muriate of potash. The clover and rye-grass on ph)t 10 were 
both h)ng, strong, and of excellent quality ; the clover especially 
being distinguished by luxuriant broad leaves and a dark green 
colour. On the whole, plot 10 yielded by far the best crop 
both as regards quality and quantity. 
The undressed plot yielded, in round numbers, 5^ tons of 
green food in the first cutting, and nearly 2 tons in the second. 
Muriate of potash, applied alone at the rate of 4 cwts. per acre, 
produced, in round numbers, 6^ tons of green clover-seeds in the 
first cutting and 3i tons in the second, or both cuttings gave an 
increase of 2h tons of superior quality ; whilst mineral super- 
phosphate and muriate of potash mixed together yielded 9 tons 
in the first and nearly 5 tons in the second cutting, thus pro- 
ducing altogether an increase of 6^ tons, or nearly double the 
amount of green clover-seeds grown on the unmanured plot. 
This large increase, it should be observed, was not produced at 
the expense of quality, for, as noticed already, the crop on plot 
10 was by far the best in quality of all the 10 plots, and up to 
the present day the clover stands well here, whilst on most of the 
other plots it is either less luxuriant or has in a great measure 
disappeared. 
Nitrate of soda alone produced, in round numbers, 8^ tons in 
the first cutting and only 2 tons in the second. 
This result is particularly interesting, inasmuch as it showed 
that whilst this saline manure yielded a considerable increase in 
the first cutting it left the land in a more exhausted condition 
than land which has not been dressed with this special manure, 
for the unmanured plot yielded 2J tons in the second cutting, 
and that dressed with nitrate of soda only 2 tons. 
Nitrate of soda thus appears to force an early growth of 
Italian rye-grass for which it seems more suitable than for clover, 
and is more useful when an early cutting is required, and the 
farmer intends to grow a large bulk of green food for the use of 
cow-keepers, instead of a good quality of grass and clover-seeds 
for hay. 
On sandy soils in a poor condition nitrate of soda produces 
very coarse grass ; the Italian rye-grass in the instance before us 
being little better than good oat-straw. On such soils nitrate of 
soda should not be used alone, for it has an unmistakeable 
tendency to exhaust the land. 
Another interesting result to be found in these experiments 
was that mineral superphosphate applied by itself gave hardly 
any increase in either the first or the second cutting. This is 
all the more remarkable, because, in the same set of experiments 
tried in other parts of the country on soils not so light and sandy 
as that on Lord Wenlock's farm at Escrick, mineral superphos- 
phate produced a marked increase in the clover crop, and because
