of the foremost modern physicists, chemists, and other scientific specialists regarding the value of science, not only as knowledge for guidance of life, but as affording the best mental discipline. Mr. Youmans's contributions to the volume were on "Scientific Study of Human Nature" and on "Mental Discipline in Education." Not only as author and lecturer did Mr. Youmans do much for the diffusion of science in America, but also by causing the republication in New York of the most valuable English scientific works as they appeared in London. On his advice Messrs. D. Appleton & Co. produced American editions of Bagehot, Buckle, Carpenter, Darwin, Huxley, Lubbock. Lyell, Roscoe, Spencer, Tyndall, Whewell, and others. In every case the author was paid exactly as much as if he were an American enjoying copyright. In 1871 Mr. Youmans gave further extension to this enterprise by planning the "International Scientific Series," the volumes to appear simultaneously in New York, London, Paris, Leipsic, Milan, and St. Petersburg. The project gave all the ZANZIBAR, a nonarchy on the eastern coast of Africa. The reigning sovereign is Seyid Burgash ben Said, who succeeded his brother in 1870. The area of the sultanate is 23,960 square kilometres. The island of Zanzibar contains about 200,000 inhabitants. The population of the continental possessions of the Sultan is not known. His annual revenue is about $1,250,000, derived chiefly from customs duties, which are regulated by a treaty of commerce concluded with Germany on Aug. 19, 1886. The principal products are cloves, gum-copal and other gums, red pepper, and cocoanuts. The transit trade in elephants' tusks amounts to $1,500,000 per annum. Anglo-German Agreement. The Sultan of Zanzibar formerly held dominion over the island only. He acquired and garrisoned points on the mainland for the purpose of keeping open and guarding trade-routes into the interior. Under compulsion from England he suppressed the slave-trade. His continental possessions were not defined, and, when the German East African Company acquired territory in the region, disputes arose. In 1886 a joint commission, representing Great Britain, Germany, and France, fixed the boundaries of his dominions, and England and Germany entered into an agreement as to their respective spheres of influence. The work of the commission was embodied in a formal agreement effect of international copyright to the authors concerned. By judicious selection of eminent specialists in whatever land they were to be found, the whole civilized world had popular expositions of interesting scientific topics from the most competent sources rendered into the reader's own tongue. In 1872 Mr. Youmans was appointed editor of "The Popular Science Monthly," a magazine established, at his suggestion, by the Messrs. Appleton. Its purpose was to present the constant advances of science in all departments, and to discuss the larger relations of science to history, education, the state, and the problems of life. His editorials on current topics were crisp, forcible, and characteristic, often widely quoted, and sometimes combated, and served to maintain his influence as an educator. In the winter of 1880-'81 he was attacked by pneumonia, and his constitution, early impaired by lack of exercise through blindness, never recovered. He married in 1861 the widow of William L. Lee, who survives him. by Germany to recognize the sovereign rights of the Sultan over Zanzibar and Pemba, with adjacent islands, Lamu, Mafia, and a strip of coast of 10 nautical miles' breadth extending from the mouth of the Miningani River in the Bay of Tunghi as far as Kipini. North of Kipini the Sultan has the stations Kismaju, Barawa, Merka, and Makdishu, each with a radius of 12 nautical miles, and Warsheik with 5 nautical miles of territory. Great Britain agreed to use her influence to induce the Sultan to allow the Germans to have possession of the ports of Dar-es-Salaam and Pangani, paying over the customs receipts to the Sultan; also to promote a friendly agreement with Germany in regard to conflicting claims to districts in the Kilimandjaro mountains. The authority of the Sultan of Vitu, who stands under German protection, was recognized over a strip of coast including Manda Bay. The sphere of influence of England and Germany in the region lying between the Rovuma and Tana rivers is divided by a line beginning at the mouth of the river Wanga or Umbe, running to Lake Jipe, then along its eastern and northern banks, across the river Lumi, so as to bisect the districts of Taveta and Dshagga, and then along the northern slope of the Kilimandjaro mountain to a point on the eastern bank of the Victoria Nyanza, where it is intersected by the first parallel of south latitude.
