Tank-clmnscrs. — A silver mcd.il was given to Messrs. De.an, 
Dray, and Dean, for their tank-cleanser, which was thoroujjhly 
tested by the Judo^es, and found to perform in a very satisfactory 
manner. The body of this is simply a liquid-manure cart, and 
its merit consists in the convenient mode of fillin<j it, which is 
done by an exhauslintj pump fixed on the top of the machine, 
and a flexible hose of large capacity fixed also on the top of the 
vessel : the hose can be lenjfthened to any required extent. 
These contrivances on trial were proved to be capable of convey- 
in": into the vessel any matter (or even substance that was not too 
large for the hose) that is at all in a fluid state. This machine 
mav be of consideral)le utility in cleansing tanks or cesspools that 
are not easily accessible, or where the contents are of more than 
ordinary consistency, 
A Cheese-press exhibited by Mr. Bruckshaw, of Longslow, near 
Market Drayton, was considered to possess merit sufficient to 
entitle it to a medal. It is mounted on a cast-iron bench, and is 
calculated to give a varied and almost unlimited pressure by 
merely moving a pin, or roller, into different recesses, which pin 
acts as the fulcrum to the lever which gives the pressure. 
A medal was awarded to Mr. Summers, of Wold Newton, near 
Bridlington, for his implement for removing shocks of corn. This 
was perhaps the simplest if not the lowest-priced article in the 
exhibition. It consists of two longitudinal bars like the handles 
of a sedan-chair, connected by two slots or cross-bars. Tliese 
slots are fixed in one of the longitudinal bars, and made to slide 
easily through the other, thus allowing the side bars to expand. 
These side-bars have iron spikes 6 or 8 inches long on their inner 
sides, so that, by this simple contrivance, two workmen are enabled 
to grasp a whole shock of corn, and remove it without disturbing 
its arrangement. As in most seasons shocks of corn standing on 
young seeds require to be removed once at least belbre being 
finally carried, in order to prevent injury to the clover, this imple- 
ment, simple as it is, may be of considerable use. 
Mr. Blundell, of Theberton-street, Islington, London, exhibited 
an agricultural drainage level, on a new principle, for which the 
judges awarded a medal. It is simply an angular frame-work of 
wood, suspended on bearings on a vertical plane, resting on three 
feet in the usual manner. The sights are on the upper edge of 
the angular frame, and it is furnished with the necessary screws 
for shifting the line of view, and fixing it when in the right posi- 
tion. The spirit is contained in an endless tube, bent in the 
shape of an isosceles triangle ; the side or base of which is vertical, 
and exposed to view. In this vertical side of the tube the spirit 
rises and falls, close to the edge of an index, and indicates thereon 
the angle made by the line of sight with the line of true level.
