INTRODUCTION. 



Fig. 19. Dwelling-house of the Expedition. 



The following buildings were repaired and erected at the station: 



The magnetic register-observatory 



The observatory for absolute magnetic determinations 



A dwelling-house 



A storehouse, to which were attached a thermometer-screen (t) and the electroscope-hut (e). 



The Magnetic Register-Observatory. 



The building was quite a plain 

 wooden house (frame-house). It was 

 sunk down into the earth as far as the 

 underlying rock would permit. (See 

 sketch Fig. 18). Some earth was 

 thrown up against the walls; but 

 owing to the lack of loose, light 

 earth, it could not be covered entirely 

 over with earth. Stones were laid upon 

 the roof to prevent its being torn off 

 by the wind. The observatory was 

 divided into two rooms. The first, more 

 northerly, was fitted up for developing; 

 the inner, more southerly, was the regis- 

 ter-room. 

 On the ground-plan are the following: 



./ii Ji> J-n ./4> indicate respectively the north, east, south and west walls. The door, (5, opens 

 into the front room, where B is the bench upon the west wall. Upon this were kept various chemicals, 

 and implements for the keeping in order 

 of the instruments. The arrow, V^ , shows 

 the direction of the ventilating air. In 

 the north outside wall some holes were 

 bored, through which the air was ad- 

 mitted under the bench in the front room, 

 where the snow, etc., that accompanied 

 it was separated from it, and the air 

 could pass through the holes in the parti- 

 tion-wall, S, in a pure condition, free 

 from snow. The snow that blew in could 

 easily be taken away from under the 

 bench. 



The door, (5 1 , led into the register- 

 room. Here were built two solid cement 



pillars upon the firm rock. They were pi g . 20 . Observation-huts at Axel0en Station. 



of the form shown in the ground-plan 



at P and P 1 . Upon them were placed the registering apparatuses, which consisted of 2 photographic 

 registering apparatuses, R and /?', with their benzine reflectors, L and Z. 1 . The 3 magnetometers 

 (variometers), D, H, and V, are respectively the declination variometer, the horizontal intensity vario- 

 meter, and the vertical intensity variometer.
