IN due time, Mrs. Darlington removed to a house in Arch Street, the annual rent of which was six hundred dollars, and there began her experiment. The expense of a removal, and the cost of the additional chamber furniture required, exhausted about two hundred dollars of the widow's slender stock of money, and caused her, to feel a little troubled when she noticed the diminution. She began her new business with two boarders, a gentleman and his wife by the name of Grimes, who had entered her house on the recommendation of a friend. They were to pay her the sum of eight dollars a week. A young man named Barling, clerk in a wholesale Market Street house, came next; and he introduced, soon after, a friend of his, a clerk in the same store, named Mason. They were room-mates, and paid three dollars and a half each. Three or four weeks elapsed before any further additions were made; then an advertisement brought several applications. One was from a gentleman who wanted two rooms for himself and wife, a nurse and four children. He wanted the second story front and back chambers, furnished, and was not willing to pay over sixteen dollars, although his oldest child was twelve and his youngest four years of age--seven good eaters and two of the best rooms in the house for sixteen dollars! Mrs. Darlington demurred. The man said-- "Very well, ma'am," in a tone of indifference. "I can find plenty of accommodations quite as good as yours for the price I offer. It's all I pay now." Poor Mrs. Darlington sighed. She had but fifteen dollars yet in the house--that is, boarders who paid this amount weekly--and the rent alone amounted to twelve dollars. Sixteen dollars, she argued with herself, as she sat with her eyes upon the floor, would make a great difference in her income; would, in fact, meet all the expenses of the house. Two good rooms would still remain, and all that she received for these would be so much clear profit. Such was the hurried conclusion of Mrs. Darlington's mind. "I suppose I will have to take you," said she, lifting her eyes to the man's hard features. "But those rooms ought to bring me twenty-four dollars." "Sixteen is the utmost I will pay," replied the man. In fact, I did think of offering only fourteen dollars. "But the rooms are fine, and I like them. Sixteen is a liberal price. Your terms are considerably above the ordinary range." The widow sighed again. If the man heard this sound, it did not touch a single chord of feeling. "Then it is understood that I am to have your rooms at sixteen dollars?" said he. "Yes, sir. I will take you for that." "Very well. My name is Scragg. We will be ready to come in on Monday next. You can have all prepared for us?" "Yes, sir." Scarcely had Mr. Scragg departed, when a gentleman called to know if Mrs. Darlington had a vacant front room in the second story. "I had this morning; but it is taken," replied the widow. "Ah! I'm sorry for that."
