Once more his wife turned on him a face that was like a mask of tragedy. "What difference does it make?" she wailed. "Oh, David! Can't you see? Can't you understand? There I sat--in my own house--like a fool--not knowin' what answer to give her, just because I didn't know what that word meant! And every day something like this happens, something that makes me feel that I'm out of place, something that makes me hate myself! Can't you understand?" Yes, David understood as well as a man could be expected to understand a woman. Many times since Fortune had smiled on him, he had been thrown with men of superior education and social position and had known momentarily the feeling of being out of place. And if Sarah's passionate words failed to convey all she felt and suffered, the despair in her eyes and the nervous twitching of her fingers brought comprehension to her husband's mind. "There! There!" he soothed, taking her hands in his. "You mustn't carry on this way, Sarah, or I'll have to send for the doctor again. Just give me time to think; there must be a way out of this trouble. My goodness!" He shook his head in helpless wonderment over the strange situation. "I thought we'd be through with troubles when we got rich, but it looks as if this money's the most trouble we ever had." "It wouldn't be a trouble if we were used to it," explained Sarah. "We were born poor, and we've lived poor all our lives, and we don't know how to get happiness out of money." David sighed. "We can't go back to Millville to live," he said thoughtfully. "At least we can't get back our old place." Sarah's face was already clouded, but at these words a deeper shadow passed over it. She had known, when she left the Millville house, that the owner of the property intended tearing down the cottage and building a tenement house for the mill-workers, and every time she thought of her house in ruins, she had a dull heartache. "I never hankered after riches," mused David, his mind still occupied with the mysterious ways of the Providence that had made him rich. "I never even tried to invent that machine. It just seemed to come to me, without any thinkin' or tryin' on my part; and when I patented the thing, I never supposed it would do any more than make us fairly comfortable in our old age. But here's the money comin' in all the time; it's ours, and it's honest money, and we've got to take it and make the best of it. But," tenderly, "I'm not goin' to let it worry you to death if I can help it. What is it that bothers you most, honey?" Sarah moved her head restlessly on the pillow and sighed heavily. "Oh! everything; but I believe the servants are the worst aggravation of all." "What's the matter with 'em?" asked David; "don't they do their work right?"
