DESCRIPTION OF PLATES. 
Puatel. Fig. 1.—Mast and boom stacker, with six-tined Jackson 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 attacned a team of horses. The base of the derrick is in the form ofsled 
runners, so that the whole may be drawn along the stack by 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. 
Prate ll. 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 while it is being lifted from the wagon. 
PuatE 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. 
PuateE TV. 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. 
Piate V.—Types of racks in common use for feeding alfalfa to cattle. Fig. 1.— 
Lattice rack. Fig. 2.—Box rack. 
Piate 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. 
Puate VII. Fig. 1.—Hay press, for baling grain hay, San José, 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- 
ment Station, Manhattan, Kans. A seven-year-old boy stands in the grass.
