Report on Implements at Preston. 
three-horse set can be re-combined to serve for two-horse or for 
four-horse work, and thus reduce the farmer's outlay.

Vipan and Hcadley, No. 4131. Four trees are here arranged 
like Erenton's and Kell's ; ash, with iron links, like those shown 
in Class VI. The equalising tree was curved, a form not gene- 
rally to be recommended in wood, unless it is specially picked 
out, as this one was, with a natural curve in the grain. 
The prize in this class was awarded to ^lessrs. Ransomes,^ 
Sims, and Jefferies, No. 4340. 
In Class VI., for Four-horse Whippletrees, two of the exhi- 
bitors drove their horses abreast, a mode of driving that cannot 
be adopted in ploughing, and that requires hardly any ingenuity 
in the arrangement of the whippletrees. We will take these two 
entries first. Wm. Brenton employed one long tubular iron 
tree, and attached to each end of it one of his sets of two-horse 
whippletrees, as used by him in Class IV. It will be noticed 
that this set of seven iron trees is among the heaviest in the class. 
Davey, Sleep, Sf Co., No. 412, dispensed with intermediate 
pomel-trees, the whippletree for each horse being directly 
attached to the one long tree. These five trees were all of 
their hollow steel pattern ; the long tree is very little longer 
than the tree they used in Class V. for three horses, conse- 
quently the minor trees overlapped one another considerably. 
This arrangement does not provide sufficiently for the equalisa- 
tion of the draughts of the different horses. 
Three competitors arranged their horses in double sets. In the 
first of Thos. Corbett's entries. No. 2440 (Fig. 10), it will be seen 
that we have first a stout ash pomel-tree, and at either end of it 
an ingenious arrangement of double compensating levers and 
trees of flat steel. An ordinary ploughman might easily get con- 
fused in trying to carry out the peculiar arrangement of these 
traces ; it is a pity that the result of so much contrivance 
should be that each horse is subjected to a draught continually 
shifting from shoulder to shoulder, his traces being attached
