and has unloaded a ton of hay in about three mmutes; 

 and over a beam twenty-two feet high, under a low rafter, 

 in about nine minutes. 



In using horse forks, as already stated, their operation 

 is much facilitated by providing a board slide, to be 

 placed vertically against the face of the mow, or bay, on 

 which the hay moves upward. In pitching into a win- 

 dow, the bottom of this board slide should be placed out 

 a few feet from the building, and the top should rest on 

 the base of the window. When convenient, the back 

 end of the wagon load should be placed towards the win- 

 dow. There is no limit to the height at which the pitch- 

 ing may be easily performed giving the use of the 

 horse-fork a great advantage over hand pitching; and 

 barns, with high posts, may be built for the storage of 

 hay. 



Other forms have been adopted for pitching under roofs, 

 by using shorter handles. One of the best is Palmer's
