"When they got back to the surface, they lay comfortably rocking among the green swells, while they both blew all the used-up air and steam out of their lungs. The feathery little jet of the calf rose gravely beside his mother's high and graceful spout. The calf, always hungry, because he had such a lot of growing to do and was in such a hurry to do it, fell at once to nursing again, while the mother lay basking half asleep. Overhead, some great white gulls flapped and screamed against the sharp blue, now and then dropping with a splash to snatch some fish from the transparent slope of a wave. A couple of hundred yards away three seals lay basking on an ice-floe, and in the distance could be seen other whales spouting. So the mother knew that she and her baby were not alone in these wide bright spaces of sea and sky.
"As a general rule, the great whale was apt to stay not more than two or three minutes at the surface, but to spend most of her time in the moderate depths. Now, however, with her big baby to nurse, she would often linger basking at the surface till her appetite drove her to activity. In general, also, she was apt to be rather careless about keeping watch against her enemies. But now she was vigilant even when she seemed asleep, and anything the least bit out of the ordinary was enough to make her take alarm. As she lay sluggishly rocking, the great blackish round of her head and back now all awash, now rising like a reef above the waves, she suddenly caught sight of a white furry head with a black tip to its nose, swiftly cleaving the water. She knew it was only a white bear swimming, and she knew also that it was not big enough to dare attack her calf. But with her foolish mother fears she objected to its even being in the neighborhood. She swept her dark bulk around so as to hide the little one from the white swimmer's eyes, and lay glaring at him with suspicious fury. The bear, however, hardly condescended to glance at her. He was after those basking seals on the ice-floes. Presently he dived, a long, long dive, and came up suddenly at the very edge of the ice, caught the nearest seal by the throat just as they were all hurling themselves into the water.
"To this unhappy affair the old whale did not give so much as a second look. So long as the bear kept a respectful distance from her precious baby she didn't care how many silly seals he killed.
"But presently she observed, far away among her spouting kindred, the black, slow-moving shape of a steam whaler. In some past experience she had learned that these strange creatures, which seemed to have other creatures, very small, but very, very dangerous, inside of them, were the most to be dreaded of all the whale's enemies. It was at present too far off for her to take alarm, but she lay watching the incomprehensible monster so sharply that she almost forgot to blow. Presently she saw it crawl up quite close to the unsuspecting shape of one of her kinsmen. A spiteful flame leapt from its head. Then a sharp thunder came rapping across the waves, and she saw her giant kinsman hurl himself clear into the air. He fell back with a terrific splash, which set the monster rolling, and, for perhaps a minute, his struggles lashed the sea into foam. Then he lay still, and soon she saw him drawn slowly up till he clung close to the monster's side. This unheard-of action filled her with a terror that was quite sickening. Clutching her calf tremblingly under her fin she plunged once more into the deep, and, traveling as fast as possible for the little one, at a depth of perhaps two hundred feet, she headed for another feeding ground where she trusted that the monster might not follow.
"When she came again to the surface, fifteen minutes later, the monster and all her spouting kinsfolk were out of sight, hidden behind a mile-long mountain of blue ice-berg. But she was not satisfied. Remaining up less than two minutes, to give the calf time for breath, she hurriedly plunged again and continued her journey. When this manoeuver had been repeated half a dozen times she began to feel more at ease. At last she came to a halt, and lay rocking in the seas just off the mouth of a spacious rock-rimmed bay.
"Here, as luck would have it, she found herself in the midst of the food which she loved best. The leaden green of the swells was all flushed and stained with pale pink. This unusual color was caused by hordes of tiny, shrimplike creatures—distant cousins of those which you like so well in a salad. The whale preferred them in the form of soup, so she went sailing slowly through them with her cavernous mouth very wide open. Every now and then she would shut her jaws and give two or three great gulps, and her little eyes, away back at the base of her skull, would almost twinkle with satisfaction.
"But, as it appeared, she was not the only one that liked shrimps. The air was full of wings and screams, where gulls, gannets, and skuas swooped and splashed, quarrelling because they got in one another's way at the feast. Also, here and there a heavy, sucking swirl on the smooth slope of a wave would show where some very big fish was taking toll of the pinky swarms. The whale kept her eye on these ponderous swirls with a certain amount of suspicion, though not really anticipating any danger here.
"She was just about coming to the conclusion that one can have enough, even of shrimps, when, glancing downwards, she caught sight of a long, slender, deadly-looking shape slanting up toward her through a space of clear water between the armies of the shrimps. She knew that grim shape all too well, and it was darting straight at her baby, its terrible sword standing out keen and straight from its pointed snout.
"In spite of her immense bulk and apparently clumsy form, the whale was capable of marvelously quick action. You see, except for her head she was all one bundle of muscle. Swift as thought, she whipped herself clear round, between her calf and the upward rush of the swordfish. She was just in time. The thrust that would have gone clean through the calf, splitting its heart in two, went deep into her own side.
"Withdrawing his terrible weapon, the robber fish whirled about like lightning and made a second dash at the coveted prize. But the mother, holding the little one tight under her flipper, wheeled again in time to intercept the attack, and again received the dreadful thrust in her own flank. So swift was the swordfish (he was a kind of giant mackerel, with all the mackerel's grace and fire and nimbleness) that he seemed to be everywhere at once. The whale was kept spinning around in a dizzy circle of foam, like a whirlpool, with the bewildered calf on the inside. The mighty twisting thrusts of her tail, with its flukes twenty feet wide, set the whole surface boiling for hundreds of yards about.
