This collection consists of a single letter written by F. Calkins, serving in Company B, 2nd Massachusetts Heavy Artillery during the American Civil War. Addressed to "Dear Friend," the letter was written at Newberne, North Carolina, on September 10, 1863. Calkins exalts the power of Christ, and he despairs that his fellow soldiers care only for things that are low and devilish and seek only to gratify their lusts and passions.
