There are several pools of stagnant salt water in the town, which, I conceive, in a great measure, promote the advance of the summer fevers and agues. The burying-places are outside the walls, and are of considerable extent. In lieu of stones, small mud embankments are formed round the graves, which are ornamented with shreds of cloth tied to small sticks, with broken pots, and sometimes ostrich eggs. One of the burying-places is for slaves, who are laid very little below the surface; and in some parts the sand has been so carried away by the wind, as to expose their skeletons to view. Owing to the want of wood, no coffins are used; the bodies are merely wrapped in a mat, or linen cloth, and covered with palm branches, over which the earth is thrown. When the branches decay, the earth falls in; and the graves are easily known by being concave instead of convex. The place where the former Sultans are buried is a plain near the town; their graves are only distinguished from those of other people by having a larger proportion of broken pots scattered about them. It is a custom for the relations of the deceased to visit, and occasionally to recite a prayer over the grave, or to repeat a verse of the Koran. Children never pass within sight of the tombs of their parents without stopping to pay this grateful tribute of respect to their memory. Animals are never buried, but thrown on mounds outside the walls, and there left. The excessive heat soon dries up all their moisture, and prevents their becoming offensive; and the hair remains on them, so that they appear like preserved skins.
