pounds weight, worth 24 francs. One thousand 
mulberry-trees planted would be worth 2000 francs 
capital, the interest of which would be 100 francs. 
The annual loss on young mulberry plants is calcu- 
lated at three per 100, consequently the value dis- 
bursed for 30 plants is 60 francs. Therefore the pro- 
prietor should obtain

The good and most advantageous mode of culture 
requires that the mulberry-trees, when transplanted, 
should not be stripped for three years, and that the 
fourth year they should be thinned in the branches 
and pruned ; the fifth year they will produce an abun- 
dance of leaves, and may be stripped without danger. 
It is, however, more beneficial not to strip them till 
the sixth year. After this first stripping of the leaves, 
they are cultivated according to the best common 
method, which is well known. 
From what I have said, it must clearly appear 
that the proprietor loses 184 francs annually for four 
years without return. 
At the end of the sixth spring, 1000 mulberry trees 
will, on an average, yield each 12 pounds of leaves; 
therefore there would be produced 12,000 pounds of 
leaves proper for the food of silk-worms, these 
12,000 pounds of leaves should produce 855 pounds
