167 43' and the usual winter observations were carried out. In July 1920 the party 

 arrived at Nome, Alaska, and after a brief visit set out for the north again to begin the 

 drift across the polar seas. 



J. P. Ault. In October 1917 Mr. J. P. Ault reoccupied the United States Coast and 

 Geodetic Survey station at New London, Connecticut, and established 5 additional 

 stations in the immediate vicinity for the purpose of controlling compass-variometer 

 observations made on the waters around New London in connection with experiments 

 made to improve the form of that instrument for marine use. 



L. A. Bauer. At the conclusion of special observations at the time of the eclipse 

 of June 8, 1918, the Director, Dr. L. A. Bauer, proceeded to Manitou, Colorado, where 

 he personally supervised the work of making a detailed magnetic survey of the region 

 about Pikes Peak. He was assisted by Messrs. W. J. Peters, H. W. Fisk, and C. C. Ennis, 

 who made observations at 24 points in the vicinity, including 3 stations on the summit 

 of the mountain. Additional stations were occupied at about the same time by observers 

 of the United States Coast and Geodetic Survey. The stations were selected at different 

 altitudes, ranging from about 6,000 feet at Colorado Springs to over 14,000 feet on the 

 summit of Pikes Peak, distributed around the mountain at such points as were available 

 for the purpose; views 2 and 3 of Plate 5 are typical of these stations. During the time 

 this work was in progress, the magnetograph instruments set up at Lakin, Kansas, for 

 the eclipse work were kept in operation in charge of Mr. D. M. Wise. 



On the total solar eclipse expedition of 1919 to Cape Palmas, Liberia, Dr. L. A. 

 Bauer, in company with Mr. H. F. Johnston, determined the magnetic elements at the 

 eclipse station and at points in the immediate vicinity. The details of this expedition 

 are given in the special report on the eclipse observations of May 29, 1919. 



F. Brown. Mr. Brown concluded his trip across Africa from Benguela to ports on
