Manures.— It having been ascertained that the soils of the 
wolds, those of the Kelloways rock and inferior oolite, con- 
tain comparatively a very small proportion of alumina and 
lime ; — and if not only firmness and consistency be imparted 
by these earths, but also the power of condensing and 
absorbing carbonic and ammoniacal gases is given to the 
soil, — it is easy to perceive the reason why these lands 
require a frequent application of manure, and particularly 
as they are always porous, so as to admit a free circula- 
tion of the atmosphere, which hastens the decomposition 
of the manures applied to them. Owing to these de- 
ficiencies, this land therefore becomes very expensive in 
the article of manures necessary to be applied in its cul- 
tivation, and the expense of providing manures is increased 
by the general practice of purchasing foreign manures, and 
neglecting the care and preservation of those which could be 
collected at home; and that the expense will increase, is 
probable from the present advanced price of bones and 
rape-dust, to which is to be added, the less effect from the 
same manures being placed unremittingly upon the same 
soils. It becomes then an important inquiry, whether any 
other manure equally valuable may not be procured as a 
substitute and at a less cost.
