The collection is arranged in strict chronological order, 1894-1950. In gathering his materials, Herfurth corresponded with the living participants in the above mentioned affairs; they in turn, sent him letters written in the period in which he was interested, and also gave him accounts of the events. No attempt was made to group the letters written in 1915 by members of the Class of 1910 with the letters they wrote to Herfurth 25-30 years later.
