DEPARTMENT OF TERRESTRIAL MAGNETISM. 301 



The preliminary equations already deduced in the consideration of 

 tilting deviations were confirmed by Dr. Slocum and found to accord 

 with those of Starling. Dr. Slocum found that the subject had already 

 been discussed by Lord Kelvin (Math, and Phys. Papers, Vol. IV, 

 pp. 464-469) to some extent, but for compasses only. 



Since December 1, 1919, the highly important duties involved in 

 the first auditing of the miscellaneous monthly disbursements by the 

 various divisions and expeditions of the Department and in preparing 

 the requisite financial statements and inventories for the Institution 

 have been intrusted to Mr. M. B. Smith, as chief clerk and cashier. 

 Since 1908 these duties had been faithfully performed by Mr. J. H. 

 Millsaps, who resigned in order to accept a position of responsibility 

 in Chicago. 



A large part of the time of the Administrative Division is given to the 

 routine work of accounts, miscellaneous correspondence and type- 

 writing, filing of photographs, and miscellaneous checking. Until 

 June the progress maps were plotted by Mr. Smith, with Mr. Ennis's 

 assistance in ocean plotting. Subsequently, this work was all turned 

 over to Mr. Ennis. In the revision of field cahiers Mr. Duvall has 

 worked under the supervision of the Magnetic Survey Division. The 

 Table of Magnetic Results and descriptions of stations for Volume IV 

 were prepared in part by Miss Tibbetts with the help and advice of 

 the Magnetic Survey Division. 



The personnel of the division during the year has been as follows: 

 W. J. Peters, chief; C. R. Duvall, expert computer; J. H. Millsaps, 

 bookkeeper-cashier, resigned December 31, 1919; M. B. Smith, 

 advanced from property clerk in the Magnetic Survey Division to 

 position of bookkeeper-cashier December 1, 1919, and to position of 

 chief clerk December 18, 1919; H. D. Harradon, to December 1, 1919, 

 librarian-translator, on which date he was transferred to the Division 

 of Research in Terrestrial Magnetism; Miss Elsie E. Johnson, assistant 

 librarian and typewriter, resigned November 30, 1919; Miss Emma L. 

 Tibbetts, transferred from the Division of Research in Terrestrial 

 Magnetism to the Administrative Division as stenographer-computer, 

 November 26, 1919; A. J. S. Dixon was transferred from the position 

 of day watchman in the Magnetic Survey Division to that of mes- 

 senger, under the direction of the chief clerk. 



MAGNETIC SURVEY DIVISION. 



Mr. J. A. Fleming has continued as chief of the Division, with 

 Messrs. H. W. Fisk and J. P. Ault as chiefs respectively of the Sections 

 of Land Work and of Ocean Work. During December 28, 1919, to 

 April 17, 1920, Mr. Fleming was in the field on inspection work. 

 Captain Ault has been on field duty in command of the Carnegie 

 throughout the year.
