INFLUENCE OF MANURES ON GRASS LAND. 163

It will be seen that although the kainit has added only 
17 cwt. of hay to the general yield, it has more than doubled 
the percentage and yield of Leguminose, and has doubtless 
greatly improved the quality of the produce. 
On examining the effects on the Leguminose of increasing 
doses of kainit (Table X.) it will be seen that the largest 
dose has at each station produced the highest percentage of 
these plants, the average for the four stations being—

The increase in the percentage and weight of Leguminose 
is perhaps less than might have been expected, which would 
indicate that a dose of about 2 cwt. of kainit is as much as is 
usually necessary for annual application to old-land hay. 
The influence on Leguminose of Lime.—The experiments 
have furnished no evidence to justify any definite conclusion 
in regard to this matter. 
RIBWORT (TABLES XI. AND XII). 
As each of the eight stations showed a considerable, 
generally a large, amount of ribwort (Plantago lanceolata), it 
would appear desirable to examine the behaviour of manures 
towards this plant, which belongs to neither of the families 
we have already looked at—the Graminee and Leguminose. 
Ribwort is characterised by the possession of a well- 
developed tap-root, so that we should expect that it would 
be fairly independent of supplies of superficial nourishment.
