Note 22 — Chapter V · FROM MOMBASAH TO THE PANGANI RIVER.

Sheet X. from S. lat. 6° 38′ to S. lat. 4° 23′ (Tom Shoal) is the offending member in commission and omission. It places Chala (Kwala) point 14 instead of 45 miles North of Tanga, and thus the latter, which is parallel with the Northern third of Pemba Island, is thrown 25 miles north of it. Wasin Island, between Mombasah and Tanga, is transferred five miles South of the latter. It also omits the ruins of Mtangata. North of this, the ‘Island and Ports of Mombaza’ are remarkably correct, but further North again the Coast, owing to the sickness of the surveyors, was perfunctorily laid down: they seem not to have landed at Makdishu, nor to have sought the debouchure of the Juba river. The late Lieut. Carless, I.N., did not extend his admirable labours beyond Ra’as Hafun. Southward, also, many important places were left unnoticed by Capt. Owen. The Rufiji river is omitted, and the Tanchi inlet (about S. lat. 9° 55′), a little above the mouth of the Lindi river, does not appear upon the chart: it was till lately a nest of slavers, who shared their secret with certain Zanzibar merchants, till unpleasantly disturbed by H. B. Majesty’s ship Grecian. In a return made to the House of Commons from the Hydrographic Department (1848) it was stated that ‘many researches might probably be made from Delagoa Bay to the Red Sea’; I therefore proposed (April 19, 1856) a fresh survey of the Coast, but the project found an obstacle in the Persian War.
