night of horror, expecting death every minute. Now he exulted in the
blue sky, the line of white breakers crashing on the reef, and the sea
sparkling in the sunshine; and he had not spent twenty-five years with
Mrs. Chalk without acquiring some skill in the noble art of self-defence.

"Ah, Brisket was trying to pump me a week ago," he said, confidentially.
"I see it all now."

The others glared at him luridly.

"He said that he had seen us through the skylight studying a paper,"
continued Mr. Chalk, shaking his head. "I thought at the time you were
rather rash, Tredgold."

Mr. Tredgold choked and, meeting the fault-finding eye of Mr. Stobell,
began to protest.

"The thing Brisket couldn't understand," said Chalk, gaining confidence
as he proceeded, "was Stobell's behaviour. He said that he couldn't
believe that a man who grumbled at the sea so much as he did could be
sailing for pleasure."

Mr. Stobell glowered fiercely. "Why didn't you tell us before?" he
demanded.

"I didn't attach any importance to it," said Mr. Chalk, truthfully.
"I thought that it was just curiosity on Brisket's part. It surprised me

"You ought to have told us at once," said Stobell.

Mr. Chalk agreed. "I ought to have done so, perhaps," he said, slowly;

"If I had had the map instead of Tredgold, perhaps this wouldn't have
happened."

"It was a crazy idea to keep it in your coat-pocket," said Stobell,
scowling at Tredgold. "No doubt Brisket saw you put it back there the
other night, guessed what it was, and laid his plans according."

"If it hadn't been for your grumbling it wouldn't have happened,"
retorted Tredgold, hotly. "That's what roused his suspicions in the
first instance."

Mr. Chalk interposed. "It is no good you two quarrelling about it," he
said, with kindly severity. "The mischief is done. Bear a hand with
these stores, and then help me to fix the tent up again."

The others hesitated, and then without a word Mr. Stobell worked one of
the casks out of the boat and began to roll it up the beach. The tent
still lay where it had fallen, but the case of spades had disappeared.
They raised the tent again and carried in
