strata of the Rocks at Cluse. 

 a. Highly inclined rock overhanging the river, under which there is a narrow walk and wall 

 at b. c. The parapet of the bridge. d, A tongue of land jutting into the river, e. The 

 river Arve, which comes from behind the rock ; at the foot of which is the tongue of land 

 and the town of Cluse ; the latter represented by three gable roofs of houses, and a wall 

 round. /, Trees feathering the whole surface of the rocks on the right-hand side, g. Road- 

 way from Cluse to Bonneville. — N.B. The Valley of Maglanz is at right angles to the valley 

 in which the country between it and Bonneville is situated. 



At Cluse (Jig, VS.)? the rocks are so curved that they over- 

 hang the river and road ; and, near Cluse, the mountains are 

 split from top to bottom, forming the Vale of Reposoir ; and the 

 same singularities are remarked at various places throughout 

 the Valley of Maglanz. It had been my intention to draw up 

 a paper on this valley, as offering some peculiarly interesting 

 geological features ; but the design was abandoned, from a 

 pressure of more serious matters. The remarks of J. R. have 

 reminded me, however, of it, and I shall add a few observ- 

 ations from my note book. As confirmatory of the views I 

 have taken on the point, I may quote, at once, the words of 

 MM. Barbe and Robert; who travelled through Lorraine 

 and Switzerland in 1830, and published their observations in 

 the Bulletin de la Societe Geologique de France^ 16mo, tom. i. 

 p. 89. : — "La montagne schisteuse est singulierement repliee, 

 d*ou se precipite la cascade d'Arpenaz, la suivante, formee 

 d'ardoise, enfin une troisieme situee entre elles, au fond d'une 

 petite gorge, forment par les directions de leurs couches, re- 

 presentees par des lignes droites, un veritable triangle place 

 obliquement sur une de ses pointes." Nant d'Orli is the fall 

 alluded to in the latter part of this observation ; and the first 

 grand variation from the horizontal position of the strata which 

 occurs, is at Nant d'Orli. This is a beautiful cascade, which 

 tumbles down the face of the rocks immediately behind the 

 little village of Maglanz, from which it sometimes is called 

 the Cascade of Maglanz. {Jig- 74.) The height of the fall may 

 be about 500 ft. : it is not of any great breadth, but the water
