Cane Sugar. — As mentioned in my last report, tests had 

 been made over two seasons of the experimental error which 

 is involved when a " sample ' of cane is taken from a 

 field or plot of this crop. Dr. Walker, the Director General 

 of Observatories, very kindly examined the results which I 

 had obtained, and acting on suggestions which he made 

 to me, a third series of tests were carried out during the 

 past season. These resulted in more definite information 

 and showed clearly what the probable error is when the 

 sample is taken by certain methods. The matter has been 

 put together for publication as a Memoir and is now in the 

 press. 



Sugar Beet. — Reference was made in my last annual 

 report to the fact that some very good specimens of sugar 

 beet had been grown at Peshawar by Mr. Robertson Brown, 

 the Superintendent of Farms. This year I took apparatus 

 to Peshawar and tested the fresh roots, which is naturally 

 more satisfactory than testing them at Pusa after a long 

 railway journey. A considerable number of individual 

 roots were tested, as also average samples of 100 roots each 

 from each field. A good deal of variation in size and quality 

 was met with among individual roots, the percentage of 

 sucrose varying from 9-0 to 20-0. The average samples 

 tested 15-8 per cent, and 15-3 per cent, sucrose respectively, 

 thus showing conclusively that this crop can be successfully 

 cultivated in that part of India. The above percentage of 

 sugar is materially better than some of the initial crops 

 which were raised in San Francisco when the industry was 

 first started there. I understand that the experiments will 

 be extended considerably during the present year. There 

 can be no doubt that this crop possesses great potentialities.
