Preliminary Trials. — These trials lasted for a period of three 

 weeks, and at the end of them the two lots of cows stood as follows : —

Rations. — As will be remembered the summer of 1911 was excep- 

 tionally hot and pastures became very bare. Throughout the experiments 

 both lots of cows received per cow per day a mixture of 2 lbs. of soya 

 bean cake, and 2 lbs. of Bombay cotton cake. After 10th July both 

 lots received tares in addition, and on 24th July they were turned on 

 to a clover fogg. On 2nd September, as tares were finished, the cows 

 received a small amount per day of clover cut green, and after 9th 

 September a very small quantity of turnips on the grass. 



During the period of Experiment U, which lasted from 1st July 

 to nth August, the cows of Lot I. were milked at equal intervals of 

 twelve hours each, viz.: — at 6 a.m. and 6 p.m., while those of Lot II. 

 at unequal intervals of fourteen and ten hours respectively, viz. : — 

 at 6 a.m. and 4 p.m.

Results. — A fortniglit elapsed between the end of the preliminaiy 

 trials and the commencement of the actual experiment. Owing no 

 doubt largely to tlio drought thero was a considerable falling off in th© 

 average daily yield of the two lots.
