said we were Moral Pirates. That's a very different thing."
"Of course it is," said Joe. "A Moral Pirate is a sort of missionary, you know. I'm afraid you don't go to Sunday-school, officer, or you'd know better."
The policeman could not quite make up his mind whether Joe was in joke or in earnest; but as he could find no real reason for arresting the boys, he contented himself with telling them to leave the lumber-yard as soon as the sun rose. "And you'd better look out," he added, "that you don't come across any real river thieves. They'll make no bones of seizing your boat, and knocking you on the head if you make any noise." When he was fairly out of sight, the boys crept back to their shelter among the lumber, and coolly went to sleep again. They were so tired that neither policemen nor river thieves had any terrors for them.
