The Mineral Resources of Greenland. 55 
tons in 1914, several hundred tons were mined by Eskimos. The greater 
part of the product of the colonial mine goes to the surrounding settle- 
ments. 
The colonial coal mine, opened in 1908, is situated at Kaersuarsuk 
on а vertical seacliff some 45 т (150 feet) high. The entry 13 about 
2 m (six feet) about sealevel. Not only is the coal a lenticular body, 
but the enclosing sandstones and shales are notably lenticular; for at 
the coal mine, sandstone is the principal associated rock, although but 
39 m (130 feet) west on the strike shale predominates. (See fig. 23.) 
The coallense, sufficientlythick to mine, is 165 т (440 ft) from north to 
south, and 100 m (325 ft) from east to west. The dip'is about 3° toward 
the coast (that is S. 20° Е.). The roof is a coarse arkostic sandstone 
in which are a very few thin lenticular bodies of coal. Downward it 
passes to coal with an exceedingly sharp contact. The floor is similar 
and within the coal itself are a few discontinuous parting plans of the 
same rock. In some faces, the coal pinches out, at others faults occur. 
There are also vertical clay “veins” which may possibly be decomposed 
basalt dikes. The coal is exceedingly irregular in thickness, reaching 
a maximum of 3.3 m (eleven feet), and perhaps averaging 2.5 m (eight 
feet). Films of pyrite occur on certain fracture planes. In the roof 
is a network of veinlets, some at right angles to the bedding, and other 
parallel to it, of a black, jet-like hydro-carbon. This is doubtless due 
to distillation caused by the intrusion of a peridotitic dike some 90 m 
(three hundred feet) away. 
The mine is worked by the pillar method. A white manager and 
a foreman are employed and about eight Eskimos: These latter received 
in 1914 from 300 to 500 Kroner ($ 80 to $ 135) per year, and a certain 
amount of food. The mine is worked for nine months per year; no 
work is done in December and January when the days are short; and 
for one of the spring months, there is too much water in the mine to 
permit mining. The mining costs in 1914 were $4.05 per ton. The 
coal is sorted into coarse (15 cm or 6 inches or more), 2.5—7.5 cm (1 to 
8 inch) lumps and waste. 
In 1822, Capt. Scorressy') collected sandstone with coal seams 
and coal from Neill’s Cliffs and Cape Stewart in Jameson’s Land 
on the East coast (70°20’ N. latitude). Clay ironstone is associated. 
Professor JAMESON, who examined the specimens correlated them with 
the England and Scotch coal measures while the coarse brown coal 
of Cape Brewster (E. coast 70°10’) he considered of New Sandstone 
age. He was the first apparently to recognize in this region the presence
