In the rock of Dore Holm is a natural archway, 70 ft.
Dore, Old Bibles (2nd ed., 1888); J.
The principal affluents are the AriCge, the Tarn with the Aveyron and the Agout, the Lot and the Dordogne, which descends from Mont Dore-lesBains, and joins the Garonne at Bec-dAmbez, to form the Gironde.
On the right the Loire receives the waters of the Furens, the Arroux, the Nivre, the Maine (formed by the Mayenne and the Sarthe with its affluent the Loir), and the Erdre, which joins the Loire at Nantes; on the left, the Allier (which receives the Dore and the Sioule), the Loiret, the Cher, the Indre, the Vienne with its affluent the Creuse, the Thouet, and the Svre-Nantaise.
It contains many mountains volcanic in origin (Plomb du Cantal, Puy de Dome, Mont Dore), fertile valleys such as that of Limagne, vast pasturelands, and numerous medicinal springs.
