Report on the Exhibition of Implements 
ping: the horses, and with no j^reater trouble to the holder than 
is required by the common plough. Tlie leadin!^-\vheel is on the 
raster or Bath chair principle, and therefore turns with the 
horses ; the hind-wheels can be set to various depths below the 
frame in order to regulate its parallelism with the surface. 
On first examining this machine in the show-yard, it was 
feared that the hind furrow-wheel might press too heavily and 
flatten the lightened earth; but, on trial, no such effect was per- 
ceptible. In fact, some additional weight was requisite to bring 
that wheel to a bearing ; its principal use is for turning and 
setting in at the land's end. The horses may be yoked in line 
or abreast, as may seem best to the farmer, according to the 
state of his land. 
It will be understood that there is a second frame, in which 
the working tines are fixed. This is also of the right-angled 
triangular shape, and is supported l)y and under the main frame. 
The ape.\ of this frame is jointed to one extremity of the lever, 
having its fulcrum on the lieam ; the after part or base of the 
triangle swings upon a rod or centres above the hind-wheels. 
Thus, by elevating or depressing the lever, the tines fixed in this 
frame are lowered into the soil or raised out of it, the degree of 
depression being determined by a stop and holes in an arched 
guide through which the lever passes. Each tine is separately 
adjustable. A general resemblance of arrangement between this 
implement and that of the brakes or scarifiers will be observed ; 
l)ut, on closer examination, it will be acknowledged that no slight 
originality of design has been grafted by Mr. Carson on a prac- 
tical acquaintance with the requirements of a subsoil-pulverizer. 
Five tines, set at different depths, may be used in the furrow, or 
one only ; and it is capable of being employed as a scarifier with 
ten tines; but the Judges did not see its action in the latter 
capacity. The moderate price of this implement, stated to be 
8/., is also no slight additional recommendation of it to agricul- 
turists. A premium of 10^. was awarded to Mr. Carson for this 
admirable invention. 
An excellent many-tined pulverizer and stirrer for lighter 
operations was exhibited by the Earl of Ducie, deriving its 
origin from Mr. Nugent's instrument, and adapted by Mr. John 
Morton, of Chester Hill, to sub-pulverizing after the common 
plough, and for stirring the soil between the rows of turnips, &c. 
This light and easily-managed implement is furnished with one 
leading-wheel. The frame contains eight mortices ibr narrow 
tines, and is so disposed that the tines may follow the plough in 
a nine-inch furrow, and loosen the subsoil, or be set to compre- 
hend a breadth of 18 inches, and pulverize the general mass of 
upturned soil, or, as aforesaid, work between rows. The Judges
