defects. If it should be the determina-


 Il ot the State, to appropriate sufficient n to build only one of the above works, the pier must then be first built, as we Can with positive certainty, calculate the good to be derived from such an improvement. It now remains with the authority of the State of Tennessee to decide on this subject. The probable cost of these works, recommended for the improvement of the Suck, here fol- lol 5:

 7He Boiling Poh-This is an obstruction If hat, presents impediments to the navigation ll v &thigh water, and is at it's worst at high f'water mark. The condition of this pass dur ing the dry season of the year, is equal in its advantages to any other part of the river- The flow at low water, is concentrated to a channel of one hundred feet in width, and has depth of from len 10 .ftieen feet with little or no faH. This channel is in the mid ale of the river, on the right and left of which arc many large rocks, which are wholly bare at low 4 ter. The banks of the river are about two hundred yards apart above and below the obstruction, and at the obstruction is less than one hundred yards. It is the want of room for the heavy frcshets to pass through this narI ow neck, and the sudden expansion of the river below it, that causes the fall to increase with the freshets; added to which the large rocks against which the flow ofhigh water for Ces itself, and produces at that depth heavy motion CT breaking of the water, that causes the Boiling Pot, always increasing with the diffi- culty the water finds in passing through this narrow pass, and forcing its way by the rocks above named The fall at the time of survey was two feet two inches, and the high water mark is forty feet. The river at the time of survey was seventeen feet above low water mark, so have only my information as to the character Of the rocks spoken of, from the intelligent gentlemen who accompanied me. The current at this pass does net exceed five and half miles an hour, a current that the ascending boats could well pass were it not for the boiling evidently produced by the rocks that stand in the narrow pass, that are out of the water at the dry season Of the year. By removing these rocks we will give space for the water to pass, and also smooth the bottom over which the freshets flow. It is anticipat- ed tLat the removal of these rocks will smooth the surface of the current, and annul the Boil ing Pot, which does not exceed in length one Hundred and ffy yards. It is recommend cd as a first experiment that these rocks be removed, for which follows the estimate:
 Estimate for he inhrovemcnt of the Boii- ing Pot.-1'he amount of labor necessary to remove the obstructions at this point, consist ing of large detached rocks, will probably cost, say S5,000 % If all the works recommended be
 necessary forth Improvements
 it will require gross sum of S20,0 40 If the wing dam should be adopt
 cd and should suffice without
 the pier, which is quite proba-
 ble, the whole of the improve Q ment will cost only S11,O60 co If the pier should be adopted and
 the wing dams emitted, the
 whole of the improvement will
 cost S12,820 40 l cannot close without expressing my re- gret, that the river did not afford me better opportunity of presenting a more perfect re- port. However, have denc the best that circumstances would permit, believing that have not under estimated the value of making the Improvements.
 All of which is most respectfully submit ted by your most respectful, humble servant,
 J. A. DUMESTE, Engineer. N. B.-A canal is practicable at the Suck, but the cost would far exceed the means that could be at command, and would cost much than i'm, JoJ
