"That's one now!" whispered Tommy.

"That's right!" returned Sandy. "That's one coward!"

"Oh, I see," Tommy whispered. "That's Katz!"

The stranger now approached the fire, swinging his rifle jauntily in his hand and throwing his shoulders back until his body swung forward with a decided strut. He looked from one boy to the other as he came closer, apparently seeking to learn from their expressions exactly what was in their minds. The boys' faces remained perfectly grave.

"It's no use!" Katz said in a moment, putting the butt of his gun down to the ground and leaning on the barrel. "It's no use whatever!"

The boys eyed the speaker suspiciously, but said nothing.

"I followed on as fast as I could!" Katz continued. "But they were on horseback, and I was on foot, so what could I do? Besides, it was too dark that I couldn't see to shoot," he went on.

"Oh, you went out after the robbers, did you?" asked Will, not caring to call the fellow's attention to the fact that he ran away to the north before the riders made their appearance.

"Why, yes!" was the reply. "What else could I do?"

The boys suspected that Katz had returned to the vicinity of the camp in time to hear the officer explain exactly what was going on. They were satisfied that he had not pursued the horsemen at all after they had passed him, but decided not to enter into any argument with him.
