The Carson papers contain correspondence, newspaper clippings, outlines and drafts of campaign speeches.  The materials, dated 1915-16, document Carson's efforts to enlist a candidate in support of drainage of the Everglades, his efforts on behalf of the Farris campaign, and his views on the drainage issue.  Correspondence also provides information on the activities of other groups supporting the Farris campaign, including the Everglade Drainage and Development League, "the Commercial Bodies of Miami and Ft. Lauderdale" and the Boards of Trade of Dania and Pompano.  Additional letters and newspaper clippings provide supporting documentation on the role of the drainage issue in the 1916 gubernatorial campaign.
