INSTITUTE AND COLLEGE, PUSA, FOR 1911-12. 29 



cent, more than the latter; the difference was greater with 

 seme than with other cows, but no cow was an exception to 

 the rule. No systematic difference was found in the com- 

 position of the milk of the one side of the udder and the 

 other side, but a systematic difference was observed with 

 two cows in the composition of the milk of the fore quarter 

 udder and hind quarter respectively. This latter point 

 was tested with only three cows, so that whether this is a 

 common or an exceptional characteristic of the cows is not 

 yet known. The percentage of fat in the milk of this herd 

 has been about 4 to 5 per cent, in the morning and 3 to 4 

 per cent, in the evening, which is less than has been found 

 for Sind and Gir cows at Poona. 



Regarding the yield of miilk this was found to be from 

 5 to 6 lbs. per day obtained by hand, to which must be added 

 the like quantit}^ taken by the calf, making 10 to 12 lbs. or 

 say 5 to 6 seers daily which is also less than what the Sind 

 and Gir cows yield. 



13. Education. — There are at present five students in 

 this section; three of these being Government stipendiary 

 students, one each from Bengal, Bihar and Orissa and 

 Travancore; and two private students. One of the students 

 mentioned in my last report was considered not likely to 

 prove himself an efficient assistant and he was consequently 

 not permitted to complete his full course of study. One 

 student of the Entomological Section took a special course 

 of photography.
