animals. He has changed the character of the species. Through
taming, individuals of species naturally in conflict with man have
become accommodated to him. Eugenics may be regarded as a program of
biological adaptation of the human race in conscious realization of
social ideals. Education, on the other hand, represents a program of
accommodation or an organization, modification, and culture of original
traits.

Every society represents an organization of elements more or less
antagonistic to each other but united for the moment, at least, by an
arrangement which defines the reciprocal relations and respective
spheres of action of each. This accommodation, this _modus vivendi_, may
be relatively permanent as in a society constituted by castes, or quite
transitory as in societies made up of open classes. In either case, the
accommodation, while it is maintained, secures for the individual or for
the group a recognized status.

Accommodation is the natural issue of conflicts. In an accommodation the
antagonism of the hostile elements is, for the time being, regulated,
and conflict disappears as overt action, although it remains latent as a
potential force. With a change in the situation, the adjustment that had
hitherto successfully held in control the antagonistic forces fails.
There is confusion and unrest which may issue in open conflict.
Conflict, whether a war or a strike or a mere exchange of polite
innuendoes, invariably issues in a new accommodation or social order,
which in general involves a changed status in the relations among the
participants. It is only with assimilation that this antagonism, latent
in the organization of individuals or groups, is likely to be wholly
dissolved.

2. Classification of the Materials

The selections on accommodation in the materials are organized under the
following heads: (a) forms of accommodation; (b) subordination and
superordination; (c) conflict and accommodation; and (d)
competition, status, and social solidarity.

a) _Forms of accommodation._--There are many forms of accommodation.
One of the most subtle is that which in human geography is called
acclimatization, "accommodation to new climatic conditions." Recent
studies like those of Huntington in his "Climate and Civilization" have
emphasized the effects of climate upon human behavior. The selection
upon acclimatization by Brinton states the problems involved in the
adjustment of racial groups to different cli
