wished to sight. The course was accordingly changed for this new 

 position and at the same time radiocompass bearings were taken of 

 the Stadsdijlc. While we were maneuvering to get in touch with 

 this ice a message was received from the steamship George Wash- 

 ington that she had just passed a small berg about 35 miles to the 

 eastward of where we were then and on the westbound steamer track. 

 We immediately headed that way, made contact with the Washington 

 at 11 o'clock, and picked up the berg just before sunset. 



The Tampa remained close to this berg during the next four days, 

 as long as it continued to be a menace to navigation. During the night- 

 time it was our practice upon the approach of steamers to throw^ the 

 searchlight beam on the ice clearly marking its position. That this 

 was appreciated is shown by the following message from the steam- 

 ship Mauretania, which passed close to the Tampa one night. "We 

 are passing south of you; can see berg in your searchlight beam. 

 Thank you. Rostron." 



A dispatch on June 2 broadcasted from Arlington radio station 

 stated that the trans- Atlantic track conference had decided to change 

 from tracks B to tracks A immediately, the eastbound track being 

 moved June 2 to 39° 30' latitude, and the westbound track being 

 moved simultaneously to latitude 41°, with the complete shift of 

 the westbound to latitude 40° 30' on the 9th instant. 



On June 4, wdth the melting of the aforementioned berg, the patrol 

 vessel shifted its position 4 miles to the northward near a large berg 

 which had been sighted the previous day. A survey was made of 

 the exposed surface above water; a tower, the highest point on one 

 end, measured 55 feet; the opposite end, 35 feet; and the length 

 was 382 feet. It is worth mentioning here that the heights of bergs 

 can be measured quite accurately by climbing the mast to a point 

 where the line of sight of the observer passes tangent to the summit 

 of the ice and through the horizon. A correction of 4 feet should be 

 added to this as the correction for the dip of the horizon. Measured 

 heights from the water line can be easily marked upon the mast in 

 units of 5 feet, and it will seldom be found that heights of bergs will 

 exceed the height of the crow's nest. 



While the Tampa was lying alongside of this ice on June 5 the 

 steamer Leviathan passed close aboard about 9 o'clock in the morning. 

 She thanked the patrol for its services and very complimentary 

 added, "Your vigilance was an inspiring sight to everybody on board. 

 Hartley." Captain Fisher replied, "Glad to be of service to the 

 queen of the American merchant marine. Your passing ship was 

 an inspiring and beautiful sight." The early jnorning hours of 

 June 6 witnessed the complete melting of this ice. 



The last few days of the Tampa's cruise were spent patrolling along 

 the southern boundary of the fog wall as it was impossible to carry 

 on any ice scouting in the cold waters to the north w{iiPdt;";Th©-^
