 ON THE RAISING OF SILK WORMS. 



I lo 



EGGS OF THE SILK WORMS. 



Each chrysalis changes to a moth. After the expiration 

 of three days, it pierces the cocoon and comes out. The 

 male and female resemble each other. The female remains 

 immoveable, the male flies about in search of the female, 

 to whom he unites himself. After having been united one 

 day and a half, he quits her. As soon as the male butterfly 

 has left the female, he withers and dies. The female im- 

 mediately lays her eggs. Some persons make the females 

 lay their eggs upon paper, (made of the bark of the mul- 

 berry tree,) others on a piece of linen. Every country has 

 its customs. In the district of Kia and Hou, a thick paper 

 is made use of, manufactured of the bark of the mulberry 

 tree. The following year, the same leaves of paper may 

 be used. 



A female butterfly lays about two hundred eggs, which 

 adhere to the paper ; the eggs are distributed over the paper 

 in an equal manner, without being accumulated together.
