maturity, starch and sugar being formed more freely at the 

 latest stage of their growth. High manuring increases not 

 only the bulk of a crop, but also the relative proportions of 

 water, ash and nitrogen, but there is a smaller proportion of 

 albuminoid matter and of carbohydrates in highly manured 

 crops. The difference in the sugar-producing capacity of two 

 lots of sugar-cane, one highly manured and the otherinot ma- 

 nured at all and very indifferently irrigated, was lately tested 

 in the Cossipore Sugar Factory. The figures obtained were- 

 from 104 maunds of poorly grown sugar-cane which were 

 crushed after topping, were obtained 11 maunds and 21 seers 

 of clean /. <?., clarified gnr ; 28 seers of filter-mud and 4 seers 

 of scum. From 23 maunds and 37 seers of well grown canes 

 were obtained 17 maunds 7 seers of juice, which yielded 4 

 maunds and 2 seers of clean gur } 13 seers of filter-mud, and 2 

 seers of scum. Thus the proportion of gur obtained in the one

1.091. In hay, straw, green-fodder and root-crops, the 

 nitrogen present is no guide to the amount of albuminoids. 

 The fat in these substances also contains a good proportion of 

 indigestible wax, and some portions of the carbohydrates also 

 have no feeding value. Weight for weight these constituents 

 in grains are better digested than in fodders. 



1.092. No experiments have been conducted on Indian 

 animals to test the digestibility of the constituents of the vari- 

 ous food-stuffs, and we must at present rely on^ European and 

 American experience in the matter. 



1,093 Digestibility has been found affected by the follow- 

 ing circumstances ; (i) Kind of animal, whether ruminant or 

 not; (2) quality of food; (3) mixture adopted; (4) age of the 

 plant used for fodder; (51 the state in which the food is given,
