large portion of this must be placed to the account of labour, 
still half, or more, remains to that of the raw article, and he 
speculates on the benefit that would arise should Germany 
produce the quantity of the raw article which he is sanguine 
enough to anticipate. Prussia would no longer be compelled 
to send so considerable an amount of its coin across the water, 
— it would remain at home. A domestic production would 
compete with and supersede cotton in part, with no detri- 
ment to the manufacturing interest ; on the contrary, the 
existing cotton factories — the manufacturing machinery 
in which might readily be adapted to suit the exigencies of 
the new manufacture — would receive a fresh impulse, the 
processes being so comparatively easy, and the consumption 
of the fabrics being continually on the increase, and in these 
benefits he seems confident that the whole of Western 
Europe would also partake. 
*** The following statistical calculation is curious, if not important : — 
It is computed that 16 yards of Gros-de-Naples, of ordinary quality, or 34 
yards of a superior description, are manufactured out of lib. of reeled Silk, 
to produce which 121bs. of cocoons are required. The average weight of 
a cocoon is from 3 grains to 3 J grains ; its average length when reeled off 
about 300 yards. Taking the Silk consumed in the United Kingdom 
annually at 5,000,0001bs., the following are the statistics of production : — 
Eaw Silk 5,000,0001bs. 
121bs. of Cocoons to lib. of Raw Silk 60,000,0001bs. 
30,000 Worms to lib. of Cocoons 1,800,000,000,000 Worms. 
loz. of Eggs to 1001b. of Cocoons 600,000 oz. of Eggs. 
161b. of Leaves to lib. of Cocoons 96,000,0001bs. of Leaves. 
1001b. of Leaves from each Tree 9,600,000 Trees.
