"Is it, indeed? I didn't know there was a magnolia there," said Mrs. Sampson, carelessly. Mrs. Manstey looked at her; she did not know that there was a magnolia in the next yard! "By the way," Mrs. Sampson continued, "speaking of Mrs. Black reminds me that the work on the extension is to begin next week." "The what?" it was Mrs. Manstey's turn to ask. "The extension," said Mrs. Sampson, nodding her head in the direction of the ignored magnolia. "You knew, of course, that Mrs. Black was going to build an extension to her house? Yes, ma'am. I hear it is to run right back to the end of the yard. How she can afford to build an extension in these hard times I don't see; but she always was crazy about building. She used to keep a boarding-house in Seventeenth Street, and she nearly ruined herself then by sticking out bow-windows and what not; I should have thought that would have cured her of building, but I guess it's a disease, like drink. Anyhow, the work is to begin on Monday." Mrs. Manstey had grown pale. She always spoke slowly, so the landlady did not heed the long pause which followed. At last Mrs. Manstey said: "Do you know how high the extension will be?" "That's the most absurd part of it. The extension is to be built right up to the roof of the main building; now, did you ever?" "Mrs. Manstey paused again. "Won't it be a great annoyance to you, Mrs. Sampson?" she asked.
