effected as follows : Two ropes are attached to the whiffle- 

 tree, one, a strong one, to elevate the hay, running on the 

 pulleys at B, C, and D ; and the other, a smaller one, pass- 

 ing the swivel pulley at ^1, on the 

 end of the lever j5, extending from 

 the foot of the upright shaft. This 

 cord then passes up and over a 

 pulley above the weight JS. The 

 weight is about four pounds, and is 

 attached to the end of the smaller 

 cord. At the same time that the 

 horse, in drawing, elevates the fork 

 with its load of hay, the weight 

 E is raised until it strikes the pul- 

 ley, when the power 

 of the horse becomes 

 applied to the end of 

 the lever JB, causing 

 it to revolve, and 

 swing the hay over 

 the stack. As the

horse backs, the weight drops again to the ground, 

 taking up the slack rope from under the horse's feet, and 

 the weight of the fork causes the arm of the derrick to 

 revolve back over the load. The intended height for 

 raising the hay, before swinging, is regulated by length- 

 ening or shortening the smaller cord, as the arm will not 

 revolve until the weight strikes the pulley under the 

 head block. T. G. & M. W. Palmer, of Chicago, OAvn

Fig. 208 shows the manner in which Raymond's Ele- 

 vator is mounted for stack building. These poles need 

 not be so heavy as when three poles alone are used. They 

 are kept from being drawn over towards each other in
