262 THE ESSEX NATURALIST. Following this Sowerby was asked "to give the necessary instructions to the Officers of Deptford Dock Yard for the erection of six Stacks of Timber." Sowerby was apparently feeling that he should have some considerable payment17 and consulted Knowles who advised him to present an account of the time he had spent on his investigations. He adds "The Vigo a ship built about three years since and heated according to Mr. Lukin's plan is in a bad state from the dry rot; the fungus is seen upon the beams, decks, etc. exteriorly, on the timbers in the inside of the ship. Do you think if we were to fumigate the ship with brimstone that it would stop the vegetation? This is a notion of Mr. Seppings—and he wishes to hear your opinion." Sowerby made his application and in it said "It was gener- ally supposed that the Dryrot had rendered the Queen Charlotte incurable and she is now on service, providentially saved by my directions; I need not mention the value of such saving to those conversant with the subject, it would certainly be enough to afford ample indemnification for my past services ; and, also upon future ones, reckoning upon other first rates etc., assuredly saved and to be saved by such an example properly applied, the amount would be immense." The Navy Board awarded him two hundred guineas "At the same time we deem it necessary to apprize you that in awarding this sum we do not attach to you the merit of having saved the Queen Charlotte by your advice, all the defective materials having been taken out of that ship at Plymouth when she was repaired there." Judging from odd notes, Sowerby had looked forward to "the common rate of salvage" and "something on account of "the example by which so many valuable ships might now be "saved." In January, 1815, he sent in a bill for £45 3s. for regulating and colouring sixteen hygrometers, and for making seven visits to Deptford for advising about the stacking of timber. Dry Rot was now the talk of the town. Pamphlets appeared on the subject and references to the Queen Charlotte figured in all of them. Many and strange specifics were put forward as 17 Lukin received £2,000 for his work on the Queen Charlotte.
