He grasped it by its long, thick neck, and tried to twist the cap off; but it remained firm, which was not surprising, seeing that it was thickly coated with a lava-like crust.

"I must get some of that off first, and then try again," he decided; and after foraging downstairs, he returned with a hammer and chisel, with which he chipped away the crust till the line of the cap was revealed, and an uncouth metal knob that seemed to be a catch.

This he tapped sharply for some time, and again attempted to wrench off the lid. Then he gripped the vessel between his knees and put forth all his strength, while the bottle seemed to rock and heave under him in sympathy. The cap was beginning to give way, very slightly; one last wrench—and it came off in his hand with such suddenness that he was flung violently backwards, and hit the back of his head smartly against an angle of the wainscot.

He had a vague impression of the bottle lying on its side, with dense volumes of hissing, black smoke pouring out of its mouth and towering up in a gigantic column to the ceiling; he was conscious, too, of a pungent and peculiarly overpowering perfume. "I've got hold of some sort of infernal machine," he thought, "and I shall be all over the square in less than a second!" And, just as he arrived at this cheerful conclusion, he lost consciousness altogether.

He could not have been unconscious for more than a few seconds, for when he opened his eyes the room was still thick with smoke, through which he dimly discerned the figure of a stranger, who seemed of abnormal and almost colossal height. But this must have been an optical illusion caused by the magnifying effects of the smoke; for, as it cleared, his visitor proved to be of no more than ordinary stature. He was elderly, and, indeed, venerable of appearance, and wore an Eastern robe and head-dress of a dark-green hue. He stood there with uplifted hands, uttering something in a loud tone and a language unknown to Horace.

Ventimore, being still somewhat dazed, felt no surprise at seeing him. Mrs. Rapkin must have let her second floor at last—to some Oriental. He would have preferred an Englishman as a fellow-lodger, but this foreigner must have noticed the smoke and rushed in to offer assistance, which was both neighbourly and plucky of him.

"Awfully good of you to come in, sir," he said, as he scrambled to his feet. "I don't know what's happened exactly, but there's no harm done. I'm only a trifle shaken, that's all. By the way, I suppose you can speak English?"

"Assuredly I can speak so as to be understood by all whom I address," answered the stranger.

"Dost thou not understand my speech?"
