“But you must know the class of sweet women—who are always so happy to declare “they have all the rights they want”; “they are perfectly willing to let their husbands vote for them”Mare and always have been numerous, though it is an occasion for thankfulness that they are becoming less so.”
—Eliza “Mother” Stewart (1816–1908)
