This glass button with a loop style back was recovered during excavations at the 2018 Kansas Archeology Training Program Field School at the Kaw Mission. The front of the button has a blackberry-like decoration with half ovals around the rim. The button back retains partially readable information about the patent date: "PAT'D -U- 28, 18--." The site, now called the Kaw Mission State Historic Site, was built over the winter of 1850 - 1851 by the Methodist Episcopal Church South as a school for boys in the Kaw (or Kansa) tribe. The site was acquired by the state of Kansas in 1951 and added to the National Register of Historic Places in 1971.
