Changing conditions of life, both social and economic, seem to call for a readjustment in our high-school procedure. Conceding the influence of colleges of education and normal schools inculcating better methods of teaching, there is much high-school teachers can do to determine career effectiveness of high-school graduates. This book is an appeal to the individual teacher, to make the most of themselves and of the opportunities to assist the high-school to attain the full fruition of its purposes; that education may have a larger content; and that society may become the beneficiary of high-school influences.
