their legs with trudging over mountain ridges or scrambling through the
dense thickets of the rugged land west of Sofala. The Arab traders were

seacoast. It was an exceedingly difficult country to penetrate, and the
savage natives were jealous of any approach, if they did not stubbornly
bar the way and murder intruders.
