wheels revolve a definite number of times in a jjiven distance, at 
whatever pace the horse may be travelling. The silver medal 
was adjudged to Mr. ITuckvale for his perseverance and ingenuity 
in adapting this novel idea to practical uses. 
A seed hand-barrow was exhibited by Mr. James Smyth, jun., 
of Peasenhall, for the more accurate sowing of small seeds by 
machinery than can be done by hand-scattering. The seed-box 
covers a considerable breadth at once ; and precision of delivery is 
secured by cups, instead of brushes, which are the more usual 
but less exact mechanical means used for meting out small seeds 
by the drill. The revolution of the cup-axis is derived by toothed 
gearing from, the barrow-wheel. The arrangement is highly ere 
ditable to Mr. Smyth; and, by reason of its lightness, cheapness, 
and efficiency, this sowing-machine will prove useful to the small 
farmer. 
Drill-Pressers. — Ten machines for forming drills by pressure 
were brought forward by various makers, the greater number of 
them bearing the stamp of improvement, particularly as adapted 
to the deposition of seed and manure. After a careful examina- 
tion, the Society's prize of 10^. was awarded to Mr. John Caborn, 
of Denton, Grantham, for a two-row implement, having wheels 
3 feet 8 inches in diameter, and comprising very effective arrange 
ments for depositing the manure in the trenches. The price ol 
this machine is also moderate. 
Dihhlers. — The collection of the Earl of Ducie contained the 
dibbling and sowing machine with five wheels, invented by James 
Wilmot, rewarded at Liverpool, and described in that Report. 
No improvement was observed on the original specimen, but the 
machine was reported as gradually coming into use. 
Mr. Stratton, of Bristol, exhibited the single-row dibbling 
wheel used by Mr. Miles^ M.P., of Kingsweston, chiefly for 
forming the holes to receive the seed of mangold- wurzel. It is a 
tool of the simplest kind, gives mathematical precision to the 
spaces desired between the plants, and is represented by Mr. 
Miles as leaving the holes quite sufficiently true and clear for the 
purpose. It consists of a light wheel, furnished on the rim with 
dibbling points, set at equal distances from each other, and 
making holes 2 inches in depth. The wheel is comprised in a 
frame, and worked by a man. 
Messrs. Cottam and Hallen, of London, produced a two-row 
dibbler, with wheels 3 feet in diameter, the principle of which is 
precisely similar to that last-mentioned, but rendered adaptable 
to a greater number of purposes. The machine is entirely con- 
structed of light iron. The dibble points are adjustable to any 
distance from each other ; and the wheels can be set at any space 
asunder from 4 to 36 inches. A man can work it on light soils,
