116 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [DeC. 5, 



when spread out in a wide valley, than when confined in a narrow 

 one. 



In many valleys my attention was so much fixed on other objects 

 that I omitted to note the occurrence of terraces, or only noted the 

 more striking and important ones : in every instance I omitted 

 many of minor importance, or of which the real character may be 

 doubtful ; thus the following list is very incomplete, and no negative 

 argument can be drawn from its omissions. 



Valleys of the Rhone and its Tributaries. — Valley of the Rhone : 

 there are great irregular terraces above Sierre, at above 1800 feet 

 elevation, which appear to have been altered and cut up by subse- 

 quent causes. 



In the valley of Evolena there is an extensive terrace at La Loet, 

 3316 feet, which may be traced down the valley for nearly two 

 miles. 



Below Vex, at 2821 feet elevation, is an extensive terrace, on 

 a portion of which stands a ruined castle. 



In the valley of Visp I noted a terrace above S. Nicholas at 

 3815 feet, another below Stalden, at 2490 feet, which is seen again 

 below Neubruck at 2470 feet. 



In Entremont, descending from the Great St. Bernard, I observed 

 a sloping terrace a little above Liddes at 4782 feet, and a succession 

 of considerable terraces between Liddes and Orsieres, at about 4350, 

 4150, 4000, and 3770 feet. 



Valleys of the Rhine and its Tributaries. — On the Vorder Rhine 

 the highest terrace is seen at St. Jacob and Tavesch at 3825 feet ; it 

 is very extensive, but irregular. Dissentis stands on a large terrace 

 at 3805 feet, which must be a continuation of the same. In 

 Medelserthal the highest terrace is at S. Rocco at about 4720 feet ; 

 there is also one at Platta at 4658 feet, which is probably part of 

 the same. There is a very distinct terrace at Medels, 4422 feet. 



Valley of Vals : on the descent from Vals to Ilanz, I observed 

 several terraces ; one at Fuors at about 3300 feet, another between 

 Fuors and Peiden at about 3 1 75 feet, and a third below Peiden at 

 about 2930 feet ; and some smaller terraces above Ilanz, which 

 stands at 2323 feet elevation. 



The Hinter Rhine : on the descent from the Splugen towards 

 Coire the terraces are numerous and well defined ; the following 

 were noted. — The highest terrace is at the village of Splugen at 

 4780 feet ; others at Sufers at 4343 feet, Ander and Dormat at 

 3113 feet, Zilhs at 2930 feet, between ZiUis and Tussis at 2770 

 feet, at Tussis at 2350 feet, at Rhazuns at 2200 feet, and at Bona- 

 duz at 2145 feet. 



In Oberhalbstein there are some traces of a terrace below Muotta 

 at 6110 feet: a terrace at Tinzen, 4230 feet, and a very large 

 terrace above Am Stein, at about 3300 feet elevation. I was much 

 interested to find an ancient moraine resting on this last-mentioned 

 terrace ; both the moraine and the terrace have been cut through 

 by the stream, affording a section in which the position of the 

 moraine on the terrace of alluvium was clearly seen. Higher up
