The direction and velocity of the circulation are clearly shown in 

 considerable detail on the current map for the period, Figure 50, 

 page 90. 



The southernmost ice was the small berg previously mentioned in 

 the first part of our remarks, just south of the forty-fifth parallel on 

 the east side of the Bank. It was reported again and for the last 

 time on the 8th instant, reduced now to the size of the growler in 

 latitude 43° 54', longitude 48° 22'. It evidently had drifted off the 

 slope and been caught in the warm countercurrent which pressed 

 into the westward at this particular point. (See the ice map for 

 June, fig. 26.) Only four bergs succeeded in drifting south of the 

 forty-sixth parallel prior to the 8th instant and all but one of these 

 was deflected off to the eastward, south of Flemish Cap. 



On June 10, when just north of the forty-seventh parallel and 

 bound off the slope on a line of oceanographic stations, we sighted 12 

 icebergs scattered between the 50-fathom and 100-fathom curves. 

 The southerly current in this zone was calculated to be 0.3 to 0.2 

 knot per hour. (See fig. 50.) Two of the same bergs were sighted 

 again on the 11th, they having drifted southward to the forty-seventh 

 parallel and followed the general trend of the slope, a drift which 

 accords very closely with the current as calculated and drawn on the 

 current map. (See fig. 50, p. 90.) 



We were absent from the patrol grounds from the 13th to the 17th 

 instant, but upon our return at the latter date a total of five bergs 

 and several small pieces of ice were sighted in the vicinity of latitude 

 46° 00', longitude 47° 00', as shown on the ice map for the month. 

 (Fig. 26.) This was believed to be the same ice as that last seen by 

 the patrol on the 9th and 10th, then on the northern part of the bank. 

 These bergs were reported again by a steamer on the 21st near the 

 forty-fifth parallel and somewhat to the eastward, following a path 

 in general conformity to the stream lines of the current. Few bergs 

 were sighted on the northern tracks during this period, despite the 

 fact that it was clear weather in that locality. We kept a careful 

 record of the ships on the Cape Race tracks for a period of four days 

 and estimated there were a total of 15 bergs the latter part of the 

 month in this region. This would indicate that three-fourths of the 

 number sighted up to June 9, or 50 bergs, had melted during the 

 interim of two weeks, a sum which appears rather high. Probably 

 some of the missing number might be found upon further search 

 southward in the shoal water of the Bank, a locality which is seldom 

 crossed by passing vessels. 



We estimate there were a total of 95 bergs south of Newfoundland 

 during the month, or 27 more than the average. The bergs remained 

 concentrated on the northern part of the Banks, a condition which 

 was also noted during May. Only one berg drifted south of the
