Let me assure you in the most practical way that there are two sides to this child question. There is a sentimental side, than which there is no other so worthy; and there is a practical side, than which there is none so profitable. The best and most profitable service in the whole gamut of useful occupations that I know about is in learning to know children, and in connection with a Quarantine movement which is now started, and which aims to not let one of these wards of the Christ escape the best care known to Love and the Science of Child-Life. The crèche and the kindergarten and the manual training schools, and domestic training classes, as well as institutions similar to the "Holiday Home" across the Bay, have demonstrated within the past thirty years that fully ninety-eight per cent of the "Hopelessly Submerged Ten Per Cent" can be rescued after they have been warped by evil surroundings. What will not the same effort effect if directed toward prevention and protection, instead of being squandered in careless and soulless correction? Christ said: "And a little child shall lead them." Let us awake to the call. It is the way to Heaven; for, "_Of such_ is the Kingdom of Heaven." FIVE YEARS' CONFIRMATORY EVIDENCE The spirit of the preceding address to the good members of the Unity League organisation on the shores of beautiful Lake Geneva has been the inspiring motive of the quest for scientific endorsement of Economic Nutrition for the benefit of the present generation of children, and, incidentally, of their elders. In Economic Nutrition lies protection from sexual morbidity, alcoholic intemperance, bodily disease, savage passions and all the brood of evil contamination and temptation. In Economic Nutrition lie possibilities of physical and mental energy and optimistic happiness such as the world has not been accustomed to in the memory of history. Economic Nutrition is what children want to be taught with their first indelible impressions, and the present great movement of which this little book treats, for which it was first responsible, and for which it is republished in a new and extended edition, is expected to furnish authoritative knowledge relative to the most Economic Nutrition, so that mothers and kindergartners may meet the little waifs from the Creator on the threshold of this present life with words of wisdom and examples of sanitary perfection, instead of confronting them at once with the poison of ignorance relative to their most important concern,--their own Economic Nutrition. That the contentions uttered in "That Last Waif; or, Social Quarantine," referred to in the Lake Geneva Address, are reasonable is evidenced by the experience of Dr. and Mrs. Kellogg and their adopted family of twenty-four waifs, the acquaintance of which has since been made.
