more fitted for the large creamery than for the farmer or estate

of milk with a minimum of trouble and delay. 
Article 1560. — Messrs. J. L. Larkworthy & Co., Lowesmoor 
Iron Works, Worcester. 44 Circular Revolving Harrow, Lees’ 
Patent, to cover 7 feet.” Price 4/. 10s. — This harrow was of 
circular form, in shape something like a cart wheel laid 
horizontally with tines on the underside of its spokes. The 
power for draught purposes was applied to a centre spindle, and 
fixed on this spindle at right angles to it and to the line of 
draught was an arm carrying a weight. The speed at which 
the harrow turned was regulated by the radial adjustment 
of this weight. On being pulled forward by its centre, the 
harrow naturally tended to turn about the point of greatest 
resistance to the forward motion, which point was determined 
by the position of the arm and weight. Of course the natural 
tendency was to work the ground a little deeper on one side 
than the other. 
Article 1650. — Mr. T. M. Jarmain, Haseley Iron Works, 
Wallingford. “ Swath Turner 4 Fore and Aft.’” The general 
mechanism of this implement was much on the same lines as 
last year, the difference being that it was arranged with one 
drum in front and one drum in rear of the axle. It is claimed 
that this arrangement reduces the draft by 25 per cent., and 
allows the machine to be made narrow enough to pass through 
a seven-foot gateway, at the same time giving unlimited clear- 
ance to the crop. 
Article 1718. — Messrs. Barford Jt Perkins , Queen Street 
Iron Works, Peterborough. 44 New Patent Water Ballast Motor 
Roller.” Price 155/. — This fine powerful roller (Fig. 4) was 
propelled by a petrol engine, with magneto ignition, and had 
a single-chain drive on the off side from the counter shaft, 
which was suitably geared down from the engine crank shaft. 
We considered it a most useful machine on carriage drives and 
cricket grounds. 
Article 2489. — Messrs. John Searby & Co., Ltd., Bridge 
Foundry, Rotherham, Yorks. 44 Patent Combined Plough and 
Potato Planter, for planting and covering in one operation.” 
Price 16/. — The necessary change wheels were provided to 
plant the seed potatoes at any interval from twelve inches 
to eighteen inches, advancing by one inch. The frame was so 
constructed as to be capable of planting any width of row, 
and the machine was double breasted and adjustable for deep 
or shallow covering. At an extra cost of 10s., the machine 
could be fitted with a single-breasted plough instead of ridger, 
enabling the operator to turn the whole ridge over or to plough 
on level ground. A novel point about this planter was the
