from drouth than the States farther east, so that millet 
has come to be relied on there very largely. If a crop 
of winter wheat is winter-killed, or even a spring- 
planted crop, such as corn, fails because of unfavorable 
weather after planting, the land may be sown to millet 
after it is too late to plant other crops. Having 
learned the peculiarities of the crop, farmers grow it in 
that section very generally, even in years when it is 
not needed as a catch crop. From Illinois eastward it 
is more distinctly a catch crop, and is not very gener- 
ally sown except in case of a shortage of other hay 
crops. 
Millet probably has a larger field of usefulness in 
the Eastern States than has heretofore been accorded 
it. In most of these States it is customary to grow 
only one crop a year on a given field. But it is pos- 
sible to grow a winter crop of rye hay and a summer 
crop of millet in most parts of the East, and both of 
these crops make good hay if properly handled. On 
farms where all the crops are fed, particularly on those 
which grow only the roughage and buy their grain, 
and therefore have an abundance of manure, and on 
which, in consequence, the soil does not particularly 
need the influence of leguminous crops, the above 
double-cropping system on a portion of the land is en- 
tirely rational. A few of the best farmers in the East 
practice this method on some fields. How far cow- 
peas will replace millet in this réle cannot be stated. 
They are coming into prominence for this purpose in 
the North and East. In good seasons the cow-pea 
yields fine crops of hay, but millet has the advantage 
of being somewhat drouth-resistant. On farms not
