Clara Soule, who stands in the back, taught a daytime Americanization class for adult women at the North School in Portland.

In addition to literacy in the English language, Soule wanted to teach what she thought of as proper female American behavior.

"It is apparent that not a few [students] get their first glimpse of refinement in these classes," Soule wrote in the 1924 Annual School Report. "The vulgar, obscene expressions previously used in their conversations have dropped."
