1.
(i)
2.
(ii)
A map which appears to be one originally signed by the Commissioners, being a composite one made from sheets 4 and 5 of Justus Perthes' map 'Afrika', 3rd edition, dated Sept 1892 (sheet 4) and October 1891 (sheet 5). At a scale of 1:4,000,000, it shows the 'Limite de l'Arrangement Commercial & Fiscal' between the British and French spheres of influence, from the eastern boundary of Liberia to the eastern boundary of Nigeria. MRLG reference E1:6(1).
Map 2 of the Convention Protocol, redrawn from item 1(i) with superfluous detail omitted. Printed as 1.D.W.O. No. 1355(b) in August 1898 by the Intelligence Division, War Office. MRLG reference E1:6(2). Reproduced in Hertslet as map 10.
'Anglo-French Boundary Commission 1902-3-4. Northern Boundary of Northern Nigeria as defined by Paris Convention of 1898', scale 1:2,000,000, designated TSGS 1923, printed by the Ordnance Survey in 1904. Held at MRLG in the library of record superseded maps. (11).
3.
'Map of the Anglo-French frontier in Borgu (on the west of the Niger) and of part of the Dallul Mauri', scale 1:1,000,000, designated IDWO 1518, heliozincographed by the Ordnance Survey in 1901. Based on Major Lang-Hyde's work whilst British Commissioner on the Anglo-French Commission which delimited the western boundary of Northern Nigeria in 1900. Held at MRLG in the library of record superseded maps.
4.
Original material from the 1902-04 Boundary Commission, described as 'Original Sketches by Boundary Commission (Anglo-French), Northern Nigeria, 1902-3-4'. It is practically all British material, mostly manuscript sketches, traces, and compilations at various scales. Several items show a boundary, but its relationship to the 1898 Convention line and to published mapping of the time has not been analysed. MRLG reference E39:e(1).
5.
The following provisional sheets of series TSGS 1764, Africa 1:250,000, Northern Nigeria, all compiled and published by the Topographical Section, General Staff in 1905, except sheet 61-C, which was compiled and published by the forerunner of TSGS, the Intelligence Division, War Office, in 1904. Sheets are 12° E-W by 1° N-S.
50-K, 50-L, 50-0, 51-1, 51-J, 51-K, 51-L, 52-1, 61-C.
These maps do not show the present-day boundary alignment; they probably reflect the alignment set down by the 1904 Convention. MRLG reference E1(11).
