Fra det Punkt, hvor Theodoliten var opstillet foran 

 Magnetometret, kunde Poldetind ikke sees paa Grand af. 

 at et nærmere liggende Kjekl kom i Vejen. Men fra et 

 nærliggende Punkt paa Skjæret, i SSE for det første, vår 

 Poldetind synlig. Paa Øen. hvor Teltet stod. saaes Polde- 

 tind i samme Vertikal som Observatiouspunktrt paa Skjæret, 

 naar Theodoliten flyttedes, lodret paa Synslinien til Polde- 

 tind. 41.4 Meter mod SE fra Observationspunktet i Teltet. 

 Heraf beregnes, at Azimut af Poldetind: seet fra Theodo-

Fra den søndre Ende af Skjæret saaes en anden

 tionspunktet paa Skjæret saaes Varden paa Busø L82° 27'

 Varde (i SW) og Poldetind (i NE) regnet over Nord var 

 følgelig 192" 52'. Da Poldetinds Azimut var N 48" 0' É.

[i. An Islet at the east side of the Harbour. 

 Declination. June 16. Observer Professor Mohn. 



From the point at which the theodolite was mounted 

 in front of the magnetometer. Poldetind could not be 

 sighted. a mountain in the vicinity iiitercepting the view 

 in that direction. Poldetind was visible however from an 

 adjacent point south-south-east of the former. From the 

 island on which was pitched. the tent. Poldetind could be 

 sighted in the same vertical as the point of observation on 

 the islet. after moving the theodolite, perpendicular to the 

 line of vision. 41.4 metres south-east of the point of obser- 

 vation in the tent, Hence, the azimuth of Poldetind as 

 observed from the position of the theodolite on the islet. 

 was — 



48° 7/6 — 7/7 = N 47" 59/9 E 



From tin- southern extremity of the islet could be 

 seen another distant mountain-top. 10° 25' north of Polde- 

 tind. Sighted from the point of observation on the islet. 

 Husø signal was 182" 27' to the left of that summit. 

 The angle between Huso signal (bearing SW.) and Polde- 

 tind (bearing NE. i reckoned throngb the north, was accord- 

 ingly 192° 52''. The azimuth of Poldetind being N 48" 0' 

 E. that of Huso signal is —

Om Ettermiddagen opstilledes Instrumenterne paa 

 Skjæret paa en anden Plads. i Nærheden af den forrige. 

 Da Solen var synlig, benyttedes den til Azimutbestemmelse. 



In the afternoon the instruments were set up at a 

 point on the islet near to that previously selected. The 

 sun being visible', the azimuth was found from solar obser- 

 vations.
