Note 115 — Chapter IV

This, and not T’efira, is presumably the point south of Auderas where Barth saw “natron” encrustations on the ground (see Vol. I. p. 389). Salt or “ara” is collected at T’efira further east, but Barth would not have described “entering” the Buddei valley after seeing the “natron,” for the road past Auderas to T’efira winds down the Buddei valley.
