SPACE REQUIRED FOR SILK WORMS. 



It is calculated that the worms proceeding from one 

 ounce of eggs, which in numbers are estimated at 35 to 

 40,000, should have a space on the shelves, 



As a general rule they ought not touch one another. 



QUANTITIES OF SILK YIELDED BY VARIOUS PARCELS 

 OF COCOONS. 



Eight pounds of cocoons (16 ozs. to the pound,) pro- 

 duced from 16 to 18 ounces of silk, 6 to 9 cocoons to 

 the thread. Mrs Williams obtained nearly one ounce 

 and a half, from 244 cocoons. 



Miss Rhodes had on an average one ounce from 244 

 cocoons. 



The estimates of the number of worms to make a 

 pound of spun silk are various. 



Mr Storrs, of Conn, says 4000 ; Mr Tufts, of Dudley, 

 3000 ; Mr D'Homergue says 2400, of 350 to a pound, 

 the moth not stifled. 



I should say the last estimate was the most correct, and 

 even a less number will produce a pound if they are well 

 taken care of. I have had three pounds from 8000 in 

 one season including floss.
