  • Lasso at the Ready
    Lasso at the ready September 11, 2019 Josh Valdez, who works in materials management at the Laboratory, sits on his well- trained horse, one gloved hand on the reins while the other grasps a rope ready to be deployed. Valdez looks over at a metal chute that contains his quarry, a large steer. On the other side of this chute is his roping partner, who in turn looks over and gives Valdez a quick nod. At Valdez’s command, the chute’s door flies open and the steer breaks out running. Seconds later, Josh sprints his horse forward and lassos the steer’s horns or neck, tightening the other end of the rope against the saddle’s horn. Valdez then uses his horse to turn the steer slightly sideways, enough so that the animal kicks up his hind legs. That’s when his partner who comes from the other side launches his own rope, catching the steer’s kicking legs. “Team roping is the one true team competition at a rodeo,” explains Valdez. “It requires close cooperation and timing between two ropers and their horses. The goal of team roping is to catch a steer in the quickest time possible.” Although amateur and professional rodeos feature team roping as a sport, the skills learned to rope and control cattle remain an integral part of ranch life. “Team roping started back in the day when cowboys needed to catch steers either to treat injuries or to brand their hides,” says Valdez. “Large steers are much too tough to handle for one person, so that’s why two ropers and two horses are used.” Valdez was 14 years old when he started participating in team roping.

  • Charrería: the Artisanship of Mexican Equestrian Culture
    Arte en la Charrería: The Artisanship of Mexican Equestrian Culture Educational Program by International Arts & Artists Table of Contents: I. What is Charrería? II. Events of the Charreada III. The origins of the Charreada IV. About the Exhibition V. Discussion Topics VI. Resource List VII. Glossary I. What is Charrería? Charrería is a Mexican cultural tradition that stems from the Spanish-inspired charreada. The charreada is a festive event that is similar to an American rodeo in its variety of competitive equestrian activities. Like the American “rodeo culture,” Charrería extends beyond horses and riders to include aspects such as costume, music, and food that bring a uniquely Latino culture to a sport that has its roots in Spain. The charreada began in Mexico in the 16th century when horses were introduced by the Spanish. As the Spanish tried to develop Central America for their own economic gain, they created an entire culture centered around agriculture and ranching in the haciendas they constructed. This is the culture that is reflected in Charrería. Although the main event is foreign-inspired, the culture reflected in the clothing, saddles, belts, hats, and spurs is largely inspired by traditional indigenous art. The Charrería has endured over five centuries because of the strength of the skills, sensibilities, and traditions that transcend regional and generational differences. Fearing the eventual loss of the Charrería culture, a group of charros, or the “cowboys,” who participate in the charreadas, united and formed various associations to preserve and promote this national culture. The Federación Mexicana de Charrería was founded in Mexico City in 1933 to govern the different charros associations that emerged.

The most important tools were his horse and catch rope. Erickson himself worked for eight years as a roping cowboy and has written other books on the West; he spent seven additional years re­ searching Catch Rope. Although relying heavily on anecdote, Erickson carefully notes his sources and is critical of writers who make undocumented claims. The book mixes his­ torical analysis with tall and not-so-tall tales, interviews, and personal experience, all to communicate both the method and the mad­ ness of the roping cowboys. Using secondary accounts, Erickson suggests the antiquity of the catch rope (what we green­ horns call the lasso or lariat, terms Erickson rarely uses).

  • HORIZONS of the WESTERN SADDLE 4 Richard E
    MAN MADE MOBILE Early Saddles of Western North America <. HSKIS^ Richard E. EDITOR SMITHSONIAN INSTITUTION PRESS SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given sub­ stantive review.

Thousands of years earlier there had been horses, but they disappeared. Since there were no cows, there were no cowboys. Of course, today there are cowboys. It is all because of Christopher Columbus.
