perch, would produce 150 setiers, which, at 16 francs 
each, would amount to 2,400 francs. The annual 
product of the mulberry-trees, or that which in a 
few years they will produce, will be equivalent, as 
before stated, to 7501bs. of cocoons to the share of 
the proprietor. 
To obtain these cocoons, the space of land required 
will be 2^ perches. The value of the cocoons, calculated 
at only two francs per pound, will come to 1,500 
francs ; it is therefore clear that this sum is not only 
equivalent to the value of 2 J-, but to that of 83 perches 
of ground, ivhich would each yield three cartes of 
wheat ; in other words, the proprietor, by adding 2,000 
francs to his capital, will obtain a rent equal to that 
yielded by 83 perches of good land, which would cost 
him infinitely more. 
In fixing 200 perches for 1,000 plants of mul- 
berry, I have doubtless fixed ground enough, for in 
dry soil of 1,400 feet I have planted above 700 that 
are no wise injurious, and I have besides a high mul- 
berry hedge, which produces a great deal. 
Having thus concluded all that regards the pro- 
prietor, let us now' turn to the cultivator or tenant, 
who divides the cocoons with him. 
I will begin by one fact, which comprises thou- 
sands, and which alone can fully display all the others. 
In the year 1814, for instance, when most cocoon-crops 
failed, one of my tenauts gathered 180 lbs. of cocoons 
for his share, which was the half of 360 lbs. which 
four ounces of eggs produced. This tenant had only 
120 perches of land.
