The evidence
“one in their municipal affairs, and under the town government township system I became superintendent of the schools and town clerk and much interested in about every part of the local government. In 1853 I was elected a member of the School Board and have continued a member ever since. In that line I have had the satisfaction of seeing our schools promoted from a few dozen scholars assembling in a very small school building to a half dozen houses, one of which is valued at nearly one hundred thousand dollars.”
