Wheeling (Va.), August 19th, 1843.

I have just accomplished the passage of the Alleghany mountains, in the direction from Baltimore to this place, and must say, that aside from the necessary fatigue of night riding, the pass from the Cumberland mountains and Laurel Hill is one of the easiest and most free from danger of any known to me in this vast range. An excellent railroad now extends from Baltimore, by Frederick and Harper's Ferry, up the Potomac valley and its north branch quite to Cumberland, which is seated just under the mountains, whose peaks would seem to bar all farther approach. The national road finds its way, however, through a gorge, and winds about where "Alps on Alps arise," till the whole vast and broad-backed elevation is passed, and we descend west, over a smooth, well constructed macadamized road, with a velocity which is some compensation for the toil of winding our way up. Uniontown is the first principal place west. The Monongahela is crossed at Brownsville, some forty miles above Pittsburgh, whence the road, which is every where well made and secured with fine stone bridges, culverts and viaducts, winds around a succession of most enchanting hills, till it enters a valley, winds up a few more hills, and brings the travellers out, on the banks of the Ohio, at this town.

The entire distance from the head of the Chesapeake to the waters of the Ohio is not essentially different from three hundred miles. We were less than two days in passing it, twenty-six hours of which, part night and part day, were spent in post-coaches between Cumberland and this place. Harper's Ferry is an impressive scene, but less so than it would be to a tourist who had not his fancy excited by injudicious descriptions. To me, the romance was quite taken away by driving into it with a tremendous clattering power of steam. The geological structure of this section of country, from water to water, is not without an impressive lesson. In rising from the Chesapeake waters the stratified rocks are lifted up, pointing west, or towards the Alleghanies, and after crossing the summit they point east, or directly contrary, like the two sides of the roof of a house, and leave the inevitable conclusion that the Alleghanies have been lifted up by a lateral rent, as it were, at the relative point of the ridge pole. It is in this way that the granites and their congeners have been raised up into their present elevations.

I did not see any evidence of that wave-like or undulatory structure, which was brought forward as a theory last year, in an able paper forwarded by Professor Rogers, and read at the meeting of the British Association for the Advancement of Science at Manchester. No organic remains are, of course, visible, in this particular section, at least until we strike the coal and iron-stone formation of Pittsburgh. But I have been renewedly impressed with the opinion, so very opposite to the present geological theory, that less than seven thousand years is sufficient, on scientific principles, to account for all the phenomena of fossil plants, shells, bones and organic remains, as well as the displacements, disruptions, subsidences and rising of strata, and other evidences of extensive physical changes and disturbances on the earth's surface. And I hope to live to see some American geologist build up a theory on just philosophical and scientific principles, which shall bear the test of truth.

But you will, perhaps, be ready to think that I have felt more interest in the impressions of plants in stone, than is to be found in the field of waving corn before the eye. I have, however, by no means neglected the latter; and can assure you that the crops of corn, wheat and other grains, throughout Maryland, Pennsylvania and Western Virginia, are excellent. Even the highest valleys in the Alleghanies are covered with crops of corn, or fields of stacked wheat and other grains. Generally, the soil west of the mountains is more fertile. The influence of the great western limestones, as one of its original materials, and of the oxide of iron, is clearly denoted in heavier and more thrifty cornfields along the Monongahela and Ohio valleys.

Of the Ohio River itself, one who had seen it in its full flow, in April and May, would hardly recognize it now. Shrunk in a volume far below its noble banks, with long spits of sand and gravel running almost across it, and level sandy margins, once covered by water, where armies might now manœuvre, it is but the skeleton of itself. Steamboats of a hundred tons burden now scarcely creep along its channel, which would form cockboats for the floating palaces to be seen here in the days of its vernal and autumnal glory.

Truly yours,

HENRY R. COLCRAFT
