In 1855 I observed similar fossils in banks of gravel in transitu all down the Zambesi above Kebrabasa; and about 1862 a bed of gravel was found in the delta with many of the same fossils that had come to rest in the great deposit of that river, but where the Zambesi digs them out is not known.

In its course below the Victoria Falls I observed tufaceous rocks: these must contain the bones, for were they carried away from the great tufa Lake bottom of Sesheke, down the Victoria Falls, they would all be ground into fine silt.

The bones in the river and in the delta were all associated with pieces of coarse pottery, exactly the same as the natives make and use at the present day: with it we found fragments of a fine grain, only occasionally seen among Africans, and closely resembling ancient cinerary urns: none were better baked than is customary in the country now.

The most ancient relics are deeply worn granite, mica-schist, and sandstone millstones; the balls used for chipping and roughing them, of about the shape and size of an orange, are found lying near them.

No stone weapons or tools ever met my eyes, though I was anxious to find them, and looked carefully over every ancient village we came to for many years.
