For a period of thirteen years (1898-1911), she was State secretary of the Loyal Temperance Legion of West Washington W. C. T. U.

This move was far more dangerous than any direct attack could have been, and the call was urgent for another campaign of public meetings and large expenditures for speakers and literature to thwart this approach.
During the same year, the W. C. T. U. built and equipped a new White Shield Home, a maternity hospital for unwed mothers,[4] in Tacoma, Washington.
