On the morning of April 11, the grounded berg was ascertained to be 

 in the same position and at noon the Mendota steamed to the north- 

 eastward to contact the General Greene, which was met at 1415, and 

 a current map of the critical area was delivered by heaving line over 

 the stern of the Mendota. The General Greene proceeded to St. John's, 

 Newfoundland. Three average sized bergs were found this day in the 

 following positions: latitude 44°46' N., longitude 48°43' W., latitude 

 44042' N.^ longitude 48°51' W., and latitude 44°37' N., longitude 

 48°43' W. These bergs were in the south bound current as shown 

 by the current chart and moved rapidly southward accordingly. 

 Following the southward drift of this ice occupied the remainder of the 

 patrol. During the day of April 12, the area between latitudes 43° 

 N., and 44° N., in the cold current was searched in an effort to locate 

 the two small bergs and two growlers last sighted just north of latitude 

 44° N., on April 9. This ice was not found nor was any other ice 

 sighted in this area. Northeast winds and poor visibility prevailed 

 all of April 13, but efforts were made to find the berg which had been 

 grounded in latitude 44°25' N., longitude 49°05' W. It was not found. 



The search on April 14 was planned so as to pick up the three bergs 

 sighted on April 11, and if possible, to relocate the grounded berg 

 last seen April 1 1 . The three bergs were found in the following posi- 

 tions: latitude 43°50' N., longitude 49° W., latitude 44°12' N., longi- 

 tude 48°49' W., and latitude 44°06' N., longitude 48°28' W. Over 

 the period of 3 days, two of these bergs averaged 16 miles a day and 

 one averaged 13 miles a day. The observed velocities and directions 

 of drift of these bergs are in excellent agreement with the calculated 

 stream lines shown on the current chart. The grounded berg was not 

 found. The Mendota drifted with the easternmost of these bergs the 

 night of the 14, and the next day, April 15, all three were relocated. 

 The easternmost of these three had drifted into the warm northerly 

 current and moved only 7 miles in a northeast direction. The other 

 two showed continued southerly drift in accordance with the current 

 chart but the observed velocity of movement, about 20 miles per 

 day, was in excess of what should be expected fi-om the density of the 

 isobaths. The search courses on the 15 were planned so as to cover 

 the 50-fathom curve from latitude 44°30' N., to latitude 43°12' N., 

 in a final effort to locate the large berg last seen aground on April 1 1 

 in latitude 44°25' N., longitude 49°05' W. The search was unsuccess- 

 ful so at sunset the Mendota returned to the southernmost ice, then 

 in latitude 43°29' N., longitude 48 '53° W. to drift for the night. 

 Due to rapid southward drift of these bergs carrying them south of 

 latitude 44° N., into west bound tracks C and D, it was recommended 

 to the Commander, International Ice Patrol Force on April 14 that 

 ice patrol be inaugurated for the season of 1937. Acting on tliis 

 recommendation the Commander, International Ice Patrol Force or-
