In May the insects came, and Nahum's place became a nightmare of buzzing and crawling. Most of the creatures seemed not quite usual in their aspects and motions, and their nocturnal habits contradicted all former experience. The Gardners took to watching at night – watching in all directions at random for something – they could not tell what. It was then that they owned that Thaddeus had been right about the trees. Mrs. Gardner was the next to see it from the window as she watched the swollen boughs of a maple against a moonlit sky. The boughs surely moved, and there was no 'wind. It must be the sap. Strangeness had come into everything growing now. Yet it was none of Nahum's family at all who made the next discovery. Familiarity had dulled them, and what they could not see was glimpsed by a timid windmill salesman from Bolton who drove by one night in ignorance of the country legends. What he told in Arkham was given a short paragraph in the Gazette; and it was there that all the farmers, Nahum included, saw it first. The night had been dark and the buggy-lamps faint, but around a farm in the valley which everyone knew from the account must be Nahum's, the darkness had been less thick. A dim though distinct luminosity seemed to inhere in all the vegetation, grass, leaves, and blossoms alike, while at one moment a detached piece of the phosphorescence appeared to stir furtively in the yard near the barn.
The grass had so far seemed untouched, and the cows were freely pastured in the lot near the house, but toward the end of May the milk began to be bad. Then Nahum had the cows driven to the uplands, after which this trouble ceased. Not long after this the change in grass and leaves became apparent to the eye. All the verdure was going grey, and was developing a highly singular quality of brittleness. Ammi was now the only person who ever visited the place, and his visits were becoming fewer and fewer. When school closed the Gardners were virtually cut off from the world, and sometimes let Ammi do their errands in town. They were failing curiously both physically and mentally, and no one was surprised when the news of Mrs. Gardner's madness stole around.
It happened in June, about the anniversary of the meteor's fall, and the poor woman screamed about things in the air which she could not describe. In her raving there was not a single specific noun, but only verbs and pronouns. Things moved and changed and fluttered, and ears tingled to impulses which were not wholly sounds. Something was taken away – she was being drained of something – something was fastening itself on her that ought not to be – someone must make it keep off – nothing was ever still in the night – the walls and windows shifted. Nahum did not send her to the county asylum, but let her wander about the house as long as she was harmless to herself and others. Even when her expression changed he did nothing. But when the boys grew afraid of her, and Thaddeus nearly fainted at the way she made faces at him, he decided to keep her locked in the attic. By July she had ceased to speak and crawled on all fours, and before that month was over Nahum got the mad notion that she was slightly luminous in the dark, as he now clearly saw was the case with the nearby vegetation.
It was a little before this that the horses had stampeded. Something had aroused them in the night, and their neighing and kicking in their stalls had been terrible. There seemed virtually nothing to do to calm them, and when Nahum opened the stable door they all bolted out like frightened woodland deer. It took a week to track all four, and when found they were seen to be quite useless and unmanageable. Something had snapped in their brains, and each one had to be shot for its own good. Nahum borrowed a horse from Ammi for his haying, but found it would not approach the barn. It shied, balked, and whinnied, and in the end he could do nothing but drive it into the yard while the men used their own strength to get the heavy wagon near enough the hayloft for convenient pitching. And all the while the vegetation was turning grey and brittle. Even the flowers whose hues had been so strange were greying now, and the fruit was coming out grey and dwarfed and tasteless. The asters and golden-rod bloomed grey and distorted, and the roses and zinneas and hollyhocks in the front yard were such blasphemous-looking things that Nahum's oldest boy Zenas cut them down. The strangely puffed insects died about that time, even the bees that had left their hives and taken to the woods.
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 realised 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 unnamable. 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 horribly in his ears.
