Maury had an exceeding fondness for the sea, which was fostered by the adventures of his elder brother, who entered the United States navy when but thirteen years of age. When Maury made known his determination to accept the position of midshipman, which the Hon. Sam Houston obtained for him, his father did not command him to decline; but he did not approve it, and would not give him any financial aid, or even his blessing. This was a great grief to Maury, but he had put his hand on the helm, and there was no turning back. So, borrowing a horse, and with only thirty dollars in his pocket, and the limited experience of nineteen years, he set out to seek his fortune. There was no naval academy, and the young middy began his duties and his studies on board a man-of-war. What powers of concentration he possessed, with what unflagging zeal he pursued his studies, proving by his subsequent career that genius is the capacity for labor. William Irving, brother of Washington Irving, loaned him many books. During his first year of service his frigate, the Brandywine, conveyed Lafayette back to France. The great Frenchman was much attracted by the young midshipman, and had many a kind talk with him. In 1831 he passed his examination, was appointed master of the sloop-of-war Falmouth, and ordered to the Pacific on a four years’ cruise. It was on this voyage that Maury conceived the idea of the famous “Winds and Currents Charts,” which have done so much for the commerce of the world. He returned to the United States in 1834 and married his cousin, Miss Herndon, to whom he had been engaged several years. Shortly after this marriage he went to Philadelphia to arrange for the publication of his works on navigation. His book, like himself, had the true ring or true metal, and won distinction In England and became the text-book of the United States navy. At this period Maury obtained leave of absence, and on his way to his old home in Tennessee he was thrown from the top of a stage coach, which resulted in an accident that lamed him for life and interrupted his active service afloat. His leg was improperly set, had to be broken again and reset, and this in a day when anaesthetics were unknown. This period of enforced inactivity was most distressing to the ambitious lieutenant, but proved a blessing in disguise, for it was then that his active mind turned to and grasped the scientific part of his profession. In 1839 he began a series of articles on naval reform. He advised that a navy yard and forts can be established on the Gulf coast. “They cannot be too strongly fortified with outfits for shipping and implements of war.” He advocated also a naval school for young midshipmen. This article led to the building of forts at Key West and the Tortugas, and the establishment of the naval academy at Annapolis.
