"Memoir of the Proposed Territory of Arizona" by Sylvester Mowry is a historical account written in the mid-19th century. The book focuses on the Gadsden Purchase, detailing its geographical boundaries, natural resources, and the potential for settlement and development in the region. Mowry, who served as a delegate, provides insights into the area's mineral wealth, agricultural capabilities, and the ongoing conflicts with Indigenous populations, arguing for the region's separation from New Mexico and its organization as a distinct territory. In this memoir, Mowry presents a thorough examination of Arizona's resources, particularly emphasizing its rich silver and copper mines, alongside fertile agricultural land. He recounts historical explorations and the establishment of missions, while also reflecting on the struggles faced by the settlers due to Apache raids and the lack of governmental protection. The text serves as both an appeal for political recognition and a call to action for settlers, illustrating the economic potential of the territory and the urgent need for protective measures to foster its development. Mowry's passionate advocacy highlights both the promise and peril of life in the newly acquired territory. (This is an automatically generated summary.)
