200 lbs. (about 4 bushels) of bone-dust, 
dissolved in 100 lbs. of sidjihuric acid, 
and 300 lbs. of water. After this mix- 
ture had lain a few days, and bt-eu 
stirred daily, it was further diluted with 
water, mixed with mould, and laid into 
the drills dry. Poor sandy soil.

The same quantity of bonesaiid sulphuric

The best crop of the yellow 
turnips. As a proof, I sold 
my turnips, to be eaten by 
cattle in my byres, and in 
December I wished to get 
biick two acres at the price I 
sold them at. No. 5 were 
eaten. I was refused the tur- 
nips off No. t), but got two 
acres off No. 4. 
No. 7.

Sulphuric acid and bone liquid, same as 
Nos. 3 and C. Soil poor and various; 
most of it lately in a crofter's, or sub- 
tenant's hands, had two and three white 
crops following.

Plants much later in starting. 
Crop much the same as No. 7, 
certainly not better. 
I do not tliink it likely that a constant repetition on the same 
ground of the sulphuric acid and bone-liquid would answer; but 
there is no deception in this statement of its effects, and there 
appear to be other advantages than the small cost of the liquid, 
viz., the quick starting and growth of the plants, which have here 
on all occasions come to the hoe nine or ten days sooner than from 
other manures ; and with proper implements the liquid can be 
put into the ground at less expense than most other manures. 
In a circle in the centre of No. 1, there was nearly an acre of 
the plants extremely small and weak; about the middle of July 
I neutralized about 160 gallons of cattle-urine with sulphuric
