In the book, which takes place between 1834 and 1836, Dana gives a vivid account of “the life of a common sailor at sea as it really is”. He sails from Boston to South America and around Cape Horn to California. Dana’s ship was on a voyage to trade goods from the United States for the Mexican colonial Californian California missions’ and ranchos’ cow hides. They traded at the ports in San Diego Bay, San Pedro Bay, Santa Barbara Channel, Monterey Bay, and San Francisco Bay.

You get a real idea of what life was like along their route – told like a novel, but completely historical.

Dana arrived in Alta California when it was a province of Mexico, and no longer Spanish colonial Las Californias. He gives descriptions of landing at each of the ports up and down the California coast as they existed then. The ports served (south to north) the Mission San Diego de Alcalá, Mission San Juan Capistrano, Pueblo de Los Angeles (and Mission San Gabriel Arcángel), Mission Santa Barbara (and Presidio of Santa Barbara), Presidio of Monterey, and Presidio of San Francisco with their very small settlements and surrounding large Mexican land grant ranchos. He also describes the coastal indigenous peoples, the Mexican Californios’ culture, and the immigrants’ and traders’ influences from other locales.
