200 REPORTS ON INVJiSTlGATIONS AND PROJECTS. 



Satisfactory progress has also been made in the land work. From the 

 details given later on it will be seen that the operations have been conducted 

 mainly in Peru and Brazil by Mr. Stewart ; in Asia Minor, Turkey, Arabia, 

 along the shore of the Red Sea, and Greece by Mr. Sligh; in Australia by 

 Messrs. Kidson and Webb ; and in China by Dr. Edmunds. Mr. Johnston, 

 en route to join the Carnegie at Cape Town, succeeded in securing magnetic 

 results at Freetown, Sierra Leone, and at two stations in the Canary Group. 

 The Director, on his way to meet the Carnegie at Colombo, Ceylon, made 

 magnetic observations at Tau Island, of the Samoan Group, on the day of 

 the total solar eclipse of April 28, 191 1 ; also at Pago Pago, Tutuila; Apia, 

 Samoa; and Colombo, Ceylon. Various opportunities have also been em- 

 braced to complete the intercomparison of our magnetic standards with those 

 of all foreign observatories. During the past year such comparisons were 

 secured at Vieques (Porto Rico), Pilar (Argentina), Cape Town, Apia 

 (Samoa), Port Louis (Mauritius), Batavia (Java), Alibag (Bombay), Dehra 

 Dun (India), Helwan (Egypt), Athens (Greece), Rome (Italy), Melbourne 

 (Australia), and Lu-kia-pang (China). 



During the Director's visit to Australian institutions, arrangements were 

 perfected towards the early accomplishment of the general magnetic survey 

 of Australia and outlying islands under the combined auspices of local and 

 governmental organizations, and of the Carnegie Institution of Washington. 

 Mr. Kidson was relieved at Colombo of ocean duty on the Carnegie and 

 placed in charge of the Department's work in Australia. He has been di- 

 rected to keep in touch with the local authorities and to render them every 

 assistance possible in the initiation and execution of magnetic work. The 

 Department has agreed to supply those in a position to cooperate effectively 

 with the required magnetic outfits in case they can not be immediately se- 

 cured otherwise. 



At Melbourne the Director met the committee having charge of the scien- 

 tific work of the Mawson Antarctic Expedition, and discussed with them the 

 proposed magnetic work in the Antarctic between Cape Adare and Gauss- 

 berg and embracing the region of the magnetic south pole. It was arranged 

 that the Department supply two outfits for magnetic-survey work, and 

 have Mr. Kidson give the necessary training to the observers. In order to 

 put this plan into immediate execution, as the expedition expects to leave 

 Melbourne in November of this year, Mr. E. N. Webb, associate in Engi- 

 neering, Canterbury College, Christchurch, New Zealand, was given a tem- 

 porary appointment as magnetic observer until November i, and assigned to 

 assist Mr. Kidson. Thereafter he will enter the employ of the expedition. 



From the statement under "Office work" it will be seen that the office 

 reductions have kept pace with the field work, and that the manuscript of 

 the first volume of "Magnetic Results," containing the results of the ocean 

 and land work to the end of 1910, will be ready to go to press next year. In 

 addition, several special investigations have been made, both with respect to
