ridge known as Kariemakaris; thence continuing following a straight line, still southerly, to the foot of the western spur of the hill known as Aoruma, and following the foot of that spur to a beacon; thence in a generally southerly direction following straight lines to the westernmost end of the small hillock known as Lewi Lewi, to the hillock known as Sumemerr (known to the Pokot as Sumaremar) to the hillock Morumeri, to the hill known as Kauluk, across the Kanyangareng River to Nongalitaba Hill, across the Kunyao River to the small hillock known as Lokwamor, to the hillock known as Kokas, to Korkurao Hill; thence to Sagat Hill and along the highest points of the rocky ridge (forming a continuation of Mount Riwa and known collectively by the Karamojong as Kogipie) known severally as Sagat (Karamojong) or Kogipie (Pokot), Moruebu and Karenyang; thence to the summit of the hill Muregogoi; thence following a straight line to the source of the River Maragat; thence by the centre of the River Maragat to its confluence with the river Maron; thence southwesterly by the foot of the northwestern slopes of Kassauria Hill to the western extremity of that hill; thence following a straight line southeasterly to the northeastern extremity of Mount Riwa; thence following the foot of the eastern portion of Mount Riwa to the source of the Kanyerus River (marked by a large tree); thence southeasterly following a line of cairns, approximately in a straight line to the confluence of the River Bukwa (Kibukwa) with the River Suam (Swam); thence following the thalweg of the River Suam, upstream, to the point where the more northwesterly of the two streams forming the River Suam (Swam) or Turkwell emerges from the crater of Mount Elgon; thence following a straight line southwesterly to the highest point of Mount Elgon (Sudek). From this point, the boundary continues following a straight line in a northwesterly direction to the Wagagai summit of Mount Elgon; thence following a straight line, southwesterly, to the source of the River Lwakhakha (also known as the Malaba); thence following the thalweg of the River Malaba to its intersection with the eastern side of the Majanji-Busia-Tororo road at Map Reference XR 2765 (Sheet NA-36-15); thence in a southwesterly direction following a line on the east side of and 100 feet distant from and parallel to the centre line of the said road to its intersection with the River Okame at Map Reference XR 2458 (Sheet NA-36-15); thence upstream following the thalweg of the River Okame to its confluence with the River Alupe; thence upstream following the thalweg of the River Alupe to a point at Map Reference XR 2453 (Sheet NA-36-15) marked by a boundary cairn; thence following successively in a southwesterly direction, a number of boundary cairns at distances from each other of 550 feet, 1,226 feet, 959 feet, 976 feet, 1,007 feet, 580 feet, 1,512 feet, 463 feet, 2,364 feet (on the northern
