Note 21 — III
Reading edition
Green River, rising in central Kentucky, flows west through the coal fields to its junction with the Big Barren; thence it turns north, and empties into the Ohio nine miles above Evansville, Indiana. Beginning with 1808 the state legislature expended large sums of money for improving navigation on Green River. As a consequence small steamboats may ascend it to a distance of more than a hundred and fifty miles. The length of the stream is estimated at three hundred and fifty miles.—Ed.
