Loire

Loire, the largest river in France, 630 m., rises in the Cévennes, flows northwards to Orleans and westward to the Bay of Biscay, through a very fertile valley which it often inundates. It is navigable for 550 m., but its lower waters are obstructed by islands and shoals; it is connected by canals with the Seine, Saône, and Brest Harbour.
