A friend of the author, a highly respectable and intelligent octogenarian, Samuel Woodruff, Esq., of Windsor, Connecticut, made a visit to Brant at the Grand River Settlement, in the summer of 1797, and remained with him several days, in the enjoyment of frequent and full conversations upon many subjects. Mr. Woodruff has obligingly furnished a dozen pages or more of instructive notes and memoranda of those conversations, which have been freely used. The author is likewise under obligations to Professor Marsh of Burlington College, (Vt.) a connexion, by marriage, of the Wheelock family, for several of Brant's original letters; and also to Thomas Morris, Esq., of New-York, who knew the chief well, and was several years in correspondence with him, for the same favour. Mr. Campbell has, moreover, supplied several documents of value, obtained by him after the publication of his own book. Having, by the acquisition of these and other papers, procured all the materials that appeared to remain, or, at least, all that were accessible, while the documentary papers for the first division of the work were yet very incomplete, the author, like Botta, in his promised complete history of Italy, has been compelled to write the latter portion of the work first. In the execution of this task, he had supposed that the bulk of his labour would cease with the close of the war of the Revolution, or at most, that some fifteen or twenty pages, sketching rapidly the latter years of the life of Thayendanegea, would be all that was necessary. Far otherwise was the fact. When the author came to examine the papers of Brant, nearly all of which were connected with his career subsequent to that contest, it was found that his life and actions had been intimately associated with the Indian and Canadian politics of more than twenty years after the treaty of peace; that a succession of Indian Congresses were held by the nations of the great lakes, in all which he was one of the master spirits; that he was directly or indirectly engaged in the wars between the United States and Indians from 1789 to 1795, during which the bloody campaigns of Harmar, St. Clair, and Wayne, took place; and that he acted an important part in the affair of the North-Western posts, so long retained by Great Britain after the treaty of peace. This discovery compelled the writer to enter upon a new and altogether unexpected field of research. Many difficulties were encountered in the composition of this branch of the work, arising from various causes and circumstances. The conflicting relations of the United States, the Indians, and the Canadians, together with the peculiar and sometimes apparently equivocal position in which the Mohawk chief--the subject of the biography--stood in regard to them all; the more than diplomatic caution with which the British officers managed the double game which it suited their policy to play so long; the
