254 MORTEN P. PORSILD. 
Compared with the surrounding parts of West Greenland of the 
same geognostic structure, Hare Island is rather low; only on the 
south coast does it rise to 1640 and 940 feet. It consists of basaltic and 
tufaceous layers, often inclining in various directions, and the surface 
is usually covered with extensive morainic beds with numerous 
gneissic boulders. The sea-cliffs are steep, often inaccessible, pro- 
bably owing to a rapid sinking of the shore-line. On the west 
coast, I was much surprised to see a layer of rolled basaltic boulders 
that at first sight seemed to be interbasaltic. It extended over 
a considerable distance of the shore, near 70°22’ N. Lat., but in a 
small ravine it appeared that the odd aspect was due to the different

qualities of the basaltic layers above and below the boulder-layer. 
The underlying layers had been more resistant against disintegration 
and had formed a shelf, upon which the boulders had been deposited. 
I have given some figures (figs. 2—4) of the place and I should 
recommend to geologists a closer investigation of the quaternary de- 
posits of that part of Greenland. 
Rink states that the island, seen from a distance, shows a cap 
of perpetual ice and snow, in spite of its smallness. I have not seen 
such a cap myself, and I am inclined to think that the snowfields 
must be rather small during summer. Most of the watercourses 
are found to be totally dried up, especially at that season, and I saw 
only very small streams with water in the southern parts. But in 
spring, the creeks abound with water and their eroding power has 
been very great, as they have dug out deep ravines in the morainic
