Alfred Thornton had been appointed to watch Lieutenant Jimmy Lawton. He was to make him an offer for his patent, if it could be managed without the knowledge of the Government authorities. In any case, he was to wire his father the moment he believed Lieutenant Lawton had completed the model of his boat. It was easy, therefore, to see why Alfred Thornton had cultivated the friendship of Flora Harris. He wished to be about Fortress Monroe in order to hear the gossip of the Army and Navy people, to see Lieutenant Lawton, yet never in any way to be suspected of spying upon him. For this reason Alfred had chosen to live over in the camp with Tom Curtis and his friends, rather than to be any nearer the scene of action. It occurred to the young man on the night of the first rehearsal of their play in Mrs. Curtis's private drawing room that he had been paying too much attention to Madge. He did not wish to estrange Flora Harris. He must be more careful. For this one evening, at least, he would leave Madge to herself. Had Madge been able to read his thoughts she would not have been disturbed at his decision. She was growing tired of her new acquaintance. She thought him dull and too curious about other people's affairs. He was too fond of referring to Phil's friendship for Lieutenant Lawton in a joking manner. For the moment Lieutenant Lawton and the mysterious box occupied her thoughts so completely that she forgot Alfred Thornton's existence. She saw Lieutenant Lawton come into the drawing room, watched him as he explained his unexpected appearance to Mrs. Curtis. Then, looking pale and worried, he took his seat next to Phyllis, though he did not have a chance to say a word to her that would not be overheard. For once Miss Jenny Ann Jones, who had always been the most lenient of chaperons, determined to play the part of a stern dragon. She decided that, of late, the young man had been altogether too attentive to Phyllis. She sat on the girl's side and took part in the conversation between her and the young lieutenant. When he proposed that Miss Alden walk with him in the hotel garden, Miss Jones quietly rose and went out with them. Lieutenant Lawton was desperate. He must give Phyllis the box which he desired her to keep for him before the evening was over. Yet how could he appoint the time and place where she could receive it if he never had a moment with her in private? Miss Jenny Ann entered first the revolving door that formed the ladies' entrance to Mrs. Curtis's hotel. Before the door swung around again Lieutenant Lawton had time to whisper: "You and Miss Morton meet me, if you can, by the tree on the south side of the hotel porch just before you start for the houseboat." Phil had just time to nod in reply when she caught Miss Jenny Ann gazing at her reproachfully through the glass of the door.
