Eleven sheets of original pencil drawings, the work of the 1907-08 Boundary Commission. Much of the detail is now faint, and there is, naturally, more information on the British than on the French side of the Boundary. MRLG reference Original 606.

Nine maps at 1:250,000 scale on tracing linen. "Northern Nigeria-Anglo-French Boundary east of the Niger. To accompany Report of Joint Commission of Delimitation signed at Kaua, 25th February 1908". These are based on item 8, and were signed by the three British Commissioners and Capitaine Tilho, the head of the French Commissioners. MRLG reference Original 580.

Prints of item 9 were produced by the Ordnance Survey in 1908, designated TSGS 2388. They were probably monochrome, but MRLG does not hold copies of the 1908 printings. MRLG holds 1941 monochrome reprints, bearing the imprint 306/6/41. MRLG reference E39:2(1). They differ from item 9 in the following ways:
11.
(i)
All sheets are marked PROVISIONAL
(ii)
All sheets have a note on the significance of positioning of beacon numbers on the map.
(iii) Sheet I, the title sheet, carries the note, "These sheets are issued
provisionally and have no authority as a boundary map".
(iv) Sheet I also has two other notes, on place name pronunciation and spelling.
Other minor changes have also been made.
(v)
Fourteen maps, cartographically rather crude, at 1:200,000 scale. These are the maps signed by the 1907-08 Commissioners, Major O'Shea and Capitaine Tilho, in London on 19 February 1910, at the same time that they signed the Protocol. Despite their crude nature, therefore, they must be regarded as the most authoritative maps on the boundary. Clearly of French origin, longitudes are based on Paris, and they are entitled "Frontière Niger-Tchad; Niger-Chad Boundary" (i.e. River Niger to Lake Chad, not the modern Niger state-Chad state boundary). Sheet 1a is annotated "Map attached to the Report of the Joint Commission for the Delimitation of the Anglo-French Frontier East of the Niger, Northern Nigeria"; this means that item 9, a British map drawn in 1908, may possibly never have been submitted with the Commission's 1908 Report. Many place names on these 14 maps are clearly of French origin, with English versions in brackets, and there are generally many more names on the French side of the boundary. Why, when two years had elapsed since the Commission completed its fieldwork, it was necessary to use such crude maps to accompany an international agreement is something of a mystery. The originals are held in the Foreign and Commonwealth Office, MRLG holding one set of photocopies, reference E39:2(1A).
12. Original drawings, in black, blue, brown, and red, at 1:250,000 scale for the regular edition of series GSGS 1764. The northern Nigeria boundary appears on 15 of the sheets each 1o x 1° (cf. item 5 which is the provisional edition of this series, on different sheet- lines). The sheet numbers are as follows, with the IMW type sheet numbers adopted for the published sheets given in brackets.

51-N (ND-32/N)
51-U (ND-32/U)
50-R (ND-31/R)
51-0 (ND-32/0)
51-V (ND-32/V)

51-P (ND-32/P)
52-M (ND-33/M)
50-W (ND-31/W)

This mapping was based largely, but not wholly, on the work of the 1907-08 Boundary Commission. They must have been drawn in 1908, and several carry the lightly- pencilled designation "Geographical Section, General Staff No. 2388" which was finally allocated to the provisional boundary maps (item 10). The sheets carry notes
