In this experiment it was sought to test whether sulphate of 
ammonia, or the equivalent of nitrogen as nitrate of soda, would 
give the better result. The theory that sulphate of ammonia 
loses ammonia by its application to chalky soils gains strength 
from the results, which are much in favour of the nitrate. Still 
the result cannot be regarded as conclusive, as a somewhat 
similar result was this year obtained on the non-chalky soil at 
Whitlingham, 
These experiments on chalk land show most forcibly the 
desirability of instituting experiments on all varieties of soil. 
E. Experiments on Swedes. 
This was the scheme drawn up by the Royal Agricultural 
Society, and it was carried out by the following gentlemen. 
(1.) Mr. Garrett Taylor, at Whitlingham. 
(2.) Mr. Cooke, at Flitcham. 
(3.) Mr. Sapwellj at Aylsham. 
The plan of manuring and results are given in Table V. The 
plots 1-12 are those in the original scheme. The others, 13-18, 
are supplementary ones added by the Norfolk Chamber of 
Agriculture. 
The swede field at Whitlingham is a light loam with a sandy 
subsoil. 
At Flitcham a thin surface of lightish mixed soil on chalk ; and 
at Aylsham a light mixed surface soil of about 12 inches over 
10 feet of bright clean building sand. 
(1) At Whitlingham 15 tons of swedes were grown without
