A letter to Dr. Alexander Wetmore, the Secretary of the Smithsonian Institution, from Dr. Leonard P. Schultz summarizing his work since the report on collections made at Eniwetok Atoll on June 12. Dr. Schultz briefly describes the lot of fish specimens that he will send to the United States National Museum in a few days' time and gives a cursory summary of the chronology of his work from June 12 to July 7, mentioning various travels and collecting activities, his work with Life Magazine Photographer, Mr. Goro, and the arrival and training of Capt. Earl S. Herald, who will be taking over Dr. Schultz's field work while he returns to the U.S. National Museum. Dr. Schultz also describes his experience of the A-bomb or Able test (a nuclear weapons test) on July 1, 1946, mentioning the procedure for watching the test, and then describing in detail what he saw of the explosion from a boat 20 miles off Bikini.

  • A 2-page letter to Dr. Alexander Wetmore from Dr. Leonard P. Schultz, . The Operation Crossroads was an expedition to Bikini and the northern Marshall Islands in 1946 under the auspices of the Department of the Navy. Schultz. Curator of Fishes at the National Museum of Natural History, was in charge of the biological investigation of the reef fishes in the area. His investigations centered on the relative abundance of fauna before and after the atom bomb tests. Specimens were collected for the purpose of comparison and to make possible a study of anatomical variations among the various island fish populations.
