Fig. 5.—Device for stacking Alfa’fa hay. 
Figure 5shows the device used for stacking alfalfa on 
the farm of Mr. A. B. Lyman, Excelsior, Minn. The upright 
piece is made to turn freely, and the pulley at the base is so 
placed that as the load is drawn up, the rope pulls the arm 
around so that the hay is deposited in the center of the 
stack. Alfal‘a seeds rather uncertainly; the second crop is 
usually better than the first for seed production. For seed 
it should be cut when the seed pods turn dark, and should 
be handled in the same way as is clover for seed. The yield 
is from two to four bushels per acre.
