Wherever it has been possible, without clogging the narrative or letting it assume the form of a mere collection of letters, Paul the sailor, like Paul the Apostle, hath been permitted to speak for himself. Contrary to some of his biographers, I have made it a rule to accept Jones' own statements unless they were controverted by adequate evidence. It is proper to call attention to the fact that the intent of the series, of which this is one, which deals primarily with the subjects of the different volumes as great commanders, naturally emphasizes their public exploits rather than their private life. This will account for a lack of amplification in certain directions, and for the omission of details of certain periods of his life which, were the circumstances other than they are, would probably be treated of at greater length. However, it is believed that enough appears in the pages to complete the picture and exhibit the man. There is a great amount of matter available for the study of his life, in the shape of lives, essays, sketches, and general histories, and contemporary memoirs, and an immense mass of manuscript reports and correspondence, and Jones himself left several interesting accounts of his career and services, which are of great value to his biographers. I have freely used all sources of information to which I could gain access, and they have not been few. It will be only justice, however, if I acknowledge that among the authorities consulted I have found the excellent life by Commodore Alexander Slidell Mackenzie, U. S. N., published in 1841, the most useful. Mackenzie was an officer and seaman of wide experience and fine talents, whose life covered the period of our naval development succeeding the War of 1812, and his comments from a sailor's point of view are instructive and invaluable. His work is marred by an unfortunate bias against Jones, which appears in several instances; in a desire to be accurate and just he has gone to a censurable extreme. Two other books have been most helpful: the life by John Henry Sherburne, sometime Register of the United States Navy, published in 1825, with its valuable collection of reports of participants in different actions, and statements and official documents not otherwise preserved; and the life compiled from the manuscript furnished by Miss Janette Taylor, a niece of the great commodore, published in 1830. I may also add that I have found Captain Mahan's admirable papers upon the subject, in Scribner's Magazine, of great value. Indeed, there are facts, observations, and deductions in these articles which appear nowhere else, so sure is the touch of a genius for historical accuracy and investigation like his. Among other essayists, Miss Molly Elliott Seawell, whose facile pen has done so much to exploit our early naval heroes, has written a notable and interesting paper which appeared in the Century Magazine; while Professor John Knox Laughton, the English naval expert, in his
