Copper Mountain: Adventurous Days Among the Eskimos (1925)
White Jade (1930)
Fantastic Traveller (1931)
The Green Scamander (1934)
The Green Scamander seems to be the novel with lesbian content.
Meagher with Carolyn Smiley ran a Boston-based publishing house during the 1930s and 1940s publishing the magazine World Youth Today. In 1940, they moved to Los Gatos, CA and built a 15,000 square foot adobe house.
Barbara Grier and Constance Barker corresponded about Meagher; that correspondence is in the Grier Papers at the SFPL.
