There is, indeed, great difference between tween the mind of children and of adults, and literature should respect and provide for this difference,--although it is true that the best books please and edify both, and the nursery and parlour can meet in pretty full fellowship over "AEsop's Fables," "Robinson Crusoe," and "Pilgrim's Progress," if not over the "Vicar of Wakefield" and Edgeworth's "Popular Tales." The great distinction between juvenile and adult literature is a very obvious and natural one. Not to discuss now the absence of business cares and ambition, children, in their normal, healthful state, know nothing of love as a passion, whilst it is the conspicuous feature of adult society, and the motive of all romances for readers of advanced years, and especially for all who have just passed into the charmed borders of adult life. I do not say, indeed, that children are to know nothing of love, or that it should be shut out of their habitual reading; for love is a part of human life, and is organized into manners and institutions, and sanctioned and exalted by religion. As a fact, and as sustaining great practical relations, love is to be treated freely in juvenile literature, but not as a passion. Every boy and girl who reads the Prayer-Book, and hears every-day talk, and sees what is going on in the world, knows that men and women marry, and young people fall in love and are engaged. This is all well, and children's stories may tell freely whatever illustrates the home usages and social customs of the people; but the more the love senses and passions are left to sleep in their sacred and innocent reserve within their mystic cells, so much the better for the child whilst a child, and so much the better for the youth when no more a child, and Nature betrays her great secret, and the charming hallucinations of romance open their fascinations and call for the sober counsels of wisdom and kindness.
