The demand for sugar is high and some preparations must be made to 

 supply It in various forms because it is a source of energy. This was the 

 case on the research vessel, and it must be even more so on a regular 

 working vessel where over-exertion is unavoidable^ The need for alcoholic 

 beverages is extremely limited and does not require any general considera- 

 tion. During my recent tour of duty not one of the young fishermen or 

 engineroom men asked for liquor, an interesting fact which bespeaks a 

 change in the times. 



As a result of eating iisn guts from the catch cooked with miso half 

 of the crew suffered from vomiting and diarrhea (with headaches and belly- 

 aches). They all recovered fully within three days. In the low latitudes 

 bellyaches, even when not caused by food, are of frequent occurrence, and 

 it is essential to be prepared with medicines against them. During the 

 course of the operations one m.an hurt his leg. Accidents like this happen 

 from time to time and it is important to have ointments to apply in such 

 cases. 



B, Problems of the crew's welfare and recreation 



Some sort of recreational facilities are necessary in these 

 isolated areas where the climate is unfavorable. On this cruise all of 

 the m.embers of the crew were picked men, and we benefited by their 

 harmonious cooperation. On thinking it over thoroughly, however, these 

 good results v/ere due to the fact that we had gathered together the most 

 excellent men from various areas. But this is something apart from the 

 problem of recreational facilities. The leaders must study this problem 

 in advance and set up appropriate facilities both aboard ship and at the 

 base. Aboard ship suitable books should be provided, combining the 

 objectives of recreation and ideological guidance, and the men should 

 be given the opportunity to listen to the radio and phonograph. At the 

 base they should bj?- all means be given a chance to rest in comfortable 

 beds, and encouraged to take walks and exercise. After our return to 

 Jaluit the Chief of the District Office invited me to have the crew 

 sleep at the Japanese Club, a favor for which I can never thank him 

 enough. We were, however, so busy putting in order the materials left 

 over from what we had brought out the year before that on this cruise 

 we could only give the crew one day of rest aboard the ship, (end) 



Note: With the publication of this report in this journal taking place 

 a full year after the investigation which it describes, one cannot help 

 feeling some regret at its tardiness, however, one cannot but feel, on 

 the other hand, that the material is timely in view of the fever for 

 southward expansion which is gripping our fishing industry. On the basis 

 of this paper Kr. Kenzo Ikebe of the South Seas Government-General 

 Fisheries Experiment Station has stated in South Seas Fishery New^, 

 Volume Uy Number 2, that "the greater part of the catch consists of fish 

 in their seventh year, and fish older and younger than that are taken 

 only occasionally. The yellowfin tuna of the waters adjacent to Palao 

 and those of the waters south of the ^■arEhalls are migratory fish belong- 

 ing to the same stock." I wish to take this opportunity to offer my 

 thanks to him, and also to I't^ Ota, the editor of this journal, for 

 publishing this paper.
