548 Report of the Trials of Ploughs, Harrows, §-c, at Hull. 
character of the implement. A portion of the vetch stubble 
being at liberty was set out into plots, and here the ploughs of the 
following makers were tried, viz., Messrs. Ball, Corbett, Murray, 
Perkins, and Snowden ; and each implement, after executing 
its allotted portion, was removed to the Field No. 4, where the 
Dynamometer was worked by means of one of Fisken's light- 
rope Steam Cultivating Apparatus, which, from its steadiness of 
motion, and facilities for throwing in and out of gear at the 
travelling windlasses perfectly independent of the engine, was 
well qualified for the work, and infinitely superior to horse- 
power, which was formerly used. The third column gives the 
results of the Dynamometer-tests. 
The First Prize of lOZ. was awarded to G. W. Murray and Co., 
Banff, N.B., for Article No. 3501 ; and the Second Prize of 5Z. 
to J. D. Snowden, Doncaster, for Article No. 1180. 
Class 6. — Double-furrow Ploughs not exceeding 5 cwt. 
This class was for general-purpose ploughs, to be tested under 
the following conditions : to the depth of from 4 to 7 inches, on 
light and mixed land as far as practicable ; the extreme length 
from point of share to end of breast not to exceed 4^ feet. 
Eight entries were reduced to 6, by the withdrawal of Hodgson 
and the non-appearance of Lewin. In some cases the imple- 
ments exhibited, being exactly similar in construction to, only 
stronger than, those already described in Class 5, will .not re- 
quire more than a passing notice ; I shall therefore direct atten- 
tion chiefly to such as possess different arrangements. Both 
trials took place in Field No. 5. 
J. P. Fison. No. 2997. — This implement is composed of parallel beams of 
■wrought iron, strongly connected by bolts. The draught is from a bolt about 
the centre of the plough. The novelty consists in a combined lifting and steerage 
apparatus fixed in front, illustrations of which are attempted in Figs. 27 and 28 
(pp. 549 and 550). The raising part consists of a revolving screw with a small 
wooden roller at the end ; as this is lowered, the front part of the frame is raised 
out of the ground sufSciently for the shares to clear, and thus the plough is carried 
round, taking a bearing on the wooden roller in front, and on the friction-wheel 
behind. There are, however, serious disadvantages in the arrangement : first, 
it" requires some exertion on the part of the attendant to turn the winch-handle 
fixed between the stilts sufSciently to raise the frame, and again to lower it 
when the plough has been turned ; secondly, the base is too narrow to allow of 
the implement turning without being held up by the attendant, and we much 
question if in practice he would take the trouble to work the winch at all. 
The steerage is sensitive, although arrived at by greater complication than is 
necessary. The figures represent a side elevation (Fig. 27) and plan (Fig. 28) 
of the front portion ; and a detached central section of the socket through 
which the revolving screw passes is shown in Fig. 29 ; the wooden roller is not
