find in Trom Sund, the two former terraces resumed. I have 
been informed, however, by a gentleman of Tromsje, who has 
given some attention to the terraces of the district, that there 
are several distinctly traceable in Balsfiord, one of them at 
the height of perhaps 400 feet above the sea. 
In Trom Sund, the faces of the hills are soft and green, 
and the two terraces appear as slight, but distinct indenta- 
tions in the grassy slope, never failing to preserve to all ap- 
pearance, one relation of levels. Itis remarkable, that, while 
clear and conspicuous on both sides of this narrow sound, 
they are scarcely to be traced on either side of the interjected 
island of Tromsée. On the north-west side of the sound, be- 
hind the island, there is a faint appearance of a third terrace 
upwards of 100 feet above the second. Of the two distinct 
terraces I took a measurement with the level and staff, and 
found them to be respectively 57 and 143 feet above the 
highest tide-mark. Another observer, M. Siljestrom, has 
given measurements of them slightly different, namely, 56 
and 149 feet, and has added the elevation of a third, which I 
did not succeed in seeing, at 220 feet. 
In the range of sounds through which the post-steamer 
passes, in the sixty-ninth degree of latitude, I observed the 
two lines well marked on the green skirts of the hills, with 
scarcely any interruption. The continuity from island to 
island is very remarkable. Sometimes there is an escarp- 
ment or a line of exposed rock, to render the ancient 
sea-mark the more distinguishable. All along there seems 
to be not the slightest departure from one set of levels. 
In recesses, where perhaps little rills have brought down 
some detritus, not only these two terraces are marked, but 
several intermediate ones besides. Ata promontory of soft 
matter, called Skatoren, forming the eastern extremity of 
the island of Ringvatsée, there are at least four terraces be- 
low the higher of the two already so often alluded to, besides 
some minute and less distinct markings. On the island of 
Vorterée, at the south point, which consists of a narrow 
lofty rock, there is an object of an instructive character, 
namely, a series of terraces on one side, with a series of 
greater elevation on the other, shewing how it may depend
