Another way in which the mystery of parenthood can be simply and comfortably taught is through the study of vegetable physiology. The fertilisation of the ovules by pollen which falls directly from the anthers on to the stigma can be used as a representation of similar facts in animal physiology. It is very desirable, however, that this study of the vegetable should succeed and not precede that of the domestic animals in the teaching of boys and girls. Viewed from this standpoint there is surely no difficulty to the parent in imparting to the child this necessary knowledge. We have to remember that children have to know the mysteries of life. They cannot live in the world without seeing the great drama constantly displayed to them in family life and in the lives of domesticated animals. They cannot read the literature of Greece and Rome, nay, they cannot study the Book of Books, without these facts being constantly brought to mind. A child's thirst for the interpretation of this knowledge is imperative and unsatiable--not from prurience nor from evil-mindedness, but in obedience to a law of our nature, the child demands this knowledge--and will get it. It is for fathers and mothers to say whether these sublime and beautiful mysteries shall be lovingly and reverently unveiled by themselves or whether the child's mind shall be poisoned and all beauty and reverence destroyed by depraved school-fellows and vulgar companions. In the hope of securing the purity, reverence and piety of our children, in the hope that they may grow up worthy of their high destiny, let us do what we may to keep their honour unsmirched, to preserve their innocence, and to lead them on from the unconscious goodness of childhood to the clear-eyed, fully conscious dignity of maturity, that our sons may grow up as young plants, and our daughters as the polished corners of the temple. PART II.: BOYS. BY F. ARTHUR SIBLY, M.A., LL.D. PREFACE TO THE SECOND EDITION. My contribution to this little book was originally intended for the eyes of parents, scoutmasters, and other adults. Since 1913, when the book was first published, it has been my privilege to receive from these so many letters of warm appreciation that it seems needless to retain the apologetic preface which I then wrote. The object which I had in view at that time was the hastening of a supremely important reform. I have to-day the very deep joy of knowing that my words have carried conviction to many adults and have given help to countless boys.
