_Fifth._ By omitting the period of exploration, we have been able to
enlarge the treatment of our own time. We have given special attention
to the history of those current questions which must form the subject
matter of sound instruction in citizenship.

_Sixth._ We have borne in mind that America, with all her unique
characteristics, is a part of a general civilization. Accordingly we
have given diplomacy, foreign affairs, world relations, and the
reciprocal influences of nations their appropriate place.

_Seventh._ We have deliberately aimed at standards of maturity. The
study of a mere narrative calls mainly for the use of the memory. We
have aimed to stimulate habits of analysis, comparison, association,
reflection, and generalization--habits calculated to enlarge as well as
inform the mind. We have been at great pains to make our text clear,
simple, and direct; but we have earnestly sought to stretch the
intellects of our readers--to put them upon their mettle. Most of them
will receive the last of their formal instruction in the high school.
The world will soon expect maturity from them. Their achievements will
depend upon the possession of other powers than memory alone. The
effectiveness of their citizenship in our republic will be measured by
the excellence of their judgment as well as the fullness of their
information.
