"Well," said he, as the partners were taking their leave, "I can't help my opinion, and I've got it still. I believe there's gold on Black Hill Flat, and plenty of it; what's more, it's the sort of nice dry place where it should be pretty near the surface, if it's there at all. But, of course, you might prick about for a year without finding it. I'm sorry I said so much about the place the other day; if I hadn't I'd give you another piece of advice now, and that would be to take your time and go in for deep sinking. You're too good a man for surfacing. Good-afternoon to you, and better luck." And he ducked into his hut with a last least nod. The upshot of this conversation, and of another between Denis and Moseley upon the obvious quality of the deep-sinker, was that Moseley went "pricking about" the flat while Denis persisted in the old hole, and Jim Doherty oscillated between the pair. Nothing more came of it. Moseley was a poor digger, who scarcely pricked skin-deep. He soon went back to his evil cooking, which, however, had been less evil since the little scene with Denis. His chops oftener hit a medium between the blue-raw and done-to-a-rag extremes; but his bread would still have murdered a dyspeptic, and the lean but hungry Doherty was laid up for forty-eight hours after one of Moseley's duffs. Denis himself little knew how many of his sleepless nights he owed to the same devastating cause; and on Black Hill Flat he slept the sleep of the lost. Early to bed was the digger's natural law, but if Denis kept it he would be wide awake by the smallest hours, and so lie tossing till the Flat was astir. He found it a lesser evil to sit up late over a lonely camp-fire, and beguiled these vigils with congenial employment. He was making a new map of the diggings. This one was in ink on a clean piece of cardboard cut to fit the jacket pocket. It grew out of odd scraps marked in pencil on Denis's walks abroad; some of the latter were taken on purpose during these very sleepless nights. So the map was his own, correct or incorrect, and it was made on his own plan. It was largely geological. There were the depths of sinkings where Denis could ascertain them, and the various leads flowed in rivers of bold red ink, which made up for any lack of academic accuracy by a rather stimulating appeal to the imagination. But that was to come; as yet it was a spy's map, which even Jimmy had not seen.
