GENERAL DESCRIPTION.
[Sidenote: Boundaries.]
The Anglo-Egyptian Sudan comprises that country which is bounded on the north by the 22nd parallel of north latitude; on the east by the Red Sea, Eritrea, and Abyssinia; on the west and south-west by a line running through the Libyan Desert (defined by the Anglo-French Agreement of March, 1899), by the Sultanate of Wadai, and by the line of rising ground forming the watershed between the Congo and Shari on one side, and the Nile on the other; and on the south by the Lado Enclave[4] and east of the Nile, the 5th parallel of north latitude.
The greatest length from north to south is about 1,250 miles, and from east to west about 1,080 miles. (Vide Appendix A for text of Frontier treaties.)
