October. Sunday evening's milk was usually rich in fat, 

 because of the short day interval, but Monday morning's was 

 usually poorer and greater in quantity. On Thursday morn- 

 ing, September 10th, this cow produced 16 Ib milk, with 

 1*1 per cent, of fat, and on the following morning 19 Ib of 

 milk, with 6*8 per cent, of fat. The first of these was preceded 

 by a cold and wet evening, while the following was a better 

 night. Evidently, therefore, the poorer milk was caused by 

 the cow being upset by exposure during a bad night, after 

 which a big reaction followed. Tuesday, July 14th, was a hot 

 day, and that evening the cow gave rather less milk with only 

 1*8 per cent, of fat, whereas the milk of the previous evening 

 had contained 4'6 per cent, of fat. When this cow was in 

 season on June 10th, the morning's milk contained 1'5 per 

 cent, of butter fat only, although the quantity was not reduced. 



NEWTON BJGG RESULTS. 



Mixed milk. The milk of seventeen cows was tested for fat 

 once a month during one year. Milking took place at 6 a.m. 

 and 5 p.m. The following average results, which compare 

 the effects of indoor and pasture feeding, are interesting : 



Average fat in milk. 

 Morning. Evening. 



December, 1902, to April, 1903 (cows indoors) 3'8 o/ 4-2 o/ 



May to October, 1903 (cows on pasture) ... 3*5 % 3*6 % 



November, 1903 (cows indoors) 8-696 3 "1 % 



It will be seen that during the winter months the milk 

 contained much more fat, and also that the evening's milk was 

 relatively much richer, when the cows were indoors than when 

 they were on pasture. The morning's milk on September 15th 

 had just the standard amount of fat (3 per cent.). The table 

 of results shows that in all other cases it was well above the 

 standard. The solids not fat (calculated from individual 

 samples) were well over the standard during most of the year, 

 especially during the first six months. They were lowest in 

 the autumn, and were only just above the standard on the 

 evening of August 15th.
