It is proposed to apply this amount to the removal of wrecks and snags and the improvement of the worst of the bars on these rivers, as far as the appropriation will allow, from their mouths to Columbus, on the Chattahoochee, and to Albany, on the Flint. The original estimates of cost of improving these rivers, as recommended by me in my last annual report, are as follows: Chattachoochee River, Georgia.
