her home port in the spring of 1917; the necessity of detaining her at 

 Buenos Aires, after declaration of war between Germany and the 

 United States, not only caused a delay of a year in her return, but also 

 prevented the completion of very important magnetic work in the 

 South Atlantic Ocean. 



Table 1 brings up to date the summary of the ocean magnetic work 

 of the Galilee and the Carnegie, 1905-1918. It will be seen from the 

 third column that the aggregate length of the three cruises of the 

 Galilee, 1905-1908, was 63,834 nautical miles and of the five cruises of 

 the Carnegie, 1909-1918, 189,176 nautical miles. The combined aggre- 

 gate length of the cruises of the Galilee and the Carnegie, 1905-1918, 

 is, accordingly, 253,010 nautical miles, or about 290,000 statute miles, 

 or about 113>^ times the Earth's circumference. All of these cruises 

 have been accomplished safely, with almost no mishaps and almost 

 no loss of life, but three sailors being lost through careless acts of their 

 own while off duty.

From plate 1 it will be seen that, except for certain regions, the 

 Pacific Ocean between 60° north and 60° south has been quite thorough- 

 ly traversed by the Galilee and the Carnegie, the tracks of these two 

 vessels, moreover, repeatedly intersecting. Instead of but a single
