To gratify the moral interest belonging to the subject, by full and elaborate plans and descriptions, would require time and means, very different from any at my command the past season; but the topic was one which admitted of incidental attention, while awaiting decisions and obviating objections which some of the tribes urged to the general principles and policy of the census. And while the subject of a full archæological and ethnological survey of the State is left as the appropriate theme of future research, facts and traditions, bearing on these subjects, were obtained and minuted down, at various points. In availing myself of the liberty extended to me in this particular, by your instructions, I have, in fact, improved every possible means of information. Notes and sketches were taken down from the lips of both white and red men, wherever the matter itself and the trustworthiness of the individual appeared to justify them. Many of the ancient forts, barrows and general places of ancient sepulchre were visited, and of some of them, accurate plans, diagrams or sketches made on the spot, or obtained from other hands. A general interest was manifested in the subject by the citizens of western New-York, wherever it was introduced, and a most ready and obliging disposition evinced, on all hands, to promote the inquiry. The result of these examinations, and collections made by the wayside, it is my intention to report in the form of _Historical and Ethnological Minutes_, which will be engrossed without loss of time from my original notes. These minutes, when properly arranged and copied, will constitute a document supplementary to the report here offered. It is not to be inferred, however, that they will exhibit a compact and full digest of Iroquois history. Attention has rather been given to the lapses in their history, and to the supplying of data for its future construction. Little more has ever been thought of. This part of my investigations will be communicated, therefore, as a contribution to the historical materials of the State, touching its aborigines. Satisfied that the New-York public regard the subject with decided approbation, and well aware of the munificence which has marked the State policy, with regard to the acquisition of historical documents from abroad, I may, I trust, be permitted to indulge the hope, that the Legislature will likewise extend its countenance to this portion of the labor which, as the State Marshal under the act, I have performed.
