prepared his "Introduction to the Science of Government." This work soon
attained considerable popularity, both as a class book in schools, and
as a book for private reading and reference for adults. Not being
deemed, however, sufficiently _elementary_ for the children and youth
in most of our common schools, another work, entitled, "_First Lessons
in Civil Government_," was written to meet the capacities of younger or
less advanced scholars than those for whom the previous work was
designed.

The favorable reception of these works by the public, and the assurances
of their usefulness to thousands who have studied them, are to the
author a source of high gratification, and an ample reward for many
years of arduous labor. The value of these works has, however, been in a
measure impaired by changes in the government and laws since the time of
their first publication. The latter, especially, descending so minutely
into the details of the government of the state for which alone it is
intended, requires frequent revisions.

It has occurred to the author that a new work, more permanent in the
character of its matter, and adapted for use in all the states, is
demanded to supply the deficiency in the present course of education.
Stimulated by a desire to bear some part in laying a solid foundation
for our republican institutions, and encouraged by the success of his
former labors in this department of education, he has, after a
suspension of several years, resumed his efforts in this enterprise, in
the hope that, with the coöperation of teachers, and those having
official supervision of the schools, it may be carried forward to an
early consummation; when the principles of government shall be made a
subject of regular study in the schools, and the elements of a sound
political education shall be accessible to the mass of American youth.
