At length, the hole being now about three feet deep, Joe, who was working with a crowbar, gave a mighty prod at a loose piece of rock, when, to the astonishment of himself and everybody else, the bottom of the hole fell through, and rock, crowbar and all, disappeared into the cavity beneath.

“Well, what kind of a vein is it, anyhow?” cried Tom, going down upon his knees and peering into the darkness. “Blest if there isn’t a sort of cave down here. Knock out some more, boys, and let me get down. This is the queerest thing I’ve struck in a long time.”

We soon had the hole sufficiently enlarged, when, by means of a rope attached to a tree, Tom slid down into it, and lighting a candle, peered about.

Poor old Tom! The change on his face would have been ludicrous had we not felt so sorry for him, when, looking up at us he said in lugubrious tones: “Done again, boys! Come down and see for yourselves.”

We quickly slid down the rope, when, our eyes having become accustomed to the light, Tom pointed out to us the extraordinary accident that had caused him to believe he had struck a three-foot vein of galena.

Though there was no sign of such a thing on the surface, it was evident that the place in which we stood had at one time been a narrow, water-worn gully in the mountain-side. Ages ago there had been a landslide, filling the little gully with enormous boulders. That these rocks came from the vein of the Samson higher up the mountain was also pretty certain, for among them was one pear-shaped boulder of galena ore, standing upright, upon the apex of which rested the immense four-foot slab of stone through which Tom had bored his drill-hole. By a chance that was truly marvelous, the drill, after piercing the great slab, had struck the very point of the galena boulder and had gone through it from end to end, so that when the core came up it was no wonder that even Tom, experienced miner though he was, should have been deceived into the belief that he had discovered a three-foot vein of lead-ore.

As a matter of fact, there was no vein at all—just one single chunk of galena, not worth the trouble of getting it out. Connor’s lead-mine after all had turned out to be only a “pocket edition.”

Tom’s disappointment was naturally extreme, but, as usual, his low spirits were only momentary. We had hardly climbed up out of the hole again when he suddenly burst out laughing.

“Ho, ho, ho!” he went, slapping his leg. “What will Yetmore say? I’m sorry, Phil, that I couldn’t keep my promise to your father, but I’ll own up that as far as Yetmore is concerned I’m rather glad. I don’t like the Honorable Simon, and that’s a fact. What’s he doing down at the cabin all this time, I wonder. Come! Let’s gather up the tools and go down there: there’s nothing more to be done here.”

On arriving at the cabin, Yetmore’s non-appearance was at once explained. Fastened to the table with a fork was a piece of paper, upon which was written in pencil, “Gone to look for the horses.”
