although they have been locally tilted (rarely over 15°) and cut by 
normal faults. These Cretaceous and Tertiary sedimentary beds are, 
in addition, intruded by basalt and peridotites, and locally the latter 
rock has altered the coal into amorphous graphite (see graphite) or 
into anthracite or coke. | 
СТЕЗЕСКЕ!, who traveled in Greenland from 1806 to 1813, describes 
correctly the geological association of the coal, and, concerning its 
quality, says: “It is common, brown coal of a slaty texture: it burns 
very easily, but it leaves a great residium in the form of white ashes”’. 
The coal is for the most part a lignite of only mediocre grade, although 
usually rather bright and of good lustre; it breaks down readily and, 
on weathering, deteriorates rapidly. It has, on the average, perhaps 
half the calorific value of Welsh coal; it is non-coking.

The coal from the colonial coal mine at Kaersuarsuk is apparently 
of somewhat better grade and has the appearance of а fair, quite clean 
grade of sub-bituminous coal. With forced draft and special grates it 
is burned alone in the s/s Godthaab. The s/s Hans Egede uses it mixed 
with Welsh coal on ordinary grates with common draft. Probably the 
unusually good quality of the coal is due in part to the cleanness with 
which the coal can be mined, and in part to the proximity of a peridotite 
dike which has probably partially metamorphosed it. 
In a sparsely inhabited country like Greenland there is, of course, 
but little market for coal, the total consumption of the colony and its 
dependent shipping being but 4000 tons, over half of that burned 
being English coal. Greenland coal sold in 1914 for about $ 5.40 per 
ton; Welsh coal being almost $ 11. High freight rates to Europe pre- 
clude the chance of building up an export trade even if the coal were 
of better grade. In addition to the colonial mine output of some 1 600
