An honest tradesman, relying on the power of his faith, came to him one day, and after a long introduction, informed him, that a ghost, habited in the dress of an ancient knight, frequently presented itself before him, and awakened hopes of a treasure buried in his cellar; he had often, he said, followed it, but had always been so much alarmed by a fearful noise, and a dog which he fancied he saw, that the effort had proved fruitless, and he had returned as he went. This alarm on the one hand, and the hope of acquiring riches on the other, so entirely absorbed his mind, that he could no longer apply to his trade with his former industry, and had, in consequence, lost nearly all his custom. He therefore urgently begged Oberlin would go to his house, and conjure the ghost, for the purpose of either putting him in possession of the treasure, or of discontinuing its visits. Oberlin replied, that he did not trouble himself with the conjuration of ghosts, and endeavoured to weaken the notion of an apparition in the man's mind, exhorting him at the same time to seek for worldly wealth by application to his business, prayer, and industry. Observing, however, that his efforts were unavailing, he promised to comply with the man's request. On arriving at midnight at the tradesman's house, he found him in company with his wife and several female relations, who still affirmed that they had seen the apparition. They were seated in a circle in the middle of the apartment. Suddenly the whole company turned pale, and the man exclaimed, "Do you see, sir, the count is standing opposite to you?" "I see nothing." "Now, sir," exclaimed another terrified voice, "he is advancing towards you?" "I still do not see him." "Now he is standing just behind your chair." "And yet I cannot see him; but, as you say he is so near me, I will speak to him." And then rising from his seat, and turning towards the corner where they said that he stood, he continued, "Sir Count, they tell me you are standing before me, although I cannot see you; but this shall not prevent me from informing you that it is scandalous conduct on your part, by the fruitless promise of a hidden treasure, to lead an honest man, who has hitherto faithfully followed his calling, into ruin--to induce him to neglect his business--and to bring misery upon his wife and children, by rendering him improvident and idle. Begone! and delude them no longer with such vain hopes." Upon this the people assured him that the ghost vanished at once. Oberlin went home, and the poor man, taking the hint which in his address to the count he had intended to convey, applied to business with his former alacrity, and never again complained of his nocturnal visiter. No ghost was ever more easily laid; but supposing the story to be accurately related, Oberlin's presence of mind is not more remarkable, than that the whole company should have concurred in affirming that they saw an apparition which was invisible to him.
