The Old Maid's House: in Plan by Elizabeth Stuart Phelps.

Corona had five hundred dollars and some pluck for her enterprise. She had also at her command a trifle for furnishing. But that seemed very small capital. Her friends at large discouraged her generously. Even Tom said he didn't know about that, and offered her three hundred more.

This manly offer she declined in a womanly manner.

"It is to be my house, thank you, Tom, dear. I can live in yours at home." ...

Corona's architectural library was small. She found on the top shelf one book on the construction of chicken-roosts, a pamphlet in explanation of the kindergarten system, a cook-book that had belonged to her grandmother, and a treatise on crochet. There her domestic literature came to an end. She accordingly bought a book entitled "North American Homes"; then, having, in addition, begged or borrowed everything within two covers relating to architecture that was to be found in her immediate circle of acquaintance, she plunged into that unfamiliar science with hopeful zeal.

The result of her studies was a mixed one. It was necessary, it seemed, to construct the North American home in so many contradictory methods, or else fail forever of life, liberty, and the pursuit of happiness, that Corona felt herself to be laboring under a chronic aberration of mind.... Then the plans. Well, the plans, it must be confessed, Corona did find it difficult to understand. She always had found it difficult to understand such things; but then she had hoped several weeks of close architectural study would shed light upon the density of the subject. She grew quite morbid about it. She counted the steps when she went up-stairs to bed at night. She estimated the bedroom post when she walked in the cold, gray dawn....

But the most perplexing thing about the plans was how one story ever got upon another. Corona's imagination never fully grappled with this fact, although her intellect accepted it. She took her books down-stairs one night, and Susy came and looked them over.

"Why, these houses are all one-story," said Susy. "Besides, they're nothing but lines, anyway. I shouldn't draw a house so."

Corona laughed with some embarrassment and no effort at enlightenment. She was not used to finding herself and Susy so nearly on the same intellectual level as in this instance. She merely asked: "How should you draw it?"

"Why, so," said Susy, after some severe thought. So she took her little blunt lead pencil, that the baby had chewed, and drew her plan as follows:

SUSY'S PLAN

Corona made no comment upon this plan, except to ask Susy if that were the way to spell L; and then to look in the dictionary, and find that it was not spelled at all. Tom came in, and asked to see what they were doing.

"I'm helping Corona," said Susy, with much complacency. "These architects' things don't look any more like houses than they do like the first proposition in Euclid; and the poor girl is puzzled."
