The Asbury Harpending papers (see last week's post) contain scores of ciphered telegrams and letters. While a key exists to help decipher the correspondence of the early 1870s, later telegrams are encoded according to a different system (and represent Harpending's continuing speculation on the mining stock market after the Diamond Hoax fiasco). The only clue to this system is the two-sided telegram reproduced below. On the reverse, Harpending decoded his associate's ominous words—"Idiom tudor," "I am afraid."
