the seed indiscriminately. The condition of intermixture at pres- 

 ent is : — 



At Pusa, Bh6u[ila and A si Deslii are not to be found in pure 

 crops ; tliey are often mixed in proportions of about 3 : 1, Aal 

 Desbi prevailing: 



At Dalsing Sarai, a number of crops are of Bhdgila grown 

 pure ; the others are intermixtures of varying proportions ; farther 

 one crop contained a few plants of Gajar-ganga, and another a 

 few of an American cotton : 



At Saing and Sirseah, one small crop seen, was entirely of Asl 

 Deshi, and another of Bhdgila ; the rest were mixtures of vary- 

 ing proportions, Asl Deshi generally predominating : 



At Sarai and Kutupur, Bhogila prevails in most crops, but 

 none are pure : 



At Barh, towards the south, Asl Deshi is grown almost pure, 

 but to the west Bara-isar, which is almost a snbrace of Bhdgila, 

 makes about 50 per cent, of very mixed crops ; 



At Matrapur, Asl Deshi is grown, with a very slight admix- 

 ture of Jageria, w^hich like Bara-isar is almost a subrace of 

 Bhogila. 



The plants considered to be hybiids were found at P 

 Dalsing Sarai, Saing and Barh. 



As the cultivators usually clean their own seed except near 

 the Hajipur Ginning Mill, and foi^merly did so near Hajipur, 

 the degree of admixture reached indicates a cultivation of the 

 two cottons together for some decades at the very least ; 

 and dui'ing the decades, what witVi the trifling selection ^ tliat 

 the cultivator now and then does, and owing to the smallness of 

 the amount of hybriding that, nature does, the races have des- 

 pite the intermixture maintained their purity.

history 



The extrafloral nectaries play a small part in attracting 

 insects to the flowers. It has been seen that they are resorted 

 to by insects such as Elis and Apis, wfiich have failed to reach 

 the honey within the calyx. They possibly may retain insects 

 about the plants in the early morning until the flowers open. 

 At the rare still times when there is neither an east nor a west 

 wind, they attract insects whose settling is enough to jerk the 

 flower's own pollen onto the stigma, 



Tliey attract a patrol of ants, one of which— unfortunately 

 unnnmed above — is very ready to bite any intruder ; and they 

 attract wasps which we know to be at times verv self-assertive
