At the first winter-quarters station an observatory was built for the mag- 

 netometer and dip-circles, and a connected building for the photographic 

 declinometer. Observations were made here from October 1918 until August 

 1919. Magnetometer and dip-circle results here total 181 values of declina- 

 tion, 121 of inclination, and 227 of horizontal intensity. Sixteen additional 

 stations were established on sledge trips in the surrounding region, comprising 

 the Chelyuskin Peninsula and extending northward to Crown Prince Alexei 

 Islands. 



When the Maud succeeded in getting away from her first winter quarters, 

 two members of the crew were left behind, with all the original records of the 

 first winter's observations, which they were to carry by sledge to Port Dickson. 

 It now appears that these men unfortunately have been lost. The absolute 

 results of this winter's work have been computed from copies kept on board 

 the Maud, but there were no copies of the photographic registrations. 



During the second winter the magnetic instruments were mostly used on the 

 sledge trips. In addition to the winter-quarters station, 19 others were occu- 

 pied, the most distant one being 700 miles away at Bering Strait. Again, the 

 third winter, nearly all the magnetic observations were made on sledge trips. 

 On one trip lasting 69 days, 1,200 miles were covered and 11 magnetic stations 

 occupied. 



In all, 53 stations appear in the condensed table of results. Nos. 22 and 42 

 are identical, while in several instances stations are very near each other. 

 Examples of close stations are Nos. 21 and 40 and Nos. 34 and 38. On the 

 Chelyuskin Peninsula, also, the stations are rather close together in some cases. 



At 19 of the 53 stations, declination, inclination, and horizontal intensity 

 were measured. At 32 of the other 34 stations only the two elements, inclina- 

 tion and horizontal intensity, were observed, while at two stations there was 

 only inclination. 



Values of the magnetic elements in the table of results are based on inter- 

 national magnetic standards. This has been secured in a satisfactory manner 

 by means of comparison observations with the standards of the Department 

 of Terrestrial Magnetism both before the expedition and after the return, as 

 well as by intercomparisons by the observers in the field. 



The magnetic results of the expedition, compared with those of Norden- 

 skiold for 1878 and 1879 and of Nansen for 1893, furnish valuable secular- 

 variation data for the Siberian coast. 



Meteorology on Captain Amundsen's present Arctic Expedition. H. U. Sverdrup. 

 Monthly Weath. Rev., vol. 50, 74-75 (February 1922). 



This paper gives a brief account of the meteorological observations taken 

 during the three years 1918 to 1921, spent on the north coast of Siberia, and 

 a brief outline of the plans for the meteorological work on the contemplated 

 drift of the expedition's vessel, the Maud, beginning in 1922, across the 

 Arctic Sea. During the drift, barometric pressure, temperature, humidity 

 and wind are to be registered continuously, and the registrations are to be 

 checked by three daily observations. Investigation of the upper air-currents 

 by means of pilot balloons and kites is to be made. Meteorological observa- 

 tions are also to be made on the airplanes used for geographical exploration. 

 Daily weather reports are to be forwarded from the vessel by wireless, it 

 being hoped to keep in communication with Nome during the first part of the 

 drift and with Spitzbergen during the last part.
