For mothers Comenius wrote a book, entitled the "School of Infancy." In England this book is scarcely known at all: in Bohemia it is a household treasure. Comenius regarded it as a work of first-rate importance. What use, he asked, were schemes of education if a good foundation were not first laid by the mother? For the first six years of his life, said Comenius, the child must be taught by his mother. If she did her work properly she could teach him many marvellous things. He would learn some physics by handling things; some optics by naming colours, light and darkness; some astronomy by studying the twinkling stars; some geography by trudging the neighbouring streets and hills; some chronology by learning the hours, the days and the months; some history by a chat on local events; some geometry by measuring things for himself; some statics by trying to balance his top; some mechanics by building his little toy-house; some dialectics by asking questions; some economics by observing his mother's skill as a housekeeper; and some music and poetry by singing psalms and hymns. As Comenius penned these ideal instructions, he must surely have known that nine mothers out of ten had neither the patience nor the skill to follow his method; and yet he insisted that, in some things, the mother had a clear course before her. His advice was remarkably sound. At what age, ask mothers, should the education of a child begin? It should begin, said Comenius, before the child is born. At that period in her life the expectant mother must be busy and cheerful, be moderate in her food, avoid all worry, and keep in constant touch with God by prayer; and thus the child will come into the world well equipped for the battle of life. She must, of course, nurse the child herself. She must feed him, when weaned, on plain and simple food. She must provide him with picture books; and, above all, she must teach him to be clean in his habits, to obey his superiors, to be truthful and polite, to bend the knee and fold his hands in prayer, and to remember that the God revealed in Christ was ever near at hand.
