100 THE LAST CRUISE OF THE CARNEGIE 



applause. He spoke briefly of the previous cruises of the Carnegie, 

 and went on to describe the new program in oceanography. It 

 was apparent that the majority of the hsteners understood him, 

 for without fail his occasional humorous touches were greeted 

 with appreciative smiles or laughter. He closed his lecture with 

 lantern-slides and moving-pictures, and gave a running descrip- 

 tion of each subject as it was flashed on the screen. 



The final event of the meeting was the presentation to Captain 

 Ault of a magnificent volume, just off the press, commemorating 

 the hundredth anniversary of the Society. 



After the meeting, our party was entertained by the members 

 of the Geographical Society at a charming informal supper in a 

 large restaurant. A spirit of good fellowship reigned. We had 

 an opportunity for interchange of experiences with these inter- 

 esting people, who were all anxious to do anything they could to 

 further our jjlans and make our stay pleasant. 



On the following morning we visited the observatory at Potsdam, 

 leaving Parkinson there to complete intercomparisons of his 

 instruments. Paul left that day for a trip to Bavaria by plane, 

 and the others returned to Hamburg to receive the return visit 

 of the scientists who had entertained us in Berlin. The staff of 

 the Potsdam Observatory, the members of the Oceanographic 

 Society, and others, made this journey to inspect the vessel and 

 to offer suggestions based on their own experience. They were 

 all favorably impressed with working conditions aboard, and 

 many expressed a regret that they could not join us. 



Following these suggestions, we had the winch-head turned 

 down to hold about 10,000 meters of piano-wire for sounding 

 and for collecting bottom-samples. This modification would 

 make the sounding independent of the water-sample series. It 

 would allow us to check the sonic depth-finder by wire-lengths 

 as well as with pressure-thermometers, for it was not feasible to 

 reach depths greater than 5500 meters with the larger bronze 

 wire. The piano- wire was generously supplied by the Meteor 

 Expedition. They also gave us a glass-lined bottom-sampling 

 tube, which they had found useful in the South Atlantic. It is 

 superior to the snapper-type sampler, because it gives a vertical
