But to tell the truth, I watched it in such a state of fascination that I doubt if any coherent thoughts passed through my mind; so that my impressions may have been inaccurate. All that I remember clearly is a state of extreme tension. I never feel quite comfortable during a thunder-storm; and the novelty of the phenomenon increased this discomfort, for I did not know what turn it might take next. Slowly the luminous sphere crossed the edge of the Park, dipping suddenly as though the iron railings had attracted it; and now it was almost opposite our window. For a moment its impetus seemed to carry it onwards, slantingly along the terrace; then, with a dart it swung from its course and entered the window at which we stood. From its behaviour at the Park rail, I am inclined to think that it was drawn from its line of flight by the attracting power of the metal balustrade which protected the little balcony outside the window; and that its velocity carried it past the iron, so that it came to rest within the room, just over the table between us. Instinctively, both Wotherspoon and I recoiled from this flaming apparition, shrinking back as far as possible from it on either side. Beyond this movement we seemed unable to go, for neither of us stepped out of the window recess. Between us, the ball of fire hung almost motionless; but before my eyes were dazzled I saw that it was spinning with tremendous velocity on a horizontal axis; and it seemed to me that its substance was a multitude of tiny sparks whirling in orbits about its centre. Its light was like that from a spirit-lamp charged with common salt; for over it I caught a glimpse of Wotherspoon’s flinching face, all shadowed and green. As I watched the fire-ball, shading my eyes with my hands, I saw that it was slowly settling, just as a soap-bubble sinks in the air. Lower it descended and lower, still spinning furiously on its axis. Then, after what seemed an interminable period of suspense, it collided with the table. There came a dull explosion which jerked me from my feet and drove me back against a chair. I saw Wotherspoon collapse and then everything vanished in the darkness which followed the concussion. It must have been half a minute before I was able to recover from the shock and pull myself together. When I got to my feet again, I found Wotherspoon half-standing, half-leaning against the door, one panel of which had been blown out. The room was strewn with wreckage: broken glass, scattered papers, and shattered furniture. The electric lamps had been smashed by the force of the explosion.
