to be Mary’s friend. [19]But the bell did not ring. Instead, Mary presently heard a little click; and then a voice in the hall below called, apparently through the keyhole of the closed door,—“Not at home.” [19] There was a pause, and again,—“Not at home.” A third time the tired, monotonous voice declared untruthfully, “Not at home.” Then there was silence. “John!” cried Mary, horrified. For she thought her brother was playing some naughty trick. What did he mean by such treatment of their first caller? Mary ran down the stairs two steps at a time, and there she found John in the hall, staring with wide eyes at the front door. “What made you—?” began Mary. “I didn’t!” protested John. “It was—Something, I don’t know What, that spoke. When she pushed the bell-button it didn’t ring, but it made that. And now I guess she’s gone off mad!” “Oh, John!” Mary threw open the door and ran to the porch. Sure enough, the visitor was retreating slowly down the path. She turned, however, when she heard Mary open the door, and hesitated, looking rather reproachful. She was very pretty, with red cheeks and bright brown eyes. [20]“Oh! I’m so sorry!” said Mary. “You didn’t ring, did you?” [20] “Yes, I did,” said the girl, looking puzzled. “But I thought no one was at home. Somebody said so.” Her eyes twinkled. Mary liked the twinkle in her eyes. “I don’t understand it!” said Mary, wrinkling her forehead in puzzlement. Then an idea flashed into her head, and she showed her teeth in a broad smile. “Oh, it must have been one of Aunt Nan’s patent jokes.” The girl gave an answering smile. “You mean Miss Corliss?” she suggested. “I know she didn’t like callers. We never ventured to ring the bell in her day. But Mother thought you new neighbors might be different. And I saw you going by yesterday, so I thought I’d try—” She looked at Mary wistfully, with a little cock to her head. “My name is Katy Summers, and we are your nearest neighbors,” she added.
