regard to its being pretty nearly the compass direction, the 
western, and the latter the eastern side. 
Taking notice of this, which could not be done at all times on 
a journey through tracts before unexplored, I could almost be 
certain to find the normal furrows on a hill, should there be any 
there at all to be seen, and in this manner was almost sure to 
discover the principal direction of the furrows. 
For the sake of perspicuity some difference should be made 
between the normal furrows of the slopes and the side furrows; 
and with the latter between the side furrows to the right, and the 
side furrows to the left. 
I likewise found something of importance to observe, namely, 
that the same furrows may be normal furrows as belonging to a 
lesser mountain height, but likewise side furrows with respect to 
another greater height lying in the neighbourhood. Such are 
the furrows which follow the ridge of the rock sketched on Plate 
III., and which, according to the compass, had 153° normal fur- 
rows on the rock; but side furrows to the left as belonging to 
the Pilboberg. Therefore it should be remembered, that 
The normal furrows on a rock may be side furrows on a 
mountain ; 
The normal furrows of a mountain may be the side furrows 
of a higher mountain ;—as well as that 
_ The normal furrows of a large hill may be the side furrows of 
less elevated land. 
Even on a plain where the furrows generally run parallel, 
side furrows from a mountain in the neighbourhood are to be 
met with; which, for example, is the case on approaching to 
Hunneberg or Kinnekulle,from the plain of West Gothland, and 
regarding which it is necessary to be cautious that they are not 
considered of greater importance than belongs to them, for de- 
termining the direction of the furrows in a more general view. 
Another circumstance to which attention should be paid, even 
with the furrows well defined, is the texture of the mountain, as 
this is often not without influence on their direction. If the di- 
rection of the mountain is nearly the same as that of the furrows, 
as well as if the strata are composed of alternate hard and soft 
substances, it seems to me that the furrows follow the direction 
of the strata. What I am certain of, and have often seen, is, 
that it thus happens on a small scale, but I am uncertain if it be 
the case ona larger. The texture of the mountain has also its in- 
fluence on the side furrows ; for if it be coarse-granular, so that
