Here Councillor Bremen leisurely took a large pinch of snuff to refresh his memory, and with the tips of his fingers shook off the tiny particles which fell on his delicate lace jabot. Then he went on:—
"Five or six years before the revolution of 1789, a young doctor of Pirmesans, called Christian Weber, went to St. Domingo to seek his fortune. He had been very successful, and was about to retire, when the revolt of the negroes occurred. Happily he escaped the massacre, and was able to save part of his fortune. He travelled for a time in South America, and about the period of which I speak, returned to Pirmesans, and bought the house and what remained of the practice of Dr. Haselnoss.
"Dr. Christian Weber brought with him an old negress called Agatha; a very ugly old woman, with a flat nose, and enormous lips. She always enveloped her head in a sort of turban of the most startling colours; and wore rings in her ears which reached to her shoulders. Altogether she was such a singular-looking creature, that the mountaineers came from miles around just to look at her.
"The doctor himself was a tall, thin man, invariably dressed in a blue swallow-tailed coat and leather breeches. He talked very little, his laugh was dry and nervous, and his habits most eccentric. During his wanderings he had collected a number of insects of almost every species, and seemed to be much more interested in them than in his patients. In his daily rambles among the mountains he often found butterflies to add to his collection, and these he brought home pinned to the lining of his hat.
"Dr. Weber, Mr. Fritz, was my cousin and my guardian, and directly he returned to Germany he took me from school, and settled me with him at Spinbronn. Agatha was a great friend of mine, though at first she frightened me, but she was a good creature, knew how to make the most delicious sweets, and could sing the most charming songs.
"Sir Thomas and Dr. Weber were on friendly terms, and spent long hours together talking of subjects beyond my comprehension—of transmission of fluids, and mysterious things which they had observed in their travels. Another mystery to me was the singular influence which the doctor appeared to have over the negress, for though she was generally particularly lively, ready to be amused at the slightest thing, yet she trembled like a leaf if she encountered her master's eyes fixed upon her.
"I have told you that birds, and even large animals, were engulphed in the cavern. After the disappearance of the visitors, some of the old inhabitants remembered that about fifty years before a young girl, Loisa Muller, who lived with her grandmother in a cottage near the source, had suddenly disappeared. She had gone out one morning to gather herbs, and was never seen or heard of again, but her apron had been found a few days later near the mouth of the cavern. From that it was evident to all that the skeleton about which Dr. Haselnoss had written so eloquently was that of the poor girl, who had, no doubt, been drawn into the cavern by the mysterious influence which almost daily acted upon more feeble creatures. What that influence was nobody could tell. The superstitious mountaineers believed that the devil inhabited the cavern, and terror spread throughout the district.
"One afternoon, in the month of July, my cousin was occupied in classifying his insects and re-arranging them in their cases. He had found some curious ones the night before, at which he was highly delighted. I was helping by making a needle red-hot in the flame of a candle.
"Sir Thomas, lying back in a chair near the window and smoking a big cigar, was regarding us with a dreamy air. The commodore was very fond of me. He often took me driving with him, and used to like to hear me chatter in English. When the doctor had labelled all his butterflies, he opened the box of larger insects.
"'I caught a magnificent horn-beetle yesterday,' he said, 'the lucanus cervus of the Hartz oaks. It is a rare kind.'
