(xraves, ice-observation officer, and the observer's party reported 

 aboard, and at 1505, July 2, the Mendota relieved the Pontchartrain 

 as Ice Patrol vessel. The Mendota remained with the southernmost 

 ice, observing its set and drift until July T, when the berg had be- 

 come so small as to no longer be a danger to navigation. On July 

 8 the Mendota scouted up the eastern slope of the Grand Banks in 

 tlie cold current from the tail to latitude 47°20' N. No ice was 

 sighted this day so it was recommended to headquarters that the Inter- 

 national Ice Patrol be discontinued for the season. At 1258, July 9, 

 headquarters' dispatch 0209-1028, approving this recommendation, 

 was received and the International Ice Patrol was discontinued for 

 the season at 1300, plus three time. All shipping was advised, along 

 with the usual ice information, that the Ice Patrol had been dis- 

 continued and no further broadcasts would be transmitted. This 

 information was repeated at regular intervals as long as the Mendota 

 remained in the Ice Patrol area. 



The General Greene was met in lee of Cape Spear, off Saint John's 

 Newfoundland, and Lt, G. Van A. Graves was transferred to that 

 vessel at 1250, July 9, to assume command for the post-season ocean- 

 ographic cruise. The Mendota proceeded to Norfolk, Va., arriving 

 there at 1318. July 13, 1935. (See fig. 18.)
