The Somali Horn and Cape of Good Hope
                clamp a continent together.
                We fly and fly.
                A rusty waste separates
                the Tropics of Cancer and Capricorn
                from the green arbiter the Equator.
                Our plane shadows a Nile that curls
                like an adder, sluggish, clay-brown.
                The brown gives way to black at sundown.
                By sunup, there's here.
