Thad felt his companion give a sudden start; he himself was wondering what these strange words of the prospector might mean; though he could not believe that the other could really suspect the presence of that fissure back of the vines.

"As how? Mebbe you wouldn't mind tellin' me, to ease up the pain in my legs; while Waffles, he's astartin' that ere fire?" Dickey Bird went on, skeptically.

"Sure thing," answered the big man who controlled the party of mine seekers. "If that boy does know the secret, he's going to open up while he's got them scouts to back him, ain't he? He'll want to feast his eyes on some of that same rich ore—that goes without saying. All right, let him, say I. We'll try and be close enough at hand to discover whar the pesky entrance lies; and while they're hangin' on up here, it's us to streak it for town and file a claim on that mine by description. First comer gets the persimmon every time. I ain't been in this line of business all my life without learnin' something."

Again did Thad feel his companion move restlessly. It was as though Aleck felt a sudden fear oppress him lest this sly old thief should yet get ahead in entering a claim for the mine.

The flicker of the kindling fire now began to show through the vines at the mouth of the opening. What if these men stayed there until morning, how were the boys to leave? Even when the moon stopped shining upon the face of the cliff, the light of the nearby fire would continue to light it up, so that they would not dare try and creep out. Such a movement, if seen or suspected by the campers, must arouse their curiosity, and lead to an investigation. Then the only thing that could save the mine for Aleck would be a hurried rush to town, in which they might be beaten by the others.

It was not a pleasant thought, although of course, if necessary, the boys could stay there without any great amount of privation. The constant chance of discovery would bother them much more than anything else.

Dickey Bird was still grumbling, it seemed. Things evidently did not please him at all, and only because the fear he entertained for Kracker, the man might have deserted the expedition.

"I jest don't like it around here, and that's what," they heard him say presently. "It ain't the nicest place agoin' either. Now what d'ye reckon that ere rumbling noise was, we all heard a while ago? Waffles, he sez it was thunder; but they ain't nary a cloud as big as my hand anywhar 'round. Sounded more like earthquake noise to me. I was in that shake down at Frisco remember, an' ain't likely to forgit how it starts. If these here mountings began to roll over on us, we'd be in a nice pickle, now, eh? I tell you I don't like it any too much."

"Drop that kind of talk, Dickey Bird," ordered the big prospector, gruffly, "and draw up closer to the fire here. You're cold that's what, and things they looks kind of blue like. Get warmed up and you'll feel better. I've got a little dried meat in my knapsack, and we'll chew on that for a change."

"Good for you, Kunnel!" exclaimed the discontented one, whose mood probably had its inception in hunger, after all. "And don't be long about passin' that same around, will ye? I'm that nigh famished I could eat Indian dog, though I never thought I'd ever come to that."
