yellow clover (_Medicago
lupulina_), Sand Lucerne (_Medicago media_), and a newly introduced
variety of Japanese clover (_Lespedeza bicolor_). These may prove more
or less valuable to the agriculture of the United States when they have
been duly tested, a work which as yet has been done only in the most
limited way. The latter include Florida clover (_Desmodium tortuosum_),
more frequently called Beggar Weed, Buffalo clover (_Trifolium
reflexum_), and Seaside clover (_Trifolium invulneratum_). These may be
worthy of some attention in limited areas where the conditions are
favorable, but it is not likely that they will ever be very generally
grown. They are dwelt upon rather to show their small economic
importance and with a view to prevent needless experimentation with
plants possessed of so little real merit.

CHAPTER II

SOME GENERAL PRINCIPLES WHICH APPLY TO THE GROWING OF CLOVERS

In growing clovers, as in growing other crops of the same species, which
embrace several varieties, certain features of management will apply
more or less to all of these in common. It will be the aim to point out
the chief of these in the present chapter.

=Adaptation in Clovers.=--Adaptation in the varieties of clover
considered will be more fully given when discussing these individually,
but enough will be said here to facilitate comparisons. Clover in one or
the other of its varieties can be grown in almost all parts of the
United States and Canada. Speaking in a general way, the medium and
mammoth varieties can be grown at their best between parallels 37 deg. and
49 deg. north latitude. Alfalfa has special adaptation for mountain valleys
of the entire West, but it will also grow in good form in parts of all,
or nearly all, the other States. Alsike clover grows in about the same
areas as the common and mammoth varieties, but it may also be grown
further North, owing to its greater hardihood. Crimson clover has
highest adaptation to the States east of the Allegheny Mountains and
west of the Cascades, but will also grow in the more Central States
south, in which moisture is abundant. Small white clover will grow in
any part of the United States or Canada in which moisture is
sufficiently present. Japan and burr clover grow best south of parallel
37 deg. and east of longitude 98 deg.. Sweet clover will grow in all the States
and provinces of the United States and Canada, but has highest
adaptation for the Central and Southern
