“We cut the green lead on the six-hundred-foot, at a hundred and ten feet from the shaft, didn’t we? Well, the men before us cut on the five-hundred at a hundred and seventy from the shaft, and at two-twenty from the shaft on the four-hundred-foot level, where they stoped out a lot of it before concluding it wouldn’t pay to work. It was a strong but almost barren ledge when they first came into it on the two-hundred-foot level. The Bonanza chute made gold because they happened to hit it at a crossing on the four-hundred-foot level. At the six-hundred, as we know, it was almost like a chimney of ore that is playing out as we drift west. If the mill had not been put out of business, we were going to stope it out, though, and prove whether it was the permanent ledge, weren’t we?”
“Right you are, pardner.”
“Well, then, at the same angle, we would have to drift less than seventy feet on the seven-hundred-foot level to cut it again, and at the eight-hundred-foot we’d just about have it at the foot of the shaft. Well, I’m sinking, regardless of expense.”
“It might be right, boy, it might be right,” Bill said, thoughtfully scowling at the plans, and going over the figures of the dip. “But you’re the boss. What you say goes.”
“But don’t you think I’m right?”
“Yes,” hesitatingly, “or, anyway, it’s worth takin’ a chance on. Bells used to say the mines around here all had to get depth, and that most of the ledges came in stronger as they went down. The Cross ain’t shown it so far, but eight hundred feet ought to show whether that’s the right line of work.”
“How is the sump hole under the shaft?” Dick asked.
“Must be somewhere about seventy or eighty feet of water in it; but we can pump that out in no time. She isn’t makin’ much water. Almost a dry mine now, for some reason I don’t quite get. Looks as if it leaked away a good deal, somewhere, through the formation. There wouldn’t be no trouble in sinkin’ the shaft.”
“And thirty feet, about, would bring us to the seven-hundred-foot mark?”
