the actual condition of the Ohio, say at the dawning of the eighteenth century. That it was greatly clogged with sunken logs and protruding reefs and bars, of course, goes without saying. Perhaps the average stage of water was less than it is today; and yet the vast amount of water that stood in the tangled forests and open swamps and meadows drained off so slowly as to maintain a more uniform stage of water than is true in our day of alternate flood and drought. If less water flowed in the Ohio's bed a century ago the volume was at least more uniform than it is today.
As early as January 1817 a resolution was passed by the Legislature of Ohio inviting the coöperation of Virginia, Pennsylvania, Kentucky, and Indiana for the improvement of their great waterway. Virginia, Pennsylvania, and Kentucky promptly responded, and in 1819 a preliminary examination was made by General Blackburn of Virginia, General John Adair of Kentucky, General E. W. Tupper of Ohio and Walter Lowrie, Esq. of Pennsylvania who made reports to their several legislatures under the date of November 2, 1819.
