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 whisky 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 neighbors 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 demoniac 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 neighbors had now fled in a panic, and when the more courageous of them returned, Slater was gone, leaving behind an unrecognizable pulp-like thing that had been a living man but an hour before. None of the 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 realized 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.
On the third day Slater was found unconscious in the hollow of a tree, and taken to the nearest jail, where alienists from Albany examined him as soon as his senses returned. To them he told a simple story. He had, he said, gone to sleep one afternoon about sundown after drinking much liquor. He had awaked to find himself standing bloody-handed in the snow before his cabin, the mangled corpse of his neighbor Peter Slader at his feet. Horrified, he had taken to the woods in a vague effort to escape from the scene of what must have been his crime. Beyond these things he seemed to know nothing, nor could the expert questioning of his interrogators bring out a single additional fact.
That night Slater slept quietly, and the next morning he wakened with no singular feature save a certain alteration of expression. Doctor Barnard, who had been watching the patient, thought he noticed in the pale blue eyes a certain gleam of peculiar quality, and in the flaccid lips an all but imperceptible tightening, as if of intelligent determination. But when questioned, Slater relapsed into the habitual vacancy of the mountaineer, and only reiterated what he had said on the preceding day.
On the third morning occurred the first of the man's mental attacks. After some show of uneasiness in sleep, he burst forth into a frenzy so powerful that the combined efforts of four men were needed to bind him in a straitjacket. The alienists listened with keen attention to his words, since their curiosity had been aroused to a high pitch by the suggestive
