Dick remonstrated, but in vain. An insolent answer was all he got for his pains. He determined, however, to keep Charlie close beside him all night, and also made up his mind to keep a sharp look-out on the other horses. At supper he again remonstrated. "No 'fraid," said Pierre, whose pipe was beginning to improve his temper. "The red reptiles no dare to come in open plain when de moon so clear." "Dun know that," said a taciturn trapper, who seldom ventured a remark of any kind; "them varmints 'ud steal the two eyes out o' you' head when they set their hearts on't." "Dat ar' umposs'ble, for dey have no hearts," said a half-breed; "dey have von hole vere de heart vas be." This was received with a shout of laughter, in the midst of which an appalling yell was heard, and, as if by magic, four Indians were seen on the backs of four of the best horses, yelling like fiends, and driving all the other horses furiously before them over the plain! How they got there was a complete mystery, but the men did not wait to consider that point. Catching up their guns they sprang after them with the fury of madmen, and were quickly scattered far and wide. Dick ordered Crusoe to follow and help the men, and turned to spring on the back of Charlie; but at that moment he observed an Indian's head and shoulders rise above the grass, not fifty yards in advance from him, so without hesitation he darted forward, intending to pounce upon him. Well would it have been for Dick Varley had he at that time possessed a little more experience of the wiles and stratagems of the Banattees. The Snake nation is subdivided into several tribes, of which those inhabiting the Rocky Mountains, called the Banattees, are the most perfidious. Indeed, they are confessedly the banditti of the hills, and respect neither friend nor foe, but rob all who come in their way. Dick reached the spot where the Indian had disappeared in less than a minute, but no savage was to be seen. Thinking he had crept ahead, he ran on a few yards farther, and darted about hither and thither, while his eye glanced from side to side. Suddenly a shout in the camp attracted his attention, and looking back he beheld the savage on Charlie's back turning to fly. Next moment he was off and away far beyond the hope of recovery. Dick had left his rifle in the camp, otherwise the savage would have gone but a short way. As it was, Dick returned, and sitting down on a mound of grass, stared straight before him with a feeling akin to despair. Even Crusoe could not have helped him had he been there, for nothing on four legs, or on two, could keep pace with Charlie.
