(iv) The percentage of glucose was about 1 per cent, 

 in each case. 

 (v) The coefficient of purity was found through- 

 out to vary from 80 — 90. 



(vi) The weight of roots was estimated to be about 20 



tons per acre at the time of optimum quality. 

 (vii) The roots sown February 20th were not tested 

 later than May 31st when the sucrose had risen 

 to 12-2 per cent., but they were perfectly sound 

 and growing well at the end of June. 



It is thus fairly evident that sugar-beets of good 

 manufacturing quality can be grown so as to be ready by 

 the middle of March, and by sowing on successive dates, the 

 supply could be maintained until the end of June. 



This investigation of the sugar capabilities of the 

 Peshawar Valley has thus shown that — 



(i) sugarcane can be had in the field during Decem- 

 ber and January, 

 (ii) that sugarcane may be preserved in a sound con- 

 dition in clamps over the months February and 

 March, and 

 (Hi) that a sugar-beet crop could be grown so as to 

 supply a factory from the middle of March until 

 the end of June. The factory would naturally 

 have to be fitted to deal with both crops, but 

 there should be no difficulty in arranging for 

 this and the potential length of campaign, six 

 or seven months, is unusually long. 



Production of sugar-beet seeds. — A number of roots 

 were transplanted for seed this year and some of these were 

 tested at the time of transplanting, so that if seed is 

 obtained, their progeny can be again tested and the process 

 of selection of acclimatised plants commenced. 



VII.— Milk. 



Milk of Montgomery cattle. — Between December 1911 

 and June 1912 a series of tests of the quantity and quality 

 of the milk of selected cows of the Montgomery herd at
