Virginia is bounded on the east by the Atlantic; on the north by a line of latitude crossing the eastern shore through Watkin's Point, being about 37° 57' north latitude; from thence by a straight line to Cinquac, near the mouth of Potomac; thence by the Potomac, which is common to Virginia and Maryland, to the first fountain of its northern branch; thence by a meridian line, passing through that fountain till it intersects a line running east and west, in latitude 39° 43' 42.4" which divides Maryland from Pennsylvania, and which was marked by Messrs. Mason and Dixon; thence by that line, and a continuation of it westwardly to the completion of five degrees of longitude from the eastern boundary of Pennsylvania, in the same latitude, and thence by a meridian line to the Ohio; on the west by the Ohio and Mississippi, to latitude 36° 30' north, and on the south by the line of latitude last mentioned. By admeasurements through nearly the whole of this last line, and supplying the unmeasured parts from good data, the Atlantic and Mississippi are found in this latitude to be seven hundred and fifty-eight miles distant, equal to 30° 38' of longitude, reckoning fifty-five miles and three thousand one hundred and forty-four feet to the degree. This being our comprehension of longitude, that of our latitude, taken between this and Mason and Dixon's line, is 3° 13' 42.4" equal to two hundred and twenty-three and one-third miles, supposing a degree of a great circle to be sixty-nine miles, eight hundred and sixty-four feet, as computed by Cassini. These boundaries include an area somewhat triangular of one hundred and twenty-one thousand five hundred and twenty-five square miles, whereof seventy-nine thousand six hundred and fifty lie westward of the Alleghany mountains, and fifty-seven thousand and thirty-four westward of the meridian of the mouth of the Great Kanhaway. This State is therefore one-third larger than the islands of Great Britain and Ireland, which are reckoned at eighty-eight thousand three hundred and fifty-seven square miles.
These limits result from, 1. The ancient charters from the crown of England. 2. The grant of Maryland to the Lord Baltimore, and the subsequent determinations of the British court as to the extent of that grant. 3. The grant of Pennsylvania to William Penn, and a compact between the general assemblies of the commonwealths of Virginia and Pennsylvania as to the extent of that grant. 4. The grant of Carolina, and actual location of its northern boundary, by consent of both parties. 5. The treaty of Paris of 1763. 6. The confirmation of the charters of the neighboring States by the convention of Virginia at the time of constituting their commonwealth. 7. The cession made by Virginia to Congress of all the lands to which they had title on the north side of the Ohio.
An inspection of a map of Virginia, will give a better idea of the geography of its rivers, than any description in writing. Their navigation may be imperfectly noted.
Roanoke, so far as it lies within the State, is nowhere navigable but for canoes, or light batteaux; and even for these in such detached parcels as to have prevented the inhabitants from availing themselves of it at all.
James River, and its waters, afford navigation as follows:
The whole of Elizabeth River, the lowest of those which run into James River, is a harbor, and would contain upwards of three hundred ships. The channel is from one hundred and fifty to two hundred fathoms wide, and at common flood tide affords eighteen feet water to Norfolk. The Stafford, a sixty gun ship, went there, lightening herself to cross the bar at Sowel's Point. The Fier Rodrigue, pierced for sixty-four guns, and carrying fifty, went there without lightening. Craney Island, at the mouth of this river, commands its channel tolerably well.
Nansemond River is navigable to Sleepy Hole for vessels of two hundred and fifty tons; to Suffolk for those of one hundred tons; and to Milner's for those of twenty-five.
Pagan Creek affords eight or ten feet water to Smithfield, which admits vessels of twenty tons.
Chickahominy has at its mouth a bar, on which is only twelve feet water at common flood tide. Vessels passing that, may go eight miles up the river; those of ten feet draught may go four miles further, and those of six tons burden twenty miles further.
Appomattox may be navigated as far as Broadways, by any vessel which has crossed Harrison's bar in James River; it keeps eight or ten feet water a mile or two higher up to Fisher's bar, and four feet on that and upwards to Petersburg, where all navigation ceases.
James River itself affords a harbor for vessels of any size in Hampton Road, but not in safety through the whole winter; and there is navigable water for them as far as Mulberry Island. A forty gun ship goes to Jamestown, and, lightening herself, may pass Harrison's bar; on which there is only fifteen feet water. Vessels of two hundred and fifty tons may go to Warwick; those of one hundred and twenty-five go to Rocket's, a mile below Richmond; from thence is about seven feet water to Richmond; and about the centre of the town, four feet and a half, where the navigation is interrupted by falls, which in a course of six miles, descend about eighty-eight feet perpendicular; above these it is resumed in canoes and batteaux, and is prosecuted safely and advantageously to within ten miles of the Blue Ridge; and even through the Blue Ridge a ton weight has been brought; and the expense would not be great, when compared with its object, to open a tolerable navigation up Jackson's river and Carpenter's creek, to within twenty-five miles of Howard's creek of Green Briar, both of which have then water enough to float vessels into the Great Kanhaway. In some future state of population I think it possible that its navigation may also be made to interlock with that of the Potomac, and through that to communicate by a short portage with the Ohio. It is to be noted that this river is called in the maps James River, only to its confluence with the Rivanna; thence to the Blue Ridge it is called the Fluvanna; and thence to its source Jackson's river. But in common speech, it is called James River to its source.
The Rivanna, a branch of James River, is navigable for canoes and batteaux to its intersection with the South-West mountains, which is about twenty-two miles; and may easily be opened to navigation through these mountains to its fork above Charlottesville.
York River, at Yorktown, affords the best harbor in the State for vessels of the largest size. The river there narrows to the width of a mile, and is contained within very high banks, close under which vessels may ride. It holds four fathom water at high tide for twenty-five miles above York to the mouth of Poropotank, where the river is a mile and a half wide, and the channel only seventy-five fathom, and passing under a high bank. At the confluence of Pamunkey and Mattapony, it is reduced to three fathom depth, which continues up Pamunkey to Cumberland, where the width is one hundred yards, and up Mattapony to within two miles of Frazier's ferry, where it becomes two and a half fathom deep, and holds that about five miles. Pamunkey is then capable of navigation for loaded flats to Brockman's bridge, fifty miles above Hanover town, and Mattapony to Downer's bridge, seventy miles above its mouth.
Piankatank, the little rivers making out of Mobjack Bay and those of the eastern shore, receive only very small vessels, and these can but enter them.
Rappahannock affords four fathom water to Hobb's hole, and two fathom from thence to Fredericksburg.
Potomac is seven and a half miles wide at the mouth; four and a half at Nomony bay; three at Aquia; one and a half at Hallowing point; one and a quarter at Alexandria. Its soundings are seven fathom at the mouth; five at St. George's island; four and a half at Lower Matchodic; three at Swan's point, and thence up to Alexandria; thence ten feet water to the falls, which are thirteen miles above Alexandria. These falls are fifteen miles in length, and of very great descent, and the navigation above them for batteaux and canoes is so much interrupted as to be little used. It is, however, used in a small degree up the Cohongoronta branch as far as fort Cumberland, which was at the mouth of Willis's creek; and is capable, at no great expense, of being rendered very practicable. The Shenandoah branch interlocks with James river about the Blue Ridge, and may perhaps in future be opened.
The Mississippi will be one of the principal channels of future commerce for the country westward of the Alleghany. From the mouth of this river to where it receives the Ohio, is one thousand miles by water, but only five hundred by land, passing through the Chickasaw country. From the mouth of the Ohio to that of the Missouri, is two hundred and thirty miles by water, and one hundred and forty by land, from thence to the mouth of the Illinois river, is about twenty-five miles. The Mississippi, below the mouth of the Missouri, is always muddy, and abounding with sand bars, which frequently change their places. However, it carries fifteen feet water to the mouth of the Ohio, to which place it is from one and a half to two miles wide, and thence to Kaskaskia from one mile to a mile and a quarter wide. Its current is so rapid, that it never can be stemmed by the force of the wind alone, acting on sails. Any vessel, however, navigated with oars, may come up at any time, and receive much aid from the wind. A batteau passes from the mouth of Ohio to the mouth of Mississippi in three weeks, and is from two to three months getting up again. During its floods, which are periodical as those of the Nile, the largest vessels may pass down it, if their steerage can be insured. These floods begin in April, and the river returns into its banks early in August. The inundation extends further on the western than eastern side, covering the lands in some places for fifty miles from its banks. Above the mouth of the Missouri it becomes much such a river as the Ohio, like it clear and gentle in its current, not quite so wide, the period of its floods nearly the same, but not rising to so great a height. The streets of the village at Cohoes are not more than ten feet above the ordinary level of the water, and yet were never overflowed. Its bed deepens every year. Cohoes, in the memory of many people now living, was insulated by every flood of the river. What was the eastern channel has now become a lake, nine miles in length and one in width, into which the river at this day never flows. This river yields turtle of a peculiar kind, perch, trout, gar, pike, mullets, herrings, carp, spatula-fish of fifty pounds weight, cat-fish of one hundred pounds weight, buffalo fish, and sturgeon. Aligators or crocodiles have been seen as high up as the Acansas. It also abounds in herons, cranes, ducks, brant, geese, and swans. Its passage is commanded by a fort established by this State, five miles below the mouth of the Ohio, and ten miles above the Carolina boundary.
The Missouri, since the treaty of Paris, the Illinois and northern branches of the Ohio, since the cession to Congress, are no longer within our limits. Yet having been so heretofore, and still opening to us channels of extensive communication with the western and north-western country, they shall be noted in their order.
The Missouri is, in fact, the principal river, contributing more to the common stream than does the Mississippi, even after its junction with the Illinois. It is remarkably cold, muddy, and rapid. Its overflowings are considerable. They happen during the months of June and July. Their commencement being so much later than those of the Mississippi, would induce a belief that the sources of the Missouri are northward of those of the Mississippi, unless we suppose that the cold increases again with the ascent of the land from the Mississippi westwardly. That this ascent is great, is proved by the rapidity of the river. Six miles above the mouth, it is brought within the compass of a quarter of a mile's width; yet the Spanish merchants at Pancore, or St. Louis, say they go two thousand miles up it. It heads far westward of the Rio Norte, or North River. There is, in the villages of Kaskaskia, Cohoes, and St. Vincennes, no inconsiderable quantity of plate, said to have been plundered during the last war by the Indians from the churches and private houses of Santa Fé, on the North river, and brought to the villages for sale. From the mouth of the Ohio to Santa Fé are forty days journey, or about one thousand miles. What is the shortest distance between the navigable waters of the Missouri, and those of the North river, or how far this is navigable above Santa Fé, I could never learn. From Santa Fé to its mouth in the Gulf of Mexico is about twelve hundred miles. The road from New Orleans to Mexico crosses this river at the post of Rio Norte, eight hundred miles below Santa Fé, and from this post to New Orleans is about twelve hundred miles; thus making two thousand miles between Santa Fé and New Orleans, passing down the North river, Red river, and Mississippi; whereas it is two thousand two hundred and thirty through the Missouri and Mississippi. From the same post of Rio Norte, passing near the mines of La Sierra and Laiguana, which are between the North river, and the river Salina to Sartilla, is three hundred and seventy-five miles, and from thence, passing the mines of Charcas, Zaccatecas, and Potosi, to the city of Mexico, is three hundred and seventy-five miles; in all, one thousand five hundred and fifty miles from Santa Fé to the city of Mexico. From New Orleans to the city of Mexico is about one thousand nine hundred and fifty miles; the roads after setting out from the Red river, near Natchitoches, keeping generally parallel with the coast, and about two hundred miles from it, till it enters the city of Mexico.
The Illinois is a fine river, clear, gentle, and without rapids; insomuch that it is navigable for batteaux to its source. From thence is a portage of two miles only to the Chicago, which affords a batteau navigation of sixteen miles to its entrance into lake Michigan. The Illinois, about ten miles above its mouth, is three hundred yards wide.
The Kaskaskia is one hundred yards wide at its entrance into the Mississippi, and preserves that breadth to the Buffalo plains, seventy miles above. So far, also, it is navigable for loaded batteaux, and perhaps much further. It is not rapid.
The Ohio is the most beautiful river on earth. Its current gentle, waters clear, and bosom smooth and unbroken by rocks and rapids, a single instance only excepted.
It is one-quarter of a mile wide at Fort Pitt, five hundred yards at the mouth of the Great Kanhaway, one mile and twenty-five poles at Louisville, one-quarter of a mile on the rapids three or four miles below Louisville, half a mile where the low country begins, which is twenty miles above Green river, a mile and a quarter at the receipt of the Tennessee, and a mile wide at the mouth.
Its length, as measured according to its meanders by Captain Hutchins, is as follows:—

In common winter and spring tides it affords fifteen feet water to Louisville, ten feet to Le Tarte's rapids, forty miles above the mouth of the great Kanhaway, and a sufficiency at all times for light batteaux and canoes to Fort Pitt. The rapids are in latitude 38° 8'. The inundations of this river begin about the last of March, and subside in July. During these, a first-rate man-of-war may be carried from Louisville to New Orleans, if the sudden turns of the river and the strength of its current will admit a safe steerage. The rapids at Louisville descend about thirty feet in a length of a mile and a half. The bed of the river there is a solid rock, and is divided by an island into two branches, the southern of which is about two hundred yards wide, and is dry four months in the year. The bed of the northern branch is worn into channels by the constant course of the water, and attrition of the pebble stones carried on with that, so as to be passable for batteaux through the greater part of the year. Yet it is thought that the southern arm may be the most easily opened for constant navigation. The rise of the waters in these rapids does not exceed ten or twelve feet. A part of this island is so high as to have been never overflowed, and to command the settlement at Louisville, which is opposite to it. The fort, however, is situated at the head of the falls. The ground on the south side rises very gradually.
The Tennessee, Cherokee, or Hogohege river, is six hundred yards wide at its mouth, a quarter of a mile at the mouth of Holston, and two hundred yards at Chotee, which is twenty miles above Holston, and three hundred miles above the mouth of the Tennessee. This river crosses the southern boundary of Virginia, fifty-eight miles from the Mississippi. Its current is moderate. It is navigable for loaded boats of any burden to the Muscle shoals, where the river passes through the Cumberland mountain. These shoals are six or eight miles long, passable downwards for loaded canoes, but not upwards, unless there be a swell in the river. Above these the navigation for loaded canoes and batteaux continues to the Long island. This river has its inundations also. Above the Chickamogga towns is a whirlpool called the Sucking-pot, which takes in trunks of trees or boats, and throws them out again half a mile below. It is avoided by keeping very close to the bank, on the south side. There are but a few miles portage between a branch of this river and the navigable waters of the river Mobile, which runs into the Gulf of Mexico.
Cumberland, or Shawanee river, intersects the boundary between Virginia and North Carolina sixty-seven miles from the Mississippi, and again one hundred and ninety-eight miles from the same river, a little above the entrance of Obey's river into the Cumberland. Its Clear fork crosses the same boundary about three hundred miles from the Mississippi. Cumberland is a very gentle stream, navigable for loaded batteaux eight hundred miles, without interruption; then intervene some rapids of fifteen miles in length, after which it is again navigable seventy miles upwards, which brings you within ten miles of the Cumberland mountains. It is about one hundred and twenty yards wide through its whole course, from the head of its navigation to its mouth.
The Wabash is a very beautiful river, four hundred yards wide at the mouth, and three hundred at St. Vincennes, which is a post one hundred miles above the mouth, in a direct line. Within this space there are two small rapids, which give very little obstruction to the navigation. It is four hundred yards wide at the mouth, and navigable thirty leagues upwards for canoes and small boats. From the mouth of Maple river to that of Eel river is about eighty miles in a direct line, the river continuing navigable, and from one to two hundred yards in width. The Eel river is one hundred and fifty yards wide, and affords at all times navigation for periaguas, to within eighteen miles of the Miami of the Lake. The Wabash, from the mouth of Eel river to Little river, a distance of fifty miles direct, is interrupted with frequent rapids and shoals, which obstruct the navigation, except in a swell. Little river affords navigation during a swell to within three miles of the Miami, which thence affords a similar navigation into Lake Erie, one hundred miles distant in a direct line. The Wabash overflows periodically in correspondence with the Ohio, and in some places two leagues from its banks.
Green River is navigable for loaded batteaux at all times fifty miles upwards; but it is then interrupted by impassable rapids, above which the navigation again commences and continues good thirty or forty miles to the mouth of Barren river.
Kentucky River is ninety yards wide at the mouth, and also at Boonsborough, eighty miles above. It affords a navigation for loaded batteaux one hundred and eighty miles in a direct line, in the winter tides.
The Great Miami of the Ohio, is two hundred yards wide at the mouth. At the Piccawee towns, seventy-five miles above, it is reduced to thirty yards; it is, nevertheless, navigable for loaded canoes fifty miles above these towns. The portage from its western branch into the Miami of Lake Erie, is five miles; that from its eastern branch into Sandusky river, is of nine miles.
Salt River is at all times navigable for loaded batteaux seventy or eighty miles. It is eighty yards wide at its mouth, and keeps that width to its fork, twenty-five miles above.
The Little Miami of the Ohio, is sixty or seventy yards wide at its mouth, sixty miles to its source, and affords no navigation.
The Sioto is two hundred and fifty yards wide at its mouth, which is in latitude 38° 22', and at the Saltlick towns, two hundred miles above the mouth, it is yet one hundred yards wide. To these towns it is navigable for loaded batteaux, and its eastern branch affords navigation almost to its source.
Great Sandy River is about sixty yards wide, and navigable sixty miles for loaded batteaux.
Guiandot is about the width of the river last mentioned, but is more rapid. It may be navigated by canoes sixty miles.
The Great Kanhaway is a river of considerable note for the fertility of its lands, and still more, as leading towards the head waters of James river. Nevertheless, it is doubtful whether its great and numerous rapids will admit a navigation, but at an expense to which it will require ages to render its inhabitants equal. The great obstacles begin at what are called the Great Falls, ninety miles above the mouth, below which are only five or six rapids, and these passable, with some difficulty, even at low water. From the falls to the mouth of Greenbriar is one hundred miles, and thence to the lead mines one hundred and twenty. It is two hundred and eighty yards wide at its mouth.
Hockhocking is eighty yards wide at its mouth, and yields navigation for loaded batteaux to the Press-place, sixty miles above its mouth.
The Little Kanhaway is one hundred and fifty yards wide at the mouth. It yields a navigation of ten miles only. Perhaps its northern branch, called Junius' creek, which interlocks with the western of Monongahela, may one day admit a shorter passage from the latter into the Ohio.
The Muskingum is two hundred and eighty yards wide at its mouth, and two hundred yards at the lower Indian towns, one hundred and fifty miles upwards. It is navigable for small batteaux to within one mile of a navigable part of Cuyahoga river, which runs into Lake Erie.
At Fort Pitt the river Ohio loses its name, branching into the Monongahela and Alleghany.
The Monongahela is four hundred yards wide at its mouth. From thence is twelve or fifteen miles to the mouth of Yohogany, where it is three hundred yards wide. Thence to Redstone by water is fifty miles, by land thirty. Then to the mouth of Cheat river by water forty miles, by land twenty-eight, the width continuing at three hundred yards, and the navigation good for boats. Thence the width is about two hundred yards to the western fork, fifty miles higher, and the navigation frequently interrupted by rapids, which, however, with a swell of two or three feet, become very passable for boats. It then admits light boats, except in dry seasons, sixty-five miles further to the head of Tygart's valley, presenting only some small rapids and falls of one or two feet perpendicular, and lessening in its width to twenty yards. The Western fork is navigable in the winter ten or fifteen miles towards the northern of the Little Kanhaway, and will admit a good wagon road to it. The Yahogany is the principal branch of this river. It passes through the Laurel mountain, about thirty miles from its mouth; is so far from three hundred to one hundred and fifty yards wide, and the navigation much obstructed in dry weather by rapids and shoals. In its passage through the mountain it makes very great falls, admitting no navigation for ten miles to the Turkey Foot. Thence to the Great Crossing, about twenty miles, it is again navigable, except in dry seasons, and at this place is two hundred yards wide. The sources of this river are divided from those of the Potomac by the Alleghany mountain. From the falls, where it intersects the Laurel mountain, to Fort Cumberland, the head of the navigation on the Potomac, is forty miles of very mountainous road. Wills' creek, at the mouth of which was Fort Cumberland, is thirty or forty yards wide, but affords no navigation as yet. Cheat river, another considerable branch of the Monongahela, is two hundred yards wide at its mouth, and one hundred yards at the Dunkard's settlement, fifty miles higher. It is navigable for boats, except in dry seasons. The boundary between Virginia and Pennsylvania crosses it about three or four miles above its mouth.
The Alleghany river, with a slight swell, affords navigation for light batteaux to Venango, at the mouth of French Creek, where it is two hundred yards wide, and is practised even to Le Bœuf, from whence there is a portage of fifteen miles to Presque Isle on the Lake Erie.
The country watered by the Mississippi and its eastern branches, constitutes five-eighths of the United States, two of which five-eighths are occupied by the Ohio and its waters; the residuary streams which run into the Gulf of Mexico, the Atlantic, and the St. Lawrence, water the remaining three-eighths.
Before we quit the subject of the western waters, we will take a view of their principal connections with the Atlantic. These are three; the Hudson river, the Potomac, and the Mississippi itself. Down the last will pass all heavy commodities. But the navigation through the Gulf of Mexico is so dangerous, and that up the Mississippi so difficult and tedious, that it is thought probable that European merchandise will not return through that channel. It is most likely that flour, timber, and other heavy articles will be floated on rafts, which will themselves be an article for sale as well as their loading, the navigators returning by land, or in light batteaux. There will, therefore, be a competition between the Hudson and Potomac rivers for the residue of the commerce of all the country westward of Lake Erie, on the waters of the lakes, of the Ohio, and upper parts of the Mississippi. To go to New York, that part of the trade which comes from the lakes or their waters, must first be brought into Lake Erie. Between Lake Superior and its waters and Huron, are the rapids of St. Mary, which will permit boats to pass, but not larger vessels. Lakes Huron and Michigan afford communication with Lake Erie by vessels of eight feet draught. That part of the trade which comes from the waters of the Mississippi must pass from them through some portage into the waters of the lakes. The portage from the Illinois river into a water of Michigan is of one mile only. From the Wabash, Miami, Muskingum, or Alleghany, are portages into the waters of Lake Erie, of from one to fifteen miles. When the commodities are brought into, and have passed through Lake Erie, there is between that and Ontario an interruption by the falls of Niagara, where the portage is of eight miles; and between Ontario and the Hudson river are portages at the falls of Onondago, a little above Oswego, of a quarter of a mile; from Wood creek to the Mohawks river two miles; at the little falls of the Mohawks river half a mile; and from Schenectady to Albany sixteen miles. Besides the increase of expense occasioned by frequent change of carriage, there is an increased risk of pillage produced by committing merchandise to a greater number of hands successively. The Potomac offers itself under the following circumstances: For the trade of the lakes and their waters westward of Lake Erie, when it shall have entered that lake, it must coast along its southern shore, on account of the number and excellence of its harbors; the northern, though shortest, having few harbors, and these unsafe. Having reached Cuyahoga, to proceed on to New York it will have eight hundred and twenty-five miles and five portages; whereas it is but four hundred and twenty-five miles to Alexandria, its emporium on the Potomac, if it turns into the Cuyahoga, and passes through that, Big Beaver, Ohio, Yohogany, (or Monongahela and Cheat,) and Potomac, and there are but two portages; the first of which, between Cuyahoga and Beaver, may be removed by uniting the sources of these waters, which are lakes in the neighborhood of each other, and in a champaign country; the other from the waters of Ohio to Potomac will be from fifteen to forty miles, according to the trouble which shall be taken to approach the two navigations. For the trade of the Ohio, or that which shall come into it from its own waters or the Mississippi, it is nearer through the Potomac to Alexandria than to New York by five hundred and eighty miles, and it is interrupted by one portage only. There is another circumstance of difference too. The lakes themselves never freeze, but the communications between them freeze, and the Hudson river is itself shut up by the ice three months in the year; whereas the channel to the Chesapeake leads directly into a warmer climate. The southern parts of it very rarely freeze at all, and whenever the northern do, it is so near the sources of the rivers, that the frequent floods to which they are there liable, break up the ice immediately, so that vessels may pass through the whole winter, subject only to accidental and short delays. Add to all this, that in case of war with our neighbors, the Anglo-Americans or the Indians, the route to New York becomes a frontier through almost its whole length, and all commerce through it ceases from that moment. But the channel to New York is already known to practice, whereas the upper waters of the Ohio and the Potomac, and the great falls of the latter, are yet to be cleared of their fixed obstructions. (A.)
Having no ports but our rivers and creeks, this Query has been answered under the preceding one.
For the particular geography of our mountains I must refer to Fry and Jefferson's map of Virginia; and to Evans' analysis of this map of America, for a more philosophical view of them than is to be found in any other work. It is worthy of notice, that our mountains are not solitary and scattered confusedly over the face of the country; but that they commence at about one hundred and fifty miles from the sea-coast, are disposed in ridges, one behind another, running nearly parallel with the sea-coast, though rather approaching it as they advance north-eastwardly. To the south-west, as the tract of country between the sea-coast and the Mississippi becomes narrower, the mountains converge into a single ridge, which, as it approaches the Gulf of Mexico, subsides into plain country, and gives rise to some of the waters of that gulf, and particularly to a river called the Apalachicola, probably from the Apalachies, an Indian nation formerly residing on it. Hence the mountains giving rise to that river, and seen from its various parts, were called the Appalachian mountains, being in fact the end or termination only of the great ridges passing through the continent. European geographers, however, extended the name northwardly as far as the mountains extended; some giving it, after their separation into different ridges, to the Blue Ridge, others to the North Mountain, others to the Alleghany, others to the Laurel Ridge, as may be seen by their different maps. But the fact I believe is, that none of these ridges were ever known by that name to the inhabitants, either native or emigrant, but as they saw them so called in European maps. In the same direction, generally, are the veins of limestone, coal, and other minerals hitherto discovered; and so range the falls of our great rivers. But the courses of the great rivers are at right angles with these. James and Potomac penetrate through all the ridges of mountains eastward of the Alleghany; that is, broken by no water course. It is in fact the spine of the country between the Atlantic on one side, and the Mississippi and St. Lawrence on the other. The passage of the Potomac through the Blue Ridge is, perhaps, one of the most stupendous scenes in nature. You stand on a very high point of land. On your right comes up the Shenandoah, having ranged along the foot of the mountain an hundred miles to seek a vent. On your left approaches the Potomac, in quest of a passage also. In the moment of their junction, they rush together against the mountain, rend it asunder, and pass off to the sea. The first glance of this scene hurries our senses into the opinion, that this earth has been created in time, that the mountains were formed first, that the rivers began to flow afterwards, that in this place, particularly, they have been dammed up by the Blue Ridge of mountains, and have formed an ocean which filled the whole valley; that continuing to rise they have at length broken over at this spot, and have torn the mountain down from its summit to its base. The piles of rock on each hand, but particularly on the Shenandoah, the evident marks of their disrupture and avulsion from their beds by the most powerful agents of nature, corroborate the impression. But the distant finishing which nature has given to the picture, is of a very different character. It is a true contrast to the foreground. It is as placid and delightful as that is wild and tremendous. For the mountain being cloven asunder, she presents to your eye, through the cleft, a small catch of smooth blue horizon, at an infinite distance in the plain country, inviting you, as it were, from the riot and tumult roaring around, to pass through the breach and participate of the calm below. Here the eye ultimately composes itself; and that way, too, the road happens actually to lead. You cross the Potomac above the junction, pass along its side through the base of the mountain for three miles, its terrible precipices hanging in fragments over you, and within about twenty miles reach Fredericktown, and the fine country round that. This scene is worth a voyage across the Atlantic. Yet here, as in the neighborhood of the Natural Bridge, are people who have passed their lives within half a dozen miles, and have never been to survey these monuments of a war between rivers and mountains, which must have shaken the earth itself to its centre. (B.)
The height of our mountains has not yet been estimated with any degree of exactness. The Alleghany being the great ridge which divides the waters of the Atlantic from those of the Mississippi, its summit is doubtless more elevated above the ocean than that of any other mountain. But its relative height, compared with the base on which it stands, is not so great as that of some others, the country rising behind the successive ridges like the steps of stairs. The mountains of the Blue Ridge, and of these the Peaks of Otter, are thought to be of a greater height, measured from their base, than any others in our country, and perhaps in North America. From data, which may found a tolerable conjecture, we suppose the highest peak to be about four thousand feet perpendicular, which is not a fifth part of the height of the mountains of South America, nor one-third of the height which would be necessary in our latitude to preserve ice in the open air unmelted through the year. The ridge of mountains next beyond the Blue Ridge, called by us the North mountain, is of the greatest extent; for which reason they were named by the Indians the endless mountains.
A substance supposed to be Pumice, found floating on the Mississippi, has induced a conjecture that there is a volcano on some of its waters; and as these are mostly known to their sources, except the Missouri, our expectations of verifying the conjecture would of course be led to the mountains which divide the waters of the Mexican Gulf from those of the South Sea; but no volcano having ever yet been known at such a distance from the sea, we must rather suppose that this floating substance has been erroneously deemed Pumice.
The only remarkable cascade in this country is that of the Falling Spring in Augusta. It is a water of James' river where it is called Jackson's river, rising in the warm spring mountains, about twenty miles south west of the warm spring, and flowing into that valley. About three-quarters of a mile from its source it falls over a rock two hundred feet into the valley below. The sheet of water is broken in its breadth by the rock, in two or three places, but not at all in its height. Between the sheet and the rock, at the bottom, you may walk across dry. This cataract will bear no comparison with that of Niagara as to the quantity of water composing it; the sheet being only twelve or fifteen feet wide above and somewhat more spread below; but it is half as high again, the latter being only one hundred and fifty-six feet, according to the mensuration made by order of M. Vaudreuil, Governor of Canada, and one hundred and thirty according to a more recent account.
An eye draught of Madison's cave on a scale of 67 feet to the inch. The arrows show where it descends or ascends.
In the lime-stone country there are many caverns of very considerable extent. The most noted is called Madison's Cave, and is on the north side of the Blue Ridge, near the intersection of the Rockingham and Augusta line with the south fork of the southern river of Shenandoah. It is in a hill of about two hundred feet perpendicular height, the ascent of which, on one side, is so steep that you may pitch a biscuit from its summit into the river which washes its base. The entrance of the cave is, in this side, about two-thirds of the way up. It extends into the earth about three hundred feet, branching into subordinate caverns, sometimes ascending a little, but more generally descending, and at length terminates, in two different places, at basins of water of unknown extent, and which I should judge to be nearly on a level with the water of the river; however, I do not think they are formed by refluent water from that, because they are never turbid; because they do not rise and fall in correspondence with that in times of flood or of drought; and because the water is always cool. It is probably one of the many reservoirs with which the interior parts of the earth are supposed to abound, and yield supplies to the fountains of water, distinguished from others only by being accessible. The vault of this cave is of solid lime-stone, from twenty to forty or fifty feet high; through which water is continually percolating. This, trickling down the sides of the cave, has incrusted them over in the form of elegant drapery; and dripping from the top of the vault generates on that and on the base below, stalactites of a conical form, some of which have met and formed massive columns.
Another of these caves is near the north mountain, in the county of Frederic, on the lands of Mr. Zane. The entrance into this is on the top of an extensive ridge. You descend thirty or forty feet, as into a well, from whence the cave extends, nearly horizontally, four hundred feet into the earth, preserving a breadth of from twenty to fifty feet, and a height of from five to twelve feet. After entering this cave a few feet, the mercury, which in the open air was 50°, rose to 57° of Fahrenheit's thermometer, answering to 11° of Reaumur's, and it continued at that to the remotest parts of the cave. The uniform temperature of the cellars of the observatory of Paris, which are ninety feet deep, and of all subterraneous cavities of any depth, where no chemical agencies may be supposed to produce a factitious heat, has been found to be 10° of Reaumur, equal to 54½° of Fahrenheit. The temperature of the cave above mentioned so nearly corresponds with this, that the difference may be ascribed to a difference of instruments.
At the Panther gap, in the ridge which divides the waters of the Crow and the Calf pasture, is what is called the Blowing Cave. It is in the side of a hill, is of about one hundred feet diameter, and emits constantly a current of air of such force as to keep the weeds prostrate to the distance of twenty yards before it. This current is strongest in dry, frosty weather, and in long spells of rain weakest. Regular inspirations and expirations of air, by caverns and fissures, have been probably enough accounted for by supposing them combined with intermitting fountains; as they must of course inhale air while their reservoirs are emptying themselves, and again emit it while they are filling. But a constant issue of air, only varying in its force as the weather is drier or damper, will require a new hypothesis. There is another blowing cave in the Cumberland mountain, about a mile from where it crosses the Carolina line. All we know of this is, that it is not constant, and that a fountain of water issues from it.
The Natural Bridge, the most sublime of nature's works, though not comprehended under the present head, must not be pretermitted. It is on the ascent of a hill, which seems to have been cloven through its length by some great convulsion. The fissure, just at the bridge, is, by some admeasurements, two hundred and seventy feet deep, by others only two hundred and five. It is about forty-five feet wide at the bottom and ninety feet at the top; this of course determines the length of the bridge, and its height from the water. Its breadth in the middle is about sixty feet, but more at the ends, and the thickness of the mass, at the summit of the arch, about forty feet. A part of this thickness is constituted by a coat of earth, which gives growth to many large trees. The residue, with the hill on both sides, is one solid rock of lime-stone. The arch approaches the semi-elliptical form; but the larger axis of the ellipsis, which would be the cord of the arch, is many times longer than the transverse. Though the sides of this bridge are provided in some parts with a parapet of fixed rocks, yet few men have resolution to walk to them, and look over into the abyss. You involuntarily fall on your hands and feet, creep to the parapet, and peep over it. Looking down from this height about a minute, gave me a violent head-ache. If the view from the top be painful and intolerable, that from below is delightful in an equal extreme. It is impossible for the emotions arising from the sublime to be felt beyond what they are here; so beautiful an arch, so elevated, so light, and springing as it were up to heaven! the rapture of the spectator is really indescribable! The fissure continuing narrow, deep, and straight, for a considerable distance above and below the bridge, opens a short but very pleasing view of the North mountain on one side and the Blue Ridge on the other, at the distance each of them of about five miles. This bridge is in the county of Rockbridge, to which it has given name, and affords a public and commodious passage over a valley which cannot be crossed elsewhere for a considerable distance. The stream passing under it is called Cedar-creek. It is a water of James' river, and sufficient in the driest seasons to turn a grist-mill, though its fountain is not more than two miles above.[2]
I knew a single instance of gold found in this State. It was interspersed in small specks through a lump of ore of about four pounds weight, which yielded seventeen pennyweights of gold, of extraordinary ductility. This ore was found on the north side of Rappahanoc, about four miles below the falls. I never heard of any other indication of gold in its neighborhood.
On the Great Kanhaway, opposite to the mouth of Cripple creek, and about twenty-five miles from our southern boundary, in the county of Montgomery, are mines of lead. The metal is mixed, sometimes with earth, and sometimes with rock, which requires the force of gunpowder to open it; and is accompanied with a portion of silver too small to be worth separation under any process hitherto attempted there. The proportion yielded is from fifty to eighty pounds of pure metal from one hundred pounds of washed ore. The most common is that of sixty to one hundred pounds. The veins are sometimes most flattering, at others they disappear suddenly and totally. They enter the side of the hill and proceed horizontally. Two of them are wrought at present by the public, the best of which is one hundred yards under the hill. These would employ about fifty laborers to advantage. We have not, however, more than thirty generally, and these cultivate their own corn. They have produced sixty tons of lead in the year; but the general quantity is from twenty to twenty-five tons. The present furnace is a mile from the ore bank and on the opposite side of the river. The ore is first wagoned to the river, a quarter of a mile, then laden on board of canoes and carried across the river, which is there about two hundred yards wide, and then again taken into wagons and carried to the furnace. This mode was originally adopted that they might avail themselves of a good situation on a creek for a pounding mill; but it would be easy to have the furnace and pounding mill on the same side of the river, which would yield water, without any dam, by a canal of about half a mile in length. From the furnace the lead is transported one hundred and thirty miles along a good road, leading through the peaks of Otter to Lynch's ferry, or Winston's on James' river, from whence it is carried by water about the same distance to Westham. This land carriage may be greatly shortened, by delivering the lead on James' river, above the Blue Ridge, from whence a ton weight has been brought on two canoes. The Great Kanhaway has considerable falls in the neighborhood of the mines. About seven miles below are three falls, of three or four feet perpendicular each; and three miles above is a rapid of three miles continuance, which has been compared in its descent to the great falls of James' river. Yet it is the opinion, that they may be laid open for useful navigation, so as to reduce very much the portage between the Kanhaway and James' river.
A valuable lead mine is said to have been lately discovered in Cumberland, below the mouth of Red river. The greatest, however, known in the western country, are on the Mississippi, extending from the mouth of Rock river one hundred and fifty miles upwards. These are not wrought, the lead used in that country being from the banks on the Spanish side of the Mississippi, opposite to Kaskaskia.
