Miss Sampson was at home this evening. It was not what one would have pictured to oneself as a scene of home comfort or enjoyment; but Miss Sampson was at home. In her little room of fourteen feet square, up a dismal flight of stairs, sitting, in the light of a single lamp, by her air-tight stove, whereon a cup of tea was keeping warm; that, and the open newspaper on the little table in the corner, being the only things in any way cheery about her. Not even a cat or a canary bird had she for companionship. There was no cozy arrangement for daily feminine employment; no workbasket, or litter of spools and tapes; nothing to indicate what might be her daily way of going on. On the broad ledges of the windows, where any other woman would have had a plant or two, there was no array of geraniums or verbenas--not even a seedling orange tree or a monthly rose. But in one of them lay a plaid shawl and a carpet bag, and in the other that peculiar and nearly obsolete piece of feminine property, a paper bandbox, tied about with tape. Packed up for a journey? Reader, Miss Sampson was _always_ packed up. She was that much-enduring, all-foregoing creature, a professional nurse. There would have been no one to feed a cat, or a canary bird, or to water a rose bush, if she had had one. Her home was no more to her than his station at the corner of the street is to the handcart man or the hackney coachman. It was only the place where she might receive orders; whence she might go forth to the toilsomeness and gloom of one sick room after another, returning between each sally and the next to her cheerless post of waiting--keeping her strength for others, and living no life of her own. There was nothing in Miss Sampson's outer woman that would give you, at first glance, an idea of her real energy and peculiar force of character. She was a tall and slender figure, with no superfluous weight of flesh; and her long, thin arms seemed to have grown long and wiry with lifting, and easing, and winding about the poor wrecks of mortality that had lost their own vigor, and were fain to beg a portion of hers. Her face was thin and rigid, too--molded to no mere graces of expression--but with a strong outline, and a habitual compression about the mouth that told you, when you had once learned somewhat of its meaning, of the firm will that would go straight forward to its object, and do, without parade or delay, whatever there might be to be done. Decision, determination, judgment, and readiness were all in that habitual look of a face on which little else had been called out for years. But you would not so have read it at first sight. You would almost inevitably have called her a "scrawny, sour-looking old maid." A creaking step was heard upon the stair, and then a knock of decision at Miss Sampson's door. "Come in!"
