"Do you know, professor," said that learned man's wife, when, after supper, he had settled down in his easy-chair to admire the Noah's ark and the duckses' babies and the rest, all of which had arrived safely by express ahead of him and were waiting to be detailed to their appropriate stockings while the children slept--"do you know, I heard such a story of a little newsboy to-day. It was at the meeting of our district charity committee this evening. Miss Linder, our visitor, came right from the house." And she told the story of Mike and Susie. "And I just got the little dollar bill to keep. Here it is." She took the coupon out of her purse and passed it to her husband. "Eh! what?" said the professor, adjusting his spectacles and reading the number. "If here isn't my little dollar come back to me! Why, where have you been, little one? I left you in Bedford Street this morning, and here you come by way of Essex. Well, I declare!" And he told his wife how he had received it in a letter in the morning. "John," she said, with a sudden impulse,--she didn't know, and neither did he, that it was the charm of the little dollar that was working again,--"John, I guess it is a sin to stop it. Jones's children won't have any Christmas tree, because they can't afford it. He told me so this morning when he fixed the furnace. And the baby is sick. Let us give them the little dollar. He is here in the kitchen now." And they did; and the Joneses, and I don't know how many others, had a Merry Christmas because of the blessed little dollar that carried Christmas cheer and good luck wherever it went. For all I know, it may be going yet. Certainly it is a sin to stop it, and if any one has locked it up without knowing that he locked up the Christmas dollar, let him start it right out again. He can tell it easily enough. If he just looks at the number, that's the one. LITTLE WILL'S MESSAGE "It is that or starve, Captain. I can't get a job. God knows I've tried, but without a recommend, it's no use. I ain't no good at beggin'. And--and--there's the childer." There was a desperate note in the man's voice that made the Captain turn and look sharply at him. A swarthy, strongly built man in a rough coat, and with that in his dark face which told that he had lived longer than his years, stood at the door of the Detective Office. His hand that gripped the door handle shook so that the knob rattled in his grasp, but not with fear. He was no stranger to that place. Black Bill's face had looked out from the Rogues' Gallery longer than most of those now there could remember. The Captain looked him over in silence. "You had better not, Bill," he said. "You know what will come of it. When you go up again it will be the last time. And up you go, sure." The man started to say something, but choked it down and went out without a word. The Captain got up and rang his bell.
