the weather was very warm, and the evening's milk was very 

 slightly richer in fat than that of the morning, which may 

 be due to the effect of the heat on the cows. The cold, wet 

 night of June 17th affected the milk of cow No. 1, by greatly 

 reducing the quantity of her morning's milk, while the fat 

 percentage in the milk of cow No. 8 was reduced very largely 

 on the same morning. 



Change of food. The cows were turned out at night 

 on and after May 9th, and their milk was tested till May 12th. 

 The weather was fine and the evenings were mild. They 

 received grass only after being turned out. Notwithstanding 

 this complete change of conditions there were practically no 

 changes in the quantity or quality of the milk. From March 

 4th till 10th each cow received daily 86 Ib mangels, 20 Ib hay, 

 and 10 Ib linseed cake. On March llth a compound cake 

 replaced the linseed cake, with no change in the quantity or 

 quality of the milk. On March 24th, 6 Ib of another compound 

 cake with 4 Ib of maize and oatmeal were given, and still 

 there was no change in the milk. The quantity of mangels 

 given was reduced to 50 Ib per cow daily on April 23rd, but the 

 quantity and quality of the milk produced by the cows were 

 not reduced thereby. Nor was this so when the mangels 

 were withdrawn altogether on April 30th. When the mangels 

 were stopped the cows would have remained out all day if the 

 weather had been fair, but as wet weather followed, they were 

 out only for the same time as before. 



Individual milk. The individual milk, as well as the 

 mixed milk, of 6 to 8 cows was tested once every fortnight from 

 March 5th till June 18th, 1903. The solids not fat were in 

 eighteen instances under the 8'5 per cent, standard out of 

 128 tests of the milk of the individual cows. They were 

 always above the standard in March and April. The cases 

 when they were under standard occurred in May, June, and 

 July. At no time did the fat or solids not fat fall below the
