conditions producing a wire angle of 48°, it was found that the splice 

 was pulling apart. The station was completed without loss of 

 equipment or observations. As we were approaching shallow water, 

 repairs could not well be effected until we reached station 1718, when 

 the wire was respliced. The work of collection then progressed with- 

 out further incident and was completed near the tail of the Grand 

 Banks on June 21, 46 stations having been occupied. Within 23 

 hours after the last station had been taken the current chart, figure 19, 

 was delivered to the cutter on patrol and the General Greene proceeded 

 to St. Johns by way of the eastern edge of the Grand Banks. Arrival 

 at St. Johns was on June 24. 



A total of 129 oceanographic stations were thus taken during the 

 ice-patrol season. On an abbreviated northern post-season cruise 

 between Cape Farewell, Greenland, and southern Labrador-New- 

 foundland, 43 additional oceanographic stations were occupied be- 

 tween July 3 and July 15. The dynamic topographic chart based on 

 this post-season cruise is shown in figure 20. The data collected 

 at the 172 oceanographic stations occupied during the season and on 

 the post-season cruise are presented in the oceanographic table in 

 this bulletin. The data from the post-season cruise will be discussed 

 along with the results of the northern cruises of the Marion in 1928 

 and the General Greene in 1931, and 1933 in Bulletin 19, part 2. 



Other incidental data collected on the General Greene consisted of 

 barograms, sea-water surface thermograms, and about 500 sonic 

 soundings for which positions and correction data are available. 



The equipment was in general similar to that used during the 1933 

 season. Laboratory working space was enlarged by the removal of a 

 bulkhead formerly separating the laboratory from the oceanographer's 

 stateroom, the removal of the built-in bunks from the stateroom, and 

 the installation of a stanchion and a folding bunk. The repair of the 

 water bottle damaged during the 1933 season and the addition of 

 six new ones brought the number of Nansen water bottles to 18. 

 At the beginning of the season there were available 19 protected deep- 

 sea reversing thermometers and 10 unprotected thermometers. Of 

 these, 11 of the protected and 1 of the unprotected thermometers had 

 recently had their zero-points determined at the United States 

 Bureau of Standards, the remaining 17 having been newly received 

 from the manufacturers. During the season the work was somewhat 

 handicapped by the scarcity of thermometers in some of the tempera- 

 ture ranges. On June 26, however, the remainder of a group of 

 thermometers that had been contracted for were received in St. 

 Johns and an adequate number of thermometers of the necessary 

 ranges were available for use on the post-season cruise. All ther- 

 mometers were of Richter & Wiese manufacture. 



A new model Wenner saUnity bridge was received in St. Johns on 

 April 30. This new model embodied many of the improvements in
