Mr. Bancroft, wrote but two hundred and seventy out of the four thousand pages of the Native Races, devoting his time while that series was in preparation largely to a rewriting of the first volume of Central America, to a continuation of a summary of early voyages for other volumes, and to a perfection of the plan and a collecting of material for the histories. His relation to this work may be likened to that of a managing editor. He decided upon the division of labor as suggested by Oak or others, and required changes in the manuscript as completed if he considered them necessary, either for the sake of treatment or style, but the extent of his writing as printed in this work certainly falls far short of that necessary to substantiate the claim which he has made to its authorship. The chapter which he wrote was that on the Hyperboreans. As to this work, he tells us in the Literary Industries that during the first half of the year 1873 he "was writing on northern Indian matter, giving out the notes on the southern division to go over the field again and take out additional notes": (Lit. Ind. 571). As to his further connection with the work, he says that in December of the same year he became convinced that the plan of treating Indian languages adopted by Goldschmidt was not the proper one, and that the latter was "obliged to go over the entire field again and re-arrange and add to the subject matter before I would attempt the writing of it." (Lit. Ind., 573.) This passage ascribes the actual preparation of the volume to Goldschmidt, and the writing referred to here must have been largely in the nature of editorial work. It is hardly to be presumed that a man of Mr. Bancroft's education and slight literary experience would have attempted at this time anything so ambitious as the complete preparation of a treatise on Indian languages. We see, then, that although the influence of Mr. Bancroft was felt in arrangement and even in style, the Native Races was written almost entirely by other persons. But one would hardly suppose that such was the case from reading the words: "During the progress of this work I succeeded in utilizing the labors of my assistants to the full extent of my anticipations": (Lit. Ind., 304).
