From 1902 to 1907 we were engaged in making a prelimin- 

 ary survey of the races of jute cultivated in India, and, in the 

 Agricultural Ledger No. 6 of 1907, we gave an account of our 

 results to that date. We had under observation, from year to 

 year, during this investigation, plots representing practically all* 

 the races recognized b)' the ryots in every part of the two Bengals. 

 These plots were both on the Burdwan Experimental Farm and 

 at the Pusa Research Institute ; and in several j'ears the}' were 

 over one hundred in number. Red races and green ones stood 

 side by side : but the races seemed to reproduce true, after we 

 had weeded out from them the aberrant plants, which sprang 

 from the original, and often very impure, seed which we obtained 

 from the districts. 



As a result of our preliminary survey we kept apart thirty- 

 three races of Corcliorus cajjsularis, including three grown only 



* A new variety, C. cajisularis, var. oocarpiis, was discovered by us in 1910 (Jour. Asiatic 

 Society, Bengal, N. 8. VII, litll, p. Ki.j) ; but no new races of iiue O. cajisularis liave since 

 been met with.
