Relative Level of Sea and Land in Scandinavia. 75 
Trondhiem. This is the more likely, from what may be ob- 
served at Soknaes, the next post-station in the valley. 
There is here a wide space formed by the junction of a 
branch valley. The whole space within sight might be de- 
scribed as a nest of alluvial terraces, reaching to a consider- 
able height above the two rivers. At one spot, near Sok- 
naes, aS Many as six are seen rising above each other, the 
inn being placed on a promontory formed by the fourth of 
the series. A connection between this group of terraces and 
that at Vollan is obscurely traceable along the valley. By 
M. Von Buch, the elevation of the Soknaes station is set 
down at 487 feet ; and hence, I presume, that the sixth or 
highest terrace at that place may be about the same eleva- 
tion with the Trondheim line of erosion, or 522 feet. It is de- 
sirable that a careful examination of the whole of the Gula 
markings should be made, and their levels ascertained, in 
order to ascertain how far they observe uniformity, and if any 
of them be truly identical in elevation with the Trondheim 
terrace of erosion, as here surmised from observations which 
I am sorry to find so much more vague than was to be desired. 
On the Sokna, the branch of the Gula here spoken of, there 
is a similar system of alluvial terraces, on one of which the 
church of Soknadalen and post-station of Hof are situated. 
It may be remarked, however, that such terraces, though 
evidencing a shift of the relative level of sea and land, are 
not always exact marks of the point at which the sea and land 
formerly met. Where found sloping in the line of the val- 
ley, as is the case with several at Hof, they may be regarded 
as only the ancient haughs of the river before the with- 
drawal of the sea (so to speak) allowed it to cut down its 
alluvial deposit, and seek a lower channel. Where, on the 
other hand, an alluvial terrace is of the character of that at 
Vollan, not only broad and flat, but extending a long way 
upon one level, experience teaches me to expect such relations 
of measurement as indicate its being the true mark of an 
ancient line of coast. Among the Soknadalen terraces, I 
find that I have noted that on which the post-station and 
church are situated as alone answering the requirements of 
an ancient sea-level, making the additional remark, that the
