v/ill with greater ease than by handles. The anti-friction 
principle is most fully carried out, giving lightness both in 
draught and weight, with increased power and efficiency 
in work. 
The depth of the furrows can be regulated from 3 inches to 
8 inches, and the width from 7 inches to 13 inches. It may be 
fitted either with general purpose or with digging breasts and 
shares, and a pair of handles for setting out ridges can also be 
had if desired. 
Messrs. R. A. Lister and Co., No. 827, Corn-Grinding Mill. 
— This mill is adapted for grinding meal for stock, but also for 
preparing flour for domestic purposes. The grinding part is 
this firm's ordinary "Vertical stone mill," carried by two brackets 
which are bolted on to the dressing part. The corn passes first 
from the hopper into the shaking-shoe, in which is fixed a wire 
screen to collect any stones, sticks, nails, &c., before it passes 
into the mill. The stones being vertical, the corn passes from 
the shaking-shoe into an opening on to a worm, which is keyed 
on the shaft which carries the runner stone. Being thus de- 
posited on the face of the stone, it is ground and passes into the 
separator, producing three different degrees of fineness of flour 
and bran. The dressing apparatus consists of a circular barrel 
covered with graduated brass-woven wirework, in the centre of 
which revolves a brush with three arms, driven by a strap on the 
mill-spindle. In case of no need of any separation, a tipping- 
plane is provided that will turn the meal into a sack or bin with- 
out passing through the dresser. The cost of this mill is 25/., and 
it is capable of grinding and dressing from 6 to 8 bushels of fine 
meal per hour, and requires only a 3 or 4 horse-power gear, 
worked by steam or water power. The stones are easily taken 
apart for dressing. Messrs. Lister have recently taken out a 
patent for bolting the fixed stone to the iron casing, also for 
putting the runner stone in a pan with angular and spiral ribs 
cast on the outside, causing the stone to be perfectly balanced, 
and at the same time producing a current of air, essential for 
cooling the meal and keeping the cases perfectly clear. No. 828, 
exhibited also on this stand, is a small mill on the same 
principle, worked by hand for domestic purposes. 
The Albion Ironioorhs Co., No. 2491, Pulper or Shredder 
and Slicer. — The chief novelty of this machine, made on the 
disc principle, is the adaptation of a single disc wheel to the 
separate and distinct operations of pulping or shredding, and of 
slicing all kinds of roots, and by the addition of grass-cutting 
plates it also makes a very efficient fingerer, thus constituting a 
simple treble-action machine. In all other machines of this 
class two or more discs are required, and this adds to the cost. 
The knives, patented, are of a special shape, four for pulping or
