TANG A BAY. 



Tanga Bay is placed by Captain Owen in S. 

 lat. 4"^ 35', or five miles N. of Wasin Island, and 

 thus the positions of the whole Coast are throw^n 

 out.^ It is in S. lat. 5"^; South of Wasin, and be- 

 tween that place and the mouth of the Panga-ni 

 river. This extraordinary error can have been 

 made only by a confusion of the survey-sheets, and 

 it appears the more singular in a work of such 

 correctness. The inlet, called probably from its 



1 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 Tauga, 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 sick- 

 ness of the surveyors, was perfunctorily laid down : they seem 

 not to have landed at Makdishu, nor to have sought the debou- 

 chure of the Juba river. The late Lieut. Carless, I.N., did 

 not extend his admirable labours beyond Ea'as Hafun. South- 

 ward, also, many important places were left unnoticed by Capt. 

 Owen. The Eufiji 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 Hydro- 

 graphic Department (1848) it was stated that ' many researches 

 might probably be made from Delagoa Bay to the Eed Sea ' ; 

 I therefore proposed (April 19, 1856) a fresh survey of the 

 Coast, but the project found an obstacle in the Persian War.
