"THE WORK OF DEMOLITION WAS ACCOMPLISHED"

"Two more on the station and then we've finished," exclaimed the Flight-Sub. "Ready?"

"Ay, ay!" replied Ross.

He turned his head to watch the progress of the other sea-planes. One was still maintaining a terrific altitude, and showed no signs of making a volplane.

The other was nowhere to be seen. Perhaps it was as well that the midshipman had not noticed what had befallen her, for a few seconds previously a shrapnel shell had burst close underneath the chassis. The explosion had communicated itself to the remaining bombs, with the result that utter annihilation had overtaken the plucky British airmen in the moment of their triumph.

Ross's companion had witnessed the catastrophe. More, his trained eye had discerned half a dozen small specks in the western sky. Quickly he brought his binoculars to bear upon them. No mistake now; the specks revealed themselves as German aviatiks intent upon cutting off the retreat of the two remaining British air-craft.

Not until Ross had dropped the remaining bombs did his companion speak.

"We've a bit of a shooting match on," he announced. "Get that rifle ready. It's under the coaming on your right hand. Sight at three hundred yards, and let rip when I give the word."

Ross took up the weapon almost as a matter of course. After the excitement of bomb-dropping and being shelled by shrapnel, the approach of a fleet of Zeppelins would hardly disturb his equanimity.
