538 Miscellaneous Implements Exhibited at Doncaster. 
ments of which are controlled entirely by the leading wheel. 
The finger-bar cannot be floated over a hollow, for it is quite 
independent of the movements of the pole ; neither can it drop 
perpendicularly into it, as the leading wheel by which it is en- 
tirely controlled will raise or depress the finger-points as occa- 
sion may require, and so cause the fingers to follow the forma- 
tion of the ground over which the}* are passing. The finger- 
bar of an ordinary mower is held rigidly in one position by the 
tipping lever, and, in coming to a hollow place, will be either 
floated over it altogether or will drop perpendicularly into it. 
The same makers have introduced an improvement (Arts. 
2902-5) in the construction of turnip-cutter knives, which is 
worthy of notice. The knives — Tipton's patent — are made with 
an acute angle, so that when the barrel revolves they strike the 
roots with a point instead of with a broad edge, thus pinning 
the roots, and preventing them from jumping about in the 
hopper, thereby rendering the work more easy and more expe- 
ditious. 
Mr. Robert Maynanl, Whittlesford Works, near Cambridge, 
showed a useful novelty in his Chaff" Presser and Bagger, which 
is worked in connection with the chaff-cutter (Art. 4309). 
After the chaff is sifted it is taken up an elevator (fig. 14) and 
poured down two cylinders into the sacks. The elevator 
is made suflficiently high to carry the chaff" to the top of the 
tubes, in each of which is a screw. The bags are slipped on 
to the bottoms of the tubes, and the chaff" as it falls into 
the tubes is passed through the screws into the bags. As 
there is resistance given by weights and breaks to a frame 
which presses on the bottoms of the bags, the chaff" is screwed 
into the bags, which sink with the frame as the chaff" presses 
them down. When working, one bag is being filled whilst the 
other is being taken off", and another empty bag hung in its place. 
As soon as the one bag is filled, the chaff" is turned into the other 
by means of a flap which is worked by a lever handle. 4-S the 
chaff" is compressed into half the space it would ordinarily 
occupy, the advantage is easily seen; for it becomes more 
portable, and the cost of transit is reduced, whether by rail for 
great distances, or in carts from one portion of a large farm to 
another. The merits of the hay and straw pressers are thoroughly 
realised, and those who have large quantities of chaff" to move 
will doubtless avail themselves of a contrivance which stands in 
the same relation to chaff" as the former do to hay and straw. 
Mr. Walter A. Wood, o6 Worship Street, E.C, exhibited a 
Single-apron Binder wherein mnny cumbersome and unnecessary 
parts usually found in machines of older make have been dia-
