The eyes of Monsieur Bonticu, ordinarily so peaceful, now shot forth sparks. Turning a livid face to his antagonist, he cried aloud:

"Monsieur Pantan, in my opinion you are a puff-ball!"

This was too much. For to call a truffle-hunter a puff-ball is to call him a thing unspeakably vile. In the eyes of a true lover of truffles a puff-ball is a noisome, obscene thing; it is a false truffle. In truffledom it is a fighting word. With a scream of rage Monsieur Pantan advanced on the bulky Bonticu.

It is seldom nowadays that the Perigordians, even in their hottest moments, say the fighting word, for once a challenge has passed, retirement is impossible, and a duel is a most serious matter. By rigid rule, the challenger and challenged must meet at daybreak in mortal combat. At twenty paces they must each discharge two horse-pistols; then they must close on each other with sabers; should these fail to settle the issue, each man is provided with a poniard for the most intimate stages of the combat. Such duels are seldom bloodless. Monsieur Bonticu's lips formed some syllables. They were:

"I withdraw? Never in this life. On the contrary, not only do I not withdraw, I reiterate," bridled Monsieur Pantan.

In a requiescat in pace voice, Monsieur Bonticu said:
