The Faith-Promoting Series began in 1879 with the publication of this book, My First Mission. At that time George Q. Cannon, who was a member of the First Presidency, desired to produce a series of books that would both teach faith and other important gospel principles as well as be entertaining enough that youth would be willing to read them. The results were some of the most important and widest read books in the early-LDS cannon.
String of Pearls, book two of the Faith-Promoting series is a collection of missionary experiences, revelation, and beginnings. The first section of this book is the account of an emigrant who lived among the Ponca Indians, a tribe east of the Mississippi in the Ohio River Valley. W.C.S. describes hardships that greatly increased his faith since he looked on his experience as an Indian missionary.
