I have only seen one photo of the "public" school and it was very grainy, I do not have a copy to share here.
But I recently noticed the still barely visible school in a two photographs of the Farm Cottage at Colony Farm.
The Stride Studios, New Westminster, B.C. 14 March, 1929 Vancouver Archives A23170
If you went past the location today, you would have no idea that there was a school there, it is completely forested over, and a walk through the area would give you few clues that there was a school there.

Very little information about the school can be found. In October 1916 Gilbert Mathewson, Dr. J.G. McKay and Gowan S. MacGowan were appointed school trustees for the next three, two and one years respectively. I did see some letters about the founding of this school, the discussion went back and forth, about who was going to pay for it, the Mental Health branch or the local School Board, it appears that the Mental Health branch kept control of the building, since it is on Hospital property; and they billed the School board for the students that were NOT living on the property. Originally the hospital wanted the school closer to the main hospital buildings, but the parents nearby wanted it nearer to the property boundary, because it was much quieter, and safer in their minds; this concession was met. No idea when this school was closed, must be in the 60's, early 1970's when the Cape Horn Elementary was completed.
Sadly the local school district 43 has done a terrible job of preserving their history.
