'Sakes!' cried the smith, 'whose is that?'

'I don't know,' Sir George answered grimly, and shot a glance of suspicion at Mr. Dunborough, who was leaning against the fore-wheel.

But that gentleman shrugged his shoulders. 'You need not look at me,' he said. 'It is not my box; I have mine here.'

'Whose is it?'

Mr. Dunborough raised his eyebrows and did not answer.

'Do you know?' Sir George persisted fiercely.

'No, I don't. I know no more about it than you do.'

'Maybe the lady took snuff?' the smith said cautiously.

Many ladies did, but not this one; and Sir George sniffed his contempt. He turned the box over and over in his hand. It was a plain, black box, of smooth enamel, about two inches long.

'I believe I have seen one like it,' said Mr. Dunborough, yawning. 'But I'm hanged if I can tell where.'
