The Hartz. 



red sandstone and muschelkalk. Then it is not surprising to find this 

 limestone inclined upon the eastern and western declivities of the 

 highlands ; the relations between the secondary and transition forma- 

 tions are seen to the greatest advantage on the eastern side of the 

 Hartz, between Balenstadt and Blankenburg. The observer placed 

 upon an elevation facing the east, is convinced of the posterior ele- 

 vation of the Hartz, and for a moment thinks himself present at the 

 epoch of this mighty catastrophe. The red sandstone is seen re- 

 posing upon the argillaceous schist, over the older secondary beds; 

 above lies the muschelkalk which is covered by a kind of sandstone, 

 (quadersandstein) which appeared to be of tertiary formation ; thus 

 forming a triple range of hills encircling the chain, as may be seen in 

 the plate representing the superposition of the strata before Guer- 



nerode.

 thought that this addition could not but be interesting.
