"Oh! I forgot, sir: it puzzles me so. You see, sir, I was sitting here after I got home from your house, thinking what I should do, when Mrs. Flanagan came up stairs with a letter for me, that she said a strange man left at the door for Mrs. Miller; and Mrs. Flanagan couldn't describe him well, or understandingly; and it had no direction at all, only the man inquired who was the landlord, and if Mrs. Miller had a sick child, and then said the letter was for me; and there was no writing inside the letter, but there was fifty dollars. That's all, sir. It gave me a great shock, sir; and I couldn't think who sent it, only when you came to-night, I thought it was you; but you said it wasn't, and I never shall know who it was, now. It seems as if the hand of God was in it, sir, for it came when everything was darkest, and I was in despair." "Why, Mrs. Miller," he slowly answered, "this is very mysterious. The man inquired if I was the owner of the house--oh! no--he only inquired who was--but then he knew I was the--oh! bother! I'm getting nowhere. Let's see. Why, it must be some one you know, or that knows your circumstances." "But there's no one knows them but yourself; and I told you," she replied; "no one else but the people in the house. It must have been some rich person, for the letter was a gilt-edge sheet, and there was perfume in it, sir." "Strange," he murmured. "Well, I give it up. All is, I advise you to keep it, and I'm very glad some one did his duty by you in your hour of need, though I'm sorry it was not myself. Here's Mrs. Flanagan." There was a good deal done, and a great burden lifted off an humble heart--nay, two!--before Dr. Renton thought of going home. There was a patient gained, likely to do Dr. Renton more good than any patient he had lost. There was a kettle singing on the stove, and blowing off a happier steam than any engine ever blew on that railroad whose unmarketable stock had singed Dr. Renton's fingers. There was a yellow gleam flickering from the blazing fire on the sober binding of a good old Book upon a shelf with others, a rarer medical work than ever slipped at auction from Dr. Renton's hands, since it kept the sacred lore of Him who healed the sick, and fed the hungry, and comforted the poor, and who was also the Physician of souls. And there were other offices performed, of lesser range than these, before he rose to go. There were cooling mixtures blended for the sick child; medicines arranged; directions given; and all the items of her tendance orderly foreseen, and put in pigeon-holes of When and How, for service.
