This was formerly called the Stewart’s Flat District and with the Secret Ravine District formed District No. 9. In 1856 while Miss Powner was teaching, one of the Trustees became dissatisfied with the location of the school house, and started another in a miner’s cabin on Pennsylvania Ravine. This became known as the Stewart’s Flat District. A. H. Goodrich taught the first school in 1856. In 1872 its name was changed to Penryn. The district now has two departments–grammar and primary. Miss Octavis Wetmore has charge of the grammar, with thirty pupils enrolled. Miss Eliza Jamison has charge of the primary school with fifty enrolled. There are two rooms in the building, each 24x36 feet in size. One room was built in the fall of 1881 at a cost of $900. Both rooms are supplied with patent furniture. A. Ross is District Clerk.
