pounds of leaves the produce of one acre would feed 

 3,600,000 worms, and cost for feeding them, $705, which 

 being deducted from $1,875, the price of the produce, 

 leaves $1,170 for the annual income of one acre of trees. 

 Thus, by the above calculations, differing but little in the 

 amount, it is seen that the income afforded by one acre, 

 after seven years, must be immense. This acre, it is to 

 be presumed, must be of the best quality, and the trees 

 highly cultivated, to produce so much. Mulberry trees 

 will grow on poor land, but the produce will be compara- 

 tively small. But supposing Mr Homergue's calculations 

 to be made from the best kind of land, and that we have 

 much poor, rocky land, let us call the product of leaves 

 only one-tenth as much as is estimated above, we have 

 only three pounds of leaves from each tree, and lest it may 

 require more help to feed the worms, we will say four 

 women and twelve children, which will reduce the 

 cocoons to 750 pounds, and the sales to $187 50, and the 

 cost of feeding will be $141, and there will then remain 

 $46 50 for the annual income of one acre. 



All the uncertainty in these calculations, arises from 

 the quantity of leaves produced on an acre, and that must 

 vary according to the quality and cultivation of the soil ; 

 all the rest can be ascertained from actual experiment. 

 But I understand it is the practice of some to let their 

 trees on shares one fourth of the cocoons to those who 

 gather the leaves, one-half to those who tend and feed 

 the worms, and the other fourth to the owner of the trees, 

 which, if the trees produced 90,000 pounds of leaves, and 

 the cocoons sold for $ 1 ,875, would be for one half, $937 50, 

 and one fourth $468 75. But supposing the trees to pro-
