Buffalo Bird Woman was a Hidatsa Indian born in 1839. This book is her reminiscences about the gardening of her and her tribe. She describe their gardening practices and the tools they used but also shares her memories of her youth and the traditional tools used by her elders. This is an excellent resource to understand traditional Native American agriculture.
