At the final session, Saturday afternoon, April 3, 1858, all the delegates signed the convention's proposed constitution, but several took the opportunity to make one last protest of the inclusion of "negro suffrage" because they believed their constituents opposed it and/or insisted that the instrument did "not extend the right of suffrage to negroes." This protest included Caleb May of Atchison County, the entire Linn County delegation (Addison Danford, Robert B. Mitchell, Thomas H. Butler, and Robert Ewing), and A. W. McCauslin of Jefferson County. The latter individual also expressed concern about the Education clause, "which appears to permit colored children to go to Common Schools with white children" and "the subject of negro immigration."
