The smell of blood evidently excited the bears to unusual feats of courage, for they entered the mouth of the cavern and stood growling and showing their teeth within a short distance of where George stood.
Only for the great blaze which now leaped almost to the roof of the cavern, the boy would have been attacked at once. He glanced at the rapidly decreasing pile of wood, and wondered what would take place as soon as the fire had died down. He had no weapon with which to defend himself.
For at least a quarter of an hour the bears and the lad gazed at each other through the red light of the fire. The bears were gradually moving forward, and every time the lad laid a stick of wood on the blaze they seemed to understand more fully that his defense was weakening.
George thought he had never seen wood burn away so fast. The blaze seemed to melt it as boiling water melts ice.
Already the blaze was dropping lower, and the pile of wood was almost gone. The bears sniffed at the blood stains where the boy had lain on the floor, and turned fierce eyes on the figure by the fire.
George estimated that his wood might last ten minutes longer. Then there would be a rush, a crunching of bones and all would be over.
A rifle shot sounded from the outside, and one of the bears dropped to the rocky floor, struggled spasmodically for a moment, and then straightened out and lay still. The next instant another shot, equally accurate, came and the second bear was dead in a moment.
The boy waited eagerly for the appearance of the man who had done the shooting. He had no idea who the man might be, and was not quite certain that the fellow had not taken from him one danger only to place him in another. Still, he looked eagerly forward to his appearance.
When the man appeared, a smoking double-barreled rifle in his hand, George saw a tall, ungainly figure with long legs, a long, slim body, very high cheek bones, and rather stern and uncompromising blue eyes.
The newcomer was dressed in the leather jacket usually worn by trappers in that district, leather leggins, moccasins, and fur cap. A belt of red leather, probably colored and tanned by some Indian process, was drawn tightly about his waist. There were gold rings in his ears which swung an inch down on his brown cheeks.
