"Hurrah for a hard afternoon's work," reminded Lillian. "Fall to, my hearties." "Aye, aye, sir," sounded the chorus, and the crew of the "Merry Maid" "fell to." * * * * * "Miss Phyllis Alden, Miss Madge Morton, Miss Lillian Seldon and Miss Eleanor Butler, there is an express package downstairs for you as big as I don't know what!" announced the little maid at Miss Tolliver's Select Seminary for Girls in breathless excitement. "I saw it marked quite plain underneath your name. 'For the Captain and Mates of the "Merry Maid."'" The little maid ran down the steps as quickly as she had traveled up. "It is study hour and we are not supposed to leave our rooms. Do you think we dare go down to the library?" inquired the obedient Eleanor. But the other three girls were already disappearing from the room and were making for the library. Just outside the library door Phil paused. "I'll go and find Miss Tolliver," she said. "Do come and see us open a big box that has just come for us, Miss Tolliver," she begged a moment later, happening to meet the principal in the hall. Nellie had already run off to find Miss Jenny Ann. The express package was long and quite narrow, and Miss Tolliver insisted that a sheet be spread out to protect the library floor. Joseph, the houseman, was sent for to open the box. He hammered and pried out a dozen or more nails. Inside the wooden box was a pasteboard one of exactly the same shape. Phyllis lifted the lid and gave a sharp cry. She and Miss Matilda Tolliver were standing nearest to the box. Miss Tolliver repeated Phil's cry in shriller and more terrified tones. "Be calm, girls, be calm," she commanded the next moment as she dropped into a chair. "Joseph, go for the police. Some one has sent us a bomb to blow up the school." Madge could not help peeping over into the box. Phyllis was shaking with laughter. She had seen a white card sticking out of the funnel of an odd boat-shaped box. The card bore the name of Lieutenant James Mandeville Lawton. "It isn't a bomb, Miss Matilda, it is only a pasteboard model of our friend Lieutenant Jimmy Lawton's torpedo-boat destroyer. Lieutenant Lawton promised to let us hear if he were successful in preventing some people from stealing the patent on his boat. He has just taken this way to let us know he has won. It's awfully jolly!" explained Phil. "I am so glad he remembered us." She picked up the miniature torpedo-boat destroyer and a shower of bonbons fell to the floor. Every one laughed, including Miss Matilda Tolliver. In the top of the box were two flags. One was a little silk flag of the United States Navy. The other one was in blue and white. On it was inscribed: "Long Life to the 'Merry Maid' and Her Merry Maidens."
