Melville kept his pony at a walk for no other reason than to prevent any betrayal from the sound of his feet. The distance was slight, and soon he came to a halt on the very edge of the stream, while the rider, peering across, failed to catch the faintest outline of the horsemen that were in sight a short time before. Nothing could have justified the risk of attempting to ride to the other bank; for if the Sioux were in the neighborhood they would not only discover the youth, but would have him at such disadvantage that escape would be out of the question. The lad held no such purpose, but, turning his animal to the right, began making his way down stream, toward the Lower Crossing, near his own home. It was easy to do this by keeping close to the water, since the unevenness of the ground did not begin until a few yards or rods from the bank. The darkness was such that Saladin was left to himself, Melville knowing he could give him no help by any attempt at guiding him. The sagacious beast thrust his nose forward, and, like an elephant, crossing the stream, seemed to feel every foot of the way. Despite the extreme care, he had not taken a dozen steps when a rolling stone caused him to stumble, and the rider narrowly missed taking a header over his ears. Saladin quickly recovered himself, but at the moment of doing so the youth was startled by a whistle from the other shore, instantly answered by a similar call from the bank along which he was riding. This proved that not only were the main party waiting, but the three Sioux that had started to pursue the young fugitive had returned. But if the stumble of Saladin had revealed his whereabouts, Melville was still in great peril. Without waiting to assure himself on the point, he urged his pony to a brisk walk, never pausing until fully two hundred yards were placed behind him. Then, when he looked back and listened, he was convinced his fears were groundless, and it was a simple coincidence that the signals which startled him were emitted at the moment of the slight mishap to his horse. So far as he could judge, he had a clear course now, and he allowed Saladin to advance as rapidly as he chose. His chief distress was concerning Dot. The withdrawal of Red Feather was so sudden that some unusual cause must have been at the bottom. The lad could not help thinking the chieftain should have given him a hint of his course before the youth learned it at such a risk to himself. He was not without fear that harm had befallen his beloved sister, but his confidence in Red Feather was perfect, and he knew that he would do his best to take care of her. Convinced that the Sioux at the Upper Crossing were the ones that had fired the buildings to the south-east, and that they belonged to Tall Bear's band, it followed that something must have taken place to drive them from the siege of Melville's home.
