122 SEFSTROM ON THE FURROWS WHICH TRAVERSE 
run to the south-west, and not down-hill, but ascending, and 
at many places over very steep slopes and hills, as at Carlholm, 
at Oregrund, at Harg, at Grisslehamn, on Vaddon (island), over 
Vardkasberget, and at other places. 
ce. Eastward of Carlskrona, the circumstances are nearly iden- 
tical. 
From these indications it appears probable that the boulder- 
flood did not come from the high land, but that its direction 
was over the Gulf of Bothnia and Bottenhafvet, to the south- 
west or south-south-west. 
This is contradicted indeed by the direction of the furrows 
around Fahlun and Westervik, should these be normal-furrows ; 
but if they, on a closer examination, should be found to be side- 
furrows, namely, those around Fahlun, from the high land of 
Dalecarlia, and those near Westervik to be side-furrows from 
the great heights south of Jénképing, they would then prove 
nothing against the hypothesis that the boulder-stream came 
from the north-east *. 
On the contrary, this assumption is further supported by the 
following observations :— 
d. The great collection of lakes (vattendragen) and islands: 
Wenerns, Wetterns, Gottlands, Olands, stretching to the south- 
west. The bights of the Malar stretch out in another direc- 
tion, as well as the furrows in its neighbourhood ; but these are 
continued from the Fahlun district, and become afterwards side- 
furrows to the considerable heights south of Strengniis and 
Eskilstuna. 
e. The sand-banks in the sea, south of Finngrunden, south of 
Gothland’s Sando (sand-islands), south of Géthland, and south 
of Bornholm, also have a south-westerly direction. 
jf. On the northern or resisting side of the point which the 
Swedish coast forms outside Stockholm (Roslagen and Sédertérn) 
the sea is tolerably free from rocks; whilst, on the contrary, the 
southern or lee-side of the same point is full of them. This 
does not appear so clearly on the accompanying map as on 
maps on a larger scale, provincial maps, and M. af Klint’s sea- 
chart. To judge from the new general map of Russia, the 
* A circumstance which makes it very probable that the furrows around 
Fahlun are side-furrows, is the steepness of all the mountains here on their 
eastern sides, where the slopes also are most exposed.
