Volume Ii Part 21 (1/2)

One of the skulls, which we took from the cavern of Ataruipe, has appeared in the fine work published by my old master, Blumenbach, on the varieties of the human species. The skeletons of the Indians were lost on the coast of Africa, together with a considerable part of our collections, in a s.h.i.+pwreck, in which perished our friend and fellow-traveller, Fray Juan Gonzales, the young monk of the order of Saint Francis.

We withdrew in silence from the cavern of Ataruipe. It was one of those calm and serene nights which are so common in the torrid zone.

The stars shone with a mild and planetary light. Their scintillation was scarcely sensible at the horizon, which seemed illumined by the great nebulae of the southern hemisphere. An innumerable mult.i.tude of insects spread a reddish light upon the ground, loaded with plants, and resplendent with these living and moving fires, as if the stars of the firmament had sunk down on the savannah. On quitting the cavern we stopped several times to admire the beauty of this singular scene. The odoriferous vanilla and festoons of bignonia decorated the entrance; and above, on the summit of the hill, the arrowy branches of the palm-trees waved murmuring in the air. We descended towards the river, to take the road to the mission, where we arrived late in the night.

Our imagination was struck by all we had just seen. Occupied continually by the present, in a country where the traveller is tempted to regard human society as a new inst.i.tution, he is more powerfully interested by remembrances of times past. These remembrances were not indeed of a distant date; but in all that is monumental antiquity is a relative idea, and we easily confound what is ancient with what is obscure and problematic. The Egyptians considered the historical remembrances of the Greeks as very recent.

If the Chinese, or, as they prefer calling themselves, the inhabitants of the Celestial Empire, could have communicated with the priests of Heliopolis, they would have smiled at those pretensions of the Egyptians to antiquity. Contrasts not less striking are found in the north of Europe and of Asia, in the New World, and in every region where the human race has not preserved a long consciousness of itself.

The migration of the Toltecs, the most ancient historical event on the tableland of Mexico, dates only in the sixth century of our era. The introduction of a good system of intercalation, and the reform of the calendars, the indispensable basis of an accurate chronology, took place in the year 1091. These epochs, which to us appear so modern, fall on fabulous times, when we reflect on the history of our species between the banks of the Orinoco and the Amazon. We there see symbolic figures sculptured on the rocks, but no tradition throws light upon their origin. In the hot part of Guiana we can go back only to the period when the Castilian and Portuguese conquerors, and more recently peaceful monks, penetrated amid so many barbarous nations.

It appears that to the north of the Cataracts, in the strait of Baraguan, there are caverns filled with bones, similar to those I have just described: but I was informed of this fact only after my return; our Indian pilots did not mention it when we landed at the strait.

These tombs no doubt have given rise to a fable of the Ottomacs, according to which the granitic and solitary rocks of Baraguan, the forms of which are very singular, are regarded as the grandfathers, the ancient chiefs of the tribe. The custom of separating the flesh from the bones, very anciently practised by the Ma.s.sagetes, is still known among several hordes of the Orinoco. It is even a.s.serted, and with some probability, that the Guaraons plunge their dead bodies under water enveloped in nets; and that the small caribe-fishes, of which we saw everywhere an innumerable quant.i.ty, devour in a few days the muscular flesh, and thus prepare the skeleton. It may be supposed that this operation can be practised only in places where crocodiles are not common. Some tribes, for instance the Tamanacs, are accustomed to lay waste the fields of a deceased relative, and cut down the trees which he has planted. They say that the sight of objects which belonged to their relation makes them melancholy. They like better to efface than to preserve remembrances. These effects of Indian sensibility are very detrimental to agriculture, and the monks oppose with energy these superst.i.tious practices, to which the natives converted to Christianity still adhere in the missions.

The tombs of the Indians of the Orinoco have not been very closely examined, because they do not contain valuable articles like those of Peru; and even on the spot no faith is now lent to the chimerical ideas, which were heretofore formed of the wealth of the ancient inhabitants of El Dorado. The thirst of gold everywhere precedes the desire of instruction, and a taste for researches into antiquity; in all the mountainous part of South America, from Merida and Santa Martha to the table-lands of Quito and Upper Peru, the labours of absolute mining have been undertaken to discover tombs, or, as the Creoles say, employing a word altered from the Inca language, guacas.

When in Peru, at Mancichi, I went into the guaca from which, in the sixteenth century, ma.s.ses of gold of great value were extracted. No trace of the precious metals has been found in the caverns which have served the natives of Guiana for ages as sepulchres. This circ.u.mstance proves that even at the period when the Caribs, and other travelling nations, made incursions to the south-west, gold had flowed in very small quant.i.ties from the mountains of Peru towards the eastern plains.

Wherever the granitic rocks do not present any of those large cavities caused by their decomposition, or by an acc.u.mulation of their blocks, the Indians deposit their dead in the earth. The hammock (chinchorro), a kind of net in which the deceased had reposed during his life, serves for a coffin. This net is fastened tight round the body, a hole is dug in the hut, and there the body is laid. This is the most usual method, according to the account of the missionary Gili, and it accords with what I myself learned from Father Zea. I do not believe that there exists one tumulus in Guiana, not even in the plains of the Ca.s.siquiare and the Essequibo. Some, however, are to be met with in the savannahs of Varinas, as in Canada, to the west of the Alleghenies.* (* Mummies and skeletons contained in baskets were recently discovered in a cavern in the United States. It is believed they belong to a race of men a.n.a.logous to that of the Sandwich Islands. The description of these tombs has some similitude with that of the tombs of Ataruipe.) It seems remarkable enough that, notwithstanding the extreme abundance of wood in those countries, the natives of the Orinoco were as little accustomed as the ancient Scythians to burn the dead. Sometimes they formed funeral piles for that purpose; but only after a battle, when the number of the dead was considerable. In 1748, the Parecas burned not only the bodies of their enemies, the Tamanacs, but also those of their own people who fell on the field of battle. The Indians of South America, like all nations in a state of nature, are strongly attached to the spots where the bones of their fathers repose. This feeling, which a great writer has beautifully painted in the episode of Atala, is cherished in all its primitive ardour by the Chinese. These people among whom everything is the produce of art, or rather of the most ancient civilization, do not change their dwelling without carrying along with them the bones of their ancestors. Coffins are seen deposited on the banks of great rivers, to be transported, with the furniture of the family, to a remote province. These removals of bones, heretofore more common among the savages of North America, are not practised among the tribes of Guiana; but these are not nomad, like nations who live exclusively by hunting.

We stayed at the mission of Atures only during the time necessary for pa.s.sing the canoe through the Great Cataract. The bottom of our frail bark had become so thin that it required great care to prevent it from splitting. We took leave of the missionary, Bernardo Zea, who remained at Atures, after having accompanied us during two months, and shared all our sufferings. This poor monk still continued to have fits of tertian ague; they had become to him an habitual evil, to which he paid little attention. Other fevers of a more fatal kind prevailed at Atures on our second visit. The greater part of the Indians could not leave their hammocks, and we were obliged to send in search of ca.s.sava-bread, the most indispensable food of the country, to the independent but neighbouring tribe of the Piraoas. We had hitherto escaped these malignant fevers, which I believe to be always contagious.

We ventured to pa.s.s in our canoe through the latter half of the Raudal of Atures. We landed here and there, to climb upon the rocks, which like narrow dikes joined the islands to one another. Sometimes the waters force their way over the dikes, sometimes they fall within them with a hollow noise. A considerable portion of the Orinoco was dry, because the river had found an issue by subterraneous caverns. In these solitary haunts the rock-manakin with gilded plumage (Pipra rupicola), one of the most beautiful birds of the tropics, builds its nest. The Raudalito of Carucari is caused by an acc.u.mulation of enormous blocks of granite, several of which are spheroids of five or six feet in diameter, and they are piled together in such a manner, as to form s.p.a.cious caverns. We entered one of these caverns to gather the confervas that were spread over the clefts and humid sides of the rock. This spot displayed one of the most extraordinary scenes of nature that we had contemplated on the banks of the Orinoco. The river rolled its waters turbulently over our heads. It seemed like the sea das.h.i.+ng against reefs of rocks; but at the entrance of the cavern we could remain dry beneath a large sheet of water that precipitated itself in an arch from above the barrier. In other cavities, deeper, but less s.p.a.cious, the rock was pierced by the effect of successive filtrations. We saw columns of water, eight or nine inches broad, descending from the top of the vault, and finding an issue by clefts, that seemed to communicate at great distances with each other.

The cascades of Europe, forming only one fall, or several falls close to each other, can never produce such variety in the s.h.i.+fting landscape. This variety is peculiar to rapids, to a succession of small cataracts several miles in length, to rivers that force their way across rocky dikes and acc.u.mulated blocks of granite. We had the opportunity of viewing this extraordinary sight longer than we wished.

Our boat was to coast the eastern bank of a narrow island, and to take us in again after a long circuit. We pa.s.sed an hour and a half in vain expectation of it. Night approached, and with it a tremendous storm.

It rained with violence. We began to fear that our frail bark had been wrecked against the rocks, and that the Indians, conformably to their habitual indifference for the evils of others, had returned tranquilly to the mission. There were only three of us: we were completely wet, and uneasy respecting the fate of our boat: it appeared far from agreeable to pa.s.s, without sleep, a long night of the torrid zone amid the noise of the Raudales. M. Bonpland proposed to leave me in the island with Don Nicolas Soto, and to swim across the branches of the river that are separated by the granitic dikes. He hoped to reach the forest, and seek a.s.sistance at Atures from Father Zea. We dissuaded him with difficulty from undertaking this hazardous enterprise. He knew little of the labyrinth of small channels, into which the Orinoco is divided. Most of them have strong whirlpools, and what pa.s.sed before our eyes while we were deliberating on our situation, proved sufficiently that the natives had deceived us respecting the absence of crocodiles in the cataracts. The little monkeys which we had carried along with us for months were deposited on the point of our island. Wet by the rains and sensible of the least lowering of the temperature, these delicate animals sent forth plaintive cries, and attracted to the spot two crocodiles, the size and leaden colour of which denoted their great age. Their unexpected appearance made us reflect on the danger we had incurred by bathing, at our first pa.s.sing by the mission of Atures, in the middle of the Raudal. After long waiting, the Indians at length arrived at the close of day. The natural coffer-dam by which they had endeavoured to descend in order to make the circuit of the island, had become impa.s.sable owing to the shallowness of the water. The pilot sought long for a more accessible pa.s.sage in this labyrinth of rocks and islands. Happily our canoe was not damaged and in less than half an hour our instruments, provision, and animals, were embarked.

We pursued our course during a part of the night, to pitch our tent again in the island of Panumana. We recognized with pleasure the spots where we had botanized when going up the Orinoco. We examined once more on the beach of Guachaco that small formation of sandstone, which reposes directly on granite. Its position is the same as that of the sandstone which Burckhardt observed at the entrance of Nubia, superimposed on the granite of Syene. We pa.s.sed, without visiting it, the new mission of San Borga, where (as we learned with regret a few days after) the little colony of Guahibos had fled al monte, from the chimerical fear that we should carry them off; to sell them as poitos, or slaves. After having pa.s.sed the rapids of Tabaje, and the Raudal of Cariven, near the mouth of the great Rio Meta, we arrived without accident at Carichana. The missionary received us with that kind hospitality which he extended to us on our first pa.s.sage. The sky was unfavourable for astronomical observations; we had obtained some new ones in the two Great Cataracts; but thence, as far as the mouth of the Apure, we were obliged to renounce the attempt. M. Bonpland had the satisfaction at Carichana of dissecting a manatee more than nine feet long. It was a female, and the flesh appeared to us not unsavoury. I have spoken in another place of the manner of catching this herbivorous cetacea. The Piraoas, some families of whom inhabit the mission of Carichana, detest this animal to such a degree, that they hid themselves, to avoid being obliged to touch it, whilst it was being conveyed to our hut. They said that the people of their tribe die infallibly when they eat of it. This prejudice is the more singular, as the neighbours of the Piraoas, the Guamos and the Ottomacs, are very fond of the flesh of the manatee. The flesh of the crocodile is also an object of horror to some tribes, and of predilection to others.

The island of Cuba furnishes a fact little known in the history of the manatee. South of the port of Xagua, several miles from the coast, there are springs of fresh water in the middle of the sea. They are supposed to be owing to a hydrostatic pressure existing in subterraneous channels, communicating with the lofty mountains of Trinidad. Small vessels sometimes take in water there; and, what is well worthy of observation, large manatees remain habitually in those spots. I have already called the attention of naturalists to the crocodiles which advance from the mouth of rivers far into the sea.

a.n.a.logous circ.u.mstances may have caused, in the ancient catastrophes of our planet, that singular mixture of pelagian and fluviatile bones and petrifactions, which is observed in some rocks of recent formation.

Our stay at Carichana was very useful in recruiting our strength after our fatigues. M. Bonpland bore with him the germs of a cruel malady; he needed repose; but as the delta of the tributary streams included between the h.o.r.eda and Paruasi is covered with a rich vegetation, he made long herbalizations, and was wet through several times in a day.

We found, fortunately, in the house of the missionary, the most attentive care; we were supplied with bread made of maize flour, and even with milk. The cows yield milk plentifully enough in the lower regions of the torrid zone, wherever good pasturage is found. I call attention to this fact, because local circ.u.mstances have spread through the Indian Archipelago the prejudice of considering hot climates as repugnant to the secretion of milk. We may conceive the indifference of the inhabitants of the New World for a milk diet, the country having been originally dest.i.tute of animals capable of furnis.h.i.+ng it*; (* The reindeer are not domesticated in Greenland as they are in Lapland; and the Esquimaux care little for their milk. The bisons taken very young accustom themselves, on the west of the Alleghenies, to graze with herds of European cows. The females in some districts of India yield a little milk, but the natives have never thought of milking them. What is the origin of that fabulous story related by Gomara (chapter 43 page 36) according to which the first Spanish navigators saw, on the coast of South Carolina, stags led to the savannahs by herdsmen? The female bisons, according to Mr.

Buchanan and the philosophical historian of the Indian Archipelago, Mr. Crawford, yield more milk than common cows.) but how can we avoid being astonished at this indifference in the immense Chinese population, living in great part beyond the tropics, and in the same lat.i.tude with the nomad and pastoral tribes of central Asia? If the Chinese have ever been a pastoral people, how have they lost the tastes and habits so intimately connected with that state, which precedes agricultural inst.i.tutions? These questions are interesting with respect both to the history of the nations of oriental Asia, and to the ancient communications that are supposed to have existed between that part of the world and the north of Mexico.

We went down the Orinoco in two days, from Carichana to the mission of Uruana, after having again pa.s.sed the celebrated strait of Baraguan.

We stopped several times to determine the velocity of the river, and its temperature at the surface, which was 27.4 degrees. The velocity was found to be two feet in a second (sixty-two toises in 3 minutes 6 seconds) in places where the bed of the Orinoco was more than twelve thousand feet broad, and from ten to twelve fathoms deep. The slope of the river is in fact extremely gentle from the Great Cataracts to Angostura; and, if a barometric measurement were wanting, the difference of height might be determined by approximation, by measuring from time to time the velocity of the stream, and the extent of the section in breadth and depth. We had some observations of the stars at Uruana. I found the lat.i.tude of the mission to be 7 degrees 8 minutes; but the results from different stars left a doubt of more than 1 minute. The stratum of mosquitos, which hovered over the ground, was so thick that I could not succeed in rectifying properly the artificial horizon. I tormented myself in vain; and regretted that I was not provided with a mercurial horizon. On the 7th of June, good absolute alt.i.tudes of the sun gave me 69 degrees 40 minutes for the longitude. We had advanced from Esmeralda 1 degree 17 minutes toward the west, and this chronometric determination merits entire confidence on account of the double observations, made in going and returning, at the Great Cataracts, and at the confluence of the Atabapo and of the Apure.

The situation of the mission of Uruana is extremely picturesque. The little Indian village stands at the foot of a lofty granitic mountain.

Rocks everywhere appear in the form of pillars above the forest, rising higher than the tops of the tallest trees. The aspect of the Orinoco is nowhere more majestic than when viewed from the hut of the missionary, Fray Ramon Bueno. It is more than two thousand six hundred toises broad, and it runs without any winding, like a vast ca.n.a.l, straight toward the east. Two long and narrow islands (Isla de Uruana and Isla vieja de la Manteca) contribute to give extent to the bed of the river; the two banks are parallel, and we cannot call it divided into different branches. The mission is inhabited by the Ottomacs, a tribe in the rudest state, and presenting one of the most extraordinary physiological phenomena. They eat earth; that is, they swallow every day, during several months, very considerable quant.i.ties, to appease hunger, and this practice does not appear to have any injurious effect on their health. Though we could stay only one day at Uruana, this short s.p.a.ce of time sufficed to make us acquainted with the preparation of the poya, or b.a.l.l.s of earth. I also found some traces of this vitiated appet.i.te among the Guamos; and between the confluence of the Meta and the Apure, where everybody speaks of dirt-eating as of a thing anciently known. I shall here confine myself to an account of what we ourselves saw or heard from the missionary, who had been doomed to live for twelve years among the savage and turbulent tribe of the Ottomacs.

The inhabitants of Uruana belong to those nations of the savannahs called wandering Indians (Indios andantes) who, more difficult to civilize than the nations of the forest (Indios del monte), have a decided aversion to cultivate the land, and live almost exclusively by hunting and fis.h.i.+ng. They are men of very robust const.i.tution; but ill-looking, savage, vindictive, and pa.s.sionately fond of fermented liquors. They are omnivorous animals in the highest degree; and therefore the other Indians, who consider them as barbarians, have a common saying, nothing is so loathsome but that an Ottomac will eat it. While the waters of the Orinoco and its tributary streams are low, the Ottomacs subsist on fish and turtles. The former they kill with surprising dexterity, by shooting them with an arrow when they appear at the surface of the water. When the rivers swell fis.h.i.+ng almost entirely ceases.* (* In South America, as in Egypt and Nubia, the swelling of the rivers, which occurs periodically in every part of the torrid zone, is erroneously attributed to the melting of the snows.) It is then very difficult to procure fish, which often fails the poor missionaries, on fast-days as well as flesh-days, though all the young Indians are under the obligation of fis.h.i.+ng for the convent. During the period of these inundations, which last two or three months, the Ottomacs swallow a prodigious quant.i.ty of earth. We found heaps of earth-b.a.l.l.s in their huts, piled up in pyramids three or four feet high. These b.a.l.l.s were five or six inches in diameter. The earth which the Ottomacs eat is a very fine and unctuous clay of a yellowish grey colour; and, when being slightly baked at the fire, the hardened crust has a tint inclining to red, owing to the oxide of iron which is mingled with it. We brought away some of this earth, which we took from the winter-provision of the Indians; and it is a mistake to suppose that it is steat.i.tic, and that it contains magnesia. Vauquelin did not discover any traces of that substance in it but he found that it contained more silex than alumina, and three or four per cent of lime.

The Ottomacs do not eat every kind of clay indifferently; they choose the alluvial beds or strata, which contain the most unctuous earth, and the smoothest to the touch. I inquired of the missionary whether the moistened clay were made to undergo that peculiar decomposition which is indicated by a disengagement of carbonic acid and sulphuretted hydrogen, and which is designated in every language by the term of putrefaction; but he a.s.sured us that the natives neither cause the clay to rot, nor do they mingle it with flour of maize, oil of turtle's eggs, or fat of the crocodile. We ourselves examined, both at the Orinoco and after our return to Paris, the b.a.l.l.s of earth which we brought away with us, and found no trace of the mixture of any organic substance, whether oily or farinaceous. The savage regards every thing as nouris.h.i.+ng that appeases hunger: when, therefore, you inquire of an Ottomac on what he subsists during the two months when the river is at its highest flood he shows you his b.a.l.l.s of clayey earth. This he calls his princ.i.p.al food at the period when he can seldom procure a lizard, a root of fern, or a dead fish swimming at the surface of the water. If necessity force the Indians to eat earth during two months (and from three quarters to five quarters of a pound in twenty-four hours), he eats it from choice during the rest of the year. Every day in the season of drought, when fis.h.i.+ng is most abundant, he sc.r.a.pes his b.a.l.l.s of poya, and mingles a little clay with his other aliment. It is most surprising that the Ottomacs do not become lean by swallowing such quant.i.ties of earth: they are, on the contrary, extremely robust. The missionary Fray Ramon Bueno a.s.serts that he never remarked any alteration in the health of the natives at the period of the great risings of the Orinoco.

The Ottomacs during some months eat daily three-quarters of a pound of clay slightly hardened by fire, but which they moisten before swallowing it. It has not been possible to verify hitherto with precision how much nutritious vegetable or animal matter they take in a week at the same time; but they attribute the sensation of satiety which they feel to the clay, and not to the wretched aliments which they take with it occasionally.

No physiological phenomenon being entirely insulated, it may be interesting to examine several a.n.a.logous phenomena, which I have been able to collect. I observed everywhere within the torrid zone, in a great number of individuals, children, women, and sometimes even full-grown men, an inordinate and almost irresistible desire of swallowing earth; not an alkaline or calcareous earth to neutralize (as it is said) acid juices, but a fat clay, unctuous, and exhaling a strong smell. It is often found necessary to tie the children's hands or to confine them to prevent them eating earth when the rain ceases to fall. At the village of Banco, on the bank of the river Magdalena, I saw the Indian women who make pottery continually swallowing great pieces of clay. These women were not in a state of pregnancy; and they affirmed that earth is an aliment which they do not find hurtful. In other American tribes, people soon fall sick, and waste away, when they yield too much to this mania of eating earth. We found at the mission of San Borja an Indian child of the Guahiba nation, who was as thin as a skeleton. The mother informed us that the little girl was reduced to this lamentable state of atrophy in consequence of a disordered appet.i.te, she having refused during four months to take almost any other food than clay. Yet San Borja is only twenty-five leagues distant from the mission of Uruana, inhabited by that tribe of the Ottomacs, who, from the effect no doubt of a habit progressively acquired, swallow the poya without experiencing any pernicious effects. Father Gumilla a.s.serts that the Ottomacs take as an aperient, oil, or rather the melted fat of the crocodile, when they feel any gastric obstructions; but the missionary whom we found among them was little disposed to confirm this a.s.sertion. It may be asked, why the mania of eating earth is much more rare in the frigid and temperate than in the torrid zones; and why in Europe it is found only among women in a state of pregnancy, and sickly children. This difference between hot and temperate climates arises perhaps only from the inert state of the functions of the stomach caused by strong cutaneous perspiration. It has been supposed to be observed that the inordinate taste for eating earth augments among the African slaves, and becomes more pernicious when they are restricted to a regimen purely vegetable and deprived of spirituous liquors.

The negroes on the coast of Guinea delight in eating a yellowish earth, which they call caouac. The slaves who are taken to America endeavour to indulge in this habit; but it proves detrimental to their health. They say that the earth of the West Indies is not so easy of digestion as that of their country. Thibaut de Chanvalon, in his Voyage to Martinico, expresses himself very judiciously on this pathological phenomenon. ”Another cause,” he says, ”of this pain in the stomach is that several of the negroes, who come from the coast of Guinea, eat earth; not from a depraved taste, or in consequence of disease, but from a habit contracted at home in Africa, where they eat, they say, a particular earth, the taste of which they find agreeable, without suffering any inconvenience. They seek in our islands for the earth most similar to this, and prefer a yellowish red volcanic tufa. It is sold secretly in our public markets; but this is an abuse which the police ought to correct. The negroes who have this habit are so fond of caouac, that no chastis.e.m.e.nt will prevent their eating it.”

In the Indian Archipelago, at the island of Java, Labillardiere saw, between Surabaya and Samarang, little square and reddish cakes exposed for sale. These cakes called tanaampo, were cakes of clay, slightly baked, which the natives eat with relish. The attention of physiologists, since my return from the Orinoco, having been powerfully directed to these phenomena of geophagy, M. Leschenault (one of the naturalists of the expedition to the Antarctic regions under the command of captain Baudin) has published some curious details on the tanaampo, or ampo, of the Javanese. ”The reddish and somewhat ferruginous clay,” he says ”which the inhabitants of Java are fond of eating occasionally, is spread on a plate of iron, and baked, after having been rolled into little cylinders in the form of the bark of cinnamon. In this state it takes the name of ampo, and is sold in the public markets. This clay has a peculiar taste, which is owing to the baking: it is very absorbent, and adheres to the tongue, which it dries. In general it is only the Javanese women who eat the ampo, either in the time of pregnancy, or in order to grow thin; the absence of plumpness being there regarded as a kind of beauty. The use of this earth is fatal to health; the women lose their appet.i.te imperceptibly, and take only with relish a very small quant.i.ty of food; but the desire of becoming thin, and of preserving a slender shape, induces them to brave these dangers, and maintains the credit of the ampo.”

The savage inhabitants of New Caledonia also, to appease their hunger in times of scarcity, eat great pieces of a friable Lapis ollaris.
