Farm gave Rs. 132, a second, Rs. 130, a third, Rs. 114, and 

 a fourth, Rs. 110. On the Gokak Farm, with the local 

 Kumpta at Rs. 120, one selection was valued at Rs. 135 and 

 another at Rs. 136. 



These results from Kumpta are valuable as they go to 

 show that a great advance can be at once effected by selec- 

 tion and that the advance even in further selection is really 

 continuous. 



By careful analysis we have realized that the Dharwar- 

 American really consists of two species, a hairy plant, the 

 true Upland Georgian, and a smooth one, the New Orleans. 

 We have also ascertained as the result of tests that the 

 former possesses qualities denied to the latter, viz., hardi- 

 ness, greater immunity from insect attack, and better cotton 

 accompanied by a higher production. Steps must be taken 

 gradually to eliminate New Orleans from the fields. A 

 sample of pure Upland Georgian was valued at Rs. 505 

 per candy while one of New Orleans at the same time was 

 valued at Rs. 490 — a difference of Rs. 15 per candy. 



Although these American cottons were introduced into 

 the district so many years ago, they have not yet become 

 thoroughfy acclimatized, and it is the practice of the people 

 who cultivate these to grow always a mixture of Kumpta 

 plants in their fields. The Dharwar-American entirely 

 fails in some years, but Kumpta is certain to give some 

 return even in the worst of seasons. The Dharwar-Ameri- 

 can matures most of its cotton in advance of Kumpta so 

 that a fair part of the former is picked pure, but an enquiry 

 is to be undertaken to find out whether the inevitable mix- 

 ture is a matter of any concern, the general idea being that 

 it is not. Anyhow as the growing of the two sorts together 

 is done to minimize the risk of loss it will be difficult to 

 persuade the farmers to give up the practice and, fortu- 

 nately, it may not be necessary to do so. 



Cambodia cotton was introduced into the district a few 

 years ago, but it is still more uncertain than Dharwar-
