I HAVE stated in the preface to the first Edition of this work, and in the Zoology of the Voyage of the Beagle, that it was in con- sequence of a wish expressed by Captain Fitz Eoy, of having some scientific person on board, accompanied by an offer from him of giving up part of his own accommodations, that I volunteered my services, which received, through the kindness of the hydro- grapher, Captain Beaufort, the sanction of the Lords of the Admiralty. As I feel that the opportunities which I enjoyed of studying the Natural History of the different countries we visited, have been wholly due to Captain Fitz Eoy, I hope I may here be permitted to repeat my expression of gratitude to him; and to add that, during the five years we were together, I received from him the most cordial friendship and steady assistance. Both to Captain Fitz Eoy and to all the Officers of the Beagle * I shall ever feel most thankful for the undeviating kindness with which I was treated during our long voyage. This volume contains, in the form of a Journal, a history of our voyage, and a sketch of those observations in Natural History and Geology, which I think will possess some interest for the general reader. I have in this edition largely condensed and corrected some parts, and have added a little to others, in order to render the volume more fitted for popular reading; but I trust that naturalists will remember, that they must refer for details to the larger publications, which comprise the scientific results of the Expedition. The Zoology of the Voyage of the Beagle includes an * I must take this opportunity of returning my sincere thanks to Mr. Bynoc, the surgeon of the Beagle, for his very kind attention to me when I was ill at Valparaiso. Vlii PREFACE. account of the Fossil Mammalia, by Professor Owen ; of the Living Mammalia, by Mr. Waterhouse ; of the Birds, by Mr. Gould; of the Fish, by the Eev. L. Jenyns ; and of the Eeptiles, by Mr. Bell. I have appended to the descriptions of each species an account of its habits and range. These works, -which I owe to the high talents and disinterested zeal of the above distinguished authors, could not have been undertaken, had it not been for the liberality of the Lords Commissioners of Her Majesty's Treasury, who, through the representation of the Eight Honourable the Chancellor of the Ex- chequer, have been pleased to grant a sum of one thousand pounds towards defraying part of the expenses of publication. I have myself published separate volumes on the ' Structure and Distribution of Coral Eeefs;' on the 'Volcanic Islands visited during the Voyage of the Beagle ; ' and on the ' Geology of South America.' The sixth volume of the 'Geological Transactions' contains two papers of mine on the Erratic Boulders and Volcanic Phenomena of South America. Messrs. "Waterhouse, Walker, Newman, and White, have published several able papers on the Insects which were collected, and I trust that many others will hereafter follow. The plants from the southern parts of America will be given by Dr. J. Hooker, in his great work on the Botany of the Southern Hemisphere. The Flora of the Galapagos Archi- pelago is the subject of a separate memoir by him, in the ' Linneau Transactions.' The Eeverend Professor Henslow has published a list of the plants collected by me at the Keeling Islands; and the Eeverend J. M. Berkeley has described my cryptogamic plants. I shall have the pleasure of acknowledging the great assistance which I have received from several other naturalists, in the course of this and my other works ; but I must be here allowed to return my most sincere thanks to the Eeverend Professor Henslow, who, when I was an undergraduate at Cambridge, was one chief means of giving me a taste for Natural History, — who, during my absence, took charge of the collections I sent home, and by his correspond- ence directed my endeavours, — and who, since my return, has constantly rendered me every assistance which the kindest friend could offer.

ST. JAGO — CAPE DE YERD ISLANDS. AFTER having been twice driven back by heavy south-western gales, Her Majesty's ship Beagle, a ten-gun brig, under the com- mand of Captain Fitz Koy, E.N., sailed from Devonport on the 27th of December, 1831. The object of the expedition was to com- plete the survey of Patagonia and Tierra del Fuego, commenced under Captain King in 1826 fo 1830 — to survey the shores of Chile, Peru, and of some islands in the Pacific — and to carry a chain of chronometrical measurements round the World. On the 6th of January we reached Teneriffe, but were prevented landing, by fears of our bringing the cholera : the next morning we saw the sun rise behind the rugged outline of the Grand Canary island, and sud- denly illumine the Peak of Teneriffe, whilst the lower parts were veiled in fleecy clouds. This was the first of many delightful days never to be forgotten. On the 16th of January, 1832, we anchored at Porto Praya, in St. Jago, the chief island of the Cape de Verd archipelago. The neighbourhood of Porto Praya, viewed from the sea, wears a desolate aspect. The volcanic fires of a past age, and the scorching heat of a tropical sun, have in most places rendered the soil unfit for vegetation. The country rises in successive steps of table-land, interspersed •with some truncate conical hills, and the horizon is bounded by an irregular chain of more lofty mountains. The scene, B 2 ST. JAGO — CAPE DE VEED ISLANDS. [CHAI\ I. as beheld through the hazy atmosphere of this climate, is one of great interest ; if, indeed, a person, fresh from sea, and who has just walked, for the first time, in a grove of cocoa-nut trees, can be a judge of anything but his own happiness. The island would generally be considered as very uninteresting; but to any one accustomed only to an English landscape, the novel aspect of an utterly sterile land possesses a grandeur which more vegetation might spoil. A single green leaf can scarcely be discovered over wide tracts of the lava plains ; yet flocks of goats, together with a few cows, contrive to exist. It rains very seldom, but during a short portion of the year heavy torrents fall, and immediately afterwards a light vegetation springs out of every crevice. This soon withers ; and upon such naturally formed hay the animals live. It had not now rained for an entire year. When the island was discovered, the immediate neighbourhood of JPorto Praya was clothed with trees,* the reckless destruction of which has caused here, as at St. Helena, and at some of the Canary islands almost entire sterility. The broad, flat-bottomed valleys, many of which serve during a few days only in the season as watercourses, are clothed with thickets of leafless bushes. Few living creatures inhabit these valleys. The commonest bird is a kingfisher (Dacelo lagonesis), which tamely sits on the branches of the castor-oil plant, and thence darts on grass- hoppers and lizards. It is brightly coloured, but not so beaiitiful as the European species : in its flight, manners, and place of habi- tation, which is generally in the driest valley, there is also a wide difference. One day, two of the officers and myself rode to Eibeira Grande, a village a few miles eastward of Porto Praya. Until we reached the valley of St. Martin, the country presented its usual dull brown appearance ; but here, a very small rill of water produces a most refreshing margin of luxuriant vegetation. In the course of an hour we arrived at Eibeira Grande, and were surprised at the sight of a large ruined fort and cathedral. This little town, before its harbour was filled up, was the principal place in the island : it now presents a melancholy, but very picturesque appearance. Having procured a black Padre for a guide, and a Spaniard who had served in the Peninsular war as an interpreter, we visited a collection of buildings, of which an ancient church formed the principal part. It is here * I state this on the authority of Dr. E. Dieffenbach, in his German translation of the first edition of this Journal. 1832.] IIIBKIL'A GRANDE— ST. DOMINGO. 3 the governors and captain-generals of the islands have been buried. Some of the tombstones recorded dates of the sixteenth century.* The heraldic ornaments were the only things in this retired place that reminded ITS of Europe. The church or chapel formed one side of a quadrangle, in the middle of which a large clump of bananas were growing. On another side was a hospital, containing about a dozen miserable-looking inmates. We returned to the Venda to eat our dinners. A. considerable number of men, women, and children, all as black as jet, collected to watch us. Our companions were extremely merry ; and every- thing we said or did was followed by their hearty laughter. Before leaving the town we visited the cathedral. It does not appear so rich as the smaller church, but boasts of a little organ, which sent forth singularly inharmonious cries. We presented the black priest with a few shillings, and the Spaniard, patting him on the head, said, with much candour, he thought his colour made no great difference. We then returned, as fast as the ponies would go, to Porto Praya. Another day we rode to the village of St. Domingo, situated near the centre of the island. On a small plain which we crossed, a few stunted acacias were growing ; their tops had been bent by the steady trade-wind, in a singular manner — some of them even at right angles to their trunks. The direction of the branches was exactly N.E. by N., and S.W. by S., and these natural vanes must indicate the prevailing direction of the force of the trade-wind. The travelling had made so little impression on the barren soil, that we here missed our track, and took that to Fuentes. This wo did not find out till we arrived there; and we were afterwards glad of our mistake. Fuentes is a pretty village, with a small stream; and everything appeared to prosper well, excepting, indeed, that which ought to do so most — its inhabitants. The black children, completely naked, and looking very wretched, were carrying bundles of firewood half as big as their own bodies. Near Fuentes we saw a large flock of guinea-fowl — probably fifty or sixty in number. They were extremely wary, and could not be approached. They avoided us, like partridges on a rainy day in September, running with their heads cocked up; and if pursued, they readily took to the wing. * The Cape tie Verd Islands were discovered in 1449. There was a tombstone of a bishop with the date of 1571; and a crest of a hand and dagger, dated 1497. 4 ST. JAGO — CAPE DE VERD ISLANDS. [CHAP. i. The scenery of St. Domingo possesses a beauty totally unex- pected, from the prevalent gloomy character of the rest of the island. The village is situated at the bottom of a valley, bounded by lofty and jagged walls of stratified lava. The black rocks afford a most striking contrast with the bright green vegetation , which follows the banks of a little stream of clear water. It happened to be a grand feast-day, and the village was full of people. On our return we overtook a party of about twenty young black girls, dressed in excellent taste; their black skins and snow-white linen being set off by coloured turbans and large shawls. As soon as we approached near, they suddenly all turned round, and covering the path with their shawls, sung with great energy a wild song, beating time with their hands upon their legs. We threw them some vintems, which were received with screams of laughter, and we left them redoubling the noise of their song. One morning the view was singularly clear ; the distant moun- tains being projected with the sharpest outline, on a heavy bank of dark blue clouds. Judging from the appearance, and from similar cases in England, I supposed that the air was saturated with moisture. The fact, however, turned out quite the contrary. The hygrometer gave a difference of 29-6 degrees, between the temperature of the air, and the point at which dew was pre- cipitated. This difference was nearly double that which I had observed on the previous mornings. This unusual degree of atmospheric dryness was accompanied by continual flashes of lightning. Is it not an uncommon case, thus to find a remark- able degree of aerial transparency with such a state of weather ? Generally the atmosphere is hazy; and this is caused by the falling of impalpably fine dust, which was found to have slightly injured the astronomical instruments. The morning before we anchored at Porto Praya, I collected a little packet of this brown- coloured fine dust, which appeared to have been filtered from the wind by the gauze of the vane at the mast-head. Mr. Lyell has also given me four packets of dust which fell on a vessel a few hundred miles northward of these islands. Professor Ehrenberg* * I must take this opportunity of acknowledging the great kindness with which this illustrious naturalist has examined many of my specimens. I have sent (June, 1845) a full account of the falling of this dust to the Geological Society. ,. 1832.] ATMOSPHERIC DUST WITH INFUSORIA. 5 finds that this dust consists in great part of infusoria with siliceous shields, and of the siliceous tissue of plants. In five little packets which I sent him, he has ascertained no less than sixty-seven different organic forms ! The infusoria, with the exception of two marine species, are all inhabitants of fresh-water. I have found no less than fifteen different accounts of dust having fallen on vessels when far out in the Atlantic. From the direction of the wind whenever it has fallen, and from its having always fallen during those mouths when the harmattan is known to raise clouds of dust high into the atmosphere, we may feel sure that it all comes from Africa. Jt is, however, a very singular fact, that, although Professor Ehrenberg knows many species of infusoria peculiar to Africa, he finds none of these in the dust which I sent him : on the other hand, he finds in it two species which hitherto he knows as living only in South America. The dust falls in such quantities as to dirty everything on board, and to hurt people's eyes ; vessels even have run on shore owing to the obscurity of the atmosphere. It has often fallen on ships when several hundred, and even more than a thousand miles from the coast of Africa, and at points sixteen hundred miles distant in a north and south direction. In some dust which was collected on a vessel three hundred miles from tho laud, I was much surprised to find particles of stone above the thousandth of an inch square, mixed with finer matter. After this fact one need not be surprised at the diffusion of the far lighter and smaller sporules of cryptogamic plants. The geology of this island is the most interesting part of its natural history. On entering the harbour, a perfectly horizontal white band in the face of the sea cliff, may be seen running for some miles along the coast, and at the height of about forty-five feet above the water. Upon examination, this white stratum is found to consist of calcareous matter, with numerous shells embedded, most or all of which now exist on the neighbouring coast. It rests on ancient volcanic rocks, and has been covered by a stream of basalt, which must have entered the sea when the white shelly bed was lying at the bottom. It is interesting to trace the changes, produced by the heat of the overlying lava, on the friable mass, which in parts has been converted into a crystalline limestone, and in other parts into a compact spotted stone. Where the lime has been caught up by the scoriaceous fragments of the lower surface of the stream, it is converted into groups of beautifully radiated 6 ST. JAGO— CAPE DE VERD tSLAKDS. [CHAP. i. fibres resembling arragonite. The beds of lava rise in successive gently-sloping plains, towards the interior, whence the deluges of melted stone have originally proceeded. Within historical times, no signs of volcanic activity have, I believe, been manifested in any part of St. Jago. Even the form of a crater can but rarely be discovered on the summits of the many red cindery hills ; yet the more recent streams can be distinguished on the coast, forming lines of cliffs of less height, but stretching out in advance of those belonging to an older series : the height of the cliffs thus affording a rude measure of the age of the streams. During our stay, I observed the habits of some marine animals. A large Aplysia is very common. This sea-slug is about five inches long ; and is of a dirty yellowish colour, veined with purple. On each side of the lower surface, or foot, there is a broad membrane, which appears sometimes to act as a ventilator, in causing a current of water to flow over the dorsal branchia) or lungs. It feeds on the delicate sea-weeds which grow among the stones in muddy and shallow water ; and I found in its stomach several small pebbles, as in the gizzard of a bird. This slug, when disturbed, emits a very fine purplish-red fluid, which stains the water for the space of a foot around. Besides this means of defence, an acrid secretion, which is spread over its body, causes a sharp, stinging sensation, similar to that produced by the Physalia, or Portuguese man-of- war. I was much interested, on several occasions, by watching the habits of an Octopus, or cuttle-fish. Although common in the pools of water left by the retiring tide, these animals were not easily caught. By means of their long arms and suckers, they could drag their bodies into very narrow crevices ; and when thus fixed, it required great force to remove them. At other times they darted tail first, with the rapidity of an arrow, from one side of the pool to the other, at the same instant discolouring the water with a dark chestnut-brown ink. These animals also escape detection by a very extraordinary, chameleon-like power of changing their colour. They appear to vary their tints according to the nature of the ground over which they pass : when in deep water, their general shade was brownish purple, but when placed on the land, or in shallow water, this dark tint changed into one of a yellowish green. The colour, examined more carefully, was a French grey, with numerous minute spots of bright yellow : the former of these varied HABITS OF A CUTTLE-FISH. 7 in intensity ; the latter entirely disappeared and appeared again by turns. These changes were effected in such a manner, that clouds, varying in tint between a hyacinth red and a chestnut-brown,* were continually passing over the body. Any part, being subjected to a slight shock of galvanism, became almost JLdack : a similar eftect, but in a less degree, was produced by scratching the skin with a needle. These clouds, or blushes as they may be called, are said to be produced by the alternate expansion and contraction of minute vesicles containing variously coloured fluids.f This cuttle-fish displayed its chameleon-like power both during the act of swimming and whilst remaining stationary at the bottom. I was much amused by the various arts to escape detection used by one individual, which seemed fully aware that I was watching it. Remaining for a time motionless, it would then stealthily advance an inch or two, like a cat after a mouse ; sometimes changing its colour : it thus proceeded, till having gained a deeper part, it darted away, leaving a dusky train "of ink to hide the hole into which it had crawled. While looking for marine animals, with my head about two feet above the rocky shore, I was more than once saluted by a jet of water, accompanied by a slight grating noise. At first I could not think what it was, but afterwards I found out that it was this cuttle-fish, which, though concealed in a hole, thus often led me to its discovery. That it possesses the power of ejecting water there is no doubt, and it appeared to me that it could certainly take good aim by directing the tube or siphon on the under side of its body. From the difficulty which these animals have in carrying their heads, they cannot crawl with ease when placed on the ground. I observed that one which I kept in the cabin was slightly phospho- rescent in the dark. ST. PAUL'S ROCKS. — In crossing the Atlantic we hove-to, during the morning of February 16th, close to the island of St. Paul's. This cluster of rocks is situated in 0° 58' north latitude, and 29° 15' west longitude. It is 540 miles distant from the coast of America, and 350 from the island of Fernando Norouha. The highest point is only fifty feet above the level of the sea, and the entire circum- ference is under three-quarters of a mile. This small point rises * So named according to Patrick Symes's nomenclature, t See Encyclop. of Anat. and Physiol., article Cephalopoda. 8 ST. PAUL'S EOCKS. [CHAP, j, abruptly out of the deptlis of the ocean. Its mineralogical consti- tution is not simple ; in some parts the rock is of a cherty, in others of a felspathic nature, including thin veins of serpentine. It is a remarkable fact, that all the many small islands, lying far from any continent, in the Pacific, Indian, and Atlantic Oceans, with the exception of the Seychelles and this little point of rock, are, I be- lieve, composed either of coral or of erupted matter. The volcanic nature of these oceanic islands is evidently an extension of that law, and the effect of those same causes, whether chemical or mechanical, from which it results that a vast majority of the volcanoes now in action stand either near sea-coasts or as islands in the midst of the sea. The rocks of St. Paul appear from a distance of a brilliantly white colour. This is partly owing to the dung of a vast multitude of sea-fowl, and partly to a coating of a hard glossy substance with a pearly lustre, which is intimately iinited to the surface of the rocks. This, when examined with a lens, is found to consist of numerous exceedingly thin layers, its total thickness being about the tenth of an inch. It contains much animal matter, and its origin, no doubt, is due to the action of the rain or spray on the birds' dung. Below some small masses of guano at Ascension, and on the Abrolhos Islets, I found certain stalactitic branching bodies, formed apparently in the same manner as the thin white coating on these rocks. The branching bodies so closely resembled in general appearance certain nulliporso (a family of hard calcareous sea- plants), that in lately looking hastily over my collection I did not 1832.] SINGULAR INCRUSTATIONS. 9 perceive the difference. The globular extremities of the branches are of a pearly texture, like the enamel of teeth, but so hard as just to scratch plate-glass. I may here mention, that on a part of the coast of Ascension, where there is a vast accumulation of shelly sand, an incrustation is deposited on the tidal rocks by the water of the sea, resembling, as represented in the woodcut, certain crypto- gamic plants (Marchantiaj) often seen on damp walls. The surface of the fronds is beautifully glossy ; and those parts formed where fully exposed to the light, are of a jet black colour, but those shaded under ledges are only grey. I have shown specimens of this in- crustation to several geologists, and they all thought that they were of volcanic or igneous origin ! In its hardness and translucency— in its polish, equal to that of the finest oliva-shell— in the bad smell given out, and loss of colour under the blowpipe— it shows a close similarity with living sea-shells. Moreover in sea-shells, it is known that the parts habitually covered and shaded by the mantle of the animal, are of a paler colour than those fully exposed to the light, just as is the case with this incrustation. When we remember that lime, either as a phosphate or carbonate, enters into the composition of the hard parts, such as bones and shells, of all living animals, it is an interesting physiological fact * to find substances harder than the enamel of teeth, and coloured surfaces as well polished as those of a fresh shell, reformed through inorganic means from dead organic matter — mocking, also, in shape some of the lower vegetable productions. We found on St. Paul's only two kinds of birds— the booby and the noddy. The former is a species of gannet, and the latter a tern. Both are of a tame and stupid disposition, and are so unaccustomed to visitors, that I could have killed any number of them with my geological hammer. The booby lays her eggs on the bare rock ; but the tern makes a very simple nest with seaweed. By the side of many of these nests a small flying-fish was placed ; which, I sup- pose, had been brought by the male bird for its partner. It was * Mr. Homer and Sir David Brewster have described (Philosophical Transactions, 1836, p. G5) a singular " artificial substance resembling shell." It is deposited in fine, transparent, highly polished, brown-coloured laminae, possessing peculiar optical properties, on the inside of a vessel, in which cloth, first prepared -with glue and then with lime, is made to revolve rapidly in water. It is much softer, more transparent, and contains more animal matter, than the natural incrustation at Ascension ; but we here again see the strong tendency which carbonate of lime and animal matter evince to form a solid substance allied to shell. 10 FERNANDO NORONHA. [CHAP. i. amusing to watch how quickly a large aud active crab (Graspus), which inhabits the crevices of the rock, stole the fish from the side of the nest, as soon as we had disturbed the parent birds. Sir \V. Syrnonds, one of the few persons who have landed here, informs roc that he saw the crabs dragging even the young birds out of their nests, and devouring them. Not a single' plant, not even a lichen, grows on this islet ; yet it is inhabited by several insects and spiders. The following list completes, I believe, the terrestrial fauna : a fly (Olfersia) living on the booby, and a tick which must have come here as a parasite on the birds ; a small brown moth, belonging to a genus that feeds on feathers ; a beetle (Quedius) and a woodlouse from beneath the dung ; and lastly, numerous spiders, which I sup- pose prey on these small attendants and scavengers of the water- fowl. The often repeated description of the stately palm and other noble tropical plants, then birds, and lastly man, taking possession of the coral islets as soon as formed, in the Pacific, is probably not correct ; I fear it destroys the poetry of this story, that feather and dirt-feeding and parasitic insects and spiders should be the first inhabitants of newly formed oceanic land. The smallest rock in the tropical seas, by giving a foundation for the growth of innumerable kinds of seaweed and compound animals, supports likewise a large number of fish. The sharks and the seamen in the boats maintained a constant struggle which should secure the greater share of the prey caught by the fishing-lines. I have heard that a rock near the Bermudas, lying many miles out at sea, and at a considerable depth,was first discovered by the circum- stance of fish having been observed in the neighbourhood. FKRXANDO NORONHA, Feb. 20th. — As far as I was enabled to observe, during the few hours we stayed at this place, the constitu- tion of the island is volcanic, but probably not of a recent date. The most remarkable feature is a conical hill, about one thousand feet high, the upper part of which is exceedingly steep, and on one side overhangs its base. The rock is phonolite, and is divided into irregular columns. On viewing one of these isolated masses, at first one is inclined to believe that it has been suddenly -pushed up in a semi-fluid state. At St. Helena, however, I ascertained that some pinnacles, of a nearly similar figure and constitution, had been formed by the injection of melted rock into yielding strata, which thus had formed the moulds for these gigantic obelisks. 1832.] BAHIA— BRAZIL. 11 The whole island is covered with wood ; but from the dryuess of the climate there is no appearance of luxuriance. Half-way up the mountain, some great masses of the columnar rock, shaded by laurel-like trees, and ornamented by others covered with fine pink flowers but without a single leaf, gave a pleasing effect to the nearer parts of the scenery. BAHIA, OR SAN SALVADOR. BRAZIL, Feb. 29 continent, whore the western gales, charged witli moisture from the Pacific, prevail, every island on the broken west coast, from lat. 38° to the extreme point of Tierra del Fuego, is densely covered by -impenetrable forests. On tho eastern side of the Cordillera, over the same extent of latitude, where a blue sky and a fine climate prove that the atmosphere has been deprived of its moisture by passing over the mountains, the arid plains of Patagonia support a most scanty vegetation. In the more northern parts of the con- tinent, within the limits of the constant south-eastern trade-wind, the eastern side is ornamented by magnificent forests ; whilst the western coast, from lat. 4° S. to lat. 32D S., may be described as a desert : on this western coast, northward of lat. 4° S., where tho trade-wind loses its regularity, and heavy torrents of rain fall periodically, tho shores of the Pacific, so utterly desert in Peru, assume near Cape Blanco the character of luxuriance so celebrated at Guyaquil and Panama. Hence in the southern and northern parts of the continent, the forest and desert lands occupy reversed positions with respect to the Cordillera, and these positions are apparently determined by the direction of the prevalent winds. In the middle of the continent there is a broad intermediate band, including central Chile and the provinces of La Plata, where the rain-bringing winds have not to pass over lofty mountains, and where the land is neither a desert nor covered by forests. But even the rule, if confined to South America, of trees flourishing only in a climate rendered humid by rain-bearing winds, has a strongly marked exception in the case of the Falkland Islands. These islands, situated in the same latitude with Tierra del Fuego and only between two and three hundred miles distant -from it, having a nearly similar climate, with a geological formation almost identical, with favourable situations and the same kind of peaty soil, yet can boast of few plants deserving even the title of bushes; whilst in Tierra del Fuego it is impossible to find an acre of land not covered by the densest forest. In this case, both the direction of the heavy gales of wind and of the currents of the sea are favour- able to the transport of seeds from Tierra del Fuego, as is shown by the canoes and trunks of trees drifted from that country, and frequently thrown on the shores of the Western Falkland. Hence perhaps it is, that there are many plants in common to the two countries; but with respect to the trees of Tierra del Fuego, even attempts made to transplant them have failed. 46 MALDONADO. [CHAP. in. During our stay at Maldonaclo I collected several quadrupeds, eighty kinds of birds, and many reptiles, including nine species of snakes. Of the indigenous mammalia, the only one now left of any size, which is common, is the Cervus campestris. This deer is exceedingly abundant, often in small herds, throughout the countries bordering the Plata and in Northern Patagonia. If a person crawling close along the ground, slowly advances towards a herd, the deer frequently, out of curiosity, approach to reconnoitre him. I have by this means killed, from one spot, three out of the same herd. Although so tame and inquisitive, yet when approached on horseback, they are exceedingly wary. In this country nobody goes on foot, and the deer knows man as its enemy only when he is mounted and armed with the bolas. At Bahia Blanca, a recent establishment in Northern Patagonia, I was surprised to find how little the deer cared for the noise of a gun : one day I fired ten times from within eighty yards at one animal ; and it was much more startled at the ball cutting up the ground than at the report of the rifle. My powder being exhausted, I was obliged to get up (to my shame as a sportsman be it spoken, though well able to kill birds on the wing) and halloo till the deer ran away. The most curious fact with respect to this animal, is the over- poweringly strong and offensive odour which proceeds from the buck. It is quite indescribable : several times whilst skinning the specimen which is now mounted at the Zoological Museum, I was almost overcome by nausea. I tied up the skin in a silk pocket- handkerchief, and so carried it home: this handkerchief, after being well washed, I continually used, and it was of course as repeatedly washed ; yet every time, for a space of one year and seven montbs, when first unfolded, I distinctly perceived the odour. This appears an astonishing instance of the permanence of some matter, which nevertheless in its nature nmst be most subtile and volatile. Frequently, when passing at the distance of half a mile to leeward of a herd, I have perceived the whole air tainted with the effluvium. I believe the smell from the buck is most powerful at the period when its horns are perfect, or free from the hairy skin. When in this state the meat is, of course, quite uneatable ; but the Gauchos assert, that if buried for some time in fresh earth, the taint is removed. I have somewhere read that the islanders in the north of Scotland treat the rank carcasses of the fish-eating birds in the same manner. 1832-3.] THE CAPYBARA, OR WATER-HOG. 47 The order Rodentia is here very numerous in species : of mice alone I obtained no less than eight kinds.* The largest gnawing animal in the world, the Hydrochserus capybara (the water-hog), is here also common. One which I shot at Monte Video weighed ninety-eight pounds : its length, from the end of the snout to the stump-like tail, was three feet two inches ; and its girth three feet eight. These great Rodents occasionally frequent the islands in the mouth of the Plata, where the water is quite salt, but are far more abundant on the borders of fresh-water lakes and rivers. Near Maldonado three or four generally live together. In the day- time they either lie among the aquatic plants, or openly feed on the turf plain.f When viewed at a distance, from their manner of walking and colour they resemble pigs : but when seated on their haunches, and attentively watching any object with one eye, they reassume the appearance of their congeners, cavies and rabbits. Both the front and side view of their head has quite a ludicrous aspect, from the great depth of their jaw. These animals, at Maldonado, were very tame ; by cautiously walking, I approached within three yards of four old ones. This tameness may probably bo accounted for, by the Jaguar having been banished for some years, and by the Gaucho not thinking it worth his while to hunt them. As I approached nearer and nearer they frequently made their peculiar noise, which is a low abrupt grunt, not having much actual sound, but rather arising from the sudden expulsion of air : the only noise I know at all like it, is the first hoarse bark of a large dog. Having watched the four from almost within arm's length (and they me) for several minutes, they rushed into the water at full gallop with the greatest impetuosity, and emitted at the same time their bark. After diving a short distance they came again to the surface, but only just showed the upper part of their * In South America I collected altogether twenty-seven species of mice, and thirteen more are known from the works of Azara and other authors. Those collected by myself have been named and described by Mr. Waterhouse at the meetings of the Zoological Society. I must be allowed to take this opportunity of returning my cordial thanks to Mr. Waterhouse, and to the other gentlemen attached to that Society, for their kind and most liberal assistance on all occasions. t In the stomach and duodenum of a capybara which I opened, I found a very large quantity of a thin yellowish fluid, in which scarcely a fibre could be distinguished. Mr. Owen informs me that a part of the rcsophagus is so constructed that nothing much larger than a crowquill can be passed down. Certainly the broad teeth and strong jaws of this animal are well fitted to grind into pulp the aquatic plants ou which it feeds. 48 MALDONADO. [fii.\r. HI. heads. When the female is swimming in the water, and has young ones, they are said to sit on her back. These animals are easily killed in numbers ; but their skins are of trifling value, and the meat is very indifferent. On the islands in the Eio Parana they are exceedingly abundant, and afford the ordinary prey to the Jaguar. The Tucutuco (Ctenomys Brasiliensis) is a curious small animal, which may be briefly described as a Gnawer, with the habits of a mole. It is extremely numerous in some parts of the country, but is difficult to be procured, and never, I believe, comes out of the ground. It throws up at the mouth of its burrows hillocks of earth like those of the mole, but smaller. Considerable tracts of country are so completely undermined by these animals, that horses in passing over, sink above their fetlocks. The tucutucos appear, to a certain degree, to be gregarious : the man who procured the specimens for me had caught six together, and he said this was a common occurrence. They are nocturnal in their habits ; and their principal food is the roots of plants, which are the object of their extensive and superficial burrows. This animal is universally known by a very peculiar noise which it makes when beneath the ground. A person, the first time he hears it, is nmch surprised ; for it is not easy to tell whence it conies, nor is it possible to guess what kind of creature utters it. The noise consists in a short, but not rough, nasal grunt, which is monotonously repeated about four times in quick succession : * the name Tucutuco is given in imita- tion of the sound. Where this animal is abundant, it may be heard at all times of the day, and sometimes directly beneath one's feet. When kept in a room, the tucutucos move both slowly and clumsily, which appears owing to the outward action of their hind legs; and they are quite incapable, from the socket of the thigh-bone not having a certain ligament, of jumping even the smallest vertical height. They are very stupid in making any attempt to escape ; when angry or frightened they uttered the tucu-tuco. Of those I kept alive several, even the first day, became quite tame, not attempting to bite or to run away ; others were a little wilder. * At the E. Negro, in Northern Patagonia, there is an animal of the same habits, and probably a closely allied species, but which I never saw. Its noise is different from that of the Maklonado kind ; it is repeated only twice instead of three or four times, and is more distinct and sonorous : when heard from a distance it so closely resembles the sound made in cutting down a small tree with an axe, that I have sometime? remained in doubt concerning it. 1832*3.] THE TUCUTUCO. 49 The man who caught them asserted that very many are inva- riably found blind. A specimen which I preserved in spirits was in this state ; Mr. Eeid considers it to be the effect of inflammation in the nictitating membrane. When the animal was alive I placed my finger within half an inch of its head, and not the slightest notice was taken : it made its way, however, about the room nearly as well as the others. Considering the strictly subterranean habits of the tucutuco, the blindness, though so common, cannot be a very serious evil ; yet it appears strange that any animal should possess an organ frequently subject to be injured. Lamarck would have been delighted with this fact, had he known it, when speculating * (probably with more truth than usual with him) on the gradually acquired blindness of the Aspalax, a Gnawer living under ground, and of the Proteus, a reptile living in dark caverns filled with water; in both of which animals the eye is in an almost rudi- mentary state, and is covered by a tendinous membrane and skin. In the common mole the eye is extraordinarily small but perfect, though many anatomists doubt whether it is connected with the true optic nerve ; its vision must certainly be imperfect, though probably useful to the animal when it leaves its burrow. In the tucutuco, which I believe never comes to the surface of the ground, the eye is rather larger, but often rendered blind and useless, though without apparently causing any inconvenience to the animal ; no doubt Lamarck would have said that the tucutuco is now passing into the state of the Aspalax and Proteus. Birds of many kinds are extremely abundant on the undulating grassy plains around Maldonado. There are several species of a family allied in structure and manners to our Starling: one of these (Molothrus niger) is remarkable from its habits. Several may often be seen standing together on the back of a cow or horse ; and while perched on a hedge, pluming themselves in the sun, they sometimes attempt to sing, or rather to hiss; the noise being very peculiar, resembling that of bubbles of air passing rapidly from a small orifice under water, so as to produce an acute sound. Accord- ing to Azara, this bird, like the cuckoo, deposits its eggs in other birds' nests. I was several times told by the country people that there certainly is some bird having this habit ; and my assistant in collecting, who is a very accurate person, found a nest of the sparrow of this country (Zouotrichia matutina), with one egg in it * Philosoph. Zoolog., torn. i. p. 242. E 50 MALDONADO. tciiAi'. ni. larger than the others, and of a different colour and shape. In North America there is another species of Molothrus (M. pecoris), which has a similar cuckoo-like habit, and which is most closely allied in every respect to the species from the Plata, even in such trifling peculiarities as standing on the backs of cattle ; it differs only in being a little smaller, and in its plumage and eggs being of a slightly different shade of colour. This close agreement in structure and habits, in representative species coming from opposite quarters of a great continent, always strikes one as interesting, though of common occurrence. Mr. Swainson has well remarked,* that with the exception of the Molothrus pecoris, to which must be added the M. niger, the citckoos are the only birds which can be called truly parasitical : namely, such as " fasten themselves, as it were, on another living animal, whose animal heat brings their young into life, whose food they live upon, and whose death would cause theirs during the period of infancy." It is remarkable that some of the species, but not all, both of the Cuckoo and Molothrus should agree in this one strange habit of their parasitical propagation, whilst opposed to each other in almost every other habit : the molothrus, like our starling, is eminently sociable, and lives on the open plains without art or disguise : the cuckoo, as every one knows, is a singularly shy bird; it frequents the most retired thickets, and feeds on fruit and cater- pillars. In structure also these two genera are widely removed from each other. Many theories, even phrenological theories, have been advanced to explain the origin of the cuckoo laying its eggs in other birds' nests. M. Prevost alone, I think, has thrown light by his observations f on this puzzle : he finds that the female cuckoo, which, according to most observers, lays at least from four to six eggs, must pair with the male each time after laying only one or two eggs. Now, if the cuckoo was obliged to sit on her own eggs, she would either have to sit on all together, and therefore leave those first laid so long, that they probably would become addled ; or she would have to hatch separately each egg or two eggs, as soon as laid : but as the cuckoo stays a shorter time in this country than any other migratory bird, she certainly would not have time enough for the successive hatchings. Hence we can perceive in the fact of the cuckoo pairing several times, and laying * Magazine of Zoology ami Botany, vol. i. p. 217. t Kead before the Academy of Sciences in Puris. L'luslitut, 1834, p. 418. 1832-3.] THE TYRANT-FLYCATCHER. 51 her eggs at intervals, the cause of her depositing her eggs ill other birds' nests, and leaving them to the care of foster-parents. I am strongly inclined to believe that this view is correct, from having been independently led (as we shall hereafter see) to an analogous conclusion with regard to the South American ostrich, the females of which are parasitical, if I may so express it, on each other ; each female laying several eggs in the nests of several other females, and the male ostrich undertaking all the cares of incubation, like the strange foster-parents with the cuckoo. I will mention only two other birds, which are very common, and render themselves prominent from their habits. The Sauro- phagus sulphuratus is typical of the great American tribe of tyrant-flycatchers. In its structure it closely approaches the true shrikes, but in its habits may be compared to many birds. I have frequently observed it, hunting a field, hovering over one spot like a hawk, and then proceeding on to another. When seen thus suspended in the air, it might very readily at a short distance be mistaken for one of the Eapacious order ; its stoop, however, is very inferior in force and rapidity to that of a hawk. At other times the Saurophagus haunts the neighbourhood of water, and there, like a kingfisher, remaining stationary, it catches any small fish which may come near the margin. These birds are not un- frequently kept either in cages or in courtyards, with their wiugs cut. They soon become tame, and are very amusing from their cunning odd manners, which were described to me as being similar to those of the common magpie. Their flight is uudulatory, for the weight of the head and bill appears too great for the body. In the evening the Saurophagus takes its stand on a bush, often by the roadside, and continually repeats without change a shrill and rather agreeable cry, which somewhat resembles articulate words : the Spaniards say it is like the words " Bien te veo " (I see you well), and accordingly have given it this name. A mocking-bird (Mimus orpheus), called by the inhabitants Calandria, is remarkable, from possessing a song far superior to that of any other bird in the country : indeed, it is nearly the only bird in South America which I have observed to take its stand for the purpose of singing. The song may be compared to that of the Sedge warbler, but is more powerful ; some harsh notes and some very high ones, being mingled with a pleasant warbliug. It is heard only during the spring. At other times its cry is harsh and 52 MALDONADO. [CHAP. in. far from harmonious. Near Maldouado these birds were tame and bold ; they constantly attended the country houses in numbers, to pick the meat which was hung up on the posts or walls : if any other small bird joined the feast, the Calandria soon chased it away. On the wide uninhabited plains of Patagonia another closely allied species, 0. Patagouica of d'Orbigny, which frequents the valleys clothed with spiny bushes, is a wilder bird, and has a slightly different tone of voice. It appears to me a curious circumstance, as showing the fine shades of difference in habits, that judging from this latter respect alone, when I first saw this second species, I thought it was different from the Maldonado kind. Having afterwards procured a specimen, and comparing the two without particular care, they appeared so very similar, that I changed my opinion ; but now Mr. Gould says that they are certainly distinct ; a conclusion in conformity with the trifling difference of habit, of which, however, he was not aware. The number, tameness, and disgusting habits of the carrion- feeding hawks of South America make them pre-eminently striking to any one accustomed only to the birds of Northern Europe. In this list may be included four species of the Caracara or Polyborus, the Turkey buzzard, the Gallinazo, and the Condor. The Caracaras are, from their structure, placed among the eagles : we shall soon see how ill they become so high a rank. In their habits they well supply the place of our carrion-crows, magpies, and ravens ; a tribe of birds widely distributed over the rest of the world, but entirely absent in South America. To begin with the Polyborus Brasiliensis : this is a common bird, and has a wide geographical range ; it is most numerous on the grassy savannahs of La Plata (where it goes by the name of Carrancha), and is far from unfrequent throughout the sterile plains of Patagonia. In the desert between the rivers Negro and Colorado, numbers constantly attend the line of road to devour the carcasses of the exhausted animals which chance to perish from fatigue and thirst. Although thus common in these dry and open countries, and likewise on the arid shores of the Pacific, it is nevertheless found inhabiting the damp impervious forests of West Patagonia and Tierra del Fucgo. The Carrauchas, together with the Chimango, constantly attend in numbers the estaucias and slaughtering-houses. If an animal dies on the plain the Gallinazo commences the feast, and then the two species of Polyborus pick the bones clean. These birds, although thus com • 1832-3.] OAJIRION HAWKS. 53 monly feeding together, are far from being friends. When the Carrancha is quietly seated on the branch of a tree or on the ground, the Chimango often continues for a long time flying backwards and forwards, up and down, in a semicircle, trying each time at the bot- tom of the curve to strike its larger relative. The Carrancha takes little notice, except by bobbing its head. Although the Carranchas frequently assemble in numbers, they are not gregarious ; for in desert places they may be seen solitary, or more commonly by pairs. The Carranchas are said to be very crafty, and to steal great numbers of eggs. They attempt, also, together with the Chimango, to pick off the scabs from the sore backs of horses and mules. The poor animal, on the one hand, with its ears down and its back arched ; and, on the other, the hovering bird, eyeing at the distance of a yard the disgusting morsel, form a picture, which has been described by Captain Head with his own peculiar spirit and ac- curacy. These false eagles most rarely kill any living bird or animal ; and their vulture-like, necrophagous habits are very evi- dent to any one who has fallen asleep on the desolate plains of Patagonia, for when he wakes, he will see, on each surrounding hillock, one of these birds patiently watching him with an evil eye : it is a feature in the landscape of these countries, which will be recognise! by every one who has wandered over them. If a party of men go out hunting with dogs and horses, they will be accom- panied, during the day, by several of these attendants. After feeding, the uncovered craw protrudes ; at such times, and indeed generally, the Carrancha is an inactive, tame, and cowardly bird. Its flight is heavy and slow, like that of an English rook. It seldom soars ; but I have twice seen one at a great height gliding through the air with much ease. It runs (in contradistinction to hopping), but not quite so quickly as some of its congeners. At times the Carrancha is noisy, but is not generally so : its cry is loud, very harsh and peculiar, and may be likened to the sound of the Spanish guttural g, followed by a rough double r r ; when uttering this cry it elevates its head higher and higher, till at last, with its beak wide open, the crown almost touches the lower part of the back. This fact, which has been doubted, is quite true; I have seen them several times with their heads backwards in a completely inverted position. To these observations I may add, on the high authority of Azara, that the Carrancha feeds on worms, shells, slugs, grass- hoppers, and frogs ; that it destroys young lambs by tearing the um- 5-1 MALDOXADO. [CHAP. in. bilicnl cord ; and that it pursues the Gallinazo, till that bird is com- pelled to vomit up the carrion it may have recently gorged. Lastly, Azara states that several Carranchas, five or six together, will unite in chase of large birds, even such as herons. All these facts show that it is a bird of very versatile habits and considerable ingenuity. The Polyborus Chimango is considerably smaller than the last species. It is truly omnivorous, and will eat even bread ; and I was assured that it materially injures the potato-crops in Chiloe, by stocking up the roots when first planted. Of all the carrion-feeders it is generally the last which leaves the skeleton of a dead animal and may often be seen within the ribs of a cow or horse, like a bird in a cage. Another species is the Polyborus Nova? Zelandirc, which is exceedingly common in the Falkland Islands. These birds in many respects resemble in their habits the Carranchas. They live on the flesh of dead animals and on marine productions ; and on the Eamirez rocks their whole sustenance must depend on the sea. They are extraordinarily tame and fearless, and haunt the neighbourhood of houses for offal. If a hunting party kills an animal, a number soon collect and patiently await, standing on the ground on all sides. After eating, their uncovered craws are largely protruded, giving them a disgusting appearance. They readily attack wounded birds : a cormorant in this state having taken to the shore, was immediately seized on by several, and its death hastened by their blows. The Beagle was at the Falklands only during the summer, but the officers of the Adventure, who were there in the winter, mention many extraordinary instances of the boldness and rapacity of these birds. They actually pounced on a dog that was lying fast asleep close by one of the party ; and the sportsmen Imd difficulty in preventing the wounded geese from being seized before their eyes. It is said that several together (in this respect resembling the Carranchas) wait at the mouth of a rabbit-hole, and together seize on the animal when it comes out. They were constantly flying on board the vessel when in the har- bour ; and it was necessary to keep a good look out to prevent the leather being torn from the rigging, and the meat or game from the stern. These birds are very mischievous and inquisitive; they will pick up almost anything from the ground ; a large black glazed hat was carried nearly a mile, as was a pair of the heavy balls used in catching cattle. Mr. Usborne experienced during the survey a more severe loss, in their stealing a small Eater's compass in a red CARRION HAWKS. 55 morocco leather case, which was never recovered. These birds arc, moreover, quarrelsome and very passionate ; tearing up the grass with their bills from rage. They are not truly gregarious ; they do not soar, and their flight is heavy and clumsy ; on the ground they run extremely fast, very much like pheasants. They are noisy, uttering several harsh cries, one of which is like that of the Eng- lish rook ; hence the sealers always call them rooks. It is a curious circumstance that, when crying out, they throw their heads up- wards and backwards, after the same manner as the Carrancha. They build in the rocky cliffs of the sea-coast, but only on the small adjoining islets, and not on the two main islands : this is a singular precaution in so tame and fearless a bird. The sealers say that tho flesh of these birds, when cooked, is quite white, and very good eating ; but bold must the man be who attempts such a meal. We have now only to mention the turkey-buzzard (Vultur aura), and the Gallinazo. The former is found wherever the country is moderately damp, from Cape Horn to North America. Differently from thePolyborus Brasiliensis and Chimango, it has found its way to the Falkland Islands. The turkey-buzzard is a solitary bird, or at most goes in pairs. It may at once be recognised from a long distance, by its lofty, soaring, and most elegant flight. It is well known to be a true carrion-feeder. On the west coast of Patagonia, among the thickly- wooded islets and broken land, it lives exclusively on what the sea throws up, and on tho carcasses of dead seals. Wherever these animals are congregated on the rocks, there tho vultures may be seen. The Gallinazo (Cathartes atratus) has a different range from the last species, as it never occurs southward of lat. 41°. Azara states that there exists a tradition that these birds, at the time of the conquest, were not found near Monto Video, but that they subsequently followed the inhabitants from more northern districts. At the present day they are numerous in the valley of the Colorado, which is three hundred miles due south of Monte Video. It seems probable that this additional migration has happened since the time of Azara. The Gallinazo generally prefers a humid climate, or rather the neighbourhood of fresh water; hence it is extremely abundant in Brazil and La Plata, while it is never found on the desert and arid plains of Northern Patagonia, excepting near some stream. These birds frequent the whole Pampas to the foot of the Cordillera, but I never saw or heard of one in Chile: in Peru they are preserved as scavengers. 56 MALDONADO. [CHAP. in. These vultures certainly may be called gregarious, for they seem to have pleasure in society, and are not solely brought together by the attraction of a common prey. On a fine day a flock may often be observed at a great height, each bird wheeling round and round without closing its wings, in the most graceful evolutions. This is clearly performed for the mere pleasure of the exercise, or perhaps is connected with their matrimonial alliances. I have now mentioned all the carrion-feeders, excepting the condor, an account of which will be more appropriately intro- duced when we visit a country more congenial to its habits than the plains of La Plata. In a broad band of sand-hillocks which separate the Laguua del Potrero from the shores of the Plata, at the distance of a few miles from Maldonado, I found a group of those vitrified, siliceous tubes, which are formed by lightning entering loose sand. These tub?s resemble in every particular those from Drigg in Cumber- land, described in the Geological Transactions.* The sand- hillocks of Maldonado, not being protected by vegetation, arc constantly changing their position. From this cause the tubes projected above the surface, and numerous fragments lying near, showed that they had formerly been buried to a greater depth. Four sets entered the sand perpendicularly : by working with my hands I traced one of them two feet deep ; and some fragments which evidently had belonged to the same tube, when added to the other part, measured five feet three inches. The diameter of the whole tube was nearly equal, and therefore we must suppose that originally it extended to a much greater depth. These dimensions are however small, compared to those of the tubes from Drigg, one of which was traced to a depth of not less than thirty feet. The internal surface is completely vitrified, glossy, and smooth. A small fragment examined under the microscope appeared, from the number of minute entangled air or perhaps steam bubbles, like an assay fused before the blowpipe. The sand is entirely, or in greater part, siliceous; but some points are of a black colour, and from their glossy surface possess a metallic lustre. The thickness * Geolog. Transact., vol. ii. p. 528. In the Philosoph. Transact. (1790, p. 294) Dr. Priestley has described some imperfect siliceous tubes and a melted pebble of quartz, found in digging into the ground, under a tree, where a man had been killed by lightning. 1832-3.] TUBES FORMED BY LIGHTNIXG. 57 of the wall of the tube varies from a thirtieth to a twentieth of an inch, and occasionally even equals a tenth. On the outside the grains of sand are rounded, and have a slightly glazed appearance : I could not distinguish any signs of crystallization. In a similar manner to that described in the Geological Transactions, the tubes are generally compressed, and have deep longitudinal furrows, so as closely to resemble a shrivelled vegetable stalk, or the bark of the elm or cork tree. Their circumference is about two inches, but in some fragments, which are cylindrical and without any furrows, it is as much as four inches. The compression from the surrounding loose sand, acting while the tube was still softened from the effects of the intense heat, has evidently caused the creases or furrows. Judging from the uncompressed fragments, the measure or bore of the lightning (if such a term may be used) must have been about one inch and a quarter. At Paris, M. Hachette and M. Beudant * succeeded in making tubes, in most respects similar to these fulgurites, by passing very strong shocks of galvinism through finely-powdered glass : when salt was added, so as to increase its fusibility, the tubes were larger in every dimension. They failed both with powdered felspar and quartz. One tube, formed with pounded glass, was very nearly an inch long, namely, '982, and had an internal diameter of -019 of an inch. When we hear that the strongest battery in Paris was used, and that its power on a substance of such easy fusibility as glass was to form tubes so diminutive, we must feel greatly astonished at the force of a shock of lightning, which, striking the sand in several places, has formed cylinders, in one instance of at least thirty feet long, and having an internal bore, where not compressed, of full an inch and a half; and this in a material so extraordi- narily refractory as quartz ! The tubes, as I have already remarked, enter the sand nearly in a vertical direction. One, however, which was less regular than the others, deviated from a right line, at the most consider- able bend, to the amount of thirty-three degrees. From this same tube, two small branches, about a foot apart, were sent off; one pointed downwards, and the other upwards. This latter case is remarkable, as the electric fluid must have turned back at the acute angle of 26°, to the line of its main course. Besides the four tubes which I found vertical, and traced beneath the surface, thero * Annals de Chinrie et de Physique, torn, xxxvii. p. 319. 58 MALDONADO. [CHAP. in. were several other groups of fragments, the original sites of which •without doubt were near. All occurred in a level area of shifting sand, sixty yards by twenty, situated among some high sand-hil- locks, and at the distance of about half a mile from a chain of hills four or five hundred feet in height. The most remarkable circum- stance, as it appears to me, in this case as well as in that of Drigg, and in one described by M. Eibbentrop in Germany, is the number of tubes found within such limited spaces. At Drigg, within an area of fifteen yards, three were observed, and the same number occurred in Germany. In the case which I have described, certainly more than four existed within the space of the sixty by twenty yards. As it does not appear probable that the tubes are produced by successive distinct shocks, we must believe that the lightning, shortly before entering the ground, divides itself into separate branches. The neighbourhood of the Rio Plata seems peculiarly subject to electric phenomena. In the year 1793,* one of the most destruc- tive thunderstorms perhaps on record happened at Buenos Ayres : thirty-seven places within the city were struck by lightning, and nineteen people killed. From facts stated in several books of travels, I am inclined to suspect that thunderstorms are very common near the mouths of great rivers. Is it not possible that the mixture of large bodies of fresh and salt water may disturb the electrical equilibrium ? Even during our occasional visits to this part of South America, we heard of a ship, two churches, and a house having been struck. Both the church and the house I saw shortly afterwards : the house belonged to Mr. Hood, the consul-general at Monte Video. Some of the effects were curious : the paper, for nearly a foot on each side of the line where the bell-wires had run, was blackened. The metal had been fused, and although the room was about fifteen feet high, the globules, dropping on the chairs and furniture, had drilled in them a chain of minute holes. A part of the wall was shattered as if by gunpowder, and the fragments had been blown off with force sufficient to dent the wall on the opposite side of the room. The frame of a looking-glass was blackened, and the gilding must have been volatilized, for a smelling-bottle, which stood on the chimney-piece, was coated with bright metallic particles, which adhered as firmly as if they had been enamelled. * Azara's Voyage, vol. i. p. 3G. 18;',;!.] ARRIVE AT RIO XF.DRO. 59 CHAPTER IV.

RIO NEGEO TO BAHIA BLANCA. July 21th, 1833. — The Beagle sailed from Maldonado, and on August the 3rd she arrived off the mouth of the Rio Negro. This is the principal river on the whole line of coast between the Strait of Magellan and the Plata. It enters the sea about three hundred miles south of the estuary of the Plata. About fifty years ago, under the old Spanish government, a small colony was established here ; and it is still the most southern position (lat. 41°) on this eastern coast of America inhabited by civilized man. The country near the mouth of the river is wretched in the extreme: on the south side a long line of perpendicular cliffs commences, which exposes a section of the geological nature of the country. The strata are of sandstone, and one layer was remark- able from being composed of a firmly-cemented conglomerate of pumice pebbles, which must have travelled more than four hundred miles, from the Andes. The surface is everywhere covered up by a thick bed of gravel, which extends far and wide over the open plain. Water is extremely scarce, and, where found, is almost invariably brackish. The vegetation is scanty; and although there are bushes of many kinds, all are armed with formidable thorns, which seem to warn the stranger not to enter on these inhospitable regions. The settlement is situated eighteen miles up the river. The road follows the foot of the sloping cliff, which forms the northern boundary of the great valley, in which the Rio Negro flows. On 60 TtlO NEGRO. [CHAP. iv. the way we passed the ruins of some fine " estancias," which a few years since had been destroyed by the Indians. They withstood several attacks. A man present at one gave me a very lively description of what took place. The inhabitants had sufficient notice to drive all the cattle and horses into the " corral " * which surrounded the house, and likewise to mount some small cannon. The Indians were Araucanians from the south of Chile ; several hundreds in number, and highly disciplined. They first appeared in two bodies on a neighbouring hill; having there dismounted, and taken off their fur mantles, they advanced naked to the charge. The only weapon of an Indian is a very long bamboo or chuzo, ornamented with ostrich feathers, and pointed by a sharp spear- head. My informer seemed to remember with the greatest horror the quivering of these chuzos as they approached near. When close, the cacique Pincheira hailed the besieged to give up their arms, or he would cut all their throats. As this would probably have been the result of their entrance under any circumstances, the answer was given by a volley of musketry. The Indians, with great steadiness, came to the very fence of the corral : but to their surprise they found the posts fastened together by iron nails instead of leather thongs, and, of course, in vain attempted to cut them with their knives. This saved the lives of the Christians : many of the wounded Indians were carried away by their companions ; and at last, one of the under caciques being wounded, the bugle sounded a retreat. They retired to their horses, and seemed to hold a council of war. This was an awful pause for the Spaniards, as all their ammunition, with the exception of a few cartridges, was expended. In an instant the Indians mounted their horses, and galloped out of sight. Another attack was still more quickly repulsed. A cool Frenchman managed the gun; he stopped till the Indians approached close, and then raked their line with grape- shot: ho thus laid thirty-nine of them on the ground; and, of course, siich a blow immediately routed the whole party. The town is indifferently called El Carmen or Patagones. It is built on the face of a cliff which fronts the river, and many of the houses are excavated even in the sandstone. The river is about two or three hundred yards wide, and is deep and rapid. The many islands, with their willow-trees, and the flat headlands, seen * The corral is an enclosure made of tall and strong stakes.

(Jl one behind the other on the northern boundary of the broad greeu valley, forms, by the aid of a bright sun, a view almost picturesque. The number of inhabitants does not exceed a few hundreds. These Spanish colonies do not, like our British ones, carry within them- selves the elements of growth. Many Indians of pure blood reside here : the tribe of the Cacique Lucanec constantly have their Toldos * on the outskirts of the town. The local government partly supplies them with provisions, by giving them all the old worn-out horses, and they earn a little by making horse-rugs and other articles of riding-gear. These Indians are considered civilized ; but what their character may have gained by a lesser degree of ferocity, is almost counterbalanced by their entire immorality. Some of the younger men are, however, improving ; they are willing to labour, and a short time since a party went on a sealing-voyage, and behaved very well. They were now enjoying the fruits of their labour, by being dressed in very gay, clean clothes, and by being very idle. The taste they showed in their dress was admir- able ; if you could have turned one of these young Indians into a statue of bronze, his drapery would have been perfectly graceful. One day I rode to a large salt-lake, or Salina, which is distant fifteen miles from the town. During the winter it consists of a shallow lake of brine, which in summer is converted into a h'eld of snow-white salt. The layer near the margin is from four to five inches thick, but towards the centre its thickness increases. This lake was two and a half miles long, and one broad. Others occur in the neighbourhood many times larger, and with a floor of salt, two and three feet in thickness, even when under water during the winter. One of these brilliantly white and level expanses, in the midst of the brown and desolate plain, offers an extraordinary spectacle. A large quantity of salt is annually drawn from the saliua : and great piles, some hundred tons in weight, were lying ready for exportation. The season for working the Salinas forms the harvest of Patagones; for on it the prosperity of the place depends. Nearly the whole population encamps on the bank of the river, and the people are employed in drawing out the salt in bullock-waggons. This salt is crystallized in great cubes, and is remarkably pure : Mr. Trenham Eeeks has kindly analyzed some for me, and he finds in it only 0'26 of gypsum and O22 of earthy matter. It is a singular fact, that it does not serve so well for * The hovels of the Indians are thus called. 62 KIO NEGRO. [ciur. iv. preserving meat as sea-salt from the Cape cle Verd islands ; and a merchant at Buenos Ayres told me that he considered it as fifty per cent, less valuable. Hence the Cape de Verd salt is constantly imported, and is mixed with that from these salinas. The purity of the Patagonian salt, or absence from it of those other saline bodies found in all sea-water, is the only assignable cause for this inferiority: a conclusion which no one, I think, would have suspected, but which is supported by the fact lately ascertained,* that those salts answer best for preserving cheese which contain most of the deliquescent chlorides. The border of the lake is formed of mud : and in this numerous large crystals of gypsum, some of which are three inches long, lie embedded; whilst on the surface others of sulphate of soda lie scattered about. The Gauchos call the former the " Padre del sal," and the latter the " Madre ; " they state that these progenitive salts always occur on the borders of the salinas, when the water begins to evaporate. The mud is black, and has a fetid odour. I could not at first imagine the cause of this, but I afterwards perceived that the froth which the wind drifted on shore was coloured green, as if by conferva : I attempted to carry home some of this green matter, but from an accident failed. Parts of the lake seen from a short distance appeared of a reddish colour, and this perhaps was owing to some infusorial anirnalcula. The mud in many places was thrown up by numbers of some kind of worm, or annelidous animal. How surprising it is that any creatures should be able to exist in brine, and that they should be crawling among crystals of sulphate of soda and lime! And what becomes of these worms when, during the long summer, the surface is hardened into a solid layer of salt ? Flamingoes in considerable numbers inhabit this lake, and breed here; throughout Patagonia, in Northern Chile, and at the Galapagos Islands, I met with these birds wherever there were lakes of brine. I saw them here wading about in search of food— probably for the worms which burrow in the mud ; and these latter probably feed on infusoria or conferva. Thus we have a little living world within itself, adapted to these inland lakes of brine. A minute crustaceous animal (Cancer salinus) is said f to * lleport of the Agricult. Chcra.

COLORADO. 63 live iu countless numbers in the brine-pans at Lyrniiigton : but only in those in which the fluid has attained, from evaporation, considerable strength — namely, about a quarter of a pound of salt to a pint of water. Well may we affirm that every part of the world is habitable ! Whether lakes of brine, or those subterranean ones hidden beneath volcanic mountains — warm mineral springs — the wide expanse and depths of the ocean — the upper regions of the atmosphere, and even the surface of perpetual snow — all support organic beings. To the northward of the Eio Negro, between it and the inhabited country near Buenos Ayres, the Spaniards have only one small settlement, recently established at Bahia Blanca. The distance in a straight line to Buenos Ayres is very nearly five hundred British miles. The wandering tribes of horse Indians, which have always occupied the greater part of this country, having of late much ' harassed the outlying estaneias, the government at Buenos Ayres equipped some time since an army under the command of General Rosas for the purpose of exterminating them. The troops were now encamped on the banks of the Colorado ; a river lying about eighty miles northward of the Rio Negro. "When General Rosas left Buenos Ayres he struck in a direct line across the unexplored plains : and as the country was thus pretty well cleared of Indians, he left behind him, at wide intervals, a small party of soldiers with a troop of horses (a posta), so as to be enabled to keep up a com- munication with the capital. As the Beagle intended to call at Bahia Blanca, I determined to proceed there by land ; and ulti- mately I extended my plan to travel the whole way by the postas to Buenos Ayres.

Iu both countries the salt-lakes occupy shallow depressions in the plains ; in both the mud on the borders is black and fetid ; beneath the crust of common salt, sulphate of soda or of magnesia occurs, imperfectly crystallized; and in both, the muddy s.md is mixed with lentils of gypsum. The Siberian salt-lakes are inhabited by small crustaccous animals ; and flamingoes (Edin. New Philos. Jour., Jan. 1830) likewise frequent them. As these circumstances, apparently HO trifling, occur in two distant continents, we may feel sure that they are the necessary results of common causes. — f?ec Pallas' 8 Travels, 1793 to 179-1, pp. 129-i:ji. 64: R. NEGRO TO R. COLORADO. [CIIAP. iv. have already said, is nearly eighty miles distant : and as we travelled slowly, we were two days and a half on the road. The whole line of country deserves scarcely a better name than that of a desert. Water is found only in two small wells; it is called fresh; but even at this time of the year, during the rainy season, it was quite brackish. In the summer this must be a distressing passage ; for now it was sufficiently desolate. The valley of the Eio Negro, broad as it is, has merely been excavated out of the sandstone plain ; for immediately above the bank on which the town stands, a level country commences, which is interrupted only by a few trifling valleys and depressions. Everywhere the landscape wears the same sterile aspect ; a dry gravelly soil supports tufts of brown withered grass, and low scattered bushes, armed with thorns. Shortly after passing the first spring we came in sight of a, famous tree, which the Indians reverence as the altar of Walleechu. It is situated on a high part of the plain, and hence is a landmark visible at a great distance. As soon as a tribe of Indians come in sight of it, they offer their adorations by loud shouts. The tree itself is low, much branched, and thorny : just above the root it has a diameter of about three feet. It stands by itself without any neighbour, and was indeed the first tree we saw ; afterwards we met with a few others of the same kind, but they were far from common. Being winter the tree had no leaves, but in their place numberless threads, by which the various offerings, such as cigars, bread, meat, pieces of cloth, etc., had been suspended. Poor Indians, not having anything better, only pull a thread out of their ponchos, and fasten it to the tree. Kicher Indians are accustomed to pour spirits and mate into a certain hole, and likewise to smoke upwards, thinking thus to afford all possible gratification to Wal- leechu. To complete the scene, the tree was surrounded by the bleached bones of horses which had been slaughtered as sacrifices. All Indians of every age and sex make their offerings ; they then think that their horses will not tire, and that they themselves shall be prosperous. The Gaucho who told me this, said that in the time of peace he had witnessed this scene, and that he and others used to wait till the Indians had passed by, for the sake of stealing from Walleechu the offerings. The Gauchos think that the Indians consider the tree as the god itself, but it seems far more probable that they regard it as the altar. The only cause which I can imagine for this choice, is its 1833.] PATAGONIAN HARES. 65 being a landmark in a dangerous passage. The Sierra de la Ventana is visible at an immense distance ; and a Gaucho told me that he was once riding with an Indian a few miles to the north of the Eio Colorado, when the Indian commenced making the same loud noise, which is usual at the first sight of the distant tree ; putting his hand to his head, and then pointing in the direction of the Sierra. Upon being asked the reason of this, the Indian said in broken Spanish, "First see the Sierra." About two leagues beyond this curious tree we halted for the night : at this instant an unfortunate cow was spied by the lynx-eyed Gauchos, who set off in full chase, and in a few minutes dragged her in with their lazos, and slaughtered her. We here had the four necessaries of life " en el campo," — pasture for the horses, water (only a muddy puddle), meat and firewood. The Gauchos were in high spirits at finding all these luxuries ; and we soon set to work at the poor cow. This was the first night which I passed under the open sky, with the gear of the recado for my bed. There is high enjoyment in the independence of the Gaucho life — to be able at any moment to pull up your horse, and say, " Here we will pass the night." The death-like stillness of the plain, the dogs keeping watch, the gipsy-group of Gauchos making their beds round the fire, have left in my mind a strongly-marked picture of this first night, which will never be forgotten. The next day the country continued similar to that above de- scribed. It is inhabited by few birds or animals of any kind. Occasionally a deer, or a Guanaco (wild Llama) may be seen ; but the Agouti (Cavia Patagonica) is the commonest quadruped. This animal here represents our hares. It differs, however, from that genus in many essential respects ; for instance, it has only three toes behind. It is also nearly twice tho size, weighing from twenty to twenty-five pounds. The Agouti is a true friend of tho desert ; it is a common feature in the landscape to see two or three hopping quickly one after the other in a straight line across these wild plains. They are found as far north as the Sierra Tapalguen (lat. 87° 30'), where the plain rather suddenly becomes greener and more humid ; and their southern limit is between Port Desire and St. Julian, where there is no change in the nature of the country. It is a singular fact, that although the Agouti is not now found as far south as Port St. Julian, yet that Captain Wood, in his voyage in 1670, talks of them as being numerous there. What cause can 66 RIO COLORADO. [CHAV. iv, have altered, ill a wide, uninhabited, and rarely-visited country, the range of an animal like this ? It appears also, from the number shot by Captain Wood in one day at Port Desire, that they must have been considerably more abundant there formerly than at present. Where the Bizcacha lives and makes its burrows, the Agouti uses them ; but where, as at Bahia Blanca, the Bizcacha is not found, the Agouti burrows for itself. The same thing occurs with the little owl of the Pampas (Athene cunicularia), which has so often been described as standing like a sentinel at the mouth of the burrows ; for in Banda Oriental, owing to the absence of the Bizcacha, it is obliged to hollow out its own habitation. The next morning, as we approached the Rio Colorado, the appearance of the country changed; we soon came on a plain covered with turf, which, from its flowers, tall clover, and little owls, resembled the Pampas. We passed also a muddy swamp of considerable extent, which in summer dries, and becomes incrusted with various salts ; and hence is called a salitral. It was covered by low succulent plants, of the same kind with those growing on the sea-shore. The Colorado, at the pass where we crossed it, is only about sixty yards wide ; generally it must be nearly double that width. Its course is very tortuous, being marked by willow- trees and beds of reeds : in a direct line the distance to the mouth of the river is said to be nine leagues, but by water twenty-five. We were delayed crossing in the canoe by some immense troops of mares, which were swimming the river in order to follow a division of troops into the interior. A more ludicrous spectacle I never beheld than the hundreds and hundreds of heads, all directed one way, with pointed ears and distended snorting nostrils, appearing just above the water like a great shoal of some amphibious animal. Mare's flesh is the only food which the soldiers have when on an expedition. This gives them a great facility of movement ; for the distance to which horses can be driven over these plains is quite surprising: I have been assured that an unloaded horse can travel a hundred miles a day for many days successively. The encampment of General Rosas was close to the river. It consisted of a square formed by waggons, artillery, straw huts, etc. The soldiers were nearly all cavalry ; and I should think such a villanous, banditti-like army was never before collected together. The greater number of men were of a mixed breed, between Negro, Indian, and Spaniard. I know not the reason, but men of such 1833.] ENCAMPMENT OF GENERAL ROSAS. 67 origin seldom have a good expression of countenance. I called on the Secretary to show my passport. He began to cross-question me in the most dignified and mysterious manner. By good luck I had a letter of recommendation from the government of Buenos Ayres * to the commandant of Patagones. This was taken to General Rosas, who sent me a very obliging message ; and the Secretary returned all smiles and graciousuess. We took up our residence in the rancho, or hovel, of a curious old Spaniard, who had served with Napoleon in the expedition against Russia. We stayed two days at the Colorado; I had little to do, for the .surrounding country was a swamp, which in summer (December), when the snow melts on the Cordillera, is overflowed by the river. My chief amusement was watching the Indian families as they camo to buy little articles at the rancho where wo stayed. It was sup- posed that General Rosas had about six hundred Indian allies. The men were a tall, fine race, yet it was afterwards easy to see in the Fuegian savage the same countenance rendered hideous by cold, want of food, and less civilization. Some authors, in defining the primary races of mankind, have separated these Indians into two classes ; but this is certainly incorrect. Among the young women or chinas, some deserve to be called even beautiful. Their hair was coarse, but bright and black ; and they wore it in two plaits hanging down to the waist. They had a high colour, and eyes that glistened with brilliancy; their legs, feet, and arms were small and elegantly formed ; their ankles, and sometimes their waists, were ornamented by broad bracelets of blue beads. Nothing could be more inter- esting than some of the family groups. A mother with one or two daughters would often come to our rancho, mounted on the sarno horse. They ride like men, but with their knees tucked up much higher. This habit, perhaps, arises from their being accustomed, when travelling, to ride the loaded horses. The duty of the women is to load and unload the horses ; to make the tents for the night ; in short to be, like the wives of all savages, useful slaves. The men fight, hunt, take care of the horses, and make the riding gear. One of their chief indoor occupations is to knock two stones together till they become round, in order to make the bolas. With this important weapon the Indian catches his game, and also his horse, * I am bound to express, in the strongest terms, my obligation to the Government of Buenos Ayres for the obliging manner in -which passports to all parts of the country were given me, as naturalist of the Beagle. 68 RIO COLORADO. [CHAP. iv. which roams free over the plain. In fighting, his first attempt is to throw down the horse of his adversary with the bolas, and when entangled by the fall to kill him with the chuzo. If the balls only catch the neck or body of an animal, they are often carried away and lost. As the making the stones round is the labour of two days, the manufacture of the balls is a very common employment. Several of the men and women had their faces painted red, but I never saw the horizontal bands which are so common among the Fuegians. Their chief pride consists in having everything made of silver ; I have seen a cacique with his spurs, stirrups, handle of his knife, and bridal made of this metal : the head-stall and reins being of wire, were not thicker than whipcord ; and to see a fiery steed wheeling about under the command of so light a chain, gave to the horsemanship a remarkable character of elegance. General Eosas intimated a wish to see me ; a circumstance which I was afterwards very glad of. He is a man of an extraordinary character, and has a most predominant influence in the country, which it seems probable he will use to its prosperity and advance- ment.* He is said to be the owner of seventy- four square leagues of land, and to have about three hundred thousand head of cattle. His estates are admirably managed, and are far more productive of corn than those of others. He first gained his celebrity by his laws for his own estancias, and by disciplining several hundred men, so as to resist with success the attacks of the Indians. There are many stories current about the rigid manner in which his laws were enforced. One of these was, that no man, on penalty of being put into the stocks, should carry his knife on a Sunday : this being the principal day for gambling and drinking, many quarrels arose, which from the general manner of fighting with the knife often proved fatal. One Sunday the Governor came in great form to pay the estancia a visit, and General Eosas, in his hurry, walked out to receive him with his knife, as usual, stuck in his belt. The steward touched his arm, and reminded him of the law; upon which turning to the Governor, he said he was extremely sorry, but that he must go into the stocks, and that till let out, he possessed no power even in his own house. After a little time the steward was persuaded to open the stocks, and to let him out, but no sooner was this done, than he turned to the steward and said, "You now have broken the laws, so you must take my place in the * This prophecy has turned out entirely and miserably wrong. 1845. - 1833.] GENERAL ROSAS. 69 stocks." Such actions as these delighted the Gauchos, who all possess high notions of their own equality and dignity. General Kosas is also a perfect horseman — an accomplishment of no small consequence in a country where an assembled army elected its general by the following trial : A troop of unbroken horses being driven into a corral, were let out through a gateway, above which was a cross-bar : it was agreed whoever should drop from the bar on one of these wild animals, as it rushed out, and should be able, without saddle or bridle, not only to ride it, but also to bring it back to the door of the corral, should be their general. The person who succeeded was accordingly elected ; and doubtless made a fit general for such an army. This extraordinary feat has also been performed by Eosas. By these means, and by conforming to the dress and habits of the Gauchos, he has obtained an unbounded popularity in the country, and in consequence a despotic power. I was assured by an English merchant, that a man who had murdered another, when arrested and questioned concerning his motive, answered, " He spoke disrespectfully of General Eosas, so I killed him." At the end of a week the murderer was at liberty. This doubtless was the act of the general's party, and not of the general himself. In conversation he is enthusiastic, sensible, and very grave. His gravity is carried to a high pitch: I heard one of his mad buffoons (for he keeps two, like the barons of old) relate the fol- lowing anecdote : " I wanted very much to hear a certain piece of music, so I went to the general two or three times to ask him ; he said to me, ' Go about your business, for I am engaged.' I went a second time ; he said, ' If you come again I will punish you.' A third time I asked, and he laughed. I rushed out of the tent, but it was too late ; he ordered two soldiers to catch and stake me. I begged by all the saints in heaven he would let me off; but it would not do ; — when the general laughs he spares neither mad man nor sound." The poor flighty gentleman looked quite dolorous, at the very recollection of the staking. This is a very severe punishment ; four posts are driven into the ground, and the man is extended by his arms and legs horizontally, and there left to stretch for several hours. The idea is evidently taken from the usual method of drying hides. My interview passed away without a smile, and I obtained a passport and order for the government post-horses, and this he gave me in the most obliging and ready manner. 70 RIO COLORADO. [CHAP. iv. lu the morning we started for Bahia Blanca, which we reached in two days. Leaving the regular encampment, we passed by the toldos of the Indians. These are round like ovens, and covered with hides ; by the month of each, a tapering chuzo was stuck in the ground. The toldos were divided into separate groups, which belonged to the different caciques' tribes, and the groups were again divided into smaller ones, according to the relationship of the owners. For several miles we travelled along the valley of the Colorado. The alluvial plains on the side appeared fertile, and it is supposed that they are well adapted to the growth of corn. Turning northward from the river, we soon entered on a country, differing from the plains south of the river. The land still con- tinued dry and sterile : but it supported many different kinds of plants, and the grass, though brown and withered, was more abun- dant, as the thorny bushes were less so. These latter in a short space entirely disappeared, and the plains were left without a thicket to cover their nakedness. This change in the vegetation marks the commencement of the grand calcareo argillaceous de- posit, which forms the wide extent of the Pampas, and covers the granitic rocks of Banda Oriental. From the Strait of Magellan to the Colorado, a distance of about eight hundred miles, the face of the country is everywhere composed of shingle: the pebbles are chiefly of porphyry, and probably owe their origin to the rocks of the Cordillera. North of the Colorado this bed thins out, and the pebbles become exceedingly small, and here the characteristic vegetation of Patagonia ceases. Having ridden about twenty-five miles, we came to a broad belt of sand-dunes, which stretches, as far as the eye can reach, to the cast and west, The sand-hillocks resting on the clay, allow small pools of water to collect, and thus afford in this dry country an invaluable supply of fresh water. The great advantage arising from depressions and elevations of the soil, is not often brought home to the mind. The two miserable springs in the long passage between the Piio Negro and Colorado were caused by trifling inequalities in the plain; without them not a drop of water would have been found. The belt of sand-dunes is about eight miles wide; at some former period, it probably formed the margin of a grand estuary, where the Colorado now flows. In this district, where absolute proofs of the recent elevation of the laud occur, such speculations can hardly bo neglected by any one, although 1833.] A NEGRO LIEUTENANT. 71 merely considering the physical geography of the country. Having crossed the sandy tract, we arrived in the evening at one of the post-houses ; and, as the fresh horses were grazing at a distance, we determined to pass the night there. The house was situated at the base of a ridge, between one and two hundred feet high — a most remarkable feature in this country. This posta was commanded by a negro lieutenant, born in Africa : to his credit be it said, there was not a ranche between the Colorado and Buenos Ayres in nearly such neat order as his. He had a little room for strangers, and a small corral for the horses, all made of sticks and reeds ; he had also dug a ditch round his house, as a defence in case of being attacked. This would, however, have been of little avail, if the Indians had come; but his chief comfort seemed to rest in the thought of selling his life dearly. A short time before, a body of Indians had travelled past in the night; if they had been aware of the posta, our black friend and his four soldiers would assuredly have been slaughtered. I did not any- where meet a more civil and obliging man than this negro ; it was therefore the more painful to see that he would not sit down and cat with us. In the morning we sent for the horses very early, and started for another exhilarating gallop. We passed the Cabeza del Buey, an old name given to the head of a large marsh, which extends from Bahia Blanca. Here we changed horses, and passed through some leagues of swamps and saline marshes. Changing horses for the last time, we again began wading through the mud. My animal .fell, and I was well soused in black mire — a very disagreeable accident, when one does not possess a change of clothes. Some miles from the fort we met a man, who told us that a great gun had been fired, which is a signal that Indians are near. We immediately left the road, and followed the edge of a marsh, which when chased offers the best mode of escape. "We were glad to arrive within the walls, when we found all the alarm was about nothing, for the Indians turned out to be friendly ones, who wished to join General Rosas. Bahia Blanca scarcely deserves the name of a village. A few houses and the barracks for the troops are enclosed by a deep ditch and fortified wall. The settlement is only of recent standing (since 1828) ; and its growth has been one of trouble. The govern- ment of Buenos Ayres unjustly occupied it by force, instead ot 72 BAHIA BLAXCA. [CHAP. iv. following the wise example of the Spanish Viceroys, who purchased the land near the older settlement of the Rio Negro, from the Indians. Hence the need of the fortifications; hence the few houses and little cultivated land without the limits of the walls ; even the cattle are not safe from the attacks of the Indians beyond the boundaries of the plain, on which the fortress stands. The part of the harbour where the Beagle intended to anchor being distant twenty-five miles, I obtained from the Commandant a guide and horses, to take me to see whether she had arrived. Leaving the plain of green turf, which extended along the course of a little brook, we soon entered on a wide level waste consisting either of sand, saline marshes, or bare rnud. Some parts were clothed by low thickets, and others with those succulent plants, which luxuriate only where salt abounds. Bad as the country was, ostriches, deer, agoutis, and armadilloes, were abundant. My guide told me, that two mouths before he had a most narrow escape of his life : he was out hunting with two other men, at no great distance from this part of the country, when they were suddenly met by a party of Indians, who giving chase, soon over- took and killed his two friends. His own horse's legs were also caught by the bolas ; but he jumped off, and with his knife cut them free : while doing this he was obliged to dodge round his horse, and received two severe wounds from their chuzos. Spring- ing on the saddle, he managed, by a most wonderful exertion, just to keep ahead of the long spears of his pursuers, who followed him to within sight of the fort. From that time there was an order that no one should stray far from the settlement. I did not know of this when I started, and was surprised to observe how earnestly my guide watched a deer, which appeared to have been frightened from a distant quarter. We found the Beagle had not arrived, and consequently set out on our return, but the horses soon tiring, we were obliged to bivouac on the plain. In the morning we had caught an armadillo, which, although a most excellent dish when roasted in its shell, did not make a very substantial breakfast and dinner for two hungry men. The ground at the place where we stopped for the night, was incrusted with a layer of sulphate of soda, and hence, of course, was without water. Yet many of the smaller rodents managed to exist even here, and the tucutuco was making its odd little grunt beneath my head, during half the night. Our horses were very 1833.] SALINE INCRUSTATIONS. 73 poor ones, and in the morning they were soon exhausted from not having had anything to drink, so that we were obliged to walk. About noon the dogs killed a kid, which we roasted. I ate some of it, but it made me intolerably thirsty. This was the more distressing as the road, from some recent rain, was full of little puddles of clear water, yet not a drop was drinkable. I had scarcely been twenty hours without water, and only part of the time under a hot sun, yet the thirst rendered me very weak. How people survive two or three days under such circumstances, I cannot imagine : at the same time, I must confess that my guide did not suffer at all, and was astonished that one day's deprivation should be so troublesome to me. . I have several times alluded to the surface of the ground being incrusted with salt. This phenomenon is quite different from that of the salinas, and more extraordinary. In many parts of South America, wherever the climate is moderately dry, these incrusta- tions occur ; but I have nowhere seen them so abundant as near Bahia Blanca. The salt here, and in other parts of Patagonia, consists chiefly of sulphate of soda with some common salt. As long as the ground remains moist in these salitrales (as the Spaniards improperly call them, mistaking this substance for saltpetre), nothing is to be seen but an extensive plain composed of a black, muddy soil, supporting scattered tufts of succulent plants. On returning through one of these tracts, after a week's hot weather, one is surprised to see square miles of the plain white, as if from a slight fall of snow, here and there heaped up by the wind into little drifts. This latter appearance is chiefly caused by the salts being drawn up, during the slow evaporation of the moisture, round blades of dead grass, stumps of wood, and pieces of broken earth, instead of being crystallized at the bottoms of the puddles of water. The salitrales occur either on level tracts elevated only a few feet above the level of the sea, or on alluvial land bordering rivers. M. Parchappe * found that the saline incrustation on the plain, at the distance of some miles from the sea, consisted chiefly of sulphate of soda, with only seven per cent, of common salt ; whilst nearer to the coast, the common salt in- creased to 37 parts in a hundred. This circumstance would tempt one to believe that the sulphate of soda is generated in the soil, * Voyage dans 1'Amerique Mcricl par M. A. d'Orbigny. Part. Hist. torn. i. p. CG4. 74 BAHIA BLAXCA. [CHAP. iv. from the muriate, left on the surface during the slow and recent elevation of this dry country. The whole phenomenon is well worthy the attention of naturalists. Have the succulent, salt- loving plants, which are well known to contain much soda, the power of decomposing the muriate ? Does the black fetid mud, abounding with organic matter, yield the sulphur and ultimately the sulphuric acid? Two days afterwards I again rode to the harbour : when not far from our destination, my companion, the same man as before, spied three people hunting on horseback. He immediately dismounted, and watching them intently, said, " They don't ride like Christians, and nobody can leave the fort." The three hunters joined com- pany, and likewise dismounted from their horses. At last one mounted again and rode over the hill out of sight. My companion said, " We must now get on our horses : load your pistol ; " and he looked to his own sword. I asked, "Are they Indians?" — " Quien sabe ? (who knows ?) if there are no more than three, it does not signify." It then struck me, that the one man had gone over the hill to fetch the rest of his tribe. I suggested this ; but all the answer I could extort was, "Quien sabe?" His head and eye never for a minute ceased scanning slowly the distant horizon. I thought his uncommon coolness too good a joke, and asked him why he did not retiirn home. I was startled when he answered, " We are returning, but in a line so as to pass near a swamp, into which we can gallop the horses as far as they can go, and then trust to our own legs ; so that there is no danger." I did not feel quite so confident of this, and wanted to increase onr pace. He said, " No, not until they do." When any little inequality con- cealed us, we galloped ; but when in sight, continued walking. At last we reached a valley, and turning to the left, galloped quickly to the foot of a hill ; ho gave me his horse to hold, made the dogs lie down, and then crawled on his hands and knees to reconnoitre. He remained in this position for some time, and at last, bursting out in laughter, exclaimed, " Mugeres ! " (women !) He knew them to bo the wife and sister-in-law of the major's son, hunting for ostrich's eggs. I have described this man's conduct, because ho acted under the full impression that they were Indians. As soon, however, as the absurd mistake was found out, he gave me a hun- dred reasons why they could not have been Indians ; but all these 1833.] ZOEILLOS. 75 were forgotten at the time. We then rode on in peace and quiet- ness to a, low point called Punta Alta, whence we could see nearly the whole of the great harbour of Bahia Blanca. The wide expanse of water is choked up by numeroxis great mud-banks, which the inhabitants call Cangrejales, or crabberies, from the number of small crabs. The mud is so soft that it is impossible to walk oyer them, even for the shortest distance. Many of the banks have their surfaces covered with long rushes, the tops of which alone are visible at high water. On one oc- casion, when in a boat, we were so entangled by these shallows that we could hardly find our way. Nothing was visible but the flat beds of mud ; the day was not very clear, and there was much refraction, or as the sailors expressed it, ''things loomed high." The only object within our view which was not level was tho horizon; rushes looked like bushes unsupported in the air, and water like mud-banks, and mud-banks like water. We passed the night in Punta Alta, and I employed myself in searching for fossil bones ; this point being a perfect catacomb for monsters of extinct races. The evening was perfectly calm and clear ; the extreme monotony of the view gave it an interest even in the midst of mud-banks and gulls, sand-hillocks and solitary vultures. In riding back in the morning we came across a very fresh track of a Puma, but. did not succeed in finding it. We saw also a couple of Zorillos, or skunks, — odious animals, which are far from uncommon. In general appearance the Zorillo resembles a polecat, but it is rather larger, and much thicker in proportion . Conscious of its power, it roams by day about the open plain, and fears neither dog nor man. If a dog is urged to the attack, its courage is instantly checked by a few drops of the fetid oil, which brings on violent sickness and running at the nose. Whatever is once polluted by it, is for ever useless. Azara says the smell can be perceived at a league distant ; more than once, when entering the harbour of Monte Video, the wind being off shore, we have per- ceived the odour on board the Beagle. Certain it is, that every animal most willingly makes room for the Zorillo. 76 BAHIA BLAXCA. [ciiAp. v.. CHAPTER V.

BAHIA BLANCA. THE Beagle arrived here on the 2ith of August, and a week after- wards sailed for the Plata. With Captain Fitz Boy's consent I was left behind, to travel by land to Buenos Ayres. I will here add some observations, which were made during this visit and on a previous occasion, when the Beagle was employed in surveying the harbour. The plain, at the distance of a few miles from the coast, belongs to the great Pampean formation, which consists in part of a reddish clay, and in part of a highly calcareous marly rock. Nearer the coast there are some plains formed from the wreck of the upper plain, and from mud, gravel, and sand thrown up by the sea during the slow elevation of the land, of which elevation we have evidence in upraised beds of recent shells, and in rounded pebbles of pumice scattered over the country. AtPunta Alta we have a section of one of these later-formed little plains, which is highly interesting from the number and extraordinary character of the remains of gigantic land-animals embedded in it. These have been fully described by Professor Owen, in the Zoology of the voyage of the Beagle, and are deposited in the College of Surgeons. I will here give only a brief outline of their nature. First, parts of three heads and other bones of the Megatherium, the huge dimensions of which are expressed by its name. Secondly, the Megalonyx, a great allied animal. Thirdly, the Scelidotherium, 1833.] EXTINCT QUADRUPEDS. 77 also an allied animal, of which I obtained a nearly perfect skeleton. It must have been as large as a rhinoceros : in the structure of its head it comes, according to Mr. Owen, nearest to the Cape Ant- eater, but in some other respects it approaches to the armadilloes. Fourthly, the Mylodon Darwinii, a closely related genus of little inferior size. Fifthly, another gigantic edental quadruped. Sixthly, a large animal, with an osseous coat in compartments, very like that of an armadillo. Seventhly, an extinct kind of horse, to which I shall have again to refer. Eighthly, a tooth of a Pachydermatous animal, probably the same with the Macrauchenia, a huge beast with a long neck like a camel, which I shall also refer to again. Lastly, the Toxodou, perhaps one of the strangest animals ever discovered : in size it equalled an elephant or megatherium, but the structure of its teeth, as Mr. Owen states, proves indisputably that it was intimately related to the Gnawers, the order which, at the present day, includes most of the smallest quadrupeds : in many details it is allied to the Pachydermata : judging from tho position of its eyes, ears, and nostrils, it was probably aquatic, like the Dugong and Manatee, to which it is also allied. How wonder- fully are the different Orders, at the present time so well separated, blended together in different points of the structure of the Toxodon ! The remains of these nine great quadrupeds, and many detached bones, were found embedded on the beach, within the space of about 200 yards square. It is a remarkable circumstance that so many different species should be found together ; and it proves how numerous in kind the ancient inhabitants of this country must have been. At the distance of about thirty miles from Punta Alta, in a cliff of red earth, I found several fragments of bones, some of large size. Among them were the teeth of a gnawer, equalling in size and closely resembling those of the Capybara, whose habits have been described ; and therefore, probably, an aquatic animal. There was also part of the head of a Ctenomys ; the species being different from the Tucutuco, but with a close general resemblance. The red earth, like that of the Pampas, in which these remains were embedded, contains, according to Professor Ehrenberg, eight fresh-water and one salt-water infusorial animalcule; therefore, probably, it was an estuary deposit. The remains at Punta Alta were embedded in stratified gravel and reddish mud, just such as the sea might now wash up on a shallow bank. They were associated with twenty-three species of 78 BAHIA BLANCA. [CHAP. v. shells, of which thirteen are recent and four others very closely related to recent forms.* From the bones of the Scelidotherium, including even the knee-cap, being intornbed in their proper relative positions, and from the osseous armour of the great arma- dillo-like animal being so well preserved, together with the bones of one of its legs, we may feel assured that these remains were fresh and united by their ligaments, when deposited in the gravel together with the shells, f Hence we have good evidence that the above enumerated gigantic quadrupeds, more different from those of the present day than the oldest of the tertiary quadrupeds of Europe, lived whilst the sea was peopled with most of its present inhabitants; and we have confirmed that remarkable law so often insisted on by Mr. Lyell, namely, that the " longevity of the species in the mammalia is upon the whole inferior to that of the testacea."t The great size of the bones of the Megatheroid animals, includ- ing the Megatherium, Megalonyx, Scelidotherium, and Mylodon, is truly wonderful. The habits of life of these animals were a complete puzzle to naturalists, until Professor Owen § solved the problem with remarkable ingenuity. The teeth indicate, by their simple structure, that these Megatheroid animals lived on vegetable food, and probably on the leaves and small twigs of trees ; their ponderous forms and great strong curved claws seem so little adapted for locomotion, that some eminent naturalists have actually believed, that, like the sloths, to which they are intimately related, they subsisted by climbing back downwards on trees, and feeding on the leaves. It was a bold, not to say preposterous, idea to con- ceive even antediluvian trees, with branches strong enough to bear animals as large as elephants. Professor Owen, with far more probability, believes that, instead of climbing on the trees, they * Since this was written, M. Alcide d'Orbigny Las examined these shells, and pronounces them all to be recent. t M. Aug. Bravard has described, in a Spanish work (' Observaciones Gcologicas,' 1857), this district, and he believes that the bones of the extinct mammals were washed out of the underlying Pampean deposit, and subsequently became embedded with the still existing shells ; but I am not convinced by his remarks. M. Bravard believes that the whole enormous Pampean deposit is a sub-aerial formation, like sand-dunes: this seems to me to be an untenable doctrine. t Principles of Geology, vol. iv. p. 40. § This theory was first developed in the Zoology of the Voyage of the Beagle, and subsequently in Professor Owen's 'Memoir on Mylodon robustus. J 1833.] FOOD OF LAKGE QUADRUPEDS. 70 pulled the branches down to them, and tore up the smaller ones by the roots, and so fed on the leaves. The colossal breadth and weight of their hinder quarters, which can hardly be imagined without having been seen, become, on this view, of obvious service, instead of being an incuinbrauce : their apparent clumsiness dis- appears. With their great tails and their huge heels firmly fixed like a tripod on the ground, they could freely exert the full force of their most powerful arms and great claws. Strongly rooted, indeed, must that tree have been, which could have resisted such force ! The Mylodon, moreover, was furnished with a long extensile tongue like that of the giraffe, which, by one of those beautiful provisions of nature, thus reaches with the aid of its long neck its leafy food. I may remark, that in Abyssinia the elephant, accord- ing to Bruce, when it cannot reach with its proboscis the branches, deeply scores with its tusks the trunk of the tree, up and down and all round, till it is sufficiently weakened to be broken down. The beds including the above fossil remains, stand only from fifteen to twenty feet above the level of high- water; and hence the elevation of the laud has been small (without there has been an intercalated period of subsidence, of which we have no evidence) since the great quadrupeds wandered over the surrounding plains ; and the external features of the country must then have been very nearly the same as now. What, it may naturally be asked, was the character of the vegetation at that period; was the country as wretchedly sterile as it now is? As so many of the co-embedded shells are the same with those now living in the bay, I was at first inclined to think that the former vegetation was probably similar to the existing one ; but this would have been an erroneous infer- ence, for some of these same shells live on the luxuriant coast of Brazil ; and generally, the character of the inhabitants of the sea are useless as guides to judge of those on the land. Nevertheless, from the following considerations, I do not believe that the simple fact of many gigantic quadrupeds having lived on the plains round Bahia Blanca, is any sure guide that they formerly were clothed with a luxuriant vegetation: I have no doubt that the sterile country a little southward, near the Kio Negro, with its scattered thorny trees, would support many and large quadrupeds. That large animals require a luxuriant vegetation, has been a general assumption which has passed from one work to another ; 80 BAHIA BLANCA. [CHAP. v. but I do not hesitate to say that it is completely false, and that it has vitiated the reasoning of geologists on some points of great interest in the ancient history of the world. The prejudice has probably been derived from India, and the Indian islands, where troops of elephants, noble forests, and impenetrable jungles, are associated together in every one's mind. If, however, we refer to any work of travels through the southern parts of Africa, we shall find allusions in almost every page either to the desert character of the country, or to the numbers of large animals inhabiting it. The same thing is rendered evident by the many engravings which have been published of ^various parts of the interior. When the Beagle was at Cape Town, I made an excursion of some days' length into the country, which at least was siifficient to render that which I had read more fully intelligible. Dr. Andrew Smith, who, at the head of his adventurous party, has lately succeeded in passing the Tropic of Capricorn, informs me that, taking into consideration the whole of the southern part of Africa, there can be no doubt of its being a sterile country. On the southern and south-eastern coasts there are some fine forests, but with these exceptions, the traveller may pass for days together through open plains, covered by a poor and scanty vegetation. It is difficult to convey any accurate idea of degrees of comparative fertility ; but it may be safely said that the amount of vegetation supported at any one time * by Great Britain, exceeds, perhaps even tenfold, the quantity on an equal area, in the interior parts of Southern Africa. The fact that bullock-waggons can travel in any direction, excepting near the coast, without more than occasionally half an hour's delay in cutting down bushes, gives, perhaps, a more definite notion of the scantiness of the vegetation. Now, if we look to the animals inhabiting these wide plains, we shall find their numbers extraordinarily great, and their bulk immense. We must enumerate the elephant, three species of rhinoceros, and probably, according to Dr. Smith, two others, the hippopotamus, the giraffe, the bos caffer— as large as a full-grown bull, and the elan— but little less, two zebras, and the quaccha, two gnus, and several antelopes even larger than these latter animals. It may be sup- posed that although the species are numerous, the individuals of each kind are few. By the kindness of Dr. Smith, I am enabled to * I mean by this to exclude the total amount which may have been successively produced and consumed during a given period. 1833.] FOOD OP LARGE QUADRUPEDS. 81 show that the case is very different. He informs me, that in lat. 24°, in one day's march with the bullock- waggons, lie saw, without wandering to any great distance on either side, between one hundred and one hundred and fifty rhinoceroses, which belonged to three species: the same clay he saw several herds of giraffes, amounting together to nearly a hundred ; and that although no elephant was observed, yet they arc found in this district. At the distance of a little more than one hour's march from their place of encampment on the previous night, his party actually killed at one spot eight hippopotamuses, and saw many more. In this same river there were likewise crocodiles. Of course it was a case quite extraordinary, to see so many great animals crowded together, but it evidently proves that they must exist in great numbers. Dr. Smith describes the country passed through that clay, as "b3inpj thinly covered with grass, and bushes about four feet high, and still more thinly with mimosa-trees." The waggons were not prevented travelling in a nearly straight line. Besides these large animals, every one the least acquainted with the natural history of the Cape, has read of the herds of antelopes, which can be compared only with the flocks of migratory birds. The numbers indeed of the lion, panther, and hysena, and the multitude of birds of prey, plainly speak of the abundance of tho smaller quadrupeds: one evening seven lions were counted at the same time prowling round Dr. Smith's encampment. As this able naturalist remarked to me, the carnage each day in Southern Africa must indeed be terrific ! I confess it is truly surprising how such a number of animals can find support in a country pro- ducing so little food. The larger quadrupeds no doubt roam over wide tracts in search of it ; and their food chiefly consists of under- wood, which probably contains much nutriment in a small bulk. Dr. Smith also informs me that the vegetation has a rapid growth ; no sooner is a part consumed, than its place is supplied by a fresh stock. There can be no doubt, however, that our ideas respecting the apparent amount of food necessary for the support of largo quadrupeds are much exaggerated : it should have been remembered that the camel, an animal of no mean bulk, has always been considered as the emblem of the desert. The belief that where large quadrupeds exist, tho vegetation must necessarily be luxuriant, is the more remarkable, because the converse is far from true. Mr. Burchell observed to me that when G 82 BAHIA BLANCA. [CHAP. v. entering Brazil, nothing struck him more forcibly than the splendour of the South American vegetation contrasted with that of South Africa, together with the absence of all large quadrupeds. In his Travels,* he has suggested that the comparison of the respective weights (if there were sufficient data) of an equal number of the largest herbivorous quadrupeds of each country would be extremely curious. If we take on the one side, the elephant, f hippopotamus, giraffe, bos caffer, elan, certainly three, and probably five species of rhinoceros ; and on the American side, two tapirs, the guanaco, three deer, the vicuna, peccari, capybara (after which we must choose from the monkeys to complete the number), and then place these two groups alongside each other, it is not easy to conceive ranks more disproportionate in size. After the above facts, we are compelled to conclude, against anterior probability,^: that among the mammalia there exists no close relation between the hulk of the species, and the quantity of the vegetation, in the countries which they inhabit. With regard to the number of large quadrupeds, there certainly exists no quarter of the globe which will bear comparison with Southern Africa. After the different statements which have been given, the extremely desert character of that region will not be disputed. In the European division of the world, we must look back to the tertiary epochs, to find a condition of things among the mammalia, resembling that now existing at the Cape of Good Hope. * Travels in the Interior of South Africa, vol. ii. p. 207. t The elephant which was killed at Exeter Change was estimated (being partly weighed) at five tons and a half. The elephant actress, as I was in- termed, weighed one ton less ; so that we may take five as the average of a full-grown elephant. I was told at the Surrey Gardens, that a hippopotamus which was sent to England cut up into pieces was estimated at three tons and a half; we will call it three. From these premises we may give three tons and a half to each of the five rhinoceroses ; perhaps a ton to the giraffe, and half to the bos caffer as well as to the elan (a large ox weighs from 1200 to 1500 pounds). This will give an average (from the above estimates) of 2-7 of a ton for the ten largest herbivorous animals of Southern Africa. In South America, allowing 1200 pounds for the two tapirs together, 550 for the guanaco and vicuna, 500 for three deer, 300 for the capybara, peccari, and a monkey, we shall have an average of 250 pounds, which I believe is overstating the result. The ratio will therefore be as 6048 to 250, or 24 to 1, for the ten largest animals from the two continents. % If we suppose the case of the discovery of a skeleton of a Greenland whale in a fossil state, not a single cetaceous animal being known to exist, what naturalist would have ventured conjecture on the possibility of a car- cass so gigantic being supported on the minute Crustacea and mollusca living in the frozen seas of the extreme North ? 1833.] SIBERIAN FOSSILS. 83 Those tertiary epochs, which we are apt to consider as abounding to an astonishing degree with large animals, because we find the remains of many ages accumulated at certain spots, could hardly boast of more large quadrupeds than Southern Africa does at present. If we speculate on the condition of the vegetation during those epochs, we are at least bound so far to consider existing analogies, as not to urge as absolutely necessary a luxuriant vegeta- tion, when we see a state of things so totally different at the Cape of Good Hope. We know * that the extreme regions of North America, many degrees beyond the limit where the ground at the depth of a few feet remains perpetually congealed, are covered by forests of large and tall trees. In a like manner, in Siberia, we have woods of birch, fir, aspen, and larch, growing in a latitude f (64°) where the mean temperature of the air falls below the freezing point, and where the earth is so completely frozen, that the carcass of an animal embedded in it is perfectly preserved. With these facts wo must grant, as far as quantity alone of vegetation is concerned, that the great quadrupeds of the later tertiary epochs might, in most parts of Northern Europe and Asia, have lived on the spots where their remains are now found. I do not here speak of the kind of vegetation necessary for their support ; because, as there is evidence of physical changes, and as the animals have become extinct, so may-we suppose that the species of plants have likewise been changed. These remarks, I may be permitted to add, directly bear on the case of the Siberian animals preserved in ice. The firm conviction of the necessity of a vegetation possessing a character of tropical luxuriance, to support such large animals, and the impossibility of reconciling this with the proximity of perpetual congelation, was one chief cause of the several theories of sudden revolutions of climate, and of overwhelming catastrophes, which were invented * See Zoological Remarks to Capt. Back's Expedition, by Dr. Richardson. He says, " The subsoil north of latitude 56° is perpetually frozen, the thaw on the coast not penetrating above three feet, and at Bear Lake, in latitude 64°, not more than twenty inches. The frozen substratum does not of itself destroy vegetation, for forests nourish on the suri'ace, at a distance from the coast." t See Hnmboldt, Fragmens Asiatiques, p. 38G : Barton's Geography of Plants : and Malte Brun. In the latter work it is said that the limit of the growth of trees in Siberia may be drawn under the parallel of 70°. 84: BAHIA BLANCA. [CHAP. v. to account for their entombment. I am far from supposing that the climate has not changed since the period when those animals lived, which now lie buried in the ice. At present I only wish to show, that as far as quantity of food alone is concerned, the ancient rhinoceroses might have roamed over the steppes of central Siberia (the northern parts probably being under water) even in their present condition, as well as the living rhinoceroses and elephants over the Karros of Southern Africa. I will now give an account of the habits of some of the rnoro interesting birds which are common on the wild plains of Northern Patagonia; and first for the largest, or South American ostrich. The ordinary habits of the ostrich are familiar to every one. They live on vegetable matter, such as roots and grass ; but at Bahia Blanca I have repeatedly seen three or four come down at low water to the extensive mud-banks which are then dry, for the sake, as the Gauchos say, of feeding on small fish. Although the ostrich in its habits is so shy, wary, and solitary, and although so fleet in its pace, it is caught without much difficulty by the Indian or Gaucho armed with the bolas. "When several horsemen appear in a semicircle, it becomes confounded, and does not know which way to escape. They generally prefer running against the wind ; yet at the first start they expand their wings, and like a vessel make all sail. On one fine hot day I saw several ostriches enter a bed of tall rushes, where they squatted concealed, till quite closely approached. It is not generally known that ostriches readily take to the water. Mr. King informs me that at the Bay of San Bias, and at Port Valdes in Patagonia, he saw these birds swimming several times from island to island. They ran into the water both when driven down to a point, and likewise of their own accord when not frightened : the distance crossed was about two hundred yards. When swimming, very little of their bodies appear above water ; their necks are extended a little forward, and their progress is slow. On two occasions I saw some ostriches swimming across the Sania Cruz river, where its course was about four hundred yards wide, and the stream rapid. Captain Sturt,* when descending the Mur- rumbidgee, in Australia, saw two emus in the act of swimming. The inhabitants of the country readily distinguish, even at a distance, the cock bird from the hen. The former is larger and * Shirt's Travels, vol. ii. p. 74. 1833.] SOUTH AMERICAN OSTRICH. 85 darker-coloured,* and has a bigger head. The ostrich, I believe the cock, emits a singular, deep-toned, hissing note : when first I heard it, standing in the midst of some sand-hillocks, I thought it was made by some wild beast, for it is a sound that one cannot tell whence it conies, or from how far distant. When we were at Bahia Blanca in the months of September and October, the eggs, in extraordinary numbers, were found all over the country. They lie either scattered and single, in which case they are never hatched, and are called by the Spaniards huachos ; or they are collected together into a shallow excavation, which forms the nest. Out of the four nests which I saw, three contained twenty-two eggs each, and the fourth twenty-seven. In one day's hunting on horseback sixty-four eggs were found ; forty-four of these were in two nests, and the remaining twenty, scattered huachos. The Gauchos unanimously affirm, and there is no reason to doubt their statement, that the male bird alone hatches the eggs, and for some time after- wards accompanies the young. The cock when on the nest lies very close; I have myself almost ridden over one. It is asserted that at such times they are occasionally fierce, and even dangerous, and that they have been known to attack a man on horseback, trying to kick and leap on him. My informer pointed out to me an old man, whom he had seen much terrified by one chasing him. I observe in Burchell's travels in South Africa, that he remarks, " Having killed a male ostrich, and the feathers being dirty, it was said by the Hottentots to be a nest bird." I understand that the male emu in the Zoological Gardens takes charge of the nest : this habit, therefore, is common to the family. The Gauchos unanimously affirm that several females lay in one nest. I have been positively told that four or five hen birds have been watched to go in the middle of the day, one after the other, to the same nest. I may add, also, that it is believed in Africa, that two or more females lay in one nest.f Although this habit at first appears very strange, I think the cause may be explained in a simple manner. The number of eggs in the nest varies from twenty to forty, and even to fifty ; and according to Azara, some- times to seventy or eighty. Now, although it is most probable, from the number of eggs found in one district being so extra- * A Gaucho assured me that he had once seen a snow- white or Albiue variety, and that it was a most beautiful bird. , f Burchell's Travels, vol. i. p. 280. 86 liAIIIA BLAXCA. [CHAP. v. ordinarily great in proportion to the parent birds, and likewise from the state of the ovarium of the hen, that she may in the course of the season lay a large number, yet the time required must be very long. Azara states,* that a female in a state of domestication laid seventeen eggs, each at the interval of three days one from another. If the hen was obliged to hatch her own eggs, before the last was laid the first probably would be addled ; but if each laid a few eggs at successive periods, in different nests, and several hens, as is stated to be the case, combined together, then the eggs in one collection would be nearly of the same age. If the number of eggs in one of these nests is, as I believe, not greater on an average than the number laid by one female in the season, then there must be as many nests as females, and each cock bird will have its fair share of the labour of incubation; and that during a period when the females probably could not sit, from not having finished laying.f I have before mentioned the great numbers of huachos, or deserted eggs; so that in one day's hunting twenty were found in this state. It appears odd that so many should be wasted. Does it not arise from the difficulty of several females associating together, and finding a male ready to undertake the office of incubation ? It is evident that there must at first be some degree of association between at least two females ; otherwise the eggs would remain scattered over the wide plains, at distances far too great to allow of the male collecting them into one nest : some authors have believed that the scattered eggs were deposited for the young birds to feed on. This can hardly be the case in America, because the huachos, although often found addled and putrid, arc generally whole. "When at the Kio Negro in Northern Patagonia, I repeatedly heard the Gauchos talking of a very rare bird which they called Avestruz Petise. They described it as being less than the common ostrich (which is there abundant), but with a very close general resem- blance. They said its colour was dark and mottled, and that its legs were shorter, and feathered lower down than those of the common ostrich. It is more easily caught by the bolas than the * Azara, vol. iv.-p. 173. t Lichtenstein, however, asserts (Travels, vol. ii. p. 25) that the hens begin sitting when they have laid ten or twelve eggs ; and that they con- tinue laying, I presume, in another nest. This appears to me very im- probable. He asserts that four or five hens associate for incubation with one cock, who sits only at night. 1833.] THE AVESTKUZ PETISE. 87 other species. The few inhabitants who had seen both kinds, affirmed they could distinguish them apart from a long distance. The eggs of tho small species appeared, however, more generally known ; and it was remarked, with surprise, that they were very little less than those of the Ehea, but of a slightly different form, and with a tinge of pale blue. This species occurs most rarely on the plains bordering the Eio Negro ; but about a degree and a half further south they are tolerably abundant. When at Port Desire, in Patagonia (lat. 48°), Mr. Martens shot an ostrich ; and I looked at it, forgetting at the moment, in the most unaccountable manner, the whole subject of the Petiscs, and thought it was a not full- grown bird of the common sort. It was cooked and eaten before my memory returned. Fortunately the head, neck, legs, wings, many of the larger feathers, and a large part of the skin, had been pre- served; and from these a very nearly perfect specimen has been put together, and is now exhibited in the museum of the Zoological Society. Mr. Gould, in describing this new species, has done me the honour of calling it after my name. Among the Patagonian Indians in the Strait of Magellan, we found a half Indian, who had lived some years with the tribe, but had been born in the northern provinces. I asked him if he had ever heard of the Avestruz Petise ? He answered by saying, " Why, there are none others in these southern countries." He informed me that the number of eggs in the nest of the petise is considerably less than in that of the other kind, namely, not more than fifteen on an average; but he asserted that more than one female de- posited them. At Santa Cruz we saw several of these birds. They were excessively wary : I think they could see a person approaching when too far off to be distinguished themselves. In ascending the river few were seen ; but in our quiet and rapid descent, many, in pairs and by fours or fives, were observed. It was remarked that this bird did not expand its wings, when first starting at full speed, after the manner of the northern kind. In conclusion I may observe, that the Struthio rhea inhabits the country of La Plata as far as a little south of the Eio Negro in lat. 41°, and that the Struthio Darwiuii takes its place in Southern Patagonia ; the part about the Eio Negro being neutral territory. M. A. d'Orbigny,* * When at the Kio Negro, \ve heard much of the indefatigable labours of this naturalist. M. Alcide d'Orbigny, during the years 1825 to 183B, traversed several large portions of South America, and has made a collec- 88 BAHIA I3LAXCA. [CHAP. v. when at the Ivio Negro, made great exertions to procure this bird, but never had the good fortune to succeed. Dobrizhoffer * long ago was aware of there being two kinds of ostriches; he says, "You must know, moreover, that Emus differ in size and habits in dif- ferent tracts of land ; for those that inhabit the plains of Buenos Ayres and Tucuman are larger, and have black, white, and gray feathers ; those near to the Strait of Magellan are smaller and more beautiful, for their white feathers are tipped with black at the extremity, and their black ones in like manner terminate in white." A very singular little bird, Tinochorus rumicivorus, is here common : in its habits and general appearance, it nearly equally partakes of the characters, different as they are, of the quail and snipe. The Tinochorus is found in the whole of southern South America, wherever there are sterile plains, or open dry pasture land. It frequents in pairs or small flocks the most desolate places, where scarcely another living creature can exist. Upon being approached they squat close, and then are very difficult to be dis- tinguished from the ground. When feeding they walk rather slowly, with their legs wide apart. They dust themselves in roads and sandy places, and frequent particular spots, where they may be found day after day : like partridges, they take wing in a flock. In all these respects, in the muscular gizzard adapted for vegetable food, in the arched beak and fleshy nostrils, short legs and form of foot, the Tinochorus has a close affinity with quails. But as soon as the bird is seen flying, its whole appearance changes ; the long pointed wings, so different from those in the gallinaceous order, the irregular manner of flight, and plaintive cry uttered at the moment of rising, recall the idea of a snipe. The sportsmen of the Beagle unanimously called it the short-billed snipe. To this genus, or rather to the family of the Waders, its skeleton shows that it is really related. The Tinochorus is closely related to some other South American birds. Two species of the genus Attagis are in almost every respect ptarmigans in their habits ; one lives in Tierra del Fuego, lion, and is now publishing the results on a scale of magnificence, which at once places himself in the list of American travellers second only to Humboldt. * Account of the Abiponee, A.D. 17-19, vol. i. (English translation) 1833.] THE OVEX-TJIBD. 89 above the limits of the forest land; and the other just beneath the siiow-liue on the Cordillera of Central Chile. A bird of another closely allied genus, Chionis alba, is an inhabitant of the antarctic regions ; it feeds on sea- weed and shells on the tidal rocks. Although not web-footed, from some unaccountable habit, it is frequently met with far out at sea. This small family of birds is one of those which, from its varied relations to other families, although at present offering only difficulties to the systematic naturalist, ulti- mately may assist in revealing the grand scheme, common to the present and past ages, on which organized beings have been created. The genus Furnarius contains several species, all small birds, living on the ground, and inhabiting open dry countries. In structure they cannot be compared to any European form. Or- nithologists have generally included them among the creepers, although opposed to that family in every habit. The best known species is the common oven-bird of La Plata, the Casara or house- maker of the Spaniards. The nest, whence it takes its name, is placed in the most exposed situations, as on the top of a post, a bare rock, or on a cactus. It is composed of niud and bits of straw, raid has strong thick walls : in shape it precisely resembles an oven, or depressed beehive. The opening is large and arched, and directly in front, within the nest, there is a partition, which reaches nearly to the roof, thus forming a passage or antechamber to the true nest. Another and smaller species of Furnarius (F. cunicularius), resembles the oven-bird in the general reddish tint of its plumage, in a peculiar shrill reiterated cry, and in an odd manner of running by starts. From its affinity, the Spaniards call it Casarita (or little housebuilder), although its nidification is quite different. The Casarita builds its nest at the bottom of a narrow cylindrical hole, which is said to extend horizontally to nearly six feet under .ground. Several of the country people told me, that when boys, they had attempted to dig out the nest, but had scarcely ever succeeded in getting to the end of the passage. The bird chooses any low bank of firm, sandy soil by the side of a road or stream. Here (at Bahia Blanca) the walls round the houses are built of hardened mud ; and I noticed that one, which enclosed a courtyard where I lodged, was bored through by round holes in a score of places. On asking the owner the cause of this, he bitterly com- plained of the little casarita, several of which I afterwards observed 90 BAHIA BLAXCA. [CHAP. v. at work. It is rather curious to find how incapable these birds must be of acquiring any notion of thickness, for although they were constantly flitting over the low wall, they continued vainly to bore through it, thinking it an excellent bank for their nests. I do not doubt that each bird, as often as it came to daylight on the opposite side, was greatly surprised at the marvellous fact. I have already mentioned nearly all the mammalia common in this country. Of armadilloes three species occur, namely, the Dasypus minutus or pichy, the D. villosus or pelitdo, and the apar. The first extends ten degrees further south than any other kind : a fourth species, the Mulita, does not come as far south as Bahia Blanca. The four species have nearly similar habits ; the peludo, however, is nocturnal, while the others wander by day over the open plains, feeding on beetles, larvae, roots, and even small snakes. The apar, commonly called mataco, is remarkable by having only three moveable bands; the rest of its tesselated covering being nearly inflexible. It has the power of rolling itself into a perfect sphere, like one kind of English woodlouse. In this state it is safe from the attack of dogs ; for the dog not being able to take the whole in its mouth, tries to bite one side, and the ball slips away. The smooth hard covering of the mataco offers a better defence than tbe sharp spines of the hedgehog. The pichy prefers a very dry soil; and the sand-dunes near the coast, where for many months it can never taste water, is its favourite resort : it often tries to escape notice, by squatting close to the ground. In the course of a day's ride, near Bahia Blanca, several were generally met with. The instant one was perceived, it was necessary, in order to catch it, almost to tumble off one's horse ; for in soft soil the animal burrowed so quickly, that its hinder quarters would almost disappear before one could alight. It seems almost a pity to kill such nice little animals, for as a Gaucho said, while sharpening his knife on the back of one, " Son tan mansos " (they are so quiet). Of reptiles there are many kinds: one snake (a Trigonocephalus, or Cophias *), from the size of the poison channel in its fangs, must be very deadly. Cuvier, in opposition to some other naturalists, makes this a sub-genus of the rattlesnake, and intermediate between it and the viper. In confirmation of this opinion, I observed a fact, which appears to me very curious and instructive, as showing how every character, even though it may be in some * M. Bibron calls it T. crepitans. A CUKIOUS 'TOAD. 91 degree independent of structure, has a tendency to vary by slow degrees. The extremity of the tail of this snake is terminated by a point, which is very slightly enlarged ; and as the animal glides along, it constantly vibrates the last inch ; and this part striking against the dry grass and brushwood, produces a rattling noise, which can be distinctly heard at the distance of six feet. As often as the animal was irritated or surprised, its tail was shaken ; and the vibrations were extremely rapid. Even as long as the body retained its irritability, a tendency to this habitual movement was evident. This Trigonocephalus has, therefore, in some respects the structure of a viper, with the habits of a rattlesnake: the noise, however, being produced by a simpler device. The ex- pression of this snake's face was hideous and fierce ; the pupil consisted of a vertical slit in a mottled and coppery iris ; the jaws were, broad at the base, and the nose terminated in a triangular projection. I do not think I ever saw anything more ugly, ex- cepting, perhaps, some of the vampire bats. I imagine this repiil- sive aspect originates from the features being placed in positions, with respect to each other, somewhat proportional to those of the human face ; and thus we obtain a scale of hideousness. Amongst the Eatrachian reptiles, I found only one little toad (Phryniscus nigricans), which was most singular from its colour. If we imagine, first, that it had been steeped in the blackest ink, and then, when dry, allowed to crawl over a board, freshly painted with the brightest vermilion, so as to colour the soles of its feet and parts of its stomach, a good idea of its appearance will be gained. If it had been an unnamed species, surely it ought to have been called Diabolicus, for it is a fit toad to preach in the ear of Eve. Instead of being nocturnal in its habits, as other toads are, and living in damp obscure recesses, it crawls during the heat of the day about the dry sand-hillocks and arid plains, where not a single drop of water can be found. It must necessarily depend on the dew for its moisture ; and this probably is absorbed by the skin, for it is known, that these reptiles possess great powers of cutaneous absorption. At Maldonado, I found one in a situation nearly as dry as at Bahia Blanca, and thinking to give it a great treat, carried it to a pool of water ; not only was the little animal Tinable to swim, but, I think without help it would soon have been drowned. Of lizards there were many kinds, but only one (Proctotretus 92 BAHIA BLAXCA. [CHAP. v. multimaculatus) remarkable from its habits. It lives ou the bare sand near the sea coast, and from its mottled colour, the brownish scales being speckled with white, yellowish red, and dirty blue, can hardly be distinguished from the surrounding surface. When frightened, it attempts to avoid discovery by feigning death, with outstretched legs, depressed body, and closed eyes: if further molested, it buries itself with great quickness in the loose sand. This lizard, from its flattened body and short legs, cannot run quickly. I will here add a few remarks on the hibernation of animals in this part of South America. When we first arrived at Bahia Blanca, September 7th, 1832, we thought nature had granted scarcely a living creature to this sandy and dry country. By digging, however, in the ground, several insects, large spiders, and lizards were found in a half-torpid state. On the 15th, a few animals began to appear, and by the 18th (three days from the equinox), everything announced the commencement of spring. The plains were ornamented by the flowers of a pink wood-sorrel, wild peas, cenotherse, and geraniums ; and the birds began to lay their eggs. Numerous Lainellicorn and Heteromerous insects, the latter remarkable for their deeply sculptured bodies, were slowly crawling about; while the lizard tribe, the constant inhabitants of a sandy soil, darted about in every direction. During the first eleven days, whilst nature was dormant, the mean temperature taken from observations made every two hours on board the Beagle, was 51° ; and in the middle of the day the thermometer seldom ranged above 55°. On the eleven succeeding days, in which all living things became 'so animated, the mean was 58°, and the range in the middle of the day between 60° and 70°. Here, then, an increase of seven degrees in mean temperature, but a greater one of extreme heat, was sufficient to awake the functions of life. At Monte Video, from which we had just before sailed, in the twenty-three days included between the 26th of July and the 19th of August, the mean temperature from 276 observations was 58°'4; the mean hottest day being 65°'5, and the coldest 46°. The lowest point to which the thermometer fell was 410>5, and occa- sionally in the middle of the day it rose to 69° or 70°. Yet with this high temperature, almost every beetle, several genera of spiders, snails, and land-shells, toads and lizards were all lying- torpid beneath stones. But we have seen that at Bahia Blanca, 1833.] SEA-PEN. 93 •which is four degrees southward, and therefore with a climate only a very little colder, this same temperature with a rather less ex- treme heat, was sufficient to awake all orders of animated beings. This shows how nicely the stimulus required to arouse hybernating animals is governed by the usual climate of the district, and not by the absolute heat. It is well known that within the tropics, the hybernation, or more properly aestivation, of animals is deter- mined not by the temperature, but by the times of drought. Near Eio de Janeiro, I was at first surprised to observe, that, a few days after some little depressions had been filled with water, they were peopled by numerous full-grown shells and beetles, which must have been lying dormant. Humboldt has related the strange accident of a hovel having been erected over a spot where a young crocodile lay buried in the hardened mud. He adds, "The Indians often find enormous boas, which they call Uji, or water serpents, in the same lethargic state. To reanimate them, they must bo irritated or wetted with water." I will only mention one other animal, a zoophyte (I believe Virgularia Patagonica), a kind of sea-pen. It consists of a thin, straight, fleshy stem, with alternate rows of polypi on each side, and surrounding an elastic stony axis, varying in length from eight inches to two feet. The stem at one extremity is truncate, but at the other is terminated by a vermiform fleshy appendage. The stony axis which gives strength to the stem may be traced at this extremity into a mere vessel filled with granular matter. At low water hundreds of these zoophytes might be seen, projecting like stubble, with the truncate end upwards, a few inches above tho surface of the muddy sand. When touched or pulled they suddenly drew themselves in with force, so as nearly or quite to disappear. By this action, the highly elastic axis must be bent at the lower extremity, where it is naturally slightly curved; and I imagine it is by this elasticity alone that the zoophyte is enabled to rise again through the mud. Each polypus, though closely united to its brethren, has a distinct mouth, body, and tentacula. Of these polypi, in a large specimen, there must be many thousands ; yet we see that they act by one movement: they have also one central axis connected with a system of obscure circulation, and the ova are produced in an organ distinct from the separate individuals.* * The cavities leading from the fleshy compartments of the extremity, •were filled with a yellow pulpy matter, which, examined under a micro- 94 BAHIA BLANCA. [CHAP. v. "Well may one be allowed to ask, what is an individual? It is always interesting to discover the foundation of the strange tales of the old voyagers ; and I have no doubt but that the habits of this Virgularia explain one such case. Captain Lancaster, in his voyage * in 1601, narrates that on the sea-sands of the Island of Sombrero, in the East Indies, he " found a small twig growing up like a young tree, and on offering to pluck it up it shrinks down to the ground, and sinks, unless held very hard. On being plucked up, a great worm is found to be its root, and as the tree groweth in greatness, so doth the worm diminish ; and as soon as the worm is entirely turned into a tree it rooteth in the earth, and so becomes great. This transformation is one of the strangest wonders that I saw in all my travels : for if this tree is plucked up, while young, and the leaves and bark stripped off, it becomes a hard stone when dry, much like white coral : thus is this worm twice transformed into different natures. Of these we gathered and brought home many." During my stay at Bahia Blanca, "while waiting for the Beagle, the place was in a constant state of excitement, from rumours of wars and victories, between the troops of Rosas and the wild Indians. One day an account came that a small party forming one of the postas on the line to Buenos Ayres, had been found all murdered. The next day three hundred men arrived from the Colorado, under the command of Commandant Miranda. A large portion of these men were Indians (mansos, or tame), belonging to the tribe of the Cacique Bernantio. They passed the night here ; and it was impossible to conceive anything more wild and savage scope, presented an extraordinary appearance. The mass consisted of rounded, semi-transparent, irregular grains, aggregated together into par- ticles of various sizes. All such particles, and the separate grains, possessed the power of rapid movement; generally revolving around different axes, but sometimes progressive. The movement was visible with a very weak power, but even with the highest its cause could not be perceived. It was very different from the circulation of the fluid in the elastic bag, containing the thin extremity of the axis. On other occasions, when dissecting small marine animals beneath the microscope, I have seen particles of pulpy matter, some of large size, as soon as they were disengaged, commence revolving. I have imagined, I know not with how much truth, that this granulo-pulpy matter was in process of being converted into ova. Certainly in this zoophyte such appeared to be the case. * Kerr's Collection of Voyages, vol. viii. p. 119. 1833.] EXPEDITION AGAINST THE INDIANS. 95 than the scene of their bivouac. Some drank till they were intoxicated; others swallowed the steaming blood of the cattle slaughtered for their suppers, and then, being sick from drunken- ness, they cast it up again, and were besmeared with filth and gore. Nam sitmil expletus dapibus, vinoque sepultus Cervictsn inflexain posuit, jacuitque per antrtim Immensus, saniera crucians, ac frusta cruenta Per sonmura commixta mem. In the morning they started for the scene of the murder, with orders to follow the " rastro," or track, even if it led them to Chile. We subsequently heard that the wild Indians had escaped into the great Pampas, and from some cause the track had been missed. One glance at the rastro tells these people a whole history. Sup- posing they examine the track of a thousand horses, they will soon guess the number of mounted ones by seeing how many have cantered; by the depth of the other impressions, whether any horses were loaded with cargoes ; by the irregularity of the foot- steps, how far tired ; by the manner in which the food has been cooked, whether the pursued travelled in haste; by the general appearance, how long it has been since they passed. They con- sider a rastro of ten days or a fortnight, quite recent enough to be hunted out. We also heard that Miranda struck from the west end of the Sierra Ventana, in a direct line to the island of Chole- chel, situated seventy leagues up the Eio Negro. This is a distance of between two and three hundred miles, through a country completely unknown. What other troops in the world are so independent ? With the sun for their guide, mare's flesh for food, their saddle-cloths for beds, — as long as there is a little water, these men would penetrate to the end of the world. A few days afterwards I saw another troop of these banditti-like soldiers start on an expedition against a tribe of Indians at the small Salinas, who had been betrayed by a prisoner cacique. The Spaniard who brought the orders for this expedition was a very intelligent man. He gave me an account of the last engagement at which he was present. Some Indians, who had been taken prisoners, gave information of a tribe living north of the Colorado. Two hundred soldiers were sent; and they first discovered the Indians by a cloud of dust from their horses' feet, as they chanced to be travelling. The country was mountainous and wild, and it 96 BAHIA BLANCA. [CHAP. v. must have been far in tho interior, for the Cordillera were in sight. The Indians, men, women, and children, were about one hundred and ten in number, and they were nearly all taken or killed, for the soldiers sabre every man. The Indians are now so terrified that they offer no resistance in a body, but each flies, neglecting even his wife and children; but when overtaken, like wild animals, they fight against any number to the last moment. One dying Indian seized with his teeth the thumb of his adversary, and allowed his own eye to be forced out sooner than relinquish his hold. Another, who was wounded, feigned death, keeping a knife ready to strike one more fatal blow. My informer said, when lie was pursuing an Indian, the man cried out for mercy, at the •same time that he was covertly loosing the bolas from his waist, meaning to whirl it round his head and so strike his pursuer. " I however struck him with ray sabre to the ground, and then got off my horse, and cut his throat with my knife." This is a dark picture ; but how much more shocking is the unquestionable fact, that all the women who appear above twenty years old are massacred in cold blood ! When I exclaimed that this appeared rather inhuman, he answered, " Why, what can be done ? they 1 treed so!" Every one here is fully convinced that this is the most just war, because it is against barbarians. Who "would believe in this age that such atrocities could be committed in a Christian civilized country? The children of the Indians are saved, to be sold or given away as servants, or rather slaves for as long a time as the owners can make them believe themselves slaves ; but I believe in their treatment there is little to complain of. In the battle four men ran away together. They were pursued, one was killed, and the other three were taken alive. They turned out to be messengers or ambassadors from a large body of Indians, united in the common cause of defence, near the Cordillera. Tho tribe to which they had been sent was on the point of holding a grand council ; the feast of mare's flesh was ready, and the dance prepared : in the morning the ambassadors were to have returned to the Cordillera. They were remarkably fine men, very fair, above six feet high, and all under thirty years of age. The three survivors of course possessed very valuable information; and to extort this they were placed in a line. Tho two first being questioned, answered, " No se " (I do not know), and were one 1833.] CAPTIVE INDIANS. 97 after the other shot. The third also said " No se ; " adding, " Fire, I am a man, and can die ! " Not one syllable would they breathe to injure the united cause of their country ! The conduct of the above-mentioned cacique was very different ; he saved his life by betraying the intended plan of warfare, and the point of union in the Andes. It was believed that there were already six or seven hundred Indians together, and that in summer their numbers would be doubled. Ambassadors were to have been sent to the Indians at the small Salinas, near Bahia Blanca, whom I have mentioned that this same cacique had betrayed. The communica- tion, therefore, between the Indians, extends from the Cordillera to the coast of the Atlantic. General Eosas's plan is to kill all stragglers, and having driven the remainder to a common point, to attack them in a body, in the summer, with the assistance of the Chilenos. This operation is to be repeated for three successive years. I imagine the summer is chosen as the time for the main attack, because the plains are then without water, and the Indians can only travel in particular direc- tions. The escape of the Indians to the south of the Eio Negro, where in such a vast unknown country they would be safe, is pre- vented by a treaty with the Tehuelches to this effect ; — that Eosas pays them so nmch to slaughter every Indian who passes to the south of the river, but if they fail in so doing, they themselves are to be extirminated. The war is waged chiefly against the Indians near the Cordillera ; for many of the tribes on this eastern side are fighting with Kosas. The general, however, like Lord Chesterfield, thinking that his friends may in a future day become his enemies, always places them in the front ranks, so that their numbers may be thinned. Since leaving South America we have heard that this war of extermination completely failed. Among the captive girls taken in the same engagement, there were two very pretty Spanish ones, who had been carried away by the Indians when young, and could now only speak the Indian tongue. From their account they must have come from Salta, a distance in a straight line of nearly one thousand miles. This gives one a grand idea of the immense territory over which the Indians roam : yet, great as it is, I think there will not, in another half-century, be a wild Indian northward of the Eio Negro. The warfare is too bloody to last ; the Christians killing every Indian, and the Indians doing the same by the Christians. It is melan- H 98 BAHIA BLANCA. [CHAP. v. choly to trace liow the Indians have given way before the Spanish invaders. Schirdel* says that in 1535, when Buenos Ayres was founded, there were villages containing two and three thousand in- habitants. Even in Falconer's time (1750) the Indians made inroads as far as Luxan, Areco, and Arrecife, but now they are driven beyond the Salado. Not only have whole tribes been exterminated, but the remaining Indians have become more barbarous : instead of living in large villages, and being employed in the arts of fishing, as well as of the chase, they now wander about the open plains, without home or fixed occupation. I heard also some account of an engagement which took place, a few weeks previously to the one mentioned, at Cholechel. This is a very important station on account of being a pass for horses ; and it was, in consequence, for some time the head-quarters of a division of the army. When the troops first arrived there they found a tribe of Indians, of whom they killed twenty or thirty. The cacique escaped in a manner which astonished every one. The chief Indians always have one or two picked horses, which they keep ready for any urgent occasion. On one of these, an old white horse, the cacique sprung, taking with him his little son. The horse had neither saddle nor bridle. To avoid the shots, the Indian rode in the peculiar method of his nation ; namely, with an arm round the horse's neck, and one leg only on its back. Thus hanging on one side, he was seen patting the horse's head, and talking to him. The pursuers urged every effort in the chase ; the Commandant three times changed his horse, but all in vain. The old Indian father and his son escaped, and were free. "What a fine picture one can form in one's mind,— the naked, bronze-like figure of the old man with his little boy, riding like a Mazeppa on the white horse, thus leaving far behind him the host of his pursuers ! I saw one day a soldier striking fire with a piece of flint, which I immediately recognised as having been a part of the head of an arrow. He told me it was found near the island of Cholechel, and that they are frequently picked up there. It was between two and three inches long, and therefore twice as large as those now used in Tierra del Fuego : it was made of opaque cream-coloured flint, but the point and barbs had been intentionally broken off. It is well known that no Pampas Indians now use bows and arrows. I believe a small tribe in Banda Oriental must be excepted ; but they are * Purchas's Collection of Voyages. I believe the date was really 1537. 1833.] ANTIQUAEIAN RELIC. widely separated from the Pampas Indians, and border close on those tribes that inhabit the forest, and live on foot. It appears, therefore, that these arrow-heads are antiquarian * relics of the Indians, before the great change in habits consequent on the intro- duction of the horse into South America. * Azara lias even doubted whether the Pampas Indians ever used bows. 100 BAHIA BLANCA.

BAHIA BLANCA TO BUEXOS AYRES. September 8th.— I hired a Gaucho to accompany me on my ride to Buenos Ayres, though with some difficulty, as the father of one man was afraid to let him go, and another, who seemed willing, was described to me as so fearful, that I was afraid to take him, for I was told that even if he saw an ostrich at a distance, he would mistake it for an Indian, and would fly like the wind away. The distance to Buenos Ayres is about four hundred miles, and nearly the whole way through an uninhabited country. We started early in the morning ; ascending a few hundred feet from the basin of green turf on which Bahia Blanca stands, we entered on a wide desolate plain. It consists of a crumbling argillaceo-calcareous rock, which, from the dry nature of the climate, supports only scattered tufts of withered grass, without a single bush or tree to break the monotonous uniformity. The weather was fine, but the atmosphere remarkably hazy ; I thought the appearance foreboded a gale, but the Gauchos said it was owing to the plain, at some gr.eat distance in the interior, being on fire. After a long gallop, having changed horses twice, we reached the Eio Sauce : it is a deep, rapid, little stream, not above twenty-five feet wide. The second posta on the road to Buenos Ayres stands on its banks ; a little above there is a ford for horses, where the water does not reach to the horses' belly ; but from that point, in its course to the 1833.] SIEKKA VENTANA. 101 sea, it is quite impasscible, and hence makes a most useful barrier against the Indians. Insignificant as this stream is, the Jesuit Falconer, whose information is generally so very correct, figures it as a consider- able river, rising at the foot of the Cordillera. With respect to its source, I do not doubt that this is the case ; for the Gauchos assured me, that in the middle of the dry summer, this stream, at the same time with the Colorado, has periodical floods ; which can only originate in the snow melting on the Andes. It is ex- tremely improbable that a stream so small as the Sauce then was, should traverse the entire width of the continent ; and indeed, if it were the residue of a large river, its waters, as in other ascertained cases, would be saline. During the winter we must look to the springs round the Sierra Ventana as the source of its pure and limpid stream. I suspect the plains of Patagonia, like those of Australia, are traversed by many water-courses, which only perform their proper parts at certain periods. Probably this is the case with the water which flows into the head of Port Desire, and likewise with the Rio Chupat, on the banks of which masses of highly cellular scoriae were found by the officers employed in the survey. As it was early in the afternoon when we arrived, we took fresh horses, and a soldier for a guide, and started for the Sierra de la Ventana. This mountain is visible from the anchorage at Bahia Blanca ; and Capt. Fitz Eoy calculates its height to be 3340 feet — an altitude very remarkable on this eastern side of the continent. I am not aware that any foreigner, previous to my visit, had as- cended this mountain ; and indeed very few of the soldiers at Bahia Blanca knew anything about it. Hence we heard of beds of coal, of gold and silver, of caves, and of forests, all of which inflamed my curiosity, only to disappoint it. The distance from the posta was about six leagues, over a level plain of the same character as before. The ride was, however, interesting, as the mountain began to show its true form. When we reached the foot of the main ridge, we had much difficulty in finding any water, and we thought we should have been obliged to have passed the night without any. At last we discovered some by looking close to the mountain, for at the distance even of a few hundred yards, the streamlets were buried and entirely lost in the friable calcareous stone and loose detritus. I do not think Nature ever made a 102 BAHIA BLANCA TO BUENOS AYEES. [CHAP. vi. more solitary, desolate pile of rock ;— it well deserves its name of Hurtado, or separated. The mountain is steep, extremely rugged, and broken, and so entirely destitute of trees, and even bushes, that we actually could not make a skewer to stretch out our meat over the fire of thistle-stalks.* The strange aspect of this mountain is contrasted by the sea-like plain, which not only abuts against its steep sides, but likewise separates the parallel ranges. The uniformity of the colouring gives an extreme quietness to the vjew ; — the whitish grey of the quartz rock, and the light brown of the withered grass of the plain, being unrelieved by any brighter tint. From custom, one expects to see in the neighbourhood of a lofty and bold mountain, a broken country strewed over with huge fragments. Here nature shows that the last movement before the bed of the sea is changed into dry land may sometimes be one of tranquillity. Under these circumstances I was curious to observe how far from the parent rock any pebbles could bo found. On the shores of Bahia Blanca, and near the settlement, there were some of quartz, which certainly must have come from this source : the distance is forty-five miles. The dew, which in the early part of the night wetted the saddle- cloths under which we slept, was in the morning frozen. The plain, though appearing horizontal, had insensibly sloped up to a height of between 800 and 900 feet above the sea. In the morning (9th of September) the guide told me to ascend the nearest ridge, which he thought would lead me to the four peaks that crown the summit. The climbing up such rough rocks was very fatiguing ; the sides were so indented, that what was gained in one five minutes was often lost in the next. At last, when I reached the ridge, my disappointment was extreme in finding a precipitous valley as deep as the plain, which cut the chain transversely in two, and separated me from the four points. This valley is very narrow, but flat-bottomed, and it forms a fine horse-pass for the Indians, as it connects the plains on the northern and southern sides of the range. Having descended, and while crossing it, I saw two horses grazing : I immediately hid myself in the long grass, and began to reconnoitre ; but as I could see no signs of Indians I proceeded cautiously on my second ascent. It was late in the day, and this part of the mountain, like the other, was steep and rugged. * I call these thistle-stalks for the vmnt of a more correct name. I believe it is a species of Eryngium. 1833.] SIERRA VENTANA. 103 I was on the top of the second peak by two o'clock, but got there with extreme difficulty ; every twenty yards I had the cramp in the upper part of both thighs, so that I was afraid I should not have been able to have got down again. It was also necessary to return by another road, as it was out of the question to pass over the saddle-back. I was therefore obliged to give up the two higher peaks. Their altitude was but little greater, and every purpose of geology had been answered ; so that the attempt was not worth the hazard of any further exertion. I presume the cause of the cramp was the great change in the kind of muscular action, from that of hard riding to that of still harder climbiug. It is a lesson worth remembering, as in some cases it might cause much difficulty. I have already said the mountain is composed of white quartz rock, and with it a little glossy clay-slate is associated. At the height of a few hundred feet above the plain, patches of conglo- merate adhered in several places to the solid rock. They re- sembled in hardness, and in the nature of the cement, the masses which may be seen daily forming on some coasts. I do not doubt these pebbles were in a similar manner aggregated, at a period when the great calcareous formation was depositing beneath tbe surrounding sea. We may believe that the jagged and battered forms of the hard quartz yet show the effects of the waves of an open ocean. I was, on the whole, disappointed with this ascent. Even the view was insignificant ; — a plain like the sea, but without its beau- tiful colour and defined outline. The scene, however, was novel, and a little danger, like salt to meat, gave it a relish. That the danger was very little was certain, for my two companions made a good fire — a thing which is never done when it is suspected that Indians are near. I reached the place of our bivouac by sunset, and drinking much mate, and smoking several cigaritos, soon made up my bed for the night. The wind was very strong and cold, but I never slept more comfortably. September 10th. — In the morning, having fairly scudded before the gale, we arrived by the middle of the day at the Sauce posta. On the road we saw great numbers of deer, and near the mountain a guanaco. The plain, which abuts against the Sierra, is traversed by some curious gullies, of which one was about twenty feet wide, and at least thirty deep; wo were obliged in consequence to make a considerable circuit before we could find a pass. We 104 BAHIA BLANCA TO BUENOS AYEES. [CHAP, vi stayed the night at the posta, the conversation, as was generally the case, being about the Indians. The Sierra Ventana was formerly a great place of resort ; and three or four years ago there was much fighting there. My guide had been present when many Indians were killed : the women escaped to the top of the ridge, and fought most desperately with great stones ; many thus saving themselves. September llth.— Proceeded to the third posta in company with the lieutenant who commanded it. The distance is called fifteen leagues; but it is only guess-work, and is generally overstated. The road was uninteresting, over a dry grassy plain ; and on our left hand at a greater or less distance there were some low hills ; a continuation of which we crossed close to the posta. Before our arrival we met a large herd of cattle and horses, giiarded by fifteen soldiers ; but we were told many had been lost. It is very diffi- cult to drive animals across the plains ; for if in the night a puma, or even a fox, approaches, nothing can prevent the horses dispers- ing in every direction ; and a storm will have the same effect. A short time since, an officer left Buenos Ayres with five hundred horses, and when he arrived at the army he had under twenty. Soon afterwards we perceived by the cloud of dust, that a party of horsemen were coming towards us ; when far distant my com- panions knew them to be Indians, by their long hair streaming behind their backs. The Indians generally have a fillet round their heads, but never any covering ; and their black hair blowing across their swarthy faces, heightens to an uncommon degree the wildness of their appearance. They turned out to be a party of Bernantio's friendly tribe, going to a salina for salt. The Indians eat much salt, their children sucking it like sugar. This habit is very different from that of the Spanish Gauchos, who, leading the same kind of life, eat scarcely any ; according to Mungo Park,* it is people who live on vegetable food who have an unconquerable desire for salt. The Indians gave us good-humoured nods as they passed at full gallop, driving before them a troop of horses, and followed by a train of lanky dogs. September \1tli and 13th. — I staid at this posta two days, waiting for a troop of soldiers, which General Kosas had the kindness to send to inform me, would shortly travel to Buenos Ayres ; and he advised me to take the opportunity of the escort. In the morning * Travels in Africa, p. 233. 1833.] THKOWING THE BOLAS. 105 we rode to some neighbouring hills to view the country, and to examine the geology. After dinner the soldiers divided themselves into two parties for a trial of skill with the bolas. Two spears were stuck in the ground thirty-five yards apart, but they were struck and entangled only once in four or five times. The balls can be thrown fifty or sixty yards, but with little certainty. This, however, does not apply to a man on horseback; for when the speed of the horse is added to the force of the arm, it is said, that they can be whirled with effect to the distance of eighty yards. As a proof of their force, I may mention, that at the Falkland Islands, when the Spaniards murdered some of their own countrymen and all the Englishmen, a young friendly Spaniard was running away, when a great tall man, by name Luciano, came at full gallop after him, shouting to him to stop, and saying that he only wanted to speak to him. Just as the Spaniard was on the point of reaching the boat, Luciano threw the balls : they struck him on the legs with such a jerk, as to throw him down and to render him for some time insensible. The man, after Luciano had had his talk, was allowed to escape. He told us that his legs were marked by great weals, where the thong had wound round, as if he had been flogged with a whip. In the middle of the day two men arrived, who brought a parcel from the next posta to be forwarded to the general: so that besides these two, our party consisted this evening of my guide and self, the lieutenant, and his four soldiers. The latter were strange beings ; the first a fine young negro ; the second half Indian and negro ; and the two others nondescripts ; namely, an old Chilian miner, the colour of mahogany, and another partly a mulatto ; but two such mongrels, with such detestable expres- sions, I never saw before. At night, when they were sitting round the fire, and playing at cards, I retired to view such a Salvator Ilosa scene. They were seated under a low cliff, so that I could look down upon them ; around the party were lying dogs, arms, remnants of deer and ostriches ; and their long spears were stuck in the turf. Further in the dark background, their horses were tied up, ready for any sudden danger. If the stillness of the desolate plain was broken by one of the dogs barking, a soldier, leaving the fire, would place his head close to the ground, and thus slowly scan the horizon. Even if the noisy teru-tero uttered its scream, there would be a pause in the conversation, and every head, for a moment, a little inclined. 106 BAHIA BLANCA TO BUENOS AYRES. [CHAP. vi. What a life of misery these men appear to us to lead ! They were at least ten leagues from the Sauce posta, and since the murder committed by the Indians, twenty from another. The Indians are supposed to have made their attack in the middle of the night ; for very early in the morning after the murder, they were luckily seen approaching this posta. The whole party here, however, escaped, together with the troop of horses; each one taking a line for himself, and driving with him as many animals as he was able to manage. The little hovel, built of thistle-stalks, in which they slept, neither kept out the wind nor rain ; indeed in the latter case the only effect the roof had, was to condense it into larger drops. They had nothing to eat excepting what they could catch, such as ostriches, deer, armadilloes, etc., and their only fuel was the dry stalks of a small plant, somewhat resembling an aloe. The sole luxury which these men enjoyed was smoking the little paper cigars, and sucking mate. I used to think that the carrion vultures, man's constant attendants on these dreary plains, while seated on the little neighbouring cliffs seemed by their very patience to say, " Ah ! when the Indians come we shall have a feast." In the morning we all sallied forth to hunt, and although we had not much success, there were some animated chases. Soon after starting the party separated, and so arranged their plans, that at a certain time of the day (in guessing which they show much skill) they should all meet from different points of the compass on a plain piece of ground, and thus drive together the wild animals. One day I went out hunting at Bahia Blanca, but the men there merelj rode in a crescent, each being about a quarter of a mile apart froi the other. A fine male ostrich being turned by the headmost riders, tried to escape on one side. The Gauchos pursued at reckless pace, twisting their horses about with the most admirable command, and each man whirling the balls round his head. At length the foremost threw them, revolving through the air : in an instant the ostrich rolled over and over, its legs fairly lashed together by the thong. The plains abound with three kinds of partridge,* two of which are as large as hen pheasants. Their destroyer, a small and pretty fox, was also singularly numerous ; in the course of the day we * Two species of Tiuamus, and Eudromia elegans of A. d'Orbigny which can only be called a partridge with regard to its habits. 1833.] HOSPITALITY. 107 could not have seen less than forty or fifty. They were generally near their earths, but the dogs killed one. When we returned to the posta, we found two of the party returned who had been hunt- ing by themselves. They had killed a puma, and had found an ostrich's nest with twenty-seven eggs in it. Each of these is said to equal in weight eleven hen's eggs ; so that we obtained from this one nest as much food as 297 hen's eggs would have given. September 14 BANDA ORIENTAL. [CHAP. Vin. de las Cuentas : a hill distant many miles to the northward. The name signifies hill of beads. I was assured that vast numbers of little round stones, of various colours, each with a small cylindrical hole, are found there. Formerly the Indians used to collect them, for the purpose of making necklaces and bracelets — a taste, I may observe, which is common to all savage nations, as well as to the most polished. I did not know what to understand from this story, but upon mentioning it at the Cape of Good Hope to Dr. Andrew Smith, he told me that he recollected finding on the south-eastern coast of Africa, about one hundred miles to the eastward of St. John's river, some quartz crystals with their edges blunted from attrition, and mixed with gravel on the sea-beach. Each crystal was about five lines in diameter, and from an inch to an inch and a half in length. Many of them had a small canal extending from one extremity to the other, perfectly cylindrical, and of a size that readily admitted a coarse thread or a piece of fine catgut. Their colour was red or dull white. The natives were acquainted with this structure in crystals. I have mentioned these circumstances because, although no crystallized body is at present known to assume this form, it may lead some future traveller to investigate the real nature of such stones. While staying at this estancia, I was amused with what I saw and heard of the shepherd-dogs of the country.* When riding, it is a common thing to meet a large ^flock of sheep guarded by one or two dogs, at the distance of some miles from any house or man. I often wondered how so firm a friendship had been established. The method of education consists in separating the puppy, while very young, from the bitch, and in accustoming it to its future com- panions. An ewe is held three or four times a day for the little thing to suck, and a nest of wool is made for it in the sheep-pen ; at no time is it allowed to associate with other dogs, or with the children of the family. The puppy is, moreover, generally cas- trated ; so that, when grown up, it can scarcely have any feelings in common with the rest of its kind. From this education it has no wish to leave the flock, and just as another dog will defend its master, man, so will these the sheep. It is amusing to observe, when approaching a flock, how the dog immediately advances * M. A. d'Orbigny has given nearly a similar account of these do. is. wards we came to a spot where, from the fresh footsteps of men, children, and horses, it was evident that the party had crossed the river. April Z2nd. — The country remained the same, and was extremely uninteresting. The complete similarity of the productions through- out Patagonia is one of its most striking characters. The level plains of arid shingle support the same stunted and dwarf plants ; and in the valleys the same thorn-bearing bushes grow. Every- where we see the same birds and insects. Even the very banks of the river and of the clear streamlets which entered it, were scarcely enlivened by a brighter tint of green. The curse of sterility is on the land, and the water flowing over a bed of pebbles partakes of the same curse. Hence the number of waterfowl is very scanty ; for there is nothing to support life in the stream of this barren river. Patagonia, poor as she is in some respects, can however boast of a greater stock of small rodents * than perhaps any other country in the world. Several species of mice are externally characterized by large thin ears and a very fine fur. These little animals swarm amongst the thickets in the valleys, where they cannot for months together taste a drop of water excepting the dew. They all seem to be cannibals ; for no sooner was a mouse caught in one of my traps than it was devoured by others. A small and delicately shaped fox, which is likewise very abundant, probably derives its entire support from these small animals. The guanaco is also in his proper district ; herds of fifty or a hundred were common ; and, as I have stated, we saw one which must have contained at least five hundred. The puma, with the condor and other carrion- hawks in its train, follows and preys upon these animals. The footsteps of the puma were to be seen almost everywhere on the banks of the rivers ; and the remains of several guanacos, with their necks disclocated and bones broken, showed how they had their death. April 24^. — Like the navigators of old when approaching an unknown land, we examined and watched for the most trivial sign of a change.

The top, however, of a heavy bank of clouds, which remained almost constantly in ono position, was the most promising sign, and eventually turned out a true harbinger. At first the clouds were mistaken for the mountains themselves,, instead of the masses of vapour condensed by their icy summits. April 26£/i. — We this day met with a marked change in the geological structure of the plains. From the first starting I had carefully examined the gravel in the river, and for the two last days had noticed the presence of a few small pebbles of a very cellular basalt. These gradually increased in number and in size, but none were as large as a man's head. This morning, however, pebbles of the same rock, but more compact, suddenly became abundant, and in the course of half an hour Ave saw, at the distance of five or six miles, the angular edge of a great basaltic platform. When we arrived at its base we found the stream bubbling among the fallen blocks. For the next twenty-eight miles the river-course was encumbered with these basaltic masses. Above that limit immense fragments of primitive rocks, derived from the surrounding boulder-formation, were equally numerous. None of the fragments of any considerable size had been washed more than three or four miles down the river below their parent- source : considering the singular rapidity of the great body of water in the Santa Cruz, and that no still reaches occur in any part, this example is a most striking one, of the inefficiency of rivers in transporting even moderately-sized fragments. The basalt is only lava, which has flowed beneath the sea ; but the eruptions must have been on the grandest scale. At the point where we first met this formation it was 120 feet in thick- ness ; following up the river course, the surface imperceptibly rose and the mass became thicker, so that at forty miles above the first station it was 320 feet thick. What the thickness may be close to the Cordillera, I have no means of knowing, but the platform there attains a height of about three thousand feet above the level of the sea : we must therefore look to the mountains of that great chain for its source ; and worthy of such a source are streams that have flowed over the gently inclined bed of the sea to a distance of one hundred miles. At the first glance of the basaltic cliffs on the opposite sides of the valley, it was evident that the strata once were 172 S. CRUZ, PATAGONIA. [CHAP. ix. united. What power, then, has removed along a whole line of country, a solid mass of very hard rock, which had an average thickness of nearly three hundred feet, and a breadth varying from rather less than two miles to four miles ? The river, though it has so little power in transporting even inconsiderable fragments, yet in the lapse of ages might produce by its gradual erosion an effect, of which it is difficult to judge the amount. But in this case, independently of the insignificance of such an agency, good reasons can be assigned for believing that this valley was formerly occupied by an arm of the sea. It is needless in this work to detail the arguments leading to this conclusion, derived from the form and the nature of the step-formed terraces on both sides of the valley, from the manner in which the bottom of the valley near the Andes expands into a great estuary-like plain with sand-hil- locks on it, and from the occurrence of a few sea-shells lying iu the bed of the river. If I had space I could prove that South America was formerly here cut off by a strait, joining the Atlantic and Pacific oceans, like that of Magellan. But it may yet bo asked, how has the solid basalt been moved ? Geologists formerly would have brought into play, the violent action of some over- whelming debacle ; but in this case such a supposition would have been quite inadmissible ; because, the same step-like plains with existing sea-shells lying on their surface, which front the long line of the Patagonian coast, sweep up on each side of the valley of Santa Cruz. No possible action of any flood could thus have modelled the land, either within the valley or along the open coast ; and by the formation of such step-like plains or terraces the valley itself had been hollowed out. Although we know that there are tides, which run within the Narrows of the Strait of Magellan at the rate of eight knots an hour, yet we must confess that it makes the head almost giddy to reflect on the number of years, century after century, which the tides, unaided by a heavy surf, must have required to have corroded so vast an area anc thickness of solid basaltic lava. Nevertheless, we must believe that the strata undermined by the waters of this ancient strait, were broken up into huge fragments, and these lying scattered on the beach, were reduced first to smaller blocks, then to pebbles and lastly to the most impalpable mud, which the tides drifted far into the Eastern or Western Ocean. With .the change in the geological structure of the plains the 1834] THE CONDOR. 173 character of the landscape likewise altered. While rambling up some of the narrow and rocky defiles, I conld almost have fancied myself transported back again to the barren valleys of the island of St. Jago. Among the basaltic cliffs, I found some plants which I had seen nowhere else, but others I recognised as being wanderers from Tierra del Fuego. These porous rocks serve as a reservoir for the scanty rain-water ; and consequently on the line where the igneous and sedimentary formations unite, some small springs (most rare occurrences in Patagonia) burst forth ; and they could be distinguished at a distance by the circumscribed patches of bright green herbage. April 27th. — The bed of the river became rather narrower, and hence the stream more rapid. It here ran at the rate of six knots an hour. From this cause, and from the many great angular fragments, tracking the boats became both dangerous and laborious. This day I shot a condor. It measured from tip to tip of the wings, eight and a half feet, and from beak to tail, four feet. This bird is known to have a wide geographical range, being found on the west coast of South America, from the Strait of Magellan along the Cordillera as far as eight degrees north of the equator. The steep cliff near the mouth of the Eio Negro is its northern limit on the Patagonian coast ; and they have there wandered about four hundred miles from the great central line of their habitation in the Andes. Further south, among the bold precipices at the head of Port Desire, the conder is not uncommon ; yet only a few stragglers occasionally visit the sea-coast. A line of cliff near the month of the Santa Cruz is frequented by these birds, and about eighty miles up the river, where the sides of the valley are formed by steep basaltic precipices, the condor reappears. From these facts, it seems that the condors require perpendicular cliffs. In Chile, they haunt, during the greater part of the year, the lower country near the shores of the Pacific, and at night several roost together in one tree; but in the early part of summer, they retire to the most inaccessible parts of the inner Cordillera, there to breed in peace. With respect to their propagation, I was told by the country people in Chile, that the condor makes no sort of nest, but in the months of November and December lays two large white eggs on a 174 S- ORUX, PATAGONIA. [CHAP. ix. shelf of bare rock. It is said that the young condors cannot fly for an entire year; and long after they are able, they continue to roost by night, and hunt by day with their parents. The old birds generally live in pairs ; but among the inland basaltic cliffs of the Santa Cruz, I found a spot, where scores must usually haunt. On coming suddenly to the brow of the precipice, it was a grand spectacle to see between twenty and thirty of these great birds start heavily from their resting-place, and wheel away in majestic circles. From the quantity of dung on the rocks, they must long have frequented this cliff for roosting and breeding. Having gorged themselves with carrion on the plains below, they retire to these favourite ledges to digest their food. From these facts, the condor, like the gallinazo, must to a certain degree be considered as a gre- garious bird. In this part of the country they live altogether on the guanacos which have died a natural death, or, as more com- monly happens, have been killed by the pumas. I believe, from what I saw in Patagonia, that they do not on ordinary occasions extend their daily excursions to any great distance from their regular sleeping-places. The condors may oftentimes be seen at a great height, soaring- over a certain spot in the most graceful circles. On some occasions I am sure that they do this only for pleasure, but on others, the Chileno countryman tells you that they are watching a dying animal, or the puma devouring its prey. If the condors glide down, and then suddenly all rise together, the Chileno knows that it is the puma which, watching the carcass, has sprung out to drive away the robbers. Besides feeding on carrion, the condors fre- quently attack young goats and lambs ; and the shepherd-dogs are trained, whenever they pass over, to run out, and looking upwards to bark violently. The Chilenos destroy and catch numbers. Two methods are used ; one is to place a carcass 'on a level piece of ground within an enclosure of sticks with an opening, and when the condors are gorged, to gallop up on horseback to the entrance, and thus enclose them : for when this bird has not space to run, it cannot give its body sufficient momentum to rise from the ground. The second method is to mark the trees in which, frequently to the number of five or six together, they roost, and then at night to climb up and noose them. They are such heavy sleepers, as I have myself witnessed, that this is not a difficult task. At Valparaiso, I have seen a living condor sold for sixpence, but the common price 1834.] THE CONDOR. 175 is eight or ten shillings. One which I saw brought in, had been tied with rope, and was much injured ; yet, the moment the lino was cut by which its bill was secured, although surrounded by people, it began ravenously to tear a piece of carrion. In a garden at the same place, between twenty and thirty were kept alive. They were fed only once a week, but they appeared in pretty good health.* The Chileno countrymen assert that the condor will live, and retain its vigour, between five and six weeks without eating : I cannot answer for the truth of this, but it is a cruel experiment, which very likely has been tried. When an animal is killed in the country, it is well known that the condors, like other carrion-vultures, soon gain intelligence of it, and congregate in an inexplicable manner. In most cases it must not be overlooked, that the birds have discovered their prey, and have picked the skeleton clean, before the flesh is in the least degree tainted. Eemembering the experiments of M. Audubon, on the little smelling powers of carrion-hawks, I tried in the above- mentioned garden the following experiment : the condors were tied, each by a rope, in a long row at the bottom of a wall ; and having folded up a piece of meat in white paper, I walked backwards and forwards, carrying it in my hand at the distance of about three yards from them, but no notice whatever was taken. I then threw it on the ground, within one yard of an old male bird ; he looked at it for a moment with attention, but then regarded it no more. With a stick I pushed it closer and closer, until at last he touched it with his beak ; the paper was then instantly torn off with fury, and at the same moment, every bird in the long row began struggling and flapping its wings. Under the same circumstances, it would have been quite impossible to have deceived a dog. The evidence in favour of and against the acute smelling powers of carrion-vultures is singularly balanced. Professor Owen has demonstrated that the olfactory nerves of the turkey-buzzard (Cathartes aura) are highly developed ; and on the evening when Mr. Owen's paper was read at the Zoological Society, it was men- tioned by a gentleman that he had seen the carrion-hawks in the West Indies on two occasions collect on the roof of a house, when a corpse had become offensive from not having been buried ; in * I noticed that several hours before any one of the condors died, all the lice, with which it was infested, crawled to the outside feathers. I was assured that this always happened. 17(3 S. CRUZ, PATAGONIA. [CHAP. ix. this case, the intelligence could hardly have been acquired by sight. On the other hand, besides the experiments of Audobon and that one by myself, Mr. Bachman has tried in the United States many varied plans, showing that neither the turkey-buzzard (the species dissected by Professor Owen) nor the gallinazo find their food by smell. He covered portions of highly offensive offal with a thin canvas cloth, and strewed pieces of meat on it : these the carrion-vultures ate up, and then remained quietly standing, with their beaks within the eighth of an inch of the putrid mass, without discovering it. A small rent was made in the canvas, and the offal was immediately discovered; the canvas was replaced by a fresh piece, and meat again put on it, and was again devoured by the vultures without their discovering the hidden mass on which they were trampling. These facts are attested by the signatures of six gentlemen, besides that of Mr. Bachman.* Often when lying down to rest on the open plains, on looking upwards, I have seen carrion-hawks sailing through the air at a great height. Where the country is level I do not believe a space of the heavens, of more than fifteen degrees above the horizon, is commonly viewed with any attention by a person either walking or on horseback. If such be the case, and the vulture is on the wing at a height of between three and four thousand feet, before it could come within the range of vision, its distance in a straight line from the beholder's eye, would be rather more than two British miles. Might it not thus readily be overlooked? When an animal is killed by the sportsman in a lonely valley, may he not all the while be watched from above by the sharp-sighted bird ? And will not the manner of its descent proclaim throughout the district to the whole family of carrion-feeders, that their prey is at hand ? When the condors are wheeling in a flock round and round any spot, their flight is beautiful. Except when rising from the ground, I do not recollect ever having seen one of these birds flap its wings. Near Lima, I watched several for nearly half an hour, without once taking off my eyes : they moved in large curves, sweeping in circles, descending and ascending without giving a single flap. As they glided close over my head, I intently watched from an oblique position, the outlines of the separate and great terminal feathers of each wing ; and these separate feathers, if there had been the least vibratory movement, would have appeared as if blended together ; * London's Magazine of Xat. Hist., vol. vii. 1834.] CORDILLERA. 1 77 but they were scon distinct against the blue sky. The head and neck were moved frequently, and apparently with force ; and the extended wings seemed to form the fulcrum on which the move- ments of the neck, body, and tail acted. If the bird wished to descend, the wings were for a moment collapsed; and when again expanded with an altered inclination, the momentum gained by the rapid descent seemed to urge the bird upwards with the even and steady movement of a paper kite. In the case of any bird soaring, its motion must be sufficiently rapid, so that the action of the inclined surface of its body on the atmosphere may counterbalance its gravity. The force to keep up the momentum of a body moving in a horizontal plane in the air (in which there is so little friction) cannot be great, and this force is all that is wanted. The move- ment of the neck and body of the condor, we must suppose, is sufficient for this. However this may be, it is truly wonderful and beautiful to see so great a bird, hour after hour, without any apparent exertion, wheeling and gliding over mountain and river. J.ju-il 29^.— From some high laud we hailed with joy the white summits of the Cordillera, as they wore seen occasionally peeping through their dusky envelope of clouds. During the few suc- ceeding days we continued to get on slowly, for we found the river- course very tortuous, and strewed with immense fragments of various ancient slaty rocks, and of granite. The plain bordering the valley had here attained an elevation of about 1100 feet above the river, and its character was much altered. The well-rounded pebbles of porphyry were mingled with many immense angular fragments of basalt and of primary rocks. The first of these erratic boulders which I noticed, was sixty-seven miles distant from the nearest mountain ; another which I measured was five yards square, and projected five feet above the gravel. Its edges were so angular, and its size so great, that I at first mistook it for a rock in situ, and took out my compass to observe the direction of its cleavage. The plain here was not quite so level as that nearer the coast, but yet it betrayed no signs of any great violence. Under these cir- cumstances it is, I believe, quite impossible to explain the transportal of these gigantic masses of rock so many miles from their parent- source, on any theory except by that of floating icebergs. During the two last days we met with signs of horses, and with several small articles which had belonged to the Indians^such as 178 S. CRUZ, PATAGONIA. [CHAP, ix parts of a mantle and a bunch of ostrich feathers— but they ap- peared to have been lying long on the ground. Between the place where the Indians had so lately crossed the river and this neigh- bourhood, though so many miles apart, the country appears to be quite unfrequented. At first, considering the abundance of the guanacos, I was surprised at this; but it is explained by the stony nature of the plains, which would soon disable an unshod horse from taking part in the chase. Nevertheless, in two places in this very central region, I found small heaps of stones, which I do not think could have been accidentally thrown together. They were placed on points, projecting over the edge of the highest lava cliff, and they resembled, but on a small scale, those near Port Desire. Miy 4:th. — Captain Fitz Eoy determined to take the boats no higher. The river had a winding course, and was very rapid ; and the appearance of the country offered no temptation to proceed any further. Everywhere we met with the same productions, and the same dreary landscape. We were now one hundred and forty miles distant from the Atlantic, and about sixty from the nearest arm of the Pacific. The valley in this upper part expanded into a Avide basin, bounded on the north and south by the basaltic plat- forms, and fronted by the long range of the snow-clad Cordillera. But we viewed these grand mountains with regret, for we were obliged to imagine their nature and'productions, instead of stand- ing, as we had hoped, on their summits. Besides the useless loss of time which an attempt to ascend the river any higher would have cost us, we had already been for some days on half allowance of bread. This, although really enough for reasonable men, was, after a hard day's march, rather scanty food : a light stomach and an easy digestion are good things to talk about, but very unpleasant in practice. 5th. — Before sunrise we commenced our descent. We shot down the stream with great rapidity, generally at the rate of ten knots an hour. In this one day we effected what had cost us five-and-a- half hard days' labour in ascending. On the 8tb, we reached the Beagle after our twenty-one days' expedition. Every one, excepting myself, had cause to be dissatisfied ; but to me the ascent afforded a most interesting section of the great tertiary formation of Patagonia. On March 1st, 1833, and again on March I6>h, 1834, the Beagle 1834.] FALKLAND ISLANDS. 170 anchored in Berkeley Sound, in East Falkland Island. This archi- pelago is situated in nearly the same latitude with the mouth of the Strait of Magellan; it covers a space of one hundred and twenty by sixty geographical miles, and is a little more than half the size of Ireland. After the possession of these miserable islands had been contested by France, Spain, and England, they were left uninhabited. The government of Buenos Ayres then sold them to a private individual, but likewise used them, as old Spain had done before, for a penal settlement. England claimed her right and seized them. The Englishman who was left in charge of the flag was consequently murdered. A British officer was next sent, un- supported by any power : and when we arrived, we found him in charge of a population, of which rather more than half were runaway rebels and murderers. The theatre is worthy of the scenes acted on it. An undulating- laud, with a desolate and wretched aspect, is everywhere covered by a peaty soil and wiry grass, of one monotonous brown colour. Here and there a peak or ridge of grey quartz rock breaks through the smooth surface. Every one has heard of the climate of these regions ; it may be compared to that which is experienced at the height of between one and two thousand feet, on the mountains of North Wales ; having however less sunshine and less frost, but more wind and rain.* IQth. — I will now describe a short excursion which I made round a part of this island. In the morning I started with six horses and two Gauchos : the latter were capital men for the purpose, and well accustomed to living on their own resources. The weather was very boisterous and cold, with heavy hail-stornis. We got on, however, pretty well, but, except the geology, nothing could be less interesting than our day's ride. The country is uniformly the same undulating moorland; the surface being covered by light brown withered grass and a few very small shrubs, all springing out of an elastic peaty soil. In the valleys here and there might l>e seen a small flock of wild geese, and everywhere the ground was * From accounts published since our voyage, and more especially from several interesting letters from Capt. Sulivan, K.N., employed on the survey, it appears that we took an exaggerated view of the badness of the climate of these islands. But when I reflect on the almost universal covering of peat, and on the fact of wheat seldom ripening here, I can hardly believe that the climate in summer is so fine and dry as it has lately been represented. ISO FALKLAND ISLANDS. [CHAP, ix- go soft that the snipe were ablo to feed. Besides these two birds there were few others. There is one main range of hills, nearly two thousand feet in height, and composed of quartz rock, the rugged and barren crests of which gave us some trouble to cross. On the south side we came to the best country for wild cattle ; we met, however, no great number, for they had been lately much harassed. In the evening we came across a small herd. One of my com- panions, St. Jago by name, soon separated a fat cow ; he threw the bolas, and it struck her legs, but failed in becoming entangled. Then dropping his hat to mark the spot where the balls were left, Avhile at full gallop, he uncoiled his lazo, and after a most severe chase, again came up to the cow, and caught her round the horns. The other Gaucho had gone on ahead with the spare horses, so that St. Jago had some difficulty in killing the furious beast. He managed to get her on a level piece of ground, by taking advantage of her as often as she rushed at him; and when she would not move, my horse, from having been trained, would canter up, and •with his chest give her a violent push. But when on level ground it does not appear an easy job for one man to kill a beast mad with terror. Nor would it be so, if the horse, when left to itself without its rider, did not soon learn, for its own safety, to keep the lazo tight ; so that, if the cow or ox moves forward, the horse moves just as quickly forward ; otherwise, it stands motionless leaning on one side. This horse, however,*Vas a young one, and would not stand still, but gave in to the cow as she struggled. It was admir- able to see with what dexterity St. Jago dodged behind the beast, till at last he contrived to give the fatal touch to the main tendon of the hind leg ; after which, without much difficulty, he drove his knife into the head of the spinal marrow, and the cow dropped as if struck by lightning. He cut off pieces of flesh with the skin to it, but without any bones, sufficient for our expedition. We then rode on to our sleeping-place, and had for supper ' carne con cuero,' or meat roasted with the skin on it. This is as superior to common beef as venison is to mutton. A large circular piece taken from the back is roasted on the embers with the hide downwards and in the form of a saucer, so that none of the gravy is lost. If any worthy alderman had sapped with us that evening, ' carne con cuero/ without doubt, would soon "have been celebrated in London. During the night it rained, and the next day (17th) was very . HAI. TX.] WILD HORSES. 181 stormy, with much hail and snow. AVo rode across the island to the neck of land which joins the Eincon del Toro (the great peninsula at the S.W. extremity) to the rest of the island. From the great number of cows which have been killed, there is a large proportion of bulls. These wander about single, or two and three together, and are very savage. I never saw such magnificent boasts; they equalled in the size of their huge heads and necks the Grecian marble sculptures. Capt. Sulivan informs me that the hide of an average-sized bull weighs forty-seven pounds, whereas a hide of this weight, less thoroughly dried, is considered as a very heavy one at Monte Video. The young bulls generally run away for a short distance ; but the old ones do not stir a step, except to rush at man and horse ; and many horses have been thus killed. An old bull crossed a boggy stream, and took his stand on the opposite side to us ; we in vain tried to drive him away, and fail- ing, were obliged to make a large circuit. The Gauchos in revengo determined to emasculate him and render him for the future harm- less. It was very interesting to see how art completely mastered force. One lazo was thrown over his horns as he rushed at tho horse, and another round his hind legs : in a minute the monster was stretched powerless on the g found. After the lazo has once been drawn tightly round the horns of a furious animal, it does not at first appear an easy thing to disengage it again without killing the beast ; nor, I apprehend, would it be so if the man was by him- self. By the aid, however, of a second person throwing his lazo so as to catch both hind legs, it is quickly managed : for the animal, as long as its hind legs are kept outstretched, is quite helpless, and the first man can with his hands loosen his lazo from the horns, and then quietly mount his horse; but the moment the second man, by backing ever so little, relaxes the strain, the lazo slips off the legs of the struggling beast, which then rises free, shakes himself, and vainly rushes at his antagonist. During our whole ride we saw only one troop of wild horses. These animals, as well as the cattle, were introduced by the French in 176i, since which time both have greatly increased. It is a curious fact, that the horses have never left the eastern end of the island, although there is no natural boundary to prevent them from roaming, and that part of the island is not more tempting than the rest. The Gauchos whom I asked, though asserting this to be the case, were unable to account for it, except from the strong FALKLAND ISLANDS. [CHAP. ix. attachment which horses have to any locality to which they are accustomed. Considering that the island does not appear fully stocked, and that there are no beasts of prey, I was particularly curious to know what has checked their originally rapid increase. That in a limited island some check would sooner or later supervene, is inevitable ; but why has the increase of the horse been checked sooner than that of the cattle ? Capt. Sulivan has taken much pains for me in this inquiry. The Gauchos employed here attribute it chiefly to the stallions constantly roaming from place to place, and compelling the rnares to accompany them, whether or not the young foals are able to follow. One Gaucho told Capt. Sulivan that he had watched a stallion for a whole hour, violently kicking and biting a mare till he forced her to leave her foal to its fate. Capt. Sulivan can so far corroborate this curious accoiint, that he has several times found young foals dead, whereas he has never found a dead calf. Moreover, the dead bodies of full-grown horses are more frequently found, as if more subject to disease or accidents, than those of the cattle. From the softness of the ground their hoofs often grow irregularly to a great length, and this causes ' lameness. The predominant colours are roan and iron-grey. All the horses bred here, both tame and wild, are rather small-sized, though generally in good condition ; and they have lost so much strength, that they are unfit to be used in taking wild cattle with the lazo : in consequence, it is necessary to go to the great expense of importing fresh horses from the Plata. At some future period the southern hemisphere probably will have its breed of Falkland ponies, as the northern has its Shetland breed. The cattle, instead of having degenerated like the horses, seem, as before remarked, to have increased in size ; and they are much more numerous than the horses. Capt. Sulivan informs me that they vary much less in the general form of their bodies and in the shape of their horns than English cattle. In colour they differ much ; and it is a remarkable circumstance, that in different parts of this one small island, different colours predominate. Bound Mount Usborne, at a height of from 1000 to 1500 feet above the sea, about half of some of the herds are mouse or lead-coloured, a tint which is not common in other parts of the island. Near Port Pleasant dark brown prevails, whereas south of Choiseul Sound (which almost divides the island into two parts), white beasts with black heads and feet are the most common : in all parts black, and . ix.] WILD RABBITS. 183 some spotted animals may be observed. Capt. Sulivan remarks, that the difference in the prevailing colours was so obvious, that in looking for the herds near Port Pleasant, they appeared from a long distance like black spots, whilst south of Choiseul Sound they appeared like white spots on the hill-sides. Capt. Sulivan thinks that the herds do not mingle ; and it is a singular fact, that the mouse-coloured cattle, though living on the high land, calve about a month earlier in the season than the other coloured beasts on the lower land. It is interesting thus to find the once domesticated cattle breaking into three colours, of which some one colour would in all probability ultimately prevail over the others, if the herds were left undisturbed for the next several centuries. The rabbit is another animal which has been introduced, and has succeeded very well ; so that they abound over large parts of the island. Yet, like the horses, they are confined within certain limits; for they have not crossed the central chain of^iills, nor would they have extended even so far as its base, if, as the Gauchos informed me, small colonies had not been carried there. I should not have supposed that these animals, natives of northern Africa, could have existed in a climate so humid as this, and which enjoys so little sunshine that even wheat ripens only occasionally. It is asserted that in Sweden, which any one would have thought a more favourable climate, the rabbit cannot live out of doors. The first few pair, moreover, had here to contend against pre-existing enemies, in the fox and some large hawks. The French naturalists have considered the black variety a distinct species, and called it Lepus Magellanicus.* They imagined that Magellan, when talking of an animal under the Hame of " conejos " in the Strait of Magellan, referred to this species ; but he was alluding to a small cavy, which to this day is tlms called by the Spaniards. The Gauchos laughed at the idea of the black kind being different from the grey, and they said that at all events it had not extended its range any further than the grey kind ; that the two were never found separate ; and that they readily bred together, and produced piebald offspring. * Lesson's Zoology of the Voyage of the Coquille, torn. i. p. 168. All the early voyagers, and especially Bougainville, distinctly state that the wolf-like fox was the only native animal on the island. The distinction of the rabbit as a species, is taken from peculiarities in the fur, from the shape of the head, and from the shortness of the cars. I may here observe that the difference between the Irish and English hare rests upon nearly similar characters, only more strongly marked. 184 FALKLAND ISLANDS. [CUAK ix. Of the latter I now possess a specimen, and it is marked about the head differently from the French specific description. This cir- cumstance shows how cautious naturalists should be in making species ; for even Cuvier, on looking at the skull of one of these rabbits, thought it was probably distinct ! The only quadruped native to the island * is a large wolf-like fox (Canis antarcticus), which is common to both East and West Falk- land. I have no doubt it is a peculiar species, and confined to this archipelago; because many sealers, Gauchos, and Indians, who have visited these islands, all maintain that no such animal is found in any part of South America. Molina, from a similarity in habits, thought that this was the same with his "culpeu;"f but I have seen both, and they ara quite distinct. These wolves are well known, from Byron's account of their tameness and curiosity, which the sailors, who ran into the water to avoid them, mistook for fierceness. To this day their manners remain the same. They have been observed to enter a tent, and actually pull some meat from beneath the head of a sleeping seaman. The Gauchos also have frequently in the evening killed them, by holding out a piece of meat in one hand, and in the other a knife ready to stick them. As far as I am aware, there is no other instance in any part of the world, of so small a mass of broken land, distant from a continent, possessing so large an aboriginal quadruped peculiar to itself. Their numbers have rapidly decreased; they are already banished from that half of the island which lies to the eastward of the neck of land between St. Salvador Bay and Berkeley Sound. Within a very few years after these islands shall have become regularly settled, in all probability this fox will be classed with the dodo, as an animal which has perished from the face of the earth. At night (17th) we slept on the neck of land at the head of Choiseul Sound, which forms the south-west peninsula. The valley was pretty well sheltered from the cold wind; but there was very little brushwood for fuel. The Gauchos, however, soon found what, to my great surprise, made nearly as hot a fire as coals ; this was the skeleton of a bullock lately killed, from which * I have reason, however, to suspect that there is a field-mouse. The common European rat and mouse have roamed far from the habitations of the settlors. The common hog lias also run wild on one islet : all are of a black colour : the hoars are very fierce, and have great tusks. t The "culpeu" is the Canis Magellanicus brought home hv Captain King from the Strait of Magellan. It is common in Chile CHAP, ix.] ART IX MAKING A FIRE. 185 the flesh Lad been picked by tbc carrion-hawks. They told me that in winter they often killed a beast, cleaned the flesh from the bones with their knives, and then with these same bones roasted the meat for their suppers. 18th. — It rained during nearly the whole day. At night we managed, however, with our saddle-cloths to keep ourselves pretty well dry and warm; but the ground on which we slept was on each occasion nearly in the state of a bog, and there was not a dry spot to sit down on after our day's ride. I have in another part stated how singular it is that there should be absolutely no trees on these islands, although Tierra del Fuego is covered by one large forest. The largest bush in the island (belonging to the family of Com- positse) is scarcely so tall as our gorse. The best fuel is afforded by a green little bush about the size of common heath, which has the useful property of burning while fresh and green. It was very surprising to see the Gauchos, in the midst of rain and everything soaking wet, with nothing more than a tinder-box and piece of rag, immediately make a fire. They sought beneath the tufts of grass and bushes for a few dry twigs, and these they rubbed into fibres ; then surrounding them with coarser twigs, something like a birds' nest, they put the rag with its spark of fire in the middle and covered it up. The nest being then held up to the wind, by degrees it smoked more and more, aud at last burst out in flames. I do not think any other method would have had a chance of succeeding with such damp materials. 19th. — Each morning, from not having ridden for some time previously, I was very stiff. I was surprised to hear the Gauchos, who have from infancy almost lived on horseback, say that, under similar circumstances, they always suffer. St. Jago told me, that having been confined for three months by illness, he went oiit hunting wild cattle, and in conseqitence, for the next two days, his thighs were so stiff that he was obliged to lie in bed. This shows that the Gauchos, although they do not appear to do so, yet really must exert much muscular effort in riding. The hunting wild cattle, in a country so difficult to pass as this is on account of the swampy ground, must be very hard work. The Gauchos say they often pass at full speed over ground which would be impassable at a slower pace ; in the same manner as a man is able to skate over thin ice. When hunting, the party endeavours to get as close as possible to the herd without being discovered. Each 186 FALKLAND ISLANDS. [CHAP. ix. man carries four or five pair of the bolas; these he throws one after the other at as many cattle, which, when once entangled, are left for some days, till they become a little exhausted by hunger and struggling. They are then let free and driven towards a small herd of tame animals, which have been brought to the spot on purpose. From their previous treatment, being too much terrified to leave the herd, they are easily driven, if their strength last out, to the settlement. The weather continued so very bad that we determined to make a push, and try to reach the vessel before night. From, the quantity of rain which had fallen, the surface of the whole country was swampy. I suppose my horse fell at least a dozen times, and sometimes the whole six horses were floundering in the mud together. All the little streams are bordered by soft peat, which makes it very difficult for the horses to leap them without falling. To complete our discomforts we were obliged to cross the head of a creek of the sea, in which the water was as high as our horses' backs; and the little waves, owing to the violence of the wind, broke over us, and made us very wet and cold. Even the iron- framed Gauchos professed themselves glad when they reached the settlement, after our little excursion. The geological structure of these islands is in most respects simple. The lower country consists of clay-slate and sandstone, containing fossils, very closely related to, but not identical with, those found in the Silurian formations of Europe ; the hills are formed of white granular quartz rock. The strata of the latter are frequently arched with perfect symmetry, and the appearance of some of the masses is in consequence most singular. Pernety * has devoted several pages to the description of a Hill of Kuins, the successive strata of which he has justly compared to the seats of an amphitheatre. The quartz rock must have been quite pasty when it underwent such remarkable flexures without being shattered into fragments. As the quartz insensibly passes into the sand- stone, it seems probable that the former owes its origin to the sandstone having been heated to such a degree that it became viscid, and upon cooling crystallized. While in the soft state it must have been pushed up through the overlying beds. In many parts of the island the bottoms of the valleys are * Pernety, Voyage aux Isles Malouiuc?, p. 52G. i-iiAi\ ix.] STREAMS OF STONES. 187 covered in an extraordinary manner by myriads of great loose angular fragments of the quartz rock, forming " streams of stones." These have been mentioned with surprise by every voyager since the time of Pernety. The blocks are not waterworn, their angles being only a little blunted ; they vary in size from one or two feet in diameter to ten, or even more than twenty times as much. They are not thrown together into irregular piles, but are spread out into level sheets or great streams. It is not possible to ascertain their thickness, but the water of small streamlets can be heard trickling through the stones many feet below the surface. The actual depth is probably great, because the crevices between the lower fragments must long ago have been filled up with sand. The width of these sheets of stones varies from a few hundred feet to a mile ; but the peaty soil daily encroaches on the borders, and even forms islets wherever a few fragments happen to lie close together. In a valley south of Berkeley Sound, which some of our party called the " great valley of fragments," it was necessary to cross an uninterrupted band half a mile wide, by jumping from one pointed stone to another. So large were the fragments, that being overtaken by a shower of rain, I readily found shelter beneath one of them. Their little inclination is the most remarkable circumstance in these '" streams of stones." On the hill-sides I have seen them sloping at an angle of ten degrees with the horizon ; but in some of the level, broad-bottomed valleys, the inclination is only just sufficient to be clearly perceived. On so rugged a surface there waa no means of measuring the angle; but to give a common illustration, I may say that the slope would not have checked the speed of an English mail-coach. In some places, a continuous stream of these fragments followed up the course of a valley, and even extended to the very crest of the hill. On these crests huge masses, exceeding in dimensions any small building, seemed to stand arrested in their headlong course : there, also, the curved strata of the archways lay piled on each other, like the ruins of some vast and ancient cathedral. In endeavouring to describe these scenes of violence one is tempted to pass from one simile to another. We may imagine that streams of white lava had flowed from many parts of the mountains into the lower country, and that when solidified they had been rent by some enormous convulsion into myriads of fragments. The expression "streams of stones," 188 FALKLAND ISLANDS. [CHAP. ix. •which immediately occurred to every one, conveys the same idea. These scenes are on the spot rendered more striking by the contrast of the low rounded forms of the neighbouring hills. I was interested by finding on the highest peak of one range (about 700 feet above the sea) a great arched fragment, lying on its convex side, or back downwards. Must we believe that it was fairly pitched up in the air, and thus turned? Or, with more probability, that there existed formerly a part of the same range more elevated than the point on -which this monument of a great convulsion of nature now lies. As the fragments in the valleys are neither rounded nor the crevices filled up with sand, we must infer that the period of violence was subsequent to the land having been raised above the waters of the sea. In a transverse section within these valleys, the bottom is nearly level, or rises biit very little towards either side. Hence the fragments appear to have travelled from the head of the valley ; but in reality it seems more probable that they have been hurled down from the nearest slopes ; and that since, by a vibratory movement of overwhelming force,* the fragments have been levelled into one continuous sheet. If during the earthquake f which in 1835 overthrew Concepcion, in Chile, it was thought wonderful that small bodies should havo been pitched a few inches from the ground, what must we say to a movement which has caused fragments many tons in weight, to move onwards like so much sand on a vibrating board, and find their level? I have seen, in the Cordillera of the Andes, the evident marks where stupendous mountains have been broken into pieces like so nmch thin crust, and the strata thrown on their vertical edges; but never did any scene, like these "streams of stones," so forcibly convey to my mind the idea of a convulsion, of which in historical records we might in vain seek for any counter- part : yet the progress of knowledge will probably some day give a simple explanation of this phenomenon, as it already has of the so long-thought inexplicable transportal of the erratic boulders, which are strewed over the plains of Europe. * " Nous n'avons pas etc moins saisis d'e'tonnement a la vile cle 1'innora- brable quantite cle pierrcs do toutes grandeurs, bouleverse'es les unes sur les autres, et Dependant rauge'es, comme si ellcs avoient etc araoncele'cs ne'gligemnient pour remplir des ravins.

I have before described the carrion-vulture or Polyborus. There are some other hawks, owls, and a few small land-birds. The water-fowl are particularly numerous, and they must formerly, from the accounts of the old navigators, have been much more so. One day I observed a cormorant playing with a fish which it had caught. Eight times successively the bird let its prey go, then dived after it, and although in deep water, brought it each time to the surface. In the Zoological Gardens I have seen the otter treat a fish in the same manner, much as a cat does a mouse : I do not know of any other instance where dame Nature appears so wilfully cruel. Another day, having placed myself between a penguin (Aptenodytes demersa) and the water, I was much amused by watching its habits. It was a bravo bird ; and till reaching the sea, it regularly fought and drove me backwards. Nothing less than heavy blows would have stopped him ; every inch he gained he firmly kept, standing close before me erect and determined. When thus opposed he continually rolled his head from side to side, in a very odd manner, as if the power of distinct vision lay only in the anterior and basal part of each eye. This bird is commonly called the jackass penguin, from its habit, while on shore, of throwing its head backwards, and making a loud strange noise, very like the braying of an ass; but while at sea, and undisturbed, its note is very deep and solemn, and is often heard in the night-time. In diving, its little wings are used as fins ; but on the land, as front legs. When crawling, it may be said on four legs, through the tussocks or on the side of a grassy cliff, it moves so very quickly that it might easily be mistaken for a quadruped. When at sea and fishing, it comes to the surface for the purpose of breathing with such a spring, and dives again so instantaneously, that I defy any one at first sight to be sure that it was not a fish leaping for sport. Two kinds of geese frequent the Falklands. The upland species (Anas Magellauica) is common, in pairs and in small flocks, throughout the island. They do not migrate, but build on the small outlying islets. This is supposed to be from fear of the foxes : and it is perhaps from the same cause that these birds, though very tame by day, are shy and wild in the dusk of the evening. They live entirely on vegetable matter. The rock-goose so called from living exclusively on the sea-beach (Anas antarctica), 190 FALKLAND ISLANDS. [CHAP. is. is common both here and on the west coast of America, as far north as Chile. In the deep and retired channels of Tierra del Fuego, the snow-white gander, invariably accompanied by his darker consort, and standing close by each other on some distant rocky point, is a common feature in the landscape. In these islands a great loggerheaded duck or goose (Anas brachyptera), which sometimes weighs twenty-two pounds, is very abundant. These birds were in former days called, from their extraordinary manner of paddling and splashing upon the water, race-horses; but now they are named, much more appro- priately, steamers. Their wings are too small and weak to allow of flight, but by their aid, partly swimming and partly flapping the surface of the water, they move very quickly. The manner is something like that by which the common house-duck escapes when pursued by a dog ; but I am nearly sure that the steamer moves its wings alternately, instead of both together, as in other birds. These clumsy, loggerheaded ducks make such a noise and splashing, that the effect is exceedingly curious. Thus we find in South America three birds which use their wings for other purposes besides flight; the penguin as fins, the steamer as paddles, and the ostrich as sails : and the Apteryz of New Zealand, as well as its gigantic extinct prototype the Deinornis, possess only rudimentary representatives of wings. The steamer is able to dive only to a very short distance. It feeds entirely on shell-fish from the kelp and tidal rocks : hence the beak and head, for the purpose of breaking them, are surprisingly heavy and strong : the head is so strong that I have scarcely been able to fracture it with my geological hammer ; and all our sportsmen soon discovered how tenacious these birds were of life. When in the evening pluming themselves in a flock, they make the same odd mixture of sounds which bull-frogs do within the tropics. In Tierra del Fuego, as well as at the Falkland Islands, I made many observations on the lower marine animals,* but they are of * I was surprised to find, on counting the eggs of a large white Doris (this sea-slug was three and a half inches long), how extraordinarily numerous they were. From t\vo to five eggs (each three-thousandths of an inch in diameter) were contained in a spherical little case. These were arranged two deep in transverse rows forming a ribbon. The ribbon adhered by its edge to the rock in an oval spire. One which I found, measured nearly twenty inches in length and half in breadth. By counting how many balls were contained in a tenth of an inch in the row, CHAP, ix.] ZOOPHYTES. 191 little general interest. I will mention only one class of facts, relating to certain zoophytes in the more highly organized division of that class. Several genera (Flustra, Eschara, Cellaria, Crisia, and others) agree in having singular moveable organs (like those of Flustra avicularia, found in the European seas) attached to their cells. The organ, in the greater number of cases, very closely resembles the head of a vulture ; but the lower mandible can be opened much wider than in a real bird's beak. The head itself possesses considerable powers of movement, by means of a short neck. In one zoophyte the head itself was fixed, but the lower jaw free : in another it was replaced by a triangular hood, with a beautifully-fitted trap-door, which evidently answered to the lower mandible. In the greater number of species, each cell was provided with one head, but in others each cell had two. The young cells at the end of the branches of these corallines contain quite immature polypi, yet the vulture-heads attached to them, though small, are in every respect perfect. When the polypus was removed by a needle from any of the cells, these organs did not appear in the least affected. When one of the vulture-like heads was cut off from the cell, the lower mandible retained its power of opening and closing. Perhaps the most singular part of their structure is, that when there were more than two rows of cells on a branch, the central cells were furnished with these appendages, of only one-fourth the size of the outside ones. Their movements varied according to the species ; but in some I never saw the least motion ; while others, with the lower mandible generally wide open, oscillated backwards and forwards at the rate of about five seconds each turn ; others moved rapidly and by starts. When touched with a needle, the beak generally seized the point so firmly, that the whole branch might be shaken. These bodies have no relation whatever with the production of the eggs or gemmules, as they are formed before the young polypi appear in the cells at the end of the growing branches ; as they move independently of the polypi, and do not appear to be in any way connected with them ; and as they differ in size on the outer and how many rows in an equal length of the ribbon, on the most moderate computation there were six hundred thousand eggs. Yet this Doris was certainly not very common : although I was often searching under the stones, I saw only seven individuals. No fallacy is more common with naturalists, than that the numbers of an individual species depend on its powers of propagation. 192 FALKLAND ISLANDS. [CHAI-. ix. and inner rows of cells, I have little doubt, that in their functions, they are related rather to the horny axis of the branches than to the polypi in the cells. The fleshy appendage at the lower extremity of the sea-pen (described at Bahia Blanca) also forms part of the zoophyte, as a whole, in the same manner as the roots of a tree form part of the whole tree, and not of the individual leaf or flower-buds. In another elegant little coralline (Crisia?), each cell was fur- nished with a long-toothed bristle, which had the power of moving quickly. Each of these bristles and each of the vulture-like heads generally moved quite independently of the others, but sometimes all on both sides of a branch, sometimes only those on one side, moved together coinstantaneously ; sometimes each moved in regular order one after another. In these actions we apparently behold as perfect a transmission of will in the zoophyte, though composed of thousands of distinct polypi, as in any single animal. The case, indeed, is not different from that of the sea-pens, which, when touched, drew themselves into the sand on the coast of Bahia Blanca. I will state one other instance of uniform action, though of a very different nature, in a zoophyte closely allied to Clytia, and therefore very simply organized. Having kept a large tuft of it in a basin of salt-water, when it was dark I found that as often as I rubbed any part of a branch, the whole became strongly phosphorescent with a green light : I do not think I ever saw any object more beautifully so. But the remarkable circumstance was, that the flashes of light always proceeded up the branches, from the base towards the extremities. The examination of these compound animals was always very interesting to me. What can be more remarkable than to see a plant-like body producing an egg, capable of swimming about and of choosing a proper place to adhere to, which then sprouts into branches, each crowded with innumerable distinct animals, often of complicated organizations? The branches, moreover, as we have just seen, sometimes possess organs capable of movement and independent of the polypi. Surprising as this union of separate individuals in a common stock must always appear, every tree displays the same fact, for buds must be considered as individual plants. It is, however, natural to consider a polypus, furnished with a mouth, intestines, and other organs, as a distinct individual, whereas the individuality of a leaf-bud is not easily realised ; so ( IIAP. ix.] COMPOUND ANIMALS. 193 that the union of separate individuals in a common body is more striking in a coralline than in a tree. Our conception of a com- pound animal, where in some respects the individuality of each is not completed, may be aided, by reflecting on the production of two distinct Creatures by bisecting a single one •with a knife, or where Nature herself performs the task of bisection. We may consider the polypi in a zoophyte, or the buds in a tree, as cases where the division of the individual has not been completely effected. Certainly in the case of trees, and judging from analogy in that of corallines, the individuals propagated by buds seem more intimately related to each other, than eggs or seeds are to their parents. It seems now pretty well established that plants propagated by buds all partake of a common duration of life ; and it is familiar to every one, what singular and numerous peculiarities are transmitted with certainty, by buds, layers, and grafts, which by seminal propagation never or only casually reappear. 194: TIERRA DEL FUEGO.

TIERKA DEL FUEGO. December TTth, 1832. — Having now finished with Patagonia and the Falkland Islands, I will describe our first arrival in Tierra del Fuego. A little after noon we doubled Cape St. Diego, and entered the famous strait of Le Maire. We kept close to the Fuegian shore, but the outline of the rugged, inhospitable Staten- land was visible amidst the clouds. In the afternoon we anchored in the Bay of Good Success. While entering we were saluted in a manner becoming the inhabitants of this savage land. A group of Fuegians partly concealed by the entangled forest, were perched on a wild point overhanging the sea ; and as we passed by, they sprang up and waving their tattered cloaks sent forth a loud and sonorous shout. The savages followed the ship, and just before dark we saw their fire, and again heard their wild cry. The harbour consists of a fine piece of water half surrounded by low rounded mountains of clay-slate, which are covered to the water's edge by one dense gloomy forest. A single glance at the landscape was sufficient to show me how widely different it was from anything I had ever beheld. At night it blew a gale of wind, and heavy squalls from the mountains swept past us. It would have been a bad time out at sea, and we, as well as others, may call this Good Success Bay. In the morning the Captain sent a party to communicate with CHAP, x.] INTERVIEW WITH THE NATIVES. 195 the Fuegians. When we came within hail, one of the four natives who were present advanced to receive us, and began to shout most vehemently, wishing to direct us where to land. When we were on shore the party looked rather alarmed, but continued talking and making gestures with great rapidity. It was without exception the most curious and interesting spectacle I ever beheld : I could not have believed how wide was the difference between savage and civilized man : it is greater than between a wild and domesticated animal, inasmuch as in man there is a greater power of improve- ment. The chief spokesman was old, and appeared to be the head of the family ; the three others were powerful young men, about six feet high. The women and children had been sent away. These Fuegians are a very different race from the stunted, miserable wretches farther westward; and they seem closely allied to the famous Patagonians of the Strait of Magellan. Their only garment consists of a mantle made of guanaco skin, with the wool outside : this they wear just thrown over their shoulders, leaving their persons as often exposed as covered. Their skin is of a dirty coppery red colour. The old man had a fillet of white feathers tied round his head, which partly confined his black, coarse, and entangled hair. His face was crossed by two broad transverse bars ; one, painted bright red, reached from ear to car and included the upper lip ; the other, white like chalk, extended above and parallel to the first, so that even his eyelids were thus coloured. The other two men were ornamented by streaks of black powder, made of charcoal. The party altogether closely resembled the devils which come on the stage in plays like Der Freischutz. Their very attitudes were abject, and the expression of their countenances distrustful, surprised, and startled. After we had presented them with some scarlet cloth, which they immediately tied round their necks, they became good friends. This was shown by the old man patting our breasts, and making a chuckling kind of noise, as people do when feeding chickens. I walked \\ith the old man, and this demonstration of friendship was repeated several times; it was concluded by three hard slaps, which were given me on the breast and back at the same time. He then bared his bosom for me to return the compliment, which being done, he seemed highly pleased. The language of these people, according to our notions, scarcely deserves to be called articulate. Captain Cook has 196 TIERRA DEL FUEGO. [CHAP. x. compared it to a man clearing Ins throat, but certainly no European ever cleared his throat with so many hoarse, guttural, and clicking sounds. They are excellent mimics : as often as we coughed or yawned. or made any odd motion, they immediately imitated us. Some of our party began to squint and look awry ; but one of the young Fuegians (whose whole face was painted black, excepting a white band across his eyes) succeeded in making far more hideous grimaces. They could repeat with perfect correctness each word in any sentence we addressed them, and they remembered such words for some time. Yet we Europeans all know how difficult it is to distinguish apart the sounds in a foreign language. Which of us, for instance, could follow an American Indian through a sentence of more than three words ? All savages appear to possess, to an uncommon degree, this power of mimicry. I was told, almost in the same words, of the same ludicrous habit among the Caffres : the Australians, likewise, have long been notorious for being able to imitate and describe the gait of any man, so that he may be recognized. How can this faculty be explained ? is it a consequence of the more practised habits of perception and keener senses, common to all men in a savage state, as compared with those long civilized ? When a song was struck up by our party, I thought the Fuegians would have fallen down with astonishment. With equal surprise they viewed our dancing ; but one of the young men, when asked, had no objection to a little waltzing. Little accustomed to Euro- peans as they appeared to be, yet they knew and dreaded our fire- arms; nothing would tempt them to take a gun in their hands. They begged for knives, calling them by the Spanish word "cuchilla." They explained also what they wanted, by acting as if they had a piece of blubber in their mouth, and then pretending to cut instead of tear it. I have not as yet noticed the Fuegians whom we had on board. During the former voyage of the Adventure and Beagle in 1826 to 1830, Captain Fitz Boy seized on a party of natives, as hostages for the loss of a boat, which had been stolen, to the great jeopardy of a party employed on the survey ; and some of these natives, as well as a child whom he bought for a pearl-button, he took with him to England, determining to educate them and instruct them in religion at his own expense. To settle these natives in their own country, CHAP, x.] FUEGIANS ON BOARD. 197 was one chief .inducement to Captain Fitz Roy to undertake our present voyage; and before the Admiralty had resolved to send out this expedition, Captain Fitz Eoy had generously chartered a vessel, and would himself have taken them back. The natives were accompanied by a missionary, R. Matthews; of whom and of the natives, Captain Fitz Roy has published a full and excellent account. Two men, one of whom died in England of the small-pox, a boy and a little girl, were originally taken; and we had now on board, York Minster, Jemmy Button (whose name expresses his purchase- money), and Fuegia Basket. York Minster was a full-grown, short, thick, powerful man : his disposition was reserved, taciturn, morose, and when excited violently passionate; his affections were very strong towards a few friends on board ! his intellect good. Jemmy Button was a universal favourite, but likewise passionate ; the expression of his face at once showed his nice disposition. He was merry and often laughed, and was remarkably sympathetic with any one in pain : when the water was rough, I was often a little sea- sick, and he used to come to me and say in a plaintive voice, " Poor, poor fellow ! " but the notion, after his aquatic life, of a man being sea-sick, was too ludicrous, and he was generally obliged to turn on one side to hide a smile or laugh, and then he would repeat his " Poor, poor fellow ! " He was of a patriotic disposition ; and he liked to praise his own tribe and country, in which he truly said there were "plenty of trees,'' and he abused all the other tribes: he stoutly declared that there was no Devil in his land. Jemmy was short, thick, and fat, but vain of his personal appear- ance ; he used always to wear gloves, his hair was neatly cut, and he was distressed if his well-polished shoes were dirtied. He was fond of admiring himself in a looking glass; and a merry-faced little Indian boy from the Rio Negro, whom we had for some months on board, soon perceived this, and used to mock him : Jemmy, who was always rather jealous of the attention paid to this little boy, did not at all like this, and used to say, with rather a contemptuous twist of his head, " Too much skylark." It seems yet wonderful to me, when I think over all his many goad qualities, that he should have been of the same race, and doubtless partaken of the same character, with the miserable, degraded savages whom we first met here. Lastly, Fuegia Basket was a nice, modest, reserved young girl, with a rather pleasing but sometimes sullen expression, and very quick in learning anything, especially 198 TIERRA DEL FUEGO. [CHAP. x. languages, ^his she showed in picking tip some Portuguese and Spanish, Avhen left on shore for only a short time at Rio de Janeiro and Monte Video, and in her knowledge of English. York Minster was very jealous of any attention paid to her ; for it was clear he determined to marry her as soon as they were settled on shore. Although all three could both speak and understand a good deal of English, it was singularly difficult to obtain much in- formation from them, concerning the habits of their countrymen : this was partly owing to their apparent difficulty in understanding the simplest alternative. Every one accustomed to very younjj children, knows how seldom one can get an answer even to so simple a question as whether a thing is black or white ; the idea of black or white seems alternately to fill their minds. So it was with these Fuegians, and hence it was generally impossible to find out, by cross-questioning, whether one had rightly understood anything which they had asserted. Their sight was remarkably acute : it is well known that sailors, from long practice, can make out a distant object much better than a landsman ; but both York and Jemmy were much superior to any sailor on board : several times they have declared what some distant object has been, and though doubted by every one, they have proved right, when it has been examined through a telescope. They were quite conscious of this power; and Jemmy, whe'n he had any little quarrel with the officer on watch, would say, " Me see ship, me no tell." It was interesting to watch the conduct of the savages, when we landed, towards Jemmy Button : they immediately perceived the difference between him and ourselves, and held much con- versation one with another on the subject. The old man addressed a long harangue to Jemmy, which it seems was to invite him to stay with them. But Jemmy understood very little of their lan- guage, and was, moreover, thoroughly ashamed of his countrymen. When York Minster afterwards cance on shore, they noticed him in the same way, and told him he ought to shave; yet he had not twenty dwarf hairs on his face, whilst we all wore our untrimmed beards. They examined the colour of his skin, and compared it with ours. One of our arms being bared, they expressed the live- liest surprise and admiration at its whiteness, just in the same way in which I have seen the ourang-outang do at the Zoological Gar- dens. We thought that they mistook two or three of the officers, who were rather shorter and fairer, though adorned with large CHAP, x.] SCENERY OF THE MOUNTAINS. 199 beards, for the ladies of our party. The tallest amongst the Fucgians was evidently much pleased at his height being noticed. When placed back to back with the tallest of the boat's crew, he tried his best to edge on higher ground, and to stand on tiptoe. He opened his mouth to show his teeth, and turned his face for a side view; and all this was done with such alacrity, that I dare say he thought himself the handsomest man in Tierra del Fuego. After our first feeling of grave astonishment was over, nothing could be more ludicrous than the odd mixture of surprise and imitation which these savages every moment exhibited. The next day I attempted to penetrate gome way into the country. Tierra del Fuego may be described as a mountainous land, partly submerged in the sea, so that deep inlets and bays occupy the place where valleys should exist. The mountain sides, except on the exposed western coast, are covered from the water's edge upwards by one great forest. The trees reach to an elevation of between 1000 and 1500 feet, and are succeeded by a band of peat, with minute alpine plants ; and this again is succeeded by the line of perpetual snow, which, according to Captain King, in the Strait of Magellan descends to between 3000 and 4000 feet. To find an acre of level land in any part of the country is most rare. I recollect only one little flat piece near Port Famine, and another of rather larger extent near Goeree Road. In both places, and everywhere else, the surface is covered by a thick bed of swampy peat. Even within the forest, the ground is concealed by a nmss of slowly putrefying vegetable matter, which, from being soaked with water, yields to the foot. Finding it nearly hopeless to push my way through the wood, I followed the course of a mountain torrent. At first, from the waterfalls and number of dead trees, I could hardly crawl along ; but the bed of the stream soon became a little more open, from the floods having swept the sides. I continued slowly to advance for an hour along the broken and rocky banks, and was amply repaid by the grandeur of the scene. The gloomy depth of the ravine well accorded with the universal signs of violence. On every side were lying irregular masses of rock and torn-up trees ; other trees, though still erect, were decayed to the heart and ready to fall. The entangled mass of the thriving and the fallen reminded me of the forests within the tropics — yet there was a difference : 200 TIERRA DEL FUEGO. [CHAP. x. for in these still solitudes, Death, instead of Life, seemed the pre- dominant spirit. I followed the watercourse till I came to a spot, •where a great slip had cleared a straight space down the mountain side. By this road I ascended to a considerable elevation, and obtained a good view of the surrounding woods. The trees all belong to one kind, the Fagus betuloides ; for the number of the other species of Fagus and of the Winter's Bark, is quite incon- siderable. This beech keeps its leaves throughout the year ; but its foliage is of a peculiar brownish-green colour, with a tinge of yellow. As the whole landscape is thus coloured, it has a sombre, dull appearance ; nor is it often enlivened by the rays of the sun. December ZQtk. — One side of the harbour is formed by a hill about 1500 feet high, which Captain Fitz Koy has called after Sir J. Banks, in commemoration of his disastrous excursion, which proved fatal to two men of his party, and nearly so to Dr. Solander. The snow- storm, which was the cause of their misfortune, happened in the middle of January, corresponding to our July, and in the latitude of Durham! I was anxious to reach the summit of this moun- tain to collect alpine plants ; for flowers of any kind in the lower parts are few in number. We followed the same watercourse as on the previous day, till it dwindled away, and we were then compelled to crawl blindly among the trees. These, from the effects of the elevation and of the impetuous winds, were low, thick, and crooked. At length we reached that which from a distance appeared like a carpet of fine green turf, but which, to our vexation, turned out to be a compact mass of little beech-trees about four or five feet high. They were as thick together. as box in the border of a garden, and we were obliged to struggle over the flat but treacherous surface. After a little more trouble we gained the peat, and then the baro slate rock. A ridge connected this hill with another, distant some miles, and more lofty, so that patches of snow were lying on it. As the day was not far advanced, I determined to walk there and collect plants along the road. It would have been very hard work, had it not been for a well-beaten and straight path made by the guanacos; for these animals, like sheep, always follow the same line. When we reached the hill we found it the highest in the immediate neighbourhood, and the waters flowed to the sea in opposite direc- tions. We obtained a wide view over the surrounding country : to the north a swampy moorland extended, but to the south we had a CHAP, x.] CAPE HORN. 201 scene of savage magnificence, well becoming Tierra del Fuego. There was a degree of mysterious grandeur in mountain behind mountain, with the deep intervening valleys, all covered by one thick, dusky mass of forest. The atmosphere, likewise, in this climate, where gale succeeds gale, with rain, hail, and sleet, seems blacker than anysvhere else. In the Strait of Magellan, looking due southward from Port Famine, the distant channels between the mountains appeared from their gloominess to lead beyond the confines of this world. December 1\st. — The Beagle got under way : and on the succeed- ing day, favoured to an uncommon degree by a fine easterly breeze, we closed in with the Barnevelts, and running past Cape Deceit with its stony peaks, about three o'clock doubled the weather- beaten Cape Horn. The evening was calm and bright, and we enjoyed a fine view of the surrounding isles. Cape Horn, how- ever, demanded his tribute, and before night sent us a gale of wind directly in our teeth. We stood out to sea, and on the second day again made the land, when we saw on our weather-bow this notorious promontory in its proper form — veiled in a mist, and its dim outline surrounded by a storm of wind and water. Great black clouds were rolling across the heavens, and squalls of rain, with hail, swept by us with such extreme violence, that the Captain determined to run into Wigwam Cove. This is a snug little harbour, not far from Cape Horn ; and here, at Christmas- eve, we anchored in smooth water. The only thing which reminded us of the gale outside, was every now and then a puff from the mountains, which made the ship surge at her anchors. December 25lagucd us. As there Avere many instruments, clothes, and men on shore, it was thought necessary to frighten them away. The first time a few great guns were fired, when they were far distant. It was most ludicrous to watch through a glass the Indians, as often as the shot struck the water, take up stones, and, as a bold defiance, throw them towards the ship, though about a mile and a half distant! A boat was then sent with orders to fire a few muskets-shots wide of them. The Fuegians hid themselves behind the trees, and for every discharge of the muskets they fired their arrows; all, however, fell short of the boat, and the officer as he pointed at them laughed. This made the Fuegians frantic with passion, and they shook their mantles in vain rage. At List, seeing the balls cut and strike the trees, they ran away, and we were left in peace and quietness. During the former voyage the Fuegians were here very troublesome, and to frighten them a rocket was fired at night over their wigwams ; it answered effec- tually, and one of the officers told me that the clamour first raised, and the barking of the dogs, was quite ludicrous in contrast with the profound silence which in a minute or two afterwards prevailed. The next morning not a single Fuegian was in the neighbourhood. When the Beagle was here in the month of February, I started one morning at four o'clock to ascend Mount Tarn, which is 2GOO feet high, and is the most elevated point in this immediate district. We went in a boat to the foot of the mountain (but unluckily not to the best part), and then began our ascent. The forest com- mences at the line of high-water mark, and during the first two hours I gave over all hopes of reaching the summit. So thick was the wood, that it was necessary to have constant recourse to the compass ; for every landmark, though in a mountainous country, was completely shut out. In the deep ravines, the death-like scene of desolation exceeded all description ; outside it was blowing a gale, but in these hollows, not even a breath of wind stirred the leaves of the tallest trees. So gloomy, cold, and wet was every part, that not even the fungi, mosses, or ferns could flourish. In the valleys it was scarcely possible to crawl along, they were so completely barricaded by great mouldering trunks, which had fallen down in every direction. When passing over these natural bridges, one's course was often arrested by sinking knee deep into the rotten wood; at other times, when attempting to lean against a firm tree, one was startled by finding a mass of decayed 224 TIERRA DEL FUEGO. [CHAP. xi. matter ready to fall at the slightest touch. "We at last found ourselves among the stunted trees, and then soon reached the bare ridge, which conducted us to the summit. Here was a view characteristic of Tierra del Fuego; irregular chains of hills, mottled with patches of snow, deep yellowish-green valleys, and arms of the sea intersecting the land in many directions. The strong wind was piercingly cold, and the atmosphere rather hazy, so that we did not stay long on the top of the mountain. Our descent was not quite so laborious as our ascent; for the weight of the body forced a passage, and all the slips and falls were in the right direction. I have already mentioned the sombre and dull character of the evergreen forests,* in which two or three specits of trees grow, to the exclusion of all others. Above the forest land, there are many dwarf alpine plants, which all spring from the mass of peat, and help to compose it: these plants are very remarkable from their close alliance with the species growing on the mountains of Europe, though so many thousand miles distant. The central part of Tierra del Fuego, where the clay-slate formation occurs, is most favourable to the growth of trees ; on the outer coast the poorer granitic soil, and a situation more exposed to the violent winds, do not allow of their attaining any great size. Near Port Famine I have seen more large trees than anywhere else : I measured a Winter's Bark which was four feet six inches in girth, and several of the beech were as much as thirteen feet. Captain King also mentions a beech which was seven feet in diameter seventeen feet above the roots. There is one vegetable production deserving notice from its importance as an article of food to the Fuegians. It is a globular, bright-yellow fungus, which grows in vast numbers on the beech- trees. When young it is elastic and turgid, with a smooth surface ; but when mature it shrinks, becomes tougher, and has its entire * Captain Fitz Roy informs me that in April (our October), the leaves of those trees which grow near the base of the mountains, change colour, but not those on the more elevated parts. I remember having read some observations, showing that in England the leaves fall earlier in a warm and fine autumn than in a late and cold one. The change in the colour being here retarded in the more elevated, and therefore colder situations, must be owing to the same general law of vegetation. The trees of Tierra del Fuego during no part of the year entirely shed their leaves. 1834.] ZOOLOGY. 225 surface deeply pitted or honey-combed, as represented in tho accompanying wood-cut. This fungus belongs to a new and curious genus ; * I found a second species on another species of beech in Chile ; and Dr. Hooker informs me, that just lately a third species has been dis- covered on a third species of beech in Van Diemen's Land. How singular is this relationship between parasitical fungi and the trees on which they grow, in distant parts of the world ! In Tierra del Fuego the fungus in its tough and mature state is collected in large quantities by the women and children, and is eaten uncooked. It has a mucilaginous, slightly sweet taste, with a faint smell like that of a mushroom. With the exception of a few berries, chiefly of a dwarf arbutus, the natives cat no vegetable food besides this fungus. In New Zealand, before the introduction of the potato, the roots of the fern were largely consumed ; at the present time, I believe, Tierra del Fuego is the only country in the world where a cryptogamic plant affords a staple article of food. . The zoology of Tierra del Fuego, as might have been expected from the nature of its climate and vegetation, is very poor. Of mammalia, besides whales and seals, there is one bat, a kind of mouse (Ecithrodon chinchilloides), two true mice, a ctenomys allied to or identical with the tucutuco, two foxes (Cam's Magel- lanicus and C. AzaraV), a sea-otter, the guanaco, and a deer. Most of these animals inhabit only the drier eastern parts of the country ; and the deer has never been seen south of the Strait of Magellan. Observing the general correspondence of the cliffs of soft sandstone, mud, and shingle, on the opposite sides of the Strait, and on some intervening islands, one is strongly tempted to believe that the land was once joined, and thus allowed animals so delicate and helpless as the tucutuco and Reithrodon to pass over. The corre- spondence of the cliffs is far from proving any junction ; because such cliffs generally are formed by the intersection of sloping * Described from my specimens, and notes by the Eev. J.

[< MAI-. xi. deposits, which, before the elevation of the land, had been accu- mulated near the then existing shores. It is, however, a remark- able coincidence, that in the two large islands cut off by the Beagle Channel from the rest of Tit-mi del Fuego, one has cliffs composed of matter that may be called stratified alluvium, which front similar ones on the opposite side of the channel,— while the other is exclusively bordered by old crystalline rocks: in the former, called Navarin Island, both foxes and guanacos occur; but in the latter, Hoste Island, although similar in every respect, and only separated by a channel a little more than half a mile wide, I have the word of Jemmy Button for saying that neither of these animals are found. The gloomy woods are inhabited by few birds : occasionally the plaintive note of a white-tufted tyrant-flycatcher (Myiobius albi- ceps) may be heard, concealed near the summit of the most lofty trees ; and more rarely the loud strange cry of a black wookpecker, with a fine scarlet crest on its head. A little, dusky-coloured wren (Scytalopus Magellanicus) hops in a skulking manner among the entangled mass of the fallen and decaying trunks. But the creeper (Oxyurus tupinieri) is the commonest bird in the country. Throughout the beech forests, high up and low down, in the most gloomy, wet, and impenetrable ravines, it may be met with. This little bird no doubt appears more numerous than it really is, from its habit of following with seeming curiosity any person who enters these silent woods : continually uttering a harsh twitter, it flutters from tree to tree, within a few feet of the intruder's face. It is far from wishing for the modest concealment of the true creeper (Certhia familiaris) ; nor does it, like that bird, run up the trunks of trees; but industriously, after the manner of a willow-wren, hops about, and searches for insects on every twig and branch. In the more open parts, three or four species of finches, a thrush, a starling (or Icterus), two Opetiorhynchi, and several hawks and owls occur. The absence or any species whatever in the whole class of Eep- tiles, is a marked feature in the zoology of this country, as well as in that of the Falkland Islands. I do not ground this statement merely on my own observation, but I heard it from the Spanish inhabitants of the latter place, and from Jemmy Button with regard to Tierra del Fuego. On the banks of the Santa Cruz, in 50° south, I saw a frog ; and it is not improbable that these animals, as well as lizards, may be found as far south as the Strait ls:!l.l GREAT SEA- WEED. 227 of Magellan, where the country retains the character of Patagonia; Imt within the damp and cold limit of Tierra del Fuego not one occurs. That the climate would not have suited some of the orders, such as lizards, might have been foreseen; but with respect to frogs, this was not so obvious. Beetles occur in very small numbers : it was long before I could believe that a country as large as Scotland, covered with vegetable productions and with a variety of stations, could be so unproductive. The few which I found were alpine species (Harpalidse and Hete- romida?) living under stones. The vegetable-feeding Chrysomelida), so eminently characteristic of the Tropics, are hero almost entirely absent ; * I saw very few flics, butterflies, or bees, and no crickets or Orthoptera. In the pools of water I found but a few aquatic beetles, and not any fresh-water shells: Succinea at first appears an excep- tion ; but here it must be called a terrestrial shell, for it lives on the damp herbage far from water. Land-shells could be pro- cured only in the same alpine situations with the beetles. I have already contrasted the climate as well as the general appearance of Tierra del Fuego with that of Patagonia; and the difference is strongly exemplified in the entomology. 1 do not believe they have one species in common; certainly the general character of the insects is widely different. If we turn from the land to the sea, we shall find the latter as abundantly stocked with living creatures as the former is poorly so. In all parts of the world a rocky and partially protected shore perhaps supports, in a given space, a greater number of individual animals than any other station. There is one marine production which, from its importance, is worthy of a particular history. It is the kelp, or Macrocystis pyrifcra. This plant grows on every rock from low-water mark to a great depth, both on the outer coast and within the channels.! I believe, during tho * I believe I must except one alpine Haltica, and a single specimen of a Melasoma. Mr. "VVaterhouse informs me, that of the Harpalidse there are eight or nine species — the forms of the greater number being very pecu- liar; of Heteromera, four or five species; of Rhyncophora, six or seven ; and of the following families one species in each : Staphylinidse, Elate- ridze, Cebrionidse, Melolonthidce. The species in the otiier orders are even fewer. In all the orders, the scarcity of the individuals is even more remarkable than that of the species. Most of the Colcoptera have been carefully described by Mr. Waterhouse in the Annals of Nat. Hist. f Its geographical range is remarkably wide ; it is found from the extreme southern islets near Cape Horn, as far north ou the eastern coast 22S TIEBBA.DEL FUEGO [CHAP. XT. voyages of the Adventure and Beagle, not one rock near the surface was discovered which was not buoyed by this floating weed. The good service it thus affords to vessels navigating near this stormy land is evident ; and it certainly has saved many a one from being wrecked. I know few things more surprising than to see this plant growing and flourishing amidst those great breakers of the western ocean, which no mass of rock, let it be ever so hard, can long resist. The stem is round, slimy, and smooth, and seldom lias a diameter of so much as an inch. A few taken together are sufficiently strong to support the weight of the large loose stones, to which in the inland channels they grow attached ; and yet some of these stones were so heavy that when drawn to the surface, they could scarcely be lifted into a boat by one person. Captain Cook, in his second voyage, says, that this plant at Kerguelen Land rises from a greater depth than twenty-four fathoms ; '•' and as it does not grow in a perpendicular direction, but makes a very acute angle with the bottom, and much of it afterwards spreads many fathoms on the surface of the sea, I am well warranted to say that some of it grows to the length of sixty fathoms and upwards." I do not suppose the stem of any other plant attains so great a length as three hundred and sixty feet, as stated by Captain Cook. Captain Fitz Eoy, moreover, found it growing * up from the greater depth of forty-five fathoms. The beds of this sea-weed, even when of not great breadth, make excellent natural floating breakwaters. It is quite curious to see, in an exposed harbour, how soon the waves from the open sea, as they travel through the straggling stems, sink in height, and pass into smooth water. The number of living creatures of all Orders, whose existence intimately depends on the kelp, is wonderful. A great volume might be written, describing the inhabitants of one of these beds (according to information given me by Mr. Stokes) at lat. 43°,— but on the western coast, as Dr. Hooker tells me, it extends to the R. 8au Francisco in California, and perhaps even to Kamtschatka. We thus have an immense range in latitude; and as Cook, who must Lave been well acquainted with the species, found it at Kerguelen Land, no less than 140° in longitude. * Voyages of the Adventure and Beagle, vol. i. p. 3C3.— It appears that sea-weed grows extremely quick. Mr. Stepheuson found (Wilson's A'oynge round Scotland, vol. ii. p. 228) that a rock uncovered only at spring-tides, which had been chiselled smooth in November, on the follow- ing May, that is, within six months afterwards, was thickly covered with. FOOTS digitatus two feet, and F. csculcutus six feet, in length. 1834] GREAT SEA-WEED. 2:>9 of sea-weed. Almost all the leaves, excepting those that float on the surface, are so thickly incrusted with corallines as to be of a white colour. We find exquisitely delicate structures, some in- habited by simple hydra-like polypi, others by more organized kinds, and beautiful compound Ascidise. On the leaves, also, various patelliform shells, Trochi, uncovered molluscs, and some bivalves are attached. Innumerable Crustacea frequent every part of the plant. On shaking the great entangled roots, a pile of small fish, shells, cuttle-fish, crabs of all orders, sea-eggs, star- fish, beautiful Iloluthuria?, Planarite, and crawling nereidous animals of a multitude of forms, all fall out together. Often as I recurred to a branch of the kelp, I never failed to discover animals of new and curious structures. In Chiloe, where the kelp does not thrive very well, the numerous shells, corallines, and Crustacea are absent; but there yet remain a few of the Flus- traceac, and some compound Ascidirc ; the latter, however, are of different species from those in Tierra del Fuego: we here see the fucus possessing a wider range than the animals which use it as an abode. I can only compare these great aquatic forests of the southern hemisphere with the terrestrial ones in the inter- tropical regions. Yet if in any coiintry a forest was destroyed, I do not believe nearly so many species of animals would perish as would here, from the destruction of the kelp. Amidst the leaves of this plant numerous species of fish live, which nowhere else could find food or shelter ; with their destruction the many cor- morants and other fishing birds, the otters, seals, and porpoises, would soon perish also; and lastly, the Fuegian savage, the miserable lord of this miserable land, would redouble his cannibal feast, decrease in numbers, and perhaps cease to exist. June 8th. — We weighed anchor early in the morning and left Port Famine. Captain Fitz Roy determined to leave the Strait of Magellan by the Magdalen Channel, which had not long been discovered. Our course lay due south, down that gloomy passage which I have before alluded to as appearing to lead to another and worse world. The wind was fair, but the atmosphere was very thick ; so that we missed much curious scenery. The dark ragged clouds were rapidly driven over the mountains, from their summits nearly down to their bases. The glimpses which wo caught through the dusky mass were highly interesting; jagged points, cones of snow, blue glaciers, strong outlines, marked on a 230 MOUNT SARMIENTO. tciui-. xi. lurid sky, were seen at different distances and heights. In the midst of such scenery we anchored at Cape Tarn, close to Mount Sarrniento, which was then hidden in the clouds. At the base of the lofty and almost perpendicular sides of our little cove there was one deserted wigwam, and it alone reminded us that man sometimes wandered into these desolate regions. But it would be difficult to imagine a scene where he seemed to have fewer claims or less authority. The inanimate works of nature— rock, ice, snow, wind, and water— all warring with each other, yet combined against man— here reigned in absolute sovereignty. June $Ht— In the morning we were delighted by seeing the veil of mist gradually rise from Sarmieuto, and display it to our view. This mountain, which is one of the highest in Tierra del Fuego, has an altitude of 6800 feet. Its base, for about an eighth of its total height, is clothed by dusky-woods, and above this a field of snow extends to the summit. These vast piles of snow, which never melt, and seem destined to last as long as the world holds together, present a noble and even sublime spectacle. The outline of the mountain was admirably clear and defined. Owing to the abundance of light reflected from the white and glittering surface, no shadows were cast on any part ; and those lines which intersected the sky could alone be distinguished : hence the mass stood out in the boldest relief. Several glaciers descended in a winding course from the upper great expanse of snow to the sea-coast : they may be likened to great frozen Niagaras ; and perhaps these cataracts of blue ice are full as beautiful as the moving ones of water. By night we reached the western part of the channel ; but the water was so deep that no anchorage could be found. We were in con- sequence obliged to stand off and on in this narrow arm of the sea, during a pitch-dark night of fourteen hours long. June IQth. — In the morning we made the best of our way into the open Pacific. The western coast generally consists of low, rounded, quite barren hills of granite and greenstone. Sir J. Xar- borough called one part South Desolation, because it is "so desolate a land to behold : " and well indeed might he say so. Outside the main islands, there are numberless scattered rocks on which the long swell of the open ocean incessantly rages. We passed out between the East and West Furies ; and a little farther northward there are so many breakers that the sea is called the Milky Way. One sight of such a coast is enough to make a lands- 1834.] CLIMATE AND PRODUCTIONS. 231 man dream for a week about shipwrecks, peril, and death ; aud with this sight we bade farewell for ever to Tierra del Fuego. The following discussion on the climate of the southern parts of the continent with relation to its productions, on the snow-line, on the extraordinarily low descent of the glaciers, and on the zone of perpetual congelation in the antarctic islands, may be passed over by any one not interested in these curious subjects, or the final recapitulation alone may be read. I shall, however, here give only an abstract, and must refer for details to the Thirteenth Chapter and the Appendix of the former edition of this work. On the Climate and Productions of Tierra del Fuego and of the South-ivest Coast. — The following table gives the mean temperature of Tierra del Fuego, the Falkland Islands, and, for comparison, that of Dublin :— Summer Winter Mean of Summer Latitude. TCUII) Temp and Winter. Tierra del Fuego . , 53° 38' S. 50° 33°-08 41°-54 Falkland Islands . . 51 30 S. 51 Dublin .... 53 21 N. 59-54 39'2 49'37 Hence we see that the central part of Tierra del Fuego is colder in winter, and no less than 9^° less hot in summer, than Dublin. According to Von Buch, the mean temperature of July (not the hottest mouth in the year) at Saltenfiord in Norway, is as high as 57°'8, and this place is actually 13° nearer the pole than Port Famine ! * Inhospitable as this climate appears to our feelings, evergreen trees flourish luxuriantly under it. Humming-birds may be seen sucking the flowers, and parrots feeding on the seeds of the Winter's Bark, in lat. 55° S. I have already remarked to what a degree the sea swarms with living creatures; and the shells (such as the Patella?, Fissurells), Chitons, and Barnacles), according to Mr. G. B. Sowerby, are of a much larger size, and of a more vigorous growth, than the analogous species in the northern hemisphere. A large Voluta is abundant in southern Tierra del Fuego and the Falkland Islands. At Bahia Blanca, in lat. 39° S., * With respect to Tierra del Fuego, the results are deduced from the observations by Capt. King (C4eographical Journal, 1830), and those taken on board the Beagle. For the Falkland Islands, I am indebted to Capt. 8ulivan for the mean of the mean temperature (reduced from careful ob- servation at midnight, 8 A.M., noon, and 8 P.M.) of the three hottest months, vi/.

[CHAF. xi. the most abundant shells were three species of Oliva (one of large size), one or two Volutas, and a Terebra. Now, these are amongst the best characterized tropical forms. It is doubtful whether even one small species of Oliva exists on the southern shores of Europe, and there are no species of the two other genera. If a geologist were to find in Jat. 39° on the coast of Portugal a bed containing numerous shells belonging to three species of Oliva, to a Yoluta and Terebra, he would probably assert that the climate at the period of their existence must have been tropical ; but, judging from South America, such an inference might be erroneous. The equable, humid, and windy climate of Tierra del Fuego extends, with only a small increase of heat, for many degrees along the west coast of the continent. The forests, for 600 miles north- ward of Cape Horn, have a very similar aspect. As a proof of the equable climate, even for 300 or 400 miles still further northward, I may mention that in Chiloe (corresponding in latitude with the northern parts of Spain) the peach seldom produces fruit, whilst strawberries and apples thrive to perfection. Even the crops of barley and wheat * are often brought into tfie, houses to be dried and ripened. At Yaldivia (in the same latitude of 40°, with Madrid) grapes and figs ripen, but are not common ; olives seldom ripen even partially, and oranges not at all. These fruits, in corresponding latitudes in Europe, are well known to succeed to perfection; and even in this continent, at the Eio Negro, under nearly the same parallel with Yaldivia, sweet potatoes (convolvulus) are cultivated; and grapes, figs, olives, oranges, water and musk melons, produce abundant fruit. Although the humid and equable climate of Chiloe, and of the coast northward and southward of it, is so unfavourable to our fruits, yet the native forests, from lat. 45° to 38°, almost rival in luxuriance those of the glowing intertropical regions. Stately trees of many kinds, with smooth and highly coloured barks, are loaded by parasitical mono- cotyledonous plants; large and elegant ferns are numerous, and arborescent grasses entwine the trees into one entangled mass to the height of thirty or forty feet above the ground. Palm-trees grow in lat. 37° ; an arborescent grass, very like a bamboo, in 40° ; and another closely allied kind, of great length, but not erect, flourishes even as far south as 45° S. An equable climate, evidently due to the large area of sea coin- * Agiicros, Descrip.

Tree-ferns thrive luxuriantly in Van Diemen's Land (lat. 45°), and I measured one trunk no less than six feet in circumference. An arborescent fern was found by Forster in New Zealand in 46°, where orchideous plants are para- sitical on the trees. In the Auckland Islands, ferns, according to Dr. Dieffenbach,* have trunks so thick and high that they may be almost called tree-ferns ; and in these islands, and even as far south as lat. 55° in the Macquarrie Islands, parrots abound.
