Appendix No. 13. Creosoting on New Orleans and Mobile Railroad
The line of railroad between New Orleans and Mobile runs parallel to and near the coast, crossing various arms of the sea, and so near the mouths of rivers that the tide ebbs and flows a considerable distance above the railroad crossings. The salt water flows over the bar at high tide, and at the ebb the fresh water, being lightest, flows over the top, leaving a basin of salt water in which the teredo navalis finds some of his choicest feeding grounds. As the tidal rise is only a foot or two, the tidal currents are not very strong. It often happens that piles driven for these bridges will be honeycombed from five to forty feet below the surface of the water, while not a sign of the teredo can be found at the surface.
