308 CARNEGIE INSTITUTION OF WASHINGTON. 



Dr. W. F. G. Swann, assisted by Dr. C. W. Hewlett and Observer 

 Johnston, made the final installations for the atmospheric-electric 

 work and prepared the necessary directions. 



When the Director had made his inspection of the vessel and had 

 given the final instructions regarding the cruise and the program of 

 work, the Carnegie left Brooklyn, on June 8, direct for Hammerfest, 

 Norway, with the following personnel aboard : J. P. Ault, magnetician 

 and in command of vessel; Dr. H. M. W. Edmonds, magnetician and 

 surgeon; Observers H. F. Johnston and I. A. Luke; N. Meisenhelter, 

 meteorological observer and clerk; R. E. Storm, mechanical engineer; 

 Watch Officers J. Sahlberg, J. Johnson, and T. Pedersen; Mechanic 

 C. Heckendorn; 8 seamen, 2 cooks, and 2 cabin boys; 22 persons in all. 

 Mr. Martin Clausen, who had served faithfully, first as second and 

 later as first w^atch officer on the previous cruises, on May 17, during 

 shore leave, unfortunately met with an accident and died on May 24. 

 On May 27 Mr. John Sahlberg was appointed first watch officer in his 

 stead. 



The Carnegie followed a course from Brooklyn practically due east 

 along the parallel of 41° north to about 53° w^est longitude, and thence 

 practically in a direct line to Hammerfest. A landfall was made in 

 the vicinity of the Faeroes on June 27. Hammerfest w^as reached on 

 July 3, after a cruise of 4,182 nautical miles. In addition to the usual 

 stations occupied at Hammerfest for the purpose of determining the 

 instrumental constants, observations were secured in the neighborhood 

 at five additional stations for the purpose of selecting a suitable place 

 in the harbor to ''swing" the vessel, and thus test anew the absence of 

 ship deviations at the mounts of the magnetic instruments. " Swings " 

 were secured on July 15, 16, and 18, with satisfactory results for both 

 horizontal intensity and inclination, as also for declination, due account 

 being taken of the small horizontal intensity (0.1 c. g. s.) at this high 

 magnetic latitude. These tests showed once more, as in the previous 

 cruises, that there are no deviations of sufficient magnitude to be taken 

 into account. On July 25 the Carnegie left Hammerfest, bound this 

 time for Reykjavik, Iceland, Captain Ault's instructions being to pro- 

 ceed as far north as ice-conditions permitted, without endangering the 

 safety of the vessel. 



The following interesting extract is taken from Captain Ault's 

 report, dated Reykjavik, AugTist 27, 1914: 



"After leaving Hammerfest it was planned to make a short trip into the 

 Barents Sea towards Nova Zembla, but, head winds being encountered, the 

 course was shaped for Spitzbergen. We were becalmed 2 days off Bear Island, 

 after which we had fair winds until July 31, when Ave sighted ice about 30 

 miles south of South Cape, the southernmost point of Spitzbergen. A few 

 hours later we were headed off by the solid ice-pack, but we could see the 

 western edge of the pack and knew that by standing to the westward we could
