"She's cast off!" shouted a dozen voices.

Such was the case. The two Zeppelins had parted company, one flying off at a terrific speed, rising rapidly as she did so, while the other, being without means of propulsion, drifted at the mercy of the winds.

It was now dawn. The grey light of morning was already overcoming the strength of the searchlights and it was already possible to discern the outlines of the abandoned Zeppelin by the natural light of day.

Pelting up from the eastward came the air squadron of seaplanes. Half a dozen circled and started off in pursuit of the fugitive airship, which, travelling at high speed, was now but a faint speck against the ruddy sky.

The rest advanced boldly upon the disabled Zeppelin, although ignorant of the fact that she had jettisoned her guns, and, save for a few rifles, was without means of defence.

The seaplanes' automatic guns spat viciously, and as the range decreased almost every shot began to tell. The huge fabric once more began to drop, as the small projectile ripped through the flimsy aluminium envelope.

Presently the seaplanes ceased firing and circled triumphantly over their vanquished foe. They knew that the Zeppelin was doomed, and instincts of humanity forbade them to take undue advantage of the plight of her crew.

"Away, boats!" ordered the "Sunderland's" captain.

Instantly there was a rush to man the boats and to stand by the falls. With an alacrity that was part of his nature, Jack Tar prepared to rescue his enemy, in spite of the fact that that enemy had sallied forth with the deliberate intention of hurling bombs with the utmost indiscrimination upon combatants and non-combatants alike, not excepting helpless women and children.

Before the boats could be lowered a lurid blaze of light rolled out, rivalling the rays of the rising sun. Where the Zeppelin had been only a cloud of flame-tinged smoke remained, while from the mushroomed pall of vapour that marked a funereal pyre of yet another unit of the Kaiser's air-fleet, scorched and twisted girders and other débris streamed seawards.
