THE JURASSIC COAL OF STITZENBERGEN 93 



fessor Nathorst is inclined to refer the coals on the westerly side to 

 the Tertiary ; but there seem to be no differences between the 

 rocks on the two sides of the bay ; the sandstones bear the 

 same markings and the curious ferruginous concretions are as 

 characteristic on the westerly as on the easterly side. Col- 

 lections made by D. H. Morris and A. E. Stevenson on the 

 plateau between Advent and Coal bays, a distance of about ten 

 miles, as well as along the southerly side of Icefiord between 

 those bays, show the same features throughout ; so that one 

 appears to be justified in regarding all as of the same age and 

 in referring all the coals of Advent bay as well as that on Coal 

 bay to the Jurassic, in accordance with Professor Nathorst's 

 determination for the beds on the easterly side. 



While, along the line followed by Messrs, Stevenson and 

 Morris, only Jurassic beds were seen, it is necessary to go east- 

 ward but a short distance to reach Tertiary beds, of which some 

 knobs remain well-marked at not more than seven miles from 

 Advent bay. These flaggy, grayish standstones are loaded 

 with leaves of dicotyledons, with which occur stems of horse- 

 tails and apparently leaves of cycads. The succeesion through- 

 out appears to be conformable and the passage from Jurassic to 

 Tertiary seems to be very gradual. 



The effort to mine the Fangen coal in commercial quantities, 

 if successful, will be of more than passing interest. The market 

 is ample in northern Norway, where the coal can be placed at 

 less cost than that from England. The long wintry night and 

 the closing of the harbor by ice during nine months each year 

 seem almost prohibitory. But the company, in case the test be 

 satisfactory, purposes to make new openings at a more favor- 

 able point further up the bay, to erect comfortable dwellings 

 and to instal a complete electric plant, so that the work may 

 continue uninterruptedly throughout the year. The proposition 

 is by no means chimerical, as some might suppose. The 

 average January temperature is said to be not lower than 15° 

 F. and evidently Advent bay is less cold than other places not 

 more than a few miles away. On the northerly side of Icefiord, 

 about eight miles from the Advent bay anchorage, a continuous
