manned by men fronj Bengal and Madras, where five or six of the former expired 
from the effects of the sun, while the Madras establishment lost only one officer 
from a similar cause, It has also been stated, that although the European constitu- 
tion may bear the climate for a time, yet it suffers in the end, as has been instanc- 
ed in the campaigns of Lord Lake and the Marquis of Hastings, during which few 
Europeans died of diseases attributed to the climate, while afterwards deaths were 
frequent, supposed to have been influenced by the previous exposure. 
The produce of the country has been much underrated ; I beg leave to offer the 
following table of a comparison of a number of crops of Wheat and Barley of this 
part of the country, in various seasons, with tbe average produce of Ireland.

Jt is a fact that nothing has yet been done to elucidate the resources of the coun- 
try in agricultural matters ; anew turn, however, seems to be taken by Government 
and the public, which if persisted in must be of great advantage to the interests of 
both, and I trust we shall no longer hear of such mirthful stories as that of a 
European affirming the impossibility of raising hops in India, from a failure he ex- 
perienced himself, although he took every care, and used, as seed, the best hops that 
could be procured out of the dregs of a butt of Hodgson’s superior Pale Ale ! ! Ri- 
diculous enough, Mr. Editor, but I am afraid the jest still lies in its being applicable 
to the want of practical men. Fit fabric ando fabr.

On a Cheap Substitute for the Safty Tube of Welter. 
In a country where the price, and often the mpossibility of procuring chemical 
apparatus and re-agents is next to a prohibition on the pursuit, whatever tends to 
simplify apparatus is doubly advantageous. The following contrivance will in all 
common cases supply the place of a Welter’s tube, and has been found even steam- 
tight under considerable pressure.

1. Grind the end of a piece of quill-tube, 
an inch long, perfectly smooth. 
2. Cut a small piece of bladder, in the 
shape of «, of which the round partjis of 
tbe size of the tube, and soak it in wa- 
ter. 
3. Tie this, wet, on the ground end of the 
tube, with a waxed silken thread, and 
try it with the mouth ; if properly done, 
it will be a perfect valve while wet. 
4. Bend and draw out a piece of tube 
(large enough to admit the quill-tube 
with the valve, so that the bladder does 
not touch its sides) in the form b ; make 
it of any convenient length, — say seven 
inches in all, — leave a small orifice at 
the point. 
5. Insert the valve-tube at the top of this, 
closing the space between the two with a ; 
good cap-cement, but leaving the valve- 
tube open, as in c. 
6. Dry the bladder which forms the valve, 
and put the point of b through the cork 
where it is to serve ; b may, of course, 
he strait if required ; when on the point 
of using it, put a few drops of olive oil 
in at the top of the valve-tube: this will forced tliroiurh 
render it perfectly flexible and tight, and tfee oi w i* ’ • f t ^ e * w0 t u b e s, • 
the valve will, by being retained about it by tto capillary actwn of tbe two tube*. . 
protect it from the action of corrosive vapours
