Baguales and Cimarrones- terms used to describe a wild or feral horse in Argentina. This term was also used in Chile in the early colonial days, even though these herds were not truly wild but rather extensively managed horses of private ownership. This method of production disappeared much earlier in Chilean history.

Bandeirantes- slave traders that raided missions to capture and enslave more submissive natives. They were responsible for continuous attacks on a good number of the successful livestock-producing Jesuit missions in central South America. Most of the missions held their ground until they were banished from the New World by the Spanish crown, as they saw their success as a threat to its empire-building.

Bastarda- a style of riding that also maintained the full leg contact with what was essentially a straight leg posture, while bringing the heel of the foot under a hip that was placed nearer the pommel of the saddle. This created a more logical vertical column of rider weight distribution. More importantly, it also created a deeper and more erect seat that gave rise to the classical three-points of contact, at the two seat bones and the narrow bony ischium that unites the two sides of the pelvis under the rider’s crotch.

Bética- this was the name given to the area of Andalusia during the Roman occupation of the Iberian Peninsula. That fact that the Romans treated southern Iberia (Bética) and northern Africa (Mauritania) as one showed the cultural similarity of the two areas that also shared a similar horse type.

Boleadoras- these are leather-covered round stones that are tied to a leather strand that unites two or three strands at a common union. One “ball” was held in hand and the other one or two balls were whirled around overhead while chasing an animal that was to be immobilized. The “boleadoras” were thrown by calculating hands, projecting the rotating strands towards the legs of the target prey, where the ball and strands wrapped around the legs, bringing the animal to the ground. The boleadoras were also used as a weapon in hand-to-hand combat, where one ball was held steadfast to the ground by placing the strand between the warrior’s toes and the other two strands were held in each hand whirling in a forward windmill motion to maim the enemy with the hard strike of the balls.

Bombachas- these are baggy trousers similar to Arabic or Cossack pants. The gauchos of Argentina adapted them in the 19^th century, replacing the chiripá in an era when they were trying to substitute the gaucho image with prefabricated goods.

Bonete Huicano or Molino- this is a bonnet that had a short conical crown with a short flat and thick brim. Similarly styled hats can be seen in Mongolia, the Barbary Coast and even in the “goyezco” performance costume of the Andalusian Royal School of Equestrian Arts. Other hats had a short, fallen brim all the way around the conical crown, while some seemed to have no brim whatsoever. These felt hats were usually white, black or blue in color, and were most representative of southern central Chile.

Bosalillo, Piquera, Jociquera or Muserola- all these terms are used to describe a cavesson. They can be made of leather, rope or metal.

Botas de Potro- these are soft-leathered boots with no soles that were made from the leg and hock skin of young colts. The point of the hock is the heel of the boot, and the far end of the boot was open, exposing the toes of the rider that often used them to support various types of toe stirrups. These boots were the traditional footwear of gauchos.
