Supposing that to secure full success to this orchard 

 by using none of the foliage, and tilling and replacing 

 dead trees during five years, counting loss of interest 

 and other expenses accruing, we have an increase of 

 debt of $375, and a capital of $881 ; but commenc- 

 ing from the fifth year up to the twentieth of its existence, 

 the author of these statistics forms three different periods 

 of five years each. The plantation will give in the first 

 period from 90 to 95 quintals of foliage, that is, 9000 Ibs. 

 or fodder for five ounces of worm seeds ; 35 pounds of 

 silk,'about $180, that is, 20 per cent on $881. The 

 second period will annually afford for fourteen ounces, 

 15,000 quintals or 95 Ibs. of silk, equal to 47 per'cent on 

 $881. But the third period to the twentieth year of 

 age of the orchard, from 500 to 650 quintals may be 

 expected, which will feed 28 ounces and give 196 Ibs. 

 of silk, worth nearly $ 1 000, or more than 112 per cent. 



Admitting however that each crop of silk costs some 

 expense, which in no way whatever could be one quar- 

 ter or one third the profits, these latter are so secured 

 and so considerable, that the undertaking would prove 

 in the highest degree useful and profitable.
