Contrary to their usual custom in a calm, the earnest desire of all on board was that it should continue, for should a breeze spring up they would be forced to sail away, and the pirates might not pursue them. As soon as it got dark, Wilkinson told the boatswain that it would be as well that a song should be started occasionally, but that not more than five or six men were to join in chorus. If, as they came out, they heard a dead silence they might think it unnatural, and it was quite possible that a boat would come on ahead of them to try and make out what they really were. In the intervals between the songs silence reigned, and all on deck listened intently.
