The hopper is very deep, and the angle such that there is no fear of choking. 
The great diflcrcnce between this and the machine first described was in the 
quality of the pulp, and this, wo tliought, arose from two circumstances, — 
the long, narrow clearance openings, and the possibility of a narrow slice pass- 
ing between the disc and the hopper or fiice-plate. It was also noticeable that 
more jiulp came out of the top, and there was more juice expressed, conse- 
quently more pressure. Price, without pulley Gl. 5s. 
Of the machines with knives on a revolving barrel, the Judges, though 
disapproving of the principle, considered the entries of T. Corbett, and Corbett 
and Son, which are identical save in trifling details, deserving of commenda- 
tion on account of the quantity and quality of the work. The casing of the 
barrel is in 6 sections ; tlie teeth, which are diamond-pointed, are drilled, and 
cast with the sections. There are 5 rows of teeth in each section, and 9 teeth 
in each row. The teeth, or knives, are self-sharpening, being thickest at the 
base. Half-circular openings in front of the teeth, f inch, admit the pul]i, when 
made, into the barrel. A weight suspended from the axle tends to remove 
the ])ulp ; but as there is some space between the bottom of this weight and 
the inside of the barrel the pulp gets pressed into a compact mass, which 
would soon decompose and smell. Moreover, this pendulum cleaner must, to 
a certain extent, bruise the pulp and thereby cause an extraction of juice. 
The sections can be rejilaced at 2s. each — rather a serious expense in the event 
of frequent breakage. The price, with pulleys, 61. 10s. The work was much 
better than we anticipated. 
i?. Mellard, of the Trent Foundry, exhibited a treble-action disc root- 
pulper, stripper, and slicer, the different actions being secured by a double disc 
and a moveable door. The form of the hopper was not good, and consequently 
the roots clogged several times ; the bearings were roughly made, the quality 
of the pulp fair. 
E. 11. i?e?;taZZ showed both disc and barrel pulper, the latter furnished with a 
worm cleaner worked by cog-gearing. This machine threw the pulp about 
very much, and the roots were rolled round and round in the process of 
cutting, consequently the juice was expressed. The disc-cutter was roughly 
made, the disc-shaft not true ; and this, and too much opening between the 
disc and the face-plate, accounted for the proportion of large strips which came 
out with good pulp. 
For Steaming Apparatus for the Preparation of Food for Stock, £20. 
In those districts where the potato is grown largely as a field crop, an econo- 
mical steaming apparatus becomes almost a necessity, for the value of the 
small chats when steamed, over the same in a raw state, is very considerable, 
and sufficient to render the investment a good one. Messrs. Amies and Barford, 
of Peterborough, have been long favourably known in connection with these 
apparatus, and on the present occasion their only competitor was a friendlj- 
one — viz., Mr. Valentine Barford, a brotlier of one of the firm. 
No. 232. Price, 2GI. lOs. — Consists of a wrought-iron vertical steam- 
generator, holding 30 gallons of water, fixed in the centre, on one side a 
galvauised-iron vessel, so placed on an axis as to swing, and thus readily 
disgorge its contents when reversed. This vessel is capable of holding 9 
bushels of potatoes or other vegetables. The steam is conveyed by a 1-inch 
pipe. On the other side of the generator is a strong double-cased galvanised-
