Experiments on Manures. 
the experiments on grasses arc all carried on in square chains, and 
therefore I have necessarily taken the tenth of the usual quantity of 
manure applied to an acre of land for each plot : the turnips are manured 
by the acre and weighed by the square chain. The parish of Henisley, 
in which my farm lies, is on the seacoast, about 6 miles to the north of 
Great Yarmouth ; the fields on which the experiments were tried are all 
Avithin g mile of the sea; the soil is of a mixed freeworking loam, 
varying from 2 to 4 feet in dei)th, with a subsoil of brick earth and field 
clay. The grasses, trefoil or yellow clover, white clover, and the 
common rye-grass, were of the first year's lay. 
On the 7th of April, 1841, the following manures were sown broad- 
cast :— 
s. d. Cwt. qrs. Uis. 
No. 1. lljlbs. of saltpeh-e, cost, cartage, &c., 3 3 produced 5 2 Oof hay. 
2. 11^ lbs. of nitrate of soda, do. 2 8 do. 5 0 0 do. 
3. 1 ton of fish-mould, do. 2 0 do. 4 3 23 do. 
4. 1 ton of frpsh stable-manure, do. 2 0 do. 4 3 19 do. 
5. 6 bush, of salt and lime, do. 5 0 do. 3 3 8 do. 
6. Soil simple, . . . . . . do. 4 0 11 do. 
The grass was mowed and strewed on the morning of the 15th of 
June, and weighed on the 17th in the afternoon, at which time it was in 
a fit state for carting, it having been very fine weather; very shortly 
after the manures were put on, I could plainly see a difference in the 
colour of the grass in Nos. 1, 2, and 3, and when cut. No. 3 was, to all 
appearance, the best, at once pointing out the fallacy of the eye. I have 
valued my hay at 4?. per cwt., and notwithstanding my loss in No. 5, 
and after deducting the expense of the manures, I have a net profit of 
\s. 4c/. on the whole of the above experiment?, and showing a gain of 
2s. 9c/. Bet in No. 1 over No. 6. 
The same year, on the 13th of April, with similar grasses and soil, in 
a field rather nearer the sea than that just described, 1 had the following 
maiuires sown broadcast : as you will see, when compared with the last 
field, I have used half the quantity of salt and lime, and double that of 
saltpetre and nitrate of soda, with the same of fish-mould and stable- 
dung : — 
No. 1. 2J busli. of salt and lime, 
2. 23 lbs. of nitrate of soda, 
3. 23 lbs. of saltpetre, 
4. 1 ton of fish-mould, 
5. 1 ton of stable-dung (fresh) 
C. Soil simple, . . . 
The hay was mowed and strewed on the 16th of June, and weighed 
on the 18th, when in a fit state for carting: it will be seen that nitrate 
of soda here has the best of it, and that, setting my hay at As. per cwt., 
I am a gainer in this field of 1?. 2d. on the whole of the experiments; by 
No. 1, I lose the cost of the manure, and by No. 5, I lose \s. 9d. worth 
of hay, beside the cost of the manure : and thus I account for my loss in 
No. b — the stable-dung being set on late, and being long, did not wash 
into the land enough, consequently the grass was not mowed so low by 
some 2 or 3 inches as on the other squares. 
In 1842 I tried similar experiments on red clover; but after the
