As Slater grew older, it appeared, his matutinal aberrations had gradually increased in frequency and violence; till about a month before his arrival at the institution had occurred the shocking tragedy which caused his arrest by the authorities. One day near noon, after a profound sleep begun in a whiskey debauch at about five of the previous afternoon, the man had roused himself most suddenly; with ululations so horrible and unearthly that they brought several neighbours to his cabin--a filthy sty where he dwelt with a family as indescribable as himself. Rushing out into the snow, he had flung his arms aloft and commenced a series of leaps directly upward in the air; the while shouting his determination to reach some "big, big cabin with brightness in the roof and walls and floor and the loud queer music far away." As two men of moderate size sought to restrain him, he had struggled with maniacal force and fury, screaming of his desire and need to find and kill a certain "thing that shines and shakes and laughs". At length, after temporarily felling one of his detainers with a sudden blow, he had flung himself upon the other in a daemonic ecstasy of blood-thirstiness, shrieking fiendishly that he would "jump high in the air and burn his way through anything that stopped him." Family and neighbours had now fled in a panic, and when the more courageous of them returned, Slater was gone, leaving behind an unrecognisable pulp-like thing that had been a living man but an hour before. None of mountaineers had dared to pursue him, and it is likely that they would have welcomed his death from the cold; but when several mornings later they heard his screams from a distant ravine they realised that he had somehow managed to survive, and that his removal in one way or another would be necessary. Then had followed an armed searching party, whose purpose (whatever it may have been originally) became that of a sheriff's posse after one of the seldom popular state troopers had by accident observed, then questioned, and finally joined the seekers.
