obtained from the neighbourhood of Piisa, gave the following 

 results : 



Less on hydrolysis (1 hour in 1% potash) 



Celhilose 



Average lengtli of ultimate fibres 



These figures, which require further confirmation from samples 

 produced under more nearly identical conditions, indicate a con- 

 siderable superiority of .Tubbulpore hemp over local Sann, both 

 from the point of view of strength and of durability. They are 

 supported by the fact that, on being tested, the Jubbulpore hemp 

 showed markedly greater tensile strength than local Sann." 



The occurrence of two sucli distinct varieties of Sann-\\eva^ 

 in India as those described above shows the desirability of conduct- 

 ing a survey of the crop grown in the various Provinces of India. 

 Accordingly, steps have been taken to collect and grow at Piisa 

 samples of this crop from all the typical tracts in which its cultiva- 

 tion is of importance. Possibly other varieties will be found in 

 addition'to the two described in the present paper.
