from the greater ease with which an ounce can he attended to while 

 hatching, than ten ounces. This reasoning applies also to the worms 

 while feeding. 



Proportion of different qualities of cocoons, in various parcels, hc" 

 fore and after being baked. 



Tlie following facts, on this subject, are taken from the MS. .Journal 

 left by Mr. James Habersham,* on the progress of the silk culture in 

 Georgia, while a colony. 



50 lbs. of green (unbaked) cocoons produced, of the first lbs. oz.

of the second quality a little woolly - 10 04 



of dupions, or double balls, - - 12 12

18 lbs. 8 oz. of the first quality, weighed after being cured, 16 03

Cocoons weighed after being cured. 



IS lbs. S oz. of the first quality weighed - - 16 02 



5 lbs. 2 oz. second do - - - 4 06 



3 lbs. 8 oz. dupions - - - 3 00 



Mr. Habersham found, " by sundry experiments, that cocoons losfe 

 by curing, twelve per cent, in weight. They were weighed forty- 

 eight hours, or less, after being taken out of the oven. 



The following calculation of the labor attending and connected with 

 the culture of silk, in Connecticut, is by John Fitch, Esq, of Mans- 

 field, Connecticut.! 



One acre of full grown trees, set one and a half rods apart, will pro- 

 duce forty pounds of silk. 



The labor may he estimated as follows: 



For the three first weeks after the worms ai-e hatched, one woman, 

 •,v ho is accjuainted with the business, or children who would be equal 

 to such a person. 



For the next twehe or fourteen days, five hands, or what would be 

 equal to five, if performed by children. In this period, two men, 

 with other help, would be employed to better advantage, than all wo- 

 men and children. This period finishes v/iththe worms.
