Barsac is not far off, well known for its fine white wines; and beyond, is Sainte Croix de Mont, a village placed on rather a bold eminence. At Preignac the little river Ciron runs into the Garonne, and brings on its current wood from the Landes. Sometimes this small stream becomes so swollen, that it overflows, and renders the road in its neighbourhood dangerous. After the battle of Orthez, the mutilated remains of the French army crossed the valley, which this river had rendered a perfect marsh, at the peril of their lives, in order to pursue their melancholy journey, flying from the British arms. Close by is Garonnelle, a port of the _Verdelais_, where, situated a little way up the country, is a famous chapel, dedicated to Notre Dame du Luc, to which pilgrims resort, on the 8th of September, from all parts of France--so great is her renown. The chapel was founded in the twelfth century, by a Countess of Foix, and re-edified by another, or, as some say, built first in 1407, under the following circumstances:-- One day, as Isabella de Foix, wife of Archambaud de Grailli, Count of Bénauge, was visiting her domains, she had occasion to pass through a wood, when suddenly the mule on which she was riding, stopped, and would not stir from the spot either one way or the other. It was found that his foot had sunk into a _very hard_ stone, to the depth of four or five inches, his iron-shod hoof imprinting a mark on the substance. The lady, much _surprised_ at such a circumstance, which could be no other than a prodigy, descended from the animal, had the stone raised, and beheld, as well as all those who accompanied her, and as all may see who visit the holy chapel raised in the wood, a perfect portrait of the blessed Virgin, where the hoof of the mule had been! This sanctuary was given in charge to the monks of the order of Grand Mont. The Huguenots pillaged and burnt the chapel, in 1562. It was again constructed, and given to the Father Celestins, in the seventeenth century; but in all its perils and dangers the miraculous stone has remained uninjured, and attracts the same veneration as ever. Perhaps it is its vicinity which has imparted such virtues to a vineyard near, which produces the far-famed "Sauterne" known throughout Europe. We came to a great many suspension-bridges on our way: the French seem to have a perfect passion for throwing them across their rivers in this region; and, it is said, not all of them are safe; as, for instance, the admired and vaunted Cubzac, which, it is now generally feared, will give way. One of these bridges is at Langon; once a very important town, and one of late much improved in commerce, in consequence of the traffic caused by the steam-boats from Bordeaux to Agen.
