ACCORDING to present arrangements, we believe that Mr. Keith Johnston, the leader of the expedition which the Committee of the African Exploration Fund are about to despatch from the East Coast of Africa to Lake Nyassa, will leave England on November 14 for Zanzibar, together with his second in command, Mr. Thomson, whose more especial function it will be to study the geology of the country traversed. Mr. Thomson, we believe, has had an excellent training as a geologist, and it is expected that he will make important contributions to our knowledge of the geology of the region to be visited. The expedition will not actually start for the interior till next spring, and the interval will no doubt be utilised in making short journeys on the mainland, and in procuring all information possible in regard to the inhabitants, language, &c., of the region which is about to be thoroughly and scientifically explored. We sincerely trust that Mr. Johnston may not meet with the same trouble in the matter of porters as has so long retarded the progress of the Belgian and one or two other expeditions, but we do not hear that the Royal Geographical Society have formally given in their adhesion to the most recent suggestion for facilitating African travel by the purchase of one or more Indian elephants.
