MINERAL WEALTH OF VIRGINIA.

The following interesting communication from Peter A. Browne, Esq. of

Philadelphia, was submitted last winter, by the Governor of Virginia,

to the General Assembly. It was printed with the documents accompanying

the annual message, and bound up with the legislative journals, but has

had no other publicity. It is therefore _new_ to nineteen-twentieths,

if not to ALL of our readers. We confess we feel somewhat mortified,

that the valuable hints and suggestions thrown out by an intelligent

and scientific stranger, should have failed to attract the attention of

our public functionaries. We are not without hope, however, that a

subject of such vital importance as a geological survey of the state,

will claim the earnest and speedy consideration of the people, as well

as their representatives. It is one of those subjects upon which all

parties, however divided by sectional jealousies or other adverse

views, may meet on common ground, and unite in harmonious action. There

is no portion of the commonwealth which is not deeply interested in the

development of its mineral wealth--none which ought not to lend its

hearty sanction to a scientific survey of the country by a skilful

geologist. To say nothing of the noble example of other states--among

them some of our youngest sisters--our interests are too deeply

involved in the proposed undertaking, longer to defer it.

Agriculture,--commerce,--the arts,--are alike concerned in the

successful prosecution of a work which promises to each such essential

benefits. The people of Virginia have been too long ignorant and

unmindful of their own vast resources. Who would have dreamed a few

years since, that a vein of precious gold, which, for two centuries,

had escaped observation, actually enriched our soil? Who now can form

an adequate conception of the various hidden treasures which science

and enterprise may bring to light. Can the paltry consideration of a

few thousand dollars expense, outweigh the magnificent advantages which

are likely to result? Shall the present generation fold its arms in

supineness, and leave every thing to be done by posterity? We earnestly

exhort our legislators to take the subject into serious consideration.

The writer of the subjoined communication will be pleased to learn that

the mineral springs of the state, (which might in themselves be made a

source of boundless wealth,) have been subjected to careful analysis

during the past summer, by an able chemical professor in one of our

colleges. It is understood that the results of his observation will in

due time be laid before the public.

_Philadelphia, Sept. 30, 1833._

SIR,--Although I have not the honor of a personal acquaintance with

you, I have no hesitation in making the present appeal to your

patriotism and wisdom, not doubting but that I shall find in the great

and growing interest of the subject to the country at large, and

particularly to that portion of the Union over which you preside with

so much dignity and discretion, a sufficient apology for occupying so

much of your valuable time, as will enable you to give the present

communication an attentive perusal.

I have recently returned from a _geological_ excursion to Virginia. I

entered the state near the head waters of the Potomac, passed thence to

Winchester, followed the course of that fine valley to the Natural

bridge; retracing my steps, I turned westwardly at Staunton, crossed

the mountain at Jennings's gap, and visited the justly celebrated

medicinal springs in that region; returning, I went from Staunton

through Charlottesville to Richmond, and down the James to its mouth.

When this tour is taken in connection with a former visit to Wheeling,

it will be conceded that I have seen enough of the state, to enable me

to form a rough estimate of its geological and mineralogical

importance; and I do assure you, sir, that although my anticipations

were far from being meager, I was astonished at the vastness and

variety of interesting objects in that department of natural history,

that were constantly developing themselves, inviting the mind of man to

reflection, and his hands to industry, and displaying at every step the

wisdom and beneficence of the great Creator.

I determined upon respectfully suggesting to your excellency the

expediency of a topographical, geological, mineralogical and

oryctological survey of Virginia. Should the enlightened

representatives of the freemen of your state concur in this opinion, it

will redound to the honor of all concerned, by the encouragement it

will give to the study of the natural sciences--by the enhancement in

value of lands in the interior, thereby enriching the state and its

citizens, and giving a very proper check to unnatural migrations to the

extreme west, by bringing to light and usefulness innumerable valuable

crude materials, thereby not only enlarging the field of manufactures

and the useful arts, but furnishing carrying for the canals and roads

already constructed, and assisting in new internal improvements in

locations of equal importance. That I may not appear to be too

enthusiastic, pardon me for pointing out some of the most obvious

features in the geology of Virginia. Whether we consider the comfort

and convenience of our species, or the industry and prosperity of a

state, there is no mineral production that can outvie in importance

that of _coal_. In this country, where we have hitherto always had a

superabundance of fuel, owing to the vast extent of our natural

forests, the importance of a constant and abundant supply is not felt,

and we are too apt to neglect properly to appreciate its value, but it

is not so elsewhere, and a moment's reflection will shew that it ought

not to be so _here_. Without fuel, of what use would be to us the

metallic ores? for instance iron, which is now moulded, drawn and

worked into thousands and tens of thousands of useful instruments, from

a knife, to the complicated machinery of a steam engine, would forever

remain an indissoluble and useless mass of matter without the aid of

fuel--even the steam engine itself, that colossus of modern machinery,

without the assistance of fire would be inactive and impotent.

The Rev. Mr. Conybeare, an eminent English geologist, speaking of the

coal veins (or coal measures, as they are there called,) of his

country, thus expresses himself:

"The manufacturing industry of this island, colossal as is the fabric

which it has raised, rests principally on no other base than our

fortunate position with regard to the rocks of this series. Should our

coal mines ever be exhausted, it would melt away at once, and it need

not be said, that the effect produced on private and domestic comfort

would be equally fatal with diminution of public wealth; we should lose

many of the advantages of our high civilization, and much of our

cultivated grounds must be again shaded with forests, to afford fuel to

a remnant of our present population. That there is a progressive

tendency to approach this limit, is certain, but ages may yet pass

before it is felt very sensibly; and when it does approach, the

increasing difficulty and expense of working the mines of coal, will

operate, by successive and gradual checks, against its consumption,

through a long period, so that the transition may not be very violent;

our manufactures would first feel the shock; the excess of population,

supported by them, would cease to be called into existence, as the

demand for their labor ceased; the cultivation of poor lands would

become less profitable, and their conversion into forests more so."

Where is the state in this union--I might, perhaps, safely ask, where

is the country in the world, that can surpass Virginia in the variety

of position and abundance of supply of this valuable combustible? She

possesses, not only in common with her sister states, a liberal

quantity of bituminous coal in her western and carbonaceous regions,

where, according to geological calculations, bituminous coal might be

reasonably expected to be found; but in the eastern division of the

state, within a few miles of the tide water of a majestic stream, which

empties its ample waters into the Atlantic ocean, in a geological

position, where bituminous coal never would have been sought after,

because bituminous coal could not there have ever been expected to have

been found, bituminous coal of a good quality, and apparently in great

abundance, has been found; nature seeming, as it were, in this

instance, to enable her to favor an otherwise highly favored land, to

have defied all her own rules, and baffled the skill of the gravest

geologist, by depositing bituminous coal upon the naked and barren

bosom of the uncarbonaceous granite! I have often wondered why this

anomaly did not strike the capacious and highly gifted mind of

Jefferson, and why he, or some other of the many reflecting men of

Virginia, was not led by it to inquire, what else there might be in

store for the good people of that state? By neglecting to seek for

them, we ungratefully reject the proffered kindness of our Creator; the

laws of inanimate matter are, in this respect, in unison with those

that govern animated nature; we are furnished with the material and

means, but in order to stimulate us to useful and healthful industry,

we must labor in their appropriation. God gives us the earth and the

seed, but we must plough and sow, or we can never reap; so he has

bountifully placed within our reach innumerable valuable rocks,

minerals and combustibles, but to enjoy them, we must delve into the

bowels of the earth--and having found them, we must, by various

laborious processes, render them fit for our use. To those who are

accustomed to regard these things, it is difficult to determine which

causes the most painful sensations, to observe how few coal mines, in

comparison to what might be, are opened in the neighborhood of

Richmond, or the want of skill exhibited in the selection and working

of those recently opened. Nor is the deposite of the bituminous coal

upon the granite, the only geological anomaly of this quarter.

Proceeding from Charlottesville towards Richmond, almost immediately

after you leave the Talcose formation of the Blue Ridge, you are

astonished at the fertility of the soil; you can scarcely persuade

yourself that you are travelling over a country of primitive rocks.

Soon, however, you discover that the fertility is not universal, but

confined to patches of a brick-red covering, that overlay the

disintegrated materials of the primordial formations, and upon seeking

further into this curious matter, your surprise is not a little

increased, upon discovering that this brick-red covering owes its

existence to the disintegration of a rock, which, in most other places,

is exceedingly slow to decompose, and which, when decomposed, forms a

cold and inhospitable soil. It is the _hornblende sienite_. Here it is

surcharged with iron, which oxidating by exposure to the atmosphere and

moisture, the rock freely disintegrates, and the oxide of iron being

set at liberty, imparts its coloring to the ground, and fertilizes the

soil in an extraordinary degree.

Professor Hitchcock, in his report of a geological survey of

Massachusetts, makes the following remarks in relation to the effect of

iron upon a soil:

"No ore except iron occurs in sufficient quantity in the state, to

deserve notice in an agricultural point of view. In the west part of

Worcester county, the soil, for a width of several miles across the

whole state, is so highly impregnated with the _oxide of iron_, as to

receive from it a very deep tinge of what is called iron rust. This is

particularly the case in the low grounds; where are frequently found

beds of bog ore. I do not know very definitely the effect of this iron

upon vegetation; but, judging from the general excellence of the farms

in the Brookfields, Sturbridge, Hardwicke, New Braintree, Barae,

Hubbardston, &c., I should presume it to be good. Certainly, it cannot

be injurious; for no part of the county exceeds the towns just named,

in the appearance of its farming interest--and nearly all the county,

as may be seen by the map, is of one formation. It would be an

interesting problem, which in that county can be solved, to determine

the precise influence of a soil highly ferruginous upon vegetation."

Next in geological and statistical importance, I would place the

mineral springs of Virginia; and these would form a legitimate subject

of investigation to those who should be appointed to conduct a

geological survey.

I am not aware of any portion of country of the same extent, possessing

an equal number and variety of mineral springs, as the counties of

Bath, Greenbrier and Monroe. This is a subject upon which one might

easily compose a book, but I must confine myself to a few lines. The

waters are thermal and cold; the former of various degrees of

intensity. They hold in solution a variety of metals, earths, acids,

and alkalies, combined in various proportions, and suited to relieve

the sufferings of invalids from a number of diseases. Mineral springs

of less interest than these, have excited the attention of the learned

in almost every age and country; and Virginia owes it to her high

mental standing, independently of every other consideration, to assist

the cause of science, by investigating the causes of the high

temperature, and making accurate analyses of these waters. It is the

duty of states, as it is of individuals, to furnish their quota to the

general stock of information; and this is peculiarly the duty of a

republican state, whose happiness, nay, whose very political existence,

depends upon an improved state of the minds of its citizens. Mr. John

Mason Good, in his "Book of Nature," after describing the barren state

of society in the middle ages, says, "we have thus rapidly travelled

over a wide and dreary desert, that, like the sandy wastes of Africa,

has seldom been found refreshed by spots of verdure, and what is the

moral? That ignorance is ever associated with wretchedness and vice,

and knowledge with happiness and virtue. Their connections are

indissoluble; they are woven in the very texture of things, and

constitute the only substantial difference between man and man," and I

would add, between state and state.

Has the heat of these waters any connection with volcanic phenomena? Or

is the temperature entirely chemical, originating in the decomposition

of sulphuret of iron, as I suggested some years ago in a paper

published upon the subject? At the Hot Springs, the hot sulphur water

and the cold pure water, issue out of the calcareous rock at the base

of the Warm Spring mountain, within a few feet of each other. One of

these Virginia Springs, makes a copious deposite of calcareous tufa;

and at another, you perceive newly formed crystals of sulphate of iron.

The White Sulphur Spring takes its name from a rich white deposite, and

the Red Sulphur from one of that color. If this is not an uncommon and

a highly interesting section of country, calling aloud for

investigation, and meriting legislative interference, then have I taken

an entirely erroneous view of the subject.

The Warm Spring mountain is white sandstone. The rocks of the valley of

the Hot Springs are calcareous, argillaceous and silecious; they are

all nearly vertical. At first the two former, and afterwards the two

latter, alternate. They have all been deposited in a horizontal

position, and between their narrow strata are thin layers of clay

covering organic remains.--Those of the lime and slate are principally

zoophytes. That of the silecious is the fossil described by Doctor R.

Harlan, from a specimen obtained by me in the western part of the state

of New York. He supposed it to be a now extinct vegetable fossil of the

family fucoides, and he has called it _Fucoide Brongniard_,--in honor

of M. Brongniard. But I suppose it to be _animal_, and to belong to the

family of the Encrinites.[1]

[Footnote 1: See an essay of Richard C. Taylor, F. G. S. on the

geological position of certain beds which contain numerous fossil

marine plants of the family fucoides; near Lewistown, Mifflin county,

Pennsylvania, in vol. I. part I. of the Transactions of the Geological

Society of Pennsylvania, page 1.]

The mountain ranges of Virginia are more numerous, and the valleys

consequently narrower, than they are in Pennsylvania; but some of them

are very interesting. The great valley, as it is sometimes called, or

par excellence, _the valley_, situate between the Blue Ridge and the

North and Alleghany Mountain, is by far the most extensive. The rocks

often obtrude, rendering the soil rather scanty, but nevertheless this

is a fine district of country.

I could find no fossils in this rock. In regard to the metallic ores, I

would observe, that I discovered sufficient indications of their

existing in Virginia in quantity sufficient to justify a more accurate

examination. Iron abounds in almost every part of the western section

of the state. Traces of copper, lead, manganese and chrome, have also

been discovered near the Blue Ridge; and the gold of Orange County is

equal to any found in the Carolinas or Georgia.

I have never seen any thing that exceeds the richness and variety of

coloring of the serpentine of the Blue Ridge. This mineral is easily

cut, and the fineness and closeness of the grain renders it susceptible

of a high polish. At Zoblitz in Saxony, several hundred persons are

employed in its manufacture. Besides the minerals belonging to the

Talcose formation, and generally accompanying serpentine, are many of

them valuable in the arts--for instance, steatite, (soap stone,) talc,

chromate of iron, clorite slate, and native magnesia. A geological

survey would, most probably, lead to the discovery of most of these

minerals.

I could make large additions to this communication, but for the fear of

trespassing upon your patience. I will, therefore, close my

observations with noticing two instances of want of confidence in the

mineral productions of your own state, which I am persuaded that a

geological survey would tend to correct. I met many wagons loaded with

sulphate of lime (gypsum,) from Nova Scotia, being taken to the

interior to be used as a manure; but I did not see one wagon employed

to bring carbonate of lime (common lime stone,) from the inexhaustible

quarries of the great valley to any other district to be used for the

same purpose. In the beautiful and flourishing city of Richmond, I

observed the fronts of two stores fitting up in the new and fashionable

style with granite (so called,) (sienite,) from Massachusetts, while

there exists in the James river, and on its banks, in the immediate

vicinity of the town, rocks of a superior quality, in quantities amply

sufficient to build a dozen cities.

I have the honor to be, sir,

Your obedient servant,
