This revised volume I is a compilation of information on Adventists establishing the church in New Mexico and El Paso, Texas, gleaned from secular and church sources of this time period. It weaves a story of how tuberculosis, railroads, and land grants impacted early members and workers who brought the Texico Conference into existence, and provided the foundation for where it is today. Despite losses and hardships, they pressed on to spread the gospel of Jesus. This book is a tribute to them.
