326 CARNEGIE INSTITUTION OF WASHINGTON. 



During the winter of 1920-1921, observations were made at the winter 

 quarters of the Maud at north latitude 66° 53' and west longitude 171° 

 39' on Chukchen Peninsula in eastern Siberia. A sledge journey 

 was undertaken in February to April around the coast south and west 

 as far as Holy Cross Bay, and inclination and intensity observations 

 with a Dover dip circle were made at 11 stations; approximate declina- 

 tions were also secured when conditions were favorable. An attempt 

 on the return to cross the peninsula from the Gulf of Anadyr on the 

 south to Kolyuchin Bay on the north was unsuccessful on account of 

 the deep snow. In April, observations were made at Pitlekai, where 

 Nordenskjold wintered in 1878-1879. The suspension of the work of 

 the expedition in order to permit necessary alterations and repairs to 

 be made to the vessel allowed an opportunity for Dr. H. U. Sverdrup, 

 who with Mr. O. Wisting had made a great part of the magnetic obser- 

 vations, to come to Washington. He arrived on October 25 with the 

 magnetic instruments, which he will compare with the standards of 

 the Department. 



On his journey from the eastern coast of Africa to Watheroo, Western 

 Australia, Observer F. Brown visited the Department's secular-varia- 

 tion station at Aden, Arabia, making observations there early in Sep- 

 tember, and later in the month at the Admiralty station of 1909 

 situated across the harbor. Leaving Aden on September 26, he pro- 

 ceeded to Colombo, Ceylon, where the station at that point was again 

 reoccupied. 



AUSTRALIA. 



Absolute observations, as well as continuous photographic registra- 

 tions, have been made throughout the year at the Watheroo Magnetic 

 Observatory (see page 328). On October 23 Observer Brown arrived 

 at Watheroo after the completion of his work in Africa and compared 

 his instruments with the observatory standards. At the end of the 

 month he was engaged with Assistant Observer J. Shearer in reoccupy- 

 ing a few of the Department's stations in Western Australia. Obser- 

 ver D. G. Coleman arrived at Sydney from Fiji Islands on October 14, 

 and reoccupied the stations at Red Hill and East Maitland. 



ISLANDS, PACIFIC OCEAN. 



Mr. Coleman, as a member of Dr. H. M. W. Edmonds's party, after 

 the completion of the Carnegie's observations at Apia. Samoan Islands, 

 in July 1921, began the reoccupation of a series of stations occupied in 

 1906 and 1915 among the islands of the South Pacific Ocean, and by 

 the middle of October had occupied 9 stations in the Ellice, 3 in the 

 Tokelau, 2 in the Tonga, and 2 in the Fiji islands. From Fiji he went 

 to Sydney, Australia, to arrange for further work among the Solomon 

 Islands. 



The Carnegie made observations at Christchurch, New Zealand, in 

 the latter part of October and early November at two of the stations
