458 Report on the Trials of Implements at Cardiff. 
To use the implement, two rick-i3oles must be fixed firmly in the ground, 
and well stayed by guy ropes, one pole at the end of the stack, the other at a 
sufficient distance to allow the waggons to be unloaded midway between the 
two. One of the pulleys must be fastened at the top and another at the bottom 
of the pole furthest from the stack. A rope of one inch diameter is then passed 
through these pulleys, then through the swivel-hook pulley which is to carry 
the fork, and is stretched across to the other pole, to which it is fastened at a 
lower level than the pulley on the other pole, so that when tight it inclines 
towards the stack. A trace horse is attached to a whippletree at the other 
end of the rope.

In unloading the hay or loose corn, the sliding pulley is drawn down to the 
top of the load ; the man using the fork presses it into the hay as far as pos- 
sible by the lever A (Fig. 27) ; the lever is then brought into a perpendicular 
position, so that the point of the fork forms a right angle, B ; the fork is 
hooked to the pulley, and the horse being started the hay is raised, the pulley 
then slides along the rope to the stack. As soon as it reaches the desired spot 
the hand cord attached to the small eccentric lever must be pulled and the 
hay will bo discharged upon the stack. Although quite unfitted to elevate 
loose clover-haulm, this small and cheap implement is coming into much use 
in this country, and has had a very large sale in America, 15,000 having been 
reported as sold in one year in the United States. 
No. 5738. W. T. 11 right. For this and the next implement'only one rick-pole 
is re(iuired, held in position by 3 guy ropes. This pole carries a boom which is 
free to move round it, and which can be adjusted to any height by means of 
a rope passing through a pulley at the top of the pole. Upon the boom 
are two pulleys, as shown in the sketch, Fig. 28. The fork is suspended upon 
a rope, which passes over these pulleys round another pulley fixed near 
the bottom of the pole, and is then attached to the horse. The fork is double, 
formed of two curved three-pronged forks turned towards each other and 
fastened in the centre like a pair of scissors. The extremities of the handles are 
attached to two links, and these again are attached at their upper ends to a ring 
through which the elevating rope passes to the centre of the scissors or crab. 
The man who fills the fork on the cart holds a guide rope in his hand, by which
