“Aw, that ain’t copper,” he declared, “it’s just this green hornblende. We have it around here everywhere.”

“All right”, answered Denver, “you can have it your own way–but I call it copper, myself.”

“Vot–copper?” demanded the Professor making a clutch at the specimen and examining it with his myopic eyes, and then he broke into a roar. “Vot–dat copper?” he cried, “you think dat is copper? Oh, 106ho, ho! Oh, vell! Dis is pretty rich. It is nutting but manganese!”

“That’s all right,” returned Denver, “you can think whatever you please; but I’ve worked underground in too many copper mines─”

“Where’d you get this?” broke in Bunker, giving Denver a dig, and as they went into the tunnel he whispered in his ear: “Keep it dark, or he’ll blab to Murray!”

“Well, let him blab,” answered Denver, “it’s nothing to me. But all the same, pardner,” he added sotto voce, “if I was in your place I wouldn’t bank too much on holding them claims with a lead-pencil.”

“I’m holding ’em with a six-shooter,” corrected Bunker, “and Murray or nobody else don’t dare to jump a claim. I’m known around these parts.”

“Suit yourself,” shrugged Denver as they came to the face, “I guess this ore won’t start no stampede. That seam in the hanging wall is where it comes in–I’m looking for the veins to come together.”

“Judas priest!” exclaimed Bunker jabbing his candlestick into the copper streak, “say, this is showing up good. And your silver vein is widening out, too. Nothing to it, boy; you’ve got a mine!”

“Not yet,” said Denver, “but wait till she dips. This is nothing but a blanket vein, so far; but if she dips and goes down then look out, old-timer, she’s liable to turn out a bonanza.”
