In June the torrent of the Gabou went dry, and Gerard established his headquarters in the keeper’s house. Farrabesche had already built his farmhouse, which he called Le Gabou. Fifty masons, brought from Paris, joined the two mountains by a wall twenty feet thick, with a foundation twelve feet deep and heavily cemented. The wall, or dam, rose nearly sixty feet and tapered in until it was not more than ten feet thick at the summit. Gerard backed this wall on the valley side with a cemented slope, about twelve feet wide at its base. On the side toward the commons a similar slope, covered with several feet of arable earth, still further supported this great work, which no rush of water could possibly damage. The engineer provided in case of unusual rains an overflow at a proper height. The masonry was inserted into the flank of each mountain until the granite or the hard-pan was reached, so that the water had absolutely no outlet at the sides.

This dam was finished by the middle of August. At the same time Gerard was preparing three canals in the principal valleys, and none of these works came up to his estimated costs. The chateau farm could now be finished. The irrigation channels through the plain, superintended by Fresquin, started from the canal made by nature along the base of the mountains on the plain side, through which culverts were cut to the irrigating channels. Water-gates were fitted into those channels, the sides of which the abundance of rock had enabled them to stone up, so as to keep the flow of water at an even height along the plain.

Every Sunday after mass, Veronique, the engineer, the rector, the doctor, and the mayor walked down through the park to see the course of the waters. The winter of 1832 and 1833 was extremely rainy. The water of the three streams which had been directed to the torrent, swollen by the water of the rains, now formed three ponds in the valley of the Gabou, carefully placed at different levels so as to create a steady reserve in case of a severe drought. At certain places where the valley widened Gerard had taken advantage of a few hillocks to make islands and plant them with trees of varied foliage. These vast operations completely changed the face of the country; but five or six years were of course needed to bring out their full character. “The country was naked,” said Farrabesche, “and madame has clothed it.”

Since these great undertakings were begun, Veronique had been called “Madame” throughout the whole neighborhood. When the rains ceased in June, 1833, they tried the irrigating channels through the planted fields, and the young verdure thus nourished soon showed the superior qualities of the marciti of Italy and the meadows of Switzerland. The system of irrigation, modelled on that of the farms in Lombardy, watered the earth evenly, and kept the surface as smooth as a carpet. The nitre of the snow dissolving in these channels no doubt added much to the quality of the herbage. The engineer hoped to find in the products of succeeding years some analogy with those of Switzerland, to which this nitrous substance is, as we know, a source of perpetual riches.

The plantations along the roads, sufficiently moistened by the water allowed to run through the ditches, made rapid growth. So that in 1838, six years after Madame Graslin had begun her enterprise, the stony plain, regarded as hopelessly barren by twenty generations, was verdant, productive, and well planted throughout. Gerard had built five farmhouses with their dependencies upon it, with a thousand acres to each. Gerard’s own farm and those of Grossetete and Fresquin, which received the overflow from Madame’s domains, were built on the same plan and managed by the same methods. The engineer also built a charming little house for himself on his own property. When all was completely finished, the inhabitants of Montegnac, instigated by the present mayor, who was anxious to retire, elected Gerard to the mayoralty of the district.

In 1840 the departure of the first herd of cattle sent from Montegnac to the Paris markets was made the occasion of a rural fete. The farms of the plain raised fine beasts and horses; for it was found, after the land was cleaned up, that there were seven inches of good soil which the annual fall of leaves, the manure left by the pasturage of animals, and, above all, the melting of the snows contained in the valley of the Gabou, increased in fertility.

It was in this year that Madame Graslin found it necessary to obtain a tutor for her son, who was now eleven years of age. She did not wish to part with him, and yet she was anxious to make him a thoroughly well-educated man. Monsieur Bonnet wrote to the Seminary. Madame Graslin, on her side, said a few words as to her wishes and the difficulty of obtaining the right person to Monsieur Dutheil, recently appointed arch-bishop. The choice of such a man, who would live nine years familiarly in the chateau, was a serious matter. Gerard had already offered to teach mathematics to his friend Francis; but he could not, of course, take the place of a regular tutor. This question agitated Madame Graslin’s mind, and all the more because she knew that her health was beginning to fail.

The more prosperous grew her dear Montegnac, the more she increased the secret austerities of her life. Monseigneur Dutheil, with whom she corresponded regularly, found at last the man she wanted. He sent her from his late diocese a young professor, twenty-five years of age, named Ruffin, whose mind had a special vocation for the art of teaching. This young man’s knowledge was great, and his nature was one of deep feeling, which, however, did not preclude the sternness necessary in the management of youth. In him religion did not in any way hamper knowledge; he was also patient, and extremely agreeable in appearance and manner. “I make you a fine present, my dear daughter,” wrote the prelate; “this young man is fit to educate a prince; therefore I think you will be glad to arrange the future with him, for he can undoubtedly be a spiritual father to your son.”

Monsieur Ruffin proved so satisfactory to Madame Graslin’s faithful friends that his arrival made no change in the various intimacies that grouped themselves around this beloved idol, whose hours and moments were claimed by each with jealous eagerness.

By the year 1843 the prosperity of Montegnac had increased beyond all expectation. The farm of the Gabou rivalled the farms of the plain, and that of the chateau set an example of constant improvement to all. The five other farms, increasing in value, obtained higher rent, reaching the sum of thirty thousand francs for each at the end of twelve years. The farmers, who were beginning to gather in the fruits of their sacrifices and those of Madame Graslin, now began to improve the grass of the plains, sowing seed of better quality, there being no longer any occasion to fear drought.
