The United States Practical Navigator, in Which All the Calculations Are Made by Arithmetic Classic Reprint

Excerpt from The United States Practical Navigator, in Which All the Calculations Are Made by ArithmeticMany persons who enter the maritime profession do not possess any knowledge of the ordinary rules of computation' others, again, begin their career of following the sea, sufficiently prepared to perform any rule or method of calculation, but who from the nature of a seafaring life, do in the course of a few years, forget their early qualifications, and become altogether incompetent to solve even a question in Plane Sailing.The mariner, therefore, is in want of such practical methods as are most suitable to his calling, and most consistent with his limited acquirements.To supply the seaman's deficiency in this respect, and to facilitate the acquisition of knowledge so important as navigation, have been the Authors' aim and study for years, and it has been found that the best method by which the desired object can be accomplished, is to simplify the rules, so as to enable him without difficulty, to arrive at the greatest possible accuracy in the results.As the clearest and most convincing proof of the correctness and infallibility of these rules, they have worked out in full all of the examples in Bowditch's Navigator, and added Cases and Examples which that author has omitted to give in his Epitome.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
