Disdaining, however, to pay the least attention to these threats, Shiny William continued to occupy his post with the greatest tranquillity; and the officer, giving up the attempt in despair, proceeded to inquire from us in Portuguese-French the history of this outbreak. The scene concluded with the removal of the mutineers in one of the ship's boats to the man-of-war, where, in a few moments, several dozen lashes were administered to every man in detail, and the whole party were then sent on shore, and committed to a dungeon darker and dirtier than the worst among them had ever before been acquainted with. But before all this was done, and when the boats had pulled about a hundred yards from the vessel, Shiny Bill began to descend from his post. He slipped down unobserved by any one, and the first notice we had of his intentions was from perceiving him run across the deck to the starboard bow, whence he threw himself, without hesitation, into the sea, and began to swim lustily after his captive friends. Our shouts -- for, remembering the abundance of sharks, we were very much alarmed for the poor fellow -- attracted the attention of the officer in the boat, to whom we pointed out the figure of Bill, who seemed as eager now to make a voluntary surrender, and share the fate of his comrades, as he had previously been opposed to a violent seizure. The swimmer was soon picked up, and, to our regret, received in due season the same number of stripes as fell to the lot of his friends captured in battle. The prisoners remained several days in their dungeon, where they were hospitably regaled with bread and water by the Portuguese Government; and at the end of this period (so unworthy did they prove of the handsome treatment they received) the British spirit was humbled within them, and they entreated with tears to be allowed to return to their duty. The mates, however, refused to sail in the same vessel with the carpenter, and it was accordingly settled that he should remain in custody until the arrival of a British man-of-war, and then be returned to his country, passage free. CHAPTER 4. THE PRISON-ISLAND. It was nearly the end of August when we approached the conclusion of our voyage. The wind was fair, the sun shone brightly, and every heart was gay with the hope of once more being upon land. We drew nigh to the Island of Rottnest, about sixteen miles from the mouth of the river Swan, and anchored to the north of it, waiting for a pilot from Fremantle.
