"Anything happened while I was asleep?" I enquired.

"All quiet along the Potomac," replied Jim. "Santa Anna had one growling spell, but I guess it was the stomach ache. I skirmished around below the rock but I couldn't find anything."

"You idiot," I said, "didn't you know better than that. It's a wonder that they didn't get you."

"I guess you scared 'em so when you flung the rock at the dark brother that they haven't dared to peep since."

"I suppose that we might as well sit down to our frugal meal," I suggested.

It certainly was as I described it and it made me feel pretty gloomy when I thought how short we were for food and water, especially the latter. Just then we heard a deep growl from Santa, whom Jim had left at the head of the trail on guard.

In a second Jim and I had sprung out on deck to find out the cause of the disturbance. We found Santa barring the way so that Piute and Coyote could not go down the trail.

"Good dog," said Jim, patting him on the head. "The ponies are thirsty, I reckon, and thought that they would go for water. Lucky Santa stopped them."

"We will have to fix it so they can't escape," I said.

This we had no great difficulty in doing. It was the most exciting incident of the day. We found that the Apaches were on the alert, for whenever one of us showed himself, just the lift of the head, there came a quick shot or the unerring flight of an arrow.
