Summary

The New International Encyclopædia…

The greater part of the mountain region, occupying more than one-third of the State, belongs to the Alleghany Plateau, though the mountains in the extreme southern section may be considered as a northern extension of the Cumberland Plateau. The mountains of the northeast are chiefly in the form of parallel ridges with a southwest and northeast trend, but the southern part of the plateau is irregularly dissected by river valleys, presenting broad domes with spurs running in all directions, and but few definite ridges.

The closely allied foundry and machine shop industry has had a rapid recent growth, in the manufacture of coke the State ranks second, and the Flat Top district, in the southern part of the State, is the second most important coking region in the United States. The availability of natural gas has led to a thriving glass-manufacturing industry. There was a significant development between 1890 and 1900 in the manufacture of pottery, terra-cotta, and fire-clay products in the region adjacent to East Liverpool, Ohio.
