Stepping back to the cross wall adjoining the door, he crouched down with his head close to the floor and his eyes fixed on a point on the carpet in a line between himself and the window.
‘Do you see anything?’ he asked.
Burnley got into the same position, and looked at the carpet.
‘No,’ he answered slowly, ‘I do not.’
‘You’re not far enough this way. Come here. Now look.’
‘Jove!’ Burnley cried, with excitement in his tones. ‘The cask!’
On the carpet, showing up faintly where the light struck it, was a ring-shaped mark about two feet four inches diameter. The pile was slightly depressed below the general surface, as might have been caused by the rim of a heavy cask.
‘I thought so too,’ said Lefarge, ‘but this makes it quite certain.’
He held out his lens, and indicated the part of the floor he had been scrutinising.
Burnley knelt down and, using the lens, began to push open the interstices of the pile. They were full of a curious kind of dust. He picked out some and examined it on his hand.
