ARTHUR SHOWS HIS COURAGE It must not be supposed that Frank and Archie were entirely unmoved by what had just happened.

The strange conduct of the hounds, and the desperate flight of Johnny's horse, were enough to satisfy them that there was some dangerous animal in the bushes in front of them, and the uncertainty of what that animal might be, caused them no little uneasiness.

Grizzly bears were frequently met with among the mountains, and they sometimes extended their excursions into the plains, occasioning a general stampede among the stock of the nearest ranch.

The grizzly is as much the king of beasts in his own country as the lion in Africa and Asia; and Frank and Archie, during their sojourn at the Old Bear's Hole, had become well enough acquainted with his habits and disposition to know that, if their enemy in the bushes belonged to that species, they were in a dangerous neighborhood.

The grizzly might, at any moment, assume the offensive, and in that event, if their horses became entangled in the bushes, or were rendered unmanageable by fright, their destruction was certain.
