PREFACE TO THIRD EDITION. THE preceding editions of this handbook were received so favorably that it was decided to enlarge the third edition by the addition of further "unified details such as made the earlier editions noteworthy. There has also been included much new matter dealing with ventilation and other subjects, while other portions of the book have been revised and brought up-to-date. It is hoped that in its enlarged form "The Naval Constructor" will continue to occupy its present position as a daily book of reference for those engaged in the design, construction and maintenance of ships.
