In 1882, the Northwestern Kansas Teachers met in Beloit. Copley spoke about Kansas Day, and a Kansas Day booklet was printed. Since then, Kansas Day has been observed in Kansas schools.

The Governor of Kansas and the Kansas Legislature issue special Kansas Day proclamations. The Kansas state song "Home on the Range" is performed. A Kansas Day cake is presented at the Kansas State Capitol.
My 2nd-great-grandfather's brother Sven T. Anderson (Sven Troedsson) was living in Kansas by 1885. His children probably participated in Kansas Day exercises at school.
