ar out over the pale, smooth surface of the river a crow flew, flapping heavily. From time to time he uttered an angry and frightened squawk. Over, under, and all around him, now darting at his eyes, now dropping upon him like a little, arrow-pointed thunderbolt, now slapping a derisive wing across his formidable beak, flashed a small, dark bird whose silvery white belly now and then caught the sun.

The crow's accustomed alert self-possession was quite shattered. He had forgotten his own powers of attack. He seemed to fear for his eyes,—and among all the wild kindred there is no fear more horrifying than that. When he ducked, and swerved, and tried to dodge, he did it awkwardly, as if his presence of mind was all gone.

His assailant, less than a third of his weight, was a king-bird, whose nest, in the crotch of an elm on the intervale meadow, the crow had been so ill-advised as to investigate. The crow was comparatively inexperienced, or he would have known enough to keep away from the nests of the king-birds. But there it was, in plain sight; and he loved eggs or tender nestlings. Before he had had time to find out which it was that the nest contained, both the parent birds had fallen upon him with a swift ferocity which speedily took away his appetite for food or fight. Their beaks were sturdy and burning sharp. Their short, powerful wings gave them a flight so swift and darting that, for all his superior strength, he felt himself at their mercy. His one thought was to save his eyes and escape.

Both birds chased him till he was well out over the river. Then the female returned to her nest, leaving her mate to complete the intruder's chastisement. Had the crow been an old and cunning bird, he would have sought the extreme heights of air, where the king-bird is disinclined to follow; but lacking this crow-wisdom, he kept on at the level of the tallest tree-tops, and was forced to take his punishment. He was, in reality, more sore and terrified than actually injured. That darting, threatening beak of his pursuer never actually struck his eyes. But for this, it is probable, he had only the indulgence of the king-bird to thank. When at last the chastiser, tired of his task, turned and flew back up the river toward the nest in the elm-crotch, the ruffled crow took refuge out of sight, in the top of the densest hemlock, where he rolled his eyes and preened his plumage silently for an hour before daring again the vicissitudes of the wilderness world.

The nest to which the triumphant king-bird hurried back was audaciously perched in plain view of every prowler. The crotch of the elm-tree which it occupied was about twelve feet from the ground. The intervale, or water-meadow, by the side of the river, held but a few widely scattered trees,—trees of open growth, such as elm, balsam-poplar, and water-ash. It was free from all underbrush. There was nothing, therefore, to shield the nest from even the most careless eyes; and with an insolence of fearlessness matched only by that of the osprey, it was made the more conspicuous by having great tufts of white wool from a neighbouring sheep-pasture woven into its bulky, irregular frame. So irregular and haphazard, indeed, did it appear, that it might almost have been mistaken for a bunch of rubbish left in the tree from the time of freshet. But if the two king-birds relied on this resemblance as a concealment, they presumed as so clever a bird is not likely to do upon the blindness or stupidity of the wild kindred. The wild kindred are seldom blind, and very seldom stupid, because those members of the fellowship who are possessed of such defects sooner or later go to feed their fellows. Hence it was that most of the folk of the riverside, furred or feathered, knew well enough what the big whitish-gray bunch of rubbish in the elm-crotch was.

There were five eggs at the bottom of the smooth, warm cup, which formed the heart of the nest. They were a little smaller than a robin's egg, and of a soft creamy white, blotched irregularly with dull purplish maroon of varying tone. So jealous of these mottled marvels were the king-birds that not even the most harmless of visitors were allowed to look upon them. If so much as a thrush, or a pewee, or a mild-mannered white throat, presumed to alight on the very remotest branch of that elm, it was brusquely driven away.

One morning early, the male king-bird was sitting very erect, as was his custom, on the naked tip of a long, slender, dead branch some ten feet above the nest The morning chill was yet in the air, so it was a little early for the flies which formed his food to be stirring. But he was hungry, and on the alert for the first of them to appear. Only the tense feathers of his crest, raised to show the flame-orange spot which was his kingly crown, betrayed his eagerness; for he was a self-contained bird. The sun was just beginning to show the red topmost edge of his rim through the jagged line of firs across the river, and the long, level streaks of aerial rose, creeping under the branches, filled all the shadowed places of the wilderness with mysterious light. The eastward sides of the tree-trunks and naked branches glimmered pink; and dew-wet leaves, here and there, shone like pale jewels of pink, amber, and violet. The mirror-like surface of the river was blurred with twisting spirals of mist, silvery and opalescent, through which the dim-seen figure of a duck in straight flight shot like a missile.

As the king-bird sat erect on his branch, watching with bright eyes the miracle of the morning, an over-adventurous dragon-fly arose from a weed-top below him and flew into the rosy light. The bird darted straight and true, zigzagged sharply as the victim tried to dodge, caught the lean prize in his beak, and carried it very gallantly to his mate upon the nest. Then he fluttered back to his post on the branch.

As the sun got up over the hill, and the warmth dried their wings, the intervale began to hum softly with dancing flies and hurrying beetles, and the king-bird was continually on the move, twittering with soft monotony (his sole attempt at song), between each successful sally. At length the female rose from her eggs, stood on the edge of the nest, and gave an impatient call. Her mate flew down to take her place, and the two perched side by side, making a low chirping sound in their throats.

Just at this moment a small black snake, warmed into activity and hunger by the first rays of the sun, glided to the tree and began to climb. Bird's-nesting was the black snake's favourite employment; but it had not stopped to consider that the nest in this particular tree was a king-bird's. It climbed swiftly and noiselessly, and the preoccupied birds did not get glimpse of it till it was within two feet of the nest.

There was no time for consultation in the face of this peril. Like lightning the two darted down upon the enemy, buffeting its head with swift wing-strokes. The first assault all but swept it from the tree, and it shrank back upon itself with flattened head and angry hiss. Then it struck fiercely, again and again, at its bewildering assailants. But swift as were its movements, those of the king-birds were swifter, and its fangs never hit upon so much as one harassing feather. Suddenly, in its fury, it struck out too far, weakening for a moment its hold upon the crevices of the bark; and in that moment, both birds striking it together, its squirming folds were hurled to the ground. Thoroughly cowed, it slipped under cover and made off, only a wavering line among the grasses betraying its path. The king-birds, with excited and defiant twittering, followed for a little its hidden retreat, and then returned elated to the nest.

Among the kindred of the wild as well as among those of roof and hearth, events are apt to go in company. For day after day things will revolve in set fashion. Then chance takes sudden interest in a particular spot or a certain individual, and there, for a time, is established a centre for events. This day of the black snake was an eventful day for the little kings of the intervale. They had hardly more than recovered from their excitement over the snake when a red squirrel, his banner of a tail flaunting superbly behind him, came bounding over the grass to their tree. His intentions may have been strictly honourable. But a red squirrel's intentions are liable to change in the face of opportunity. As he ran up the tree, and paused curiously at the nested crotch, a feathered thunderbolt struck him on the side of the head. It knocked him clean out of the tree; and he turned a complete somersault in the air before he could get his balance and spread his legs so as to alight properly. When he reached the ground he fled in dismay, and was soon heard chattering vindictively among the branches of a far-off poplar.

It was a little before noon when came the great event of this eventful day. The male king-bird was on the edge of the nest, feeding a fat moth to his mate. As he straightened up and glanced around he saw a large marsh-hawk winnowing low across the river. As it reached the shore it swooped into the reed-fringe, but rose again without a capture. For a few minutes it quartered the open grass near the bank, hunting for mice. The two king-birds watched it with anxious, angry eyes. Suddenly it sailed straight toward the tree; and the king-birds shot into the air, ready for battle.

It was not the precious nest, however, nor the owners of the nest, on which the fierce eyes of the marsh-hawk had fallen. When he was within twenty paces of the nest he dropped into the grass. There was a moment of thrashing wings, then he rose again, and beat back toward the river with a young muskrat in his talons.

Considering the size and savagery of the hawk, any small bird but the little king would have been well content with his riddance. Not so the king-birds. With shrill chirpings they sped to the rescue. Their wings cuffed the marauder's head in a fashion that confused him. Their wedge-like beaks menaced his eyes and brought blood through the short feathers on the top of his head. He could make no defence or counter-attack against opponents so small and so agile of wing. At length a sharp jab split the lower lid of one eye,—and this added fear to his embarrassment. He dropped the muskrat, which fell into the river and swam off little the worse for the experience.

Relieved of his burden, the hawk made all speed to escape. At the farther shore the female king-bird desisted from the pursuit, and hurried back to her nest. But the avenging wrath of the male was not so easily pacified. Finding the tormentor still at his head, the hawk remembered the security of the upper air, and began to mount in sharp spirals. The king-bird pursued till, seen from the earth, he seemed no bigger than a bee dancing over the hawk's back. Then he disappeared altogether; and the hawk, but for his nervous, harassed flight, might have seemed to be alone in that clear altitude. At last his wings were seen to steady themselves into the tranquil, majestic soaring of his kind. Presently, far below the soaring wings, appeared a tiny dark shape, zigzagging swiftly downward; and soon the king-bird, hastening across the river, alighted once more on his branch and began to preen himself composedly.
