By September all the vegetation was fast crumbling to a greyish powder, and Nahum feared that the trees would die before the poison was out of the soil. His wife now had spells of terrific screaming, and he and the boys were in a constant state of nervous tension. They shunned people now, and when school opened the boys did not go. But it was Ammi, on one of his rare visits, who first realized that the well water was no longer good. It had an evil taste that was not exactly fetid nor exactly salty, and Ammi advised his friend to dig another well on higher ground to use till the soil was good again. Nahum, however, ignored the warning, for he had by that time become calloused to strange and unpleasant things. He and the boys continued to use the tainted supply, drinking it as listlessly and mechanically as they ate their meagre and ill-cooked meals and did their thankless and monotonous chores through the aimless days. There was something of stolid resignation about them all, as if they walked half in another world between lines of nameless guards to a certain and familiar doom.
Thaddeus went mad in September after a visit to the well. He had gone with a pail and had come back empty-handed, shrieking and waving his arms, and sometimes lapsing into an inane titter or a whisper about "the moving colours down there." Two in one family was pretty bad, but Nahum was very brave about it. He let the boy run about for a week until he began stumbling and hurting himself, and then he shut him in an attic room across the hall from his mother's. The way they screamed at each other from behind their locked doors was very terrible, especially to little Merwin, who fancied they talked in some terrible language that was not of earth. Merwin was getting frightfully imaginative, and his restlessness was worse after the shutting away of the brother who had been his greatest playmate.
Almost at the same time the mortality among the livestock commenced. Poultry turned greyish and died very quickly, their meat being found dry and noisome upon cutting. Hogs grew inordinately fat, then suddenly began to undergo loathsome changes which no one could explain. Their meat was of course useless, and Nahum was at his wit's end. No rural veterinary would approach his place, and the city veterinary from Arkham was openly baffled. The swine began growing grey and brittle and falling to pieces before they died, and their eyes and muzzles developed singular alterations. It was very inexplicable, for they had never been fed from the tainted vegetation. Then something struck the cows. Certain areas or sometimes the whole body would be uncannily shrivelled or compressed, and atrocious collapses or disintegrations were common. In the last stages—and death was always the result—there would be a greying and turning brittle like that which beset the hogs. There could be no question of poison, for all the cases occurred in a locked and undisturbed barn. No bites of prowling things could have brought the virus, for what live beast of earth can pass through solid obstacles? It must be only natural disease—yet what disease could wreak such results was beyond any mind's guessing. When the harvest came there was not an animal surviving on the place, for the stock and poultry were dead and the dogs had run away. These dogs, three in number, had all vanished one night and were never heard of again. The five cats had left some time before, but their going was scarcely noticed since there now seemed to be no mice, and only Mrs. Gardner had made pets of the graceful felines.
On the nineteenth of October Nahum staggered into Ammi's house with hideous news. The death had come to poor Thaddeus in his attic room, and it had come in a way which could not be told. Nahum had dug a grave in the railed family plot behind the farm, and had put therein what he found. There could have been nothing from outside, for the small barred window and locked door were intact; but it was much as it had been in the barn. Ammi and his wife consoled the stricken man as best they could, but shuddered as they did so. Stark terror seemed to cling round the Gardners and all they touched, and the very presence of one in the house was a breath from regions unnamed and unnameable. Ammi accompanied Nahum home with the greatest reluctance, and did what he might to calm the hysterical sobbing of little Merwin. Zenas needed no calming. He had come of late to do nothing but stare into space and obey what his father told him; and Ammi thought that his fate was very merciful. Now and then Merwin's screams were answered faintly from the attic, and in response to an inquiring look Nahum said that his wife was getting very feeble. When night approached, Ammi managed to get away; for not even friendship could make him stay in that spot when the faint glow of the vegetation began and the trees may or may not have swayed without wind. It was really lucky for Ammi that he was not more imaginative. Even as things were, his mind was bent ever so slightly; but had he been able to connect and reflect upon all the portents around him he must inevitably have turned a total maniac. In the twilight he hastened home, the screams of the mad woman and the nervous child ringing horrible in his ears.
