DESCRIPTION OF PLATES. 



Plate I. Fig. 1. — Mast and boom stacker, with six-tined Jackpoii fork. The mast 

 is held in place by guy ropes from *the top. Leading to the right may be seen the rope 

 to which is attached a team of horses. The base of the derrick is in the form of sled 

 runners, so that the whole may be drawn along the stack ])y attaching a team. Fig. 

 2. — A cable derrick, provided with a grapple fork. The cable is supported by poles 

 at the ends, and these in turn by guy ropes. 



Plate II. Fig. 1. — A derrick stacker, with six-tined Jackson or California fork. 

 The derrick is substantial, and guy ropes are not necessary. Stakes driven into the 

 ground around the base hold the derrick in place. Fig. 2. — The same derrick, show- 

 ing details. It will be observed that from the peculiar attachment of the ropes, the 

 hay is swung over the stack Avhile it is being lifted from the wagon. 



Plate III. Types of derrick stackers. Fig. 1. — Derrick built on wheels and sym- 

 metrically braced. Fig. 2. — Derrick with revolving pole. In both forms the central 

 pole rotates in sockets. The ropes are not attached to this derrick. 



Plate IV. Fig. 1. — A common type of hayrack. Fig. 2. — A pole stacker, with four- 

 tined Jackson fork. The angle of the pole is regulated by a short beam. This is 

 often replaced by a chain or rope. The derrick leans toward the stack sufficiently to 

 swing the fork load of hay into position, when it is elevated. 



Plate V. — Types of racks in common use for feeding alfalfa to cattle. Fig. 1. — 

 Lattice rack. Fig. 2.— Box rack. 



Plate VI.— Types of racks 'for feeding alfalfa to sheep. These racks are longer 

 than those intended for cattle. Fig. 1. — Lattice rack. Fig. 2. —Box rack. 



Plate VII. Fig. 1. — Hay press, for baling grain hay, San Jose, Cal. Five men and 

 three horses are employed; one man and horse drag the hay from the stack to the 

 baler, with a four-tined Jackson fork; one man drives a team attached to the horse- 

 power; two men pitch the hay into the baler; one man works the press and weighs 

 the bales. Average time, three minutes to the bale. Weight of bales, about 210 

 pounds. Bales tied with rope. Fig. 2. — Field of brome grass at the Kansas Experi-
