"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 that he had been observing you and Tredgold so closely; that was all."

"Pity you didn't tell us," exclaimed Tredgold, harshly. "We might have been prepared, then."

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

Mr. Chalk agreed. "I ought to have done so, perhaps," he said, slowly; "only I was afraid of hurting your feelings. As it is, we must make the best of it. It is no good grumbling at each other.

"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."
