"Among the An-ko-me-nums, or Flathead Tribes of Indians of the Pacific Coast" by Rev. Thomas Crosby is a historical account written in the early 20th century. The book explores the experiences and struggles of the An-ko-me-nums, a branch of the Flathead Indians, focusing on the missionary work aimed at their spiritual and cultural upliftment. It delves into the social dynamics, challenges, and transformations faced by these tribes in the context of European contact and colonization. The opening portion of the book sets the stage for understanding the Flatheads' rich cultural heritage, including their customs and practices, as well as the missionaries’ motivations for their work. It introduces the historical context of early traders and explorers, who inadvertently influenced the natives’ lives, leading to their search for spiritual guidance and literacy through the "Book of Heaven." The text describes the initial mission to bring Christianity to the tribes, highlighting the heart-wrenching tales of native leaders who sought knowledge of the white man's God but encountered disappointment along the way. This narrative establishes a foundation for the subsequent chapters, which promise to explore further the complexities and challenges of cultural exchange between the missionaries and the Native Americans.
