Field Experiments on Clover- Seeds 
employment of it as a top-drossing for grass or corn-crops which 
are intended to be grown on naturally poor sandy soils. 
Clover Experiments made in 1867, at Txthney Warren, Abintjdon. 
In the next place, I have to record another series of experi- 
ments, which were tried in 1867 at Tubney Warren Farm, 
Abingdon, l)y my friend and former pupil, jNIr. James Kimber. 
In these experiments the same artificial manures were used as 
those employed in the preceding series. 
In Mr. Kimber's experiments, a mixture of different kinds of 
clover-seeds was sown without rye or other grass-seeds on all the 
barley-crop in the preceding year, after a good one of swedes, 
manured with dung, and o cwts. of superphosphate per acre, and, 
fed off by sheep eating corn. 
The manures were applied early in March. 
The effect of some of the dressings became very soon apparent 
in the yellow sickly appearance of several of the plots. The soil 
of the experimental field was in a good agricultural condition, 
but naturally it is very light and poor, and deficient in alkalies 
and lime. It contains nearly 90 per cent, of fine quartz-sand. 
The field on which the clovers were grown formed part of an old 
heath. It has been in cultivation eleven years, and had grown 
clover once before. 
The second crop of clover on such light sandy land seldom 
comes to much. For this reason, the first crop was allowed to 
stand late, and get well matured, before it was cut. The crop 
was harvested in the middle of July, and Aveighed on the same 
day that it was cut. The following Table shows the result ot 
the several experimental plots : —
