D. Van Nostrand Company, New York Страниц: 456 ISBN: [не указан] This book is designed as a complete text for the practical navigator. No special effort is made to meet any examination requirements. The purpose of the book is rather to present in an orderly manner the latest and best methods of navigation, omitting useless material and reducing space for less essential items. It is hoped and believed that the examiners will be influenced by the methods described, but, in any case, the normal road to progress is for textbooks to advance new and better methods and for practical navigators to put those methods into use.
