Morgan describes the system of trails used by the Iroquois, but fails to mention bridges and other more permanent structures: 'The principal villages of the Iroquois, in the days of aboriginal dominion, were connected by well-beaten trails. These villages were so situated that the central trail, which started from the Hudson at the site of Albany, passed through those of the Mohawks and Oneidas; and, crossing the Onondaga valley and the Cayuga country, a few miles north of the chief settlements of these nations, it passed through the most prominent villages of the Senecas, in its route to the valley of the Genesee. After crossing this celebrated valley, it proceeded westward to lake Erie, coming out upon it at the mouth of Buffalo creek, on the present site of Buffalo.' §REF§Morgan, Lewis Henry, and Herbert M. Lloyd 1901. “League Of The Ho-De’-No-Sau-Nee Or Iroquois. Vol. Ii”, 80§REF§ 'We have thus followed the great Indian trail, Wä-a-gwen[unknown] -ne-yu, through the State, from the Hudson to lake Erie; noticing, as far as ascertained, the principal stopping-places on the route. To convey an adequate impression of the forest scenery, which then overspread the land, is beyond the power of description. This trail was traced through the over-hanging forest for almost its entire length. In the trail itself, there was nothing particularly remarkable. It was usually from twelve to eighteen inches wide, and deeply worn in the ground; varying in this respect from three to six, and even twelve inches, depending upon the firmness of the soil. The large trees on each side were frequently marked with the hatchet. This well-beaten footpath, which no runner, nor band of warriors could mistake, had doubtless been trodden by successive generations from century to century. It had, without question, been handed down from race to race, as the natural line of travel, geographically considered, between the Hudson and lake Erie. While it is scarcely possible to ascertain a more direct route than the one pursued by this trail, the accuracy with which it was traced from point to point, to save distance, is extremely surprising. It proved, on the survey of the country, to have been so judiciously selected that the turnpike was laid out mainly on the line of this trail, from one extremity of the State to the other. In addition to this, all the larger cities and villages west of the Hudson, with one or two exceptions, have been located upon it. As an independent cause, this forest highway of the Iroquois doubtless determined the establishment of a number of settlements, which have since grown up into cities and villages.' §REF§Morgan, Lewis Henry, and Herbert M. Lloyd 1901. “League Of The Ho-De’-No-Sau-Nee Or Iroquois. Vol. Ii”, 94§REF§ We are unsure about the infrastructural changes brought about by white settlers in the area. | |
