Before passing the subject of physiology it is well to consider the meaning of the expression that this subject “_should be the basis of every educational effort_.” Text-book study of physiology, it is clear, can not cover this requirement. The fact is that _book-study_ is but a small part of Christian education. True education is life, and he who learns much must live much. The food eaten, the manner of clothing the body, the study, exercise, mental habits, physical habits, manual training, in fact, every phase of life is a part of the study of physiology and hygiene, and these subjects must one and all receive due consideration by the Christian educator. [Sidenote: Manual training and education] Manual training is becoming popular in many of our city schools, but the work offered in a Christian school will differ from that of the worldly school in this,—the latter is training the hand or the eye only, the former is building character by giving a trade that enables the student to be self-supporting and independent. In that the aims are different, the methods must differ, although the matter taught may in many cases be identical. [Sidenote: Healthful diet and dress] Healthful living is receiving attention in many schools. The Christian school, while teaching the same subject, will have as its object a preparation for eternal life. The subject, taught without faith, will bring only increased physical and mental activity. The spiritual nature can be reached alone by that education which is based on faith. [Sidenote: Need of books] Simply a casual investigation of the subject of Christian education reveals the need of books for the guidance of teachers who undertake to direct the growth of the child. With proper study-books, based upon the eternal principles of truth revealed in the Scriptures, the work which is now in its infancy would make much more rapid and substantial progress. [Sidenote: The home school] Parents who sense the responsibility resting upon them in the rearing of children for the kingdom of heaven are anxious to know when and where the principles of Christian education can be carried out. The beauty of the system is nowhere more vividly portrayed than in the recognition which it gives to the _home_ and the _duty of parents_ toward their children in the matter of education.
