“All right, Joe. I'm as glad as you are Letty's safe. Take care of her. Take care of your wife. Do a stroke of good, back-breaking work once in a while. It'll help that tired feeling of yours that's getting to be dangerously chronic. You've no idea, Joe, what a satisfaction it is, now and then, to feel that you've accomplished something. Try it. Good-bye.” He waved his hand at the woman in the door, who responded with a flutter of her dingy apron; which was immediately thereafter applied to her eyes. Within, by the window, a little pale-faced girl hugged a remarkable doll with yellow hair and a red silk frock. “You'd ought to be pretty proud, Letty Tressler,” said the woman, returning to the small convalescent, “to think Doc kissed you when he left. He's been awful good to you, Doc has, and him with that arm in a sling a-bothering him all the time. But I didn't think he'd do that.” “Maybe it's 'cause I'm so clean now,” speculated the child weakly. “When he did it he whispered in my ear that he liked clean faces.” “Letty, you ain't goin' to have any kind o' face but a clean face after this, jest on account o' Doc Burns,” vowed her mother emotionally, and the child, her doll pressed against her face, nodded. Far down the road Burns was bidding Johnny Caruthers put on more speed. “We have to make time to-day, Johnny,” he explained. “I'm going to get off on that ten-thirty to-night if I have to break my other arm to do it. I don't know that I'd be much more helpless than I am now if I did. Curious, Johnny, how many things there are a man can't do with one hand.” “I should say you could do more with that left hand of yours than most folks can with both,” declared young Caruthers, honest admiration in his eye. Burns laughed--a hearty, care-free laugh. He was in wild spirits, Johnny could see that, and wondered why the Doctor should be so happy over pulling a dead-beat family out of their troubles. Everybody knew Joe Tressler. And Johnny understood that the Doctor had given up going away on Joe's account ten days ago, when he took the case on the eve of his departure. Johnny had seen his employer in all stages of tension since that day, as he had driven him out, at first half-a-dozen times in the twenty-four hours, to this same little old wreck of a house. Johnny had driven him to other houses, also to one especially, in the city, where the lad had sat and speculated much on the extremes of experience in the life of a busy practitioner. It was to this same house that Johnny took Burns next; a house reached by a long drive through wonderful grounds, to a palace of a home within which the man with his arm in the sling disappeared with precisely the same rather brusque and hurried bearing characteristic of him everywhere. But Johnny could not see within. If he had, his honest eyes might have opened still wider. On his way upstairs Burns was intercepted by the master of the house.
