"That is enough for the present," Dave said; "we are safe from anyone passing. Now, let us have a look round up above."
"They must have been awful careless if they were surprised in here," Zeke said; "half a dozen men ought to hold this place against a hull tribe of redskins."
"That is so," Boston Joe agreed, "but the greasers are mighty bad watchmen, and no doubt they thought they were safe in here. That Indian village could not have been over on the hill opposite then, or it would have been put down on the map."
"Like enough they had been followed," Dave said. "If a redskin had caught sight of them, he might have followed on their trail for weeks, till he found where they were going, and then made off to bring his tribe down on them. It may be that one has been hanging behind us just in the same way."
"It is a very unpleasant idea," Tom said.
"The redskins' ways aint pleasant," Dave said. "Well, let us be moving up. The first thing we have got to look for aint gold. There is no doubt about that being here somewhere. What we have got to look for is if there is any way out of this hole, because it is a regular trap, and if we were caught here we might hold the gorge for a long time, but they would have us at last certain; besides, they could shoot us down from the top."
They proceeded a few hundred yards up the valley, and then stopped suddenly on a cleared space of ground. In the center lay a score of skeletons, some separately, some in groups of twos and threes. The remnants of the rags that still hung on them showed that they had been Mexicans. The two lads felt a thrill of horror at this proof of the fate that had befallen their predecessors.
"Wall," Zeke exclaimed, "that was something like a surprise; there aint no sign they made a fight of it; they were just caught in their sleep, and never even gathered, for resistance. Well, well, what fools men are to be sure. I shouldn't have believed as even Mexicans would have been such fools as to sleep here without putting a guard at the entrance. I reckon the redskins must have come down from above somewhere, and so caught them unawares. Well, let us be moving on."

A little higher up the valley narrowed again, the sides came closer and closer, until they closed in abruptly in a rounded precipice, down which in the wet season it was evident that a waterfall leaped from a height above.
