the ground, and two and a half feet between them; at 

 one end of the shed four more shelves the height of the 

 others, thirteen feet long, one foot and eight inches wide; 

 these twelve shelves will serve for one hundred thousand 

 worms, and will consume about twentyfive hundred 

 pounds of leaves previous to their spinning cocoons, after 

 each hatching, and produce two hundred and eight pounds 

 of cocoons and make twentysix pounds of reeled silk, 

 according to Messrs Homergue's and Cobb's calculations ; 

 and by hatching the worms in succession for sixteen 

 weeks, the second hatching in fourteen days after the 

 first, and then in ten days, and then once in eight days, 

 until there is ten hatchings, which at that rate will make 

 two thousand and eighty pounds of cocoons, and two 

 hundred and sixty pounds of reeled silk, which at 'the 

 lowest price that Mr Cobb has sold his for, $4 50 per 

 . pound, amounts to $1 170, or selling the cocoons at 40 

 cents the price at Philadelphia, they would amount to 

 $832 ; or say 25 cents, the lowest price offered any- 

 where, they amount to $520. Then allowing the mis- 

 tress 820 per month, and the board of the twentyfour 

 scholars for sixteen weeks, each at $1 per week, it 

 amounts to $464, which deducted from $520, there re- 

 mains $56 ; which allowing three acres of land and the 

 trees to cost $600, the $56 will pay the interest of the 

 money and $20 left to pay interest for two sheds which 

 will be wanted if the silk is reeled ; thus you have the 

 children schooled and boarded without any expense to 

 their parents or the town, and interest on the capital in 

 the bargain. What more do you want, but faith and 

 resolution.
