The author is a South Dakota native. This historical biography details one of the large cattle companies that came from Texas to Dakota Territory at the turn of the century until the late 1970's. Forest and Lena Rose are the main focus in this adventure. Photos of each camp where they lived, as well as multiple other photos, document this journey. Cowboys who worked for the Diamond A Cattle Company tell stories that give us a glimpse into the cowboy culture of that time. There are also unsolved mysteries, sections that will make you laugh and sections that will bring tears to your eyes and a lump in your throat. One Appendix offers insight into the dissolution of the Diamond A Cattle Company with the inclusion of the owner's Last Will and Testament. There is controversy and unfairness to be discovered here! The other Appendix shows how Lakota (Sioux) Allotments were used by the Diamond A and how much the allottees were paid for that use. There is even a document which shows that the BIA gave an Allotment to Cap Mossman, a non-Indian. Now how did that happen? This section also compares grain prices from that time to current prices. Many original receipts are shown to document monetary items. It is hoped that this section will spark the interest of descendants of allottees to do further research.
