III. Hay from Imperata arundinacea ( Chigaya). 
Imperata arundinacea is a liarsh tall grass, which 
makes up the bulk of végétation on the slopes of uncultivated 
hills and mountains, as well as on the waste land of the 
plains. A specimen of hay made from this plant was 
examined in the winter of 1882 by Mr. T. Yoshii. Two 
rams, No. I a Merino, No. II a Southdown, received per 
day and head 1 Kilogram, but did not consume this ration 
completely. Sheep No. I left very considerable quantities, 
'(nearly 350 Grams), every day, while the other animal 
consumed little more than 900 Grams. The x’esidues were 
collected every day and separately analyzed. 
The quantity of hay left uneaten, the amount of water 
drunk, the proportion of fæces and the variations of the 
live-weights are shown by the following table :—
