Wanted: Three scientists for expedition to South Pole; must know how to play exceptionally good bridge. If you should see an ad like that in your newspaper, bear in mind that the bridge playing requirement is just, as important a qualification as being a scientist. The authority is Dr. Thomas C. Poulter, director of the research foundation of the Armour Institute of Technology. He will be leader of a crew of four which will man the government Antarctic service’s "snow cruiser" next year in an expedition to stake the United States’ claims to mineral resources at the South Pole. He said he hasn’t chosen his crew members yet but when he does they’ll be bridge players. Poulter was second in command of Rear Admiral Richard E. Byrd’s Antarctic expedition during 1933-35, and is supervising construction of the "snow cruiser". It will be 55 feet long, have balloon tires 10 feet in diameter, carry an airplane on its roof and be equipped with all the fixtures of a scientific laboratory and a luxury trailer. It will have a cruising range of 5,000 miles and will be able to span crevices 15 feet wide. Poulter said he would be in charge of the cruiser’s crew until spring when Dr. A. F. Wade will take over as chief scientist of the expedition. "The crew will have to live closed up together for a year or longer and they’ll have to have the ability to get along well," he said. "From my experience on the Byrd expedition, I realize the ability to play bridge is important in that connection". "Wade is pretty good and I know I’ve never trumped my partner’s ace".
