during sea work, material captured by the trolling handlines was preserved 

 in the deep-freeze or measured aboard. In general, the sea was very smooth, 

 and working conditions were excellent. 



Shore work, which includes mostly the measuring and dissection of large 

 specimens of billfish was conducted at a very convenient site on the water- 

 front. An excellent workbench was available, as well as a crane for hoisting 

 large specimens directly from the Explorer to the workbench. A large 

 storeroom, for the use of the expedition, at the Grace Company building, 

 one block from the Hotel Prat and four blocks from our water-front 

 installations, was provided. 



The fourth and last cruise in northern Chilean waters was conducted in 

 the area west-northwest of Iquique, during July 5 and 6. Eight plankton 

 stations, spaced about 25 miles, were occupied during this cruise, which 

 covered 250 miles. 



In accordance with the shipping date of the Explorer to Peru aboard the 

 Grace liner Santa Rita, which had been set for July 10, field activities were 

 suspended on July 7 in order to prepare the cruiser for shipping. According 

 to Chilean law, the vessel and equipment had to be packed, inspected and 

 sealed by Customs from 2 to 4 days before shipping time. 



Peru 



The period, comprising July 13 to 17, was spent in Lima holding con- 

 ferences with government officials in connection with the expedition's 

 activities in Peruvian waters. Official documents clearing the Explorer for 

 operation in Peruvian waters, as well as Customs facilities were obtained. 

 Among others. Senator Manuel B. Llosa, Dr. Cristobal Vecorena, Director 

 of "Caza y Pesca,"' Mr. Robert O. Smith, Technical Advisor to Peru from 

 the Fish and Wildlife Service, Admiral G. Tirado, Peruvian Navy Chief of 

 Staff and Commander E. Zimic, Director Hydrographic Office of Peru, 

 were visited. 



Mr. Felipe Ancieta was appointed observer for the expedition by the 

 Director of "Caza y Pesca," and Lieutenant Commander Jose F. Baran- 

 diaran. Director of the Navy Department of Oceanography, was appointed 

 as observer by Admiral Tirado. Mr. Ancieta is ichthyologist for the Peru- 

 vian government and has received some training at the University of 

 Michigan, mostly in fresh-water fishes. Commander Barandiaran, physical 

 oceanographer, who received his training at Scripps and at the U. S. Hydro- 

 graphic Office, was of the greatest possible assistance to the expedition, 

 particularly in view of his own contribution to the hydrographic knowledge 

 of the area. Through the courtesy of Commander Barandiaran the oppor- 

 tunity was taken of visiting the well equipped oceanographic laboratory of 

 the Peruvian Navy at Caliao.
