As I had forgotten to take with me from Khartùm a mosquito-net, or gauze bed-curtains, for which I had no use there on account of the heat, to keep off these tormentors, there was nothing for it but submission. Neither had I thought of leather gloves, unbearable in the hot climate here, but which would have been at this moment of essential advantage, for I was not only obliged to have a servant before me at supper-time, waving a large fan, made of ostrich-feathers, under my nose, so that it was necessary to watch the time for seizing and conveying the food to my mouth, but I could not even smoke my pipe in peace, though keeping my hands wrapt in my woollen Burnus, for the gnats not only stung through it, but even crept up under it from the ground. The blacks and coloured men were equally ill-treated by these hungry and impudent guests; and all night long might be heard the word “Bauda,” furious abuse against them, and flappings of ferdas to keep them off; but in spite of this, the face and body were as if bestudded, and swollen up with boils. The Baudas resemble our long-legged gnats, although their proboscis, with which they bore through a triple fold of strong linen, appears to me longer. Their head is blue; the back dun-coloured, and their legs are covered with white specks, like small pearls. Another kind has shorter and stronger legs, a thicker body, of a brown-colour, with a red head and iris-hued posteriors. The crew are quite wearied from sleepless nights, and rowing must be given up if the calm continues, although we find ourselves in a canal whose water propels us so little that we do not cast anchor. Here I got a specimen of the gigantic rush (_papyrus antiquus_) before mentioned. The stalk is prismatic, somewhat rounded, however, on one side; it runs in a conical form, to the length of from ten to twelve feet, and bears on the top a corolla like a tuft of reeds, the ray-formed edges of which branch out, and are more than a span long: the greatest thickness of the stem is one inch and a half, and never less than half an inch thick, and under the green rind there is a strong pith. Subsequently, however, I saw this papyrus, which our Arabs were not acquainted with, from fifteen to twenty feet long, and two inches thick, so that the longer reeds on the top shot forth from their little clusters of flowers and seeds, five to six new spikes, the length of a span. The _Ambak_ was _known_ to the old Egyptians; there is no doubt, therefore, that it, as well as this rush, was split, glued to one another, and used for a writing material, because it afforded the advantage of a greater extent of surface.
