In a moment there was a scratching noise along the tree trunk, and the weasel came down in long spirals instead of climbing straight down as would a squirrel. The branch at the end of which the chipmunk was perched ran out from the main trunk, then turned at right angles and grew down almost perpendicularly, making a sharp elbow. The weasel descended, weaving his broad, triangular head back and forth, with little looping movements of his long neck, and sniffing the air as he came. When he reached the branch where the chipmunk was, he stopped and crept along the limb to the elbow. This was too much for him, skillful climber as he was. The perpendicular drop of the branch, its small size and smooth bark, all combined against him. Three times he tried to follow it down. Each time he slipped so that it became evident to him that another step would break his hold and send him crashing to the ground.
All this time the chipmunk was in full sight, yet the bloodshot eyes of his enemy seemed to overlook him entirely. Again and again the weasel sniffed the air, and repeatedly returned to the limb, evidently convinced that his intended prey was there.
Throughout, the chipmunk clung to the branch, silent and motionless. Only the throbbing of his silky white breast showed how his heart pounded as he watched the trailing death approaching. At last, the weasel seemed to give up the hunt and reluctantly wound his way down the main trunk and disappeared behind the tree.
For a full half-hour the chipmunk clung to his refuge without the slightest movement. Finally, when it seemed as if his pursuer were gone for good, the little animal moved cautiously up the branch, and managed to negotiate the elbow which had baffled his heavier pursuer. With the same caution he crept down the trunk and, after looking all around, finally leaped to the turf beyond. As he struck the ground, there was a rustle from the depths of a thicket a few rods away, and out darted the weasel, which, with the fierce patience of his kind, had been lurking there and came between the chipmunk and the scattered homes of the colony.
Over the hilltop was the only way of escape. There lay a patch of deep woods, where the trees grew thick and dark over a ledge of rock which stretched up to the very summit. There, too, was hidden some mystery as black as the shade above that lonely ledge. Often there had been no return for chipmunks crossing that dark crest. Instinctively the fugitive avoided the woods and circled the hill hoping to find some refuge on the farther side.
Long ago, the weasel-folk have learned that a straight line is the shortest distance between two points. Wherefore to-day the hunter followed the diameter of the circle that the chipmunk was making around the wooded hilltop. Like a flash, with tail up and head down, the weasel wound his way among the rocks and crowded trees which covered the hill’s crest. As his triangular head thrust itself beyond a pointed rock which jutted out from the ledge, his quick nostrils caught a sinister, sickly scent, and he checked in his stride but—too late. His flaming red eyes looked directly into the fixed glare of two other eyes, black, lidless, with strange oval pupils, and set deep in a cruel heart-shaped head, which showed a curious hole between eye and nostril, the hall-mark of the fatal family of pit-vipers to which the rattlesnake, copperhead, and moccasin belong.
For a second the fierce beast and the grim snake faced each other. The eyes of none of the mammals have a fiercer, more compelling gaze than those of the weasel-folk when red with the rage of slaughter. Yet no beast can outstare that grim ruler of the dark places of the forest, the timber rattlesnake, and in a moment the weasel started to dodge back. Not even his flashing speed, however, availed against the stroke of the snake. Faster than any eye could follow, the flat head shot forward, gaping horribly, while two keen movable fangs were thrust straight out like spear-points. They looked like crooked white needles, each with a hole in the side below the point, from which oozed the yellow venom. Before the darting weasel had time to gain the shelter of the rock, both fangs had pierced his side, and the great snake was back again in coil. Tottering as the deadly virus touched the tide of his fierce blood, and knowing that his life was numbered by seconds, the weasel yet sprang forward to die at death-grips with his foe. As he came, the great snake struck again, but as it snapped back into coil, the needle-like teeth of the other met in its brain. The great reptile thrashed and rattled, but the grip of the red killer remained unbroken long after both were still and stark.
Beyond the black circle of the woods, away from the fatal ledge and through the sunlight, the chipmunk sped, expecting every minute to hear the fierce patter of his pursuer close behind. Little by little he circled, until at last, hardly able to believe in his own escape, he found himself once more in the depths of his own burrow.
As the spring lengthened into summer, Chippy found himself strangely interested in another burrow which had been dug near to his own. So, too, were half a dozen other gay young bucks of the colony, who, with tails erect and with sleek and well-groomed fur, frequently tried to visit the owner of said burrow. She treated them all alike. Every chipmunk who passed her front door received such a succession of nips and scratches that he was only too glad to back out again in a hurry.
