degree of tenacity to the soil, and kills the slugs and worms. 2. He 
presses the soil for wheat. 3. Always eats ofl' the turnips with sheep. 
4. He now presses the land for bailey in the same manner as for wheat ; 
and I advised him to make doubly certain by rolling the clover imme- 
diately after harvest, which the farmers of Canipsal are doing with very 
beneficial eflect. 
Again, there is through the greatest part of Yorkshire a strong geo- 
logical jiroofof the truth of the theory. From Tadcastcr to the borders of 
Nottinghamshire, the magnesian limestone formation consists of two beds 
of rock, with a bed of red marl interposed between them : the latter forms 
a strong land, and when drained artificially or naturally by a steep in- 
clination, produces excellent seeds and red clover. Now, wherever the 
red marl and upper rock form one hill-side, and a single field of clover 
extends over both, or contiguous fields are producing this crop at this 
time of the year, the boundary of the strata is marked out with the 
greatest precision, either by the inferior quality or total absence of the 
clovers upon the rocks, which form comparatively light or p\ilverulent 
soils. 
I beg leave to add that I feel the more obliged by the Duke of Port- 
land's correction, because there are few men who, without the slightest 
ostentation, have so much advanced the best interests of agriculture.

XIV. — Experiments on Manures. By Francis Clowes. 
To James Ilvclson, Esq. 
Dear Sir, — Some time since I promised I would send you the result of 
some experiments I was then trying, and I now take the liberty of so 
doing, and adding thereto some of more recent date. In the early part 
of June, 1841, 1 was induced to try saltpetre and nitrate of soda at 1 cwt. 
per acre, and salt and lime at the rate of 30 bush., but unfortunately 
during harvest the several plots became so intermi,\ed, I could not 
arrive at any satisfactory conclusion, but so far as the eye may be relied 
on — which by the way is very, very little — I may perhajjs be allowed to 
say that in the barley on which it was tried I could not see any superiority, 
while in the wheat, where it was also tried, I could at harvest plainly see 
a superiority of as much as 6 inches in the length of the straw, and a 
finer ear ; and I think the finest ear and longest straw were where the 
salt and lime were applied, which also killed all grass and weeds grow- 
ing among the wheat, while the other two evidently nursed it up ; but as 
I cannot say anything about the weights and measures of each, my ex- 
periments are of little use, although I am thankful to say my land is of 
that quality, my barley may easily be spoiled by sheep-feeding turnips, 
and my wheat the same by too high farming. I will now turn to some 
few experiments on grass and turnips, and here weight and measure 
must speak for themselves j and it may not be out of place to observe,
