"Sauruses it is," Fox returned. "I say, Henrietta, can you climb trees as well as Sally?" "Well, not quite"--hesitating--"but I'm learning." "You live in a cave with Charlie," he said decidedly. CHAPTER XII To tell the truth, the question of money had been troubling Fox somewhat, for he did not have an "awful lot," to use Sally's words. There was enough for him and Henrietta to live upon in great comfort; but when the amount which will support two people in comfort has to take care of five, it needs to be spread pretty thin. To be sure, there was no particular reason why Fox should have felt obliged to look out for the Ladues. One wonders why he did it. That question had occurred to him, naturally, but only to be dismissed at once, unanswered. He could not leave that little family in their misfortunes without visible means of support, and that was the end of it. These considerations will serve to explain Fox's state of mind: why he felt it to be necessary to provide for Sally's future; to see to it that she should have a future of any kind. They may also explain his inquiries about rich relatives. Not that he had, at the moment, any definite idea as to his course of action in the event that she had such desirable and convenient appendages. In fact, it remained to be seen whether they were either desirable or convenient. And he wished very much that it might be considered no impropriety for him and Henrietta to live at the Ladues'. It would simplify many matters. Doctor Galen, to whom he spoke, with some hesitation, of this wish of his, reassured him. "I should say that it would be a very wise move," said the doctor, smiling. "Where is the impropriety?" Fox murmured something about Professor Ladue and about his seeming to take the management of his family out of the professor's hands. He felt a little delicate about making any further move in the same direction. "Pouf!" the doctor exclaimed scornfully. "Ladue has relinquished all right to management, and it's a very fortunate thing that he has. Mrs. Ladue will be very much of an invalid for a number of years, unless all signs fail. There may be some prying people--but there are always. You had better tell Sally that you will come at once. I think it most necessary." Fox was distinctly relieved. He went on to tell the doctor of his conversation with Sally. "And the other children--except Henrietta--have fought shy of coming to see her since that day of the party," he continued. "I suppose they were frightened. They have scarcely been near her. Not that Sally seems to care. I think she is glad when she thinks of them at all. But she has too much care. She takes life too seriously. Why, that party was on her eleventh birthday, and she wants to go out scrubbing or selling papers. Anything to earn money. We can't let her feel so, Doctor; we just can't."
