The Indians from abroad arrived at the council-grounds, or the immediate vicinity, two days previous, and one of the most interesting spectacles of the occasion was the entry of the different nations upon the domain and hospitality of the Senecas, on whose grounds the council was to be held. The representation of the Mohawks, coming as they did from Canada, was necessarily small. The Onondagas, with acting Todotahhoh, of the confederacy, and his two counselors, made an exceedingly creditable appearance. Nor was the array of the Tuscaroras, in point of numbers, at least, deficient in attractive and improving features. We called upon and were presented to Black Smith, the most influential and authoritative of the Seneca sachems. He is about sixty years old, is somewhat portly, is easy enough in his manners, and is well disposed, and even kindly towards all who convinced him that they have no sinister designs in coming among his people. Jemmy Johnson is the great high priest of the confederacy. Though now sixty-nine years old, he is yet an erect, fine-looking and energetic Indian, and is hospitable and intelligent. He is in possession of the medal presented by Washington to Red Jacket in 1792, which, among other things of interest, he showed us. It would be imcompatible with the present purpose to describe all the interesting men who were assembled, among whom were Captain Frost, Messrs. Le Fort, Hill, John Jacket, Dr. Wilson and others. We spent much of the time during the week in conversation with the chiefs and most intelligent Indians of the different nations, and gleaned from them much information of the highest interest, in relation to the organization, government, laws, religion and customs of the people and characteristics of the great men of the old and once powerful confederacy. It is a singular fact, that the peculiar government and national characteristics of the Iroquois is a most interesting field of research and inquiry, which has never been very thoroughly, if at all, investigated, although the historic events which marked the proud career of the confederacy have been perseveringly sought and treasured up in the writings of Stone, Schoolcraft, Hosmer, Yates and others. Many of the Indians speak English readily, but with the aid and interpretations of Mr. Ely S. Parker, a young Seneca of no ordinary degree of attainment in both scholarship and general inteligence, and who, with Le Fort, the Onondaga, is well versed in old Iroquois matters, we had no difficulty in conversing with any and all we chose to.
