The General Greene departed from Boston on March 31 and pro- 

 ceeded to St. John's where she arrived April 4. After suppUes and 

 fuel had been taken on, departure was taken from St. John's on April 

 8 for the purpose of maldng a current survey of the region immediately 

 eastward of the Grand Banks from the latitude of Flemish Cap south- 

 ward to about latitude 41° N. The work of collection of data began 

 on April 9 at station 2048, and was completed at station 2117 near 

 the Tail of the Grand Banks on April 19, after 70 stations had been 

 occupied. The resulting current chart, figure 25, was then constructed 

 and deUvered aboard the Pontchartrain 19 hours after the last station 

 had been completed. The General Greene then proceeded to St. 

 John's, arriving there on April 21. 



On May 6 the General Greene departed from St. John's for the pur- 

 pose of making a second current chart. The area surveyed was similar 

 to that covered by the April map. The work of collection of data 

 began on May 7 at station 2118 and was completed at station 2187 

 on May 17, after 70 stations had been occupied. The current map 

 made from this survey was completed within 24 hours after the final 

 station but deUvery aboard the Pontchartrain could not be effected 

 until the morning of May 19 because of rough weather. After the 

 current map, figure 26, had been delivered, the General Greene returned 

 to St, John's where she arrived on May 19. 



Departure was taken from St. John's on June 1 to make a third 

 current survey. In response to a dispatch from the commander of 

 the International Ice-Patrol force the program was so planned that the 

 work of collection would take about 6 days. As it was believed that 

 the greatest amount of information could be obtained in the stipulated 

 time from a survey of the area between about latitudes 43° and 46° N., 

 east of the Grand Banks, the work of collection was begun on June 2 

 at station 2188 and was completed at station 2234 on June 8 after 

 47 stations had been occupied. The resulting current chart is shown 

 in figure 27, As the Ice Patrol was discontinued for the season on 

 June 9, the ice-observation officer, Lt. G. Van A, Graves, transferred 

 to the General Greene which then proceeded to St, John's, 



A total of 187 stations was thus occupied during the Ice-Patrol 

 season. An additional 30 oceanographic stations were occupied on
