This life-boat, after being set up with some difficulty at Zanzibar, accompanied us on our trip northwards. The galvanized and corrugated iron, in longitudial furrows, like the roofing of railway stations, but only sixpence-thick, proved far superior to the softer copper formerly used. The Arabs, who could not sufficiently admire her graceful form, the facility with which she was handled, and above all things, her speed, called her the Sharrádeh, or runaway (mare). The ‘Louisa’ was indeed sadly given to breaking her halter and to bolting. We lost her during a storm near Mombasah, but an article so remarkable and so useless to any but ourselves was of course easily recovered. Compelled by want of carriage on the coast to reduce my material, I left her most unwillingly at Zanzibar. Buoyant as graceful, fireproof, wormproof, and waterproof, incapable of becoming nail-sick or water-logged, she would indeed have been a Godsend upon the Tanganyika lake, sparing us long delay, great expense, and a host of difficulties and hardships. ----- Footnote 123: This salt stream might have been some confusion with the salt Lake Naivasha or Balibali, in about S. lat. 1° 40′, first laid down by the Rev. Thomas Wakefield, ‘Routes of Native Caravans from the Coast to the Interior of Eastern Africa, chiefly from information given by Sádi bin Ahédi, a native of a district near Gázi (Gási?), in Udigo, a little north of Zanzibar’ (pp. 303-339, Journal of the Royal Geographical Society, vol. xl. 1870). Of this very valuable paper I shall have more to say in Vol. II. Footnote 124: I leave these words as they were written in 1857, a time when German nationality did not exist, and when the name of German had perhaps reached its lowest appreciation. Throughout the history of the nineteenth century there is nothing more striking than the change which the last decade has worked in Europe, than the rise of the mighty power, which in a month crushed the armies of France, and which tore from her side the provinces of Alsace and Lorraine. By an Englishman who loves his country, nothing can be more enthusiastically welcomed than this accession to power of a kindred people, connected with us by language, by religion, and by all the ties which bind nation to nation. It proves that the North is still the fecund mother of heroes, and it justifies us in hoping that our Anglo-Teutonic blood, with its Scandinavian ‘baptism,’ will gain new strength by the example, and will apply itself to rival our Continental cousins in the course of progress, and in the mighty struggle for national life and prosperity. Footnote 125: Dr Ruschenberger remarked the skeletons on the beach to the North and to the East of the Island. APPENDIX. THE UKARA OR UKEREWE LAKE. A DEDUCTION FROM THE REV. MR WAKEFIELD’S ‘ROUTES.’
