proved in the Punjab and United Provinces that the Up- 

 land Georgian is hardier and more resistant to insects and 

 disease than the New Orleans. Of the multitude of exotic 

 American cottons which have been tried only two of the 

 number are worth introducing. They are far superior to 

 the local article in quality, but they fail in yield as yet. 



The area under Cambodia is gradually extending. But 

 as has been said above, taking one season with another, 

 Dharwar-American is more certain, and therefore the 

 latter will continue to hold the field. 



During the last six years the special class of Cambodia 

 cotton, with a ginning percentage of 37 and over, command- 

 ed on an average Rs. 60 to Rs. 70 more per naga (naga = 

 1,344 lb.) than the ordinary Dharwar-American and the 

 lowest class, with a percentage of 335, Rs. 30 to Rs. 35 

 more. Last year, however, the difference ranged from 

 Rs. 65 to Rs. 100 per naga. 



Gujarat and Kathiawar. Here we have the last great 

 cotton area in Bombay. The prevailing species is Gossy- 

 pium herbaceum of Todaro, the varieties of which are 

 usually restricted each to a certain class of soil. On the 

 whole the distinctions are only dimly appreciable in the 

 external characters of the plants but they are easily detected 

 in the lint, so that it is only when the crop is ripe that the 

 varieties can be readily distinguished. 



Starting from the southward as far north as the Tapti, 

 we have the Navasari strain, which is accepted as the best 

 cotton in India. The good soil, genial climate and proxi- 

 mity to the sea, all favourably influence the quality of this 

 cotton. 



Further north, about as far as the Narbada, there is the 

 Surti Broach strain, which is only slightly inferior to the 

 Navasari. 



From here, however, deterioration steadily sets in. In 

 the Broach District and adjoining parts the strain is con- 

 taminated with a high ginning, short-stapled form of un- 

 certain ancestry called ghogari, Its antecedents are doubt- 

 ful but it may be a cross between Wagad (to be mentioned
