Mr. Richard Revere was a young lieutenant in the navy of the United States. He came of an ancient and honorable family, possessed of wealth and station. He had graduated from the Naval Academy in 1863, and, by an act of daring gallantry in cutting out a blockade-runner, had easily won a lieutenant's commission. When Farragut sailed into Mobile Bay on that hot August morning in 1864, the young man stood on the deck by his side. A Blakely shell from Fort Morgan had seriously wounded him, and this wound, coupled with a long siege of fever subsequently, had almost done for him. Although over a year had elapsed since that eventful day, he had by no means regained his strength, although he seemed now on the fair road to recovery. Anxious to be on duty again after this long period of enforced idleness, he had recently applied for orders, and had been detailed to proceed to Lake Ontario and make arrangements for the sale, or other disposal, of the _Susquehanna_. His mother owned a cottage on one of the Thousand Isles, and the distance was, therefore, inconsiderable. When the orders had reached him there, he determined to sail down to Sewell's Harbor in a little yacht which he had chartered for lake cruising, instead of taking the longer and more tedious journey by land. He had reached his destination in the way which has been told. It was imprudent in him to have attempted to make the mouth of an unknown harbor in such a storm, and he had nearly paid the penalty for his folly with his life. Exhausted by his adventure, he fell speedily into a sound and refreshing slumber, his last thought being of the radiant face bowed over him when he had opened his eyes in the very room in which he now sought rest. He awoke in the morning feeling very much better. On a chair opposite the bed lay a suit of clothes. He glanced at the garments curiously and observed that they were the different articles of a blue-jacket's uniform. They evidently belonged to that sailor-man who had assisted in his rescue. They were new and spotlessly neat; certainly his best suit. His own uniform was nowhere to be seen. It must have been badly torn and, of course, thoroughly soaked by his adventure. His clothes, probably, were not yet fit to put on. If he were to get up at all he must make use of these. Well, it would not be the first time that he had worn a seaman's clothes. They reminded him of his cadet days, and so he arose, somewhat painfully be it known, and dressed himself, curiously surveying the room as he did so. It was a strange room, he thought, for a young girl, as he remembered that it belonged to her. Her? How indefinite that was! He wished he knew her name. He wondered whether it were beautiful enough to be appropriate. He hoped so. The chamber was not at all like that of a young woman. For instance, there was a deadly looking harpoon standing in the corner. He picked up the sinister weapon and examined it.
