This is a book I couldn't put down. Father de Smet deserves to be better known for his role in the early pioneer days and conversion of the Native Americans. He was pivotal in quelling the rising tide of war with the Indians, working with the Dept of the Interior, demanding better treatment of the tribes, and asking the government to honor their agreements with them. If Father de Smet had been heeded, the last stand of Custer would have been averted, as he was instrumental in getting Sitting Bull to agree to an early treaty.
As for his deprivations - sleeping openly in the mountains and plains, traveling an amount equal to many times around the earth while he cared spiritually and materially for the needs of the many tribes, in hunger and thirst - he counted it but little since his joy in "his children" was great, and the pursuit of souls for Heaven drove him with Divine abandonment. He didn't want honors or an administration job in civilization, but only to be with his Indians, who traveled sometimes for months to reach him and beg him to come back with them to their tribe and teach them about the Great Spirit.
This book leaves you wondering why Rome never canonized him, for he was truly a second St. Francis Xavier, and was known as such during his lifetime.
