Here a shrinking sensation seemed to come over him again, for he took the cartridge and fingered it about, held the lantern up to the hole he had made, and asked himself whether he had not better go on and drive it through to the water, so as to let it run in, though he knew all the while that a small pump would easily master as much water as forced its way in through such a hole.

Then he tried the fuse.

Yes, there was plenty of that to burn till he reached the foot of the shaft. Perhaps he might be up before the charge exploded. There was nothing to fear, then.

But still he hesitated, and a word or two would have made him give up his task and escape for his life.

It was not to be: for the thought of the money mastered him. He could easily force more from his employer, who dare not refuse; and, to make matters better, he would be having a rich revenge upon Pengelly.

Was it safe to trust his mate about the drawing up?

Bah! What matter! He could escape without his help if he failed; and, rousing his courage to the sticking-point, he vowed he would wait no longer.

The rest was done in desperate haste and with his hands trembling. The tamping was bold, manly work, but he had to deal now with a great cartridge of gunpowder, he told himself, and he must be careful.

He was careful as he thought, but he would have exercised more care if he had known that the stolen cartridge was not gunpowder, but formed of one of the newly-discovered explosives, made by Geoffrey’s own hands.

He laid his fuse ready for attachment, and placed the lantern a little farther back.
