104 On the Management of Silk- Worms. 



kept. As soon as the mulberry-buds begin to open 

 into leaves in the spring, we should bring the sheets 

 of eggs into a warm room, and lay them in a south 

 window, where the sun may shine through the glass 

 upon them. We may, perhaps, do this several days 

 before they begin to hatch ; but, notwithstanding 

 this, when we lay them by, we should not return 

 them into a cool room. 



As soon as the worms appear, pick the small mul- 

 berry leaves from the tree, and lay them, with the 

 under sides downwards, upon the sheets of eggs, in 

 those places particularly where they have already 

 hatched ; and the worms will immediately begin to 

 eat. As the leaves fill with the worms, take them 

 up carefully, and lay them on a sheet of clean paper, 

 which should be perfectly dry, and apply fresh leaves. 

 The greater part of those worms, which hatch in a 

 day, come out before evening ; and we should be 

 cautious to keep the hatchings of every day upon se- 

 parate papers, that they may be prevented from in- 

 termixing with each other ; and, indeed, during the 

 whole time of their feeding, we should strictly adhere 

 to this caution ; for as the worms moult at certain pe- 

 riods from the time of their hatching, the sick among 

 them would be liable to communicate the infection to 

 the others, and thus create infinite trouble. 



Whenever we intend to clean them, we should, as 

 before, lay fresh leaves over them, and when they 

 have pretty generally come upon them ; remove the 

 leaves upon clean sheets of paper, and brush and dry
