This book aims to raise those problems which every teacher sooner or later faces, and it attempts to suggest an approach by way of solution which will insure at least some degree of growth towards efficiency. These chaptersoriginally were prepared for the course offered to teacher-trainers in the Summer School of the Brigham Young University, in 1920. The teachers in that course were an inspiration to the author and are responsible for many of the thoughts expressed in the pages of this book. The successful teacher ever views his calling as an opportunity not as an obligation. To associate with young people is a rare privilege; to teach them is an inspiration; to lead them into the glorious truths of the Gospel of Jesus Christ is heavenly joy itself. This little volume hopes to push open the door of opportunity a little wider, that more of that joy may be realized. Perchance, in heaven, one day to me Some blessed Saint will come and say, All hail, beloved; but for thee My soul to death had fallen a prey;And oh I what rapture in the thought. One soul to glory to have brought. Adam S. Bennion.
