The human body is a steed that goes freest and longest under a light rider, and the lightest of all riders is a cheerful heart. Your sad, or morose, or embittered, or preoccupied heart settles heavily into the saddle, and the poor beast, the body, breaks down the first mile. Indeed, the heaviest thing in the world is a heavy heart. Next to that, the most burdensome to the walker is a heart not in perfect sympathy and accord with the body,--a reluctant or unwilling heart. The horse and rider must not only both be willing to go the same way, but the rider must lead the way and infuse his own lightness and eagerness into the steed. Herein is no doubt our trouble, and one reason of the decay of the noble art in this country. We are unwilling walkers. We are not innocent and simple-hearted enough to enjoy a walk. We have fallen from that state of grace which capacity to enjoy a walk implies. It cannot be said that as a people we are so positively sad, or morose, or melancholic as that we are vacant of that sportiveness and surplusage of animal spirits that characterized our ancestors, and that springs from full and harmonious life,--a sound heart in accord with a sound body. A man must invest himself near at hand and in common things, and be content with a steady and moderate return, if he would know the blessedness of a cheerful heart and the sweetness of a walk over the round earth. This is a lesson the American has yet to learn,--capability of amusement on a low key. He expects rapid and extraordinary returns. He would make the very elemental laws pay usury. He has nothing to invest in a walk; it is too slow, too cheap. We crave the astonishing, the exciting, the far away, and do not know the highways of the gods when we see them,--always a sign of the decay of the faith and simplicity of man. If I say to my neighbor, "Come with me, I have great wonders to show you," he pricks up his ears and comes forthwith; but when I take him on the hills under the full blaze of the sun, or along the country road, our footsteps lighted by the moon and stars, and say to him, "Behold, these are the wonders, these are the circuits of the gods, this we now tread is a morning star," he feels defrauded, and as if I had played him a trick. And yet nothing less than dilatation and enthusiasm like this is the badge of the master walker. If we are not sad, we are careworn, hurried, discontented, mortgaging the present for the promise of the future. If we take a walk, it is as we take a prescription, with about the same relish and with about the same purpose; and the more the fatigue, the greater our faith in the virtue of the medicine.
