The mountains rising steeply to the south of Bagnères render the place cool in summer, when some of the sun is cut off; but it is a dreary residence in the winter, for the same reason. There are springs of various temperatures and mineral components, ferruginous, sulphurous, etc., advertised as good for nearly every complaint under the sun. It was the Roman Aquæ Convenarum, and visitors may now bathe in the marble basins in which Gallo-Roman ladies and gentlemen dipped. Bagnères was always a town, and in the Hôtel de Ville are preserved archives containing much relative to the history of the place; among these is a charter of Esquirat, Count of Bigorre, confirming the customs and liberties of Bagnères, dated 1251. The history of the town is one of untroubled serenity till the times of the Wars of Religion. Captain Lizier, the Huguenot, on occupying Tarbes, imposed a heavy subsidy on the neighbouring towns, Bagnères included. But Bagnères demurred to raising the contribution demanded. Lizier marched to it, got hold of the governor, Beaudéan, and shot him. The people of Bagnères resolved on revenge. They drew the terrible captain into an ambuscade and killed him to the shout of “Remember Beaudéan!” On the summit of the Pic du Midi is an observatory, erected by the energy of two men: Vaussenat and General Nansouty. Vaussenat was a native of Grenoble, born of a labouring family in 1837. He was admitted into the school of arts, and traded at Aix, and on leaving it was engaged in search for metals in Savoy. But summoned to the Pyrenees to manage some mines there, he married a niece of a general at Bagnères, and settled there. He saw, what indeed others had seen before him, that the Pic was admirably suited for a meteorological observatory, but he could not induce the Government to take any steps towards its construction. However, he managed to communicate his enthusiasm to General Nansouty, and between them the foundations were laid and the work was begun. The general took up his abode in the cabin of Sencours, just below the terminal cone, where he passed winter and summer registering his observations, whilst Vaussenat travelled through France, lecturing, exhorting, wringing money for the work out of learned societies and from generous individuals. Nansouty underwent great hardships. On one occasion, in December, 1874, a furious tempest burst over the refuge of Sencours, and twelve feet of snow was heaped on the roof, one of the windows was blown in, and the door gave way. It was absolutely necessary to quit the place. Nansouty, aided by his two companions, took seventeen hours struggling through the snow to reach the bottom, a distance that can easily be mounted in two hours and a half.
