At Cawstoii the same dressinj^ gave good results, and except 
by the ordinary farming ('plot 13) was only equalled by rape- 
cake and muriate of potash (plot 4<). The possible influence of 
the potash here is, however, discounted by the lower yield of 
plot 5, though this, like plot 4, had a more healthy appearance 
than the other plots. The ordinary farming with ten loads of 
dung, 3^ cwt. of salt, and | cwt. of nitrate of soda, gave a far 
higher return than the artificials. 
Summarising the results, the need of farmyard manure in 
unpropitious seasons on the thin soils of Norfolk has been 
strongly brought out, though it is also clear that it may be 
most usefully supplemented. Nor would it appear that dung 
can be sufficiently replaced by artificial manures, at least in a 
season like 1888 ; nor by rape-cake, which, especially in Norfolk, 
has had many supporters, but which proved in these experi- 
ments very unsatisfactory, 
Experiments on Barley after 8ivedes drawn off the Land, 
and also after WJteat, at BolwicJc. 
These were in repetition of the experiments carried out at 
Whitlingham and Aylsham in previous years. A main point 
was to determine the value of a mixture in great local favour, 
viz. guano and salt, the salt being believed to strengthen the 
straw. Unfortunately, however, for this belief the salt plots 
were in each experiment decidedly the most beaten down of all 
the number. At the same time, the produce both of corn and 
straw was appreciably increased. This is a result not before 
obtained in these experiments, and whether due to an excep- 
tional season or not is uncertain, but will form the basis of 
further inquiry in the future. The unmanured yield was very 
high, viz. 36^ bushels after swedes, and 41 bushels after wheat, 
the land being evidently too good or in too high condition to 
bring out the influence of the manures.

Experiments at Flitcham on the Use of Potash in different forms. 
Some of these continuations of former experiments have 
failed to throw any further light on the question. Mr. Cooke, 
indeed, says that, owing probably to the extensive use of potash 
manures in previous years, it is a matter of extreme difficulty to 
find now on his farm a spot on which the deficiency of potash 
is sufficiently marked to give the required results. One experi- 
ment, however, where white turnips, swedes, and barley were 
all sown on a small spot exceptionally deficient in potash, led to 
some interesting results, the white turnips flourishing, while th© 
swedes and barley were bqth miserable crops.
