Schools. — Prior to the erection of the borough of New Lebanon the territory was a part of sub-district No. 7, of Mill Creek Township. The first house was a two-story frame, about 24x30, and was erected by David Randall in 1855. On the 11th of March, 1858, it was determined to subdivide the lower room, affording advantages in the two rooms for smaller grades of public school pupils, and using the upper room for the purpose of a select school.
