from year to year. Indiana and Ohio are great clover States,
and the same is true of much of Illinois and Iowa; but southward in
these States there is some hazard to the young plants from drought and
heat in summer, and to an occasional frost in winter when the ground is
bare.

East of the States named, it would probably be correct to say that the
highest adaptation is found in New York and Pennsylvania, particularly
the former, in many parts of which excellent crops are grown. In various
parts of the New England States good crops may also be grown. Much of
the soil in these is not sufficiently fertile to grow clover as it can
be grown in the more Central States. The same is true of the States of
Delaware, Maryland and Eastern Virginia, east of the Rocky Mountains,
south from the Canadian boundary and west from Minnesota, Iowa and
Missouri, but little success has heretofore attended the efforts to grow
medium red clover. This statement does not apply equally to Eastern
Nebraska and Kansas. Usually the climate is not moist enough in summer,
the sweep of the cold winds is too great in winter, the snowfall is
usually insufficient to protect the plants, and it may be also that the
requisite bacteria is lacking in the soil. Sometime, however, these
adverse conditions may in part be overcome by man's resourcefulness. In
parts of States that lie south of the 37th parallel, it may be found
profitable to grow crops of medium red clover; but in these, other
legumes, as crimson clover, cow peas and soy beans, will probably
furnish food more reliably and more cheaply.

In Canada the highest all-round adaptation for clover is in Ontario and
Quebec, unless it be the mountain valleys and tide lands of British
Columbia. Because of the high adaptation in the soil of the two
provinces first named, and the plentifulness of the snowfall, clover in
these is one of the surest of the crops grown. The maritime provinces of
New Brunswick, Nova Scotia and Prince Edward's Island, particularly the
former, have soils a little too hungry to produce the highest returns in
clover. On the open prairies between Ontario and the Rocky Mountains,
not much success has attended the attempts to grow any kind of clover,
owing probably to present uncongeniality in soils and more especially in
climatic conditions. However, there are good reasons for believing that
with the introduction of hardy varieties and through the use of Northern
grown seed, an inoculated
