Note 266 — BATTLE OF ORTHEZ.

The Adour, like the Gave, is a name common to many rivers in the Pyrenees, both simply meaning water in some of those primeval languages, the remains of which are still widely preserved in the appellations of rivers and mountains. The greater and noted stream, into which the others are received, has its sources in the county of Bigorre, under the Pics du Midi and d’Espade, two of the highest mountains in the chain; it passes by Campan, Bagnères, Montgaillard, and Tarbes, and begins to be navigable near Grenade, a small town in the little county of Marsan. Having been joined by the Douze on the right below Tartas, it inclines to the south-west from its junction, passes Acqs, and then holds an almost southerly course to meet the Gave de Pau, which brings with its own waters those of the Gave d’Oleron, into which the Gave de Mauleon has been received. The Adour is then joined by the Bidouse, and lastly by the Nive.
