He drank again and then sat back among the bushes, still breathing heavily, but with much more freedom. The sharp pain left his chest, new strength began to flow into his muscles, and, as the body was renewed, so the spirit soared up and became sanguine once more. He put his ear to the earth and listened long, but heard nothing, save sounds natural to the wilderness, the rustling of leaves before the light wind, the whisper of the tiny current, and the occasional sweet note of a bird in brilliant dress, pluming itself on a bough in its pride. He drew fresh courage from the peace of the woods, and resolved to remain longer there by the stream. Settling himself into the bushes and tall grass, until he was hidden from all but a trained gaze, he waited, body and soul alike growing steadily in vigor. The forest was in its finest colors. Spring had never brought to it a more splendid robe, gorgeous and glowing, its green adorned with wild flowers, and the bloom of bush and tree like a gigantic stretch of tapestry. The great trunks of oak and elm and maple grew in endless rows and overhead the foliage gleamed, a veil of emerald lace before the sun. Robert drank in the glory, eye and ear, but he never failed to watch the thickets, and to listen for hostile sounds. He knew full well that his life rested upon his vigilance and, often as he had been in danger in the great northern woods, he valued too much these precious days of his youth to risk their sudden end through any neglect of his own. He looked now and then at the bird which still preened itself on a little bough. When the shadows from the waving foliage fell upon its feathers it showed a bright purple, but when the sunlight poured through, it glowed a glossy blue. He did not know its name, but it was a brave bird, a gay bird. Now and then it ceased its hopping back and forth, raised its head and sent forth a deep, sweet, thrilling note, amazing in volume to come from so small a body. Had he dared to make a sound Robert would have whistled a bar or two in reply. The bird was a friend to one alone and in need, and its dauntless melody made his own heart beat higher. If a creature so tiny was not afraid in the wilderness why should he be! He had learned to take sharp notice of everything. On the border and in such times, man was compelled to observe with eye and ear, with all the five senses; and often too with a sixth sense, an intuition, an outgrowth of the other five, developed by long habit and training, which the best of the rangers possessed to a high degree, and in which the lad was not lacking. He knew that the minutest trifle must not escape his attention, or the forfeit might be his life.
