The county history of 1880 has no passage naming this settlement, which was common for the smaller places. Its township is covered in full.

Museums hold 259 specimens collected within 10 miles of Polo between 1897 and 1967: 247 Animalia, 7 Plantae, 3 Fungi, 1 Unrecorded, 1 Chromista. 12 distinct Species records are shown. Collected by A. Gaufin, A. R. Gaufin, A.R. Gaufin and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.
