At first it was intensely hot, and the lamp burned dimly; but soon after he could hear a low hissing noise, and a pleasant cool stream of air began to fill the place; the heat grew less, the light burned more brightly, and he understood what was the meaning of the bellows and the long zinc tube.

For a full hour he laboured on, wondering at times, but for the most part feeling completely stunned by the novelty of his position. He filled baskets with the clay and bricks, and by degrees cleared away the heap before him, after which he had to give place to the man who had been injured, but who now crept by both the occupants of the passage, a feat only to be accomplished after they had both lain down upon their faces.

Then the prisoner’s task was changed to that of passing bricks and pails of cement, sometimes being forced to hold the light while the man deftly fitted in bricks, and made up what had been a fall, and beyond which the passage seemed to continue ten or a dozen feet.

At intervals the gang broke off work to crawl backwards out of the passage to partake of meals which were spread for them in the library. These meals were good, and washed down with plenty of spirits and water, the two servant-like women and the so-called Adela waiting on the party, everything being a matter of wonder to the prisoner, who stared wildly at the well-dressed, lady-like, girlish creature who busied herself in supplying the wants of the gang of four bricklayer-like men.

At the first meal, Mr Barclay refused food. He said that he could not eat; but he drank heartily from the glass placed at his side-water which seemed to him to be flavoured with peculiar coarse brandy. But he was troubled with a devouring thirst, consequent upon his exertions, and that of which he had partaken seemed to increase the peculiar dreamy nature of the scene. Whether it was laudanum or some other drug, we could none of us ever say for certain; but Mr Barclay was convinced that, nearly all the time, he was kept under the influence of some narcotic, and that, in a confused dreamy way, he toiled on in that narrow culvert.

He could keep no account of time, for he never once saw the light of day, and though there were intervals for food and rest, they seemed to be at various times; and from the rarity with which he heard the faint rattle of some passing vehicle, he often thought that the greater part of the work must be done by night.

At first he felt a keen sense of trouble connected with what he looked upon as his disgrace and the way he had lowered himself; but at last he worked on like some machine, obedient as a slave, but hour by hour growing more stupefied, even to the extent of stopping short at times and kneeling before his half-filled basket motionless, till a rude thrust or a blow from a brickbat pitched at him roused him to continue his task.

The drug worked well for his taskmasters, and the making of the mine progressed rapidly, for every one connected therewith seemed in a state of feverish anxiety now to get it done.

And so day succeeded day, and night gave place to night. The two servant-like women went busily on with their work, and fetched provisions for the household consumption, no tradespeople save milkman and baker being allowed to call, and they remarked that they never once found the area gate unlocked. And while these two women, prim and self-contained, went on with the cooking and housework and kept the doorstep clean, the so-called Miss Adela Mimpriss went on with the woolwork flowers at the dining-room window, where she could get most light, and the world outside had no suspicion of anything being wrong in the staid, old-fashioned house opposite Sir John Drinkwater’s. Even the neighbours on either side heard no sound.

“What does it all mean?” Mr Barclay used to ask himself, and at other times, “When shall I wake?” for he often persuaded himself that this was the troubled dream of a bad attack of fever, from which he would awaken some day quite in his right mind. Meanwhile, growing every hour more machine-like, he worked on and on always as if in a dream.
