There exists in the region of Montfermeil a very ancient superstition, which is all the more curious and all the more precious, because a popular superstition in the vicinity of Paris is like an aloe in Siberia. We are among those who respect everything which is in the nature of a rare plant. Here, then, is the superstition of Montfermeil: it is thought that the devil, from time immemorial, has selected the forest as a hiding-place for his treasures. Goodwives affirm that it is no rarity to encounter at nightfall, in secluded nooks of the forest, a black man with the air of a carter or a wood-chopper, wearing wooden shoes, clad in trousers and a blouse of linen, and recognizable by the fact, that, instead of a cap or hat, he has two immense horns on his head. This ought, in fact, to render him recognizable. This man is habitually engaged in digging a hole. There are three ways of profiting by such an encounter. The first is to approach the man and speak to him. Then it is seen that the man is simply a peasant, that he appears black because it is nightfall; that he is not digging any hole whatever, but is cutting grass for his cows, and that what had been taken for horns is nothing but a dung-fork which he is carrying on his back, and whose teeth, thanks to the perspective of evening, seemed to spring from his head. The man returns home and dies within the week. The second way is to watch him, to wait until he has dug his hole, until he has filled it and has gone away; then to run with great speed to the trench, to open it once more and to seize the “treasure” which the black man has necessarily placed there. In this case one dies within the month. Finally, the last method is not to speak to the black man, not to look at him, and to flee at the best speed of one’s legs. One then dies within the year. As all three methods are attended with their special inconveniences, the second, which at all events, presents some advantages, among others that of possessing a treasure, if only for a month, is the one most generally adopted. So bold men, who are tempted by every chance, have quite frequently, as we are assured, opened the holes excavated by the black man, and tried to rob the devil. The success of the operation appears to be but moderate. At least, if the tradition is to be believed, and in particular the two enigmatical lines in barbarous Latin, which an evil Norman monk, a bit of a sorcerer, named Tryphon has left on this subject. This Tryphon is buried at the Abbey of Saint-Georges de Bocherville, near Rouen, and toads spawn on his grave.
