SCIENCE. 



[N. S. Vol. XVIII. No. 454. 



Carolina and the eastern portions of Ken- 

 tucky and Tennessee, will be completed and 

 the results at once submitted to a careful dis- 

 cussion, with the view of ascertaining what 

 improvements, if any, are needed in the 

 methods of work, to bring out all of the prac- 

 tical and scientific purposes of a magnetic 

 survey. 



The work in Louisiana was done in coopera- 

 tion with the State Geological Survey. 



B. Ocean Survey Worh. — In January, 

 1903, a Lloyd-Creek dip circle was mounted 

 on the Coast and Geodetic Survey Steamer 

 Blake and observations made on the trip to 

 Porto Eico and return. Some compass work 

 has also been done by the other vessels of the 

 survey. The work has largely been of an ex- 

 perimental nature as yet. It has been demon- 

 strated, however, that if the proper precau- 

 tions are taken, valuable results may be se- 

 cured. The Lloyd-Creek dip circle has been 

 proved to be a most satisfactory instrument 

 for both land and sea work. 



G. Magnetic Observatory WorJc. — The four 

 magnetic observatories situated at Cheltenham 

 (Maryland), Baldwin (Kansas), Sitka 

 (Alaska) and near Honolulu (Hawaiian Is- 

 lands) have been in continuous operation 

 throughout the year. Owing to various im- 

 provements being made in the vertical-force 

 instrument, only the first-named observatory 

 is provided with such an instrument, and, in 

 fact, at this observatory a double set of photo- 

 graphic instruments are in operation (Adie 

 pattern and Eschenhagen pattern). 



In February, 190-'^, a temporary magnetic 

 observatory was established in Fort Isabel, 

 Bieques Island, Porto Rico, and since March 

 registrations of declination and horizontal in- 

 tensity have been secured. 



D. Special Investigations. — A variety of 

 special investigations have been made, em- 

 bracing experimental work in the field and at 

 the observatories and theoretical investigations 

 at the ofiice. Thus, for example, a prelimi- 

 nary examination was made of the locally dis- 

 turbed region in the vicinity of Machinac 

 straits, some magnetic observations having 

 been made on the ice during the past winter, 

 in addition to some shore observations. 



E. Expeditions. — Besides the work of the 

 survey proper, two expeditions have been 

 fitted out with magnetic instruments and the 

 observers given the necessary training and 

 furnished with the requisite data and instruc- 

 tions ; viz., the Zeigler North Polar Expedi- 

 tion, W. J. Peters being in charge of the mag- 

 netic work and the Bahama Expedition of 

 the Baltimore Geographic Society, 0. L. 

 Fassig being in charge of the magnetic work.
