new arrangements of lines of travel and transportation will develop the magnificent mineral deposits of this region and present special attractions for mining enterprise. The coals of this region are purer and more available for all kinds of manufacture than in any other part of the Alleghany coal-field. The seams of coal are also thicker and more numerous and can be more cheaply mined. Charleston is 200 miles nearer Cincinnati and the western ports than Pittsburg. With energetic exertion it may yet become the metropolis of this mining region.

The productive coal fields of Ohio embrace about 12,000 square miles. The coal measures, however, including the carboniferous limestone, cover fully onethird of the State. The strata generally dip towards the Ohio river, and the smaller streams follow their inclinations with considerable exactness. The coal seams here are identified with those lying opposite in Pennsylvania, West Virginia, and Kentucky. The coal area of the latter State appears to be but little understood. It runs through some twenty of the eastern counties. The deposits, in position and character, are clearly assimilated to those of West Virginia and Pennsylvania. The coal measures in Tennessee are limited in area, occupying the high mountain plateaus which terminate abruptly on the east, above the escarpments of the Cumberland mountains. Being thus inaccessible, these deposits must, for purposes of fuel, remain for some time undeveloped. Chattanooga, and a few points in Georgia, are favored with copious and accessible supplies of coal in close association with iron. In Alabama the Alleghany coal-field widens out into a basin covering 4,300 square miles, with an unmistakable depression of the entire geologic series southeast from Lookout and Sand mountains. The thinning out of the palæozoic strata westward is very observable. Large deposits of iron surround this coal-field, mostly hematites, especially rich to the eastward. The production of the Alleghany coal-field in 1864 is represented in the following table :

9, 078, 708 The northern coal-field, embracing about 13,000 square miles, lies wholly within the lower peninsula of Michigan. Its coal seams are fewer and thinner than in the Ohio coal measures. But little has been done for its development, its annual product not much exceeding 100,000 tons.

The great central coal-field occupies an area of 50,000 square miles in Indiana, Illinois, and Kentucky. Its extreme length is 350 miles, with a breadth varying from 150 to 200 miles. The palæ zoic column, which in Pennsylvania exceeds a height of five miles, in Illinois is but 3,300 feet high, the coal measures being about 900 feet thick. The maximum depth of the coal measures increases in Indiana, and especially in Kentucky, where the basins are the deepest. The produce of the central coal-field in 1864 was as follows:

Tons. Illinois

1,000,000 Indiana

500, 000 Western Kentucky...

250,000

Total ....

.. 1,750,000 * The commissioner of statistics of the State of Ohio estimates the quantity at double this amount.

The western coal-field in Missouri and Iowa is, properly, a continuation of the great central. It occupies an area of 45,000 square miles, of which 21,000 are in Missouri and 24,000 in Iowa. The geology of Missouri resembles that of Illinois, but the coal measures are not so thick by 150 feet, thinning out rapidly towards the northern edge of this coal field in Iowa, where they are but 100 feet thick, with workable beds of only 4 or 5 fe t. Its product in 1864 was about 500,000 tons. The coals of Arkansas and Nebraska are but the thin western edges of the great western coal-field, as yet but partially developed. All of these coal-fields are parts of the Appalachian coal, or Mississippi system, embracing a total area of 190,000 square miles, from which were mined in 1864 a total of 11,428,708 tons. The Mississippi basin, embracing an area of 1,500,000 square miles, is eminently available, in all its wondrous agricultural and mineral resources, to the demands of industry and commerce. Its territorial configuration, with its matchless system of internal navigation, is unrivalled in all the requisites for the seat of a mighty civilization. Its entire area can be as densely populated as England, with greater facilities for the support of animal life.

The New England coals are anthracite in character, but thin and irregular in stratification, continually interrupted by faults, dikes, troubles, &c. This coalfield occupies its true palæological position in our American system, but its accompanying sedimentary strata have been largely metamorphosed by heat into the sub-crystalline. The basins are very irregular, indicating a degree of dislocating volcanic action highly unfavorable to even and uniform stratification during the period of coal deposit. Subsequent lateral contractions, doubling the strata in sharp waves, have also caused the entire coal series to slide above or below their true geological position. The immense thickness of the palæozoic formations in Pennsylvania doubtless protected the wonderful coal deposits of the State from the same destructive movements, and perhaps added materially to their growth by supplying the necessary carbon and bitumen. Mining for coal does not at present offer any inviting prospects to remuneration in New England.

The Arcadian coal-field in British North America embraces a workable area of 2,200 square miles, divided into several basins and sub-basins. The amount of sulphur and iron pyrites in the measures and seams of this coal-field are a serious injury to the coal, which is of a rich and highly bituminous character, indicating remoteness from the great beat which produced the Pennsylvania anthracites. The coal seams are of moderate thickness.

In Eastern Virginia and the Carolinas there are five distinct coal formations. These deposits compared with the great fields of the west are small, but being located in populous districts, have a very considerable local value for fuel and the generation of steam.

The Richmond coal-field, though lying within the granite basins of the primitive formations, is yet the latest deposit. Much injury has been done in parts of this field by the small pits sunk along the outcroppings, which being filled with water, are dangerous to approach from deeper excavations. The Piedmont coal-field, further inland, lies within the gneissic or crystalline sedimentary deposits of the metamorphic era. Its area is small and excessively undulating; its seams range from six to thirty inches. In some localities near the gneiss rock the coal changes to impure anthracite. It is valuable only for domestic purposes. Dan river and Deep river coal-fields are unimportant basins assimilated to the Piedmont. The New river deposit is perhaps the oldest coal in existence, the creation of the proto-carboniferous ages. These coals, however, are only available for domestic use. The surrounding country is rich and promises great commercial and industrial activity.

The coal deposits of the Pacific slope are as yet imperfectly developed. Their area, so far as ascertained, is about equal to the coal-field of Great Britain, or over 6,000 square miles.

Nearly ten years ago it was estimated by high scientific authority that the coal annually employed in England in propelling inachinery generated a productive force equal to the labor of 66,000,000 men, and that if the entire coal pr duct had been so employed, this aggregate would have swelled to 400,000,000. The London Times estimates the mechanical steam power of England at double the muscular force of the entire human race. Reducing this estimate one-half, and applying the same ratio to our resources, what limits shall we assign to American dynamic industrial power, remembering that our coal area is thirtythree times greater than that of England, and of at least equal average value ? The problem transcends ordinary speculation. It grows with our advances in economic science and art, and with each day's experience in the working of those resources. Even the agricultural advantages of soil, climate, and territorial configuration do not promise to surpass the majestic results of the mineral industry of the Union when once the hand of intelligent enterprise shall unlock the stores of subterranean wealth. The wonderful production of the precious metals must be enormously enhanced in order to afford adequate expression of the values soon to be produced by the development of the useful minerals of this republic.
