Note 5 — PREFACE.

“The people of Ágades at that time (the last quarter of the last century)—though Ágades then belonged to the Cashna empire—were annually permitted to load their immense caravans with the salt of Bornou, from the salt lakes of Demboo” (the Tebu country?), “the merchants of Ágades giving in return for the article a trifling price in brass and copper.”—Lucas, Proceedings of the African Association, vol. i. p. 159.
