Notes Andrew Gray's 'The experienced millwright' presents the most accurate first-hand account of the state of traditional British millwrighting in the second half of the 18th century. The first three chapters consist of a general treatise on mechanics. The following chapters cover practical directions for the construction of machinery, the mathematics necessary for calculating the strength of machines, and detailed plans for the construction of various kinds of water mills. The text is supplemented by a series of forty-four fine engravings showing the layouts of various types of water-, wind- and animal-powered machinery. The designs and descriptions are mostly of mills and machines which Gray either designed or supervised in actual construction in central-eastern Scotland. As stated in the preface: "the machines of which he has been careful to give accurate drawings and concise explanations are to be considered, not as plans founded on the speculative principles of mechanics ... but as cases of practical knowledge, the effects of which have been fairly tried and long approved". Little is known of Gray, described in his book's preface as "a practical mechanic" who 'has been for at least forty years employed in erecting different kinds of machinery". The text indicates that he is very familiar with the work of the leading civil engineer of the age, John Smeaton (1724-92), and especially Smeaton's seminal paper on the natural powers of water and wind to turn mills and other machines. The second edition of Gray's book corrects 14 textual errors found in the original edition of 1804. The front pastedown of this copy also includes a large printed advertisement for the prospective publication of Gray's 'The plough-wright's assistant' which was eventually published in 1808.
