But as he vanished among the hemlocks, trailing his old gun, I knew that he understood the threat. To make the matter sure I drove the deer out of the pond that night, giving them the first of a series of rude lessons in caution, until the falling leaves should make them wild enough to take care of themselves. STILL HUNTING October, the superb month for one who loves the forest, found me again in the same woods, this time not to watch and, learn, but to follow the big buck to his death. Old Wally was ahead of me; but the falling leaves had done their work well. The deer had left the pond at his approach. Here and there on the ridges I found their tracks, and saw them at a distance, shy, wild, alert, ready to take care of themselves in any emergency. The big buck led them everywhere. Already his spirit, grown keen in long battle against his enemies, dominated them all. Even the fawns had learned fear, and followed it as their salvation. Then began the most fascinating experience that comes to one who haunts the woods--the first, thrilling, glorious days of the still-hunter's schooling, with the frost-colored October woods for a schoolroom, and Nature herself for the all-wise teacher. Daylight found me far afield, while the heavy mists hung low and the night smells still clung to the first fallen leaves, moving swift and silent through the chill fragrant mistiness of the lowlands, eye and ear alert for every sign, and face set to the heights where the deer were waiting. Noon found me miles away on the hills, munching my crust thankfully in a sunny opening of the woods, with a brook's music tinkling among the mossy stones at my feet, and the gorgeous crimson and green and gold of the hillside stretching down and away, like a vast Oriental rug of a giant's weaving, to the flash and blue gleam of the distant sea. And everywhere--Nature's last subtle touches to her picture--the sense of a filmy veil let down ere the end was reached, a soft haze on the glowing hilltops, a sheen as of silver mist along the stream in the valley, a fleecy light-shot cloud on the sea, to suggest more, and more beautiful, beyond the veil. Evening found me hurrying homeward through the short twilight, along silent wood roads from which the birds had departed, breathing deep of the pure air with its pungent tang of ripened leaves, sniffing the first night smells, listening now for the yap of a fox, now for the distant bay of a dog to guide me in a short cut over the hills to where my room in the old farmhouse was waiting.
