‘What do you mean by leads?’ asked Vandeloup, considerably puzzled.

Thereupon Archie opened his mouth, and gave the young man a scientific lecture on mining, the pith of which was as follows:—

‘Did ye no ken,’ said Mr McIntosh, sagaciously, ‘in the auld days—I winna say but what it micht be as far back as the Fa’ o’ Man, may be a wee bit farther—the rains washed a’ the gold fra the taps o’ the hills, where the quartz reefs were, down tae the valleys below, where the rivers ye ken were flowin’. And as the ages went on, an’ nature, under the guidance o’ the Almighty, performed her work, the river bed, wiv a’ its gold, would be covered o’er with anither formation, and then the river, or anither yin, would flow on a new bed, and the precious metal would be washed fra the hills in the same way as I tauld ye of, and the second river bed would be also covered o’er, and sae the same game went on and is still progressin’. Sae when the first miners came doon tae this land of Ophir the gold they got by scratchin’ the tap of the earth was the latest deposit, and when ye gae doon a few hundred feet ye come on the second river—or rather, I should say, the bed o’ the former river-and it is there that the gold is tae be found; and these dried-up rivers we ca’ leads. Noo, laddie, ye ma ken that at present we are in the bed o’ ain o’ these auld streams three hun’red feet frae the tap o’ the earth, and it’s here we get the gold, and as we gae on we follow the wandrin’s o’ the river and lose sight o’ it.’

‘Yes,’ said Vandeloup quickly, ‘but you lost this river you call the Devil’s Lead—how was that?’

‘Weel,’ said Mr McIntosh, deliberately, ‘rivers are varra like human bein’s in the queer twists they take, and the Deil’s Lead seems to hae been ain like that. At present we are on the banks o’ it, where we noo get these nuggets; but ‘tis the bed I want, d’ye ken, the centre, for its there the gold is; losh, man,’ he went on, excitedly, rising to his feet and rolling up the plan, ‘ye dinna ken how rich the Deil’s Lead is; there’s just a fortune in it.’

“I suppose these rivers must stop at a certain depth?”

“Ou, ay,” returned the old Scotchman, “we gae doon an’ doon till we come on what we ma ca’ the primary rock, and under that there is nothin’—except,” with a touch of religious enthusiasm, “maybe ‘tis the bottomless pit, where auld Hornie dwells, as we are tauld in the Screepture; noo let us gae up again, an’ I’ll show ye the puddlers at wark.”

Vandeloup had not the least idea what the puddlers were, but desirous of learning, he followed his guide, who led him into another gallery, which formed a kind of loop, and joined again with the main drive. As Gaston stumbled along, he felt a touch on his shoulder, and on turning, saw it was Pierre, who had been put to work with the other men, and was acting as one of the runners.

“Ah! you are there, my friend,” said Vandeloup, coolly, looking at the uncouth figure before him by the feeble glimmer of his candle; “work away, work away; it’s not very pleasant, but at all events,” in a rapid whisper, “it’s better than New Caledonia.”

Pierre nodded in a sullen manner, and went back to his work, while Vandeloup hurried on to catch up to McIntosh, who was now far ahead.
