In A. D. 1890 there was exported from China 

 alone about 21,123,600 pounds of silk. Double 

 this amount would be 42,247,200 pounds. This 

 would allow a fraction more than two ounces of 

 silk to each of the 300,000,000 inhabitants of the 

 Celestial Empire. 



REARING SILKWORMS IN CHINA. 



The Chinese have ten general rules for the 

 rearing of silkworms. 



1. The eggs while on paper must be kept cool. 



2. When the worms hatch out, they must be 

 kept warm. 



3. When molting, they must be left without 

 food. 



4. During the intervals between the molts, 

 they must be well supplied with food. 



5. They must not be placed too close together, 

 nor too far apart. 



6. During their sleeps they should be kept 

 dark and warm; after they have cast their 

 skins, cool, with plenty of light. 



8. For a little time after molting they should 

 be sparsely fed. When they are full grown, they 

 should never be without fresh food. 



9. Their eggs should be laid close together, 

 but not heaped upon one another. 



10. Wet, withered, or dusty leaves should 

 never be given to silkworms in any age.
