Bihar and western Chhotanagpore. The forms with erect pods 

 occur all over Bengal ; the 2-valved subrace, however, is not 

 much grown in Bihar. The 4-valved subrace occupies west 

 Tirhut and west Bihar and extends in a southwest direction to 

 Midnapore. It is also grown in northern and north-eastern 

 Bengal. Roughly speaking, the 2-valved erect Sarson 

 is grown chiefly in Chhotanagpore, Orissa, and in west, 

 central and east Bengal ; the 4-valved erect Sarson is 

 grown chiefly in west Bihar and north Bengal ; and 

 the pendent Sarson occurs in the area to the north of the 

 Ganges beyond the region occupied by the 4-valved Sarson. 



361. Fourth, the Chittagong mustard, which is closely 

 allied to European colza. 



362. Fifth, the Nepalese mustard, which is the same 

 as the Cabbage-mustard of the Chinese cultivator. 



363. Sixth, the China cabbage which is quite distinct from 

 the last has been only lately introduced into Bengal jails. 



364. Seventh, Eruca sativa or Ta"ra"mani (Tiramira) is com- 

 monly confounded with mustard. It also belongs to the 

 natural order, Cruciferae and tribe brassiceae. The seeds are 

 compressed and light reddish brown in colour. 



365. Tori or Sorshe and Sarson or Swet sorshe are usually 

 sown with wheat or barley, or in gardens with carrots and 

 Ramdana (Amaranth), while Ra"i is usually grown by itself. 

 They are sown in September i.e., 6 weeks to 2 months before 

 the regular rabi sowings. The sowing of rdi is done earlier 

 and it is harvested in February or March, while sarson and tori 

 are sown and harvested later. There are however early and 

 late varieties of all the three crops. When tori or sarson is 

 sown with wheat or barley at the rate of ijlbs., per acre, the 

 produce is only \\ to 2 maunds per acre. Sown by itself, at 

 the rate of 4 to 6 Ibs. per acre, the produce is 4 to 6 maunds. 

 Rai is usually sown at 3 Ibs. per acre and peas are sown 

 afterwards on the same land. Grown in this way the outturn 

 per acre of rdt is 3 to 4 maunds. Grown by itself, without
