English model with certain modifications. First, I have to notice a power 
machine with Crowley's arrangement of gearing, and Richmond and Chandler's 
knives; this cuts six different lengths, from J to 2 inches; by clutch-gearing 
on the first and second motion shafts, three changes are effected ; the rest by 
changing the pinions. The gearing is carefully boxed off. Month-piece of 
steel. The same firm exhibit Toulton's combined Pea-cleaner and Pneumatic 
Chaff-carrier, an ingenious combination by which the peas are separated from 
the pods without being so much broken as by the drum of a threshing- 
machine. The haulm is cut into chaff; the latter is separated from the peas 
and blown up the carrier to a considerable distance, whilst the peas are collected 
below. The retail price of the apparatus is 18/. In the Pneumatic Chaff- 
cutter, also shown by Mr. Watson, the fly-wheel, in addition to the knives, 
has four wooden blades standing out at right-angles, which generate sufficient 
wind to blow the chaff through a tube for a considerable distance. The air 
enters under the box. The defect in this machine is that the handle of the 
dutch, by which the machine is stopped, is on the right-hand side of the box 
at the extreme end of the pinion shaft, and quite beyond the reach of the 
feeder in case of accident. There is no protection of any kind, and unless 
the Canadians are much more careful than Englishmen, serious accidents 
must occur. In no machine did I find the revolving wooden roller in front 
of the feed-rollers, which we think should never be absent. 
David Maxwell, of Paris, Ontario, is the inventor of a power Chaff-cutter 
with patent gearing, by which the rollers can be stopped, reversed, and 
size of cut changed without the use of a clutch or change of wheels. Thus 
Mr. Maxwell secures the ability to stop, reverse, and change cut, without 
clutch-gear or change of pinions. A further alteration of the size of cut can 
be effected by reversing a pinion on the second-motion shaft. The face of the 
jaw is chilled cast iron ; the feed-rollers are not affected by opening of jaws, 
as the upper shaft has play. This is a powerful and well-made machine, with 
fairly good provisions for safety. 
Mr. A. Anderson, of London, Ontario, exhibited an admirable hand-cutter, 
without wheel or gearing. The blade is attached to a wooden handle, the 
other end terminating in a pin, which travels up and down in a slot. It is of 
diagonal form, with ragged edges. The length of cut is regulated by a feed- 
board attached to the above-mentioned pin at the lower end, and having the 
necessary play by means of a slot and bolt attached to the frame. An india- 
rubber tension-spring steadies the cut. For simplicity, efficiency, and reason- 
able cost, this invention is worthy of high praise. Several thousands were 
sold during the Exhibition ; the retail price was nine dollars, Canadian money. 
The same exhibitor showed a clever bread-knife and hay-cutter, with similarly 
constructed blades. 
The only exhibits of Slicers and Pulpers for preparing roots 
for animal food were shown by Mr. John Watson. His Triple- 
action Pulper, Ribbon Cutter, and Slicer, is a valuable combina- 
tion, comprising two discs revolving on the same shaft, one fur- 
nished with pulping-blades, the other with slicing and ribbon 
knives. The hopper is in two parts, with a hinged plate to 
cover over either portion as desired. The pulping-knives can 
be brought forward or backward so as to regulate the size of the 
pulp. The Gardner's Cutter and Slicer is an improvement on 
the well-known English machine. It has a sliding division- 
plate or hopper, which insures the roots being continuously 
presented to the cutting surface.
