Then the thing happened; the thing which to this hour makes the fabric of space with its unknown forces seem an insecure and eery garment for the body of man. Over the slight rise beyond the tree, as the air crackled, roared and shook under the thunder-blasts, there appeared an object moving in long, leisurely bounds, drifting before the wind, and touching the ground lightly each time. It was about eighteen inches in diameter, globular, glowing with coruscating fires, red, green, and yellow; a thing of unearthly and wholly sinister beauty. Alice poised with one foot half raised, and shrieked at Tristan, half terrified, half elated at the sight. He wheeled quickly, there under the tree, and slowly backed away as the thing drifted in to keep him company in his shelter. We could not see his face, but there was a stiffness to his figure indicating something like fear. Suddenly things I had read rose into my memory. This was one of those objects variously called "fire-balls," "globe-lightning," "meteors," and the like. I also recalled the deadly explosive potencies said to be sometimes possessed by such entities, and called out frantically: "Tristan! Don't touch it! Get away quickly, but don't disturb the air!" He heard me and, as the object wavered about in the comparative calm under the tree, drifting closer to him, started to obey. But it suddenly approached his face, and seized with a reckless terror, he snatched off his hat and batted at it as one would at a pestilent bee. Instantly there was a blinding glare, a stunning detonation, and a violent air-wave which threw me clear off my feet and to the ground. I sat up blindly with my vision full of opalescent lights and my ears ringing, unable to hear, see, or think. * * * * * Slowly my senses came back; I saw Alice struggling upright in the grass before me. She cast a quick glance toward the tree, then, still on her knees, covered her face and shuddered. For a long time, it seemed, I gazed toward the tree without sight conveying any mental effect whatever. Quite aside from my dazed state, the thing was too bizarre; it gave no foothold to experience for the erection of understanding. My brother's body lay, or hung, or rested--what term could describe it?--with his stomach across the _under_ side of a large limb a few feet above where he had stood. He was doubled up like a hairpin, his abdomen pressed tightly up against this bough, and his arms, legs and head extended stiffly, straightly, skyward.
