“Yes, go on then,” said the other eagerly.

“Just as soon as you blaze away, I’ll be ready to jump outside, gun in hand.”

“What for?”

“So as to try to get another crack at some of the other critters. They’ll turn tail, and run a little way off after the crash of the gun inside here and seeing their mate keel over. But it may be light enough for me to see to bowl over one on my own account.”

“I understand now. Do whatever you think best. And just as soon as I’ve pulled the trigger I think I’ll climb out after you.”

“Not a bad idea,” admitted the other; “but now get ready, for I’m going to let out a yell to see what happens.”

Bluff had managed to scramble into a position that gave him a better opportunity to gain his feet in a hurry. He knew there would be considerable need of haste in making his exit, if he hoped to glimpse any of the vanishing wolves after they had been alarmed by the gunshot within the pit.

“Go on!” urged the nervous Jerry, with raised gun, and his eyes fixed on the particular spot where the intruder was again busily at work.

The shout Bluff gave was indeed enough to attract attention. They could hear a movement outside the shelter, as though the invaders had started to retreat, only to come back again, as determined as ever.

Jerry was waiting. All he wanted was just a glimpse of the twin balls of fire not six feet away, when he stood ready to do the duty he had begged Bluff to give into his hands.
