

 the litter.at all. These insects are remarkably fond of 

 cleanliness, which besides helps to enliven them and 

 gives them a keen appetite for the leaves that are given 

 them. The litter is taken away in the following manner ; 

 you scatter some fresh leaves upon one corner of the shelf, 

 to which the worms having attached themselves, which 

 they will readily do, you then take up the worms by means 

 of the leaves and stalks they cling to, leaving the litter 

 underneath. Having thus taken up all the worms from 

 that corner and placed them in a clean place, you then 

 clear away the litter from that corner and carefully sweep
