of an excellent pattern, the oak carriage-frame is of great strength ; the worm 
and cog-wheel for raising the trough and the joint of the shaft iVom the horse- 
gear are furnished with iron caps to prevent hay or straw from catching in 
them. The teeth are attached to the ralcc-lieads by nuts and screws, and are 
forged with a collar that helps to keep tlicra firm. The point most open to 
criticism in the machine is the size of the pulleys on which the wire ropes are 
wound, their diameter at the bottom of the groove is only 7^ inches ; it is 
not well to bend wire rope so sharjily, and we would recommend that the 
pulleys should be made larger. With this single minor exception, the 
machine is of admirable construction and workmanship. Its price contrasts 
very favourably with those of many machines of inferior make.
