G3Q Miscellaneous Implements Exhibited at Plymouth. 
on soft land and bad roads, otherwise carnages of this weight 
would surely not be offered to farmers. 
Mr. T. II. Brigg, Bradford, exhibited an Automatic Easy 
Draught Attachment for Carts (Art. 13G3). This was shown at j 
Windsor, and the only claim to novelty this year is the adjust- 1 
ment of the traction levers in such a manner that their action 
multiplies in proportion to the resistance of the load. From a. few 
practical tests which the Judges applied to the invention, there 
did not appear to be any extraordinary diminution of effort in con- 
sequence of its use. The tests were of course rough and ready 
ones, and did not pretend to be scientific or exhaustive ; but I 
think we were justified in supposing that so great an advantage 
to the horse as is claimed in this attachment should be evident 
to the eye without the assistance of a dynamometer. 
The end that Mr. Brigg has in view, viz. controlling the 
angle of draught to suit the constantly varying conditions of 
the horse's work, is a most important one to farmers, and too 
often lost sight of, or we should not so frequently see horses 
flogged to get a heavy load up a hill, when a sack or two trans- 
ferred from the waggon to the horses' backs would enable them 
to pull it with the greatest ease. Neither should we so often see 
horses yoked at length instead of abreast — a lamentable loss of 
power. I hope Mr. Brigg will persevere until he gives us a 
strong, simple attachment, suitable for agricultui'al carriages, 
and such as may effect a great saving of horse-flesh. 
Messrs. Wm. Brenton & Co., Polbathic, St. Germans. — Corn- 
sower, broadcast (Art. 138G). In this implement the seed-de- 
liverer consists of a roller having a concave surface (like a pulley 
wheel), with a number of curved teeth round its smallest diameter 
adapted to move the grain towards the discharge opening. 
Mr. B. II. Williams, Liskeard — a Turn-wrest Digging 
Plough (Art. 1433). In giving this plough a field trial, the 
Judges do not wish it to be thought that they themselves are 
in favour of turn-wrest ploughs for general purposes. They 
think the verdict of the country is against their use ; but their 
reason for the trial was that they understood that these ploughs 
are very commonly used in the Plymouth district. They there- 
fore thought it their duty to test Mr. Williams's plough, as the 
principle on which it works is, they think, new, and has a good 
deal to recommend it. The general construction, however, 
scarcely does justice to the principle. 
The breast and sock swing together on an upright pivot fixed to the 
centre of the beam, right or left as required, by means of worm and spur 
gearing, with a long iron connecting rod, and crank handle within reach of 
the ploughman. The coulter is reversed with a simple crank, worked by a 
light rod, also convenient to the ploughman,
