Here the children came to bathe, swimming about as free and gracefully as the fishes that hardly feared them, or lying at length in the shallows that stretched gold and crystal in the sun, caressed by soft fingers, swept by long, brown tresses; only weeds, were they? who could tell?
Isla loved to lie so, in the summer heat, when the water seemed warm to her hardy limbs, though a landsman might still think it cold. She would tether little Jacob to a rock with a long kelp-ribbon, and he would play contentedly at being a horse, that creature he had never seen save in a picture. There are no horses on the Island of the Wild Rocks.
There the girl would float and dream, her body at rest, her mind out and away with the clouds, or the sea-gulls that hovered and wheeled above the blue sparkling water, till there came a low murmur on the outer reef, a white break against the seaward side of the rock, and she knew that the tide was rising. Then, taking the child by the hand, she would leave the water, and climb up to a great boulder, where the barnacles lay dry in the sun. Only the great spring tides came here; and she would lie on the warm rock, one hand supporting her chin, the other holding Jacob’s hand, and watch the ancient miracle that was always new.
With a swing and a swirl the waters rushed into their pool of peace; the foam sprang high, then fell, and crept up the rock, up, up. Now back, strongly, with a wrench that tugged at the streaming locks, scattering them loose, unrolling the kelp-ribbons to their utmost length. It was gone, and for an instant there was stillness again; then once more came the roar, the inward rush, the snowy column tossed aloft, the white seeking hands creeping up along the rock, till now all the water was a white churn of foam, all the air was filled with driving spray, and the reef thundered with wild artillery. The seas hove bodily over it, and broke only in the cove itself; the place where the children had paused and lingered in their upward climb now boiled like a pot, and even on the top of the great boulder the spray beat in their faces, stinging, burning. A black wing struck athwart the white smoke, and a raven floated past on the wind, one eye cast aside on the children. Isla cried out with glee, and shook her wet hair, and broke into a chant, such as she loved to croon to the wind; but Jacob was timid, and did not like the spray in his face, and, though he heard no sound, shivered at every vibration of the rock as the seas dashed themselves at it; he pulled his sister’s hand, and begged to be gone; so home they went over the mammoth’s back, and left the raven to his own.
