Bones and Sulphuric Acid as Manures.

and enterprise has brought out the exertions of our enguieers and 
mechanics, who have, in a short space of time, effected many great 
improvements and removed many obstacles which we liad accus- 
tomed ourselves from long habitude to consider as immovable. 
In this case, therefore, I have no doubt but that the engineer will 
come to our aid, and put us in possession of a simple agent by 
which so valuable an application may be made use of without in- 
convenience. Indeed I have good grounds for this hope. Within 
the last few weeks I have drawn the attention of Mr. Crosskill, of 
Beverley, to the subject, and he informs me of his readiness to give 
it his best consideration, and hopes to be able to make such addi- 
tions to his liquid manin-e cart as will enable it to deposit the solu- 
tion in the ridges, and to act as an eflicient drill for the purpose. 
7'here was a very clever drill for liquid manure and seed, made by 
Mr. Huckvale, shown at the Royal Meeting at Derby last year, 
which I have no doubt would answer our purpose. Tiie main ob- 
jection to such an implement is on the score of economy. It can- 
not beexj^ected that the farmer should procure a fresh drill, espe- 
cially one for depositing seed and tillage at one time, for every 
variety of fertilizer which he may use. Any arrangement which 
may be made to act with the common water-cart, or with.a manure- 
cart so much used as Mr. Crosskill's, is likely to be a great ac- 
quisition to the public, as the seed does not require to be drilled at 
the same time as the liquid, but can be more conveniently applied 
with the ordinary small drill upon the ridges, after the manure has 
been covered up. 
A light and economical liquid drill-cart may be made of a com- 
mon barrel that will hold about 36 gallons. This should be fixed 
to shafts, and have a tube through which the liquid may run into 
the ridge. The speed of the horse will regulate the quantity of 
liquid applied. It may, however, also be well to have two or 
three nozzles of various diameters, which will screw upon the 
end of the tube, and regulate the flow of liquid. The barrel 
should be placed below the axle, as it would allow a stirrer to be 
easily inserted so as to keep the liquid in agitation, by which means 
a sediment would not fall to the bottom, and the even distribution 
of the mixture would be facilitated. With such an implement it 
willonlv be necessary to ridge the land, as for iarm-manure ; brush 
oft' the tops of the ridges so that a little loose soil may fall into the 
furrow; put such quantity of the strong mixture from the cask as 
will serve for one or two rows, at the rate per acre we have deter- 
mined upon, into the drill-cart; add the proper quantity of water 
for dilution to it when put into the drill (say 8 or 10 gallons of 
water to 1 of mixture, or otherwise, as we may calculate the proper 
proportion to be), and to pass along the line of ridges dropping 
the liquid upon the loose soil in the furrow. After this the ridges
