Monsieur de Chavigny handed his cane to Monsieur de Beaufort.  Monsieur de Beaufort placed it horizontally at the height of one foot.

“Now, Pistache, my good dog, jump the height of this cane for Madame de Montbazon.”

“But,” interposed Monsieur de Chavigny, “it seems to me that Pistache is only doing what other dogs have done when they jumped for Mademoiselle de Pons.”

“Stop,” said the duke, “Pistache, jump for the queen.”  And he raised his cane six inches higher.

The dog sprang, and in spite of the height jumped lightly over it.

“And now,” said the duke, raising it still six inches higher, “jump for the king.”

The dog obeyed and jumped quickly over the cane.

“Now, then,” said the duke, and as he spoke, lowered the cane almost level with the ground; “Pistache, my friend, jump for the `Illustrious Coxcomb, Mazarin de Piscina.’”

The dog turned his back to the cane.

“What,” asked the duke, “what do you mean?” and he gave him the cane again, first making a semicircle from the head to the tail of Pistache.  “Jump then, Monsieur Pistache.”

But Pistache, as at first, turned round on his legs and stood with his back to the cane.

Monsieur de Beaufort made the experiment a third time, but by this time Pistache’s patience was exhausted; he threw himself furiously upon the cane, wrested it from the hands of the prince and broke it with his teeth.

Monsieur de Beaufort took the pieces out of his mouth and presented them with great formality to Monsieur de Chavigny, saying that for that evening the entertainment was ended, but in three months it should be repeated, when Pistache would have learned a few new tricks.

Three days afterward Pistache was found dead —­ poisoned.

Then the duke said openly that his dog had been killed by a drug with which they meant to poison him; and one day after dinner he went to bed, calling out that he had pains in his stomach and that Mazarin had poisoned him.

This fresh impertinence reached the ears of the cardinal and alarmed him greatly.  The donjon of Vincennes was considered very unhealthy and Madame de Rambouillet had said that the room in which the Marechal Ornano and the Grand Prior de Vendome had died was worth its weight in arsenic —­ a bon mot which had great success.  So it was ordered the prisoner was henceforth to eat nothing that had not previously been tasted, and La Ramee was in consequence placed near him as taster.

Every kind of revenge was practiced upon the duke by the governor in return for the insults of the innocent Pistache.  De Chavigny, who, according to report, was a son of Richelieu’s, and had been a creature of the late cardinal’s, understood tyranny.  He took from the duke all the steel knives and silver forks and replaced them with silver knives and wooden forks, pretending that as he had been informed that
