is utterly inadequate to suit, all soils. Much also of the success of 
this plough is due to the principles of its construction, as already 
explained in the Report of the Derby Meeting. 
Turn-wrest Plough. — Under this generic name for ploughs 
which lay their furrows in one direction, must be classed a novel 
description of the implement, invented by Mr. H. Lowcock, of 
Marldon, Devon, and manufactured by Messrs. RHUsome. Its 
intent is accomplished without having to turn the plough round at 
the end of a bout, or to change, manually, any of its acting parts. 
It consists, in fact, of two ploughs set back to back lengthways, and 
forming one body, having a double flap or wing, hinged between 
the vertical parts of the two mould-boards, and completing their 
necessary curvature. The stilts cr handles are hinged on the centre 
of the plough, and serve to guide it in both directions by simply 
turning them over when the plough reaches the end of its course. 
The horses, whilst turning, leave the plough at rest, but pull the 
draught-chain to the opposite end of the beam along a rod which 
connects the tv. o extremities ; and, so soon as motion recom- 
mences, the flap or wing turns on its hinge froiu the effect of the 
resistance it encounters from the new furrow slice, and the new 
slice is deposited against the preceding one. Thus, a self-acting 
turn-wrest is produced, and in a very simple and efficient manner. 
The novelty of this arrangement consists, chiefly, in the hinged 
self-acting flap ; but the construction of the sole is also entitled to 
much praise, as, though the plough is double, the usual extent 
only of frictional surface is in action. The plough carries one 
wheel at each end. 
The judges awarded a premium of .5/. for this plough, which 
did its work very satisfactorily, and was considered to be the best 
turn- wrest yet invented. 
Stuhble-paring , or Skim Plough. — Several implements bearing 
this title underwent strict trial. The judges had no hesitation in 
determining to which of them a preference was due, as no one of 
them executed its work effectually, excepting that invented by Mr. 
John Bnice, of Tiddington, near Stratford-on-Avon, for which a 
prenuum of 5/. was adjudged. 
Mr. Bruce appears to have thoroughly studied the require- 
ments of an implement of this kind, and has certainly produced 
one which will be considered a great acquisition by the agricul- 
turist. It was tried on a very short, dry, clover ley, cutting 3 
inches deep and 26 inches in breadth. No portion was left uncut. 
It worked well with a pair of horses, and is capable of getting 
over 4 acres per day cleverly. It is so arranged as to be equally 
suitable to ridge and furrow as to flat land. It is readily thrown 
out of work at the end of a field, turns easily, and is furnished 
with a set of tines following the cutting shares, in order to scarify
