to tell a stolid city man about the way the great, overgrown mourning-cloak butterflies behaved in connection with these saxifrages. April brought a kind of madness to the country folk, and began that disuse of the road past Nahum's which led to its ultimate abandonment. It was next the vegetation. All the orchard trees blossomed forth in strange colours, and through the stony soil of the yard and adjacent pasturage there sprang up a bizarre growth which only a botanist could connect with the proper flora of the region. No sane wholesome colours were anywhere to be seen except in the green grass and leafage; but everywhere were those hectic and prismatic variants of some diseased, underlying primary tone without a place among the known tints of earth. The "Dutchman's breeches" became a thing of sinister menace, and the bloodroots grew insolent in their chromatic perversion. Ammi and the Gardners thought that most of the colours had a sort of haunting familiarity, and decided that they reminded one of the brittle globule in the meteor. Nahum ploughed and sowed the ten-acre pasture and the upland lot, but did nothing with the land around the house. He knew it would be of no use, and hoped that the summer's strange growths would draw all the poison from the soil. He was prepared for almost anything now, and had grown used to the sense of something near him waiting to be heard. The shunning of his house by neighbours told on him, of course; but it told on his wife more. The boys were better off, being at school each day; but they could not help being frightened by the gossip. Thaddeus, an especially sensitive youth, suffered the most.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 all 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
