Orrin Guernsey taught school in the new frame building.

The evidence

• “Thus at the "big ford" of the Rock river, within a few rods of the "big rock," from whose flat summit Mucketay Muckekawkaik (Black Hawk) harangued his braves, was founded in 1838 the first educational institution in Rock county and the Rock River valley. This log sehoolhouse was used until 1843, when another log house was occupied by the school until the erection of the red frame schoolhouse of the joint districts of Rock and La Prairie in 1844, a full half-mile east of the first log house. Daniel Nurse taught the school in the winter of 1841-42 and Mr. Benedict in 1842-43. Orrin Guernsey was the first teacher to wield the birch rod in the new frame building during the winter of 1843-44. Mr.”
