Note 134 — CHAP. XIV.
Reading edition
In the account of the expedition of the Bórnu king Edrís Alawóma, of which I shall have to speak in the second volume, no mention is made of this salt-trade of the Tébu; but from this silence no conclusion can be drawn as to the non-existence of the salt-trade at that time. On the contrary, we may conclude from the interesting account of Edrísi (transl. Jaubert, vol. i. p. 117. f.) who certainly means to speak of the salt-trade of the Tébu country, although he uses the term “alum,” that this article formed a very important staple in remote times.
