Bart, in fact, wove a loose course before his master, running here and there to all points of vantage, as if he knew that danger lurked ahead, but where he came close, with only the narrow passage between the cliffs, he seemed to make up his animal brain that there could be no trouble in so constricted a place, and darted straight ahead.
