The result of this series of conquests, was, that the Five Nations finally became entitled, or at least laid claim to all the territory not sold to the English, from the mouth of Sorel River, on the south side of lakes Erie and Ontario, on both sides of the Ohio, until it falls into the Mississippi; and on the north side of these lakes, the whole tract between the Outawas River and lake Huron. [FN] The historian, Douglas, estimates their territory at about 1200 miles in length, from north to south, and from 700 to 800 miles in breadth. * * * * * [FN] Smith's History of New-York. The most moderate account of their population we have seen, was published by an agent of Virginia, who held a conference at Albany with the chiefs, in 1677. The warriors were then numbered as follows: Mohawks, 300 Oneidas, 200 Onondagas, 350 Cayugas, 300 Senecas, 1000 ____ Total, 2150 This would make the whole population about 7000. Even so late as the Revolutionary war, the British had in their service, according to the calculation of their own agents: Mohawks, 300 Oneidas, 150 Onondagas, 300 Cayugas, 230 Senecas, 400 To which must be added 200 Tuscaroras--a tribe expelled from North Carolina in 1712, and received by the five Nations, to constitute a sixth member of the Confederacy. We must also add 220 warriors who adhered to the United States. The whole number actually engaged in the contest would then amount to 1800. The Five Nations entered into a treaty of peace with the Dutch soon after their settlement in New-York. They treated with the English subsequently on the same terms; and this memorable engagement remained inviolate for more than a century, during all the revolutions and machinations of the French and English governments, on either side. With the former of these people they were often at war.
