Now before the actual ascent of the crater, with its many serious difficulties, was attempted, there was one way which offered an opportunity of reconnoitering the interior, without clambering up the precipices. In the first days of September of that memorable year, a well-known aeronaut named Wilker came to Morganton with his balloon. By waiting for a breeze from the east, he could easily rise in his balloon and drift over the Great Eyrie. There from a safe height above he could search with a powerful glass into its deeps. Thus he would know if the mouth of a volcano really opened amid the mighty rocks. This was the principal question. If this were settled, it would be known if the surrounding country must fear an eruption at some period more or less distant. The ascension was begun according to the programme suggested. The wind was fair and steady; the sky clear; the morning clouds were disappearing under the vigorous rays of the sun. If the interior of the Great Eyrie was not filled with smoke, the aeronaut would be able to search with his glass its entire extent. If the vapors were rising, he, no doubt, could detect their source. The balloon rose at once to a height of fifteen hundred feet, and there rested almost motionless for a quarter of an hour. Evidently the east wind, which was brisk upon the Surface of the earth, did not make itself felt at that height. Then, unlucky chance, the balloon was caught in an adverse current, and began to drift toward the east. Its distance from the mountain chain rapidly increased. Despite all the efforts of the aeronaut, the citizens of Morganton saw the balloon disappear on the wrong horizon. Later, they learned that it had landed in the neighborhood of Raleigh, the capital of North Carolina. This attempt having failed, it was agreed that it should be tried again under better conditions. Indeed, fresh rumblings were heard from the mountain, accompanied by heavy clouds and wavering glimmerings of light at night. Folk began to realize that the Great Eyrie was a serious and perhaps imminent source of danger. Yes, the entire country lay under the threat of some seismic or volcanic disaster. During the first days of April of that year, these more or less vague apprehensions turned to actual panic. The newspapers gave prompt echo to the public terror. The entire district between the mountains and Morganton was sure that an eruption was at hand. The night of the fourth of April, the good folk of Pleasant Garden were awakened by a sudden uproar. They thought that the mountains were falling upon them. They rushed from their houses, ready for instant flight, fearing to see open before them some immense abyss, engulfing the farms and villages for miles around. The night was very dark. A weight of heavy clouds pressed down upon the plain. Even had it been day the crest of the mountains would have been invisible.
