The railway leading north from Atlanta to Chattanooga exhibits, throughout the line, relics of Sherman's protracted struggle with the Confederates as he pressed southward, and they opposing him were repeatedly outflanked and retired to new defenses. Long ranges of hills cross the country from northeast to southwest, and on their crests are the remains of massive breastworks and battlements which time is gradually obliterating. Dalton, Resaca and Allatoona were all formidable defensive works, and each in turn was outflanked. Rome, the chief town on this route, now has seven thousand people and various factories. To the westward of Atlanta the railway leads a hundred miles to Anniston, Alabama, in the foothills of the Blue Ridge among the rich beds of Alabama iron-ores, and then to Talladega, the Indian "village on the border," where General Jackson fought one of his severest battles with the Creeks. It is now a busy manufacturing town. Beyond is the great industrial city of Birmingham with thirty-five thousand people, founded in 1871, a phenomenal development of the "New South," its industry being exhibited in enormous iron and steel mills, foundries, and similar establishments. Near the city is its El Dorado, the Red Mountain containing vast stores of hematite iron-ores, with abundant coal and limestone, minerals which have made Alabama the third iron-producing commonwealth in the United States, three-fourths of it being made in the Birmingham district. Nearby is another iron town of recent foundation, Bessemer, and a short distance to the southwest the old Alabama city of Tuscaloosa, the seat of the University of Alabama. This Indian word means the "Black Warrior," and thus was named the river, Tuscaloosa being at the head of steamboat navigation on the Black Warrior. The tradition is that before the white man knew this region it was held by a proud and powerful Indian tribe. When De Soto came along in 1540, searching for gold, he encountered these Indians, whose sachem was the fearless and haughty black giant Tuscaloosa. By stratagem De Soto captured the giant and carried him off a hostage down to Mobile, whence he afterwards escaped. This old city is shown on a French map of Louisiana published in 1720.
