As young as nine years of age, a child is eagerly inquisitive as to what has taken place in the ages past and readily grasps a concept of World History. Therefore, for many years Calvert School nine-year-old pupils have been taught World History in spite of academic and parental skepticism and antagonism. But I have watched the gradual drift toward adoption of this plan of history teaching, and with it an ever-increasing demand for a text-book of general history for young children. I have found, however, that all existing text-books have to be largely abridged and also supplemented by a running explanation and comment, to make them intelligible to the young child.
