The canal of Languedoc passes through the valley of the Aude. Of course the grand idea of uniting the two seas could have originated with no less a person than Charlemagne himself. Francis the First also agitated the question. The principle on which canals are constructed was known in the Middle Ages. That universal genius, Leonardo da Vinci, was the first to make a practical application of it. In spite of this, the canal of Languedoc required a century and a half of profound study on the part of men of talent before it was decided on. The difficulty of its construction can hardly be realized in these days. It was not till the time of Louis XIV. the work was undertaken by M. de Riquet, who brought down waters from the Montagne Noire to feed the basins in the valley of the Aude. The whole canal was built in seventeen years, and cost about seventeen millions of livres. He did not live to see it opened. That satisfaction was reserved for his sons. The people awaited the day with impatience, and when it was opened, May 15, 1681, there was one great outburst of joy and admiration all the way from the Garonne to the Mediterranean. The intendant of the province, and all the capitouls of Toulouse, assembled in the morning in the cathedral of that city. The archbishop officiated. Nor was M. Riquet forgotten amid the thanksgiving. His sons were present. And

at the close of Mass, the archbishop turned and said: Brethren, let us pray for the repose of the soul of Pierre Paul de Riquet. Every head bent a few moments in silent prayer for the benefactor of the country.

A richly carpeted bark, from which floated the national colors, had been prepared. The Abbot of St. Jernin solemnly blessed the waters of the canal, and the dignitaries set out amid the applause of the multitude, followed by two other barks filled with musicians. At Castelnaudary, Cardinal de Bonzi, with several other prelates and lords, joined them in a magnificent galley, amid the noise of cannon and the peal of trumpets, followed by twenty barks full of merchandise. It was not till May 24 this flotilla arrived at Béziers, where it was hailed, as all along the way, with salutes and cries of joy. These demonstrations were warranted by the immense benefit of the canal to the country, and though now in a great measure superseded by the railway, it is still of the greatest utility.

Before the Aude reaches Carcassonne, it flows directly through the pretty, industrious town of Limoux, where the shores are connected by an old Roman bridge. Four hills enclose the charming valley, on the sides of which grow the vines that yield the blanquette of Limoux, which is famous in the wine market. On one of these hills stands a rural chapel held in great veneration by the people around—that of Notre Dame de Marceille, one of the most frequented places of pilgrimage in southern France, which has been sung by poets, studied by archæologists, and sketched by artists. Nothing could be lovelier than its situation. From the plateau

around the chapel you look down on the Flacian valley, watered by the Aude. To the west are the walls of Limoux in the midst of its vineyards and manufactories. Further off are bare cliffs and wooded hills, while on the very edge of the horizon rise, like an army of giants, the summits of the Pyrenees, almost always covered with snow or shrouded in mist. What a variety of temperature and products this landscape embraces—the cold mountain summit and the heat of the plain, verdant heights and naked rocks, the frowning hills and joyous valleys, gloomy forests of pines and frolicsome vines, fresh meadows and fields of golden grain! Through all this flows the Aude, past old legendary castles now in ruins, along marvellous grottoes a sibyl might envy, its current spanned by bridges with their tutelar Madonnas, but not disdaining to turn the wheels of the petty industries below us, though it has its source amid impassable gulfs among yonder peaks lost in the clouds.

A paved rampe leads up the hillside to Notre Dame de Marceille, more than six hundred feet long, which the pilgrims ascend on their knees, praying as they go. Half-way up, they stop to rest beside a trickling fountain and drink of the water that falls drop by drop. On the arch above is the inscription in letters of gold:

Mille mali species Virgo levavit aqua.[172]

The present church dates from 1488, but a sanctuary is known to have existed here as early as 1011. From age to age it has been the object of ever increasing veneration among the people. It belonged at one time to the abbey of St.

Hilaire, but in 1207 passed into the hands of the Dominicans of Prouilhe. You enter by a porch, which is supported by slender columns that give it an air of elegance. On the front is inscribed:

“Stay, traveller: adore God, invoke Mary.”
