Book excerpt: Historians of the American West, perhaps inspired by NAFTA and Internet communication, are expanding their intellectual horizons across borders north and south. This collection of essays functions as a how-to guide to comparative frontier research in the Americas. Frontiers specialist Richard W. Slatta presents topics, techniques, and methods that will intrigue social science professionals and western history buffs alike as he explores the frontiers of North and South America from Spanish colonial days into the twentieth century. The always popular cowboy is joined by the fascinating gaucho, llanero, vaquero, and charro as Slatta compares their work techniques, roundups, songs, tack, lingo, equestrian culture, and vices. We visit saloons and pulperias as well as plains and pampas, and Slatta expertly compares clothing, weather, terrain, diets, alcoholic beverages, card games, and military tactics. From primary records we learn how Europeans, Native Americans, and African Americans became the ranch hands, cowmen, and buckaroos of the Americas, and why their dependence on the ranch cattle industry kept them bachelors and landless peons.
