of cocoons, of which 427 lbs. 8 oz. belong to the pro- 
prietor. 
We must also consider that the income increases 
yearly, if the mulberry-trees are well cultivated ; al- 
though out of the 1,000 there would only be 750 
which can be stripped annually, 250 trees remaining 
only pruned and fallow. 
When the 750 trees are of a size to produce each 30 
pounds of leaves, they will yield altogether 22,500 lbs. 
which may produce 1,605 lbs. of cocoon, the half of 
which belong to the proprietor. 
The calculation I have just offered will be suffi- 
cient to shew to those who have the intelligence of 
business, that there exists no branch of industry 
which interferes so little with others, and yields greater 
annual profit, than the cultivation of mulberry-trees 
and silk- worms. 
Besides what I have been saying, there are four cir- 
cumstances concurring in favour of the proprietor. 
1. It is a fact, that however extensive the plantations 
of mulberry-trees may be, on land already let and 
tenanted, the proprietor generally makes no compen- 
sation or allowance to the tenant for the ground thus 
occupied. 
2. Wc have supposed the proprietor to buy all his 
mulberry-plants, and each plant to cost two francs. 
If he gets his plants from his own nursery, and al- 
though he should have the banks dug and manure 
them thoroughly, yet will not each plant stand 
him in a franc.
