"Don't you yah me, you lubbers," shouted the skipper. "Just you stand by, and don't get up to any tricks. If you du, down the lot o' you goes to Davy in double-quick time."

Having secured uninterrupted possession of the prize, the two skippers returned to their respective boats. Then it was that the crew of the collapsible boat that had been stove in, finding that the fishermen did not kill the prisoners in cold blood, swam to the "Crown and Sceptre" and were taken on board and secured.

"Charlie!" bawled the skipper of the "Unity," "wind's fair for home. Shall us try and take this craft in?"

"No need," replied his friend. "Look astern—there's a Government vessel a-comin' up at the rate o' knots."

CHAPTER XXX

A NOVEL DUCK HUNT

Having secured the surviving Germans from the submarine, and made certain that the Huns had not taken steps to destroy their craft on surrendering, Tressidar "wirelessed" the commander-in-chief at Devonport, reporting the capture and requesting that assistance would be sent to tow the prize into port.

The crews of the two Brixham boats cast off and resumed their interrupted run home, as unconcernedly as if bagging "U" boats was an everyday task. At the same time they took good care formally to make a claim for services rendered to the State, and this Tressidar countersigned according to their request.

It was nearly six in the evening before two destroyers arrived from Devonport. One of them took the captured submarine in tow, the other "stood by" in case another "U" boat might be lurking in the track of the prize.
