lished for the Department by Professor Luigi Palazzo, he made various 

 inquiries and preparations for a trans-Saharan expedition from Tripoli 

 to Lake Chad. At the end of December he left Tripoli for an expedi- 

 tion along the northern coast of Tripolitana, during which he observed 

 at eight stations, his most eastern station being Tobruk. Thence he 

 proceeded to Alexandria, and, after securing observations there, he 

 obtained intercomparisons between his instruments and those of the 

 Helwan Observatorj-. On the return to Alexandria, he carried out a 

 caravan trip to k:ellum, Egypt, observing at 8 stations. Leaving 

 Alexandria on May 16, he reoccupied our previous stations at vSuez 

 and Aden, Arabia. From Aden the journey was continued to the 

 French Somali coast, observations being made at Jibuti and thence at 

 8 stations en route to Adis Abeba, Abyssinia, where he arrived on 

 July 8. From Adis Abeba he carried out a caravan trip northward to 

 Massaua, on the Red Sea, where he arrived early in October. He then 

 returned to Tripoli. 



ASIA. 



The magnetic work in Asia during the year had to be confined to that 

 of Dr. C. K. Edmunds. During April and Mslj he constructed on the 

 campus of the Canton Christian College, at Honglok, near Canton, 

 two non-magnetic huts to serve for comparisons and standardizations 

 of magnetic outfits. During July and August he made two short 

 excursions from Canton, securing observations at about 8 stations, 

 one of w^hich was the secular-variation station at Macao, China. It 

 was not found possible to undertake more extensive work in China 

 during this year. Dr. Edmunds was accompanied on his trips by a 

 Chinese assistant, Mr. H. Suen. 



AUSTRALASIA. 



The general magnetic survey of Australasia, under the charge of 

 Observer E. Kidson, has been practically completed during the present 

 year. During November 1913, Mr. Kidson was still at work in 

 Queensland, observing at points along the east coast as far north as 

 Townsville and on the railway line between the coast and the western 

 part of the state. He returned to Brisbane the latter part of November. 

 His assistant. Observer F. Brown, after the conclusion of a successful 

 trip by automobile, was at work in Northern Queensland, especially 

 in Cape York Peninsula, beginning at the secular-variation station on 

 Thursday Island and ending at the secular-variation station. Cook- 

 town. Thence he proceeded to Hobart, Tasmania, arriving there 

 January 6. 



From the end of December to January 21, Mr. Kidson continued the 

 magnetic-survey work in Tasmania and King Island, where he occupied 

 10 stations, including a number of stations that had been previously 

 occupied in the course of the Tasmanian Magnetic Survey. He arrived 

 at Melbourne on January 23. After a month's leave of absence he
