Consists of six letters sent from various correspondents to Baptist missionary Abilone ("Abel") Bingham (1786-1864) during his time among the Seneca people at the Tonawanda Reservation in New York and the Anishinaabe (Ojibwe) at Sault Ste. Marie in the Michigan Territory. The earliest letter was dictated by a Seneca (Haudenosaunee) leader referred to here as Captain Billy (also known as Little Billy, Tishkaaga, Gishkaka, Juskakaka, Jishkaaga) to James Long. The letter is addressed to Bingham and the Chief of the Towanda Reservation (John Littlebeau) and discusses his support for Bingham's efforts to establish a school and also references strong opposition from other Seneca leaders. There is also a letter from Leonard Hator recounting his travels from New York to Michigan, describing missionary activities at the Carey Mission, and discussing the implications of recent U.S. treaties with the Potawatomi (Bodéwadmi) and Miami (Myaamia) people. Another letter from Isaac McCoy (1784-1846) from the Carey Mission discusses McCoy's efforts to convince the U.S. Congress to forcibly remove Indigenous Americans westward. There is also a letter from M.R. Johnson, a former student, describing his life among the Odawa (Ottawa) people near Traverse City; and a letter from Bingham's son, Judson, and his guardian, Arthur Lamb, relating Judson's experiences attending the Hamilton Academy. The last letter is from Samuel S. Johnson, wherein he attempts to defend himself against allegations of sexual harrassment and stalking.
