At a signal from his master, understood perfectly by the sagacious animal, Grumbo, wading and swimming, made his way to the opposite side of the river, where, shaking the water from his shaggy hide, he turned and at a slow dog-trot began following the windings of the shore, keeping his keen and practiced nose bent with sharp and critical attention upon the ground. Abreast, with the water between them, Burl at brisk pace followed the windings of his shore, keeping his keen and practiced eye bent likewise with sharp and critical attention upon the ground, that not a mark or sign unusual in grass, leaves, mud, or sand might pass unnoted by. At intervals along the banks lay wide beds of solid rock, or pebbles mixed with mud or sand, left high and dry by the summer shrinking of the stream, where the Indians might easily have quitted the water without leaving a trace perceptible to the eye. At such places Burl would call Grumbo over to help the eye with the more unerring nose, when, having satisfied themselves that the trail had not yet left the water, the dog, swimming and wading, would return to his side, and abreast the two go on as before. Thus they proceeded till they had searched the banks for nearly a mile and the dog had made his third or fourth passage. Coming then to a bed of limestone rock which spread wide and dry between the edge of the water and the skirts of the forest, Grumbo sent over to his master a short, low bark, which said to the ear addressed, as plainly as words could have said it, "The Red varmints!" Whereat, having satisfied himself that the fording was not more than belly-deep to a tall horse, Burl slipped off his moccasins and leggins, and rolling up his buckskin breeches till nothing was to be seen below his hunting-shirt but his great black legs, now in his turn waded over to the dog's side of the river, sure that here was the place where the Indians had quitted the water and taken again to the woods. In a trice he had reaerranged his toilet, and now was briskly following the unerring Grumbo on the rediscovered trail. But for more than fifty yards after quitting the rocky margin of the stream, not a sign there could he discern, so artfully had the cunning savages concealed or disguised their foot-prints. Cunning as they may have thought themselves, it was all as plain to Grumbo's far-scenting nose as it could have been to Burl's far-sighted eye, and he a reader, had they written it in letters on the ground, "Here we are, and here we go."
