cliffs descend almost vertically into the sea and the waves 
have carved out many small caves. The easternmost lujavrite mass 
is the highest and steepest. It consists entirely of green ægirine- 
lujavrite and is called Agpat (“the auks”). It rises 300 meters 
from the sea as an unbroken, almost smooth wall with a slope 
of 15°. 
At the eastern end of Agpat the sandstone appears in the 
coast-cliffs. Right down at the beach a little of the old granite 
shows under the sandstone. But the lujavrite is not in direct 
contact with the sandstone; between the two lies a kakortokite 
rich in eudialyte. This rock occurs here apparently as a regular 
dyke the direction of which is north to south and its breadth 
about 100 meters. The contact relations are here of a similar 
kind to those north of Laxefjeld (Fig. 8, p. 49), except that the 
augite-syenite is wanting at Agpat. 
The kakortokite at Agpat is moderately coarse-grained; it 
does not show any differentiation into black and white sheets, 
but is throughout uniform. It is further remarkable in that it 
contains sodalite in idiomorphie crystals. It has tabular felspar 
crystals without any tendency towards parallel arrangement. 
There is no decrease in the size of grain, neither at the con- 
tact with the lujavrite nor at the contact with the sandstone, 
but near the latter contact the kakortokite contains numerous 
pegmatitic veins, which are parallel to the contact-plane. This 
pegmatite consists of felspar, nepheline, sodalite, ainigmatite 
and arfvedsonite. 
The sandstone bordering on the nepheline-syenite just east 
of Agpat is white, quartzitic and distinctly stratified; the beds 
dip about 25° towards the south-west. Along the coast-line 
the sandstone only extends for about 100 meters and it can 
be followed upwards to a height of some few hundred meters. 
So far as could be seen, this sandstone is only a large frag- 
ment and has obtained its present position in consequence of 
faulting. East of this sandstone body there is a breccia of
