prisoner. The latter looked round him quickly for a moment, a half-glimpsed panic for an instant in his eyes, then seemed to steady.

"Sire, I cannot change the sentence you will pass upon me," he said quietly, "yet do I wish well to relate once, what happened to me and what I saw. Is it permitted me to tell that from first to last?"

The Inquisitor's head bent, and Henri Lothiere spoke, his voice gaining in strength and fervor as he continued.

"Sire, I, Henri Lothiere, am no sorcerer but a simple apothecary's assistant. It was always my nature, from earliest youth, to desire to delve into matters unknown to men; the secrets of the earth and sea and sky, the knowledge hidden from us. I knew well that this was wicked, that the Church teaches all we need to know and that heaven frowns when we pry into its mysteries, but so strong was my desire to know, that many times I concerned myself with matters forbidden.

"I had sought to know the nature of the lightning, and the manner of flight of the birds, and the way in which fishes are able to live beneath the waters, and the mystery of the stars. So when these thunderclaps began to be heard in the part of Paris in which I lived, I did not fear them so much as my neighbors. I was eager to learn only what was causing them, for it seemed to me that their cause might be learned.

"So I began to go to that field from which they issued, to study them. I waited in it and twice I heard the great thunderclaps myself. I thought they came from near the field's center, and I studied that place. But I could see nothing there that was causing them. I dug in the ground, I looked up for hours into the sky, but there was nothing. And still, at intervals, the thunderclaps sounded.

"I still kept going to the field, though I knew that many of my neighbors whispered that I was engaged in sorcery. Upon that morning of the third day of June, it had occurred to me to take certain instruments, such as loadstones, to the field, to see whether anything might be learned with them. I went, a few superstitious ones following me at a distance. I reached the field's center, and started the examinations I had planned. Then came suddenly another thunderclap and with it I passed from the sight of those who had followed and were watching, vanished from view.

"Sire, I cannot well describe what happened in that moment. I heard the thunderclap come as though from all the air around me, stunning my ears with its terrible burst of sound. And at the same moment that I heard it, I was buffeted as though by awful winds and seemed falling downward through terrific depths. Then through the hellish uproar, I felt myself bumping upon a hard surface, and the sounds quickly ceased from about me.

"I had involuntarily closed my eyes at the great thunderclap, but now, slowly, I opened them. I looked around me, first in stupefaction, and then in growing amazement. For I was not in that familiar field at all, sire, that I had been in a moment before. I was in a room, lying upon its floor, and it was such a room as I had never seen before.

"Its walls were smooth and white and gleaming. There were windows in the walls, and they were closed with sheets of glass so smooth and clear that one seemed looking through a clear opening rather than through glass. The floor was of stone, smooth and seamless as though carven from one great rock, yet seeming not, in some way, to be stone at all. There was a great circle of smooth metal inset in it, and it was on it that I was lying.

"All around the room were many great things the like of which I had never seen. Some seemed of black metal, seemed contrivances or machines of some sort. Black cords of wire connected them to each other and from part of them came a humming sound that did not stop. Others had glass tubes fixed on the front of them, and there were square black plates on which were many shining little handles and buttons.

"There was a sound of voices, and I turned to find
