Note 52 — Chapter II

Richardson, who travelled through it south of Tripoli, notices its ‘features of sterility, of unconquerable barrenness.’ Richardson's Sahara, 1848, vol. i. p. 86; and see the striking picture at p. 409. The long and dreary route from Mourzouk to Yeou, on Lake Tchad, is described by Denham, one of the extremely few Europeans who have performed that hazardous journey. Denham's Central Africa, pp. 2–60. Even on the shore of the Tchad there is hardly any vegetation, ‘a coarse grass and a small bell-flower being the only plants that I could discover,’ p. 90. Compare his remark on Bornou, p. 317. The condition of part of the desert in the fourteenth century is described in the Travels of Ibn Batuta, p. 233, which should be compared with the account given by Diodorus Siculus of the journey of Alexander to the temple of Ammon. Bibliothec. Historic. lib. xvii. vol. vii. p. 348.
