It is remarkable that, having written one successful book, Dana did not seek further reward as a man of letters. Two Years before the Mast appeared in 1840, while its author was still a law student. Though at the time it created no great stir in the United States, it was most favorably received in England, where it paved the way for many pleasant and valuable acquaintanceships. The following year, Dana produced a small volume on seamanship, entitled The Seaman's Friend. This, and a short account of a trip to Cuba in 1859, constitute the sole additions to his early venture. He was a copious letter-writer and kept full journals of his various travels; but he never elaborated them for publication. Yet, long before his death, he had seen the narrative of his sailor days recognized as an American classic. Time has not diminished its reputation. We read it to-day not merely for its simple, unpretentious style; but for its clear picture of sea life previous to the era of steam navigation, and for its graphic description of conditions in California before visions of gold sent the long lines of "prairie schooners" drifting across the plains to unfold the hidden destiny of the West. California and her Missions It is not easy to realize that, during the stirring days when the eastern coast-line of North America was experiencing the ferment of revolution, the Pacific seaboard was almost totally unexplored, its population largely a savage one. But Spain, long established in Mexico, was slowly pushing northward along the California coast. Her emissaries were the Franciscan friars; her method the founding of Indian missions round which, in due course, should arise towns intended to afford harbor for Spanish ships and to serve as outposts against the steady encroachments of Russia, who, from Alaska, was reaching out toward San Francisco Bay. Thus began the white settlement of California. San Diego Mission was founded in 1769; San Carlos, at Monterey, in 1770; San Francisco, in 1776; Santa Barbara, in 1786. For the general guardianship of these missions a garrison, or presidio, was in each case provided. It was responsible not only for the protection of the town thus created, but for all the missions in the district. The presidio of San Diego, for example, was in charge of the missions of San Diego, San Gabriel, San Juan Capistrano, and San Luis Rey. So, likewise, there were garrisons with extensive jurisdiction at Santa Barbara, Monterey, and San Francisco.
