We all know how much we are ourselves benefited by associating habitually with persons of superior abilities. So it is in a still higher degree with children. There is something contagious in the fire of intellect. The human mind, as well as the human heart, has a wonderful power of assimilation. Every judicious parent will say: Let not my child be consigned to the care of an ill-informed, dull, spiritless teacher. Let it be his happy lot, if possible, to be under one who has some higher ambition than merely to go through a certain prescribed routine of duties and lessons; one whose face beams with intelligence and whose lips drop knowledge; one who can cultivate in him the disposition to inquire, by his own readiness and ability to answer childish inquiries; who can lead the inquiries of a child into proper channels, and train him to a correct mode of thinking by being himself familiar with the true logical process, by having himself a cultivated understanding. Such a teacher finds a pleasure in his task. He finds that he is not only teaching his pupils to read and to spell, to write and to cipher, but he is acquiring an ascendancy over them. He is exerting upon them a moral and intellectual power. He is leaving, upon a material far more precious than any coined in the Mint, the deep and inerasible impress of his own character. Let me repeat then, at the risk of becoming tiresome, what I hold to be an important and elementary truth, that the teacher should know very many things besides what he is required to teach. A good knowledge of history will enable him to invest the study of geography with new interest. Acquaintance with algebra will give a clearness to his perceptions, and consequently to his mode of inculcating the principles, of arithmetic. The ability to delineate off-hand with chalk or pencil the forms of objects, gives him an unlimited power of illustrating every subject, and of clothing even the dullest with interest. Familiarity with the principles of rhetoric and with the rules of criticism, gives at once elegance and ease to his language, and the means of more clearly detecting what is faulty in the language of others. A knowledge of Latin or of French, or of any language besides his own, throws upon his own language a light of which he before had no conception. It produces in his ideas of grammar and of language generally, a change somewhat like that which the anatomist experiences from the study of comparative anatomy. The student of the human frame finds many things that he cannot comprehend until he extends his inquiries to other tribes of animals; to the monkey, the ox, the reptile, the fish, and even to the insect world. So it is with language. We return from the study of a foreign language invariably with an increased knowledge of our own. We have made one step at least from the technicalities of particular rules towards the principles and truths of general grammar.
