Sylvia’s heart gave a wild beat; she knew that strange white bird, and had once stolen softly near where it stood in some bright green swamp grass, away over at the other side of the woods. There was an open place where the sunshine always seemed strangely yellow and hot, where tall, nodding rushes grew, and her grandmother had warned her that she might sink in the soft black mud underneath and never be heard of more. Not far beyond were the salt marshes and beyond those was the sea, the sea which Sylvia wondered and dreamed about, but never had looked upon, though its great voice could often be heard above the noise of the woods on stormy nights.

“I can’t think of anything I should like so much as to find that heron’s nest,” the handsome stranger was saying. “I would give ten dollars to anybody who could show it to me,” he added desperately, “and I mean to spend my whole vacation hunting for it if need be. Perhaps it was only migrating, or had been chased out of its own region by some bird of prey.”

Mrs. Tilley gave amazed attention to all this, but Sylvia still watched the toad, not divining, as she might have done at some calmer time, that the creature wished to get to its hole under the doorstep, and was much hindered by the unusual spectators at that hour of the evening. No amount of thought, that night, could decide how many wished-for treasures the ten dollars, so lightly spoken of, would buy.

The next day the young sportsman hovered about the woods, and Sylvia kept him company, having lost her first fear of the friendly lad, who proved to be most kind and sympathetic. He told her many things about the birds and what they knew and where they lived and what they did with themselves. And he gave her a jack-knife, which she thought as great a treasure as if she were a desert-islander. All day long he did not once make her troubled or afraid except when he brought down some unsuspecting singing creature from its bough. Sylvia would have liked him vastly better without his gun; she could not understand why he killed the very birds he seemed to like so much. But as the day waned, Sylvia still watched the young man with loving admiration. She had never seen anybody so charming and delightful; the woman’s heart, asleep in the child, was vaguely thrilled by a dream of love. Some premonition of that great power stirred and swayed these young foresters who traversed the solemn woodlands with soft-footed silent care. They stopped to listen to a bird’s song; they pressed forward again eagerly, parting the branches,—speaking to each other rarely and in whispers; the young man going first and Sylvia following, fascinated, a few steps behind, with her gray eyes dark with excitement.

She grieved because the longed-for white heron was elusive, but she did not lead the guest, she only followed, and there was no such thing as speaking first. The sound of her own unquestioned voice would have terrified her,—it was hard enough to answer yes or no when there was need of that. At last evening began to fall, and they drove the cow home together, and Sylvia smiled with pleasure when they came to the place where she heard the whistle and was afraid only the night before.

II.

Half a mile from home, at the farther edge of the woods, where the land was highest, a great pine-tree stood, the last of its generation. Whether it was left for a boundary mark, or for what reason, no one could say; the woodchoppers who had felled its mates were dead and gone long ago, and a whole forest of sturdy trees, pines and oaks and maples, had grown again. But the stately head of this old pine towered above them all and made a landmark for sea and shore miles and miles away. Sylvia knew it well. She had always believed that whoever climbed to the top of it could see the ocean; and the little girl had often laid her hand on the great rough trunk and looked up wistfully at those dark boughs that the wind always stirred, no matter how hot and still the air might be below. Now she thought of the tree with a new excitement, for why, if one climbed it at break of day, could not one see all the world, and easily discover whence the white heron flew, and mark the place, and find the hidden nest?

What a spirit of adventure, what wild ambition! What fancied triumph and delight and glory for the later morning when she could make known the secret! It was almost too real and too great for the childish heart to bear.

All night the door of the little house stood open, and the whippoorwills came and sang upon the very step. The young sportsman and his old hostess were sound asleep, but Sylvia’s great design kept her broad awake and watching. She forgot to think of sleep. The short summer night seemed as long as the winter darkness, and at last when the whippoorwills ceased, and she was afraid the morning would after all come too soon, she stole out of the house and followed the pasture path through the woods, hastening toward the open ground beyond, listening with a sense of comfort and companionship to the drowsy twitter of a half-awakened bird, whose perch she had jarred in passing. Alas, if the great wave of human interest which flooded for the first time this dull little life should sweep away the satisfactions of an existence heart to heart with nature and the dumb life of the forest!

There was the huge tree asleep yet in the paling moonlight, and small and hopeful Sylvia began with utmost bravery to mount to the top of it, with tingling, eager blood coursing the channels of her whole frame, with her bare feet and fingers, that pinched and held like bird’s claws to the monstrous ladder reaching up, up, almost to the sky itself. First she must mount the white oak tree that grew alongside, where she was almost lost among the dark branches and the green leaves heavy and wet with dew; a bird fluttered off its nest, and a red squirrel ran to and fro and scolded pettishly at the harmless housebreaker. Sylvia felt her way easily. She had often climbed there, and knew that higher still one of the oak’s upper branches chafed against the pine trunk, just where its lower boughs were set close together. There, when she made the dangerous pass from one tree to the other, the great enterprise would really begin.
