Even the gunners on the top were practically useless, for the terrors of the past night and the impending death now awaiting them had shattered their nerves, and they were firing wildly, so that the daring aviators had them at their mercy, for the hornets were about to attack.

Dastral gave one more look round at his flight, and saw them coming boldly on behind him. Then he shouted to Jock:

"All ready there?"

"Aye, ready," came the response.

"Then in mercy's name fire!" A short, sharp nose-dive of two hundred feet, and they were within a hundred feet of the leviathan, and immediately above her. So near were they that they could see the affrighted machine-gunners on the top of the gas-bag leave their posts and try to escape down the escalier, but they had left it too long. They were now about to pay the price for the toll they had wantonly taken of innocent lives during the long dark hours of the past night.
