a territory or county of France, in the province of Gascony. It is bounded on the east by the valley of Aure, the vicounty of Neuboula, Riviere Verdun, and Pardiac; by Bearn on the west; on the south, by the valleys of Broton and Penticouze in Arragon; and on the north, by the county of Riviere-Bas incorporated with Armagnac. It is 40 miles long from north to south, and 30 in breadth from east to west. It is divided into three parts, the mountains, the plains, and the ruffan. The mountains are inclosed between those of the valley of Aude on the east, those of Arragon on the south, and of Bearn on the west. This part contains two principal valleys, Lavedan and Barege. The valley of Bigorre is of an oval form, and has the hills of Ruffan on the east. The remarkable towns are Tarbes the capital, Bagneres, Lourd, &c. The mountains are a barrier between France and Spain, and there are four different passageways which the inhabitants are obliged to guard. Bigorre yields marble, jasper, stone, and slate; there are also mines of several sorts, but they are not worked. The rivers are the Adour, the Echez, the Arroset, and the Gave de Lavedan; there are also three lakes.
