Having failed to detect the source of that strange, intriguing smell, the mink concluded, from past experiences with partridge, grouse, and duck, that it must come from a brooding mother, hiding on a nest in the grass. Nothing could be more satisfactory. His eyes blazed blood-red at the prospect of slaughter. Dropping down again upon all fours, he darted forward, up the trail of the scent, soundless as a shadow and swift as a shifting beam of light,—and came full upon the nest with its three unsheltered eggs. Instantly seizing the nearest one between his agile forepaws, he crunched the shell and began greedily sucking up the contents.
But the savour of the feast had hardly thrilled his palate when it seemed as if the skies had fallen upon him. A scalding anguish stabbed his hunched-up shoulders, a smother of buffeting wings enveloped him, and he was borne backward from the nest in an ignominious bundle, the broken egg-shell still clinging to his nose.
At that moment when he had dropped upon all fours and darted forward through the grass toward the nest, all the immobility of the watching bittern had vanished. His long crest standing straight up in his fury, he had launched himself to the attack, covered the intervening distance with two tremendous thrusts of his powerful wings, and fallen like a cyclone upon the violator of his home. The dagger of his bill had struck deeply, though at random; his hard wing-elbows had landed their blows effectively; and the impetus of his charge had swept the battle clear of the nest, thus saving the two remaining eggs from destruction. The same impetus carried him clear of his foe and a couple of paces past, but he turned adroitly in the air and landed facing about, ready for the inevitable counter-attack.
Amazed and startled though he was, and handled with a roughness quite new to his experience, the mink was in no way daunted. Rather he was so boiling with rage that his wonted wariness forsook him completely. With a snarl that was almost a screech he sprang straight at the long, exposed, inviting throat of his adversary. Had those keen white fangs of his, still dripping with egg, reached their aim, the fight would have been over. His leap was swift, true, and deadly. But equally true, and more swift, was the counter-stroke. He was met, and stopped in mid-air, by a thrust of the bittern's bill, which, had he not twisted his head just in time, would have split his skull. As it was, it laid open one side of his snarling face, destroyed one eye, and brought him heavily to the ground. Even under this punishment, however, he would not acknowledge defeat. Springing aside, with a lightning zigzag movement to confuse the aim of that terrific bill, he darted low and made a leap at his antagonist's long, vulnerable legs. He missed only by a hair's breadth, as the bittern, keenly alive to the risk of such a manoeuvre, leapt nimbly aside and baulked him with a stiff wing-stroke. He seized the baffling wing and strove to pull his tall adversary down. But two great pinion feathers came away in his jaws, and the next moment he got another terrible, driving stab from the dagger beak, well forward on the flank. It was a slanting thrust, or it would have pierced his lungs; but it nearly knocked the wind out of him, and ploughed a deep red gash in his glossy coat.
Screeching furiously, he doubled on himself like a snake to meet this attack. But at the same moment he cringed under another excruciating stab, this time in the haunch; and looking up, he saw himself enveloped in a cloud of blinding wings. The hen bittern had arrived to join in the defence of her nest.
Now, bloodthirsty and merciless marauder though he was, the mink's courage was a thing beyond dispute; and terribly though the fight had so far gone against him, with a single foe to confront he would probably have held on to the death. But for all his fury he was not quite mad; and this reinforcement of the enemy was too much for him. Suddenly straightening himself out long and small like an eel, he slipped from under the terrifying storm of wings and stabs, and made off through the grass at the best speed that in all his swift career he had ever attained. He made for the water, which he felt would be his safest refuge. The angry bitterns were after him on the instant, flying as low as possible and stabbing down at him through the grass-stems. But his cunning and slippery zigzags enabled him to dodge most of their thrusts; and in their eagerness they got in each other's way—which probably saved him his bare life. At length, streaming with blood, and leaving behind him a red trail to proclaim his discomfiture to the mice, he reached the water, and dived in. Without daring to come to the surface he swam across the channel—here about two score paces in width—and cautiously raised his head behind a screen of over-hanging weeds. He saw his two pursuers standing, motionless and erect, on the opposite bank, watching with fierce eyes for him to reappear. He decided not to reappear. Submerging himself again, he swam on down stream till he had rounded a sharp bend of the channel. When he thought it prudent to show himself once more, he was sheltered from those avenging eyes by a dense screen of alder and willows. These bushes were full of nesting red-wings, who chattered at him angrily. He paid no heed to their scolding, but hurried through the thicket, and on down the bank till he found an ancient musk-rat hole. Into this he crept eagerly, and lay down in the grateful dark to nurse his wounds and his humiliation.
After the disappearance of the mink the hen bittern soon returned to her nest. But the male stayed where he was. From time to time he would snap up a butterfly or beetle, or spear a passing frog or chub or sucker. But always his indignant heart was hoping that the mink would return. After an hour or two, however, his wrath died down and he began to forget.
Then he would occasionally vary his still-hunting, by walking with slow, meditative steps up and down the strip of bare ooze between the grass and the water, feeling out with his sensitive claws the little freshwater clams which lay hidden in the mud. The clams were scarce, however, so along about the middle of the afternoon he flapped lazily back to his old fishing station on the other side of the meadow.
Later in the day, when the osiers were beginning to throw long shadows across the water, and the red-and-black butterflies had grown too indolent to dance, and the blue-and-amethyst dragon-flies had ceased their hawking of mosquitoes over the lily-pads and arrow-weed, the great bittern, full fed and at ease with life, flapped languidly up from the water-side and dropped close beside the nest. His brooding mate lifted her head, as if in greeting, and laid it back at once between her shoulders, with her yellow bill pointing skyward as was her vigilant custom.
Soon the first warm tints of sunset began to stain the edges of the clouds above the far fringes of the swamp. Motionless and erect beside his mate, the bittern watched the oncoming of the enchantment as his day drew to its quiet close. Suddenly the coloured quiet of the air was disturbed by the beating of hurried wings. He glanced upward, without moving. A mallard drake, in frantic flight, whirred past, fifteen or twenty feet above his head, making for the water. Close after the fugitive, and swiftly overhauling him with long, tremendous thrusts of his mighty wings, came that most dreaded cut-throat of the air, a great blue goshawk. Swift and bullet-like was the flight of the desperate fugitive; but that of the hawk was far swifter. Had the water been two feet further away the fate of the glossy drake would have been sealed. He would have been overtaken, his throat torn out in mid-air, his body carried off to the nearest tree-top to be plucked and devoured. But this time the inscrutable Fates of the wilderness, too seldom so lenient to the weak, decided to favour him. With a heavy-sounding splash he shot down into the blessed water, and disappeared into safety beneath the lily-pads, just in time.
