S. A. Copyright, 1916, by R. M, PUGSLEY Usually the separate subjects covered by the term “navigation and nautical astronomy” are too roughly generalized for one to readily understand, the result being a constantly increasing demand for a special work for the use of those wishing to study navigation with the intention of obtaining a U. S. Local Inspectors license. The selection and arrangement of the various methods and explanations in detail of keeping track of a ship by “dead reckoning" or "account,” including Mercator and middle latitude sailings, and use of logarithms are not written from theory alone, but from actual practice, and several years' experience as a nautical instructor, which makes possible the production of this volume for the beginner. The matter in this volume is arranged in the proper order for study and should not be deviated from as the nature of the problems in the last part is such that they cannot be managed by those without that knowledge contained in the first part. For that reason it is suggested that the usual custom of beginning study in spots in the advanced portion of a book should not be followed. Bowditch tables have been used throughout and those are referred to where table numbers are mentioned. R. M. PUGSLEY. PUGSLEY'S INCLUDING OF FINDING CAPT. R. M.
