An important addendum to the Thwaites collection of _Early Western Travels_ is "The Southwest Historical Series," edited by Ralph P. Bieber--twelve volumes, published 1931-43, by Clark, Glendale, California. The stampede to California that began in 1849 climaxed all migration orgies of the world in its lust for gold; but the lust for gold was merely one manifestation of a mighty population's lust for life. Railroads raced each other to cross the continent. Ten million Longhorns were going up the trails; from Texas while the last of a hundred million buffaloes, killed in herds--the greatest slaughter in history--were being skinned. Dodge City was the Cowboy Capital of the world, and Chicago was becoming "hog butcher of the world." Miller and Lux were expanding their ranges so that, as others boasted, their herds could trail from Oregon to Baja California and bed down every night on Miller and Lux's own grass. Hubert Howe Bancroft (1832-1918) was massing in San Francisco at his own expense the greatest assemblage of historical documents any one individual ever assembled. While his interviewers and note-takers sorted down tons of manuscript, he was employing a corps of historians to write what, at first designed as a history of the Pacific states, grew in twenty-eight volumes to embrace also Alaska, British Columbia, Texas, Mexico, and Central America, aside from five volumes on the Native Races and six volumes of essays. Meantime he was printing these volumes in sets of thousands and selling them through an army of agents that covered America. Collis P. Huntington (1821-1900) was building the Southern Pacific Railroad into a network, interlocked with other systems and steamship lines, not only enveloping California land but also the whole economic and political life of that and other states, with headquarters in the U.S. Congress. Then his nephew, Henry E. Huntington (1850-1927), taking over his wealth and power, was building gardens at San Marino, California, collecting art, books, and manuscripts to make, without benefit of any institution of learning and in defiance of all the slow processes of tradition found at Oxford and Harvard, a Huntington Library and a Huntington Art Gallery that, set down amid the most costly botanical profusion imaginable, now rival the world's finest.
