e alsike. The
rule is to mix alsike with the red at the rate of one or two bushels of
the former to six bushels of the latter. As the seed of the alsike is
hardly half as large as that of the red, the proportion in the mixture
is greater than some farmers realize. The practice is an excellent one
where the red will not grow, and the alsike adds fertility, but when
the soil has been made alkaline, the red clover should have nearly all
the room. Alsike is a heavy producer of seed.

Crimson Clover.--Wherever crimson clover is sufficiently hardy to
withstand the winter, as in Delaware and New Jersey, it is a valuable
aid in maintaining and increasing soil fertility. It is a winter
annual, like winter wheat, and should be seeded in the latter half of
summer, according to latitude. It comes into bloom in late spring. The
plant has a tap-root of good length, but in total weight of roots is
much inferior to the red. This clover, however, compares favorably with
red clover in the total amount of nitrogen added to the soil by the
entire plant when grown under favorable conditions. It is peculiarly
fitted for a cover crop in orchards and wherever spring crops are
removed as early as August, or a seeding can be made in them, as is the
case with corn. Even when winter kills the plants, a successful fall
growth is highly profitable, adding more nitrogen before winter than
red clover seeded at the same time. Where the plants do not
winter-kill, they are plowed down for green manure when in bloom in
May, or earlier in the spring to save soil moisture and permit early
planting, although a good hay for livestock can be made, and the yield
is about the same as that of the first crop of red clover.

In the northern states a large amount of money has been wasted in
experimental seedings with crimson clover, and it is only in
exceptional cases that it continues to be grown. There is reason to
believe that many of these failures were due to lack of soil
inoculation. The Pennsylvania experiment station is located in a
mountain valley where winters are severe. Crimson clover is under test
with other cover crops for an experimental orchard, and success with it
has increased as the soil has become fully inoculated. This view is
supported by the experience of various growers in the North, and while
crimson clover can never make the success in a cold climate that it
does in Delaware, there is a much wider field of usefulness for it than
is now oc
