The creek descends to the north-west, and on entering theflats, its velocity slackens, and it becomes discolored, by the oozings of themarsh. Before it reaches the lake, it is reinforced by the waters of LittleBuffalo Creek, entering it from the north-east. The approach of BuffaloCreek to the lake is at an acute angle, the course of the stream being nearlynorth. The junction takes place near the middle of the western line of the^ • city, as may be seen upon the map. The deep and narrow estuary of this stream constitutes the harbor of BuSalo.
