The shore was dark with the deep green of fir trees, whose straight trunks had blisters on them where drops of fragrant balsam lay hidden in the bark. And here and there trees with white slender trunks leaned out over the water, and the bark on these peeled up like pieces of thin and pretty paper. Three wonderful vines trailed through the woodland, and each in its season blossomed into pink and fragrant bells. But what these were, and how they looked, is not a part of this story, for Gavia never wandered among them. Her summer paths lay upon and under the water of the lake, as her winter trails had been upon and under the water of the sea. Ah, if she loved the water so, why did she suddenly begin to stay out of it? If she delighted so in swimming and diving and chasing wild wing-races over the surface, why did she spend the day quietly in one place? Of course you have guessed it! Gavia was on her nest. She had hidden her two babies among the bulrushes for safety, and must stay there herself to keep them warm. They were not yet out of their eggshells, so the only care they needed for many a long day and night was constant warmth enough for growth. They lay near each other, the two big eggs, of a color that some might call brown and some might call green, with dark-brown spots splashed over them. [Illustration: _Two babies, not yet out of their eggshells, hidden among the rushes._] The nest Gavia and her mate had prepared for them was a heap of old wet reeds and other dead water-plants, which they had piled up among the stems of the rushes until it reached six inches or more out of the water. They were really in the centre of a nest island, with water all about them. So, you see, Gavia was within splashing distance of her fishing-pool after all. She and her mate, indeed, were in the habit of making their nests here in the cove; though the two pairs of Neighbor Loons, who built year after year farther up the lake, chose places on the island near the water-line in the spring; and when the water sank lower later on, they were left high and dry where they had to flounder back and forth to and from the nest, as awkward on land as they were graceful in the water. Faithful to her unhatched young as Gavia was, it is not likely that she alone kept them warm for nearly thirty days and nights; for Father Loon remained close at hand, and would he not help her with this task? Gavia, sitting on her nest, did not look like herself of the early winter months when she had played among the ocean waves. For her head and neck were now a beautiful green, and she wore two white striped collars, while the back of her feather coat was neatly checked off with little white squarish spots. Father Loon wore the same style that she did. Summer and winter, they dressed alike.
