108 SEFSTROM ON THE FURROWS WHICH TRAVERSE 
observations on the configuration of the land, and sketched the 
profile * extending across the country. 
The first of these follows the Dalelfven through Osterdalerne, 
as far as to Snohiattan in Norway ; thus to the westward much 
beyond what the map shows (PI. IV.), and the object of which 
has been to bring forward something which shall be explained 
hereafter. 
The second profile goes over the flat land in Eastern and 
Western Gothland. The land here is generally very low, and the 
hills which appear on the profile lie partly isolated, partly in 
connexion with the hills further to the southward ; so that they 
do not properly belong to this profile, although, from the higher 
mountain to the southward, they jut like two projecting points 
to the north, on both sides of lake Wettern. 
The third profile shows the land south of Jonképing, whence 
it quickly rises to a considerable height, and stretches itself to a 
broad plateau over the province [Lin] of Jénképing, as well as 
over a considerable part of the provinces of Wennersborg, Wexi0, 
and Calmar. 
If we now compare the second and third of these profiles, 
we find that the boulder-flood, when it passed over the 58° of 
latitude, rushed upon a hill considerably higher than that which 
it had just before passed. Besides, the greater hill was composed 
of much harder substances than those which appear in East 
Gothland, on the northern side of the Gotha Canal; and there, 
to all appearance, a considerable hill, composed of a coarse- 
grained loose granite, has been carried away by the boulder 
stream}. It is thus highly probable, although it cannot until 
after a more minute investigation be considered as decided, that 
the hill to the south of Jénképing has caused the important de- 
viations which the furrows make at Westervik and Uddevalla, 
as well as that these furrows are side furrows belonging to the 
before-menrtioned hill. 
What is further to be remarked in regard to the difference | 
in the direction of the furrows in different places, must be 
reserved until we shall have to make some reflections on the 
general direction of the boulder-flood over the whole of Scandi- 
navia. In the mean time it is probable, that however great
