One evening in the twilight, as I came home from hunting in the big woods, I heard the sound of deer feeding just ahead. I stole forward to the edge of a thicket and stood there motionless, looking and listening intently. My cap was in my pocket, and only my head appeared above the low firs that sheltered me. Suddenly, without noise or warning of any kind, I received a sharp blow on the head from behind, as if some one had struck me with a thorny stick. I turned quickly, surprised and a good bit startled; for I thought myself utterly alone in the woods—and I was. There was nobody there. Not a sound, not a motion broke the twilight stillness. Something trickled on my neck; I put up my hand, to find my hair already wet with blood. More startled than ever, I sprang through the thicket, looking, listening everywhere for sight or sound of my enemy. Still no creature bigger than a wood mouse; no movement save that of nodding fir tips; no sound but the thumping of my own heart, and, far behind me, a sudden rush and a bump or two as the frightened deer broke away; then perfect stillness again, as if nothing had ever lived in the thickets.

I was little more than a boy; and I went home that night more puzzled and more frightened than I have ever been, before or since, in the woods. I ran into the doctor's office on my way. He found three cuts in my scalp, and below them two shorter ones, where pointed things seemed to have been driven through to the bone. He looked at me queerly when I told my story. Of course he did not believe me, and I made no effort to persuade him. Indeed, I scarcely believed myself. But for the blood which stained my handkerchief, and the throbbing pain in my head, I should have doubted the reality of the whole experience.

That night I started up out of sleep, some time towards morning, and said before I was half awake: "It was an owl that hit you on the head—of course it was an owl!" Then I remembered that, years before, an older boy had a horned owl, which he had taken from a nest, and which he kept loose in a dark garret over the shed. None of us younger boys dared go up to the garret, for the owl was always hungry, and the moment a boy's head appeared through the scuttle the owl said Hoooo! and swooped for it. So we used to get acquainted with the big pet by pushing in a dead rat, or a squirrel, or a chicken, on the end of a stick, and climbing in ourselves afterwards.

As I write, the whole picture comes back to me again vividly; the dark, cobwebby old garret, pierced here and there by a pencil of light, in which the motes were dancing; the fierce bird down on the floor in the darkest corner, horns up, eyes gleaming, feathers all a-bristle till he looked big as a bushel basket in the dim light, standing on his game with one foot and tearing it savagely to pieces with the other, snapping his beak and gobbling up feathers, bones and all, in great hungry mouthfuls; and, over the scuttle, two or three small boys staring in eager curiosity, but clinging to each other's coats fearfully, ready to tumble down the ladder with a yell at the first hostile demonstration.

The next afternoon I was back in the big woods to investigate. Fifty feet behind the thicket where I had been struck was a tall dead stub overlooking a little clearing. "That's his watch tower," I thought. "While I was watching the deer, he was up there watching my head, and when it moved he swooped."

I had no intention of giving him another flight at the same game, but hid my fur cap some distance out in the clearing, tied a long string to it, went back into the thicket with the other end of the string, and sat down to wait. A low Whooo-hoo-hoo! came from across the valley to tell me I was not the only watcher in the woods.

Towards dusk I noticed suddenly that the top of the old stub looked a bit peculiar, but it was some time before I made out a big owl sitting up there. I had no idea how long he had been there, nor whence he came. His back was towards me; he sat up very straight and still, so as to make himself just a piece, the tip end, of the stub. As I watched, he hooted once and bent forward to listen. Then I pulled on my string.

With the first rustle of a leaf he whirled and poised forward, in the intense attitude an eagle takes when he sights the prey. On the instant he had sighted the cap, wriggling in and out among the low bushes, and swooped for it like an arrow. Just as he dropped his legs to strike, I gave a sharp pull, and the cap jumped from under him. He missed his strike, but wheeled like a fury and struck again. Another jerk, and again he missed. Then he was at the thicket where I stood; his fierce yellow eyes glared straight into mine for a startled instant, and he brushed me with his wings as he sailed away into the shadow of the spruces.

Small doubt now that I had seen my assailant of the night before; for an owl has regular hunting grounds, and uses the same watch towers night after night. He had seen my head in the thicket, and struck at the first movement. Perceiving his mistake, he kept straight on over my head; so of course there was nothing in sight when I turned. As an owl's flight is perfectly noiseless (the wing feathers are wonderfully soft, and all the laminæ are drawn out into hair points, so that the wings never whirr nor rustle like other birds') I had heard nothing, though he passed close enough to strike, and I was listening intently. And so another mystery of the woods was made plain by a little watching.

Years afterwards, the knowledge gained stood me in good stead in clearing up another mystery. It was in a lumber camp—always a superstitious place—in the heart of a Canada forest. I had followed a wandering herd of caribou too far one day, and late in the afternoon found myself alone at a river, some twenty miles from my camp, on the edge of the barren grounds. Somewhere above me I knew that a crew of lumbermen were at work; so I headed up river to find their camp, if possible, and avoid sleeping out in the snow and bitter cold. It was long after dark, and the moon was flooding forest and river with a wonderful light, when I at last caught sight of the camp. The click of my snowshoes brought a dozen big men to the door. At that moment I felt rather than saw that they seemed troubled and alarmed at seeing me alone; but I was too tired to notice, and no words save those of welcome were spoken until I had eaten heartily. Then, as I started out for another look at the wild beauty of the place under the moonlight, a lumberman followed and touched me on the shoulder.
