The following paper was read out on December 11, 1871, before a meeting of the Royal Geographical Society, Major-General Sir Henry Rawlinson, President of the Society, being in the chair. Much light had been lately thrown upon the dark points of Eastern Africa, especially those which gather round the much-vexed Ethiopic Olympus, Kilima-njaro, by the labours of the Rev. Thomas Wakefield. This gentleman, we are informed (Preface by Mr Samuel S. Barton, General Mission Secretary, to ‘Footprints in Eastern Africa.’ London: Reed, 1866), was one of four missionaries sent out to Mombasah in 1861 by the United Methodist Free Churches under charge of Dr Krapf, who first established the now world-renowned ‘Mombas Mission.’ After a residence of five years he published the interesting series of ‘Notes on a Visit to the Southern Gálas’ above alluded to; and in 1866-7, accompanied by the Rev. C. New, he marched from Mombasah to Upokomo, on the Dana river. He is therefore an African traveller of some experience; and as he has evidently mastered the Kisawahili tongue, he is unusually well qualified to supervise and to correct the ‘Routes of Native Caravans from the Coast to the Interior of Eastern Africa, chiefly from information given by Sádi bin Ahedi, a native of a district near Gázi (Gasi Bandar?) in Udogo, a little north of Zanzibar.’ Especially advocated by my old and tried friend Mr Alexander Findlay, F.R.G.S., this valuable paper was published in the Journal of the Royal Geographical Society (pp. 303-339, No. xi. Vol. xl. of 1870), and I felt somewhat surprised that the extent of its importance has not attracted more attention in England. I will consider this addition to our scanty knowledge of one of the most interesting regions in tropical Africa under two heads—the philological and the geographical.
