"I think so."

The two Mexicans had gone to the rear of the cave to investigate. The place was long and narrow, making several sharp turns. It was of solid rock, with an uneven flooring. In one spot some water trickled down the side and formed a pool below.

The horses were standing some distance back from the front entrance. They were all but exhausted and needed a long rest before they would be fit to proceed on another journey. Sag Ruff knew this, and it vexed him exceedingly.

"If you don't come out of that, we'll shoot at you," said Maybe Dixon, at last. "We are bound to get you, so you might as well give up now as later."

"Will you compromise?"

"No."

"Then we won't give up, and if you shoot, so will we," answered Sag Ruff.

He was growing reckless and was fit for any deed of daring. A shot rang out and the bullet whistled over his head. He fired two shots in return, one at Maybe Dixon and one at Mark. Then came more shots from outside, but none of them took effect.

"Fire at them!" cried Sag Ruff to Morgan Fitzsimmons. "It's the only way we can keep them back."

The man from Philadelphia did as ordered, but his aim was poor and nobody was struck. The first bullets had grazed the coats of Maybe Dixon and Mark, but that was all.
