SILK WORMS' APARTMENT. 87

not extinguish, in the silk room, paper matches, such as 

 emit a great deal of smoke. 



When the worms are newly hatched they fear the dust 

 made in sweeping. They are disturbed by crying and 

 weeping ; they do not like persons to come in their apart- , 

 ments, who are not perfectly clean. For example : A wo- 

 man who has been brought to bed less than thirty days, or 

 who has her menses. 



(That observation is drawn from another work upon the 

 same subject.) 



SAME WORK. 



Whenever the silk worms are raised in Autumn, the time 

 of their hatching is not distant from the three periods called 

 San-fo. (They fall in the middle of Summer.) The heat 

 (of the Summer) yet subsists, and as it occasions a great 

 deal of dampness in the apartments of silk worms, the ne- 

 cessary measures must be taken for the air to circulate free- 

 ly in every part of the nursery.
