“The home garden of Clifford[,] Bernard[,] and Elizabeth Bridges who use the fertilizer from the Rabbitry for their gardens.” Photo taken in Oregon, ca. between 1915 and 1918, via 4-H Photograph Collection, OSU Special Collections & Archives Commons on flickr.
The children are members of a local 4-H club, making a WWI victory garden. I think this is the Portland home (and children) of W.R. and Elizabeth Bridges. W.R. was a proofreader for The Oregonian.
