A term of Spanish derivation applied to the business of rearing cattle, as carried on in the southern and western States of America; vast herds of cattle in a half-wild condition are raised on the wide stretches of prairie land, and are tended by "cowboys," whose free, adventurous life attracts men of all sorts and conditions.
