The compass course towards the Pole NW^N 

 was referred to Dec. 16*^ 5'^ 15"" p. m. Fram- 

 heim apparent time. The Sun's hour-angle or 

 azimuth was then 15° 02' East, or t'*o™.i. 

 Noon followed at 6^ is'".! apparent Time Fram- 

 heim. The longitude of Framheim is 196° 23' 

 E. Gr. or 13'^ 5^.6. Hence the longitude of 

 Station in 89^54 equals 6'' 5o"\5 or 102° 37'. 5 

 E. Gr. The angle at the Pole is6i0 4i'7. This 

 subtracted from 102° 37'.5 gives 40° 55'. 8 as 

 the longitude of the station in lat. 89*^ 58'. 4 or 

 2*^43»\7 E. Gr. 



The diagram shows the position of the 

 stations marked by small rings, the polar tri- 

 angle, and the route from and to lat. 89*^ 37'. 

 Mr. Alexander's positions are marked with 

 crosses. The distances between our positions 

 are only 0^.4 or 0.75 kilometres. 



The compass-bearings of the Sun give the 

 magnetic declination 



at Station 89^54' 118ON— W. 



89 58 58ON— W. 

 The south and of the magnetic needle always points, from P'ramheim to the 

 South Pole, towards the South Magnetic Pole. 



On the return journe}^ to Framheim, the Expedition followed, with 

 very few deviations, the route to the Pole, marked by the beacons erec- 

 ted on the way. No astronomical observations were taken. 



The positions of the stations from lat. 89^54' to lat. 88° 30' were com- 

 puted from the general course 3049'N — E, the colatitude 1^30', and the 

 distance from the station in lat. 88*^ 30'. 



The first remarkable deviation occurred on the 2'^'^January, 1912, when 

 thick weather caused the Expedition to pass depot IX in lat. 86^22', and 

 brought it half a degree of longitude or 2 miles farther westwards than on 

 the track southwards. The former track was speedily found again.
