But so blinded, on these matters, is our accustomed mode of thought, that Mr. Beecher's recent lecture on the Laws of Nature has been met with strong objections from a portion of the religious press. These newspapers agree in asserting that admiration of physical strength belonged to the barbarous ages of the world. So it certainly did, and so much the better for those ages. They had that one merit, at least; and so surely as an exclusively intellectual civilization ignored it, the arm of some robust barbarian prostrated that civilization at last. What Sismondi says of courage is preëminently true of that bodily vigor which it usually presupposes: that, although it is by no means the first of virtues, its loss is more fatal than that of all others. "Were it possible to unite the advantages of a perfect government with the cowardice of a whole people, those advantages would be utterly valueless, since they would be utterly without security." Physical health is a necessary condition of all permanent success. To the American people it has a stupendous importance because it is the only attribute of power in which they are losing ground. Guaranty us against physical degeneracy, and we can risk all other perils,--financial crises, Slavery, Romanism, Mormonism, Border Ruffians, and New York assassins; "domestic malice, foreign levy, nothing" can daunt us. Guaranty us health, and Mrs. Stowe cannot frighten us with all the prophecies of Dred; but when her sister Catherine informs us that in all the vast female acquaintance of the Beecher family there are not a dozen healthy women, we confess ourselves a little tempted to despair of the republic. The one drawback to satisfaction in our Public-School System is the physical weakness which it reveals and helps to perpetuate. One seldom notices a ruddy face in the school-room, without tracing it back to a Transatlantic origin. The teacher of a large school in Canada went so far as to declare to us, that she could recognize the children born this side the line by their invariable appearance of ill-health joined with intellectual precocity,--stamina wanting, and the place supplied by equations. Look at a class of boys or girls in our Grammar Schools; a glance along the line of their backs affords a study of geometrical curves. You almost long to reverse the position of their heads, as Dante has those of the false prophets, and thus improve their figures; the rounded shoulders affording a vigorous chest, and the hollow chest an excellent back.
