Relative Level of Sea and Land in Scandinavia. 69 
These banks, for several miles from the embrochure of the 
stream, are composed of terraces of clayey alluvium, rising 
above each other to the height of several hundred feet. In some 
instances, I succeeded in ascertaining that these were of cor- 
responding heights on the different sides of the river. Some 
of them persevere for several miles along the valley at one 
uniform height. I therefore considered them as roughly in- 
dicative of stages or pauses in the change of the relative level 
of sea and land. Taking as a basis the surface of the sea, 
which is here at its mean level, I found, by careful measure- 
ment with the level and the staff, that two of the most dis- 
tinct and persistent of these terraces were respectively of 
these heights, namely, 77 and 98 feet; taking in both in- 
stances that point in the sectional outline of the terrace, where 
the moderate inclination of its surface gives place to a new 
rise. A very distinct portion of this latter terrace runs along 
under a country-house called Nystad, and towards one called 
Rudd House. 
The valleys of those affluents of the Glommen River, which 
are crossed on the road from Christiania to Trondheim, are 
full of alluvial terraces of various materials. That of the 
Nytte River presents terraces of sand; that of the Leer 
River (a different river from the Lir above mentioned) affords 
terraces of clay ; and hence, no doubt, the name given to the 
stream. The appearance of these terraces, broken into short 
spaces by side streams, and often having farmsteads perched 
on the detached pieces, while the banks in front descend 
at a deep inclination to the bottom of the valley, produces 
scenery of a peculiar and striking kind. The pass from this 
valley to the next, in which runs the river issuing from the 
Midsen Lake, is a broad flat space composed of a bed of water- 
worn gravel, with pieces as large as a man’s head ; and this 
flat is several hundred feet above the level of the sea. 
The valley, containing the river issuing from the Midsen 
Lake, is several miles broad, between hills of no great ele- 
vation ; yet it is filled from side to side with a formation, at 
least topped with pure sand, generally flat, and extending 
with a slight rise up to the lower extremity of the lake, which
