the bearing parts are so made as to be readily renewable. The 
shaft is of steel, and all the bearings are carefully protected 
against dust. There were two mills shown at Kilburn, the 
smaller one priced at 50/., the other 160Z. I should imagine 
such a mill would be valuable and economical for grinding 
coprolite, phosphates, 6cc. 
Messrs. Entioisle and Kenyon, of Accrington, received second- 
class mention for Riley's patent engineer's vice, remarkable for 
strength and simplicity. It comprises a sliding vice with 
parallel jaws, which can be adjusted so as to receive nearly any 
article by merely pushing the outer jaw in direct with the hand, 
and then tightening the grip by turning the handles through a 
half circle. A vice spindle ending in a cam carries, above, a 
loose serrated grip-piece, which, on the handle being turned, 
locks into a corresponding saw (serrated piece) on the inside 
and above it. Directly it thus engages, the screw thread draws 
the outer jaw in, and fixes the object with a grip which is 
certain. Any size of work can be dealt with, and there is 
nothing to get out of order. Four different entries were made, 
viz., jNo. 1 J. Riley's patent joiner's bench-vice, price 16s. 
This can be changed instantly from -jL- inch to 1 foot, and vice 
vei'sa, by half a turn of the handle. The other entries were : — 
Xo. 1 E. Patent Engineer's Vice, 45-incli jaws. Price 21. 10s. 
Xo. 2 E. ditto 6-inch jaws. Price 57. 
Xo. 1 s. ditto 42-incli jaws, on double stand, with 
wheels. Price 51. 
3fessrs. Everett, Adams, and Co. exhibited a complete novelty 
in their " Simplex " turnip-thinner, which very deservedly re- 
ceived second-class mention. It is a matter of regret that 
circumstances precluded a trial, as the apparent merits of the 
machine would probably have earned for it a silver medal. In 
these days of labour-difficulties, any mechanism that facilitates 
operations which have hitherto required skilled labour, are of 
great value. The Simplex imitates more closely the action of 
the hand-hoe, than any invention I have seen. The drawings 
(Figs. 30, 31) represent the front and side elevations. 
It will be seen that an iron frame is supported by travelling wheels, the 
tires of which have a central rim and cross spuds, to prevent slipping. The 
axle carries a large bevel wheel, which engages a pinion on one end of a shaft, 
which terminates with a disc fitted with a crank-axle, to which are attached 
the coupling-rods carrying the hoes ; to the end of these rods are jointed 
upright rods which are socketed to the frame, and can be raised or lowered 
by a lever handle with segments, seen in Fig. [30. It will be seen that 
bj' this arrangement each hoe can be raised or lowered when the machine 
is in motion, as each hoe works independently of the other. Owing 
to the attachment to the disc, the face of each hoe as it recedes from its 
cut is pitched downwards, so as to discharge any adhering soil. The dis- 
tance between the plants depends upon the size of the hoes and of the
