inclusive. Warnings were broadcast at 6 a ni. and at 6 p. m., 75th 

 meridian time, from the night of the 11th to the night of the 19th, 

 inclusive. As the vessel never anchored, no current observations 

 were made and what drift was observed could be accounted for by 

 wind surface set. The prevailing winds were strong SW. to NW., 

 with choppy sea. The following steamers gave us ice reports: 

 Wei/ingham, Lord Dvfferin, Canadian Mariner, Gallymere, Cottage 

 City, and Pinemoor. vSixty-eight vessels contributed 321 surface- 

 water temperature reports, according to which the edge of the Gulf 

 Stream swept in an easy curve through lat. 42° 00' N., long. 55° 

 00' W.. lat. 41° 30' N.,"^long. 50° 00' W., lat. 42° 30' N., long. 46° 

 00' W. 



The Tampa was intercepted in lat. 42° 50' N., long. 50° 45' W. 

 at 5 p. m., March 19, when the patrol was taken over by that vessel.

The Tampa left Boston Navy Yard at 1 p. m., March 15, to relieve 

 the Seneca on international ice patrol duty. Light airs to gentle 

 loreezes were experienced until the early morning of March 16, 

 when the southerly breeze gradually increased to moderate and fresh 

 gale, S, to SW., with falling barometer, which continued from 10 

 a. m. the 16th until 4 a. m. the 17th. This was followed by a rising 

 barometer, the wind shifting to NW. and falling to gentle and light 

 variable breezes, which continued until the night of the 19th. The 

 southerly gale made up a very heavy sea on the night of the 16th 

 and 17th. Flying fish were observed in the forenoon of the 19th, 

 in lat. 42° 50', indicating that the Gulf Stream was unusually far 

 north. At 12.20 p. m., March 19, a berg, apparently of medium 

 size, was sighted in lat. 43° 00', long. 51° 48'. At 3.30 p. m. the 

 same day a second medium-sized berg was sighted, in lat. 42° 58', 

 long. 50° 52'. The Tampa met the Seneca at 4.40 p. m., March 19, 

 in lat. 42° 49', long. 50° 39'. and relieved her of the ice patrol duty, 

 the Seneca leaving for New York. At 6.05 p. m. the Tampa stood 

 65°, true, for a third berg, sighted some 8 miles distant, and at 

 6.50 p. m. stopped and drifted for the night in the vicinity of the 

 berg. As per arrangement, the routine reports were sent out by 

 the Seneca this day. 



March 20 began with the vessel drifting. At 5.30 under way to 

 locate the last berg sighted on the previous day. At 7.05 a. m. 

 sighted the berg, distant 6 miles. Stood around berg, photographed 

 it, and ascertained that it was grounded on the Tail of the Bank in 

 lat. 42° 55', long. 50° 21'. Many shearwater, dovekies, and a few 

 sea parrots were in the vicinity of this berg. The following weather
