At this point, as the column of unknown colour flared suddenly stronger and began to weave itself into fantastic suggestions of shape which each spectator later described differently, there came from poor tethered Hero such a sound as no man before or since ever heard from a horse. Every person in that low-pitched sitting-room stopped his ears, and Ammi turned away from the window in horror and nausea. Words could not convey it—when Ammi looked out again the hapless beast lay huddled inert on the moonlit ground between the splintered shafts of the buggy. That was the last of Hero till they buried him next day. But the present was no time to mourn, for almost at this instant a detective silently called attention to something terrible in the very room with them. In the absence of the lamplight it was clear that a faint phosphorescence had begun to pervade the entire apartment. It glowed on the broad-planked floor where the rag carpet left it bare, and shimmered over the sashes of the small-paned windows. It ran up and down the exposed corner-posts, coruscated about the shelf and mantel, and infected the very doors and furniture. Each minute saw it strengthen, and at last it was very plain that healthy living things must leave that house.

Ammi showed them the back door and the path up through the fields to the ten-acre pasture. They walked and stumbled as in a dream, and did not dare look back till they were far away on the high ground. They were glad of the path, for they could not have gone the front way, by that well. It was bad enough passing the glowing barn and sheds, and those shining orchard trees with their gnarled, fiendish contours; but thank Heaven the branches did their worst twisting high up. The moon went under some very black clouds as they crossed the rustic bridge over Chapman's Brook, and it was blind groping from there to the open meadows.

When they looked back toward the valley and the distant Gardner place at the bottom they saw a fearsome sight. All the farm was shining with the hideous unknown blend of colour; trees, buildings, and even such grass and herbage as had not been wholly changed to lethal grey brittleness. The boughs were all straining skyward, tipped with tongues of foul flame, and lambent tricklings of the same monstrous fire were creeping about the ridgepoles of the house, barn and sheds. It was a scene from a vision of Fuseli, and over all the rest reigned that riot of luminous amorphousness, that alien and undimensioned rainbow of cryptic poison from the well—seething, feeling, lapping, reaching, scintillating, straining, and malignly bubbling in its cosmic and unrecognizable chromaticism.

Then without warning the hideous thing shot vertically up toward the sky like a rocket or meteor, leaving behind no trail and disappearing through a round and curiously regular hole in the clouds before any man could gasp or cry out. No watcher can ever forget that sight, and Ammi stared blankly at the stars of Cygnus, Deneb twinkling above the others, where the unknown colour had melted into the Milky Way. But his gaze was the next moment called swiftly to earth by the crackling in the valley. It was just that. Only a wooden ripping and crackling, and not an explosion, as so many others of the party vowed. Yet the outcome was the same, for in one feverish kaleidoscopic instant there burst up from that doomed and accursed farm a gleamingly eruptive cataclysm of unnatural sparks and substance; blurring the glance of the few who saw it, and sending forth to the zenith a bombarding cloudburst of such coloured and fantastic fragments as our universe must needs disown. Through quickly re-closing vapours they followed the great morbidity that had vanished, and in another second they had vanished too. Behind and below was only a darkness to which the men dared not return, and all about was a mounting wind which seemed to sweep down in black, frore gusts from interstellar space. It shrieked and howled, and lashed the fields and distorted woods in a mad cosmic frenzy, till soon the trembling party realized it would be no use waiting for the moon to show what was left down there at Nahum's.
