The plan looked more like a map of a city than anything else, with the main drive doing duty as the principal street, and all the little galleries, branching off in endless confusion, looked like the lanes and alleys of a populous town.

‘It’s like the catacombs in Rome,’ said Vandeloup to McIntosh, after he had contemplated the plan for some time; ’one could easily get lost here.’

‘He micht,’ returned McIntosh, cautiously, ‘if he didna ken a’ aboot the lie of the mine—­o’er yonder,’ putting one finger on the plan and pointing with the other to the right of the tunnel; ’we found a twenty-ounce nugget yesterday, and ain afore that o’ twenty-five, and in the first face we were at twa months ago o’er there,’ pointing to the left, ’there was yin big ain I ca’d the Villiers nugget, which as ye ken is Madame’s name.’

‘Oh, yes, I know that,’ said Vandeloup, much interested; ’do you christen all your nuggets?’

‘If they’re big enough,’ replied Archie.

’Then I hope you will find a hundred-ounce lump of gold, and call it the Vandeloup,’ returned the young man, laughing.

There’s mony a true word spoke in jest, laddie,’ said Archie, gravely; ‘when we get to the Deil’s Lead we may find ain o’ that size.’

‘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?’
