Field Experiments on Cabbages at Ruspe)', Horsham. 425 
sheep. The linseed-cake might possibly have given a higher 
result but for the loss of weight in the case of one sheep. 
I would, in conclusion, repeat the caution given last year, 
that, in endeavouring to give an idea of the relative values of 
the foods, both as feeding and manurial materials, there are a 
number of causes which will in individual cases render altera- 
tions necessary. It will be evident too that, owing to fall of 
prices since the experiment began, the manurial values given 
appear somewhat too high at the present time. I have therefore 
stated the circumstances exactly as they existed at the time on 
the farm at which the particular experiment was made. Still, 
although local considerations and fall of prices may modify the 
conclusions, the value of decorticated cotton-cake must remain 
indubitable. 
XIX. — Field Experiments on Cabbages at Rusper, Horsham. 
By Bernard Dyer, B. Sc. (Lond.), F.C.S., F.L.S. 
Being desirous of carrying out, during the season of 1886, some 
field experiments on cabbages, I was fortunate in obtaining the 
willing co-operation of Mr. A. F. Parbury, of Rusper, Horsham, 
Sussex, who has on previous occasions been good enough to 
place his farm resources at my disposal for experiments, some 
of which have been already described in this Journal. The 
cabbage-crop is one the value of which is too apt to be 
underrated, and it has so far received very little experimental 
attention. 
The field selected for the purpose was fairly typical of the 
land of the neighbourhood, being a light-coloured adhesive 
clay. Three acres were chosen, which had in 1882-3 borne 
trifolium, manured with 12 loads of dung per acre, and 
with liquid manure. The crop was a good one, and yielded 
two months' good cutting. In 1883-4 wheat was grown without 
manure. In November 1884, about 35 tons of pond refuse, 
mixed with 5 tons of lime, were spread on the field, spring oats 
being sown in 1885, and top-dressed with 1 cwt. of nitrate of 
soda per acre. The field was ploughed in the autumn of 1885, 
and about 11 tons of dung per acre were spread during the 
winter. After lying for some weeks frost-bound, the dung 
was finally ploughed in during March 1886. The land was 
cross-ploughed, and repeatedly harrowed and rolled, in order to 
get as good a seed-bed as possible — always a tedious and some- 
what unsatisfactory operation on such land as this.
