For one of the chief ex- penditures of money is for food; one of the chief features of the home is the social meal ; one of the most important elements in the care of the child is its nutrition. It is perhaps hardly going too far to say that the right choice of food is basal to all physical, moral, and spiritual growth and usefulness. CONTENTS PAOB CHAPTER . I.
