clinging, as it were, to sides of granite. The shingle of the old 
river bed is seen in one or two localities on the right bank 
overlying basalt, and at an elevation of 80 or 100 feet above 
the present stream. The village of Antraigues is very pic- 
turesque, situated on a lofty rock, at the foot of which flows the 
Volane in a deep rocky channel. On the path leading up to the 
village stands an isolated rock, about 30 feet high, of twisted 
basaltic columns, resting on granite. This rock is a most re-

well repays the ascent, for the view commands the Coiron 
range, and we can see the capping of basalt from the point where 
it was poured out from the granitic base near Le Grua, to flow 
away in the direction of Privas, where it covers Jurassic and Cre- 
taceous rocks, in widely-spread plateaux. On the other side
