Report of the Trial of Cultivators, Clod Crushers, [Plain Rollers, and 
Harrows. 
We selected for trial 22 cultivators, 8 clod crashers, 17 rollers, and 41 sets of 
harrows, in all 88 implements ; each of these had to ho conveyed a distance of 
four miles to the trial-ground, where many of them were tried in two and 
several in three different fields. The time thus allowed for testing the merits 
of each implement was consequently very limited. The trials may thus have 
appeared less satisfactory than if more time could have heen allowed the 
exhibitors to adjust and work their respective implements. 
Speaking generally of the implements which came under our notice, we feel 
that great praise is due to the exhibitors for the great improvements which 
have been accomplished in their manufacture, particularly in the quality of 
the materials used, and the hardening the points, &c, most exposed to 
wear and tear. Although many of the attempts at novelty of construction 
may not have heen so successful as could have been desired,' the exhibitors 
show a commendable spirit in endeavouring to give practical effect to any new 
conception or suggestion. 
The first trials coming under our consideration were the 
Cultivators. 
Out of the 22 selected, 13 were tried with hroadshares on a piece of foul 
land rendered very hard by the dry weather. Under this severe trial many of 
them made very fair work. These were again tried with points, along with the 
remaining 9, working as grubbers or scarifiers on a piece of clean fallow. Hero 
they nearly all worked well. 
The construction of these implements was very varied, no two of them being 
alike, so likewise was the force required to work them, which ranged from 1 to 
0 horse-power. This made it a difficult task to decide on their merits ; but 
considering that a plain, strong, simple, and well-manufactured implement was 
the " desideratum," we awarded a prize of 122. to Mr. Bentall, 101. to Messrs. 
Coleman and Morton, and 81. to Mr. Charles Clay. We also highly commended 
Messrs. Coleman and Morton's cultivator for large occupiers ; and commended 
Messrs. Corhett and Sons' implement. 
Clod Crushers. 
Eight were selected for trial in this class, being worked on a piece of rough 
fallow well suited for the purpose. Several of them made excellent work, and 
after testing the draught of four of the best of them by the dynamometer, we 
awarded a prize of 91. to the Beverley Iron and Waggon Company, 61. to 
Messrs. Crosskill and Sons, and 51. to Mr. Cambridge ; we also highly com- 
mended Messrs. Amies and Barfords implement. 
Hollers. 
There were 17 selected for competition, most of which showed great im- 
provement in their construction, from the judicious substitution of wrought 
for cast iron both in the cylinders and frames ; and also from their being made 
up of segments instead of one whole cylinder, a change which enables them to 
turn more easily, and to work much more effectually where the surface is un- 
even. Improvements were also made in the mode of fixing the bearings, so 
that they could be removed without the necessity of taking the frames to 
pieces. 
We considered the Ballasting Rollers, exhibited by Messrs. Amies and Barford, 
very superior. They were entirely of wrought iron, and were composed of 2 
water-tight cylinders which can be loaded at pleasure — thus securing a light- 
and heavy roller in one implement. Our instructions only allowed us 101. in 
this class, which we apportioned by awarding a prize of 11. to Messrs. Amies, 
and Barford, and 31. to the Beverley Iron and Waggon Company. We also
