raaize-meal respectively is still continued, but much smaller amounts 
are used and only once in the rotation, viz. when the roots are being 
fed off. This plan has been continued from 1885 up to the present. 
The table on page 366 represents the cropping. 
Seeds. — Red clover was sown among the barley early in May at 
the rate of 16 lb. per acre. The following year it was cut, for the 
first time in June, and the second time in the middle of August. 
The weights obtained in 1889 and 1890 are given in Table III.

Although in the barley crop of 1888 preceding the clover of 1889, 
the manured half (plots 1, 2, 3, 4,) had shown much higher returns 
than the unmanured half, whilst there was indication of this also 
with the barley of 1889, the differences are not observable in the 
above clover crops. 
WJieaf. — After ploughing up the previous clover-root, 8 pecks 
per acre of Browick wheat were drilled late in October or early in 
November in each year, and the crop was cut and harvested August 
15-28 the following year. The results are given in Table IV., 
page 368. 
In both years, and more especially in 1889, there is evidence of 
the somewhat higher fertility of the plots comprising the manured 
half of the rotation. Also in 1890 the superiority of the cotton- 
cake to the maize-meal plots is indicated througliout. It might be 
mentioned here that iii 1885 when wheat was last grown on Rota-
