will provide a more adequate sociology of subordination
and superordination. A survey of the present output of material upon the
nature and the effects of personal contacts reinforces the need for such
a fundamental study. The obsolete writings upon personal magnetism have
been replaced by the so-called "psychology of salesmanship," "scientific
methods of character reading," and "the psychology of leadership." The
wide sale of these books indicates the popular interest, quite as much
as the lack of any fundamental understanding of the technique of human
relations.

3. Accommodation Groups

The field of investigation available for the study of accommodation
groups and their relation to conflict groups may perhaps be best
illustrated by the table on page 722.

The existence of conflict groups like parties, sects, nationalities,
represents the area in any society of unstable equilibrium.
Accommodation groups, classes, castes, and denominations on the other
hand, represent in this same society the areas of stable equilibrium. A
boys' club carries on contests, under recognized rules, with similar
organizations. A denomination engages in fraternal rivalry with other
denominations for the advancement of common interests of the church
universal. A nation possesses status, rights, and responsibilities only
in a commonwealth of nations of which it is a member.

The works upon accommodation groups are concerned almost exclusively
with the principles, methods, and technique of organization. There are,
indeed, one or two important descriptive works upon secret organizations
in primitive and modern times. The books and articles, however, on
organized boys' groups deal with the plan of organization of Boy Scouts,
Boys' Brotherhood Republic, George Junior Republics, Knights of King
Arthur, and many other clubs of these types. They are not studies of
natural groups.

The comparative study of social classes and vocational groups is an
unworked field. The differentiation of social types, especially in ur
