But it was not from the tales of these sane, observant seekers that the chief terror of the ghost-mound sprang; indeed, had their experience been typical, the phenomenon would have bulked far less prominently in the local legendry. The most evil thing was the fact that many other seekers had come back strangely impaired in mind and body, or had not come back at all. The first of these cases had occurred in 1891, when a young man named Heaton had gone with a shovel to see what hidden secrets he could unearth. He had heard curious tales from the Indians, and had laughed at the barren report of another youth who had been out to the mound and had found nothing. Heaton had watched the mound with a spy glass from the village while the other youth made his trip; and as the explorer neared the spot, he saw the sentinel Indian walk deliberately down into the tumulus as if a trap-door and staircase existed on the top. The other youth had not noticed how the Indian disappeared, but had merely found him gone upon arriving at the mound.
When Heaton made his own trip he resolved to get to the bottom of the mystery, and watchers from the village saw him hacking diligently at the shrubbery atop the mound. Then they saw his figure melt slowly into invisibility; not to reappear for long hours, till after the dusk drew on, and the torch of the headless squaw glimmered ghoulishly on the distant elevation. About two hours after nightfall he staggered into the village minus his spade and other belongings, and burst into a shrieking monologue of disconnected ravings. He howled of shocking abysses and monsters, of terrible carvings and statues, of inhuman captors and grotesque tortures, and of other fantastic abnormalities too complex and chimerical even to remember. “Old! Old! Old!” he would moan over and over again, “great God, they are older than the earth, and came here from somewhere else — they know what you think, and make you know what they think — they’re half-man, half-ghost — crossed the line — melt and take shape again — getting more and more so, yet we’re all descended from them in the beginning — children of Tulu — everything made of gold — monstrous animals, half-human — dead slaves — madness — Iä! Shub-Niggurath! — that white man — oh, my God, what they did to him! . . .”
Heaton was the village idiot for about eight years, after which he died in an epileptic fit. Since his ordeal there had been two more cases of mound-madness, and eight of total disappearance. Immediately after Heaton’s mad return, three desperate and determined men had gone out to the lone hill together; heavily armed, and with spades and pickaxes. Watching villagers saw the Indian ghost melt away as the explorers drew near, and afterward saw the men climb the mound and begin scouting around through the underbrush. All at once they faded into nothingness, and were never seen again. One watcher, with an especially powerful telescope, thought he saw other forms dimly materialise beside the hapless men and drag them down into the mound; but this account remained uncorroborated. It is needless to say that no searching-party went out after the lost ones, and that for many years the mound was wholly unvisited. Only when the incidents of 1891 were largely forgotten did anybody dare to think of further explorations. Then, about 1910, a fellow too young to recall the old horrors made a trip to the shunned spot and found nothing at all.
By 1915 the acute dread and wild legendry of ‘91 had largely faded into the commonplace and unimaginative ghost-tales at present surviving — that is, had so faded among the white people. On the nearby reservation were old Indians who thought much and kept their own counsel. About this time a second wave of active curiosity and adventuring developed, and several bold searchers made the trip to the mound and returned. Then came a trip of two Eastern visitors with spades and other apparatus — a pair of amateur archaeologists connected with a small college, who had been making studies among the Indians. No one watched this trip from the village, but they never came back. The searching-party that went out after them — among whom was my host Clyde Compton — found nothing whatsoever amiss at the mound.
The next trip was the solitary venture of old Capt. Lawton, a grizzled pioneer who had helped to open up the region in 1889, but who had never been there since. He had recalled the mound and its fascination all through the years; and being now in comfortable retirement, resolved to have a try at solving the ancient riddle. Long familiarity with Indian myth had given him ideas rather stranger than those of the simple villagers, and he had made preparations for some extensive delving. He ascended the mound on the morning of Thursday, May 11, 1916, watched through spy glasses by more than twenty people in the village and on the adjacent plain. His disappearance was very sudden, and occurred as he was hacking at the shrubbery with a brush-cutter. No one could say more than that he was there one moment and absent the next. For over a week no tidings of him reached Binger, and then — in the middle of the night — there dragged itself into the village the object about which dispute still rages.
