bergs which had been lost in the fog were thought to have drifted 

 either up on the southwest slope of the Bank or to the northeast in 

 the counterset. In any event the current map showed that there 

 was very little likelihood to suppose that the ice had been transported 

 southward in the fog toward the steamship lanes. 



Late in the afternoon of the 20th the steamer Tiger sighted 20 

 bergs off the Tail about 30 miles and so during the night we shaped 

 a course so as to be in an advantageous position to commence search- 

 ing at daylight on the 21st. During the next two or three days 

 the patrol searched this entire area and plotted the positions of a 

 total of 20 bergs and three growlers. As this discussion with sketches 

 is taken up on page 65, it will not be entered upon here. On the 

 23d it was observed that the bergs farthest offshore to the southeast 

 were slowly being turned in the current and were beginning a counter 

 drift to the northeast. Later in the morning the Modoc laid a course 

 to the southward and westward because no chances wished to be 

 taken on bergs drifting unawares in that dangerous direction. While 

 we were steaming in this quarter a fog bank rolled in completely 

 enveloping the ice infested waters. 



The approach of the Tampa returning for a new tour of duty was 

 announced by radio the night of the 23d and so we headed over to 

 the westward, meeting at a rendezvous about 100 miles west of the 

 Tail. The Modoc received 67 reports of ice sighted by passing 

 vessels, furnished ice information to 10 ships, requested acknowl- 

 edgment from 22 vessels for the regular ice broadcast, and received 

 775 surface temperature reports during the cruise thus terminated. 



THE FIFTH CRUISE, "TAMPA," MAY 25 TO JUNE 10, 1926 



After relieving the Modoc the Tampa stood eastward toward the 

 group of bergs last seen by the Modoc on the 23d instant but fog 

 shut in the morning of the 26th causing us to drift until the arrival 

 of clear weather again. Sometime during the morning we received 

 a radio from the steamer Clearpool reporting a berg and growler in 

 latitude 41° 49', longitude 50° 12'. We immediately requested the 

 master of the Clearpool to verify his position and indicate how recently 

 he had obtained astronomical sights, because this position was con- 

 sidered surprisingly far south for any berg to drift so quickly. The 

 reply stated that the previous position was in error and gave the 

 latitude as 42° 24'. The Tampa got under wa}^ and had not pro- 

 ceeded very far when a growler was sighted close aboard in the fog. 

 This we thought might be the same growler that the Clearpool had 

 seen earlier in the day, so taking it as a point of departure we headed 

 eastward about 10 miles where a berg was found. When the fog 

 cleared later on we beheld five bergs in sight to the eastward, and 

 so we steamed over to the largest one. This group of bergs was
