THE SCANDINAVIAN MOUNTAINS. 131 
But to this action two questions appertain, to which I have not 
yet received an accurate answer. The one is, how high has the 
flood reached here? The highest mountain I visitedis the Winter- 
berg, south-east of Schandau. This basaltic crater, about 1820 
Parisian feet above the sea, had been strongly attacked and 
undermined by the boulder-flood; but to judge from appearances, 
the flood has gone over much higher mountains than are found 
in this tract. This, however, cannot be considered as certain. 
The other question is, what was its direction here? 'There are 
many evident indications that it went from north to south, as 
there are few places where we cannot plainly distinguish the re- 
sisting and the lee-sides of the mountains ; that is, if observations 
are made on the heights, without descending into the valleys 
which everywhere intersect each other, and where the flood has 
sought its way through many outlets; but as on no spot are 
distinct furrows to be discovered, and the compass was often 
disturbed by the basalt disseminated throughout the sand- 
stone, it was impossible, during the short visit which I was 
enabled to make in this nearly inaccessible tract, to determine 
with nicety the direction. Thus much, however, could be seen, 
that the deviation from the meridian is inconsiderable, and that 
the divergence is towards the south-west. 
From the Switzerland of Saxony I proceeded in a boat up the 
Elbe to Tetschen, and thence westward by land to Toplitz. On 
the latter road, we have, on the northern side, first sandstone 
with basalt, afterwards gneiss, and then porphyry. In the 
same order as these changes occur in the solid rocks, so the 
boulders alternate in the earthy stratum of the tract to the south- 
ward, and are found at a considerable distance from their ori- 
ginal situation ; but, on the contrary, very near the basalt rocks 
which remain with southern sides. We thus see from this 
that the flood has here gone southward. From Toplitz I took 
the road to this place vid Prague. As far as could be ascer- 
tained at a distance, none of the Bohemian volcanoes are of more 
recent date than the boulder-flood; nevertheless, it is uncertain 
whether this will be confirmed by a more minute investigation ; 
for my own part, I will not absolutely affirm what I could not 
personally verify. Near Prague, westward of the road, we have 
Tablizerberg, which offered great facilities for making obser- 
vations on the furrows. I remained in Prague, and made an 
excursion from thence to that mountain. It is admirably
