PROPERTILS AND VALUE OF SUNN. 287 
West India, for ordinary use. The cultivation may be much 
increased, and it is probable with considerable addition to the: 
strength and flexibility of the fibre, by the aid of irrigation; 
and this is easily managed in some, and will be so in most places 
when the great Ganges Canal is in active operation. It will 
be found there, as elsewhere, that, as stated by Mr. Deneef as 
his declared opinion, nothing is wanted but an improved 
preparation to make it a desirable article for the English market. 
Enough has been said respecting the value of common Sunn 
for most of the ordinary purposes of cordage, and also of the 
invaluable properties of the fibre of the same plant as grown 
in the Western ghauts, and where its culture may be indefi-. 
nitely extended, and easily exported by sea. ‘Though some 
recent Sunn broke with 150 lb., and some old Sunn bore 170 Ib., 
when Petersburgh broke with 160 lb., the two former may riot 
be able to bear the same degree of twisting as the latter, but 
see the experiments at pp. 268, 289. 
Brown Hemp has, by competent judges, been considered equal 
to many of the purposes of Petersburgh Hemp ; and the Wuckoo 
nar bore 175 ]b. in the same experiments. Dr. Roxburgh 
made and published a very valuable set of experiments on 
Sunn, as grown in Bengal. (v. Table, p. 268.) In Dr. Wight’s 
recent experiments, the Janapa or Sunn bore 407 Ib., and 
Cotton ropes 346 lb.; but the Ambaree or Hibiscus canna- 
binus, 290 lb., and Coin, 2241b. The Janapa, or Madras Hemp, 
a8 it is illed in the markets here, is thus mentioned by Mr. 
“Dickson, as already quoted at p 183.

“This Hemp, when prepared with the Patent Liquid, became 
soft, white, and so fine when heckled, as to bear the closest 
comparison with Flax at £80 per ton. It is better than any 
Russian Flax for fine spinning.
