fog, stopped approximately 1 mile to leeward of berg and drifted. 

 The chip log showed that the vessel drifted 1.25 miles per hour approxi- 

 mately north, true, under the influence of the wind alone. Light to 

 fresh breezes, SE. to S., with cloudy weather and very thick fog the 

 latter part of the day prevailed. 



April 14 began with a dense fog, which lasted until dayhght. At 

 6.15 a. m. set course 200°, true, and stood back to the berg, alongside 

 of which we hove to yesterday. The Tampa lay to during the day 

 and drifted, keeping the berg in sight. It was found that this berg 

 was drifting north at the rate of 0.3 knot per hour. (See chart '' D.") 

 The wind was moderate to light from WNW. to SE., and the weather 

 was partly cloudy, with dense fog at the beginning of the day. 



April 15 began with our drifting near the southernmost berg, 

 which was now melting rapidly. During the afternoon steamed back 

 to the berg, from which we had drifted 7 miles in 10 hours. Light 

 to moderate N. to W. winds, partly cloudy weather, and smooth sea 

 to moderate swell prevailed during the day. At 8 p. m. the steamship 

 Cantigny reported a small berg in lat. 42° 02' N., long. 50° 42' W. 



At midnight, the beginning of April 16, stood to the westward in 

 search of the small berg reported by the steamship Cantigny. At 

 9 a. m. passed a growler in lat. 42° 03' N.,long. 50° 36' W., which 

 was eviaently the berg reported by the Cantigny. At 9.30 a. m. set 

 course 281°, true, to intercept the Seneca. At 11 a. m. passed a 

 small growler in lat. 42° 06' N., long. 51° 02' W. At 2.30 p. m. we 

 were relieved by the Seneca, in lat. 42° 12' N., long. 51° 55' W., and 

 the oceanographer and scientific observer were transferred to that 

 vessel. Light to moderate NE. breezes and mostly cloudy weather 

 were experienced during the day. 



During this cruise of the Tampa we received approximately 460 

 sea-water temperature reports, positions, and courses from vessels 

 in the ice areas between longs. 43° W. and 55° W. Daily broadcast 

 warnings were sent by radio to all vessels, and daily ice reports were 

 sent to the Hydrographic Office, New York, and, beginning April 8, 

 also to Fuelite, Halifax, Nova Scotia. Vessels were, for the most 

 part, warned to keep south of lat. 42° N. between longs. 49° W. and 

 52° W. 



The following steamsliips were given special ice warnings on the 

 dates specified: April 2, Dighy and Northwestern Miller; April 3, 

 Cassandra and West Samoset; April 4, Ahsaroka, La B or donna, and 

 America; April 6, Baltic and Lucerna; April 7, Sachem, Wells City, 

 Lucerna, and Tiger; April 8, Sachem; April 9, Suisinawa and YJM; 

 April 12, Finland and Lexington; April 13, Lexington, Cedric, and 

 Cythia; April 14, La Touraine and a vessel whose name was not 

 obtained. 



On April 11 the following broadcast was sent out: "Ice patrol 

 Tampa, 42 N., 50 W. Bergs and growlers along east side Great 

 Bank extending southward. All vessels advised keep south of 42 

 between 49th and 52d meridians. Report positions, courses, water 

 temperatures often." 



On April 15 the following broadcast was sent: "42 30, 49 17, 

 drifting near small berg 0.2 knot per hour northerly. Small berg 

 reported 42 02, 50 42. Warning all vessels south of this position 

 between 49th and 52d meridians.
