The evidence
“In the fall of 1857, Edward Searing, for two or three years previously a student and for one year an assistant teacher of Latin in Cazenovia Seminary, New York, came to the village of Union, in this county, and opened a private " English and Classical" school. With the exception of Evansville Seminary, then in a chrysalis state, there was at the time no school nearer than Janesville offering instruction in the intermediate and higher branches.”
