Mrs. Elizabeth Johnstone, who writes the department on “Manners and Social Customs,” is the only daughter of the late Francis Gardiner, one of the early settlers of Washtenaw County, Michigan.  She was educated at the State Normal School, now the Normal College at Ypsilanti, and taught for several years after graduation.  In 1880 she married the late Robert Ferguson Johnstone, editor of the Michigan Farmer, and after his death became editor of the Household Department of that paper.  In 1895, the Farmer having passed into other ownership, she became a member of the Editorial Staff of the Detroit Free Press, where,—­continuing to write under the pseudonym of “Beatrix” she has become widely known through the vast circulation of that paper.

Years of experience have enabled her to write on topics of interest to women with comprehension of their needs, and to answer social inquiries with exactness.
