The Rev. Dr. Thomas McHutchin Cunningham (March 22, 1887 - March 3, 1979) wrote these letters to family members from April 14, 1918 to November 28, 1927. The letters detail his life as a minister in Texas and other locations. The letters are written from Stamford, Spur, Eliasville, Sherman, Gainesville, Orange, Boston (Mass.), Richmond (Va.), and Knoxville (Tn.). The letters detail church news, family life, and travel on the S.S. Leviaton in 1927 to visit London, Paris, and Jerusalem.

This booklet is primarily photographs of life on the S. M. S Ranch. Near the end are several text sections, the first of which states, "It is the design of the S. M. S. Booklet to give feeders and breeders both by picture and written word a comprehensive idea of our methods and breeding in which we have been so successful..." (p. 78). The first section gives an overview of the policies and buying options for the cattle company. Next, "Some Glimpses Into Ranch Life" gives an overview of how ranching works, defines ranching jargon, and gives several songs/poems that illustrate ranching. The third and final section, "Stock Farms and Small Ranches, From the Spur Ranch" includes photographs from Spur Ranch and a brief overview about the ranch and surrounding area.
