ARGONNE, a rocky forest-clad plateau in the north-east of France, extending along the borders of Lorraine and Champagne, and forming part of the departments of Ardennes, Meuse and Marne.
The Argonne stretches from S.S.E.
There are many forests which clothe the slopes of the plateau.
The most wooded parts of France are the mountains Loire and plateaus of the east and of the north-east, comprising Seine the pine-forests of the Vosges and Jura (including the beau- Bouch~e tiful Forest of Chaux), the Forest of Haye, the Forest of Rhne Ardennes, the Forest of Argonne, &c.; the Landes, where M rth replanting with maritime pines has transformed large areas Ardenn of marsh into forest; and the departments of Var and Vos as Arige.
The other principal river, the Aisne, crosses the southern border and takes a northerly, then a westerly course, separating the region known as Champagne Pouilleuse from the more elevated plateau of Argonne which forms the central zone of the department and stretches to the left bank of the Meuse.
Dumouriez succeeded in rousing the spirit of the French; he occupied the defiles of the forest of Argonne, thus causing the enemy to lose many valuable days, and when at last they turned his position, he retreated without loss.
Cones of Lower Cretaceous age have been described by Fliche from Argonne, which bear a close resemblance to the female flowers of recent species of Cedrus.
