So 



firmly did these barnacles adhere to the gneiss, that I was

able to break off portions of tlie rock with the shells attached. 

 The face of the gneiss was also encrusted with br jozoa ; bnt 

 had these or the barnacles been exposed in the atmosphere 

 ever since the elevation of the rocks above the sea, thej 

 would doubtless have decomposed and been obliterated. 



The town of IJddevalla (see Map, p. 184) stands at the 

 head of a narrow creek overhung by steep and barren rocks 

 of gneiss, of which all the adjacent country is composed, 

 except in the low grounds and bottoms of valleys, where 

 strata of sand, clay, and marl frequently hide the funda- 



rocks. To these newer and horizontal deposits, some-

 and shallow-water dej)Osit underlaid the shells proper to 

 deeper water; a fact clearly implying a depression of the bed 

 of the sea previous to that upheaval which has since carried
