Robert's Mill School and Teacherage

This is a pic of the schoolhouse at the Roberts' mill camp west of Fortine, with my grandfather's (or someone else's?)
inscription below it. Presumably "the only teacherage in Lincoln County" is the building to the left and behind the school
(a teacherage, as I now know from life in rural BC, was a building built for the teacher to live in, since they were
usually brought in from someplace else). Presumably this is the schoolhouse mentioned in the Tobacco Plains book
that was moved into Fortine in 1920.
