That night there was a thunderstorm, and when the professors went out to Nahum’s the next day they met with a bitter disappointment. The stone, magnetic as it had been, must have had some peculiar electrical property; for it had “drawn the lightning,” as Nahum said, with a singular persistence. Six times within an hour the farmer saw the lightning strike the furrow in the front yard, and when the storm was over nothing remained but a ragged pit by the ancient well-sweep, half-chocked with caved-in earth. Digging had borne no fruit, and the scientists verified the fact of the utter vanishment. The failure was total; so that nothing was left to do but go back to the laboratory and test again the disappearing fragment left carefully cased in lead. That fragment lasted a week, at the end of which nothing of value had been learned of it. When it had gone, no residue was left behind, and in time the professors felt scarcely sure they had indeed seen with waking eyes that cryptic vestige of the fathomless gulfs outside; that lone, weird message from other universes and other realms of matter, force, and entity.
