The number of little books and pamphlets dealing with the question of the sexual enlightenment of the young--whether intended to be read by the young or offering guidance to mothers and teachers in the task of imparting knowledge--has become very large indeed during recent years in America, England, and especially Germany, where there has been of late an enormous production of such literature. The late Ben Elmy, writing under the pseudonym of "Ellis Ethelmer," published two booklets, _Baby Buds_, and _The Human Flower_ (issued by Mrs. Wolstenholme Elmy, Buxton House, Congleton), which state the facts in a simple and delicate manner, though the author was not a notably reliable guide on the scientific aspects of these questions. A charming conversation between a mother and child, from a French source, is reprinted by Edward Carpenter at the end of his _Love's Coming of Age. How We Are Born_, by Mrs. N.J. (apparently a Russian lady writing in English), prefaced by J.H. Badley, is satisfactory. Mention may also be made of _The Wonder of Life_, by Mary Tudor Pole. Margaret Morley's _Song of Life_, an American book, which I have not seen, has been highly praised. Most of these books are intended for quite young children, and while they explain more or less clearly the origin of babies, nearly always starting with the facts of plant life, they touch very slightly, if at all, on the relations of the sexes.
