It might at first sight be supposed that the food supplies were drawn chiefly from the extensive agricultural settlements of the Inyanga territory, on the northern slopes of Mashonaland, which drain through the Ruenga and its numerous affluents to the right bank of the Zambesi. This Inyanga district may be roughly described, from the archæological point of view, as an area of old aqueducts, of old terraced slopes, and of old ruins of a less imposing type than the Zimbabwe remains. In a notice of _The Ancient Ruins of Rhodesia_ contributed to the _Geographical Journal_ for April, 1902, I first drew attention to the surprising analogy, or rather identity, between these terraces and those of the South Arabian uplands visited by General E. T. Haig in the eighties. So close is the parallelism that Haig’s description might almost change places with Mr. Telford Edwards’ account of the Inyanga works quoted in _The Ancient Ruins_, p. 353 _sq._, as thus:— TERRACED SLOPES TERRACED SLOPES (SOUTH ARABIA) (SOUTH AFRICA) “In one district the whole “The extent of these ancient mountain side, for a height of terraces is astonishing, and 6,000 ft., was terraced from top there is every evidence of the to bottom. Everywhere, above, past existence of _hundreds of below, and all around, endless thousands of inhabitants_. It flights of terraced walls meet would be quite impossible to the eye. One can hardly realise convey any idea of the immensity the enormous amount of labour, of labour implied in the enormous toil, and perseverance which these number of these ancient terraces. represent. The terraced walls I saw at least 150 square miles are usually from 4 to 5 ft. in composed of kopjes from 100 to 400 height, but towards the top of ft. in height literally strewn the mountain they are sometimes with the ruins. A contemplation as much as 15 or 18 ft. They are of the enormous tonnage of stones built entirely of rough stone and earth rudely built into these laid without mortar. I reckoned terraces left me amazed. It on an average that each wall appears to be abundantly clear retains a terrace not more than that the terraces were for the twice its own height in width, purpose of cultivating cereals of and I do not think I saw a single some sort.

The terraces are all made very flat and of dry masonry, not of hewn stone.”
