After retreating a few miles and finding that inactivity and self-restraint meant self-destruction, Du Chaillu took the offensive, and drawing up his men in a favorable position, repelled his pursuers with considerable loss. The wounds from poisoned arrows being external, if subjected to immediate treatment, healed in a few weeks. Further explorations under these circumstances were impossible, for Du Chaillu depended entirely for his success on friendly relations with the natives; in consequence he returned to the sea-coast, and on September 27, 1865, quitted the shores of Western Equatorial Africa. Although the second voyage of Du Chaillu into the unknown regions of Western Equatorial Africa rehabilitated his reputation as a reliable observer, as far as related to geography and natural history, yet his description of the Obongo dwarfs gave rise to further discussion and aspersions. It is needless to say that the discoveries of Stanley in his last African expedition have definitely settled this question in Du Chaillu's favor, and that the studies of Lenz, Marche, and Bastian, in and near the region visited by Du Chaillu, confirm the accuracy of his descriptions. Indeed the Obongos of Ashango Land rise in proportion to undersized negroes when compared with the dwarf queen found by Stanley on the eastern edge of the great equatorial forest, who measures only two feet nine inches in height. Thus in time has come complete vindication of all of Du Chaillu's statements as to the wonders of the Ashira and Ashango Lands, which portions of Western Equatorial Africa he was the first to explore. If the geographical extent of his explorations give way to that of other African travellers, yet it must be admitted that he stands scarcely second to any in the number, importance, and interest of his contributions and collections in connection with ethnography and natural history of Equatorial Africa. In later years Du Chaillu has devoted his attention to the northern parts of Sweden, Norway, Lapland, and Finland, and although his travels in these regions had no important geographical outcome, yet they resulted in lately placing the general public in possession of many interesting details of these countries, as given in his book called "The Land of the Midnight Sun." His important work, "The Viking Age," is an elaborate presentation of his theory that the ancestors of the English-speaking races were Vikings and not Anglo-Saxons, and has awakened much comment in the scientific world. "Ivar the Viking," his latest book, is a popular account of Viking life and manners in the third and fourth centuries. [Illustration: Arrows of the African Pigmies.] XIV.
