Seventy-Five Years in California spans the 19th century, offering William Heath Davis’ view of California’s Pastoral Period. He gives readers a unique look at the disintegration of missions, the rise of the rancheros, the American Invasion, the Gold Rush and the adoption of the territory as a state. Davis himself had an interesting personal history, having been born in Hawaii in 1822, raised in Boston, traveled a great deal by sea, and became one of the most prominent merchants in San Francisco by 1845. The California Gold Rush really was a bonanza. Between 1849 and 1855 the miners gathered more than $400 million dollars; once adjusted, it is a sum today reaching into the trillions. It was a social phenomenon marked by the carnivalesque. In his work Roughing It (1872) Mark Twain’s protagonist remarks as his brother heads West, Pretty soon he would be hundreds and hundreds of miles away on the great plains and deserts, and among the mountains of the Far West, and would see buffaloes and Indians, and prairie dogs, an antelopes, and have all kinds of adventures, and may be get hanged or scalped, and have ever such a fine time, and write home and tell us all about it, and be a hero…And by and by he would become very rich, and return home by sea, and be able to talk as calmly about San Francisco and ocean, and ‘the isthmus’ as if it was nothing of any consequence to have seen those marvels face to face. Go they did to the Land of Golden Dreams, in the largest internal migration in American history, and the adventures and tragedies have created a large and memorable literature.
