The Oswego is formed by the junction of the Oneida and the Onondaga, both of which flow from lakes; and it pursues its way, through a gently undulating country, some eight or ten miles, until it reaches the margin of a sort of natural terrace, down which it tumbles some ten or fifteen feet, to another level, across which it glides with the silent, stealthy progress of deep water, until it throws its tribute into the broad receptacle of the Ontario.〔James Fenimore Cooper, (''The Pathfinder'' ), Chapter 3〕
