May 18. Carcassonne. Castelnaudari. Opposite to Carcassonne the canal receives the river Fresquel, about thirty yards wide, which is its substantial supply of water from hence to Beziers. From Beziers to Agde the river Orb furnishes it, and the Eraut, from Agde to the Etang de Thau. By means of the écluse ronde at Agde, the waters of the Eraut can be thrown towards Beziers, to aid those of the Orb, as far as the écluse de Porcaraigne, nine geometrical miles. Where the Fresquel enters the canal, there is, on the opposite side, a waste, to let off the superfluous waters. The horse-way is continued over this waste, by a bridge of stone of eighteen arches. I observe them fishing in the canal, with a skimming net of about fifteen feet diameter, with which they tell me they catch carp. Flax in blossom. Neither strawberries nor peas yet at Carcassonne. The Windsor-bean just come to table. From the écluse de la Lande we see the last olive trees near a metairée, or farm-house-, called La Lande. On a review of what I have seen and heard of this tree, the following seem to be its northern limits. Beginning on the Atlantic, at the Pyrenees, and along them to the meridian of La Lande, or of Carcassonne; up that meridian to the Cevennes, as they begin just there to raise themselves high enough to afford it shelter. Along the Cevennes, to the parallel of forty-five degrees of latitude, and along that parallel (crossing the Rhone near the mouth of the Isere) to the Alps; thence along the Alps and Apennines, to what parallel of latitude I know not. Yet here the tracing of the line becomes the most interesting. For from the Atlantic, so far we see this production the effect of shelter and latitude combined. But where does it venture to launch forth unprotected by shelter, and by the mere force of latitude alone? Where, for instance, does its northern limit cross the Adriatic? I learn, that the olive tree resists cold to eight degrees of Reaumur below the freezing-point, which corresponds to fourteen above zero of Fahrenheit: and that the orange resists to four degrees below freezing of Reaumur, which is twenty-three degrees above zero of Fahrenheit.
May 19. Castelnaudari. St. Feriol. Escamaze. Lampy. Some sheep and cattle; no enclosures. St. Feriol, Escamaze, and Lampy are in the montagnes noires. The country almost entirely waste. Some of it in shrubbery. The voute d’Escamaze is of one hundred and thirty-five yards. Round about Castelnaudari the country is hilly, as it has been constantly from Beziers; it is very rich. Where it is plain, or nearly plain, the soil is black: in general, however, it is hilly and reddish, and in corn. They cultivate a great deal of Indian corn here, which they call millet; it is planted, but not yet up.
May 20. Castelnaudari. Naurouze. Villefranche. Baziege. At Naurouze is the highest ground which the canal had to pass between the two seas. It became necessary, then, to find water still higher to bring it here. The river Fresquel heading by its two principal branches in the montagnes noires, a considerable distance off to the eastward, the springs of the most western one were brought together, and conducted to Naurouze, where its waters are divided, part furnishing the canal towards the ocean, the rest towards the Mediterranean, as far as the écluse de Fresquel, where, as has been before noted, the Lampy branch and the Alzau, under the name of the Fresquel, enter.
May 20. They have found that a lock of six pieds is best; however, eight pieds is well enough. Beyond this, it is bad. Monsieur Pin tells me of a lock of thirty pieds made in Sweden, of which it is impossible to open the gates. They therefore divided it into four locks. The small gates of the locks of this canal have six square pieds of surface. They tried the machinery of the jack for opening them. They were more easily opened, but very subject to be deranged, however strongly made. They returned, therefore, to the original wooden screw, which is excessively slow and laborious. I calculate that five minutes are lost at every basin by this screw, which, on the whole number of basins, is one eighth of the time necessary to navigate the canal: and of course, if a method of lifting the gate at one stroke could be found, it would reduce the passage from eight to seven days, and the freight equally. I suggested to Monsieur Pin and others a quadrantal gate, turning on a pivot, and lifted by a lever like a pump-handle, aided by a windlass and cord, if necessary. He will try it, and inform me of the success. The price of transportation from Cette to Bordeaux, through the canal and Garonne is – the quintal: round by the straits of Gibraltar is –. Two hundred and forty barks, the largest of twenty-two hundred quintals (or say, in general, of one hundred tons), suffice to perform the business of this canal, which is stationary, having neither increased nor diminished for many years. When pressed, they can pass and repass between Toulouse and Beziers in fourteen days; but sixteen is the common period. The canal is navigated ten and a half months of the year: the other month and a half being necessary to lay it dry, cleanse it, and repair the works. This is done in July and August, when there would perhaps be a want of water.
May 21. Baziège. Toulouse. The country continues hilly, but very rich. It is in mulberries, willows, some vines, corn, maize, pasture, beans, flax. A great number of chateaux and good houses in the neighborhood of the canal. The people partly in farm-houses, partly in villages. I suspect that the farm-houses are occupied by the farmers, while the laborers (who are mostly by the day) reside in the villages. Neither strawberries nor pease yet at Baziege or Toulouse. Near the latter are some fields of yellow clover.
At Toulouse the canal ends. It has four communications with the Mediterranean. 1. Through the ponds of Thau, Frontignan, Palavas, Maguelone, and Manjo, the canal de la Radela Aigues-mortes, le canal des Salines de Pecair, and the arm of the Rhone called Bras de Fer, which ends at Fourgues, opposite to Arles, and thence down the Rhone. 2. At Cette, by a canal of a few hundred toises, leading out of the Etang de Thau into the sea. The vessels pass the Etang, though a length of nine thousand toises, with sails. 3. At Agde, by the river Eraut, twenty-five hundred toises. It has but five or six pieds of water at its mouth. It is joined to the canal at the upper part of this communication, by a branch of a canal two hundred and seventy toises long. 4. At Narbonne, by a canal they are now opening, which leads from the great canal near the aqueduct of the river Cesse, twenty-six hundred toises, into the Aude. This new canal will have five lock-basins, of about twelve pieds fall each. Then you are to cross the Aude very obliquely, and descend a branch of it six thousand toises, through four lock-basins to Narbonne, and from Narbonne down the same branch, twelve hundred toises into the Etang de Sigen, across that Etang four thousand toises, issuing at an inlet, called Grau de la Nouvelle, into the Gulf of Lyons. But only vessels of thirty or forty tons can enter this inlet. Of these four communications, that of Cette only leads to a deep sea-port, because the exit is there by a canal, and not a river. Those by the Rhone, Eraut, and Aude, are blocked up by bars at the mouths of those rivers. It is remarkable, that all the rivers running into the Mediterranean are obstructed at their entrance by bars and shallows, which often change their position. This is the case with the Nile, Tiber, the Po, the Lez, le Lyoron, the Orbe, the Gly, the Tech, the Tet, he. Indeed, the formation of these bars seems not confined to the mouths of the rivers, though it takes place at them more certainly. Along almost the whole of the coast, from Marseilles towards the Pyrenees, banks of sand are thrown up parallel with the coast, which have insulated portions of the sea, that is, formed them into etangs, ponds, or sounds, through which here and there narrow and shallow inlets only are preserved by the currents of the rivers. These sounds fill up in time, with the mud and sand deposited in them by the rivers. Thus the Etang de Vendres, navigated formerly by vessels of sixty tons, is now nearly filled up by the mud and sand of the Aude. The Vistre and Vidourle, which formerly emptied themselves into the Gulf of Lyons, are now received by the Etangs de Manjo and Aiguesmortes, that is to say, the part of the Gulf of Lyons, which formerly received, and still receives those rivers, is now cut off from the sea by a bar of sand, which has been thrown up in it, and has formed it into sounds. Other proofs that the land gains there on the sea, are, that the towns of St. Giles and Notre Dame d’Asposts, formerly seaports, are no far from the sea, and that Aiguesmortes, where are still to be seen the iron rings to which vessels were formerly moored, and where St. Louis embarked for Palestine, has now in its vicinities only ponds, which cannot be navigated, and communicates with the sea by an inlet, called Grau du Roy, through which only fishing-barks can pass. It is pretty well established, that all the Delta of Egypt has been formed by the depositions of the Nile, and the alluvions of the sea, and it is probable that that operation is still going on. Has this peculiarity of the Mediterranean any connection with the scantiness of its tides, which, even at the equinoxes, are of two or three feet only? The communication from the western end of the canal to the ocean, is by the river Garonne. This is navigated by flat boats of eight hundred quintals, when the water is well; but when it is scanty, these boats carry only two hundred quintals, till they get to the mouth of the Tarn. It has been proposed to open a canal that far from Toulouse, along the right side of the river.
May 22. Toulouse. 23. Agen. 24. Castres. Bordeaux. The Garonne, and rivers emptying into it, make extensive and rich plains, which are in mulberries, willows, corn, maize, pasture, beans, and flax. The hills are in corn, maize, beans, and a considerable proportion of vines. There seems to be as much maize as corn in this country. Of the latter, there is more rye than wheat. The maize is now up, and about three inches high. It is sowed in rows two feet or two and a half feet apart, and is pretty thick in the row. Doubtless they mean to thin it. There is a great deal of a forage they call farouche. It is a species of red trefoil, with few leaves, a very coarse stalk, and a cylindrical blossom of two inches in length, and three quarters of an inch in diameter, consisting of floscules, exactly as does that of the red clover. It seems to be a coarse food, but very plentiful. They say it is for their oxen. These are very fine, large, and cream-colored. The services of the farm and of transportation are performed chiefly by them. There are a few horses and asses, but no mules. Even in the city of Bordeaux we see scarcely any beasts of draught but oxen. When we cross the Garonne at Langon, we find the plains entirely of sand and gravel, and they continue so to Bordeaux. Where they are capable of any thing, they are in vines, which are in rows, four, five, or six feet apart, and sometimes more. Near Langon is Sauterne, where the best white wines of Bordeaux are made. The waste lands are in fern, furze, shrubbery, and dwarf trees. The farmers live on their farms. At Agen, Castres, Bordeaux, strawberries and pease are now brought to table; so that the country on the canal of Languedoc seems to have later seasons than that east and west of it. What can be the cause? To the eastward, the protection of the Cevennes makes the warm season advance sooner. Does the neighborhood of the Mediterranean co-operate? And does that of the ocean mollify and advance the season to the westward? There are ortolans at Agen, but none at Bordeaux. The buildings on the canal and the Garonne are mostly of brick, the size of the bricks the same with that of the ancient Roman brick, as seen in the remains of their buildings in this country. In those of a circus at Bordeaux, considerable portions of which are standing, I measured the bricks, and found them nineteen or twenty inches long, eleven or twelve inches wide, and from one and a half to two inches thick; their texture as fine, compact, and solid as that of porcelain. The bricks now made, though of the same dimensions, are not so fine. They are burnt in a kind of furnace, and make excellent work. The elm tree shows itself at Bordeaux peculiarly proper for being spread flat for arbors. Many are done in this way on the Quay des Charterons. Strawberries, pease, and cherries at Bordeaux.
May 24, 25, 26, 27, 28. Bordeaux. The cantons in which the most celebrated wines of Bordeaux are made, are Medoc down the river, Grave adjoining the city, and the parishes next above; all on the same side of the river. In the first, is made red wine principally, in the two last, white. In Medoc they plant the vines in cross-rows of three and a half pieds. They keep them so low, that poles extended along the rows one way, horizontally, about fifteen or eighteen inches above the ground, serve to tie the vines to, and leave the cross row open to the plough. In Grave they set the plants in quincunx, i.e. in equilateral triangles of three and a half pieds every side; and they stick a pole of six or eight feet high to every vine, separately. The vine-stock is sometimes three or four feet high. They find these two methods equal in culture, duration, quantity, and quality. The former, however, admits the alternative of tending by hand or with the plough. The grafting of the vine, though a critical operation, is practised with success. When the graft has taken, they bend it into the earth, and let it take root above the scar. They begin to yield an indifferent wine at three years old, but not a good one till twenty-five years, nor after eighty, when they begin to yield less, and worse, and must be renewed. They give three or four workings in the year, each worth seventy or seventy-five livres the journal, which is of eight hundred and forty square ioises, and contains about three thousand plants. They dung a little in Medoc and Grave, because of the poverty of the soil; but very little; as more would affect the wine. The journal yields, communions annis, about three pièces (of two hundred and forty, or two hundred and fifty bottles each). The vineyards of first quality are all worked by their proprietors. Those of the second, rent for three hundred livres the journal: those of third, at two hundred livres. They employ a kind of overseer at four or five hundred livres the year, finding him lodging and drink: but he feeds himself. He superintends and directs, though he is expected to work but little. If the proprietor has a garden, the overseer tends that. They never hire laborers by the year. The day wages for a man are thirty sous, a woman’s fifteen sous, feeding themselves. The women make the bundles of sarment, weed, pull off the snails, tie the vines, and gather the grapes. During the vintage they are paid high, and fed well.
Of Red wines, there are four vineyards of the first quality; viz. 1. Chateau Margau, belonging to the Marquis d’Agincourt, who makes about one hundred and fifty tons, of one thousand bottles each. He has engaged to Jernon, a merchant. 2. La Tour de Segur, en Saint Lambert, belonging to Monsieur Miresmenil, who makes one hundred and twenty-five tons. 3. Hautbrion, belonging two-thirds to M. le Comte de Femelle, who has engaged to Barton, a merchant: the other third to the Comte de Toulouse, at Toulouse. The whole is seventy-five tons. 4. Chateau de la Fite, belonging to the President Pichard, at Bordeaux, who makes one hundred and seventy-five tons. The wines of the three first, are not in perfection till four years old: those of de la Fite, being somewhat lighter, are good at three years; that is, the crop of 1786 is good in the spring of 1789. These growths, of the year 1783, sell now at two thousand livres the ton; those of 1784, on account of the superior quality of that vintage, sell at twenty-four hundred livres; those of 1785, at eighteen hundred livres; those of 1786, at eighteen hundred livres, though they had sold at first for only fifteen hundred livres. Red wines of the second quality, are Rozan, Dabbadie or Lionville, la Rose, Qui-rouen, Durfort; in all eight hundred tons, which sell at one thousand livres, new. The third class, are Galons, Mouton, Gassie, Arboete, Pontette, de Ferme, Candale; in all two thousand tons, at eight or nine hundred livres. After these, they are reckoned common wines, and sell from five hundred livres, down to one hundred and twenty livres, the ton. All red wines decline after a certain age, losing color, flavor, and body. Those of Bordeaux begin to decline at about seven years old.
Of White wines, those made in the canton of Grave, are most esteemed at Bordeaux. The best crops are, 1. Pontac, which formerly belonged to M. de Pontac, but now to M. de Lamont. He makes forty tons, which sell at four hundred livres, new. 2. St. Brise, belonging to M. de Pontac; thirty tons, at three hundred and fifty livres. 3. De Carbonius, belonging to the Benedictine monks, who make fifty tons, and never selling till three or four years old, get eight hundred livres the ton. Those made in the three parishes next above Grave, and more esteemed at Paris, are, 1. Sauterne. The best crop belongs to M. Diquem at Bordeaux, or to M. de Salus, his son-in-law; one hundred and fifty tons, at three hundred livres, new, and six hundred livres, old. The next best crop is M. de Fillotte’s, one hundred tons, sold at the same price. 2. Prignac. The best is the President du Roy’s, at Bordeaux. He makes one hundred and seventy-five tons, which sell at three hundred livres, new, and six hundred livres, old. Those of 1784, for their extraordinary quality, sell at eight hundred livres. 3. Barsac. The best belongs to the President Pichard, who makes one hundred and fifty tons, at two hundred and eighteen livres, new, and six hundred livres, old. Sauterne is the pleasantest; next Prignac, and lastly Barsac: but Barsac is the strongest; next Prignac, and lastly Sauterne; and all stronger than Grave. There are other good crops made in the same parishes of Sauterne, Prignac, and Barsac; but none as good as these. There is a virgin wine, which, though made of a red grape, is of a light rose color, because, being made without pressure, the coloring matter of the skin does not mix with the juice. There are other white wines, from the preceding prices down to seventy-five livres. In general, the white wines keep longest. They will be in perfection till fifteen or twenty years of age. The best vintage now to be bought, is of 1784; both of red and white. There has been no other good year since 1779. The celebrated vineyards before mentioned, are plains, as is generally the canton of Medoc, and that of the Grave. The soil of Hautbrion, particularly, which I examined, is a sand, in which is near as much round gravel or small stone, and very little loam: and this is the general soil of Medoc. That of Pontac, which I examined also, is a little different. It is clayey, with a fourth or fifth of fine rotten stone; and at two feet depth, it becomes all a rotten stone. M. de Lamont tells me, he has a kind of grape without seeds, which I did not formerly suppose to exist; but I saw at Marseilles dried raisins from Smyrna without seeds. I see in his farm at Pontac, some plants of white clover, and a good deal of yellow: also some small peach trees in the open ground. The principal English wine merchants at Bordeaux, are Jernon, Barton, Johnston, Foster, Skinner, Copinger, and M’Cartey: the chief French wine merchants, are Feger, Nerac, Bruneaux Jauge, and Du Verget. Desgrands, a wine-broker, tells me they never mix the wines of first quality: but that they mix the inferior ones to improve them. The smallest wines make the best brandy. They yield about a fifth or sixth.
May 28, 29. From Bordeaux to Blaye, the country near the river is hilly, chiefly in vines, some corn, some pasture: further out, are plains, boggy and waste. The soil, in both cases, clay and grit. Some sheep on the waste. To Etauliers, we have sometimes boggy plains, sometimes waving grounds and sandy, always poor, generally waste, in fern and furze, with some corn however, interspersed. To Mirambeau and St. Genis, it is hilly, poor, and mostly waste. There are some corn and maize however, and better trees than usual. Towards Pons, it becomes a little red, mostly rotten stone. There are vines, corn, and maize, which is up. At Pons we approach the Charente; the country becomes better, a blackish mould mixed with a rotten chalky stone: a great many vines, corn, maize, and farouche. From Lajart to Saintes and Rochefort, the soil is reddish, its foundation a chalky rock, at about a foot depth; in vines, corn, maize, clover, lucerne, and pasture. There are more and better trees than I have seen in all my journey; a great many apple and cherry trees: fine cattle and many sheep.
May 30. From Rochefort to La Rochelle, it is sometimes hilly and red, with a chalky foundation, middling good; in corn, pasture, and some waste: sometimes it is reclaimed marsh, in clover and corn, except the parts accessible to the tide, which are in wild grass. About Rochelle, it is a low plain. Towards Usseau, and halfway to Marans, level highlands, red, mixed with an equal quantity of broken chalk; mostly in vines, some corn, and pasture: then to Marans and halfway to St. Hermine, it is reclaimed marsh, dark, tolerably good, and all in pasture: there we rise to plains a little higher, red, with a chalky foundation, boundless to the eye, and altogether in corn and maize.
May 31. At St. Hermine, the country becomes very hilly, a red clay mixed with chalky stone, generally waste, in furze and broom, with some patches of corn and maize; and so it continues to Chantonay, and St. Fulgent. Through the whole of this road from Bordeaux, are frequent hedge rows, and small patches of forest wood, not good, yet better than I had seen in the preceding part of my journey. Towards Montaigu, the soil mends a little; the cultivated parts in corn and pasture, the uncultivated in broom. It is in very small enclosures of ditch and quickset. On approaching the Loire to Nantes, the country is leveller: the soil from Rochelle to this place may be said to have been sometimes red, but oftener gray, and always on a chalky foundation. The last census, of about 1770, made one hundred and twenty thousand inhabitants at Nantes. They conjecture there are now one hundred and fifty thousand, which equals it to Bordeaux.
June 1,2. The country from Nantes to L’Orient is very hilly and poor, the soil gray; nearly half is waste, in furze and broom, among which is some poor grass. The cultivated parts are in corn, some maize, a good many apple trees; no vines. All is in small enclosures of quick hedge and ditch. There are patches and hedge-rows of forest-wood, not quite deserving the name of timber. The people are mostly in villages; they eat rye-bread, and are ragged. The villages announce a general poverty, as does every other appearance. Women smite on the anvil, and work with the hoe, and cows are yoked to labor. There are great numbers of cattle, insomuch that butter is their staple. Neither asses nor mules: yet it is said that the fine mules I have met with on my journey, are raised in Poictou. There are but few chateaux here. I observe mill-ponds, and hoes with long handles. Have they not, in common with us, derived these from England, of which Bretagne is probably a colony? L’Orient is supposed to contain twenty-five thousand inhabitants. They tell me here, that to make a reasonable profit on potash and pearlash, as bought in America, the former should sell at thirty livres, the latter thirty-six livres, the quintal. Of turpentine they make no use in their vessels. Bayonne furnishes pitch enough; but tar is in demand, and ours sells well. The tower of L’Orient is sixty-five pieds above the level of the sea, one hundred and twenty pieds high, twenty-five pieds in diameter; the stairs four feet radius, and cost thirty thousand livres, besides the materials of the old tower.
June 3, 4, 5. The country and productions from L’Orient to Rennes, and from Rennes to Nantes, are precisely similar to those from Nantes to L’Orient. About Rennes, it is somewhat leveller, perhaps less poor, and almost entirely in pasture. The soil always gray. Some small, separate houses, which seem to be the residence of laborers, or very small farmers; the walls frequently of mud, and the roofs generally covered with slate. Great plantations of walnut, and frequently of pine. Some apple trees and sweet-briar still in bloom, and broom generally so. I have heard no nightingale since the last day of May. There are gates in this country made in such a manner, that the top rail of the gate overshoots backwards the hind post, so as to counterpoise the gate, and prevent its swagging.
Nantes. Vessels of eight feet draught only can come to Nantes. Those which are larger, lie at Painboeuf, ten leagues below Nantes, and five leagues above the mouth of the river. There is a continued navigation from Nantes to Paris, through the Loire, the canal de Briare and the Seine. Carolina rice is preferred to that of Lombardy for the Guinea trade, because it requires less water to boil it.
June 6, 7, 8. Nantes. Ancenis. Angers. Tours. Ascending the Loire from Nantes, the road, as far as Angers, leads over the hills, which are gray, oftener below than above mediocrity, and in corn, pasture, vines, some maize, flax, and hemp. There are no waste lands. About the limits of Bretagne and Anjou, which are between Loriottiere and St. George, the lands change for the better. Here and there, we get views of the plains on the Loire, of some extent, and good appearance, in corn and pasture. After passing Angers, the road is raised out of the reach of inundations, so as at the same time to ward them off from the interior plains. It passes generally along the river side; but sometimes leads through the plains, which, after we pass Angers, become extensive and good, in corn, pasture, some maize, hemp, flax, pease, and beans; many willows, also poplars and walnuts. The flax is near ripe. Sweet-briar in general bloom. Some broom here still, on which the cattle and sheep browse in winter and spring, when they have no other green food; and the hogs eat the blossoms and pods, in spring and summer. This blossom, though disagreeable when smelt in a small quantity, is of delicious fragrance when there is a whole field of it. There are some considerable vineyards in the river plains, just before we reach Les Trois Volets (which is at the one hundred and thirty-sixth milestone), and after that, where the hills on the left come into view, they are mostly in vines. Their soil is clayey and stony, a little reddish, and of southern aspect. The hills on the other side of the river, looking to the north, are not in vines. There is very good wine made on these hills; not equal indeed to the Bordeaux of best quality, but to that of good quality, and like it. It is a great article of exportation from Anjou and Touraine, and probably is sold abroad, under the name of Bordeaux. They are now mowing the first crop of hay. All along both hills of the Loire, is a mass of white stone, not durable, growing black with time, and so soft, that the people cut their houses out of the solid, with all the partitions, chimnies, doors, &c. The hill sides resemble cony burrows, full of inhabitants. The borders of the Loire are almost a continued village. There are many chateaux: many cattle, sheep, and horses; some asses.
Tours is at the one hundred and nineteenth mile-stone. Being desirous of inquiring here into a fact stated by Voltaire, in his Questions Encylopédiques, article Coquilles, relative to the growth of shells unconnected with animal bodies at the Chateau of Monsieur de la Sauvagiere, near Tours, I called on Monsieur Gentil, premier sécrétaire de l’ntendance, to whom the Intendant had written on my behalf, at the request of the Marquis de Chastellux.
I stated to him the fact as advanced by Voltaire, and found he was, of all men, the best to whom I could have addressed myself. He told me he had been in correspondence with Voltaire on that very subject, and was perfectly acquainted with Monsieur de la Sauvagiere, and the Faluniere where the fact is said to have taken place. It is at the Chateau de Grillemont, six leagues from Tours, on the road to Bordeaux, belonging now to Monsieur d’Orcai. He says, that De la Sauvagiere was a man of truth, and might be relied on for whatever facts he stated as of his own observation; but that he was overcharged with imagination, which, in matters of opinion and theory, often led him beyond his facts; that this feature in his character had appeared principally in what he wrote on the antiquities of Touraine; but that as to the fact in question, he believed him. That he himself, indeed, had not watched the same identical shells, as Sauvagiere had done, growing from small to great; but that he had often seen such masses of those shells of all sizes, from a point to a full size, as to carry conviction to his mind that they were in the act of growing; that he had once made a collection of shells for the Emperor’s cabinet, reserving duplicates of them for himself; and that these afforded proofs of the same fact; that he afterwards gave those duplicates to a Monsieur du Verget, a physician of Tours, of great science and candor, who was collecting on a larger scale, and who was perfectly in sentiment with Monsieur de la Sauvagiere, and not only the Faluniere, but many other places about Tours, would convince any unbiassed observer, that shells are a fruit of the earth, spontaneously produced; and he gave me a copy of De la Sauvagiere’s Recueil de Dissertations, presented him by the author, wherein is one Sur la vegetation spontanée des coquilles du Chateau des Places. So far, I repeat from him. What are we to conclude? That we have not materials enough yet, to form any conclusion. The fact stated by Sauvagiere is not against any law of nature, and is therefore possible; but it is so little analogous to her habitual processes, that, if true, it would be extraordinary: that to command our belief, therefore, there should be such a suite of observations, as that their untruth would be more extraordinary than the existence of the fact they affirm. The bark of trees, the skin of fruits and animals, the feathers of birds, receive their growth and nutriment from the internal circulation of a juice through the vessels of the individual they cover. We conclude from analogy, then, that the shells of the testaceous tribe receive also their growth from a like internal circulation. If it be urged, that this does not exclude the possibility of a like shell being produced by the passage of a fluid through the pores of the circumjacent body, whether of earth, stone, or water; I answer, that it is not within the usual economy of nature, to use two processes for one species of production. While I withhold my assent, however, from this hypothesis, I must deny it to every other I have ever seen, by which their authors pretend to account for the origin of shells in high places. Some of these are against the laws of nature, and therefore impossible; and others are built on positions more difficult to assent to, than that of De la Sauvagiere. They all suppose these shells to have covered submarine animals, and have then to answer the question, How came they fifteen thousand feet above the level of the sea? And they answer it, by demanding what cannot be conceded. One, therefore, who had rather have no opinion than a false one, will suppose this question one of those beyond the investigation of human sagacity; or wait till further and fuller observations enable him to decide it.
