standard in the mixed milk. Two cows of a nervous tempera- 

 ment gave milk in which the fat varied considerably. Fre- 

 quently when the cows gave more milk it had more fat, and 

 when they gave less milk it had less fat. 



ALNWICK RESULTS. 



The mixed milk of three shorthorn cows was tested daily 

 at the Duke of Northumberland's Home Farm, from March 

 19th till April 20th, 1903. The three cows were from five to 

 nine years old, and calved on January 5th, February 7th, and 

 February 27th respectively. One was a pedigree and two were 

 non-pedigree animals, the latter being purchased for rearing 

 calves. They were milked at 6 a.m. and 6 p.m. They gave 

 on the average nearly 5 gallons of milk in the morning and 

 about 4 gallons in the evening (an average of 3 gallons a 

 cow daily), so that with equal time between milking the 

 morning quantity was greatest. The morning's milk was 

 fourteen times, and the evening's milk seven times, under 

 the fat standard during thirty-three days. The fat in the 

 morning's milk varied from 2'15 to 4'25 per cent., and in the 

 evening's from 2'45 to 4'35 per cent. 



Effects of weather. The cows were turned out from 11 

 to 1 o'clock daily after March 24th. The milk had more fat 

 for a few days afterwards, but a reaction followed, as the 

 poorest milk was given on the last three days of March. The 

 weather was not colder, but a strong wind on March 28th and 

 29th may have upset the cows and reduced the fat in the milk. 

 The milk of each of these cows was tested on April 2nd and 

 17th. On the first morning the milk of each cow was under 

 the fat standard, one having less than 2 per cent, of fat. A 

 strong north-west wind was blowing during that and the pre- 

 vious day, which, as all the cows were affected, probably 

 reduced the fat in the milk. On April 17th the cow that had 

 previously given milk with less than 2 per cent, of fat now 

 gave the same with over 4 per cent, of fat, while the milk
