from cut lengths upon the wires in hopyards. It obviates the use of 
stages and ladders, and saves the expense of hooks, which some- 
times turn upon the wires. As each string is secured along the 
shaft of the tyer while being placed in position, it cannot be 
blown about in windy weather. The knots are immovably fixed 
to the wires, and cannot slip or permit the strings to be blown 
together. As the operator works from the ground he is better 
able to judge where to tie, and is therefore enabled to preserve 
a uniform distance between the strings. It is also valuable for 
repairs to broken strings, and it renders work easy in corners 
and at awkward angles. One man can use it, and with it fix 
about four strings in a minute. 
Article 2616. Messrs. John Crowley & Co., Sheffield. Chaff 
Cutter. Price 28 1. 16s. — Noticeable features are embodied in this 
New Combination Safety Lever Chaff Cutter. The lever is of the 
duplex type, enabling the machine to be stopped or reversed from 
either side ; and it is so arranged that it cannot be moved in a 
wrong direction. A wooden roller, behind the pressure plate at 
the top, obviates danger to the man in charge by preventing a too 
near approach to the feed rollers. By a complete covering system 
every part of the machine, except the pulleys, is protected, 
whereby risk is minimised. Double-toothed rollers move the 
feed to the knives, and release themselves automatically as soon 
as the material is brought to the mouth. The mouthpiece is 
adjustable, and free from any projection which might impede 
the passage to the mouth. As the teeth of the rollers are placed 
diagonally, instead of in the usual rows, a firmer grip is main- 
tained upon the material. The extent of resistance by the 
pressure plate can be adjusted, without ceasing work, by means 
of a set screw. The machine is excellent, and ought to find 
favour with employers, whose liability for accident is now more 
pronounced than ever. 
Article 2667. Messrs. T. J. Syer & Co., 45 Wilson Street, 
London, E.C. Estate Carpenter’s Plow. Price 11. 5s . — The 
plow (fig. 9) is designed to overcome the old difficulty experi- 
enced in making a motion of the fence parallel with the body of 
the tool. The fence is moved by universal action from one 
central screw on turning the thumb wheel, instead of by inde- 
pendent wedges. The arms are thus equally advanced or set 
back. A locking nut secures the screw at the desired distance. 
It is fitted with a convenient handle.

Square, London, S.W. Spring Hub Wheel. Price 31. per pair. — 
By the arrangement of a set of springs, fitted either with ball 
bearings or slides, and adjusted between the axletree or axlebox,
