Victoria falls

"After twenty minutes' sail from Kalai we came in sight, for the first time, of the columns of vapor appropriately called 'smoke,' rising at a distance of five or six miles, exactly as when large tracts of grass are burned in Africa. Five columns now arose, and, bending in the direction of the wind, they seemed placed against a low ridge covered with trees; the tops of the columns at this distance appeared to mingle with the clouds. They were white below, and higher up became dark, so as to simulate smoke very closely. The whole scene was extremely beautiful; the banks and islands dotted over the river are adorned with sylvan vegetation of great variety of color and form…no one can imagine the beauty of the view from any thing witnessed in England. It had never been seen before by European eyes; but scenes so lovely must have been gazed upon by angels in their flight.

David Livingstone, November 1855
