IMPERIAL COLLEGE OF 
II. Hay from Uncultivated Land (Hara). 
Researches on two specimens of hay from haras have 
been made by Mr. H. Tamai, one of the most successful 
students of our college, who, to our great regret, succumbed 
this year to a cruel disease. 
No. I of the specimens had been procured from Iwa- 
shiro, No. II from the Imperial farm at Shimösa. Both 
consisted in their majority of Eulalia japonica (Kaya), a 
tall, harsh grass, which generally makes up the bulk of the 
plants on recent volcanic formations in Japan. No. 1 
contained a little more of Papilionaceæ, chiefly Lespedeza 
cyrtobotrya (Hagi), and Composites than No. II which was 
remarkable for its content of Equisetum arvense. The 
composition of the two specimens was as follows :

The two kinds of hay as shown by these figures are of 
a very low quality, so poor, indeed, in nutritious components 
that we may look in vain through the whole list of agricul¬ 
tural literature for specimens of mixed grasses of known 
nutritive qualities, which would equal them. They are 
hardly better than rice straw cut before dead ripeness, the 
composition of which will be found in a later part of this
