Renowned naturalist Robert Cushman Murphy signed on for the second half of the cruise of the Daisy, hunting sperm whales in the Atlantic, from June 1912 to May 1913. His official title: assistant navigator. Murphy photographed the voyage, and developed his pictures aboardship with sea water. Here they are in a pictorial narrative that tells of the hunt, leisure-hour pursuits (scrimshaw), beasts of sea and air-albatross, boat gear and fellow seamen. In conclusion he reprints his log entry for ""the most exciting day of my life"" fighting a whale. Of incidental interest as a period piece.
