Observers' Field Reports

Washington. Comparisons were obtained with Kew, Greenwich, Stonyhurst, and 

 Eskdalemuir observatories in August, September, and October 1915, war conditions pre- 

 venting an inclusion of other European observatories in the series. The results of these 

 observations are fully discussed in the special report on observatory comparisons. 



W. J. Peters and D. W. Berky. During an expedition in the summer of 1914 in the 

 three-masted schooner George B. duett (see view 7 of Plate 5) to Hudson Bay and adja- 

 cent waters, land observations were made at Battle Harbor and points in vicinity and, 

 as opportunity offered, at landings during the cruise. Reconnaissance observations were 

 made also at points about the Battle Harbor station to determine the desirability of 

 that place as a location for a magnetic observatory. The expedition left Boston on June 

 21, 1914, sailed from Battle Harbor for the north on July 30, and returned late in October. 

 Stations were occupied at Bay of Islands, Newfoundland, and at Sydney, Nova Scotia, 

 on the return to Washington, where the party arrived on November 14. The land stations 

 occupied were as follows :

i Eleven supplementary stations were established here to test for local disturbance. 



The results obtained by observations on board the schooner during the cruise will 

 be published in a subsequent volume of these Researches. 



A. D. Power and L. L. Tanguy. The Carnegie was detained in port at Buenos Aires 

 from March 2 to December 4, 1917, because of conditions arising from the Great War. 

 An opportunity was thus afforded for sending out members of the party to reoccupy 

 magnetic stations of the Meteorological Service of Argentina for secular-variation data. 

 Accordingly, Messrs. A. D. Power and L. L. Tanguy were assigned to this work by Cap- 

 tain Ault, and several series of expeditions were planned so as to cover all portions of the 

 country that could be reached from the railroads. During the early part of the work 

 Messrs. Power and Tanguy traveled together, but, as Mr. Power's services were required 

 aboard the Carnegie after July 1, Mr. Tanguy completed the program alone. The Argen- 

 tine government not only took a kindly interest in the work but also rendered material 

 assistance, providing free transportation over the railway lines and on the government 

 steamers. Magnetometer-inductor No. 25 was used; it was compared before and after 

 the field work with the standards at the Pilar Observatory.
