ACTION OF LIME AS A MANURE.

It acquires an inferior taste and lustre and becomes lighter, the 
hulls grow thicker, the white spots in the grain become larger, 
and sensible losses are experienced during the hulling and 
cleaning, because the grains being brittle break dpring these 
operations. 
My attention was called to the latter point on the occasion 
of the third national exhibition in Tokyo, and as similar 
observations have not yet been made with any of the other 
cereals, and were therefore of considerable interest, I procured 
through Mr. S. Kikkawa 5 specimens of hulled rice from the 
province of Iyo in Shikoku, which proved to be exceedingly 
brittle. The chemical examination of these grains was 
made under my control by Mr. S. Shinjo, a graduate of the 
college. Regarding their origin and the manures applied 
the five specimens were accompanied by the following

Specimen No. 1 (Takaratoku) was subjected to a complete 
analysis, the results of which accompanied by those of several 
other analyses of ordinary hulled rice grown without lime near 
Tokyo, were the following:
