The technical director of Railroads on Parade and the Golden Gate Exhibition's Cavalcade here tells the stories of five ""ghost railroads"", -- optimistically conceived, courageously executed, and dying when the mining booms which, for the most part gave them their reason for being, ceased to be. Gold, silver, lead --three reasons for these roads; politics another and a potent one. Mr. Kneiss has made the most of colorful and dramatic and human material; and the publishers have given us a beautiful book, liberally illustrated from old prints and sketches. Largely local interest, with plus sale nationwide to enthusiasts in this very special field.
