So Freckles fared through the bitter winter. He was very happy. He had hungered for freedom, love, and appreciation so long! He had been unspeakably lonely at the Home; and the utter loneliness of a great desert or forest is not so difficult to endure as the loneliness of being constantly surrounded by crowds of people who do not care in the least whether one is living or dead. All through the winter Freckles' entire energy was given to keeping up his lines and his “chickens” from freezing or starving. When the first breath of spring touched the Limberlost, and the snow receded before it; when the catkins began to bloom; when there came a hint of green to the trees, bushes, and swale; when the rushes lifted their heads, and the pulse of the newly resurrected season beat strongly in the heart of nature, something new stirred in the breast of the boy. Nature always levies her tribute. Now she laid a powerful hand on the soul of Freckles, to which the boy's whole being responded, though he had not the least idea what was troubling him. Duncan accepted his wife's theory that it was a touch of spring fever, but Freckles knew better. He never had been so well. Clean, hot, and steady the blood pulsed in his veins. He was always hungry, and his most difficult work tired him not at all. For long months, without a single intermission, he had tramped those seven miles of trail twice each day, through every conceivable state of weather. With the heavy club he gave his wires a sure test, and between sections, first in play, afterward to keep his circulation going, he had acquired the skill of an expert drum major. In his work there was exercise for every muscle of his body each hour of the day, at night a bath, wholesome food, and sound sleep in a room that never knew fire. He had gained flesh and color, and developed a greater strength and endurance than anyone ever could have guessed. Nor did the Limberlost contain last year's terrors. He had been with her in her hour of desolation, when stripped bare and deserted, she had stood shivering, as if herself afraid. He had made excursions into the interior until he was familiar with every path and road that ever had been cut. He had sounded the depths of her deepest pools, and had learned why the trees grew so magnificently. He had found that places of swamp and swale were few compared with miles of solid timber-land, concealed by summer's luxuriant undergrowth.
