V One yellowfin on a long branch of the fourth basket from the reef 

 (about 1.5 miles). Current S, rather swift. 



VI Weather calm, no current, position of gear did not change. Almost 

 ail of the baits were untouched. 



VII 0.5 to 3 miles off the reef. Nothing to report. 



VIII 0.5 to 5 miles off the reef. Rapid current running NE along the 

 coast, somewhat slower offshore. Speed of current 0.5 to 2 knots. 

 One yellowfin on a lone branch, and one spearfish and one okisawara 

 /"unidentified eybiid_/ on short branches. 



IX 1 to 6 miles off the reef. 



Immediately after getting the gear in the water a 70-kan / 578.9 lbj/ 

 marlin was taken on a short branch of the section of line nearest the 

 reef. There had been heavy rain since the previous evening. The 

 current was NE, about 1.5 knots, slower offshore. 



X 1 to 6 miles off the reef. 



No catch. Occasional showers. 



XI 2 to 6 miles off the reef. 



With 16 baskets of line in the water, a spearfish was taken on the 

 ninth section of line from the reef. Current N, 1 knot. Strong wind, 

 showers. 



XII 1 to 2 miles off the reef. 



No catch. Slow NE current. Weather bad, occasional showers. 



XIII 16 sections of line used. Two yellowfin were taken on long branches 

 of the second and eight sections from the reef. Current NE, 1.5 

 knots. Weather calm but distant lightning was seen. Water tempera- 

 ture 50 fathoms below the surface was measured and found to be 26.3 

 C, identical with the body temperature of the tuna which had been 

 taken. Consequently it was considered that this was the depth at 

 which the tuna were swimming, and the hooks were lowered 10 fathoms. 



XIV 1 to 2 miles off the reef. 



One yellowfin was taken on a long branch of the second section of line 

 of eight sections used (two boats working together operated 16 sections 

 of line). Current following the coast N, 1.5 knots. Weather calm 

 with occasional showers. Beginning this time we attached ^loats to 

 only half of the float-lines and got better results. 



XV Operated 16 sections of line. Yellowfin were taken on the eighth 

 and the eleventh from the reef. One spearfish was taken on the 16th 

 section. The currents were irregular and the main line got tangled up. 



XVI Nothing to report. 



The log of the fishing operations is shown in the attached table.
