mother. “I’ve seen those before,” he grinned. “The boys had them at school once.” “Come, come!” frowned Dr. Corliss. “That was really too bad of Aunt Nan. She knew that almost everybody hates snakes, though she didn’t mind them herself. I’ve often seen her[8] put a live one in her pocket and bring it home to look at.” [8] “Ugh!” shuddered Mrs. Corliss. “I hope they don’t linger about anywhere. I see I shall have to clean the whole house thoroughly from top to bottom. And if I find any more of these jokes—!” Mrs. Corliss nodded her head vigorously, implying bad luck to any snakes that might be playing hide-and-seek in house or garden. Secretly John thought all this was great fun, and he dashed ahead of the rest of the family on their tour of the house, hoping to find still other proofs of Aunt Nan’s special kind of humor. But to the relief of Mary and her mother the rest of their first exploring expedition was uneventful. They visited dining-room and kitchen and pantry, and the room that was to be Dr. Corliss’s study. Then they climbed the stairs to the bedroom floor, where there were three pretty little chambers. They took a peep into the attic; but even there, in the crowded shadows and cobwebs, nothing mysterious happened. It was a nice old house where the family felt that they were going to be very happy and contented. Down the stairs they came once more, to the[9] door of the ell which they had not yet visited. It was a brown wooden door with a glass knob. [9] “Well, here is your domain, Mary!” said Dr. Corliss, pausing and pointing to the door with a smile. “This is your library, my daughter. Have you the key ready?” Yes, indeed, Mary had the key ready; a great key tagged carefully,—as all the other keys of Aunt Nan’s property had been,—this one bearing the legend: “LIBRARY. Property of Mary Corliss.” “Here is the key, Father,” said Mary, stepping up proudly. “Let me put it in myself. Oh, I hope there are no horrid jokes in here!” And she hesitated a moment before fitting the key in the lock of her library—her very own library!
