SILK WORMS. 



SAME WORK. 



The third day, between ten and two o'clock in the af- 

 ternoon, three hurdles, or frames, must be placed upon ano- 

 ther stage. The one above protects the worms from the 

 dust; that below protects them from dampness: and the 

 middle one is destined to receive the silk worms. Young 

 silk worms when incommoded by internal heat must be 

 changed. A small quantity of worms, occupying a space 

 as large as a square of a chequer-board, must be deposited 

 on the middle frame ; they will soon cover it entirely. By 

 degrees the quantity of food must be increased. In the 

 morning, if the weather be clear, the window situated to 

 the east can be opened, and during the day, those which are 

 in an opposite direction to the wind. By degrees they will 

 change color ; and, accordin to the color they assume, their 

 food must be increased or diminished. When they are 

 completely yellow, food must not be given them. They 

 remain motionless, and that is called theou-mien, (or the first 

 moulting.) When they have been removed after their first 

 moulting, six meals may be given them, during the space of 

 one day and night. The second day, the quantity of leaves 

 must be gradually increased. The windows can be half 

 opened. From the first moment they begin to turn yellow, 

 they must be kept very warm. When they are entirely 

 torpid they require a great deal of heat ; when they are per- 

 fectly recovered, they only want a moderate heat. 



When the silk worms are removed, after their second 

 moulting, and are all recovered, light repasts ought to be 

 given them at first. Four repasts in one day and night will 

 be enough. The next day the quantity of leaves may be 

 augmented by degrees. Some persons open the windows.
