"And there is another thing, Dave," Zeke put in; "we must have a watch. We had intended that, but we thought we should have only one place to watch; now we have found this track up the hill we have two."

"That is so, Dave, though it is pretty hard on us having two out of five idle. Still, we have got a lesson there," Boston said, pointing to the spot where they had found the skeletons.

"Aye, aye, it has got to be done," Dave said. "Well, lads, will you take the watch to-day, one above and one at the mouth, and we will set to work at the water hole?"

"We will toss up which goes up the hill again, Dick. You spin. Heads; tails it is."

"Then I will choose the mouth here. You go up to the mouth's head."

"Don't you be walking about when you get to the top," Dave said. "Find some place where you can get a clear view all round, and then lie down. Choose a bit of shade, if you can find it. When we knock off work and have had a bit of grub, I will come up and take your place."

It was just getting dusk when Dave came up and relieved Dick.

"Are you going to stay here all night, Dick?"

"Yes, we have agreed I shall keep watch here to-night, Boston to-morrow night, and then I go on again. Zeke will take the watch below regular; he sleeps like a dog, and the least noise in the world will wake him, so he will do very well. Can you make out the Indian village across there from here?"

"Yes, quite plainly."
