“ The Dordogne is the principal river of the department and its chief affluent is the Isle, which crosses the centre of the department and flows into the Dordogne at Libourne, in the neighbouring department of Gironde. The Dronne and the Auvézère, both tributaries of the Isle, are the other main rivers. The climate is generally agreeable and healthy, but rather humid, especially in the north-east. Agriculture flourishes in the south and south-west of the department, especially in the valleys of the Dordogne and Isle, the rest of its surface being covered to a great extent by woods and heath. ”
