John, the book is available on line for review. For instance in Chap 5 comes the references to elephants (mammoths) and horses. Descriptions of the forts are found in Chapt 10. Chapters 12 and 14 detail the wars.
Really John, do some research.
You claimed that two Spalding manuscripts exist or existed. Is this online book based on the manuscript that was discovered in 1885, or from a different manuscript?
If from a different manuscript, does it have Nephi and Lehi as main characters as was claimed in the 1834 Mormonism Exposed?
Why don't you give the link to the online book?
