His next act was to purchase a dog from one of his keepers. With this animal, which he called Pistache, he was often shut up for hours alone, superintending, as every one supposed, its education. At last, when Pistache was sufficiently well trained, Monsieur de Beaufort invited the governor and officers of Vincennes to attend a representation which he was going to have in his apartment. The party assembled, the room was lighted with waxlights, and the prisoner, with a bit of plaster he had taken out of the wall of his room, had traced a long white line, representing a cord, on the floor. Pistache, on a signal from his master, placed himself on this line, raised himself on his hind paws, and holding in his front paws a wand with which clothes used to be beaten, he began to dance upon the line with as many contortions as a rope-dancer. Having been several times up and down it, he gave the wand back to his master and began without hesitation to perform the same evolutions over again. The intelligent creature was received with loud applause. The first part of the entertainment being concluded Pistache was desired to say what o’clock it was; he was shown Monsieur de Chavigny’s watch; it was then half-past six; the dog raised and dropped his paw six times; the seventh he let it remain upraised. Nothing could be better done; a sun-dial could not have shown the hour with greater precision. Then the question was put to him who was the best jailer in all the prisons in France. The dog performed three evolutions around the circle and laid himself, with the deepest respect, at the feet of Monsieur de Chavigny, who at first seemed inclined to like the joke and laughed long and loud, but a frown succeeded, and he bit his lips with vexation. Then the duke put to Pistache this difficult question, who was the greatest thief in the world? Pistache went again around the circle, but stopped at no one, and at last went to the door and began to scratch and bark. “See, gentlemen,” said M. de Beaufort, “this wonderful animal, not finding here what I ask for, seeks it out of doors; you shall, however, have his answer. Pistache, my friend, come here. Is not the greatest thief in the world, Monsieur (the king’s secretary) Le Camus, who came to Paris with twenty francs in his pocket and who now possesses ten millions?” The dog shook his head. “Then is it not,” resumed the duke, “the Superintendent Emery, who gave his son, when he was married, three hundred thousand francs and a house, compared to which the Tuileries are a heap of ruins and the Louvre a paltry building?” The dog again shook his head as if to say “no.” “Then,” said the prisoner, “let’s think who it can be. Can it be, can it possibly be, the ‘Illustrious Coxcomb, Mazarin de Piscina,’ hey?” Pistache made violent signs that it was, by raising and lowering his head eight or ten times successively.
