FAUNAS OF SOUTHEASTERN ALASKA 315 
LITERATURE 
Casual observations on the Paleozoic rocks of southeastern Alaska 
appear in the writings of some of the travelers who visited the region 
during Russian occupation. ‘The most important of the early papers 
is one by Dr. Grewink, a Russian, who, although he never visited 
Alaska, published a paper in 18507 which contains many geographi- 
cal and some geological data concerning southeastern Alaska. This 
work is based largely on collections and data obtained by a Russian 
naval officer. The finding of a loose specimen of the Silurian fossil 
Catenipora escharoides near Sitka is reported by Grewink.? 
In 1855 Isbister published a summary of then existing knowledge 
of the geology of northwestern America, with a geological map 
which included Russian America. The data relating to south- 
eastern Alaska4 are drawn from Grewink and the “‘ Geological Appen- 
dix” to Captain Beecher’s Voyage to Behring Straits. The crude 
inaccuracy of the map made it of little or no value as a basis for 
actual work in the region. 
In 1863 Mr. W. P. Blake made a reconnaissance of the Stikine 
River and published some notes on the rocks observed.’ In 1868 Mr. 
T. A. Blake published a paper® on southeastern Alaska which con- 
tains observations on the lithologic characters of the rocks near Sitka 
and along Chatham Strait. 
The pioneer work of George W. Dawson on the Chilkoot Pass 
and Stikine River? sections in 1888, and of C. W. Hayes along the 
Taku Inlet and River in 1891,° was the first important contribution
