It was difficult to proceed along the dimly-lighted deck without stumbling over some half-sleeping convict, who retorted by oaths and kicks. Ayrton was, therefore, more than once obliged to halt. But at last he arrived at the partition dividing the after-cabin, and found the door opening into the magazine itself.

Ayrton, compelled to force it open, set to work. It was a difficult operation to perform without noise, for he had to break a padlock. But under his vigorous hand, the padlock broke, and the door was open.

At that moment a hand was laid on Ayrton’s shoulder.

“What are you doing here?” asked a tall man, in a harsh voice, who, standing in the shadow, quickly threw the light of a lantern on Ayrton’s face.

Ayrton drew back. In the rapid flash of the lantern, he had recognised his former accomplice, Bob Harvey, who could not have known him, as he must have thought Ayrton long since dead.

“What are you doing here?” again said Bob Harvey, seizing Ayrton by the waistband.

But Ayrton, without replying, wrenched himself from his grasp and attempted to rush into the magazine. A shot fired into the midst of the powder-casks, and all would be over!

“Help, lads!” shouted Bob Harvey.

At his shout two or three pirates awoke, jumped up, and, rushing on Ayrton, endeavoured to throw him down. He soon extricated himself from their grasp. He fired his revolver, and two of the convicts fell; but a blow from a knife which he could not ward off made a gash in his shoulder.

Ayrton perceived that he could no longer hope to carry out his project. Bob Harvey had reclosed the door of the powder-magazine, and a movement on the deck indicated a general awakening of the pirates. Ayrton must reserve himself to fight at the side of Cyrus Harding. There was nothing for him but flight!
