DEPARTMENT OF TERRESTRIAL MAGNETISM. 297 



was crossed on December 9, so that date was repeated as December 

 9 (2). The vessel arrived at King Edward Cove, South Georgia, on 

 January 12, 1916, going the last 24 hours under her own auxiliary 

 power. The Carnegie again sailed on the 14th, being towed out of 

 harbor against a heavy head-wind by the steam whaler Fortuna. 

 Icebergs became more numerous, and fog was almost continuous. 

 However, January 18, 1916, was the only day on the entire trip in 

 southern waters on which it was impossible to obtain observations for 

 the magnetic declination. On January 22 the vessel passed along the 

 north coast of Lindsay Island, about 3 miles off shore. The Carnegie's 

 track of 1911 to the westward of Australia was twice intersected for 

 the determination of secular changes. Lyttelton was reached on 

 April 1, 1916. This sub- Antarctic passage was made practically 

 between the parallels of 50° and 60° south until Australia was ap- 

 proached, when it became necessary, on two occasions, to cross some- 

 what north of the fiftieth parallel, in order to secure the intersections 

 just mentioned. The total distance run from Lyttelton to Lyttelton 

 was 17,084 miles, giving an average of 145 miles for 118 days. The 

 entire track followed is shown in figure 2. 



The following extracts from the commander's reports on the circum- 

 navigation voyage are of interest : 



"For the first week after leaving Lyttelton the Avinds were mainly from 

 the SSW., forcing us considerably to the eastward of our route; so much so 

 that we sighted the Antipodes, bearing south, distant 20 miles, on December 

 9, and would have passed over the charted position of the Nimrod Group had 

 the wind remained in the south another 12 hours. It had not been the inten- 

 tion to go near this group, but the adverse winds sending us so near them, it 

 was decided to stand on toward the east another day, to endeavor to sight 

 them, but the wind shifted to the north 12 hours too soon and we passed 40 

 miles to the SW. of the position. [The Nimrod Islands were stated to have 

 been seen, at a considerable distance, by Capt. Henry Eilbech in the Nimrod 

 in 1828, who placed them in about 56|° S. and 158|° W.'] 



"On December 7, a mirage presenting the appearance of distinct and exten- 

 sive land was seen in the west, in the direction of Banks Peninsula, which was 

 190 miles distant at the time. 



"We crossed the one hundred and eightieth meridian December 9, so 

 repeated the date as December 9 (2). Our first piece of ice was sighted on 

 December 18, lat. 60° 12' S., long. 150° 46' W., and on December 19, 30 ice- 

 bergs, some being over 400 feet high and 1 mile long, were passed. We had 

 snow on December 18, 19, 20, and 21, and rather wintry weather. The 

 barometer dropped to 28.26 inches on December 18 during the snowstorm. 

 No icebergs were seen after December 24 until January 10, just before arrival 

 at South Georgia, when 8 or 10 good-sized bergs were passed. 



^According to Nature, vol. 97, No. 24.31, June 1, 1916, p. 2.37, "In 1909, on the homeward voyage 

 of the Nimrod, with Sir E. H. Shacklcton's Antarctic Expedition, Capt. J. K. Davis made a 

 thorough search for the Nimrod and Dougherty Islands, and failed to find them; they were in 

 consequence removed from the last edition of the Prince of Monaco's bathymetrical chart of the 

 oceans."
