[July 2, 1920. 



The rainfall for the various periods of growth was as follows : — 

 Rainfall during Growing Period. 



• The third growth was not actually harvested. 



Upon the results of this trial it can be said that Sudan grass has proved 

 itself a valuable crop for the district for (a) hay or silage, and (6) grazing. 



During the hot, dry summer months it provided green succulent growth, 

 when even the cultivated native grasses were absolutely dry. The butter-fat 

 tests for the month of April were of higher percentage than usual. Several 

 of the cows were tested a second time to ascertain if the first had been 

 correct. The milking herd, during this period, were depastured on the Sudan 

 grass alone, but there was not sufficient for them to be allowed all they 

 wanted, and they were only permitted to remain until it was considered they 

 had had a sufficient ration. The milk yield therefore suffered in quantity. 



Samples of Sudan grass hay, oaten chaff, wheaten chalf, and wheaten hay 

 were forwarded from the farm to the chemist, Mr. Guthrie, who subsequently 

 reported the results of his analyses to be as follows : —
