The Arrah canal (which is navigable), with its 

 branches the Beeheea and Doomraon canals, com- 

 mands an area of 441,500 acres under kharif and 

 rabbi crops. 



The requirements of water are taken at one cubic 

 foot per second for each 133 acres. The duty of the 

 water for irrigating purposes is arrived at in this way. 

 The irrigable square mile is considered to contain 

 250 acres, 140 being deducted for roads, tanks, vil- 

 lage sites, &c., and the remaining 250 as not requir- 

 ing simultaneous irrigation. As one acre of rice re- 

 quires 27 cubic feet of water per hour or '0075 cubic 

 feet per second, a square mile of 250 acres requires 

 1 88 cubic feet per second, fhe canal itself has four 

 principal distributaries, exclusive of the Beeheea 

 and Doomraon canals. The Beeheea canal has seven 

 distributaries, and the Doomraon canal twelve. 



The Buxar and Chansa canals command an area 

 of 309,500 acres under kharif 'and rabbi crops. 



Bhabua, already referred to as likely to suffer in 

 time of scarcity, has, including the thannahs of 

 Ramgurh and Chand, an area of 1,037 square miles, 

 containing 1,307 villages, and a population, according 

 to the census of 1872, of 294,252, giving a popula- 

 tion of 284 to the square mile. There are several 

 rivers or large nuddies that flow through the Bha- 

 bua Subdivision which might be used for irrigation
