"Aye, I know;"—the big, shaggy head nodded slowly, and the words dropped one by one from the full, protruding lips. "The world's a dream while it lasts.... You walk among shadows, without she's there.... There's no sleep at night,—there's only thinking, and tossing, and sweating—and heugh! the next hour strikes!... And one day it's heaven, and the next hell.... And it ends——"

There was a long silence.

"It was twenty years ago," said the doctor, simply. "Tommy lad, would you—would you care to hear about it? You shall." He covered his eyes with his hand and had begun to speak ere he removed it. "I was about your age, but I was still at college; I left late. It was a custom in Edinburgh for the professors to ask us students once a year to an evening party; and although some of us did not care over much for that kind of entertainment, we could not have refused if we would. I remember I was annoyed at having to buy a dress suit, when my invitation came; I thought it waste of money, and money was scarce in those days. Tommy, I've got that suit now....

"You know that I am as happily married as a man can be;" the speaker started afresh. "No husband ever had a better, a dearer, or a fonder wife—but she has never thought of inquiring into the secret of that locked drawer upstairs,—and though I shall tell it her some day, I haven't yet. It sticks in my throat, and I have put off and put off—but, anyhow, you shall hear.... I went to the party I was telling you about, and—and she was there. A colonel's daughter, and no great lady—as I was at the pains to find out afterwards. Her family was not much better than my own, and upon that I built my hopes—for we think much of family in Scotland. But hopes? I don't know that they could be called 'hopes'. I was stunned, bewildered. She was the loveliest creature I had ever seen, and Tommy"—he leaned forward, his hands clasping the chair arms on either side—"many women as I've seen since, I have never yet seen her like.... Such eyes, such a brow, such a dazzling fair skin—the curved oval of her cheek—huts! I maunder.... She was amused by my adoration, Tommy; I don't know that it even flattered her, she was so accustomed to it—and I fear, I fear she felt no pity.... At any rate I was permitted to come to the house—for I fought and struggled till I obtained an entrance,—and even what I saw there did not open my eyes. I was doing well at college, you see; oh, I had better speak out, I did a deal better than ever you did, my lad, and carried off honours which at that time seemed high enough to promise anything. I saw myself at the head of my profession, with money, position, perhaps a title—and thought if she would only wait? Had she shown, were it ever so cruelly, her real sentiments, I might have groaned beneath the knife, but the wound would have healed swiftly, as wounds do at that age—but she kept me dangling on through long months of torture, worn to skin and bone,"—he broke off abruptly, paced the room, and stood for a moment at the window with his back turned, then resumed:—

"When my sick jealousy became too apparent, she applied an opiate. A few kind words or looks, an enchanting smile, and the poor, infatuated fool was as mad as ever. We used to walk in Princes Street Gardens—I can smell the spring flowers there now."

Another pause.

"You can guess the rest, I suppose?" With an effort the speaker heaved himself upright, and a grimmer expression overcast his features. "It was all a delusion—all. There never had been anything on her side—never. Oh, she was sorry, so sorry, but really she could not blame herself. My boy, I was made to feel I was the dirt of the earth beneath her feet.... Heigho! I got over it, Tommy—in time. Not for a long, long time; not till years had come and gone." Another pause. "Those years are what I would fain save you from," said Dr. Craig, slowly.

He had been encouraged to proceed by the respectful attention of the motionless form beside him. A deep sigh, or an inarticulate murmur on the young man's part alone showed that he was following what was said, and that it struck home,—but he remained rigid, and there might even have been something of stubbornness in the set of his shoulders. What if after all he refused to learn the lesson thus sternly and withal tenderly taught? "Maybe I've wasted my breath," mentally queried the other, frowning and biting his lip. Already he was repenting himself of the confidence wrung out of him, when all in a moment the scene changed.

"My lad—my lad," he cried, for Tommy had flung himself across the table, sobbing as though his heart would break.

"So, so? I should have spoken before," muttered the doctor, half-aloud. "It's the old story of shutting the door on the empty stable.—Tommy?"
