Report of the Trials of Flouf/hs, Harroivs, S^-c., at Hall. 545 
The turninf; at the hcadlaiKls has to be done entirely by the workman. The 
price, without skims, is 8?. 15s. 
Perkim. No. 132. — Parallel beams, of good construction; but unfortunately 
it was evident, both by tlic work and examination, that the i^arfs were badly 
balanced and that the beams, 2j inches by ^ inch, were much too light to resist 
strain of ordinary work. They are well braced with IJ-iiich bolts. The 
draught is taken from the first stay. The friction-wlieel is on an angle, but is 
not adjustable — a decided omission. The mechanical arrangements are excel- 
lent. Two lifting-wheels near, the centre of the plough form a fulcrum on 
which the plough turns with the greatest ease. These wheels are actuated by 
a leverage from the handles or stilts, kept in place by a spring-catch working 
in a bow. The preceding sketch (Fig. 19) will give some idea of the mechanism.

turned during work the right-hand wheel is so much more forward than is 
here shown, that it is quite clear of the furrow. No slades on either plough. 
The implement made fair work ; but it was evident that the work would have 
been much better and the draught lighter if the beams had been more rigid. 
Snoivden. No. 1180. — The peculiarity in this plough consists in the prin- 
cipal beam being of wood, G feet 8 inches long, 3j X 4 inches. The right-hand 
beam of iron can be expanded so as to vary the furrow from 7 to lOi inches. 
The stilts are iron, and the beam is braced with iron, so as to render it very 
strong. The Judges were unanimous in expressing disapproval of this mixture 
of wood and iron, which is doubtless used on account of lightness and rigidity, 
and it is a noticeable fact that this jilough sprang less than any other ; but in 
time the points of connection between the two materials will become loosened 
from the decay of the wood, and then the plough will lose its form and work. 
This plough has a very efficient lifting-api)aratus, consisting of a land-side wheel, 
■which slides on a bar so as to be placed farther or nearer the beam. On the 
other end of the bar and coming down behind the first plough is a skid, and on 
the land-side wheel and skid the plough is raised clear of the ground, the 
necessary leverage being obtained by a connecting-rod to the stilts. So perfectly 
balanced is the plough when supported as described, that it rides round at the 
land's-end, without the slightest assistance being necessary from the ploughmati. 
The friction-wheel is adjustable and bevelled, and can be raised and lowered 
three inches by a nut working in a slot on the mouldboard frame. The 
Judges considered this a well-made implement. Fig. 21 shows the plough 
in work ; a side elevation. Fig. 23 is a plan of the same, giving a better 
idea of the combination of wood and iron, and a general idea of the construc- 
tion. Figs. 22 and 24 give a side elevation and j^lan of article 1181, precisely 
similar in construction, only made entirely of iron. Fig. 25 is an enlarged plan 
showing the mechanism : J is a strong screw with double nuts, and a a are 
slots, by which the width of the furrow is adjusted ; c, the cross-bar to which
