The evidence
“Messrs. Alden, Woodward and Woodruff successively became the subsequent managers of the institution, and, about 1855, the property was purchased by the city and converted to the uses of a public school, being generally known thereafter as the Janesville Free Academy, until the confines of its walls could no longer accommodate the pupils who sought admission. It was then torn down, and the imposing edifice known as the Central School was erected upon the site.”
