Book excerpt: Excerpt from Lectures on Compass Adjustment: Formerly Given to the Navigating Officers of the Royal Navy The following Lectures formed a part of the course of instruction I gave for many years at the Royal Naval College, Greenwich, to audiences composed partly of senior officers, but principally of the Navigating Officers of the Fleet. The lectures were profusely illustrated by diagrams (a selection of which are given in this book), and followed by practical work, originally in a small vessel kept for that purpose in the basin of the Royal Naval Victualling Yard, Deptford, and later on, by means of a large iron model, progress being further tested by Examination Papers principally set by the Superintendent of Compasses, from which a selection is given at the end of each chapter of this book. My classes were, of course, familiar with the use of the compass, and more or less acquainted with the official d104-book on the subject of Adjustment, to which I make frequent reference. The main objects kept in view in this course of instruction were to familiarise executive officers with the mechanical operations involved, and to explain the theory without appealing much to mathematical knowledge. In 1903 the work was transferred to H.M.S. Mercury at Portsmouth, with the great advantage of affording the means of instruction in a sea-going ship. For permission to copy the Charts at the end of this book from the "Manual of Deviations," I am indebted to the courtesy of the Lords Commissioners of the Admiralty.
