The Old West comes alive through photographs made in the Arizona Territory from its beginning to statehood. Jeremy Rowe, a well-known Arizona photo historian, has combined his unique collection of photographs with his rendering of the history of photography in Arizona, opening a window into one of the most colorful chapters in our western heritage. In addition, the book includes the most comprehensive listing of photographers working in Arizona from 1850 to 1920 together with biographies of each and sources utilized in gathering the biographical information.

Topical files, miscellaneous correspondence and reports, and business record books, 1886-1916; include files of librarians/directors/deans Theodore W. Koch, William W. Bishop, Warner G. Rice, Frederick H. Wagman, Richard Dougherty, Robert M. Warner, Don Riggs, William A. Gosling, and Paul Courant; also assorted papers of earlier librarians, Andrew Ten Brook and Raymond C. Davis.

This book brings together, and integrates the three principal areas of environmental engineering water, air, and solid waste management. It introduces a unique approach by emphasizing the relationship between the principles observed in natural purification processes and those employed in engineered systems. First, the physical, chemical, mathematical, and biological principles that define, measure and quantify environmental quality are described. Next, the processes by which nature assimilates waste material are discussed and the natural purification processes that form the basis of engineered systems are detailed. Finally, the engineering principles and practices involved in the design and operation of environmental engineering works are covered at length. Written in a lucid style and offering abundant illustrations and problems, the book provides a treatment of environmental engineering that can be understood by a wide range of readers.
