"Bless her!" said the doctor; "of course we can't. She needn't worry about my bill, and you needn't. Between us, Sanderson, we must look out for these three babes in the wood." "Thank you, Doctor." "And, Sanderson," the doctor pursued confidentially, "if you find yourself short of money,--you might, you know,--just let me know. But don't tell anybody, or the Assyrians will be upon me, like the wolf on the fold; and their cohorts won't be gleaming with purple and gold. Not of mine, they won't." Fox laughed. "Thank you again, Doctor. Thank you very much. But I think I shall be able to carry my end, on that basis." Fox did carry his end. He and Henrietta moved to the Ladues' as soon as they could, Fox into the professor's old room, with the skeleton of the professor's little lizard on the floor, under the window, and with the professor's desk to work at. He seemed to have been pushed by chance into the professor's shoes, and he did not like it, altogether. He made a faint-hearted protest at the room. Sally's eyes filled. "Why, Fox," she said, "it's the best room we've got. Isn't it good enough?" "It's much too good, Sally. I don't expect or want such a good room." "Oh, is that all!" Sally was smiling now. "If it's good enough, I guess you'll have to be satisfied. It's ever so much convenienter to give you father's room." So Fox had to be satisfied. Henrietta had the room next Sally's own. That arrangement was "convenienter," too. One of the first things he did at the professor's desk was to write a letter to Miss Martha Havering Hazen. Sally had succeeded in finding her address. "She lives in Whitby, Massachusetts," she announced. "I don't know the name of the street, and I don't know how rich she is." With this, the affairs of Miss Martha Havering Hazen passed from Sally's mind. She had other things to attend to. Fox wrote Miss Hazen a letter in which he set forth, in a very business-like way, the plight in which the Ladue family found themselves, his desire, and Sally's, that Sally's future should be provided for, and the manner in which it was proposed to provide for the aforesaid future. He finished with the statement that the funds at his command were insufficient for all the purposes which it was desired to accomplish, and he inquired whether she were disposed to give any aid and comfort. Then, having posted this, he waited for the answer. He waited for the answer so long that he began to fear that his letter might not have reached Miss Hazen; then he waited until, at last, he was convinced that she never received it, and he had begun to think that she must be a myth. When he reached this conclusion, he was sitting on the piazza and Sally and Henrietta and Doctor Galen were coming up the path together. Sally had her hands behind her. She came and stood before Fox, her eyes twinkling. "Well," she began.
