Mrs. Henry Rowe Schoolcraft's husband was one of 19th-century America's best-known interpreters of Native American culture (Longfellow relied on his accounts in Hiawatha). In her "Dedication," Mrs. Schoolcraft identifies herself mainly as a wife, writing to satisfy her husband's wish for her account of "plantation life" in her "native state of South Carolina." Stowe's name comes up often enough to make it clear that she's also writing to contest Uncle Tom's Cabin. Her novel has only the merest trickle of narrative; it's essentially a series of speeches -- made by characters, the narrator, and published writers from whom she quotes extensively -- that combine a racist "ethnology" of the "African" with a partial reading of the Bible to insist, repeatedly, that God approves slavery as the best way to bring the savage to civilization and to Him.
