room. In the middle of the room stood a small cooking stove with 

 the chimney running straight up through the loft and roof. Just 

 inside the door was a sink, round which a dark room was constructed 

 later. 



The house was built with great care by Gundahl Knudsen in 

 the beginning of September 1906. During the first winter it was tight 

 and good; but already in the second winter the snow began U> force 

 its way in through holes in the corners. The plentiful circulation of 

 air necessitated having the stove greatly heated, but also resulted 

 in the warmth being very unevenly dislributed in the small room. 

 On one occasion — certainly out of the common — there was a differ- 

 ence in tem|)erature of 45° С between air and floor. 



The loft of the house was used for storing the tent and sledge 

 materials etc., clothes, boots and such like. 



Two smaller sheds (Depotskure) were raised close to the villa 

 for storing instruments, plant collections, paintings, tools, clothes 

 etc. These sheds were also, like the astronomical observatory, partly 

 constructed at home, but here the principle was good, as the walls 

 and floor had a comparatively small area. 



So long as the Expedition stayed at Danmarks Ilavn, the villa 

 was occupied by Bertelsen, Koch, Lundager and Wegener. This 

 arrangement was made chiefly out of regard for the astronomical, 

 magnetic and meteorological observations, which compelled Koch 

 and Wegener especially to be constantly near the instruments. It 

 was always possible, namely, that the connection between ship and 

 land might be broken or made difficult. Further, the villa stood in 

 telephonic communication with the ship (Telefon-Ledn.). 



The instruments in the villa consisted of a normal barometer, 

 normal clock, barograph and instrument for measuring the electricity 

 of the air. A brass rod, led up through the gable from the loft into 

 the open and provided at the end with a radio-tellurium point, served 

 as collector for the registering instrument in the room. 



Round the villa were grouped observatories and other arrange- 

 ments for the magnetic, astronomical, meteorological and air electri- 

 city observations, in the following manner. 



The magnetic observatory (Magn. Obs.) contained a small de- 

 clination measuring instrument. The observatory had single walls 

 with no porch and was too lightly built at home. In spite of mats 

 at the door and other lining of the observatory and in spite of a copper 

 stove skilfully constructed by Hagerup, it was found impossible 

 during the second winter to keep up a sufficiently liigh temperature 

 and the clockwork stopped. 



Stand for the magnetic theodolite (Magn. St.). Here absolute 

 determinations were made of the declination, inclination and horizon- 

 tal intensitv.
