But beyond and parallel to the old Kander Valley, which is now 

 traversed only by a small artificially-deflected stream, viz. the 

 Glutsch, there runs, in a north-westerly direction from the conflu- 

 ence of the Kander and Simme, another, considerably broader, 

 namely the Stocken Valley, which is separated from the present 

 Glutsch Valley by a Triassic ridge and joins the Aare Valley at Belp, 

 about 12 miles below Thun (fig. 8). This Stocken Valley probably

marks the original, pre-Glacial outlet of the Kander and Simme which 

 was afterwards barred by a debris-cone ; there is, moreover, evidence 

 that at a subsequent period the two rivers discharged separately 

 into the lake, the Simtne to the N.W. of Spiez, and the Kander to the 

 S.E. of Spiez, near the village of Eaulensee. The various deflections 

 of the river-courses are shown in the plan, fig. 9, p. 380. 



As regards the abundant, and in places well exposed, fluvio-glacial 

 and interglacial deposits in the district, it will be convenient to 

 point out that the boulders and pebbles derived from the Aare, 

 Kander, and Simme drainage-areas are in the main as follows : for 

 the Aare, dark slaty gneiss, chloritic gneiss, pale protogine or 

 Grimscl granite and verrucano, in places also red marble and black 

 limestone of the Lauterbrunnen Valley ; for the Kander, Eocene slates 

 and limestone, Gasteren granite, mica-gneiss and Tavayanaz sand- 

 stone ; for the Simme, Eocene so-called ' hornfluh,' Cretaceous, 

 Neocomian, and Jurassic, and notably red dolomitic limestone, and 

 red and greenish hornstone ; and for the present joint course of the 

 Kander and Simme, rauchwacke and gypsum, of which latter a band
