3. The quantity of mulberry-plants that we have 
averaged would not die, and casualties are exag- 
gerated. 
4. If the proprietor go halves with the cultivator 
in the rearing of silk-worms, he obtains directly, or 
indirectly, the greatest share of every advantage which 
the cultivator derives from them, because the produce 
of the whole of the cocoons ends by almost all 
coming into the hands of the proprietor. 
Besides it being well known that the rent of the 
farm may be raised as the value increases. 
Such is the true state of things. Any who wish to 
detract from the value of this important art are at 
liberty to do so. I will only say, that if the proprietor 
does not attentively watch the plantation of the mul- 
berry-trees, and their culture, particularly during the 
eight or ten first years, he will not receive from 1000 
trees the quantity of leaves which an able agriculturist 
will get from 200 mulberry-trees at the end of six 
years. 
This observation deserves the strictest attention, 
because it is the basis of those lasting advantages 
which may be derived from this valuable branch of

There are further considerations which must be laid 
before the proprietors. 
Let us suppose the 732 mulberry-trees above men- 
tioned, only standards on the land (or even a thou-

planted on a surface of about 2000 feet of good ground. 
This ground producing three cartes of wheat per
