“Ah, madame,” said Farrabesche, “the rector, who thinks all the time about the welfare of Montegnac, has guessed the reason, but he can’t find any proof of it. Since your arrival, he has made me trace the path of the water from point to point through each ravine and valley. I was returning yesterday, when I had the honor of meeting you, from the base of the Roche-Vive, where I carefully examined the lay of the land. Hearing the horses’ feet, I came up to see who was there. Monsieur Bonnet is not only a saint, madame; he is a man of great knowledge. ‘Farrabesche,’ he said to me (I was then working on the road the village has just built to the chateau, and the rector came to me and pointed to that chain of hills from Montegnac to Roche-Vive),--‘Farrabesche,’ he said, ‘there must be some reason why that water-shed does not send any of its water to the plain; Nature must have made some sluiceway which carries it elsewhere.’ Well, madame, that idea is so simple you would suppose any child might have thought it; yet no one since Montegnac existed, neither the great lords, nor their bailiffs, nor their foresters, nor the poor, nor the rich, none of those who saw that plain barren for want of water, ever asked themselves why the streams which now feed the Gabou do not come there. The three districts above, which have constantly been afflicted with fevers in consequence of stagnant water, never looked for the remedy; I myself, who live in the wilds, never dreamed of it; it needed a man of God.” The tears filled his eyes as he said the word. “All that men of genius discover,” said Madame Graslin, “seems so simple that every one thinks they might have discovered it themselves. But,” she added, as if to herself, “genius has this fine thing about it,--it resembles all the world, but no one resembles it.”
