References in classic literature ?
Yet as he pulled out against the gale he could see that even there had once been a seal nursery.
That nearly broke his heart, and he headed round the Horn back to his own beaches; and on his way north he hauled out on an island full of green trees, where he found an old, old seal who was dying, and Kotick caught fish for him and told him all his sorrows.
And Kotick curled up his mustache (it was a beauty) and said, "I am the only white seal that has ever been born on the beaches, and I am the only seal, black or white, who ever thought of looking for new islands.
Curiously enough, there was another seal who thought that she would put off marrying till the next year, and Kotick danced the Fire-dance with her all down Lukannon Beach the night before he set off on his last exploration.
They were like no walrus, sea lion, seal, bear, whale, shark, fish, squid, or scallop that Kotick had ever seen before.
There were long stretches of smooth-worn rock running for miles, exactly fitted to make seal-nurseries, and there were play-grounds of hard sand sloping inland behind them, and there were rollers for seals to dance in, and long grass to roll in, and sand dunes to climb up and down, and, best of all, Kotick knew by the feel of the water, which never deceives a true sea catch, that no men had ever come there.
He began to think of the seal he had left behind him, but though he was in a hurry to go back to Novastoshnah, he thoroughly explored the new country, so that he would be able to answer all questions.
No one but a sea cow or a seal would have dreamed of there being such a place, and when he looked back at the cliffs even Kotick could hardly believe that he had been under them.
He was six days going home, though he was not swimming slowly; and when he hauled out just above Sea Lion's Neck the first person he met was the seal who had been waiting for him, and she saw by the look in his eyes that he had found his island at last.
But the holluschickie and Sea Catch, his father, and all the other seals laughed at him when he told them what he had discovered, and a young seal about his own age said, "This is all very well, Kotick, but you can't come from no one knows where and order us off like this.
Seal was nonplussed, and stared at her with a puzzled expression, as if she could not classify her among the varieties of human beings known to her.
Seal repeated, half to herself, with a shake of her head, as if that explained what was otherwise inexplicable.
Seal looked up with renewed hope in her eyes, and exclaiming:
Seal began to exhibit signs of discomposure, which displayed themselves by a tossing movement of her head, and, as Ralph took a letter from his pocket, and placed his finger upon a certain sentence, she forestalled him by exclaiming in confusion:
Seal rose at the same time, but remained hovering over the table, delivering herself of a tirade against party government.
