to be of the same date, and erected by the same people as those already described. Several old gold-diggings are in the vicinity. Altogether these ancient forts, that are so largely distributed over these regions, are most interesting, and when this country is more developed and better understood, they may lead to discoveries that may throw more light upon the subject. That the Portuguese did deal largely with the natives in gold is clearly established, and if all these ruined forts were their work, they must have occupied the country in very considerable numbers, which seems hardly likely, because there is no record of their having done so to the extent which these ruins show. The kingdom of Tarva is supposed to have been in these regions. I have not met with any ruins yet that would lead me to suppose they were once the palace of the Queen of Sheba. I do not think that walls six or eight feet thick, built of small hewn stone without mortar, would stand as perfect as they are the wear and tear of four thousand years, in a country subject to such storms as sweep over this region in the rainy season. The only relics I have found are broken pieces of pottery, containing much mica, and the well-worn stones the natives used to crush their corn, which must have been in use many years, as they are hollowed out almost like basins, and the round stone the size of a cricket-ball, much worn on one side in pounding the grain. One ancient grave I opened, but found nothing but a spear-head of iron, that crumbled to pieces when handled; the bones had disappeared. I may mention, when prospecting in the channels worn in the beds of the rivers by the water, I have found a great many copper beads mixed up in the gravel and sand, and a piece of silver, that looks like part of a bar, about half an inch square and an inch in length, that was also lying in the bed of the river close to the ruins of the old fort on the Ingwazi river.
