“ Descending rapidly from its source, sometimes over cascades, the river soon enters deep gorges through which it flows as far as Beaulieu (department of Corrèze) where it debouches into a wide and fertile valley and is shortly after joined by the Cère. Entering the department of Lot, it abandons a south-westerly for a westerly course and flowing in a sinuous channel traverses the department of Dordogne, where it receives the waters of the Vézère. ”
