Nowhere, however, can there be found a statement by this historian in which he lays an unequivocal claim to the authorship of the works which have been published under his name. By his own words quoted above he admits that the work was, at least in part, coöperative, and that he was a compiler of the work of his assistants. And for any one man to assert authorship of the Bancroft series of histories would be preposterous. According to actual computation, the mere work of arranging the material and writing the History of the Pacific States, after a small army of note-takers had concluded their operations, represents an equivalent to the labors of one man for a hundred years: (Frances Fuller Victor in _Salt Lake Tribune_, April 14, 1893.) Moreover, the use of quotations from foreign languages, of which Mr. Bancroft had no knowledge, proves that parts of the work are not from his pen, while the different literary styles (see for example, the review of Oregon I in the _New York Tribune_, Nov. 26, 1886; in the _S. F. Argonaut_, Oct. 23, 1886; in the _Sacramento D. Record-Union_, Oct. 27, 1886; and in the _Portland Oregonian_, Oct. 28, 1886), and varying degrees of historical workmanship (Compare reviews of Oregon II in _N. Y. Tribune_, January, 1887; and in _S. F. Chronicle_, Jan. 13, 1887, with reviews of other Bancroft works) clearly reveal the work of a number of writers. A little knowledge on this point has proved a dangerous thing for the reputation of the histories. Some of the newspapers of the coast have learned that Mr. Bancroft did not do all the writing and have even published the names of other authors of the series with statements more or less conjectural as to the writing done by them. In some cases, wild speculations as to the authorship of the works have been published. Many are under the impression that those who went about taking statements of pioneers and in other ways collecting material were themselves writing the manuscript which was published, and that consequently much of the history is no more critically written than an ordinary newspaper article, and as little known about its authorship. Furthermore, it is believed in some quarters that those who prepared narrations for Mr. Bancroft were writing history for him to publish, and that persons not connected with the Bancroft library were authors of parts of the work. In accordance with this idea, it has been claimed that a certain tone favorable to the Mormons which runs through the History of Utah is to be accounted for by the theory that the volume was written by some one connected with the Mormon church, whereas the truth is that, although the historian of that church prepared some data for Mr. Bancroft's use, the work was prepared in the library by Mr. Bancroft and one of his assistants from the annals in his possession (Frances Fuller Victor in _Salt Lake Tribune_, April 14, 1893).
