Our winter expedition to Willow Clump Island filled us with a wholesome respect for Arctic explorers. If we could find it so uncomfortable with the thermometer only at 10 degrees above zero, what would it be to endure a temperature of 40, 50 or even 60 degrees below zero? We were interested to learn how they managed to stand it. This led to a study of the subject in Mr. Van Syckel's library.
