Bones and Sulphuric Acid as Manures. 
451 
This Report was abridged from the state I gave in. 
Nos. 10 and 14. — The bones were watered witii the sulphuric acid 
the (hiy preceding being sown. 
No. 8. — The sulphate of ammonia, guano, and bones, were mixed 
together. 
No. 11. — The sulphate of ammonia used was dissolved with the 
liquid. 
No. 13. — The ammonia was sown on the turnips on the 22nd Sep- 
tember ; the weather being dry, it affected the leaves for a time, but 
afterwards the leaves became more vigorous ; but the bulb did not grow 
in proportion. 
Nos. 16 and 17. — The bones and guano were dibbled in with a mix- 
ture of saw-dust. 
Part of two drills of each experiment, measuring 4 perches, were 
topped, tailed, and carefully weighed on 13th and 14th December. 
The quantity experimented on was 30 acres, 2 roods, 29 falls. The 
liquid manure was prepared in the same way as reported on last year; 
but in place of being applied with a watering-pan, as then, it was put on 
with a cart, constructed on purpose, to do three drills at a time, and so 
as to give a regular and uniform discharge when nearly empty as when 
full, which cannot be done by any common discharge pipe. When the 
proportion of 2 bushels of bone-dust per Scots acre, or 1 3-5th imperial 
with the sulphuric acid, were applied with the full proportion of water, 
nearly according to Liebig, a portion of the mi.xture, equal to half a 
bushel of bones, was put into the cart, and filled with water, which went 
over exactly one-quarter of a Scots acre, the horse going at the rate of 
three miles an hour. When 4 bushels were applied with the acid to 
the Scots acre, with the same proportion of water in like manner, a half 
bushel was put in and filled up, which went over the quarter of an acre 
as before; but this had to be repeated, and gone over a second time. 
In order, if possible, to save this labour, several experiments were tried,' 
with half the quantity of water; in this case the full bushel of mixture 
of bones and acid was put in at once, and the cart filled up with water, 
and went over the quarter of an acre Scots, thus effecting a considerable 
saving of labour ; and, as far as I can judge from the experiments, with 
equal effect. When the proper proportion of water to be put in the 
mixture is ascertained by experience, the plugs which regulate the dis- 
charge may be graduated, and a series of them made so as to regulate 
the quantity of mixture per acre during pleasure, the horse going at the 
regular and common pace, without having to do so by augmenting or 
lessening the quantity of water, or by making the horse go faster or 
slower, the latter being difficult to regulate. 
Crop 1844. 
With regard to crop 1844, the Swedes were raised with manure 
and liquid, as last year, but less farm-yard manure applied per 
acre : j^ood crop. 
Having been disappointed of a full supply of bone-dust early
