Goerler’s edition has nothing to do with Antarctica other than Byrd’s having read about Scott’s death on returning from the South Pole:
p. 69, Saturday, April 17, 1926: Read [Robert Falcon] Scott’s diary of his trip to the South Pole where he writes just before he died when his fingers would hold the pencil no longer. It is a wonderful dramatic though modest and simple narrative of unequaled heroism.
