The Morio (_Acocanthera Schimperi_) is a curious-looking tree with its bare stem, averaging about six feet in height, formed of several thin stems twisted round each other after the manner of a vine. Surmounting the bare stem is a spherical crown of leaves, giving it the appearance of those little toy trees supplied to children in Noah’s arks. It has a small leaf and small pink-and-white flowers, which have a delightful scent. The A’kikuyu and Wa’Ndorobo use the distilled sap of the roots for poisoning their arrows. It is also used by the Somalis for that purpose combined with the sap of another variety of the same species (_Acocanthera Ouabaio_) which grows in the Arl mountains of northern Somaliland. The resultant poison is the celebrated “Wabaio” of the Somalis. No other plant or tree will grow near the Morio, consequently they are met with only in little groups or as isolated specimens. About two miles from camp I reached a small stony hill. On the summit I discovered a small rudely constructed fort, built of flat stones, containing small huts of stone roofed with brushwood. It faced to the north, and I afterwards found that it was used by the A’kikuyu as a watch-tower when expecting a Rendili raid. From the top of this fort I obtained a good view of the surrounding country. To the north the ground sloped away in a long incline to the Waso Nyiro, the bed of which lies more than a thousand feet lower than M’thara at the point in its course due north at that place. Beyond the Guaso Nyiro showed dimly the shadowy outlines of Mounts Lololokwe and Wargasse, 7750 feet and 10,830 feet in height respectively. Further away to the north and east lay the desolate sandy wastes of Samburu or Galla-land. To the north-east beyond the Doenyo lol Deika (a hog-backed ridge 6200 feet above sea-level) the great plateau of Lykipia stretched as far as the highlands of Kamasia and Elgeyo. At the foot of the Kamasia highlands lies Lake Baringo, distant a hundred and twenty miles, the southern end of which is inhabited by the Wakwafi of Nyemps. Fifteen miles south of Baringo is Lake Hannington, discovered by, and named after, the late Bishop Hannington, who was murdered by the natives of Usoga in 1885. The water of this lake is lukewarm, and, being impregnated with mineral salts, is very bitter. The Lykipia Plateau is terminated on the north by the Loroghi Mountains, and on its eastern side by the Elgeyo escarpment, which, together with its southern continuation, the Mau escarpment, forms part of the eastern wall of the great “fault” in the earth’s crust which extends from the sea of Galilee, over 33° north of the Equator, down the valley of the Jordan, thence down the Red Sea, and southward through North-Eastern Africa to Lake Tanganyika, 10° south of the line, and which is known to geographers as the Great Rift Valley.
