Reading brands followed a shared vocabulary in which a reverse letter differed from a tumbling one, a sideways letter was lazy, rounded angles made a letter running, wings made it flying, legs made it walking, and a letter attached to a quarter circle on the bottom was rocking. A character could swing from another, a square was a box, the upper half of a square was a bench, short horizontal lines were bars, long horizontals were sometimes rails, and shapes such as diamonds, triangles, circles, crescents, stars, crosses, rafters, slashes, and quarter circles kept their names. Connected letters or symbols were read together, as in a reverse FAK connected, and a rafter connected with other letters was usually called an open A. Around Murdo Mackenzie Roadside Park, which sixty years earlier had been the center of the Great White River cow country, the region stretched from Chamberlain to the Black Hills with no highways, railroads, or towns, only scattered post offices and tiny stores, few fences beyond garden plots, no big dams, and mostly grass, sky, cattle, and little homestead land. Many ranches held or claimed grazing rights on the Rosebud Reservation south of the White River down to Nebraska. Post offices included Cavite, Zickrick, Stearns, Whitfield, Lodge, and Black, and ranchers used distinctive brands such as Jim Clave's seven, slash, seven, Jake Hauseman's Circle D, Charles Pitan's Circle Cross, the Bowley boys' BOW, the Zoske Brothers' ZOS, John Zickrick's bar, six, bar, W.W. Anderson's Rake, Conner Thode Cattle Co.'s TJ connected, and Adam Smith's A bar S. The first post office in the area was established at Westover on White River on June 6, 1891, and the first Westover brand registered was Adam Smith's A bar S, used on cattle on both sides of White River.
