524 Report on the Exhibition and Trial of Implements 
provement of these implements at the successive Meetings of the Society, 
will not look to the past without satisfaction, nor to the future without hope. 
For the lest Cultivator, Grubber, and Scarifier, a Prize of 51. 
Three implements were put in competition for this prize, viz. : — 
Mr.Bentall's "Broadshare Plough," Mr. Coleman's " Cultivator," and Messrs. 
Eansome's " Biddel's Wrought Iron Scarifier." 
They were all first tried with broad shares upon a piece of pastured seeds, 
as paring ploughs, and though the ground was hard and dry, and in a state 
more unfavourable than any farmer would select for the use of such imple- 
ments, the paring was well done, and proved that for paring stubble-ground 
they were all very effective implements. The second trial was with points, 
instead of shares, in cross-dragging seed land that had been once ploughed. 
The Judges were of opinion that for paring turf or stubbles only Mr. Bentall's 
implement deserved the high reputation it has obtained ; and as a cultivator 
for very strong lands, where great power was necessary, the implement of 
Messrs. Ransome would be most effective ; but as an implement combining the 
qualifications of cultivator, gi-ubber, and scarifier, which seems to have been 
the object of the Society in offering the prize, Mr. Coleman's was preferred, 
and to him the prize was awarded. 
The Judges highly commend Mr. Bentall's implement as a scarifier, and 
commend Messrs. Ransome's as a grubber, scarifier, and cultivator. 
Mr. //qpe's PloiKjh. — This plough was submitted for trial by the exhibitor 
as possessing an improvement over ordinary ploughs in having a bevel wheel 
attached, following in the furrow, by which the draught was said to be 
greatly lessened. 
The plough was tested by the Dynamometer with and without the wheel, 
and it did not appear that the wheel eftected any saving in draught. 
Cotyreave's Plough. — This implement, manufactured by Messrs. Ransome and 
Sims, was first exhibited at the Society's meeting at Lincoln ; on this occasion 
it was tried upon a field of seeds, the soil a strong and deep loam, with 
results that surprised and gratified all who saw it. 
The operation is threefold ; a furrow of 5 inches deep is first ploughed 
and turned in the ordinary way ; a second or trench furrow is then cut 5 
inches deep, inverted, and deposited on the top of the first, and at the bottom 
of the trench a sub-pulverizer loosens the soil to a further depth of 34 inches ; 
the effect of the whole upon a tolerably free soil is not only to plough 
and invert the land to a great depth, but thoroughly to pulverize it ; no 
trenching or double digging by manual labour could have done more than 
was done by this implement, and for preparing for planting or for root crops 
it is of great value. No prize being oflered, the Judges awarded to this 
implement a silver medal. 
Clod Crushers. — A medal was awarded to John Palmer of Stockton, for his 
"Patterson's Self-cleaning Clodcrusher ;" the adaptation of a series of eccen- 
trics upon the centre axle, which, in revolving, rub and clean each other, is 
very ingenious and an important improvement. 
A medal was also awarded to Mr. Crosskill for his self-cleaning clod 
crusher, which it is now impossible to choke under the most unfavourable 
circumstances. 
A Beauderk's Patent Plough and Suhsoiler, exhibited by Messrs. Ran- 
some, was submitted to trial. Its operation is that of a common plough 
with an Archimedian screw attached, which revolves in the bottom of the 
furrow, thus ploughing and subsoiling at the same time. It did not appear 
to the Judges to possess any special merit ; there was no excellence in the 
result, and no apparent economy in the means ; the operation of the subsoiler 
seemed to be detrimental to the free action of the plough, and imperfect and 
unsightly work was the result. Wherever subsoiling is desirable it would
