There are/owr of these iron regions, all differing, more or less,in geological and mineral characters, as follows : First, The Eastern. This runs through the State, and lies alongand in front of the Unaka group of mountains. Most of its banksoccur in the coves included in the mountain ridges. Secondly y The '^Dyestone^' Region. This skirts the eastern baseof the Cumberland, and Walden's ridge, from Virginia to Georgia. Itextends out laterally into the Valley of East Tennessee from ten totwenty miles. The Sequatchee and Elk valleys are included. Thirdly y The Cumberland. Associated with the coal measures,on the mountain, in the northern part of the State, — a new develop-ment of the survey. Fourthly, The Western Region, occupying a wide strip of thewestern part of Middle Tennessee, and a portion of the District. Thisextensive field runs from out of Kentucky to the Alabama line. We will notice each of these, so far as our investigations up to thistime will permit, with reference to their extent, ores, banks, and iron-works. We will also add such practical suggestions as may occurto us. We trust the attention of capitalists and iron-masters abroad may becalled to these promising iron-fields of Tennessee.
