According to information supplied by Mr Thomas Robinson, an expert engineering authority familiar with the lower Chattahoochee, there was formerly a large mound, now almost entirely washed away, on the eastern bank of the river, about nine miles below Columbus, while on the western or Alabama bank, a mile or two farther down, there is still to be seen another of nearly equal size. "At extreme freshets both of these mounds were partly submerged. To the east of the former, known as the Indian mound, the flood plain is a mile or two wide, and along the eastern side of the plain stretches a series of swamps or wooded sloughs, indicating an old river bed. All the plain between the present river and the sloughs is river-made land. The river bluff along by the mound on the Georgia side is from twenty to thirty feet above the present low-water surface of the stream. About a mile above the mound are the remains of what was known as Jennies island. At ordinary stages of the river no island is there. The eastern channel was blocked by government works some years ago, and the whole is filled up and now used as a cornfield. The island remains can be traced now, I think, for a length of half a mile, with a possible extreme width of 300 feet.... This whole country, on both sides of the river, is full of Indian lore. I have mentioned both mounds simply to indicate that this portion of the river was an Indian locality, and have also stated the facts about the remains of Jennies island in order to give a possible clew to a professional who might study the ground."--Letter, April 22, 1900.
