ANNOUNCING . . . 



The 115th series of free, illustrated 

 lectures for adults opens Saturday, 

 March 4, in James Simpson Theatre. 

 Variety, color, and adventure keynote 

 the new series, which begins in the icy 

 wasteland of Antarctica; continues onto 

 the tropical islands of the Caribbean, the 

 Pacific, and the Indian Ocean: makes a 

 stop at the historic country of Greece; 

 and finally winds up on the snow- 

 covered Austrian Alps. The travelogues, 

 all filmed in color, are presented each 

 Saturday during March and April under 

 the auspices of the Edward E. Ayer Lec- 

 ture Foundation. Each film is narrated 

 in person, and the lectures begin at 

 2:30 p.m. Reserved seats will be held for 

 Museum Members until 2:25 p.m. Here 

 is your spring travel itinerary! 



March 4 — The Penguin Egg 

 and IGY 



Carl Eklund 

 Washington, D. C. 



An isolated glacial outpost called 



The Spring Travel Lectures 



Wilkes Station, one of the United States 

 bases in Antarctica during the Inter- 

 national Geophysical Year, provides the 

 setting for this fascinating film documen- 

 tary by Dr. Carl Eklund about one as- 

 pect of I.G.Y. Eklund, who was scien- 

 tific leader of the experimental station, 

 has recorded in color the many interest- 

 ing activities of the "operation deep- 

 freeze" at Wilkes, including a perilous 

 descent into an Antarctic ice pit down 

 to a layer of ice formed almost two cen- 

 turies ago. One of the most unusual 

 I.G.Y. projects presented in the film is 

 the installation of a miniature broad- 

 casting station in a penguin egg for the 

 transmission of temperature signals. Ek- 

 lund brings to his program a knowledge 

 of the Antarctic based on a long personal 

 association with the area.

March 11 — The Quest Eternal 



Henry W. Briggs 

 Skowhegan, Maine 



A remarkable film of Maine's wild life 

 in its eternal quest for the fundamentals 

 of life — food, shelter, and the reproduc- 

 tion of species. Through the color cam- 

 era, we follow that quest, watching the 

 wild life of forest, field, and pond — deer, 

 bear, and moose; birds, flowers, and in- 

 sects. To highlight the story of the food 

 chain, the camera records the story of a 

 dead tree, which furnishes food for many 

 creatures. Among these is the Pidgeon 

 Horntail fly, whose large-headed larvae 

 gnaw tunnels through the wood while a 

 protozoatic organism within the borer's 

 body converts the chewed-up wood cel- 

 lulose into protein. This protein, in turn, 

 nourishes woodpeckers and many hu- 

 man tribes in tropical regions. We also 

 see the astonishing female ichneuman fly 

 drill through inches of dry, hard wood to 

 deposit her eggs on the same borers. And 

 the amazing details of pollination in 

 flowers like the cypripediums, the laurel, 

 and the Jack-in-the-pulpit reveal still 

 other aspects of the eternal quest. How 

 these living species — both plant and an- 

 imal — seek the essentials of life is traced 

 through the entire seasonal cycle of 

 spring through summer, and fall into 

 winter. 



March 18 — Wyoming 



Alfred M. Bailey 



Denver Museum of Natural History 



Possibly no area in the United States 

 offers more to travelers than Wyoming. 

 Certainly no one knows it better, or has 

 filmed it more beautifully, than Dr. 

 Bailey, Director of the Denver Museum 

 of Natural History. Those who have 

 heard him before in the Museum's lec-
