Arctic exploration ; Indo-European languages

SEGMENT 1: Arctic Exploration. Sir Hubert Wilkins, the first person to explore the Arctic Circle in a submarine (in 1931), discusses the climate of the region and his unusual experiences in the submarine. The logistics of submarines are demonstrated with a model brought into the studio. Sir Hubert was a noted geographer and climatologist who served as consultant to the Quartermaster Research and Development Command of the U.S. Army. Highlights from his films on the historic submarine expedition are shown. SEGMENT 2: Indo-European Languages. Languages and their historical interrelationships as part of the Indo-European language group are examined by Russell F. W. Smith, dean of the University College, University of Chicago. Students from the International House in New York City, speaking in several of the Indo-European language groups, demonstrate the similarities and differences between their languages.
