Now Harland, though considerably astonished by the invitation, was also flattered.

"But my appointment! I never missed an appointment in my life, you know," wavered Harland unsteadily, while shifting his eyes to the door.

"Never mind that now. I'll leave word at the desk. Psst—garçon!"

The Doctor spoke masterfully; the gentleman obeyed him as readily as the servant. A pencil note, with strict injunctions for delivery solved the inebriate's sodden difficulty. Slack insisted upon adding that he would still meet his friend between ten and eleven o'clock. Randolph smiled indulgently, and they passed out into the cool air arm in arm. Randolph hailed a coupé and got his friend into it with pardonable alacrity.

Harland was unusually communicative that evening with the man from whom he would have hardly deigned to accept a cigarette in his college days. He could not understand the reason for what he considered this sudden social degradation. He accepted it in a dazed way, for he had been drinking steadily all day.

The cab stopped before one of the few stone houses less common in Boston than in New York, whose construction is at once singularly deceptive and honest. It had a frontage of seventeen feet.

"A good sized dog-kennel!" observed Harland Slack, glancing at it superciliously as he got out.

"These are my offices," answered Dr. Randolph urbanely, paying no attention to the half-maudlin discourtesy.

Supposing that one of these houses with a frontage of seventeen feet, has a depth of two hundred feet, and is five stories high? The dog-kennel assumes an area of nearly half an acre. There may be large rooms, almost a spacious salon in one of these insignificant homes. Seemingly unlimited space behind ridiculously narrow stone walls, is one of the many mysteries of city life.

Harland Slack sank upon the sofa, and languidly watched the Doctor turn up the gas.
