Surely it was not to be attained without alcohol. In alcohol lay the secret of this man's trouble. Some little delicacy was needed, however, in showing him that he had read his case aright--that at a glance he had penetrated to the inmost sources of his ailments.

"It's very hot," observed the stranger, mopping his forehead.

"Yes, it is weather which tempts one to drink rather more beer than is good for one," answered Dr. Horace Wilkinson, looking very knowingly at his companion from over his finger-tips.

"Dear, dear, you shouldn't do that."

"I! I never touch beer."

"Neither do I. I've been an abstainer for twenty years."

This was depressing. Dr. Wilkinson blushed until he was nearly as red as the other. "May I ask what I can do for you?" he asked, picking up his stethoscope and tapping it gently against his thumb- nail.

"Yes, I was just going to tell you. I heard of your coming, but I couldn't get round before----" He broke into a nervous little cough.

"Yes?" said the doctor encouragingly.

"I should have been here three weeks ago, but you know how these things get put off." He coughed again behind his large red hand.

"I do not think that you need say anything more," said the doctor, taking over the case with an easy air of command. "Your cough is quite sufficient. It is entirely bronchial by the sound.

Dr. Horace Wilkinson collapsed into his chair. "Then you're not a patient?" he gasped.

"Never needed a doctor in my life, sir."

"Oh, that's all right." The doctor concealed his disappointment under an affectation of facetiousness. "You don't look as if you troubled them much. I don't know what we should do if every one were as robust. I shall call at the company's offices and pay this small amount."

"If you could make it convenient, sir, now that I am here, it would save trouble----"

"Oh, certainly!" These eternal little sordid money troubles were more trying to the doctor than plain living or scanty food. He took out his purse and slid the contents on to the table. There were two half-crowns and some pennies. In his drawer he had ten golden sovereigns. But those were his rent. If he once broke in upon them he was lost. He would starve first.

"Dear me! " said he, with a smile, as at some strange, unheard-of incident. "I have run short of small change.
