For companion I should want a veteran of the war! Those marches put something into him I like. Even at this distance his mettle is but little softened. As soon as he gets warmed up it all comes back to him. He catches your step and away you go, a gay, adventurous, half predatory couple. How quickly he falls into the old ways of jest and anecdote and song! You may have known him for years without having heard him hum an air, or more than casually revert to the subject of his experience during the war. You have even questioned and cross-questioned him without firing the train you wished. But get him out on a vacation tramp, and you can walk it all out of him. By the camp-fire at night or swinging along the streams by day, song, anecdote, adventure, come to the surface, and you wonder how your companion has kept silent so long. It is another proof of how walking brings out the true character of a man. The devil never yet asked his victims to take a walk with him. You will not be long in finding your companion out. All disguises will fall away from him. As his pores open his character is laid bare. His deepest and most private self will come to the top. It matters little whom you ride with, so he be not a pickpocket; for both of you will, very likely, settle down closer and firmer in your reserve, shaken down like a measure of corn by the jolting as the journey proceeds. But walking is a more vital copartnership; the relation is a closer and more sympathetic one, and you do not feel like walking ten paces with a stranger without speaking to him. Hence the fastidiousness of the professional walker in choosing or admitting a companion, and hence the truth of a remark of Emerson that you will generally fare better to take your dog than to invite your neighbour. Your cur-dog is a true pedestrian, and your neighbour is very likely a small politician. The dog enters thoroughly into the spirit of the enterprise; he is not indifferent or preoccupied; he is constantly sniffing adventure, laps at every spring, looks upon every field and wood as a new world to be explored, is ever on some fresh trail, knows something important will happen a little farther on, gazes with the true wonder-seeing eyes, whatever the spot or whatever the road finds it good to be there--in short, is just that happy, delicious, excursive vagabond that touches one at so many points, and whose human prototype in a companion robs miles and leagues of half their power to fatigue.
