And so the spring ran on towards summer, and the sunshine lay broad and strong over the island; only in one spot the shadow still lay, and crept darker and thicker every day.

But little Jacob saw no shadow, only the light that turned the world to green and gold, and made the rocks grow hot to the touch. He was a pretty little fellow, fair-haired and blue-eyed like the Herons; he might be eight years old at this time, and Isla twelve. It was pretty to see the two playing together. Hand in hand they strayed over the Wild Rocks, talking their silent talk, gathering berries or shells. It was all their own, the south end of the island; the people of the village near the farther end never came here. They were superstitious folk, and had their own ideas about the Wild Rocks, and the dumb woman who dwelt there. Some held it was no mortal wife that Giles Heron had brought home with him those years ago; and they whispered that the first Heron had been banished for witchcraft from parts further south, before he came to our main, and that he had come to escape the burning in Massachusetts. Then he had taken another life and his own, and was it likely such a race as that would go down peacefully like other folks? So there was no one to interfere with Isla and Jacob, and they could be happy in their own way. They had a castle in every rock, a watch-tower in every gnarled and stunted tree. They had playmates, too, in the wild sheep that scampered about the rocky hill-pastures, leaving their shaggy fleece on bush and briar as they ran. Many of these sheep belonged to the people in the fishing village, and were caught once a year and sheared, and let loose again; but some were wholly wild, and could never be caught; and their fleece hung heavy and broad, blackened with wind and weather. Now they knew, these sheep, that the Heron children carried no shears, and that they never tried to drive a sheep except in play, and for play they themselves were quite ready. So many a game went on in the deep, little, green valleys among the Wild Rocks, where the buttercups hide like fairy gold, and the ferns curl and uncurl year by year, unbroken and uncrushed. Jacob might ride on the back of the old black ram, the leader of the wild flock, and Isla could pull his horns, and lead him about, and dress him up with flowers, as if he were a cosset lamb, instead of a fierce old fellow who would knock down a tame sheep as soon as look at him, and whom no other human being save these two had ever dared approach.

There were other friends, too. Sometimes, as the children were sitting at their play on the rocks, there would rise, from the ragged crest of an old fir-tree hard by, a great black bird; would hover an instant, uttering a hoarse croak, which yet had a friendly sound, as of greeting; then, beating his broad wings, would sail out over the water. A second followed him, and the two circled and swung together above the playing children, above the waking, laughing sea. Two ancient ravens, living apart from the noisy crows and the song-sparrows. They knew Isla Heron well, in their age-long wisdom, and loved her in their way. She was not of the same mould as the boys who now and then strayed to the south end of the island, half timid, half defiant; who called them crows, and dared one another to throw stones at them. No stone was ever thrown, however. There was a story on the island of a boy who had once stoned the ravens,—these very birds, or their forbears, and had been set upon by them, and driven backward, shrieking, over the verge of Black Head, to be dashed to pieces on the rocks below. The ravens had taken note of this child since her babyhood, and found her ways much like their own. Sometimes they would sit on a rock near by and watch her, with bright eyes cocked aside, as she strung berries or shells, or plaited garlands of seaweed. Once or twice they had brushed her hair, floating past on outspread wing; and she rightly interpreted this as a token of friendship.

“You might tame them,” her father said when she told him. “Ravens are easy tamed; I read a book once about one.”

“They would not like me any more if I did,” said Isla. “I should hate any one who tried to tame me.” And Giles laughed, and thought it would be no easy task.

Other moods and hours took the children down to the shore; this was especially their delight in the morning, when the simple housework was done, and the mother sat at the spinning by the door (for wherever she came from, she brought her wheel with her, and was a thrifty, hard-working housewife), and the father out in his boat.

Their bathing-place was such as no king ever had. Among the rocks by the water’s edge was one of enormous size and strange form. One might think that some mammoth of forgotten ages had been overtaken by the tide as he lay asleep; had slept into death, and so turned to stone. Seen from a distance, he looked all smooth and gray; but, when one came to climb his vast flanks they were rent and seamed and scarred, and by his shoulder there was tough climbing enough. Near by, a huge, formless mass of rock had fallen off into the sea, and between this and the side of the sleeping monster was a pool of clear shining water. Brown tresses of rockweed, long ribbons of kelp, swung gently to and fro; sprays of emerald green floated through the water; the rocks could be seen at the bottom, and they were green and crimson, with here and there fringes of delicate rose-colour. In and out among the rockweed darted brown shrimps and tiny fish; on the rocks the barnacles opened, waved a plume of fairy feathers, and closed again.

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.
