The town of Tarrangotté is arranged with several entrances in the shape of low archways through the palisades: these are closed at night by large branches of the hooked thorn of the bitter bush, (a species of mimosa.) The main street is broad, but all others are studiously arranged to admit only of one cow, single file, between high stockades. Thus, in the event of an attack, these narrow passages can be easily defended, and it would be impossible to drive off their vast herds of cattle unless by the main street. The large cattle kraals are accordingly arranged in various quarters in connection with the great road, and the entrance of each kraal is a small archway in the strong iron-wood fence, sufficiently wide to admit one ox at a time. Suspended from the arch is a bell, formed of the shell of the Dolape palm-nut, against which every animal must strike either its horns or back on entrance. Every tinkle of the bell announces the passage of an ox into the kraal, and they are thus counted every evening when brought home from pasture.
