221. Chain-pumps. Of the chain-pumps in use, the 

 Barrakar and the Cawnpore Pumps have found favour with 

 the Agricultural Departments of Bengal and the N.-W. P.

 which are fitted with leather washers, works better when new. 

 But the Barrakar pump being of simpler construction, is, on 

 the whole, preferable, and practically there is little difference 

 -between the two.
