"Ahoy!" shouted a deep voice. "What craft is that?"

"Yacht Puffin, of Aberstour," replied the Patrol-leader.

"Can you take letters ashore for us?" continued the man. "We're three days out from Lowestoft and are bound for Falmouth. No wind and too far to send our boat ashore," he added in support of his request.

"Righto!" shouted Mr. Gregory. "We'll run alongside."

In a few minutes the Puffin was made fast to the stranger's lee quarter, and a small brown paper parcel and about half-a-dozen letters were handed to Mr. Gregory.

"That's all, sir, and thank you," said the skipper of the big yacht. "And if we owe you anything——"

"Not at all," replied Mr. Gregory. "We're Sea Scouts and only too glad to do Good Turns. Let go, please! Touch ahead, Phillips."
