Just to take a walk with your dog may be a revelation to you, as most simple matters are when you dare to view them for yourself without prejudice. In fact, what is any revelation or discovery but seeing things as they are? This daily walk over familiar ground, which bores you because you must take it for exercise, leaving out of it the fun which is the essential element of any exercise, is to your dog another joyous and expectant exploration of the Indes. He explored the same ground yesterday, to be sure, but all sorts of revolutions and migrations take place overnight; and if he be a real dog, not a spoiled pet, he will uncover more surprises on the familiar road than you uncover in the morning newspaper. Follow him sympathetically as he finds endlessly interesting things where you find little but boredom, and you may learn that there are three marked differences between you and a normal animal: first, that he keeps the spirit of play, which you have well-nigh lost; second, that he lives in his sensations and is happy, while you dwell mostly in your thoughts and postpone happiness for the future; and third, that he is alive now, every moment, and you used to be alive the day before yesterday.

In all this you are simply typical of our unnatural civilization, which begins to enumerate or [[41]]describe us as so many thousand “souls,” doubtless because every single body of us is moribund or asleep. Consider our noses, for example. They are the seat of a wonderful faculty, more dependable than sight or hearing; they are capable of giving us sensations more varied than those of color, and almost as enjoyable as those of harmony; they can be easily trained so as to recognize every tree and plant and growing thing by its delicate fragrance; they would add greatly to our safety and convenience, as well as to our enjoyment, did we use them as nature intended; yet so thoroughly neglected are they, as a rule, that it takes a burning rag or a jet of escaping coal-gas to rouse them to the immense and varied world of odors in which an animal lives continually.

At present I am the alleged owner of a young setter, Rab, who has reached the stage of development when he thinks he owns me. For after you have properly trained a dog, there comes a brief time when he discovers with joy that he can make you do things for him; and then he is like a child who discovers that he can make you talk (that is, show some sign of life) by asking you questions. And this young setter has, I am convinced, a very low opinion of human aliveness, since there is never a day when he does not give me a hint that he considers me a poor cripple—[[42]]excepting, perhaps, the rare days when I take him woodcock-hunting, when he mildly approves of me.

One night, after waiting a long time at my feet till I should become animate, Rab followed me hopefully into the dark kitchen, where he had never before been allowed to go. I heard his steps behind me only as far as the door, and thought he was afraid to enter; but when I turned on the light, there he stood in the doorway, “frozen” into a beautiful point, his head upturned to a bell and battery on the wall. Presently a mouse hopped from the battery into a waste-basket on the floor, and Rab pointed the thing stanchly, his whole body quivering with delight when a faint odor stole to his nostrils or a rustle of paper to his ears. From the basket the mouse streaked to the coal-hod, and Rab pointed that, too, and then a crack under a door, and a yawning closet drawer. “My bones!” he said, trying to claw the drawer open. “This is a good place; something is alive here!” Then he came over and sat in front of me, looking up in my face, his head twisted sideways, to demand why I had so long kept him out of the only part of the house that was not wholly dormant.

Though the adventure was twelve months ago, “age cannot wither it, nor custom stale its infinite variety,” for every night Rab comes to me [[43]]where I am reading, nudges my elbow, paws my book, sits in front of me to yawn hugely, gives me no peace, in short, till I follow him to the kitchen for another go at the waste-basket, the coal-hod and all the closet drawers. It is of no avail to leave the doors open; he will not go unless I join him in the enjoyment of something that lives. A short time since we flushed another mouse in the cellar, whither he followed me to look after the furnace; and now he pesters me by day as well as by night whenever he finds me, as he thinks, wrapped in unmanly lethargy.

With all his vivacity this young setter, who seems so alert among mere men, becomes a dull creature the moment you compare him with his wild kindred. He cannot begin to interpret the world through his senses as they instantly interpret it, and he would starve to death where they live on the fat of the land. Once on a forest trail I came upon him pointing stanchly at the edge of a little opening that lumbermen had made for yarding logs. Just across the opening, where a jumper road joined the yard, stood a noble buck, and he was “pointing,” too, for he was face to face with such a creature as he had never before seen. Both animals were like statues, so motionless did they stand; but there was this difference, that the dog rested solidly on earth and might have been [[44]]carved from marble, while the buck seemed to rest on air and to be compounded of some ethereal essence. His eyes fairly radiated light and color. The velvet on his antlers seemed to grow as I looked upon it, like the velvet moss in which the fairies are said to rest. Every hair of him from nose to tail tip was gloriously alive. A moment only he stood, but long enough for me to carry a picture of him forever afterward; then he bounded up the old road, and Rab came running over to ask me what new thing he had discovered.

This marvelous alertness of the natural animal is commonly attributed to the fact that his physical senses are more acute than ours; but that is true only of some particular sense of a certain creature. The wolf’s nose, the deer’s ear, the vulture’s eye,—these are probably keener than any similar human organ; but, on the other hand, a man’s eye is very much keener for details than the eye of wolf or deer; his senses of touch and taste are finer than anything to be found among the lower orders, and the average of his five senses is probably the highest upon earth. Yet the animal is more responsive to impressions of the external world, and this is due, I think, to the fact that he lives more in his sensations; that he is not cumbered, as we are, by inner phenomena; that he is free from pain, care, fear, regret, anxiety and [[45]]other mental complexities; that he is accustomed to hear (that is, to receive vibrations) through his feet or his skin quite as much as through his ears; and that his whole body, relaxed and at ease, often becomes a first-class receiving instrument for what we call sense impressions.

As an example of this last, note the wild creature’s response to every change of air pressure, a response so immediate and certain that one might accurately forestall the barometer by observing the action of birds, or even of chickens, which anticipate a storm long before your face has noted the moist wind or your eye the rain-cloud. In the winter woods I have often seen a deer feeding greedily (quite at variance with his usual dainty tasting) at an hour long before or long after his accustomed time, and as I traveled wider I would find other deer doing the same thing. I used to wonder at this, till I noticed that such unusual action was always followed by a storm—not an ordinary brief snowfall, to which deer pay little attention beyond seeking shelter while it lasts, but a severe storm or blizzard, during which most animals lie quiet for a whole day, or even two or three days, without stirring abroad for food.

Whether an element of forethought enters into this act of “stuffing” themselves before a storm, or whether it is wholly instinctive, like the bear’s [[46]]change of diet before he dens for his winter sleep, is a question which does not concern us, since nobody can answer it. In either case the deer have felt, as surely as our most sensitive instruments, not only the decreasing pressure of the air but also its increasing moisture.

That such sensitiveness is not of any one organ, but rather of the whole body, becomes more evident when we study the lower orders—fishes, for example, which may winter under a dozen fathoms of water and a two-foot blanket of ice, but which nevertheless respond to the changing air currents far above their heads. Once on a northern lake, in March, I kept tabs on some trout for fourteen consecutive days, and it seemed that they moved from deep to shallow water or back again whenever the wind veered to the proper quarter. I had a water-hole cut in the thick ice, and, finding a trout under it one day, I kept a couple of lines with minnows there constantly. The hole was in a shallow place, over a sandy bottom, and by putting my face to the opening, with a blanket over my head to exclude the upper light, I could dimly see the shadows move in from deep water. On six scattering days, when the wind came light or strong from the south, two of the days bringing snow, the trout evidently moved shoreward, since I caught them abundantly, as many as I needed [[47]]and some to spare; but on the other eight days, some clear and some stormy, when the wind was north of east or west, not a trout was seen or caught, and only once was a minnow of mine missing.
