43°2T' W., the soulliei-n limit latitude 41°23' N., and the western 

 limit, longitude 54^31' W. The southern limit, latitude 41^23' N., 

 was reached by only one berg. Exclusive of this berg, the southern 

 limit for June was latitude 44° 50' N. The above limits define an 

 extremely wide area over which the ice was distributed, but it must 

 be noted that these extreme boundary lines mark only the position 

 of an isolated berg or a scattered group of two or three bergs. At 

 the beginning of the month there was a considerable concentration 

 of the bergs north of latitude 46° N., and west of longitude 49° W., 

 but the number of bergs in even this ice-infected area dwindled so 

 rapidly that by the end of June the records show less than 25 known 

 bergs in the entire area south of latitude 49° N. It is estimated that 

 134 bergs drifted south of latitude 48° N. during June. The distri- 

 bution of ice for this month is graphically shown on the June Ice 

 Chart (fig. 8). 



JULY AND AUGUST 1935 



At the beginning of July, July 1 to July 7, only one iceberg threat- 

 ened the United States-European steamer lanes. On July 2, this 

 berg reached latitude 41°05' N., which marked the extreme southerly 

 position of ice for the entire season. The Ice Patrol vessel followed 

 this berg during its entire drift of about 425 miles, from June 18 

 until its final disintegration and disappearance on July T, in latitude 

 42°23', longitude 48°20' W. During this period this berg constituted 

 a constant menace to trans-Atlantic tracks B and C, during fog and 

 darkness. With the disappearance of this berg on July 7, the ice 

 menace in the North Atlantic ended for the season of 1935. 



The International Ice Patrol was discontinued on July 9, 1935, but 

 the United States Coast Guard cutter General Greene^ the oceano- 

 graphic vessel for the International Service of Ice Observation and 

 Ice Patrol in the North Atlantic, made an oceanographic cruise of 

 about 2 months duration in the regions of the supposed Newfound- 

 land Kidge northeast of Flemish Cap and the Labrador Deep be- 

 tween Cape Farewell, Greenland, and the Grand Banks. During 

 this period, July 9 to September 1, ice conditions in the North Atlantic 

 were learned as far as possible from the reports of passing vessels 

 and, of course, the General Greetie's, own observation. The only re- 

 port of field ice for this period came on July 17. Scattered patches 

 of field ice were reported from latitude 53° W. to Belle Isle. No 

 bergs drifted south of latitude 46° N., and only 14 bergs were reported 

 south of latitude 48° N. On August 9 a growler, or very small berg, 

 was reported at the southern tip of the Grand Banks in latitude 

 43°07'' N., longitude 50°09' W. The apparent concentration of bergs 

 in the Straits of Belle Isle and to the eastward along the steamer 

 tracks is due, of course, to the manj^ reports in this much traveled
