light blue sky to as great a distance as the curvature of the earth will 

 allow them to be seen, usually from 15 to 20 miles for a masthead 

 lookout. Speed had to be limited to 70 revolutions per minute, 

 which gave between 9 and 10 knots, because of the continuing neces- 

 sity for carefulh^ regulating fuel consumption. A rectangular area 

 to the northeastward was covered during the da}'- and most of the ice 

 reported by the M. Christensen w^as checked as to position and drift. 

 The latter was found to be about 1 knot in a southwest direction. 



Two new bergs were found just south of 46° N. and just east of the 

 forty-eighth meridian. The berg left early in the morning was 

 reached again before dark and was watched during the night. It 

 drifted first to the southeast and then to the east, evidently having 

 been checked in its southwesterly course by some such shoulder of the 

 Gulf Stream as often presses in close to the Bank a little north of the 

 Tail, so cutting off the flow of the Labrador current. Reports of 

 relatively high temperatures from passing vessels gave further 

 evidence of the existence of such a shoulder of warm surface water at 

 the time. 



Ice scouting was continued on the 31st, for the winds were as light 

 and the visibility was about as good as on the preceding day. By 

 noon it began clouding over, due to the approach of another *'low" 

 from the west. By 3.30 p. m. the weather was thick and rainy so 

 the searching was abandoned. During the good visibility a consider- 

 able area to the westward to the 50-fathoni curve had been covered 

 and one more unreported berg had been located. A check up was 

 also had on the westernmost berg reported by the M. Christensen on 

 the 29th, which proved to have drifted due south at about 0.5 knot. 



The night of the 31st the Mojave spent near the newest berg, which 

 was believed to be the southernmost ice. During the night it was 

 lost in the storm and fog, but the next morning was found by steaming 

 about 10 miles to windward. 



The 1st of April was spent near this berg in order to follow its 

 drift. It was the largest berg seen so far during the season, measuring 

 about 200 feet square and averaging about 30 feet high above the 

 water line. All the bergs sighted so far had been rounded and water 

 glazed except where sharp cliffs were in evidence — in some places 

 about the sides, w^iere overhanging projections of ice had calved off. 



At 4 a. m. on the 2d the patrol vessel stood to the southward to 

 take a line of stations from a point in the warm current in toward the 

 Bank. Seven stations were taken down to the 750 meter level during 

 the day between the forty-eighth and forty-ninth meridians in latitude 

 44° 27' N. They showed a gradual cooling of the surface water 

 from 7° to —1.1° C. as the Bank was approached. A calculation of 

 these stations determined the comparatively narrow width of the 

 south-flowing stream and its appro::imate speed at the time and place.
