his views he built at least three such "sluice boats." The first was laid down at Dublin in 1662. She distinguished herself by beating all the boats in the harbour, and subsequently outsailed the Holyhead packet, the swiftest vessel that the King had there. Hereupon Petty brought her to England[1] where, probably through the intervention of his friend Pepys, the attention of the Duke of York, then Lord High Admiral, and eventually the notice of the King himself was turned to the novel craft. Charles II. appears to have combined wonder at Petty's energy with quizzical amusement at his numerous projects. He at first chaffed the naviarchal Doctor without mercy[2], but relented sufficiently to attend the launching of a new Double Bottom which he dubbed "The Experiment[3]." She also proved herself a swift sailor, but was presently lost in the Irish Channel. This disaster, followed by the burning of several of his London houses in the great fire and by the adverse decisions of some of his Irish law suits[4], restrained Petty from further shipbuilding experiments for nearly a score of years; but in 1682, while he was considering the establishment at Dublin of a philosophical society similar to that of London, the fit of the Double Bottom, as he tells us, did return very fiercely upon him. His new vessel, however, performed as abominably, as if built on purpose to disappoint in the highest degree every particular that was expected of her and caused him to stagger in much that he had formerly said. But so much did he prefer truth before vanity and imposture that he resolved to spend his life in examining the greatest and noblest of all machines, a ship, and if he found just cause for it to write a book against himself[5].
The Restoration brought Petty no misfortune. A royal letter dated 2 Jan., 1660[6], secured to him all lands that he had held on
