Craton C. Colclo, (current in 1911-12) postmaster at Carroll, was appointed to that position by President Cleveland, June 11, 1885, during the recess of the Senate. His appointment was confirmed by that body February 12, 1886. (He succeeded Eugene R. Hastings). Mr. Colclo, the son of James H. Colclo, a Carroll county pioneer, was born in Ohio in 1852. At one and a half years of age, his parents removed to Madison county, IA, and two years later to Carroll county.

In 1870 Mr. Colclo graduated at the Iowa State Agricultural College, and his sister Jennie graduated at the same institution in 1880. After his graduation Mr. Colclo followed teaching until the fall of 1881, when he was elected county superintendent of schools, and re-elected in the fall of 1883. He resigned that position in 1885 to enter upon the duties of postmaster.
