the coast are western hemlock of small size. Large areas on the 
mountain sides where deforestation had taken place are occupied 
by a luxuriant alder growth. The undergrowth in the forest 
is made up largely of Vaccinium ovalifolium, Rubus spectabilis, 
and Menziesia ferruginea. 
DISC ISLAND. 
Dise Island owes its name to its narrow dise-like shape. It 
is a long, high ridge of almost uniform altitude throughout the 
four miles of its length. The summit of this ridge is about 
700 feet in altitude and bare of forest growth above 500 feet. 
Below this altitude the island is fairly well forested by small 
mountain hemlock and Sitka spruce. The majority of these 
trees show conspicuous dead tops which give the forests a pecu- 
liar appearance not seen on the islands previously visited. 
Scattered through this forest are small patches of open tundra 
supporting the normal erowth of deer cabbage, heathers, gale 
and sedges. 
ELEANOR ISLAND. 
Eleanor Island is an irregular mass several times the area 
of its southern neighbor, Dise Island. Its rock formation is 
similar, being chiefly graywacke. Its ridges attain about the 
same altitude but are forested practically to their summits 
The forests, however, are heavier and with less dead standing 
timber. 
NAKED ISLAND. 
Naked Island is a very irregular mass lying a few miles 
northeast of Eleanor. It is a part of the same sunken ridge 
to which the two islets last described and also Knight Island 
belong. The rock formation is largely composed of slaty sand- 
stones and schists. Notwithstanding the prevalence of vertical 
bedding, the hills which form the central mass of the island 
are low, gently sloping masses with broad, rounded summits. 
The forests of Naked Island are similar in composition and 
luxuriance to those of Dise Island.
