we have shewn a siuivll amount of chance crossing to be possible, 

 are reasonable evidence in favour of tracing, to chance hybridiza 

 tion, the origin of the intermediate coloured races of jute in 

 common cultivation. 



(4). Self-fertilization is, nevertheless, the rule in the 

 species ; and, while chance crossing probably' does take place to a 

 small extent, it is not likely to exceed 2 per cent, (i.e., about 98 

 l)er cent, of the plants would tend to breed true), under the most 

 tavourable condition.'^ for the production of cress-bred plants. 

 Indeed, there is evidence to shew that, in ordinary circumstances, 

 the amount of chance crossing may not be much greater than 

 2 per cent. 



(5). It would appear therefore that, in carrying out 

 breeding experiments with jute, there is little need for elaborate 

 precaution to prevent cross-pollination ; and that no more than 

 ordinary care would be necessary to preserve a superior race of 

 jute from contamination by adjacent inferior crops
