But the mother, who knows better, will find a hundred opportunities to teach geography by the way: a duck-pond is a lake or an inland sea; any brooklet will serve to illustrate the great rivers of the world; a hillock grows into a mountain – an Alpine system; a hazel-copse suggests the mighty forests of the Amazon; a reedy swamp, the rice-fields of China; a meadow, the boundless prairies of the West; the pretty purple flowers of the common mallow is a text whereon to hang the cotton-fields of the Southern States: indeed, the whole field of pictorial geography – maps may wait until by-and-by – may be covered in this way.
