Excerpt from Wanderings by Southern Waters: Eastern AquitaineI now left the Dordogne and ascended the valley of the Ouysse. This stream is one of the most remarkable of the natural phenomena of France. To judge from its breadth near the mouth, one would suppose that it had ¿owed fifty or a hundred miles, but its entire length is less than ten miles. It is already a river when it rises out of the depths of the earth. The narrow valley that it waters is a gorge 500 or 600 feet deep through the greater part of its distance. The traveller at the bottom sup poses, or is ready to suppose, that he is in some ravine of the high mountains in reality, it is simply a fissure of the plateau that was once the bed of the sea There is no igneous, no metamorphic rock here, nothing but limestone of the jurassic forma tion. The convexities on one side of the fissure correspond with marked regularity to the concavities on the other.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
