PREFACE. 



J 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 ir. 
consequence of a wish expressed by Captain Fitz Roy, of having 
some scientific person on board, accompanied by an offer from 
him of giving up part of his own accommodations, that I volun- 
teered my services, which received, through the kindness of the 
hydrographer, Captain Beaufort, the sanction of the Lords of 
the Admiralty. As I feel that the opportunities which I en- 
joyed of studying the Natural History of the different countries 
we visited, have been wholly dne to Captain Fitz Roy, 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 Roy 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 account of the Fossil Mammalia, by 
Professor Owen ; of the Living Mammalia, by Mr. Water- 
house ; of the Birds, by Mr. Gould ; of the Fish, by the 
Rev. L. Jenyns ; and of the Reptiles, 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 

* I must take this opportunity of returning my sincere thanks to Mr. Bynoe, 
the surgeon of the Beagle, for his very kind attention to me when I was ill 
t Valuaraiso.

talents and disinterested zeal of the above distinguished authors, 
could not have been undertaken, had it not been for the libe- 
rality of the Lords Commissioners of Her Majesty's Treasury, 
who, through the representation of the Right Honourable the 
Chancellor of the Exchequer, have been pleased to grant a sum 
of one tnousand pounds towards defraying part of the expenses 
of publication. 

I have myself published separate volumes on the ' Structure 
and Distribution of Coral Reefs ;' on the ' Volcanic Islands 
visited during the Voyage of the Beagle ;' and on the ' Geology 
of South America.' The sixth volume of the ' Geological Trans- 
actions ' contains two papers of mine on the Erratic Boulders 
and Volcanic Phenomena of South America. Messrs. Water- 
house, 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 Archipelago is the subject of a separate memoir 
by him, in the ' Linnean Transactions.' The Reverend Professor 
Henslow has published a list of the plants collected by me at 
the Keeling Islands ; and the Reverend J. M. Berkeley has de- 
scribed my cryptogamic plants. 

I shall have the pleasure of acknowledging the great assist- 
ance which I have received from several other naturalists, in the 
course of this and my other works ; but I must be her allowed 
to return my most sincere thanks to the Reverend Professor 
Henslow, who, when I was an under-graduate 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 correspondence directed my endeavours, and 
who, since my return, has constantly rendered me every assist- 
ance which the kindest friend could offer.

POSTSCRIPT. 



I TAKE the opportunity of a new edition of my Journal to 
correct a few errors. At page 83 I have stated that the 
majority of the shells which were embedded with the extinct 
mammals at Punta Alta, in Bahia Blanca, were still living 
species. These shells have since been examined (see ' Geological 
Observations in South America,' p. 83) by M. Alcide d'Orbigny, 
and he pronounces them all to be recent. M. Aug. Bravard has 
lately described, in a Spanish work (* Observaciones Geologicas,' 
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 forma- 
tion, like sand-dunes: this seems to me to be an untenable 
doctrine. 

At page 378 I give a list of the birds inhabiting the Galapagos 
Archipelago. The progress of research has shown that some of 
these birds, which were then thought to be confined to the islands, 
occur on the American continent. The eminent ornithologist, 
Mr. Sclater, informs me that this is the case with the Strix puncta- 
tissima and Pyrocephalus nanus ; and probably with the Otus 
galapagoensis and Zenaida galapagoensis : so that the number of 
endemic birds is reduced to twenty-three, or probably to twenty- 
one. Mr. Sclater thinks that one or two of these endemic forms 
should be ranked rather as varieties than species, which always 
seemed to me probable. 

The snake mentioned at page 381, as being, on the authority 
of M. Bibron, the same with a Chilian species, is stated by Dr. 
Gunter (Zcolog. Soc., Jan. 24th, 1859) to be a peculiar specks, 
not known to inhabit any other country.

ST. JAGO CAPE DE VERD 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 Roy, R.N., sailed from Devonport on the 
27th of December, 1831. The object of the expedition was to 
complete the survey of Patagonia and Tierra del Fuego, com- 
menced under Captain King in 1826 to 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 suddenly 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 successivf

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, 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. Tha 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 vegeta- 
tion 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 Porto 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 lagoensis), 
which tamely sits on the branches of the castor-oil plant, and 
thence darts on grasshoppers and lizards. It is brightly coloured, 
but not so beautiful as the European species : in its flight, man- 
ners, and place of habitation, 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 pro- 
duces a most refreshing margin of luxuriant vegetation. In the 
course of an hour we arrived at Ribeira Grande, and were sur- 
prised at the sight of a large ruined fort and cathedral. This 
little town, before its harbour was filled up, was the principal 

* I state this on the authority of Dr. E. Diofienhach, in his German 
translation of the first edition of this Journal.

place in the island : it now presents a melancholy, but very pic- 
turesque 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 the gover- 
nors 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 us 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, col- 
lected to watch us. Our companions were extremely merry ; 
and everything 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 we 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 

* The Cape de 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. 

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 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 yinte'ms, 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 tho air was saturated 
with moisture. The fact, however, turned out quite the con- 
trary. The hygrometer gave a difference of 29'6 degrees, 
between the temperature of the air, and the point at which dew 
was precipitated. 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 re- 
markable degree of aerial transparency with such a state of 
weather ? 

Generally the atmosphere is hazy ; and this is caused by the 
fulling 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* 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 months when the harmattan 
is known to raise clouds of dust high into the atmosphere, we 
may feel sure that it all comes from Africa. It 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 every- 
thing 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 
the land, 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 

* 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 Geolo 
.^ical Society.

some miles along tiie 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 em- 
bedded, 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 crys- 
talline 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 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 be- 
lieve, 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 dis- 
tinguished 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 branchiae or 
lungs. It feeds on the delicate sea-weeds which grow among 
the stones in muddy and shallow water ; and I found in its sto- 
mach 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 thia 
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 



1832.] HABITS OF A CUTTLE-FISH. 7 

pools of water left by the retiring tide, these animals were no* 
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 accord- 
ing 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 care- 
fully, was a French grey, with numerous minute spots of bright 
yellow: the former of these varied 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 black : a similar effect, 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.^ 

This cuttle-fish displayed its chameleon-like power both during 
the act of swimming and whilst remaining stationary at the bot- 
tom. I was much amused by the venous 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 ; some- 
times 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 cer- 
tainly 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 phosphorescent 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 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 Noronha. 
The highest point is only fifty feet above the level of the sea, and 
the entire circumference is under three-quarters of a mile. This 
small point rises abruptly out of the depths of the ocean. Its 
mineralogical constitution 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 believe, 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 multi- 
tude of seafowl, and partly to a coating of a hard glossy sub- 
stance with a pearly lustre, which is intimately united to the sur- 
face 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 stalac- 
titic branching bodies, formed apparently in the same manner as 



1832.] SINGULAR INCRUSTATIONS. 9 

the thin white coating on these rocks. The branching bodies so 
closely resembled in general appearance certain nulliporae (a 
family of hard calcareous sea-plants), that in lately looking hastily 
over my collection I did not perceive the difference. The glo- 
bular extremities of the branches are of a pearly texture, like the 
enamel of teeth, but so hard as just to scratch plate-glass. 1 
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 cryptogamic plants (Mar- 
chantiae) 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 incrusta- 
tion 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 ex- 
posed 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 comoosition of the hard parts, such as bones and 



10 ST. PAUL'S ROCKS. [CHAP. i. 

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 fresli shell, re- 
formed 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 anj 
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 suppose, had been brought by 
the male bird for its partner. It was amusing to watch how 
quickly a large and 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 W. Symonds, 
one of the few persons who have landed here, informs me 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 ter- 
restrial fauna : a fly (Olrersia) 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 suppose prey on these small 
attendants and scavengers of the waterfowl. 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 quite correct ; 
I fear it destroys the poetry of this story, that feather and dirt- 

* Mr. Homer and Sir David Brewster have described (Philosophical 
Transactions, 1836, p. 65) 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 Avith 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 
die strong tendency which carbonate of lime and animal matter evince to 
form a solid substance allied to shell.

feeding and parasitic insects and spiders should be the first in- 
habitants 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 circumstance of fish having been observed 
in the neighbourhood. 

FERNANDO NORONHA, Feb. 20th. As far as I was enabled 
to observe, during the few hours we stayed at this place, the con 
stitution 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 iso- 
lated masses, at first one is inclined to believe that it has been 
suddenly pushed up in a semi-fluid state. At St. Helena, how- 
ever, 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. The whole island is co- 
vered with wood ; but from the dryness 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. 

BAIIIA, OR SAN SALVADOR. BRAZIL, Feb. 29th. The day 
has past delightfully. Delight itself, however, is a weak term 
to express the feelings of a naturalist who, for the first time, has 
wandered by himself in a Brazilian forest. The elegance of the 
grasses, the novelty of the parasitical plants, the beauty of the 
flowers, the glossy green of the foliage, but above all the ge- 
noral luxuriance of the vegetation, filled me with admiration. 
A most paradoxical mixture of sound and silence pervades the 



12 BAHIA BRAZIL. [CHAP. i. 

shady parts of the wood. The noise from the insects is so loud, 
that it may be heard even in a vessel anchored several hundred 
yards from the shore; yet within the recesses of the forest a 
universal silence appears to reign. To a person fond of natural 
history, such a day as this brings with it a deeper pleasure than 
he can ever hope to experience again. After wandering about 
for some hours, 1 returned to the landing-place; but, before 
reaching it, I was overtaken by a tropical storm. I tried to 
find shelter under a tree, which was so thick that it would never 
have been penetrated by common English rain ; but here, in a 
couple of minutes, a little torrent flowed down the trunk. It is 
to this violence of the rain that we must attribute the verdure 
at the bottom of the thickest woods : if the showers were like 
those of a colder clime, the greater part would be absorbed or 
evaporated before it reached the ground. I will not at present 
attempt to describe the gaudy scenery of this noble bay, because, 
in our homeward voyage, we called here a second time, and I 
shall then have occasion to remark on it. 

Along the whole coast of Brazil, for a length of at least 2000 
miles, and certainly for a considerable space inland, wherever 
solid rock occurs, it belongs to a granitic formation. The cir- 
cumstance of this enormous area being constituted of materials 
which most geologists believe to have been crystallized when 
heated under pressure, gives rise to many curious reflections. 
Was this effect produced beneath the depths of a profound ocean ? 
or did a covering of strata formerly extend over it, which has 
since been removed ? Can we believe that any power, acting 
for a time short of infinity, could have denuded the granite over 
so many thousand square leagues ? 

On a point not far from the city, where a rivulet entered the 
sea, I observed a fact connected with a subject discussed by 
Hurnboldt.* At the cataracts of the great rivers Orinoco, Nile, 
and Congo, the syenitic rocks are coated by a black substance, 
appearing as if they had 'been polished with plumbago. The 
layer is of extreme thinness ; and on analysis by Berzelius it was 
found to consist of the oxides of manganese and iron. In the 
Orinoco it occurs on the rocks periodically washed by the floods, 
and in those parts alone where the stream is rapid ; or, as the 
* Pers. Narr., vol. v. pt. i. p. 18. 



1832.] HABITS OF A DIODON. 13 

Indians say, " the rocks are black where the waters are white." 
Here the coating is of a rich brown instead of a black colour, 
and seems to be composed of ferruginous matter alone. Hand 
specimens fail to give a just idea of these brown burnished 
stones which glitter in the sun's rays. They occur only within 
the limits of the tidal waves ; and as the rivulet slowly trickles 
down, the surf must supply the polishing power of the cataracts 
in the great rivers. In like manner, the rise and fall of the tide 
probably answer to the periodical inundations ; and thus the 
same effects are produced under apparently different but really 
similar circumstances. The origin, however, of these coatings 
of metallic oxides, which seem as if cemented to the rocks, is not 
understood ; and no reason, I believe, can be assigned for their 
thickness remaining the same. 

One day I was amused by watching the habits of the Diodon 
antennatus, which was caught swimming near the shore. This 
fish, with its flabby skin, is well known to possess the singular 
power of distending itself into a nearly spherical form. After 
having been taken out of water for a short time, and then again 
immersed in it, a considerable quantity both of water and air 
is absorbed by the mouth, and perhaps likewise by the branchial 
orifices. This process is effected by two methods : the air is 
swallowed, and is then forced into the cavity of the body, its 
return being prevented by a muscular contraction which is exter- 
nally visible : but the water enters in a gentle stream through 
the mouth, which is kept wide open and motionless ; this latter 
action must, therefore, depend on suction. The skin about the 
abdomen is much looser than that on the back ; hence, during 
the inflation, the lower surface becomes far more distended than 
the upper ; and the fish, in consequence, floats with its back 
downwards. Cuvier doubts whether the Diodon in this position 
is able to swim ; but not only can it thus move forward in a 
straight line, but it can turn round to either side. This latter 
movement is effected solely by the aid of the pectoral fins ; the 
tail being collapsed, and not used. From the body being buoyed 
up with so much air, the branchial openings are out of water, 
but a stream drawn in by the mouth constantly flows through 
them. 

The fish, having remained in this distended state for a short 



14 BAHIA BRAZIL. [CHAP. i. 

time, generally expelled the air and water with considerable 
force from the branchial apertures and mouth. It could emit, 
at will, a certain portion of the water ; and it appears, therefore, 
probable that this fluid is taken in partly for the sake of regu- 
lating its specific gravity. This Diodon possessed several means 
of defence. It could give a severe bite, and could eject water 
from its mouth to some distance, at the same time making a curious 
noise by the movement of its jaws. By the inflation of its body, 
the papillae, with which the skin is covered, become erect and 
pointed. But the most curious circumstance is, that it secretes 
from the skin of its belly, when handled, a most beautiful car- 
mine-red fibrous matter, which stains ivory and paper in so 
permanent a manner, that the tint is retained with all its bright- 
ness to the present day : I am quite ignorant of the nature and 
use of this secretion. I have heard from Dr. Allan of Forres, 
that he has frequently found a Diodon, floating alive and dis- 
tended, in the stomach of the shark ; and that on several occa- 
sions he has known it eat its way, not only through the coats of 
the stomach, but through the sides of the monster, which has thus 
been killed. Who would ever have imagined that a little soft 
fish could have destroyed the great and savage shark ? 

March IStk.We sailed from Bahia. A few days afterwards, 
when not far distant from the Abrolhos Islets, my attention was 
called to a reddish-brown appearance in the sea. The whole 
surface of the water, as it appeared under a weak lens, seemed as 
if covered by chopped bits of hay, with their ends jagged. These 
are minute cylindrical confervas, in bundles or rafts of from 
twenty to sixty in each. Mr. Berkeley informs me that they are 
the same species (Trichodesmium erythrasum) with that found over 
large spaces in the Red Sea, and whence its name of Red Sea is de- 
rived.* Their numbers must be infinite : the ship passed through 
several bands of them, one of which was about ten yards wide, 
and, judging from the mud-like colour of the water, at least two 
and a half miles long. In almost every long voyage some 
account is given of these confervas. They appear especially com- 
mon in the sea near Australia ; and off Cape Leeuwin I found an

allied, but smaller and apparently different species. Captain 
Cook, in his third voyage, remarks, that the sailors gave to this 
appearance the name of sea-sawdust. 

Near Keeling Atoll, in the Indian Ocean, I observed many 
little masses of confervas a few inches square, consisting of long 
cylindrical threads of excessive thinness, so as to be barely visible 
to the naked eye, mingled with other rather larger bodies, finely 
conical at both ends. Two of these 
are shown in the woodcut united 
together. They vary in length from 
04 to -06, and even to -08 of an 
inch in length ; and in diameter from -006 to '008 of a inch. 
Near one extremity of the cylindrical part, a green septum, 
formed of granular matter, and thickest in the middle, may 
generally be seen. This, I believe, is the bottom of a most deli- 
cate, colourless sac, composed of a pulpy substance, which lines 
the exterior case, but does not extend within the extreme conical 
points. In some specimens, small but perfect spheres of brownish 
granular matter supplied the places of the septa ; and I observed 
the curious process by which they were produced. The pulpy 
matter of the internal coating suddenly grouped itself into lines, 
some of which assumed a form radiating from a common centre ; 
it then continued, with an irregular and rapid movement, to 
contract itself, so that in the course of a second the whole was 
united into a perfect little sphere, which occupied the position of 
the septum at one end of the now quite hollow case. The for- 
mation of the granular sphere was hastened by any accidental 
injury. I may add, that frequently a pair of these bodies were 
attached to each other, as represented above, cone beside cone, at 
that end where the septum occurs. 

I will here add a few other observations connected with the 
discoloration of the sea from organic causes. On the coast of 
Chile, a few leagues north of Concepcion, the Beagle one day 
passed through great bands of muddy water, exactly like that of 
a swollen river ; and again, a degree south of Valparaiso, when 
fifty miles from the land, the same appearance was still more 
extensive. Some of the water placed in a glass was of a pale 
reddish tint ; and, examined under a microscope, was seen to 
swarm with minute animalcula darting about, and often explod- 



16 DISCOLOURED SEA. [CHAP. i. 

ing. Their shape is oval, and contracted in the mid lie by a 
ring of vibrating curved ciliae. It was, however, very difficult 
to examine them with care, for almost the instant motion ceased, 
even while crossing the field of vision, their bodies burst. Some- 
times both ends burst at once, sometimes only one, and a quan- 
tity of coarse, brownish, granular matter was ejected. The 
animal an instant before bursting expanded to half again its 
natural size; and the explosion took place about fifteen seconds 
after the rapid progressive motion had ceased : in a few cases it 
was preceded for a short interval by a rotatory movement on the 
longer axis. About two minutes after any number were isolated 
in a drop of water, they thus perished. The animals move with 
the narrow apex forwards, by the aid of their vibratory ciliee, 
and generally by rapid starts. They are exceedingly minute, 
and quite invisible to the naked eye, only covering a space equal 
to the square of the thousandth of an inch. Their numbers 
were infinite ; for the smallest drop of water which I could re- 
move contained very many. In one day we passed through two 
spaces of water thus stained, one of which alone must have 
extended over several square miles. What incalculable numbers 
of these microscopical animals ! The colour of the water, as 
seen at some distance, was like that of a river which has flowed 
through a red clay district ; but under the shade of the vessel's 
side it was quite as dark as chocolate. The line where the red 
and blue water joined was distinctly defined. The weather for 
some days previously had been calm, and the ocean abounded, to 
an unusual degree, with living creatures.* 

In the sea around Tierra del Fuego, and at no great distance 
from the land, I have seen narrow lines of water of a bright red 
colour, from the number of Crustacea, which somewhat resemble 
in form large prawns. The sealers call them whale-food. 
Whether whales feed on them I do not know ; but terns, cormo- 

* M. Lesson (Voyage de la Coquille, torn, i., p. 255) mentions red water 
off Lima, apparently produced by the same cause. Peron, the distinguished 
naturalist, in the Voyage aux Terres Australes, gives no less than twelve 
references to voyagers who have alluded to the discoloured waters of the sea 
(vol. ii. p. 239). To the references given by Peron may be added, Hum-

1832.] DISCOLOURED SEA. 17 

rants, and immense herds of great unwieldy seals derive, on some 
parts of the coast, their chief sustenance from these swimming 
crabs. Seamen invariably attribute the discoloration of the 
water to spawn ; but I found this to be the case only on one 
occasion. At the distance of several leagues from the Archipe- 
lago of the Galapagos, the ship sailed through three strips of 
r. dark yellowish, or mud-like water; these strips were some 
miles long, but only a few yards wide, and they were separated 
fmr\ the surronndiiior water by a sinuous yet distinct margin. 
The colour was caused by little gelatinous balls, about the fifth 
of an inch in diameter, in which numerous minute spherical 
ovules were embedded : they were of two distinct kinds, one being 
of a reddish colour and of a different shape from the other. 1 
cannot form a conjecture as to what two kinds of animals these 
belonged. Captain Colnett remarks, that this appearance is 
very common among the Galapagos Islands, and that the direc- 
tion of the bands indicates that of the currents ; in the described 
case, however, the line was caused by the wind. The only other 
appearance which I have to notice, is a thin oily coat on the 
water which displays iridescent colours I saw a considerable 
tract of the ocean thus covered ou the coast of Brazil ; the sea- 
men attributed it to the putrefying 1 carcass oi some whale, which 
probably was floating ai no great distance. I do not here men- 
tion the minute gelatinous particles, hereafter to be referred to, 
which are frequently dispersed throughout the water, for they 
are not sufficiently abundant to create any change of colour. 

There are two . circumstances in the aoove accounts which 
appear remarkable : first, how do the various bodies which form 
the bands with denned edges keep together ? In the case of the 
prawn-like crabs, their movements were as coinstantaneous as Li 
a regiment of soldiers ; but this cannot happen from any thing 
like voluntary action with the ovules, or the confervae, nor is it 
probable among the infusoria. Secondly, what causes the length 
and narrowness of the bands ? The appearance so much re- 
sembles that which may be seen in every torrent, where the stream 
uncoils into long streaks the froth collected in the eddies, that 
I must attribute the effect to a similar action either of the cur- 
rents of the air or sea. Under this supposition we must believe 
that the various organized bodies are produced in certain favour

able places, and are thence removed by the set of either wind or 
water. I confess, however, there is a very great difficnlty in 
imagining any one spot to be the birthplace of the millions of 
millions of animalcula and confervas : for whence come the 
germs at such points? the parent bodies having been distri- 
buted by the winds and waves over the immense ocean. But on 
no other hypothesis can I understand their linear grouping. I 
may add that Scoresby remarks, that green water abounding with 
pelagic animals is invariably found in a neriaiu part of the Arc- 
tic Sea.

RIO DE JANEIRO. 

April 4th to July 5th, 1 832. A few days after our arrival 1 
became acquainted with an Englishman who was going to visit 
his estate, situated, rather more than a hundred miles from the 
capital, to the northward of Cape Frio. I gladly accepted his 
kind offer of allowing me to accompany him. 

April 8th. Our party amounted to seven. The first stage 
was very interesting. The day was powerfully hot, and as we 
passed through the woods, every thing was motionless, excepting 
the large and brilliant butterflies, which lazily fluttered about. 
The view seen when crossing the hills behind Praia Grande was 
most beautiful ; the colours were intense, and the prevailing tint 
a dark blue ; the sky and the calm waters of the bay vied with 
each other in splendour. After passing through some cultivated 
country, we entered a forest, which in the grandeur of all its 
parts could not be exceeded. We arrived by midday at Itha- 
caia ; this small village is situated on a plain, and round the 
central house are the huts of the negroes. These, from their 
regular form and position, reminded me of the drawings of the 
Hottentot, habitations in Southern Africa. As the moon rose 
early, we determined to start the same evening for our sleeping- 
place at the Lagoa Marica. As it was growing dark we passed 
under one of the massive, bare, and steep hills of granite which 
are so common in this country. This spot is notorious from 
having been, for a long time, the residence of some runaway 
slaves, who, by cultivating a little ground near the top, con

trived to eke out a subsistence. At length they were discovered, 
and a party of soldiers being sent, the whole were seized with the 
exception of one old woman, who, sooner than again be led into 
slavery, dashed herself to pieces from the summit of the moun- 
tain. In a Roman matron this would have been called the noble 
love of freedom : in a poor negress it is mere brutal obstinacy. 
We continued r'ding for some hours. For the few last miles 
the road was intricate, and it passed through a desert waste of 
marshes and lagoons. The scene by the dimmed light of the 
moon was most desolate. A few fireflies flitted by us ; and the 
solitary snipe, as it rose, uttered its plaintive cry. The distant 
and sullen roar of the sea scarcely broke the stillness of the 
night. 

April 9th. We left our miserable sleeping-place before sun- 
rise. The road passed through a narrow sandy plain, lying 
between the sea and the interior salt lagoons. The number of 
beautiful fishing birds, such as egrets and cranes, and the succu- 
lent plants assuming most fantastical forms, gave to the scene an 
interest which it would not otherwise have possessed. The few 
stunted trees were loaded with parasitical plants, among which 
the beauty and delicious fragrance of some of the orchideae were 
most to be admired. As the sun rose, the day became extremely 
hot, and the reflection of the light and heat from the white sand 
was very distressing. We dined at Mandetiba ; the thermometer 
in the shade being 84. The beautiful view of the distant wooded 
hills, reflected in the perfectly calm water of an extensive lagoon, 
quite refreshed us. As the venda* here was a very good one, and 
I have the pleasant, but rare remembrance, of an excellent din- 
ner, I will be grateful and presently describe it, as the type of 
its class. These houses are often large, and are built of thick 
upright posts, with boughs interwoven, and afterwards plastered. 
They seldom have floors, and never glazed windows ; but are 
generally pretty well roofed. Universally the front part is open, 
forming a kind of verandah, in which tables and benches are 
placed. The bed-rooms join on each side, and here the passenger 
may sleep as comfortably as he can, on a wooden platform, 
covered by a thin straw mat. The venda stands in a courtyard, 
where the horses are fed. On first arriving, it was our custom

to unsaddle the horses and give them their Indian corn ; then, 
with a low bow, to ask the senhor to do us the favour to give us 
something to eat. " Any thing you choose, sir," was his usual 
answer. For the few first times, vainly I thanked providence 
for having guided us to so good a man. The conversation pro- 
ceeding, the case universally became deplorable. " Any fish 
can you do us the favour of giving?" " Oh ! no, sir." " Any 
soup ?" " No, sir." " Any bread ?" " Oh ! no, sir." " Any 
dried meat ?" " Oh ! no, sir." If we were lucky, by waiting a 
couple of hours, we obtained fowls, rice, and farinha. It not 
(infrequently happened, that we were obliged to kill, with stones, 
the poultry for our own supper. When, thoroughly exhausted 
by fatigue and hunger, we timorously hinted that we should be 
glad of our meal, the pompous, and (though true) most unsatis- 
factory answer was, " It will be ready when it is ready." If we 
had dared to remonstrate any further, we should have been told 
to proceed on our journey, as being too impertinent. The hosts 
are most ungracious and disagreeable in their manners ; their 
houses and their persons are often filthily dirty ; the want of the 
accommodation of forks, knives, and spoons is common ; and I 
am sure no cottage or hovel in England could be found in a 
state so utterly destitute of every comfort. At Campos Novos, 
however, we fared sumptuously ; having rice and fowls, biscuit, 
wine, and spirits, for dinner ; coffee in the evening, and fish with 
coffee for breakfast. All this, with good food for the horses, 
only cost 2s. 6d. per head. Yet the host of this v n da, being 
asked if he knew any thing of a whip which one of the party 
had lost, gruffly answered, " How should I know ? why did you 
not take care of it ? I suppose the dogs have eaten it." 

Leaving Mandetiba, we continued to pass through an intricate 
wilderness of lakes ; in some of which were fresh, in others salt 
water shells. Of the former kind, I found a Limnaea in great 
numbers in a lake, into which, the inhabitants assured me that 
the sea enters once a year, and sometimes oftener, and makes the 
water quite salt. I have no doubt many interesting facts, in 
relation to marine and fresh water animals, might be observed 
in this chain of lagoons, which skirt the coast of Brazil. M. 
Gay* has stated that he found in the neighbourhood of Rio, 
* Annales des Sciences Naturelles for 1833. 



RIO DE JANEIRO. [CHAP. n. 



shells of the marine genera solen and mytilus, and fresh water 
ampullarise, living together in brackish water. I also frequently 
observed in the lagoon near the Botanic Garden, where the 
water is only a little less salt than in the sea, a species of hydro- 
philus, very similar to a water-beetle common in the ditches of 
P^ngland : in the same lake the only shell belonged to a genus 
generally found in estuaries. 

Leaving the coast for a time, we again entered the forest. The 
trees were very lofty, and remarkable, compared with those of 
Europe, from the whiteness of their trunks. I see by my note- 
book, " wonderful and beautiful, flowering parasites," invariably 
struck me as the most novel object in these grand scenes. Travel- 
ling onwards we passed through tracts cf pasturage, much in- 
jured by the enormous conical ants' nests, which were nearly 
twelve feet high. They gave to the plain exactly the appear 
ance of the mud volcanos at Jorullo, as figured by Humboldt. 
We arrived at Engenhodo after it was dark, having been ten 
hours on horseback. I never ceased, during the whole journey, 
to be surprised at the amount of labour which the horses were 
capable of enduring ; they appeared also to recover from any 
injury much sooner than those of our English breed. The Vam- 
pire bat is often the cause of much trouble, by biting the horses 
on their withers. The injury is generally not so much owing to 
the loss of blood, as to the inflammation which the pressure of 
the saddle afterwards produces. The whole circumstance has 
lately been doubted in England ; I was therefore fortunate in 
being present when one (Desmodus d'orbignyi, Wat.) was actually 
caught on a horse's back. We were bivouacking late one even- 
ing near Coquimbo, in Chile, when my servant, noticing that 
one of the horses was very restive, went to see what was the 
matter, and fancying he could distinguish something, suddenly 
put his hand on the beast's withers, and secured the vampire. 
Tn the morning the spot where the bite had been inflicted was 
easily distinguished from being slightly swollen and bloody.. 
The third day afterwards we rode the horse, without any ill 
effects. 

April IZth. After three days' travelling we arrived at Socego, 
the estate of Senhor Manuel Figuireda, a relation of one of our 
party. The house was simple, and, though like a barn in form. 



1832.] ARRIVAL AT SOCEGO. 23 

was well suited to the climate. In the sitting-room gilded chairs 
and sofas were oddly contrasted with the whitewashed walls, 
thatched roof, and windows without glass. The house, together 
with the granaries, the stables, and workshops for the blacks, 
who had been taught various trades, formed a rude kind of quad- 
rangle ; in the centre of which a large pile of coffee was drying. 
These buildings stand on a little hill, overlooking the cultivated 
ground, and surrounded on every side by a wall of dark green 
luxuriant forest. The chief produce of this part of the country 
is coffee. Each tree is supposed to yield annually, on an average, 
two pounds; but some give as much as eight. Mandioca or 
cassada is likewise cultivated in great quantity. Every part of 
this plant is useful : the leaves and stalks are eaten by the horses, 
and the roots are ground into a pulp, which, when pressed dry 
and baked, forms the farinha, the principal article of sustenance 
in the Brazils. It is a curious, though well known fact, that the 
juice of this most nutritious plant is highly poisonous. A few 
years ago a cow died at this Fazenda, in consequence of having 
drunk some of it. Senhor Figuireda told me that he had planted, 
the year before, one bag of feijao or beans, and three of rice ; 
the former of which produced eighty, and the latter three hun- 
dred and twenty fold. The pasturage supports a fine stock of 
cattle, and the woods are so full of game, that a deer had been 
killed on each of the three previous days. This profusion of 
food showed itself at dinner, where, if the tables did not groan, 
the guests surely did : for each person is expected to eat of every 
dish. One day, having, as I thought, nicely calculated so that 
nothing should go away . untasted, to my utter dismay a roast 
turkey and a pig appeared in all their substantial reality. Dur- 
ing the meals, it was the employment of a man to drive out of 
the room sundry old hounds, and dozens of little black children, 
which crawled in together, at every opportunity. As long as the 
idea of slavery could be banished, there was something exceed- 
ingly fascinating in this simple and patriarchal style of living: 
it was such a perfect retirement and independence from the rest 
of the world. As soon as any stranger is seen arriving, a large 
bell is set tolling, and generally some small cannon are fired 
The event is thus announced to the rocks and woods, but to 
nothing else. One morning I walked out an hour before day-

light to admire the solemn stillness of the scene ; at last, the 
silence, was broken by the morning hymn, raised on high by the 
whole body of the blacks ; and in this manner their daily work 
is generally begun. On such fazendas as these, I have no doubt 
the slaves pass happy and contented lives. On Saturday ar,d 
Sunday they work for themselves, and in this fertile climate the 
labour of two days is sufficient to support a man and his family 
for the whole week. 

April \\th. Leaving Socego, we rode to another estate on 
the Rio Macae, which was the last patch of cultivated ground in 
that direction. The estate was two and a half miles long, and 
the owner had forgotten how many broad. Only a very small 
piece had been cleared, yet almost every acre was capable of 
yielding all the various rich productions of a tropical land. 
Considering the enormous area of Brazil, the proportion of cul- 
tivated ground can scarcely be considered as any thing, compared 
to that which is left in the state of nature : at some future age, 
how vast a population it will support ! During the second day's 
journey we found the road so shut up, that it was necessary that 
a man should go ahead with a sword to cut away the creepers. 
The forest abounded with beautiful objects ; among which the 
tree ferns, though not large, were, from their bright green 
foliage, and the elegant curvature of their fronds, most worthy 
of admiration. In the evening it rained very heavily, and 
although the thermometer stood at 65, I felt very cold. As 
soon as the rain ceased, it was curious to observe the extraordi- 
nary evaporation which commenced over the whole extent of the 
forest. At the height of a hundred feet the hills were buried in 
a dense white vapour, which rose like columns of smoke from the 
most thickly-wooded parts, and especially from the valleys. I 
observed this phenomenon on several occasions : I suppose it is 
owing to the large surface of foliage, previously heated by the 
sun's rays. 

While staying at this estate, I was very nearly being an eye- 
witness to one of those atrocious acts which can only take place 
in a slave country. Owing to a quarrel and a law-suit, the 
owner was on the ^oint of taking all the women and children 
from the male slaves, and selling them separately at the public 
auction at Rio. Interest, and not any feeling of compassioQj 



1832.] APPEARANCE OF THE FORESTS. 25 

prevented this act. Indeed, I do not believe the inhumanity of 
separating thirty families, who had lived together for many years, 
even occurred to the owner. Yet I will pledge myself, that in 
humanity and good feeling he was superior to the common run 
of men. It may be said there exists no limit to the blindness of 
interest and selfish habit. I may mention one very trifling anec- 
dote, which at the time struck me more forcibly than any story 
of cruelty. I was crossing a ferry with a negro, who was un- 
commonly stupid. In endeavouring to make him understand, I 
talked loud, and made signs, in doing which I passed my hand 
near his face. He, I suppose, thought I was in a passion, and 
was going to strike him ; for instantly, with a frightened look 
and half-shut eyes, he dropped his hands. I shall never forget 
my feelings of surprise, disgust, and shame, at seeing a great 
powerful man afraid even to ward off a blow, directed, as he 
thought, at his face. This man had been trained to a degrada- 
tion lower than the slavery of the most helpless animal. 

April ISth. In returning we spent two days at Socego, and 
I employed them in collecting insects in the forest. The greater 
number of trees, although so lofty, are not more than three or 
four feet in circumference. There are, of course, a few of much 
greater dimension. Senhor Manuel was then making a canoe 
70 feet in length from a solid trunk, which had originally been 
1 10 feet long, and of great thickness. The contrast of palm 
trees, growing amidst the common branching kinds, never fails 
to give the scene an intertropical character. Here the woods 
were ornamented by the Cabbage Palm one of the most beau- 
tiful of its family. With a stem so narrow that it might be 
clasped with the two hands, it waves its elegant head at the 
height of forty or fifty feet above the ground. The woody 
creepers, themselves covered by other creepers, were of great 
thickness : some which I measured were two feet in circumference. 
Many of the older trees presented a very curious appearance from 
the tresses of a liana hanging from their boughs, and resembling 
bundles of hay. If the eye was turned from the world of foliage 
above, to the ground beneath, it was attracted by the extreme 
elegance of the leaves of the ferns and mimosae. The latter, in 
some parts, covered the surface with a brushwood only a few inches 
high. In walking across these thick beds of mimoaes, a broad track

was marked by the change of shade, produced by the drooping oi 
theii sensitive petioles. It is easy to specify the individual objects 
of admiration in these grand scenes ; but it is not possible to give 
an adequate idea of the higher feelings of wonder, astonishment, 
and devotion, which fill and elevate the mind. 

April 19th. Leaving Socego, during the two first days, we 
retraced our steps. It was very wearisome work, as the road 
generally ran across a glaring hot sandy plain, not far from the 
coast. I noticed that each time the horse put its foot on the fine 
siliceous sand, a gentle chirping noise was produced. On the 
third day we took a different line, and passed through the gay 
little village of Madre de Deos. This is one of the principal 
lines of road in Brazil ; yet it was in so bad a state that no wheel 
vehicle, excepting the clumsy bullock-waggon, could pass along. 
In our whole journey we did not cross a single bridge built of 
stone ; and those made of logs of wood were frequently so much 
out of repair, that it was necessary to go on one side to avoid 
them. All distances are inaccurately known. The road is 
often marked by crosses, in the place of milestones, to signify 
where human blood has been spilled. On the evening of the 
23rd we arrived at Rio, having finished our pleasant little ex 
cursion. 

During the remainder of my stay at Rio, I resided in a cottage 
at Botofogo Bay. It was impossible to wish for anything more 
delightful than thus to spend some weeks in so magnificent a 
country. In England any person fond of natural history enjoys 
in his walks a great advantage, by always having something to 
attract his attention ; but in these fertile climates, teeming with 
life, the attractions are so numerous, that he is scarcely able to 
walk at all. 

The few observations which I was enabled to make were 
almost exclusively confined to the invertebrate animals. The 
existence of a division of the genus Planaria, which inhabits the 
dry land, interested me much. These animals are .of so simple a 
structure, that Cuvier has arranged them with the intestinal 
worms, though never found within the bodies of other animals. 
Numerous species inhabit both salt and fresh water ; but those to 
which I allude were found, even in the drier parts of the forest, 



1832.] PLANARLE. 27 

beneath logs of rotten wood, on which I believe they feed. Iu 
general form they resemble little slugs, but are very much nar- 
rower in proportion, and several of the species are beautifully 
coloured with longitudinal stripes. Their structure is very 
simple : near the middle of the under or crawling surface there 
are two small transverse slits, from the anterior one of which a 
tunnel-shaped and highly irritable mouth can be protruded, lor 
some time after the rest of the animal was completely dead from 
the effects of salt water or any other cause, this organ still re- 
tained its vitality. 

I found no less than twelve different species of terrestrial Pla- 
nariae in different parts of the southern hemisphere.* Some 
specimens which I obtained at Van Diemen's Land, I kept alive 
for nearly two months, feeding them on rotten wood. Having 
cut one of them transversely into two nearly equal parts, in the 
course of a fortnight both had the shape of perfect animals. I 
had, however, so divided the body, that one of the halves con- 
tained both the inferior orifices, and the other, in consequence, 
none. In the course of twenty-five days from the operation, the 
more perfect half could not have been distinguished from any 
other specimen. The other had increased much in size ; and to- 
wards its posterior end, a clear space was formed in the pa- 
renchymatous mass, in which a rudimentary cup-shaped mouth 
could clearly be distinguished ; on the under surface, however, 
no corresponding slit was yet open. If the increased heat of the 
weather, as we approached the equator, had not destroyed alJ 
the individuals, there can be no doubt that this last step would 
have completed its structure. Although so well-known an ex- 
periment, it was interesting to watch the gradual production of 
every essential organ, out of the simple extremity of another 
animal. It is extremely difficult to preserve these Planariae ; as 
soon as the cessation of life allows the ordinary laws of change 
to act, their entire bodies become soft and fluid, with a rapidity 
which I have never seen equalled. 

I first visited the forest in which these Planariae were found, 
in company with an old Portuguese priest who took me out to 
hunt with him. The sport consisted in turning into the covei

RIO DE JANEIRO. [CHAP. n. 



a few dogs, and then patiently waiting to fire at any animal 
which might appear. We were accompanied by the son of a 
neighbouring farmer a good specimen of a wild Brazilian 
youth. He was dressed in a tattered old shirt and trousers, and 
had his head uncovered : he carried an old-fashioned gun and a 
large knife. The habit of carrying the knife is universal ; and 
in traversing a thick wood it is almost necessary, on account of 
the creeping plants. The frequent occurrence of murder may 
be partly attributed to this habit. The Brazilians are so dex- 
terous with the knife, that they can throw it to some distance 
with precision, and with sufficient force to cause a fatal wound. 
I have seen a number of little boys practising this art as a game 
of play, and from their skill in hitting an upright stick, they 
promised well for more earnest attempts. My companion, the 
day before, had shot two large bearded monkeys. These ani- 
mals have prehensile tails, the extremity of which, even after 
death, can support the whole weight of the body. Oiae of them 
thus remained fast to a branch, and it was necessary to cut down 
a large tree to procure it. This was soon effected, and down 
came tree and monkey with an awful crash. Our day's sport, 
besides the monkey, was confined to sundry small green parrots 
and a few toucans. I profited, nowever, by my acquaintance 
with the Portuguese padre, for on another occasion he gave me 
a fine specimen of the Yagouaroundi cat. , 

Every one has heard of the beauty of the scenery near Boto- 
fogo. The house in which I lived was seated close beneath the 
well-known mountain of the Corcovado. It has been remarked, 
with much truth, that abruptly conical hills are characteristic of 
the formation which Humboldt designates as gneiss-granite. 
Nothing can be more striking than the effect of these huge 
rounded masses of naked rock rising out of the most luxuriant 
vegetation. 

I was often interested by watching the clouds, which, rolling 
in from seaward, formed a bank just beneath the highest point 
of the Corcovado. This mountain, like most others, when thus 
partly veiled, appeared to rise to a far prouder elevation than its 
real height of 2300 feet. Mr. Daniell has observed, in his me- 
teorological essays, that a cloud sometimes appears fixed on a 
mountain summit, while the wind continues to blow over it. 



1832.] PHOSPHORESCENT INSECTS. 29 

The same phenomenon here presented a slightly different appear- 
ance. In this case the cloud was clearly seen to curl over, and 
rapidly pass by the summit, and yet was neither diminished nor 
increased in size. The sun was setting, and a gentle southerly 
breeze, striking against the southern side of the rock, mingled 
its current with the colder air above ; and the vapour was thus 
condensed : but as the light wreaths of cloud passed over the 
ridge, and came within the influence of the warmer atmosphere 
of the northern sloping bank, they were immediately redis- 
solved. 

The climate, during the months of May and June, or the be- 
ginning of winter, was delightful. The mean temperature, from 
observations taken at nine o'clock, both morning and evening, 
was only 72". It often rained heavily, but the drying southerly 
winds soon again rendered the walks pleasant. One morning, 
in the course of six hours, 1.6 inches of rain fell. As this 
storm passed over the forests which surround the Corcovado, 
the sound produced by the drops pattering on the countless mul- 
titude of leaves was very remarkable ; it could be heard at the 
distance of a quarter of a mile, and was like the rushing of a 
great body of water. After the hotter days, it was delicious to 
sit quietly in the garden and watch the evening pass into night. 
Nature, in these climes, chooses her vocalists from more humble 
performers than in Europe. A small frog, of the genus Hyla, 
sits on a blade of grass about an inch above the surface of the 
water, and sends forth a pleasing chirp : when several are to- 
gether they sing in harmony on different notes. I had some 
difficulty in catching a specimen of this frog. The genus Hyla 
has its toes terminated by small suckers ; and I found this animal 
could crawl up a pane of glass, when placed absolutely perpen- 
dicular. Various cicadse and crickets, at the same time, keep 
up a ceaseless shrill cry, but -which,, softened by the distance, is 
not unpleasant. Every evening after dark this great concert 
commenced ; and often have I sat listening to it, until my atten- 
tion has been drawn away by some curious passing insect. 

At these times the fireflies are seen flitting about from hedge 
to hedge. On a dark night the light can be seen at about two 
hundred paces distant. It is remarkable that in all the different 
kinds of glowworms, shining elaters, and various marine animalf 



RIO DE JANEIRO. [CHAP. n. 



(such as the Crustacea, medusae, nereidse, a coralline of the genus 
Clytia, and Pyrosoma), which I have observed, the light has 
been of a well-marked green colour. All the fireflies, which I 
caught here, belonged to the Lampyridae (in which family the 
English glowworm is included), and the greater number of spe- 
cimens were of Lampyris occidental is.* I found that this insect 
emitted the most brilliant flashes when irritated : in the intervals, 
the abdominal rings were obscured. The flash was almost co- 
instantaneous in the two rings, but it was just perceptible first 
in the anterior one. The shining matter was fluid and very ad- 
hesive : little spots, where the skin had been torn, continued 
bright with a slight scintillation, whilst the uninjured parts were 
obscured. When the insect was decapitated the rings remained 
uninterruptedly bright, but not so brilliant as before : local irri- 
tation with a needle always increased the vividness of the light. 
The rings in one instance retained their luminous property nearly 
twenty-four hours after the death of the insect. From these 
facts it would appear probable, that the animal has only the 
power of concealing or extinguishing the light for short inter- 
vals, and that at other times the display is involuntary. On the 
muddy and wet gravel-walks I found the larvze of this lampyris 
in great numbers : they resembled in general form the female of 
the English glowworm. These larvae possessed but feeble 
luminous powers; very differently from their parents, on the 
slightest touch they feigned death, and ceased to shine ; nor did 
irritation excite any fresh display. I kept several of them alive 
for some time : their tails are very singular organs, for they act, 
by a well-fitted contrivance, as suckers or organs of attachment, 
and likewise as reservoirs for saliva, or some such fluid. I re- 
peatedly fed them on raw meat ; and I invariably observed, that 
every now and then the extremity of the tail was applied to the 
mouth, and a drop of fluid exuded on the meat, which was then 
in the act of being consumed. The tail, notwithstanding so 
much practice, does not seem to be able to find its way to the 
mouth ; at least the neck was always touched first, and appa- 
rently as a guide.

When we were at Bahia, an elater or beetle (Pyrophorus lu- 
minosus, Illig.) seemed the most common luminous insect. The 
light in this case was also rendered more brilliant by irritation. 
I amused myself one day by observing- the springing powers of 
this insect, which have not, as it appears to me, been properly 
described.* The elater, when placed on its back and preparing 
to spring, moved its head and thorax backwards, so that the 
pectoral spine was drawn out, and rested on the edge of its 
sheath. The same backward movement being continued, the 
spine, by the full action of the muscles, was bent like a spring ; 
and the insect at this moment rested on the extremity of its head 
and wing-cases. The effort being suddenly relaxed, the head 
and thorax flew up, and in consequence, the base of the wing- 
cases struck the supporting surface with such force, that the 
insect by the reaction was jerked upwards to the height of one 
or two inches. The projecting points of the thorax, and the 
sheath of the spine, served to steady the whole body during the 
spring. In the descriptions which I have read, sufficient stress 
does not appear to have been laid on the elasticity of the spine : 
so sudden a spring could not be the result of simple muscular 
contraction, without the aid of some mechanical contrivance. 

On several occasions I enjoyed some short but most pleasant 
excursions in the neighbouring country. One day I went to 
the Botanic Garden, where many plants, well known for their 
great utility, might be seen growing. The lea v es of the cam- 
phor, pepper, cinnamon, and clove trees were delightfully aro- 
matic ; and the bread-fruit, the jaca, and the mango, vied with 
each other in the magnificence of their foliage. The landscape 
in the neighbourhood of Bahia almost takes its character from 
the two latter trees. Before seeing them, I had no idea that 
any trees could cast so black a shade on the ground. Both oi 
them bear to the evergreen vegetation of these climates the same 
kind of relation which laurels and hollies in England do to the 
lighter green of the deciduous trees. It may be observed, that 
the houses within the tropics are surrounded by the most beau- 
tiful forms of vegetation, because many of them are at the same

32 RIO DE JANEIRO. [CHAP. n. 

time most useful to man. Who can doubt that these qualities 
are united in the banana, the cocoa-nut, the many kinds of palm, 
the orange, and the bread-fruit tree ? 

During this day I was particularly struck with a remark oi 
Humboldt's, who often alludes to " the thin vapour which, with- 
out changing the transparency of the air, renders its tints more 
harmonious, and softens its effects." This is an appearance 
which I have never observed in the temperate zones. The at- 
mosphere, seen through a short space of half or three quarters? 
of a mile, was perfectly lucid, but at a greater distance all 
colours were blended into a most beautiful haze, of a pale French 
grey, mingled with a little blue. The condition of the atmos- 
phere between the morning and about noon, when the effect 
was most evident, had undergone little change, excepting in irs 
dryness. In the interval, the difference between the dew point 
and temperature had increased from 7.5 to 17. 

On another occasion I started early and walked tr the Gavia, 
or topsail mountain. The air was delightfully cool and fra- 
grant ; and the drops of dew still glittered on the leaves of the 
large liliaceous plants, which shaded the streamlets of clear 
water. Sitting down on a block of granite, it was delightful to 
v/atch the various insects and birds as they flew past. The 
humming-bird seems particularly fond of such shady retired 
spots. Whenever I saw these little creatures buzzing round a 
flower, with their wings vibrating so rapidly as to be scarcely 
visible, I was reminded of the sphinx moths : their movements 
and habits are indeed in many respects very similar. 

Following a pathway I entered a noble forest, and from a 
height of five or six hundred feet, one of those splendid views 
was presented, which are so common on every side of Rio. At 
this elevation the landscape attains its most brilliant tint ; and 
every form, every shade, so completely surpasses in magnificence 
all that the European has ever beheld in his own country, that 
he knows not how to express his feelings. The general effect 
frequently recalled to my mind the gayest scenery of the Opera- 
house or the great theatres. I never returned from these excur 
pions empty handed. This day I found a specimen of a curious- 
fungus, called Hymenophallus. Most people know the English 
Phallus, which in autumn taints the air with its odious srncll

this, however, as the entomologist is aware, is to some of our 
beetles a delightful fragrance. So was it here ; for a Strongylus. 
attracted by the odour, alighted on the fungus as I carried ; in 
my hand. We here see in two distant countries a similar rela- 
tion between plants and insects of the same families, though tht 
species of both are different. When man is the agent in intro- 
ducing into a country a new species, this relation is often 
broken : as one instance of this I may mention, that the leaves 
of the cabbages and lettuces, which in England afford food to 
such a multitude of slugs and caterpillars, in the gardens near 
Rio are untouched. 

Difring our stay at Brazil I made a large collection of insects. 
A few general observations on the comparative importance of 
the different orders may be interesting to the English entomolo- 
gist. The large and brilliantly-coloured Lepidoptera bespeak 
the zone they inhabit, far more plainly than any other race of 
animals. I allude only to the butterflies ; for the moths, con- 
trary to what might have been expected from the rankness of the 
vegetation, certainly appeared in much fewer numbers than in 
our own temperate regions. I was much surprised at the 
habits of Papilio feronia. This butterfly is not uncommon, and 
generally frequents the orange-groves. Although a high flier, 
yet it very frequently alights on the trunks of trees. On these 
occasions its head is invariably placed downwards ; and its wings 
are expanded in a horizontal plane, instead of being folded verti- 
cally, as is commonly the case. This is the only butterfly which 
I have ever seen, that uses its legs for running. Not being 
aware of this fact, the insect, more than once, as I cautiously 
approached with my forceps, shuffled on one side just as the in- 
strument was on the point of closing, and thus escaped. But a 
far more singular fact is the power which this species possesses 
of making a noise.* Several times when a pair, probably male 

* Mr. Doubleday has lately described (before the Entomological Society, 
March 3rd, 1845) a peculiar structure in the wings of this butterfly, which 
seems to be the means of its making its noise. He says, " It is remarkable 
for having a sort of drum at the base of the fore wings, between the costal 
uervure and the subcostal. These two nervures, moreover, have a peculiar 
screw-like diaphragm or vessel in the interior." I find in Langsdorff's 
travels (in the years 1803-7, p. 74) it is said, that in the island of St. Cathe- 
rine's on the coast of Brazil, a butterfly called Februa Hoffmanseggi, makes 
a noise, when flying away, like a rattle.

and female, were chasing each other in an irregular course, 
they passed within a few yards of me ; and I distinctly heard 
a clicking noise, similar to that produced by a toothed 
wheel passing under a spring catch. The noise was conti- 
nued at short intervals, and could be distinguished at about 
twenty yards' distance : I am certain there is no error in the 
observation. 

I was disappointed in the general aspect of the Coleoptersu 
The number of minute and obscurely-coloured beetles is exceed- 
ingly great.* The cabinets of Europe can, as yet, boast only of 
the larger species from tropical climates. It is sufficient to 
disturb the composure of an entomologist's mind, to look fofVard 
to the future dimensions of a complete catalogue. The carnivorous 
beetles, or Carabidae, appear in extremely few numbers within the 
tropics : this is the more remarkable when compared to the case 
of the carnivorous quadrupeds, which are so abundant in hot 
countries. I was struck with this observation both on entering 
Brazil, and when I saw the many elegant and active forms of 
the Harpalidae re-appearing on the temperate plains of La Plata. 
Do the very numerous spiders and rapacious Hymenoptera sup- 
ply the place of the carnivorous beetles ? The carrion-feeders 
and Brachelytera are very uncommon ; on the other hand, the 
Rhyncophora and Chrysomelidae, all of which depend on the 
vegetable world for subsistence, are present in astonishing num- 
bers. I do not here refer to the number of different species, but 
to that of the individual Insects ; for on this it is that the most 
striking character in the entomology of different countries de- 
pends. The orders Orthoptera and Hemiptera are particularly 
numerous ; as likewise is the stinging division of the Hymeno- 
ptera; the bees, perhaps, being excepted. A person, on first 
entering a tropical forest, is astonished at the labours of the ants : 
well-beaten paths branch off in every direction, on which an 
army of never-failing foragers may be seen, some going forth, 

* I may mention, as a common instance of one day's (June 23rd) collect- 
ing, when I was not attending particularly to the Coleoptera, that I caught 
sixty-eight species of that order. Among these, there were only two of the 
Carabidae, four Brachelytra, fifteen Rhyncophora, and fourteen of the Chry- 
somelidse. Thirty-seven species of Arachnidse, which I brought home, wil/

and others returning, burdened with pieces of green leaf, often 
larger than their own bodies. 

A small dark-coloured ant sometimes migrates in counties* 
numbers. One day, at Bahia, my attention was drawn by ob- 
serving many spiders, cockroaches, and other insects, and some 
lizards, rushing in the greatest agitation across a bare piece oi 
ground. A little way behind, every stalk and leaf was blackened 
by a small ant. The swarm having crossed the bare space, 
divided itself, and descended an old wall. By this means many 
insects were fairly enclosed ; and the efforts which the poor little 
creatures made to extricate themselves from such a death were 
wonderful. When the ants came to the road they changed their 
course, and in narrow files reascended the wall. Having placed 
a small stone so as to intercept one of the lines, the whole body 
attacked it, and then immediately retired. Shortly afterwards 
another body came to the charge, and again having failed to 
make any impression, this line of march was entirely given up. 
By going an inch round, the file might have avoided the stone, 
and this doubtless would have happened, if it had been originally 
there : but having been attacked, the lion-hearted little warriors 
scorned the idea of yielding. 

Certain wasp-like insects, which construct in the corners of the 
verandahs clay cells for their larvae, are very numerous in the 
neighbourhood of Rio. These cells they stuff full of half-dead 
spiders and caterpillars, which they seem wonderfully to know 
how to sting to that degree as to leave them paralysed but alive, 
until their eggs are hatched ; and the larvae feed on the horrid 
mass of powerless, half-killed victims a sight which has been 
described by an enthusiastic naturalist * as curious and pleasing ! 
I was much interested one day by watching a deadly contest 
between a Pepsis and a large spider of the genus Lycosa. The 
wasp made a sudden dash at its prey, and then flew away : the 
spider was evidently wounded, for, trying to escape, it rolled down 
a little slope, but had still strength sufficient to crawl into a 
thick tuft of grass. The wasp soon returned, and seemed sur-

RIO DE JANEIRO. [CHAP, n 



prised at not immediately finding its victim. It then commenced 
as regular a hunt as ever hound did after fox ; making short 
semicircular casts, and all the time rapidly vibrating its wings 
and antennae. The spider, though well concealed, was soon dis- 
covered ; and the wasp, evidently still afraid of its adversary's 
jaws, after much manoeuvring, inflicted two stings on the under 
side of its thorax. At last, carefully examining with its antennae 
the now motionless spider, it proceeded to drag away the body. 
But I stopped both tyrant and prey.* 

The number of spiders, in proportion to other insects, is here 
compared with England very much larger; perhaps more o 
than with any other division of the articulate animals. The 
variety of species among the jumping spiders appears almost 
infinite. The genus, or rather family of Epeira, is here charac- 
terized by many singular forms ; some species have pointed coria- 
ceous shells, others enlarged and spiny tibiae. Every path in the 
forest is barricaded with the strong yellow web of a species, 
belonging to the same division with the Epeira clavipes of Fa- 
bricius, which was formerly said by Sloane to make, in the West 
Indies, webs so strong as to catch birds. A small and pretty 
kind of spider, with very long fore-legs, and which appears to 
belong to an undescribed genus, lives as a parasite on almost 
every one of these webs. I suppose" it is too insignificant to be 
noticed by the great Epeira, and is therefore allowed to prey on 
the minute insects, which, adhering to the lines, would, otherwise 
be wasted. When frightened, this little spider either feigns 
death by extending its front legs, or suddenly drops from the 
web. A large Epeira of the same division with Epeira tubercu- 
lata and conica is extremely common, especially in dry situations. 
Its web, which is generally placed among the great leaves of the 
common agave, is sometimes strengthened near the centre by a 
pair or even four zigzag ribbons, which connect two adjoining 
rays. When any large insect, as a grasshopper or wasp, is 
caught, the spider, by a dexterous movement, makes it revolve 
very rapidly, and at the same time emitting a band of threads 

Don Felix Azara (vol. i., p. 175), mentioning a hymenopterous Insect, 
probably of the same genus, says, he saw it dragging a dead spider through 
tall grass, in a straight line to its nest, which was one hundred and sixty- 
three paces distant. He adds that the wasp, in order to find the road, every 
now and then made " demi-tours d'environ trois palmes." 



1832.] SPIDERS. 37 

from its spinners, soon envelops its prey in a case like the cocoon 
of a silkworm. The spider now examines the powerless victim, 
and gives the fatal bite on the hinder part of its thorax ; then 
retreating, patiently waits till the poison has taken effect. The 
virulence of this poison may be judged of from the fact that in 
half a minute I opened the mesh, and found a large wasp quite 
lifeless. This Epeira always stands with its head downwards 
near the centre of the web. When disturbed, it acts differently 
according to circumstances : if there is a thicket below, it 
suddenly falls down ; and I have distinctly seen the thread from 
the spinners lengthened by the animal while yet stationary, as 
preparatory to its fall. If the ground is clear beneath, the Epeira 
seldom falls, but moves quickly through a central passage from 
one to the other side. When still further disturbed, it practises 
a most curious manoeuvre : standing in the middle, it violently 
jerks the w<;b, which is attached to elastic twigs, till at last the 
whole acquires such a rapid vibratory movement, that even the 
outline of the spider's body becomes indistinct. 

It is well known that most of the British spiders, when a large 
insect is caught in their webs, endeavour to cut the lines and 
liberate their prey, to save their nets from being entirely spoiled. 
I once, however, saw in a hot-house in Shropshire a large female 
wasp caught in the irregular web of a quite small spider; and 
this spider, instead of cutting the web, most perseveringly con- 
tinued to entangle the body, and especially the wings, of its 
prey. The wasp at first aimed in vain repeated thrusts with 
its sting at its little antagonist. Pitying the wasp, after allow- 
ing it to struggle for more than an hour, I killed it and put 
it back into the web. The spider soon returned ; and an 
hour afterwards I was much surprised to find it with its jaws 
buried in the orifice, through which the sting is protruded by 
the living wasp. I drove the spider away two or three times, 
but for the next twenty-four hours I always found it again 
sucking at the same place. The spider became much distended 
by the juices of its prey, which was many times larger than 
itself. 

I may here just mention, that I found, near St. Fe Bajada, 
many large black spiders, with ruby coloured marks on their 
backs, having gregarious habits. The webs were placed verti- 



38 RIO DE JANEIRO. [CRAP. n. 

cally, as is invariably the case with the genus Epeira : they were 
separated from each other by a space of about two feet, but were 
all attached to certain common lines, which were of great length, 
and extended to all parts of the community. In this manner the 
tops of some large bushes were encompassed by the united nets. 
Azara* has described a gregarious spider in Paraguay, which 
Walckenaer thinks must be a Theridion, but probably it is an 
Epeira, and perhaps even the same species with mine. I cannot, 
however, recollect seeing a central nest as large as a hat, in 
which, during autumn, when the spiders die, Azara says the eggs 
are deposited. As all the spiders which I saw were of the same 
size, they must have been nearly of the same age. This gre- 
garious habit, in so typical a genus as Epeira, among insects, 
which are so bloodthirsty and solitary that even the two sexes at- 
tack each other, is a very singular fact. 

In a lofty valley of the Cordillera, near Mendoza, I found 
another spider with a singularly-formed web. Strong lines 
radiated in a vertical plane from a common centre, where the 
insect had its station ; but only two of the rays were connected 
by a symmetrical mesh-work ; so that the net, instead of being, at 
is generally the case, circular, consisted of a wedge-shaped seg- 
ment. All the webs were similarly constructed.

MALDONADO. 

July 5th, 1832. IN the morning we got under way, and 
stood out of the splendid harbour of Rio de Janeiro. In our 
passage to the Plata, we saw nothing particular, excepting on 
one day a great shoal of porpoises, many hundreds in number. 
The whole sea was in places furrowed by them ; and a most 
extraordinary spectacle was presented, as hundreds, proceeding 
together by jumps, in which their whole bodies were exposed, 
thus cut the water. When the ship was running nine knots an 
hour, these animals could cross and recross the bows with the 
greatest ease, and then dash away right ahead. As soon as we 
entered the estuary of the Plata, the weather was very unsettled. 
One dark night we were surrounded by numerous seals and 
penguins, which made such strange noises, that the officer on 
watch reported he could hear the cattle bellowing on shore. 
On a second night we witnessed a splendid scene of natural fire- 
works; the mast-head and yard-arm-ends shone with St. Elmo's 
light ; and the form of the vane could almost be traced, as if it 
had been rubbed with phosphorus. The sea was so highly lumi- 
nous, that the tracks of the penguins were marked by a fiery 
wake, and the darkness of the sky was momentarily illuminated 
by the most vivid lightning. 

When within the mouth of the river, I was interested by ob- 
serving how slowly the waters of the sea and river mixed. The 
latter, muddy and discoloured, from its less specific gravity, 
floated on the surface of the salt water. This was curiously 
exhibited in the wake of the vessel, where a line of blue watej 
was seen mingling in little eddies, with the adjoining fluid.

40 MALDONADO. [CHAP. in. 

July 2Qth. We anchored at Monte Video. The Beagle was 
employed in surveying the extreme southern and eastern coasts 
of America, south of the Plata, during the two succeeding years. 
To prevent useless repetitions, I will extract those parts of my 
journal which refer to the same districts, without always attend- 
ing to the order in which we visited them. 

MALDONADO is situated on the northern bank of the Plata, 
and not very far from the mouth of the estuary. It is a most 
quiet, forlorn, little town ; built, as is universally the case in 
these countries, with the streets running at right angles to each 
other, and having in the middle a large plaza or square, which, 
from its size, renders the scantiness of the population more evi- 
dent. It possesses scarcely any trade ; the exports being con- 
fined to a few hides and living cattle. The inhabitants are chiefly 
landowners, together with a few shopkeepers and the neces- 
sary tradesmen, such as blacksmiths and carpenters, who do nearly 
all the business for a circuit of fifty miles round. The town is 
separated from the river by a band of sand-hillocks, about a mile 
broad : it is surrounded, on all other sides, by an open slightly- 
undulating country, covered by one uniform layer of fine green 
turf, on which countless herds of cattle, sheep, and horses graze. 
There is very little land cultivated even close to the town. A 
few hedges, made of cacti and agave, mark out where some wheat 
or Indian corn has been planted. The features of the country 
are very similar along the whole northern bank of the Plata. 
The only difference is, that here the granitic hills are a little 
bolder. The scenery is very uninteresting ; there is scarcely a 
house, an enclosed piece of ground, or even a tree, to give it an 
air of cheerfulness. Yet, after being imprisoned for some time 
in a ship, there is a charm in the unconfined feeling of walking 
over boundless plains of turf. Moreover, if your view is limited 
to a small space, many objects possess beauty. Some of the 
smaller birds are brilliantly coloured ; and the bright green 
sward, browsed short by the cattle, is ornamented by dwarf 
flowers, among which a plant, looking like the daisy, claimed 
the place of an old friend. What would a florist say to whole 
tracts so thickly covered by the Verbena melindres, as, even at a 
distance, to appear of the most gaudy scarlet ? 

T staid ten weeks at Maldonado, in which time a nearly perfect

collection of the animals, birds, and reptiles, was procured. 
Before making 1 any observations respecting them, I will give an 
account of a little excursion I made as far as the river Polanco, 
which is about seventy miles distant, in a northerly direction. 
I may mention, as a proof how cheap everything is in this 
country, that I paid only two dollars a day, or eight shillings, 
for two men, together with a troop of about a dozen riding- 
horses. My companions were well armed with pistols and 
sabres ; a precaution which I thought rather unnecessary ; but 
the first piece of news we heard was, that, the day before, a tra- 
veller from Monte Video had been found dead on the road, with 
his throat cut. This happened close 1o a cross, the record of a 
former murder. 

On the first night we slept at a retired little country-house ; 
nd there I soon found out that I possessed two or three articles, 
especially a pocket compass, which created unbounded astonish- 
ment. In every house I was asked to show the compass, and by 
its aid, together with a map, to point out the direction of various 
places. It excited the liveliest admiration that I, a perfect 
stranger, should know the road (for direction and road are syno- 
nymous in this open country) to places where I had never been. 
At one house a young woman, who was ill in bed, sent to entreat 
me to come and show her the compass. If their surprise was 
great, mine was greater, to find such ignorance among people 
who possessed their thousands of cattle, and " estancias " of great 
extent. It can only be accounted for by the circumstance that 
this retired part of the country is seldom visited by foreigners. 
I was asked whether the earth or sun moved ; whether it \cas 
hotter or colder to the north ; where Spain was, and many other 
such questions. The greater number of the inhabitants had an 
indistinct idea that England, London, and North America, were 
different names for the same place ; but the better informed well 
knew that London and North America were separate countries 
^lose together, and that England was a large town in London ! 
I carried with me some promethean matches, which I ignited by 
biting ; it was thought so wonderful that a man should strike 
fire with his teeth, that it was usual to collect the whole family 
to see it : I was once offered a dollar for a single one. Washing 
tny face in the morning caused much speculation at the village 



42 MALDONADO. [CHAP. in. 

of Las Minas ; a superior tradesman closely cross- questioned me 
about so singular a practice ; and likewise why on board we 
wore our beards ; for he had heard from my guide that we did 
so. He eyed me with much suspicion ; perhaps he had heard of 
ablutions in the Mahomedan religion, and knowing me to be a 
heretick, probably he came to the conclusion that all hereticks 
were Turks. It is the general custom in this country to ask for 
a night's lodging at the first convenient house. The astonish- 
ment at the compass, and my other feats in jugglery, was to a 
certain degree advantageous, as with that, and the long stories 
my guides told of my breaking stones, knowing venomous from 
harmless snakes, collecting insects, &c., I repaid them for their 
hospitality. I am writing as if I had been among the inhabit- 
ants of central Africa : Banda Oriental would not be flattered 
by the comparison ; but such were my feelings at the time. 

The next day we rode to the village of Las Minas. The 
country was rather more hilly, but otherwise continued the same ; 
an inhabitant of the Pampas no doubt would have considered it 
as truly Alpine. The country is so thinly inhabited, that 
during the whole day we scarcely met a single person. Las Minas 
is much smaller even than Maldonado. It is seated on a little 
plain, and is surrounded by low rocky mountains. It is of the 
usual symmetrical form ; and with its whitewashed church 
standing in the centre, had rather a pretty appearance. The 
outskirting houses rose out of the plain like isolated beings, 
without the accompaniment of gardens or courtyards. This is 
generally the case in the country, and all the houses have, in 
consequence, an uncomfortable aspect. At night we stopped at 
a pulprria, or drinking-shop. During the evening a great num- 
ber of Gauchos came in to drink spirits and smoke cigars : their 
appearance is very striking ; they are generally tall and hand- 
some, but with a proud and dissolute expression of countenance. 
They frequently wear their moustaches, and long black hair 
curling down their backs. With their brightly-coloured gar- 
ments, great spurs clanking about their heels, and knives stuck 
as daggers (and often so used) at their waists, they look a very 
different race of men from what might be expected from their 
name of Gauchos, or simple countrymen. Their politeness is 
excessive ; they never drink their spirits without expecting you 



1832.] POINTS OF ETIQUETTE. 43 

to taste it ; but M hilst making their exceedingly graceful bow, 
they seem quite as ready, if occasion offered, to cut your throat. 

On the third day we pursued rather an irregular course, as 1 
was employed in examining some beds of marble. On the fine 
plains of turf we saw many ostriches (Struthio rhea). Some of the 
flocks contained as many as twenty or thirty birds. These, when 
standing on any little eminence, and seen against the clear &ky, 
presented a very noble appearance. I never met with such tame 
ostriches in any other part of the country : it was easy to gallop 
np within a short distance of them ; but then, expanding their 
wings, they made all sail right before the wind, and soon left the 
horse astern. 

At night we came to the house of Don Juan Fuentes, a rich 
landed proprietor, but not personally known to either of my 
companions. On approaching the house of a stranger, it is 
usual to follow several little points of etiquette : riding up slowly 
to the door, the salutation of Ave Maria is given, and until 
somebody comes out and asks you to alight, it is not customary 
even to get off your horse : the formal answer of the owner is, 
" sin pecado concebida " that is, conceived without sin. Having 
entered the house, some general conversation is kept up for a 
few minutes, till permission is asked to pass the night there. 
This is granted as a matter of course. The stranger then takes 
his meals with the family, and a room is assigned him, where 
with the horsecloths belonging to his recado (or saddle of the 
Pampas) he makes his bed. It is curious how similar circum- 
stances produce such similar results in manners. At the Cape 
of Good Hope the same hospitality, and very nearly the same 
points of etiquette, are universally observed. The difference, 
however, between the character of the Spaniard and that of the 
Dutch boor is shown, by the former never asking his guest a 
single question beyond the strictest rule of politeness } whilst the 
honest Dutchman demands where he has been, where he is going, 
what is his business, and even how many brothers, sisters, or 
children he may happen to have. 

Shortly after our arrival at Don Juan's, one of the large herds 
of cattle was driven in towards the house, and three beasts were 
picked out to be slaughtered for the supply of the establishment. 
These half-wild cattle are very active ; and knowing full well 



44 MALDONADO. [CHAP. in. 

the fatal lazo, they *ed the horses a long and laborious chase. 
After witnessing the rude wealth displayed in the number of 
cattle, men, and horses, Don Juan's miserable house was quite 
curious. The floor consisted of hardened mud, and the windows 
were without glass ; the sitting-room boasted only of a few of 
the roughest chairs and stools, with a couple of tables. The 
supper, although several strangers were present, consisted of two 
huge piles, one of roast beef, the other of boiled, with some 
pieces of pumpkin : besides this latter there was no other vege- 
table, and not even a morsel of bread. For drinking, a large 
earthenware jug of water served the whole party. Yet this man 
was the owner of several square miles of land, of which nearly 
every acre would produce corn, and, with a little trouble, all the 
common vegetables. The evening was spent in smoking, with a 
little impromptu singing, accompanied by the guitar. The sig- 
noritas all sat together in one corner of the room, and did not 
sup with the men. 

So many works have been written about these countries, that 
it is almost superfluous to describe either the lazo or the bolas. 
The lazo consists of a very strong, but thin, well-plaited rope, 
made of raw hide. One end is attached to the broad surcingle, 
which fastens together the complicated gear of the recado, or 
saddle used in the Pampas ; the other is terminated by a small 
ring of iron or brass, by which a noose can be formed. The 
Gaucho, when he is going to use the lazo, keeps a small coil in 
his bridle-hand, and in the other holds the running noose, which 
is made very large, generally having a diameter of about eight 
feet. This he whirls round his head, and by the dexterous move- 
ment of his wrist keeps the noose open ; then, throwing it, he 
causes it to fall on any particular spot he chooses. The lazo, 
when not used, is tied up in a small coil to the after part of the 
recado. The bolas, or balls, are of two kinds : the simplest, 
which is chiefly used for catching ostriches, consists of two 
round stones, covered with leather, and united by a thin plaited 
thong, about eight feet long. The other kind differs only in 
having three balls united by the thongs to a common centre. 
The Gaucho holds the smallest of the three in his hand, and 
whirls the other two round and round his head ; then, taking 
aim, sends them like chain shot revolving through the air. The 



1832.] THROWING THE BOLAS. 45 

balls no sooner strike any object, than, winding round it, they 
cross each other, and become firmly hitched. The size and 
weight of the balls varies, according to the purpose for which 
they are made: when of stone, although not larger than au 
apple, they are sent with such force as sometimes to break the 
leg even of a horse. I have seen the balls made of wood, and as 
large as a turnip, for the sake of catching these animals without 
injuring them. The balls are sometimes made of iron, and these 
can be hurled to the greatest distance. The main difficulty in 
using either lazo or bolas is to ride so well as to be able at full 
speed, and while suddenly turning about, to whirl them so 
steadily round the head, as to take aim : on foot any person 
would soon learn the art. One day, as I was amusing myself 
by galloping and whirling the balls round my head, by accident 
the free one struck a bush ; and its revolving motion being thus 
destroyed, it immediately fell to the ground, and like magic 
caught one hind leg of my horse ; the other ball was then jerked 
out of my hand, and the horse fairly secured. Luckily he was 
an old practised animal, and knew what it meant ; otherwise he 
would probably have kicked till he had thrown himself down. 
The Gauchos roared with laughter ; they cried out that they 
had seen every sort of animal caught, but had never before seen 
a man caught by himself. 

During the two succeeding days, I reached the furthest point 
which I was anxious to examine. The country wore the same 
aspect, till at last the fine green turf became more wearisome 
than a dusty turnpike road. We everywhere saw great numbers 
of partridges (Nothura major). These birds do not go in coveys, 
nor do they conceal themselves like the English kind. It appears 
a very silly bird. A man on horseback by riding round and 
round in a circle, or rather in a spire, so as to approach closer 
each time, may knock on the head as many as he pleases. The 
rrore common method is to catch them with a running noose, or 
little lazo, made of the stem of an ostrich's feather, fastened to 
the end of a long stick. A boy on a quiet old horse will fre- 
quently thus catch thirty or forty in a day. In Arctic North 
America* the Indians catch the Varying Hare by walking spirally

round and round it, when on its form : the middle of the day 
is reckoned the best time, when the sun is high, and the shadow 
of the hunter not very long. 

On our return to Maldonado, we followed rather a different 
line of road. Near Pan de Azucar, a landmark well known to 
all those who have sailed up the Plata, I stayed a day at the 
house of a most hospitable old Spaniard. Early in the morning' 
we ascended the Sierra de las Animas. By the aid of the rising 
sun the scenery was almost picturesque. To the westward the 
view extended over an immense level plain as far as the Mount, 
at Monte Video, and to the eastward, over the mamrnillaled 
country of Maldonado. On the summit of the mountain there 
were several small heaps of stones, which evidently had lain there 
for many years. My companion assured me that they were the 
work of the Indians in the old time. The heaps were similar, 
but on a much smaller scale, to those so commonly found on the 
mountains of Wales. The desire to signalize any event, on the 
highest point of the neighbouring land, seems an universal pas- 
sion with mankind. At the present day, not a single Indian, 
either civilized or wild, exists in this part of the province ; nor 
am I aware that the former inhabitants have left behind them 
any more permanent records than these insignificant piles on the 
summit of the Sierra de las Animas. 

The general, and almost entire absence of trees in Banda 
Oriental is remarkable. Some of the rocky hills are partly co- 
vered by thickets, and on the banks of the larger streams, espe- 
cially to the north of Las Minas, willow-trees are not uncommon. 
Near the Arroyo Tapes I heard of a wood of palms ; and one of 
these trees, of considerable size, I saw near the Pan de Azucar, 
in lat. 35. These, and the trees planted by the Spaniards, 
offer the only exceptions to the general scarcity of wood. Among 
the introduced kinds may be enumerated poplars, olives, peach, 
and other fruit trees: the peaches succeed so well, that they 
afford the main supply of firewood to the city of Buenos Ayres. 
Extremely level countries, such as the Pampas, seldom appear 
favourable to the growth of trees. This may possibly be attri- 
buted either to the force of the winds, or the kind of drainage. 
In the nature of the land, however, around Maldonado, no such 



1832.] CLIMATE AND VEGETATION. 47 

reason is apparent ; the rocky mountains afford protected situa- 
tions, enjoying various kinds of soil ; streamlets of water are 
common at the bottoms of nearly every valley ; and the clayey 
nature of the earth seems adapted to retain moisture. It has 
been inferred with much probability, that the presence of wood- 
land is generally determined* by the annual amount of moisture ; 
yet in this province abundant and heavy rain falls during the 
winter ; and the summer, though dry, is not so in any excessive 
degree.! We see n?arly the whole of Australia covered by 
lofty trees, yet that country possesses a far more arid climate. 
Hence we must look to some other and unknown cause. 

Confining our view to South America, we should certainly be 
tempted to believe that trees flourished only under a very humid 
climate ; for the limit of the forest-land follows, in a most re- 
markable manner, . that of the damp winds. In the southern 
part of the continent, where the western gales, charged with 
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 unpenetrable forests. On the 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 continent, 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. 32 S., may be described as a desert : on this western 
coast, northward of lat. 4 S., where the trade-wind loses its 
regularity, and heavy torrents of rain fall periodically, the shores 
of the Pacific, so utterly desert in Peru, assume near Cape Blanco 
tho character of luxuriance so celebrated at Guyaquil and Pa- 
nama. Hence in the southern and northern parts of the con- 
tinent, the forest and desert lands occupy reversed positions with 
respect to the Cordillera, and these positions are apparently de- 
termined 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 arid 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 impos- 
sible 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 favourable 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 (.ra.ifplant them have failed. 

Duruig our stay at Maldonado I collected several quadru- 
peds, 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, through- 
out the countries bordering the Plata and in Northern Pata- 
gonia. 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 exceed- 
ingly 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 



1832-3.] THE CAPYBARA OR WATER-HOG. 49 

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, ia the ovcr- 
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 months, when first unfolded, I distinctly perceived 
the odour. This appears an astonishing instance of the perma- 
nence of some matter, which nevertheless in its nature must 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 fw"h-eating birds in the same 
manner. 

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 tnree 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 

* 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. Water- 
house 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.

of fresh-water lakes and rivers. Near Malcloriado three or 
four generally live together. In the daytime they either lie 
among the aquatic plants, or openly feed on the turf plain.* 
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 lame ; by cautiously walk- 
ing, I approached within three yards of four old ones. This 
lameness may probably be 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 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 Rio Parana they are 
exceedingly abundant, and aiford the ordinary prey to the 
Jaguar. 

The Tucutuco (Ctenomys Brasiliensis) is a C'irious 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

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 oesophagus 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 yn. which it feeds. 



1832-3.] THE TUCUTTJCO. 61 

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 fet- 
locks. The tucutucos appear, to a certain degree, to be grega- 
rious : 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 much surprised ; for it is not 
easy to tell whence it comes, 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 repealed about four 
times in quick succession : * the name Tucutuco is given in imi- 
tation 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. 

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. Reid considers it to be the effect of inflam- 
mation 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 

* At the R. Negro, in Northern Patagonia, there 5s 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 Maldonado 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 
tie* with an axe, that I have sometimes remained in doubt concerning it. 



52 MALDONADO. [CHAP. ni. 

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 gradual \y-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 rudimentary 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 with- 
out 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 undulat 
ing 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. Seve- 
ral 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 uubbles of air passing 
rapidly from a small orifice under water, so as to produce an 
acute sound. According 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 (Zonotrichia 
matutina), with one egg in it 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 

Philosoph. Zoolog., torn. i. p. 249 



1832-3.] HABITS OF THE CUCKOO. 63 

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 
cuckoos 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 propa- 
gation, 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 caterpillars. In structure also 
these two genera are widely removed from each other. Many 
theories, even phrenological theories, have been advanced to ex- 
plain the origin of the cuckoo laying its eggs in other birds' 
nests. M. Prevost alone, 1 think, has thrown light by his obser- 
vations 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 
egg. Now, if the cuckoo was obliged to sit on her own eggs, 
she would either have to c-it 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 th's 
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 her eggs at intervals, the cause of her depositing her 
eggs in other birds' nests, and leaving them to the care of fostcr-

parents. I am strongly inclined to believe that this view is cor- 
rect, 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 under- 
taking 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 Rapacious 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 unfrequently kept either in cages or in courtyards, 
with their wings 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 undulatory, for the weight of the head and bill appear 
too great for the body. In the evening the Saurophagus takes 
its stand on a bush, often by the road-side, 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 thut of the Sedge warbler, but is more powerful ; some harsh 
notes and some very high ones, being mingled with a pleasant 



1832-3.] CARRION HAWKS. 65 

warbling. It is heard only during the spring. At other times 
its cry is harsh and far from harmonious. Near Maldonado 
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 un- 
inhabited plains of Patagonia another closely allied species, 
O. Patagoriica 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 dis- 
tinct; 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 strik- 
ing to any one accustomed only to the birds of Northern Europe. 
In this list may be included four species of the Caracara or Poly- 
borus, 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 Pata- 
gonia. In the desert between the rivers Negro and Colorado, 
numbers constantly attend the line of road to devour the car- 
casses 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 
ts nevertheless found inhabiting the damp impervious forests of 
West Patagonia and Tierra del Fuego. The Carranchas, 



MALDONADO. [CHAP. in. 



together with the Chimango, constantly attend in numbers the 
estancias and slaughtering-houses. If an animal dies on the plain 
the Gallinazo commences the feast, and then the two species of 
Folyborus pick the bones clean. These birds, although thus 
commonly 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 bottom 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, togethe** with the Chi- 
mango, 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 accuracy. These false eagles most rarely 
kill any living bird or animal ; and their vulture-like, necropha- 
gous habits are very evident 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 watch- 
ing him with an evil eye : it is a feature in the landscape of 
these countries, which will be recognised by every one who has 
wandered over them. If a party of men go out hunting with 
dogs and horses, they will be accompanied, 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 Carran- 
cha 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 utter- 



1832-3.] CARRION HAWKS. 57 

:ng 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, grasshoppers, and frogs ; that it destroys 
young lambs by tearing the umbilical cord ; and that it pursues 
the Gallinazo, till that bird is compelled to vomit up the carrion 
it may have recently gorged. Lastly, Azara states that several 
Carranchas, five or six together, will unite in chace 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 Novae Zelandiae, 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 Ramirez rocks 
their whole sustenance must depend on the sea. They are extra- 
ordinarily 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 pro- 
truded, 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 had difficulty in preventing the wounded 
geese from being seized before their eyes. It is said that several 



68 MALDONADO. [CHAP. m. 

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 harbour ; 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 any thing from the 
ground ; a large black glazed hat was carried nearly a mile, as 
was a pair of the heavy balls used m catching cattle. Mr. 
Usborne experienced during the survey a more severe loss, in 
their stealing a small Kater's compass in a red morocco leather 
case, which was never recovered. These birds are, 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 
English rook ; hence the sealers always call them rooks. It is 
a curious circumstance that, when crying out, they throw their 
heads upwards 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 the 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 the Polyborus 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 bo 
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 the carcasses of dead seals. Wherever these animals 
ire congregated on the rocks, there the 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 Monte Video, but that they 
subsequently followed the inhabitants from more northern dis- 
tricts. 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 ha.i 
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 scaven- 
gers. 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 wheel- 
ing 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 matri- 
monial 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 Laguna 
del Potrero from the shores of the Plata, at the distance of a few 
miles from Maldonado, I found a group of those vitrified, silice- 
ous tubes, which are formed by lightning entering loose sand. 
These tubes resemble in every particular those from Drigg in 
Cumberland, described in the Geological Transactions.* The 
sand-hillocks of Maldonado, not being protected by vegetation, 
are constantly changing their position. From this cause the 

* 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. 



MALDONADO. [CHAP. in. 



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 
,ve must suppose that originally it extended to a much greater 
Jepth. 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 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 : J could not distinguish any 
signs of crystallization. In a similar manner to that described 
in the Geological Transactions, the tubes are generally com- 
pressed, 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 surround- 
ing 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 mea- 
sure 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 oi 
galvanism through finely-powdered glass : when salt was added, 
so as to increase its fusibility, the tubes were larger in every

1832-3.] ELECTRIC PHENOMENA. 61 

dimension. They failed both with powdered felspar and quartz. 
One tube, formed with potmded 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 fusi- 
bility as glass was to form tubes so diminu+ive, 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 extraordinarily 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 con- 
siderable 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 be- 
neath the surface, there were several other groups of frag- 
ments, 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-hillocks, and at the dis- 
tance of about half a mile from a chain of hills four or five 
hundred feet in height. The most remarkable circumstance, as 
it appears to me, in this case as well as in that of Drigg, and in 
one described by M. Ribbentrop 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 rnosl

destructive thunderstorms perhaps on record happened at Buenos 
Ayres : thirty-seven places within the city were struck by light- 
ning, 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 pos- 
sible 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 thft 
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.

RIO NEGRO TO BAHIA BLANCA. 

July 24th, 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 j^ears 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 re- 
markable from being composed of a firmly-cemented conglome- 
rate of pumice pebbles, which must have travelled more than 
four hundred miles, from the Andes. The surface is every- 
where 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 strangei 
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 north- 
ern boundary of the great valley, in which the Rio Negro flows. 
On the way we passed the ruins of some fine " estancias," which 
a few years since had been destroyed by the Indians. They witfc^

stood se\eral attacks. A man present at one gave me a very 
lively description of what took place. The inhabitants had suffi 
cient 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 dis- 
mounted, and taken off their fur mantles, they advanced naked to 
the charge. The only weapon of an Indian is a very long bam- 
boo 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 toge- 
ther by iron nails instead of leather thongs, and, of couAe, in 
vain attempted to cut them with their knives. This saved the 
lives of the Christians : many of the wounded Indians were car- 
ried away by their companions ; and at last one of the under 
caciques being wounded, the bugle sounded a retreat. They re- 
tired 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 ap- 
proached close, and then raked their line with grape-shot : he 
thus laid thirty-nine of them on the ground ; and, of course, such 
a friow 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 in 
about two or three hundred yards wide, and is deep and rapid.

seen one behind the other on the northern boundary of the broad 
green 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 themselves the elements of growth. Many Indians 
of pure blood reside here : the tribe of the Cacique Lucanee con- 
stantly have their Toldos * on the outskirts of the town. The 
local government partly supplies them with provisions, by gi ing 
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 counter- 
balanced 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 admirable ; 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 field 
of snow-white salt. The layer near the margin is from four to 
five inches thick, but towards the centre i'.s 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 ex- 
panses, in the midst of the brown and desolate plain, offers an 
extraordinary spectacle. A large quantity of salt is annually 
drawn from the salina ; and great piles, some hundred tons in 
weight, were lying ready for exportation. The season for work- 
ing 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 crystal-

hzed in great cubes, and is remarkably pure : Mr. Trenham Reeks 
has kindly analyzed some for me, and he finds in it only 0'26 of 
gypsum and 0'22 of earthy matter. It is a singular fact, that it 
does not serve so well for preserving meat as sea-salt from the 
Cape de 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 bv 
the fact lately ascertained,* that those salts answer best for pre- 
serving cheese which contain most of the deliquescent chlorides. 
The border of the lake is formed of mud : and in this nume- 
rous 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 confervae : 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 animalcula. 
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 ; through- 
out Patagonia, in Northern Chile, and at the Galapagos Islands, 
I met with these birds wherever there were lakes f 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 confervge. Thus \ve have a little living world 
within itself, adapted to these inland lakes of brine. A minute 
crustaceous animal (Cancer salinus) is said * to live in countless 
numbers in the brine-pans at Lymington ; 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 Rio Negro, between it and the inha- 
bited country near Buenos Ayres, the Spaniards have only one 
small settlement, recently established at I>ahia Blanca. The dis- 
tance in a straight line to Buenos Ayres is very nearly five hun- 
dred 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 estancias, the govern- 
ment 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 Co- 
lorado ; a river lying about eighty miles northward of the Rio 
Negro. When General Rosas left Buen'os 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 
ntervals, a small party of soldiers with a troop of horses 
( postd), so as to be enabled to keep up a communication with 



* Linnacan Trans., vol. xi. p. 205. It is remarkable how all the circum- 
stance's connected with the salt-lakes in Siberia and Patagonia are similar. 
Siberia, like Patagonia, appears to have been recently elevated above the 
waters of the sea. In both countries the salt-lakes occupy shallow depres- 
sions in the plains ; in both the mud on the borders is black and fetid ; be- 
neath the crust of common salt, sulphate of soda or of magnesia occurs, hn- 
perfectly crystallized ; and in both, the muddy sand is mixed with lentils of 
gypsum. The Siberian salt-lakes are inhabited by small crustaceous ani- 
mals ; and flamingoes (Edin. New Philos. Jour., Jan. 1830) likewise frequent 
them. As these circumstances, apparently so trifling, occur in two distanl 
continents, we may feel sure that they are the necessary results of conunoa 
sauses. See Pallas' s Travis. 1793 to 1794, pp. 129-134. 



68 R. NEGRO TO R. COLORADO. [CHAP. iv. 

the capital. As the Beagle intended to call at Bahia Blanca, 
[ determined to proceed there by land; and ultimately I ex- 
tended my plan to travel the whole way by the postas to Buenos 
Ay res. 

August llth. Mr. Harris, an Englishman residing at Pata- 
gones, a guide, and five Gauchos, who were proceeding to the 
army on business, were my companions on the journey. The 
Colorado, as I 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 Rio Negro, broad as it is, has merely been ex- 
cavated 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 depres- 
sions. 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 Wal- 
leechu. 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 corne 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, &c. 
had been suspended. Poor Indians, not having anything better, 
only pull a thread out of their ponchos, and fasten it to the 
tree. Richer Indians are accustomed to pour spirits and 
raatt* into a certain hole, and likewise to smoke upwards, 
thinking thus to afford all possible gratification to Walleechu. 
To complete the scene, the tree was surrounded by the bleached 



183S.] SACRED TREE. 



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 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 Rio 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 chace, 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 fire- 
wood. 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. 
7"his aniraal here represents our hares. It differs, however, from 



70 RIO COLORADO. [CHAP. IT. 

that genus in many essential respects ; for instance, it has only 
three toes behind. It is also nearly twice the size, weighing 
from twenty to twenty-five pounds. The Agouti is a true friend 
of the 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. 37 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 have altered, in 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 tne 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 in- 
crusted 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 sur- 
prising : 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, 
&c. 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. 1 know not the reason, 
but men of such origin seldom have a good expression of coun- 
tenance. 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 Pata- 
gones. This was taken to General Rosas, who sent me a very 
obliging message ; and the Secretary returned all smiles and gra- 
ciousness. 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 came to buy little articles at the rancho where we stayed. 
It was supposed 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 sepa-

Government of Buenos Ayres for the obliging manner in which passports

rated these Indians into two classes ; but this is certainly incor- 
rect. 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 orna- 
mented by broad bracelets of blue beads. Nothing could be 
more interesting than some of the family groups. A mother 
with one or two daughters would often come to our rancho, 
mounted on the same 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, ueeful 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, 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 
Ihe 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 bridle 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 Rosas intimated a wish to see me; a circumstance 
which I was afterwancls very glad of. He is a man of an extra- 
ordinary character, and has a most predominant influence in the 
country, which it seems probable he will use to its prosperity 



1833.] GENERAL ROSAS. 73 

and advancement.* He is said to be the owner of seventy-four 
square leagues of land, and to have about three hundred thou- 
sand 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 Jiis own estancias, and by disciplin- 
ing 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 estan- 
cia a visit, and General Rosas, 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 stocks." Such actions as these delighted 
the Gauchos, who all possess high notions of their own equality 
and dignity. 

General Rosas 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. Thia 
extraordinary feat has also been performed by Rosas. 

By these means, and by conforming to the dress and habits of 

* This prophecy has turned out entirely and miserably -wrong. 1845 



74 RIO COLORADO. [CHAP. iv. 

Ihe 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 Rosas, so I killed him." 
At the end of a week the murderer was at liberty. This doubt- 
less 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 
following 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 en- 
gaged.' 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 riot do ; when the 
general laughs he spares neither mad man nor sound." The 
poor flighty gentleman looked quite dolorous, at the very recol- 
lection 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. 

In 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 mouth 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 intc 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 



1833.] SAND-DUNES. 75 

river, we soon entered on a country, differing from the plains 
south of the river. The land still continued dry and sterile ; 
but it supported many different kinds of plants, and the grass, 
though brown and withered, was more abundant, as the thorny 
bushes were less so. These latter in a short space entirely dis- 
appeared, and the plains were left without a thicket to cover 
their nakedness. This change in the vegetation marks the com- 
mencement of the grand calcareo argillaceous deposit, 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 charac- 
teristic 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 east 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 advan- 
tage 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 Rio Negro and Colorado were 
caused by trifling inequalities in the plain ; without them not a 
drop of water would have been found. The bolt 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 land occur, such speculations can hardly be 
neglected by any one, although 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 



76 BAHIA BLANCA. [CHAP. iv. 

between the Colorado and Buenos Ayros 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 eat 
tvith 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 



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 stand- 
ing (since 1828) ; and its growth has been one of trouble. The 
government of Buenos Ayres unjustly occupied it by force, in- 
stead of 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 tho 
limits of the walls : even the cattle are not safe from the attacks 



1833.] AN ATTACK BY THE INDIANS. 77 

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 Comman- 
dant 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 mud. Some 
parts were clothed by low thickets, and others with those succu- 
lent plants, which luxuriate only where salt abounds. Bad as 
the country was, ostriches, deers, agoutis, and armadilloes, were 
abundant. My guide told me, that two months 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 chace, 
soon overtook 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. Springing on the saddle, he managed, by a most wt>n- 
derful exertion, just to keep ahead of the long spears of his pur- 
suers, 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 niglit, 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 poor ones, and in the morning 
they were soon exhausted from not having had any thing to 
drink, so that we were obliged to walk. About noon the dogs 



78 BAHIA BLANCA. [CHAP. iv. 

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 trou- 
blesome 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 incrustations 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 s&e 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. Par- 
chappe* found that the saline incrustation on the piain, 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 increased to 37 parts in a hundred. 
This circumstance would tempt one to believe that the sulphate 
of soda is generated in the soil, from the muriate, left on the 

* Voyage dans 1'Amerique Merid. par M. A. d'Orbigny. Part. Hist 
torn. i. p. 664. 



1833.] AN ADVENTURE. 79 

surface during the slow and recent elevation of this dry country. 
The whole phenomenon is well worthy the attention of natural- 
ists. 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 dis- 
mounted, and watching them intently, said, " They don't ride 
like Christians, and nobody can leave the fort." The three 
hunters joined company, 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 ii^tant horizon. I thought his un- 
common coolness too good a joke, and asked him why he did not 
return 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 our pace. He said, 
" No, not until they do." When any little inequality concealed 
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 ; he 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 be the wife and sister-in-law of the major's son, hunting 
for ostrich's eggs. I have described this man's conduct, because 
he acted under the full impression that they were Indians. As 
soon, however, as the absurd mistake was found out, he gave ine 



80 BAHIA BLANCA. [CHAP. iv. 

a hundred reasons why they could not have been Indians ; but 
all these were forgotten at the time. We then rode on in peace 
and quietness 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 numerous great 
mud-banks, whicli the inhabitants call Cangrejales, or crabberies, 
from the number of small crabs. The mud is so soft that it is 
impossible to walk over them, even for the shortest distance. 
Many of the banks have their surfaces covered with long rushes, 
.he 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 the 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 clay 
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 run- 
ning at the nose. Whatever is once polluted by it, is for ever 
useless. Azara says the smell can be perceived at a league dis- 
tant ; more than once, when entering the harbour of Monte 
Video, the wind being off shore, we have perceived the odour 
on board the Beagle. Certain it is, that every animal most will- 
ingly makes room for the Zorillo.

BAHIA BLANCA. 

THE Beagle arrived here on the 24th of August, and a week after- 
wards sailed for the Plata. With Captain Fitz Roy'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 sur- 
veying 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 eleva- 
tion we have evidence in upraised beds of recent shells, and in 
rounded pebbles of pumice scattered over the country. At 
Punta Alta we have a section of one of these later-formed little 
plains, which is highly interesting from the number and extra- 
ordinary character of the remains of gigantic land-animals em- 
bedded in it. These have been fully described by Professor 
Owen, in the Zoology of the voyage of the Beagle, and are depo- 
sited 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 Megathe- 
rium, the huge dimensions of which are expressed by its name. 
Secondly, the Megalonyx, a great allied animal. Thirdly, the 
Scclidotlierium, also an allied animal, of which I obtained a 



82 BAIIIA BLAXCA. [CHAP. T. 

nearly perfect skeleton. It must have been as large as a rhino- 
ceros : 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, 
ft closely related genus of little inferior size. Fifthly, another gi- 
gantic edental quadruped. Sixthly, a large animal, with an osseous 
soat 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 Toxodon, 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 the position of its eyes, ears, and 
nostrils, it was probably aquatic, like the Dugong and Manatee, 
to which it is also allied. How wonderfully 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 de- 
tached bones were found embedded on the beach, within the 
space of about 200 yards square. It is a remarkable circum- 
stance 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 P. Alta, in a cliff of red earth, I found several frag- 
ments 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, ac- 
cording 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 






1833.] EXTINCT QUADRUPEDS. 83 

and reddish mud, just such as the sea might now wash up on a 
shallow bank. They were associated with twenty-three species 
of shells, of which thirteen are recent and four others very 
closely related to recent forms ; whether ,he remaining ones are 
extinct or simply unknown, must be uoubtful, as few collections 
of shells have been made on this coast. As, however, the recent 
species were embedded in nearly the same proportional numbers 
with those now living in the bay, I think there can be little 
doubt, that this accumulation belongs to a very late tertiary 
period. From the bones of the Scelidotheriiim, including even 
the knee-cap, being intombed in their proper relative positions, 
and from the osseous armour of the great armadillo-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. 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 quadru- 
peds 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."* 

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 Owenf lately 
solved the problem with remarkable ingenuity. The teeth in- 
dicate, 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,

Beagle, aud subsequently in Professor Oweu!s Meaioir on Mylodon ro- 
bustus. 



84 BAHIA BLANCA. [CHAP. v. 

not to say preposterous, idea to conceive even antediluvian trees, 
with branches strong enough to bear animals as large as ele- 
phants. Professor Owen, with far more probability, believes 
that, instead of climbing on the trees, they 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 incumbrance : their apparent clumsiness disappears. 
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 giraife, 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 Abj'ssinia the 
elephant, according 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 land 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 sur- 
rounding plains ; and the external features of the country must 
then have been very nearly the same as now. What, it may natu- 
rally 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 vegeta- 
tion was probably similar to the existing one ; but this would 
have been an erroneous inference, 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 considera- 
tions, I do not believe that the simple fact of many gigantic 
quadrupeds having lived on the plains round Bahia Blanca, is 



1833.] FOOD OF LARGE QUADRUPEDS. 85 

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 Rio 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 ; 
hut I do not hesifate 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 cha- 
racter of the country, or to the numbers of large animals inha- 
biting 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 sufficient to render that which I had read more fully intel- 
ligible. 

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 

* I raean by this to exclude the total amount, -which may have been suc- 
cessively produced and consumed during a given period. 



BAHIA BLANCA. [CHAP. 



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 supposed that although the species are numerous, the indivi- 
duals of each kind are few. By the kindness of Dr. Smith, I 
am enabled to show that the case is very different. He informs 
me, that in lat. 24, in one day's march with the bullock- wag- 
gons, he 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 day he saw several 
herds of giraffes, amounting together to nearly a hundred ; and 
that, although no elephant was observed, yet they are 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 croco- 
diles. 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 day, as " being 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 hyaena, and the multitude of birds of prey, plainly speak of 
the abundance of the 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 producing so little food. The larger qua- 



1833.] FOOD OF LARGE QUADRUPEDS. 87 

drupeds no doubt roam over wide tracts in search of it ; and 
their food chiefly consists of underwood, 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 con- 
sumed, 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 large 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, the vegetation 
must necessarily be luxuriant, is the more remarkable, because 
the converse is far from true. Mr. Burchell observed to me 
that when 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 com- 
parison 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 along- 
side each other, it is not easy to conceive ranks more dispro- 
portionate in size. After the above facts, we are compelled to 

* Travels in the Interior of South Africa, vol. ii., p. 207. 

t The elephant which was killed at Exeter Change was estimated (heing 
partly weighed) at five tons and a half. The elephant actress, as I was in- 
formed, 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 over- 
stating the result. The ratio will therefore be as 6048 to 250, or 24 to 1, for 
the ten largest animals from the two continents. 






BAHIA BLANCA. [CHAP. v. 



conclude, against anterior probability,* that among the mam- 
malia there exists no close relation between the bulk of the 
species, and the quantity of the vegetation, in the countries 
which they inhabit. 

With regard to the number of large quadrupeds, there cer- 
tainly 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. 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 accu- 
mulated 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 vegetation, 
when we see a state of things so totally different at the Cape 
of Good Hope. 

We knowf 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 iatitudej 
(64), where the mean temperature of the air falls below the 
freezing point, and where the earth is so completely frozen, that 

* If we suppose the case of the discovery of a skeleton of a Greenland 
frhale in u 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 ? 

t See Zoological Remarks to Capt. Back's Expedition, by Dr. Richardson. 
He says, " The subsoil north of latitude 50 is perpetually frozen, the thaw 
ou 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, fur forests flourish on the surface, at a distance from the 
coast."

Plants : and Malte Brun. In the latter work it is said that the limit of the

the carcass of an animal embedded in it is perfectly preserved. 
With these facts we must grant, as far as quantity alone of vege 
lation is concerned, that the great quadrupeds of the later ter- 
tiary epochs might, in most parts of Northern Europe and Asia, 
have lived on the spots where their remains are now found. 1 
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 con- 
viction of the necessity of a vegetation possessing a character of 
tropical luxuriance, to support such large animals, and the im- 
possibility 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 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 more 
interesting birds which are common on the wild plains of North- 
ern 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 dif- 
ficulty 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 prclei

running against the wind ; yet at the first start they expand 
their wings, and like a vessel make all sail. On one fine hoi 
day I saw several ostriches enter a bed of tall rushes, where they 
squatted concealed, till quite closely approached. It is not gene- 
rally 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 Santa Cruz river, where its course was about four hundred 
yards wide, and the stream rapid. Captain Sturt,* when de- 
scending the Murrumbidgee, 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 
darker-coloured,t 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 comes, 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 afterwards accompanies the young. 

* Sturt's Travels, vol. ii. p. 74. 

f A Gauche assured me that he had once seen a snow-white or Albino 
rariety, and that it was a most beautiful bird. 



1833.] HABITS OF THE OSTRICH. 91 

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 occa- 
sionally 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 Hoi ten- 
tots to be a nest bird." I understand that the male emu in the 
Zoological Gardens takes charge of the nest: this habit, there- 
fore, 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.* Although 
this habit at first appears very strange, I think the cause may 
be explained in a simple manner. The number of eggs in thp 
nest vanes from twenty to forty, and even to fifty ; and accord- 
ing to Azara, sometimes to seventy or eighty. Now although 
it is most probable, from the number of eggs found in one dis- 
trict being so extraordinarily 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 inter- 
val 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 



* Burchell's Travels, vol. i. p. 280. 
f Azara, vol. iv. p. 1 73. 



92 BAHIA BLANC A. [CHAP. v. 

females probably could not sit, from net having finished laying.* 
I have before mentioned the great numbers of huachos, or de- 
serted 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 to- 
gether, and finding a male ready to undertake the office of incu- 
bation ? 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, are generally whole. 

When at the Rio 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 com- 
mon ostrich (which is there abundant), but with a very close 
general resemblance. 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 other species. The few inhabitants who had seen 
both kinds, affirmed they could distinguish them apart from a 
long distance. The eggs of the small species appeared, however, 
more generally known ; and it was remarked, with surprise, that 
they were very little less than those of the Rhea, but of a slightly 
different form, and with a tinge of pale blue. This species occurs 
most rarely on the plains bordering the Rio 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 
Petises, and thought it was a not full-grown bird of the com- 
mon sort. It was cooked and eaten before my memory returned 

* Liechtenstein, however, asserts (Travels, vol. ii. p. 25) that the hens b^gk 
sitting when they have laid ten or twelve eggs ; and that they continue 
laying, I presume, in another nest. This appears to me very improbable 
He asserts that four or five hens associate for incubation with one cock, who 
site only at night 



1833.] THE AVESTRUZ PETISE. 93 

Fortunately the head, neck, legs, wings, many of the larger 
feathers, and a large part of the skin, had been preserved ; 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 deposited 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 win^s, when first starting at full speed, after the manner of 
the northern kind. In conclusion I may observe, that the Stru- 
thio rhea inhabits the country of La Plata as far as a little south 
of the Rio Negro in lat. 41, and that the Struthio Darwinii 
takes its place in Southern Patagonia ; the part about the Rio 
Negro being neutral territory. M. A. d'Orbigny,* when at the 
Rio Negro, made great exertions to procure this bird, but never 
had the good fortune to succeed. Dobrizhoffer f 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 
different 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 

* When at the Rio Negro, we heard much of the indefatigable labours of 
iLis naturalist. M. Alcide d'Orbigny, during the years 1825 to 1833, tra- 
versed several large portions of South America, and has made a collection, 
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 Humbolit. 

< Account of the Abipones, A.D. 1749, vol. i. (English translation), p. 314 



94 BAHIA BLANCA. [CHAP. v. 

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 desokte 
places, where scarcely another living creature can exist. Upon 
being approached they squat close, and then are very difficult to 
be distinguished 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 appear- 
ance changes ; the long pointed wings, so different from those in 
the gallinaceous order, the irregular manner of flight, and plain- 
tive cry uttered at the moment of rising, recal 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 Ame- 
rican birds. Two species of the genus Attagis are in almost 
every respect ptarmigans in their habits ; one lives in Tierra del 
Fuego, above the limits of the forest land ; and the other jusi 
beneath the snow-line on the Cordillera of Central Chile. A 
bird of another closely allied genus, Chionis alba, is an inha- 
bitant of the antarctic regions ; it feeds on sea-weed and shells 
on the tidal rocks. Although not web-footed, from some unac- 
countable habit, it is frequently met with far out at sea. This 
small family of birds is one of those which, from its varied rela- 
tions to other families, although at present offering only difficul- 
ties to the systematic naturalist, ultimately may assist in revealing 
the grand scheme, common to the present and past ages, on 
which organized beings have been created. 



1833.] THE OVEN-BIRD. 95 

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 
housemaker 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 mud and 
bits of straw, and 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 plu- 
mage, 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 !">, 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 complained of the little 
casarita, several of which I afterwards observed at work. It is 
rather curious to find how incapable these birds must be of ac- 
quiring any notion of thickness, for although they were con- 
stantly flitting over the low wall, they continued vainly to 
bore through it, thinking it an excellent bank for their nests. 1 
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 
hi this country Of armadilloes three species occur, namely,

the L>asypus mitnitus or picky, the D. villosus or peludo, and 
the npar. The first extends ten degrees further south than any 
otner 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 ma- 
tnco, 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 oi 
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 the 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 Trigono- 
cephalus, 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 inter- 
mediate between it and the viper. In confirmation of this opi- 
nion, I observed a fact, which appears to me very curious and 
instructive, as showing how every character, even though it may 
be in some 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, pro- 
duces a rattling noise, which can be distinctly heard at the dis- 






1833.] CURIOUS SNAKE. 97 

taiice of six feet. As often as the animal was irritated 01 
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 Trigo- 
nocephalus has, therefore, in some respects the structure of a 
/iper, with the habits of a rattlesnake : the noise, however, being 
produced by a simpler device. The expression 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 any thing more ugly, excepting, perhaps, 
some of the vampire bats. I imagine this repulsive aspect ori- 
ginates 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 Batrachian reptiles, I found only one little toari 
(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 vtrnnllion, so as to colour the soles oi 
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 Mal- 
donado, 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 unable to swim, but, I 
think without help it would soon have been drowned. 

Of lizards there were many kinds, but only one (Proctotretus 
multimaculatus) remarkable from its habits. It lives on the 
bare sand near the sea coast, and from its mottled colour, the 
brownish scales being 1 speckled with white, yellowish red, and 
dirty blue, can hardly be distinguished from the surrounding 



BAHIA BLANCA. [CHAP. 



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 quick- 
ness 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 hybernation 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), every thing announced the commencement of 
spring. The plains were ornamented by the flowers of a pink 
wood-sorrel, wild peas, cenotherge, and geraniums ; and the birds 
began to lay their eggs. Numerous Lamellicorn and Hetero- 
merous 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 direc- 
tion. During the first eleven aays, 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 
sixty and seventy. Here then an increase of seven degrees in 
mean temperature, but a greater one of extreme heat, was suffi- 
cient 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 es .^, and the coldest 46. The lowest point to 
which the thermometer fell was 41.5, and occasionally 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, which 
is four degrees southward, and therefore with a climate only a 
i r ery little coluer, this same temperature with a rather less ox- 



1833.] SEA-PEN. 



treme heat, was sufficient to awake all orders of animated beings. 
This shows how nicely the stimulus required to arouse hybernat- 
ing 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 determined not by the temperature, but by the times of 
drought. Near Rio de Janeiro, I was at first surprised to ob- 
serve, 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. Hum- 
boldt 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 lethar- 
gic state. To reanimate them, they must be 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, pro- 
jecting like stubble, with the truncate end upwards, a few inches 
above the surface of the muddv sajid. 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 poly- 
pus, 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.* 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, nar- 
rates 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 great- 
ness, 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 Indian* (mansos, or tame), 
belonging to the tribe of the Cacique Bernantio. They passed 

were filled with a yellow pulpy matter, which, examined under a micro- 
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 mat- 
ter, eome of large size, as soon as they were disengaged, commence revolv- 
ing. I have imagined, I know not with how much truth, that this grannlo- 
pulpy matter was in process of being converted into ova. Certainly in thJe 
Koophyte such appeared to be the case.

1833.] EXPEDITION AGAINST THE INDIANS. 101 

the night here ; and it was impossible to conceive any thing 
more wild and savage 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 drunkenness, they cast it up again, and were besmeared 
with filth and gore. 

Nam simul expletus dapibus, vinoque sepultus 
Cervicem inflexam posuit, jacuitque per antrum 
Immensus, saniem eructans, ac frusta cruenta 
Per SOIUQUIU commixta mero. 

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. Supposing 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 footsteps, 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 consider 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 Cholechel, situated seventy leagues up the Rio 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, 
mares' 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 engage- 
ment at which he was present. Some Indians, who had been 
taken prisoners, gave information of a tribe living north of the 



102 " BAHIA BLANCA. [CHAP. T. 

Colorado. Two hundred soldiers were sent ; and they first dis- 
covered the Jndians by a cloud of dust from their horses' feet, 
as they chanced to be travelling 1 . The country was mountainous 
and wild, and it must have been far in the 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 over- 
taken, 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 he 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 my 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 shock- 
ing 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 breed 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 togther. 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 oi 
Indians, united in the common cause of defence, near the Cor- 
dillera. The 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 



1833.] CAPTIVE INDIANS. 103 

men, very fair, above six feet high? and all under thirty years oi 
age. The three survivors of course possessed very valuable 
information ; and to extort this they were placed in a line. The 
two first being questioned, answered, " No se " (I do not know), 
and were one 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 communication, therefore, between the Indians, 
extends from the Cordillera to the coast of the Atlantic. 

General Rosas'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 directions. The escape of the Indians to the 
south of the Rio Negro, where in such a vast unknown country 
they would be safe, is prevented by a treaty with the Tehuelches 
to this effect ; that Rosas pays them so much to slaughter every 
Indian who passes to the south of the river, but if they fail in so 
doing, they themselves are to be exterminated. The war is 
waged chiefly against the Indians near the Cordillera ; for many 
of the tribes on this eastern side are fighting with Rosas. 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 exter- 
mination 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 

8 



104 BAHIA BLANCA. [CHAP. v. 

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 Rio 
Negro. The warfare is too bloody to last ; the Christians killing 
every Indian, and the Indians doing the same by the Christians. 
It is melancholy to trace how 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 inhabitants. 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 chace, 
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 pur- 
suers urged every effort in the chace ; the Commandant three 
times changed his horse, but all in vain. The old Indian father 
and his son escaped, and were free. What a fire 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 
opake 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 widely separated 
from the Pampas Indians, and border uiose 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 introduction of the 
horse into South America. 

* Azara haa even doubted whether the Pampas Iiidians ever used bows.

BAHIA BLANCA TO BUENOS 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 dis- 
tance, he would mistake it for an Indian, and would fly like the 
wind away. The distance to Buenos Ayres is about four hun- 
dred 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 great distance in the interior, 
being on fire. After a long gallop, having changed horses twice, 
we reached the Rio 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 sea, it is quite 
impassable, and hence makes a most useful barrier against the 
Indians. 



1833.] SIERRA VENT AN A. IOY 

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 Gau- 
chos 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 extremely 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 ja. 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 Roy 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 ascended 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. die friable calcareous stone and loose detritus. I do not 
think Nature ever made a more solitary, desolate pile of rock ; 



108 BAHIA BLANCA TO BUENOS AYRES. [CHAP. vi. 

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 view ; the whit- 
ish 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 frag- 
ments. 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 be found. 
On the shores of Bahia Blanca, and near the settlement, there 
were some of quartz, which certainly must have come from thi? 
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 trans- 
versely 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 moun 
tain, like the other, was steep and rugged. I was on the top oi 
the second peak by two o'clock, but got there with extreme dif- 
ficulty ; 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 highei 
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 climbing. 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 be- 
neath the 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 
beautiful 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 com- 
panions made a good fire a thing which is never done when il 
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 aguanaco. The plain, which abuU against the Sierra, 
is traversed by some curious gulleys, of which one was about 
twenty feet wide, and at .least thirty deep ; we were obliged in 
consequence to make a considerable circuit before we could find 
a pass. We stayed the night at the posta, the conversation, as was 
generally the case, being about the Indians. The Sierra Ven- 
tana was formerly a great place of resort ; and three or four 
years ago there was much righting 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 \\th. 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 over- 
stated. 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, 
guarded by fifteen soldiers ; but we were told many had been 
lost. It is very difficult to drive animals across the plains ; for 
if in the night a puma, or even a fox, approaches, nothing can 
prevent the horses dispersing 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 companions 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 uncom- 
mon degree the wildness of their appearance. They turned oul 
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 

Travels in Africa, p. 233. 



1833.] THROWING THE BOLAS. Ill 

food who have an unconquerable desire for salt. The Indians 
gave us good-humoured nods as they passed at full gallop, driv- 
ing before them a troop of horses, and followed by a train of 
lanky dogs. 

September 12/7* 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 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 ths 
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, 1 
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, Lu- 
ciano 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 forvfarded 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 an- 
other partly a mulatto ; but two such mongrels, with such de- 
testable expressions, I never saw before. At night, when they 
were sitting round the fire, and playing at cards, I retired to 



112 BAIIIA BLANCA TO BUENOS AYRES. [CHAP. vi. 

view such a Salvator Rosa 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 tne conversation, and every head, for a moment, a little 
inclined. 

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 or 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, &c., 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 al sallied forth to hunt, and although we 
had not much success, there were some animated chaces. Sooii 
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, 



1833.] HOSPITALITY. 113 

but the men there merely rode in a crescent, each being about a 
quarter of a mile apart from the other. A fine male ostrich 
being turned by the headmost riders, tried to escape on one side. 
The Gauchos pursued at a 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 oi 
the day we 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 hunting 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 hens' eggs ; so 
that we obtained from this one nest as much food as 297 hens 
eggs would have given. 

September 14th. As the soldiers belonging to the next posta 
meant to return, and we should together make a party of five, 
and all armed, I determined not to wait for the expected troops. 
My host, the lieutenant, pressed me much to stop. As he had 
been very obliging not only providing me with food, but lend- 
ing me his private horses I wanted to make him some remu- 
neration. I asked my guide whether I might do so, but he told 
me certainly not ; that the only answer I should receive, pro 
bably would be, " We have meat for the dogs in our country, 
and therefore do not grudge it to a Christian." It must not be 
supposed that the rank of lieutenant in such an army would at 
all prevent the acceptance of payment : it was only the high 
sense of hospitality, which every traveller is bound to acknow- 
ledge as nearly universal throughout these provinces. After 
galloping some leagues, we came to a low swampy country, which 
extends for nearly eighty miles northward, as far as the Sierra 
Tapalguen. In some parts there were fine damp plains, covered 
with grass, while others had a soft, black, and peaty soil. There

cam only be called a partridge with regard to its habits. 



114 BAHIA BLAXCA TO BUEXOS AYRES. [CHAP. vi. 

were also many extensive but shallow lakes, and large beds of 
reeds. The country on the whole resembled the better parts of 
the Cambridgeshire fens. At night we had some difficulty in 
finding, amidst the swamps, a dry place for our bivouac. 

September 15th. Rose very early in the morning, and shortly 
after passed the posta where the Indians had murdered the five 
soldiers. The officer had eighteen chuzo wounds in his body. 
By the middle of the day, after a hard gallop, we reached the 
fifth posta: on account of some difficulty in procuring horses 
we stayed there the night. As this point was the most exposed 
on the whole line, twenty-one soldiers were stationed here; at 
sunset they returned from hunting, bringing with them seven 
deer, three ostriches, and many armadilloes and partridges. 
When riding through the country, it is a common practice to 
set fire to the plain ; and hence at night, as on this occasion, the 
horizon was illuminated in several places by brilliant conflagra- 
tions. This is done partly for the sake of puzzling any stray 
Indians, but chiefly for improving the pasture. In grassy plains 
unoccupied by the larger ruminating quadrupeds, it seems neces- 
sary to remove the superfluous vegetation by fire, so as to render 
the new year's growth serviceable. 

The rancho at this place did not boast even of a roof, but 
merely consisted of a ring of thistle-stalks, to break the force of 
(he wind. It was situated on the borders of an extensive but 
shallow lake, swarming with wild fowl, among which the black- 
necked swan was conspicuous. 

The kind of plover, which appears as if mounted on stilts, 
(Himantopus nigricollis) is here common in flocks of consi- 
derable size. It has been wrongfully accused of inelegance ; 
when wading about in shallow water, which is its favourite 
resort, its gait is far from awkward. These birds in a flock 
utter a noise, that singularly resembles the cry of a pack of 
small dogs in full chace : waking in the night, I have more than 
once been for a moment startled at the distant sound. Tho 
teru-tero (Vanellus cayanus) is another bird, which often dis- 
turbs the stillness of the night. In appearance and habits it 
resembles in many respects our peewits ; its wings, however, arc 
armed with sharp spurs, like those on the legs of the common 
cock. As our peewit takes its name from the sound of its voice, 



1833.] A VIOLENT HAIL-STORM. 115 

BO does the teru-tero. While riding over the grassy plains, one 
is constantly pursued by these birds, which appear to hate man- 
kind, and I am sure deserve to be hated for their never-ceasing, 
unvaried, harsh screams. To the sportsman they are most an- 
noying, by telling every other bird and animal of his approach : 
to the traveller in the country, they may possibly, as Molina 
says, do good, by warning him of the ir idnight robber. During 
the breeding season, they attempt, like cur peewits, by feigning 
to be wounded, to draw away from their nests dogs and other 
enemies. The eggs of this bird are esteemed a great delicacy. 

September 16th. To the seventh posta at the foot of the Sierra 
Tapalguen. The country was quite level, with a coarse herbage 
and a soft peaty soil. The hovel was here remarkably neat, the 
posts and rafters being made of about a dozen dry thistle- 
stalks bound together with thongs of hide ; and by the support 
of these Ionic-like columns, the roof and sides were thatched 
with reeds. We were here told a fact, which I would not have 
credited, if I had not had partly ocular proof of it ; namely, 
that, during the previous night, hail as large as small apples, 
and extremely hard, had fallen with such violence, as to kill 
the greater number of the wild animals. One of the men had 
already found thirteen deer (Cervus campestris) lying dead, and 
I saw their fresh hides ; another of the party, a few minutes 
after my arrival, brought in seven more. Now I well know, 
that one man without dogs could hardly have killed seven deer 
in a week. The men believed they had seen about fifteen dead 
ostriches (part of one of which we had for dinner) ; and they 
said that several were running about evidently blind in one eye. 
Numbers of smaller birds, as ducks, hawks, and partridges, were 
killed. I saw one of the latter with a black mark on its back, 
as if it had been struck with a paving-stone. A fence of thistle- 
stalks round the hovel was nearly broken down, and my in- 
former, putting his head out to see what was the matter, received 
a severe cut, and now wore a bandage. The storm was said to 
have been of limited extent : we certainly saw from our last 
night's bivouac a dense cloud and lightning in this direction. It 
is marvellous how such strong animals as deer could thus have 
been killed ; but I have no doubt, from the evidence I have 
given, that the story is not in the least exaggerated. I am glad, 



116 BAHIA BLANCA TO BUENOS AYRES. [CHAP. vi. 

however, to have its credibility supported by the Jesuit Drobriz- 
hoffer,* who, speaking of a country much to the northward, 
Bays, hail fell of an enormous size and killed vast numbers oi 
cattle: the Indians hence called the place Lalegraicavalca, 
meaning " the little white things." Dr. Malcolmson, also, in- 
forms me that he witnessed in 1831 in India, a hail-storm, which 
killed numbers of large birds and much injured the cattle. 
These hail-stones were flat, and one was ten inches in circum- 
ference, and another weighed two ounces. They ploughed up a 
gravel-walk like musket-balls, and passed through glass-windows, 
making round holes, but not cracking them. 

Having finished our dinner of hail-stricken meat, we crossed 
the Sierra Tapalguen ; a low range of hills, a few hundred feet 
in height, which commences at Cape Corrientes. The rock in 
this part is pure quartz ; further eastward I understand it is gra- 
nitic. ' The hills are of a remarkable form ; they consist of flat 
patches of table-land, surrounded by low perpendicular cliffs, 
like the outliers of a sedimentary deposit. The hill which I 
ascended was very small, not above a couple of hundred yards 
in diameter ; but I saw others larger. One which goes by the 
name of the " Corral," is said to be two or three miles in dia- 
meter, and encompassed by perpendicular cliffs between thirty 
and forty feet high, excepting at one spot, where the entrance 
lies. Falconerf gives a curious account of the Indians driving 
troops of wild horses into it, and then by guarding the entrance, 
keeping them secure. I have never heard of any other instance 
of table land in a formation of quartz, and which, in the hill I 
examined, had neither cleavage nor stratification. I was told 
that the rock of the " Corral" was white, and would strike fire. 

We did not reach the posta on the Rio Tapalguen till after it 
was dark. At supper, from something which was said, I was 
suddenly struck with horror at thinking that I was eating one oi 
the favourite dishes of the country, namely, a half-formed calf, 
long before its proper time of birth. It turr ed out to be Puma ; 
the meat is very white, and remarkably like veal in taste. Dr. 
Shaw was laughed at for stating that " the flesh of the lion is 
in great esteem, having no small affinity with veal, both in 

* History of the Abipones, vol. ii. p. 6.

1833.] MEAT DIET. 117 

colour, taste, and flavour." Such certainly is the case with the 
Puma. The Gauchos differ in their opinion, whether the Ja- 
guar is good eating, but are unanimous in saying that cat is ex- 
cellent. 

September \llh. We followed the course of the Rio Tapal- 
guen, through a very fertile country, to the ninth posta. Tapal- 
guen itself, or the town of Tapalguen, if it may be so called, 
consists of a perfectly level plain, studded over, as far as the eye 
can reach, with the toldos, or oven -shaped huts of the Indians. 
The families of the friendly Indians, who were fighting on the 
side of Rosas, resided here. We met and passed many young 
Indian women, riding by two or three together on the same 
horse : they, as well as many of the young men, were strikingly 
handsome, their fine ruddy complexions being the picture of 
health. Besides the toldos, there were three ranches ; one in- 
habited by the Commandant, and the two others by Spaniards 
with small shops. 

We were here able to buy some biscuit. I had now been 
several days without tasting any thing besides meat : I did not 
at all dislike this new regimen ; but I felt as if it would only 
have agreed with me with hard exercise. I have heard that 
patients in England, when desired to confine themselves exclu 
sively to an animal diet, even with the hope of life before their 
eyes, have hardly been able to endure it. Yet the Gaucho in 
the Pampas, for months together, touches nothing but beef. 
But they eat, I observe, a very large proportion of fat, which is 
of a less animalized nature ; and they particularly dislike dry 
meat, such as that of the Agouti. Dr. Richardson,* also, has 
remarked, " that when people have fed for a long time solely 
upon lean animal food, the desire for fat becomes so insatiable, 
that they can consume a large quantity of unmixed and even oily 
fat without nausea :" this appears to me a curious physiological 
fact. It is, perhaps, from their meat regimen that the Gauchos, 
like other carnivorous animals, can abstain long from food. I 
was told that at Tandeel, some troops voluntarily pursued a party 
of Indians for three days, without eating or drinking. 

We saw in the shops many articles, such as horsecloths, bolts. 

* Fauna Boreali- Americana, vol. i. p. 85. 



118 BAHIA BLANCA TO BUENOS AYRES. [CHAP. vi. 

and garters, woven oy the Indian women. The patterns were 
very pretty, and the colours brilliant ; the workmanship of the 
garters was so good that an English merchant at Buenos Ay res 
maintained they must have been manufactured in England, till 
he found the tassels had been fastened by split sinew. 

September ISth. We had a very long ride this day. At the 
twelfth posta, whi:h is seven leagues south of the Rio Salado, 
we came to the first estancia with cattle and white women. 
Afterwards we had to ride for many miles through a country 
flooded with water above our horses' knees. By crossing the 
stirrups, and riding Arab-like with our legs bent up, we con- 
trived to keep tolerably dry. It was nearly dark when we 
arrived at the Salado ; the stream was deep, and about forty 
yards wide ; in summer, however, its bed becomes almost dry, 
and the little remaining water nearly as salt as that of the sea. 
We slept at one of the great estancias of General Rosas. It was 
fortified, and of such an extent, that arriving in the dark 1 
thought it was a town and fortress. In the morning we saw 
immense herds of cattle, the general here having seventy-four 
square leagues of land. Formerly nearly three hundred men 
were employed about this estate, and they defied all the attacks 
of the Indians. 

September 19th. Passed the Guardia del Monte. This is a 
nice scattered little town, with many gardens, full of peach and 
quince trees. The plain here looked like that around Buenos 
Ayres ; the turf being short and bright green, with beds of 
clover and thistles, and with bizcacha holes. I was very much 
struck with the marked change in the aspect of the country after 
having crossed the Salado. From a coarse herbage we passed on 
to a carpet of fine green verdure. I at first attributed this to 
some change in the nature of the soil, but the inhabitants 
assured me that here, as well as in Banda Oriental, where there 
is as great a difference between the country around Monte Video 
and the thinly-inhabited savannahs of Colonia, the whole was 
to be attributed to the manuring and grazing of the cattle. 
Exactly the same fact has been observed in the prairies* of North 
America, where coarse grass, between five and six feet high, 

* See Mr. Atwater's account of the Prairies, in Silliman's X. A. Journal 
vol. L p. 117. 



1833.] THE CARDOOX. 119 

when grazed by cattle, changes into common pasture land. I 
am not botanist enough to say whether the change here is owing 
to the introduction of new species, to the altered growth of the 
same, or to a difference in their proportional numbers. Azara 
has also observed with astonishment this change : he is likewise 
much perplexed by the immediate appearance of plants not oc- 
curring in the neighbourhood, on the borders of any track that 
leads to a newly-constructed hovel. In another part he says,* 
" ces chevaux (sauvages) ont la manie de preferer les chemins, 
et le bord des routes pour deposer leurs excremens, dont on trouve 
des monceaux dans ces endroits." Does this not partly explain 
the .circumstance? We thus have lines of richly-manured land 
serving as channels of communication across wide districts. 

Xear the Guardia we find the southern limit of two European 
plants, now become extraordinarily common. The fennel in 
great profusion covers the ditch-banks in the neighbourhood of 
Buenos Ayres, Monte Video, and other towns. But the cardoon 
(Cynara cardunculus)']' has a far wider range : it occurs in these 
latitudes on both sides of the Cordillera, across the continent. 
I saw it in unfrequented spots in Chile, Entre Rios, and Banda 
Oriental. In the latter country alone, very many (probably 
several hundred) square miles are covered by one mass of these 
prickly plants, and are impenetrable by man or beast. Over the 
undulating plains, where these great beds occur, nothing else 
can now live. Before their introduction, however, the surface 
must have supported, as in other parts, a rank herbage. I 
doubt whether any case is on record of an invasion on so grand 
a scale of one plant over the aborigines. As I have already 
said, I nowhere saw the cardoon south of the Salado ; but it is 

* Azara's Voyage, vol. 5. p. 373. 

f M. A. d'Orbigny (vol. i. p. 474) says that the cardoon and artichoke are 
both found wild. Dr. Hooker (Botanical Magazine, vol. Iv. p. 2862), has 
described a variety of the Cynara from this part of South America under 
the name of inermis. He states that botanists are now generally agreed that 
the cardoon and the artichoke are varieties of one plant. I may add, that an 
intelligent farmer assured me that he had observed in a deserted garden 
some artichokes changing into the common cardoon. Dr. Hooker believes 
that Head's vivid description of the thistle of the Pampas applies to the car- 
doon ; but this is a mistake. Captain Head referred to the plant, which I 
have mentioned a few lines lower down, under the title of giant thistle 
Whether it is a true thistle, I do not know ; but it is quite different from tlif 
cardoon ; and more like a thistle properly so called. 



120 BAHIA BLANCA TO BUENOS AYRES. [CHAP. vi. 

probable that in proportion as that country becomes inhabited, 
the cardoon will extend its limits. The case is different with 
the giant thistle (with variegated leaves) of the Pampas, for I 
met with it in the valley of the Sauce. According to the 
principles so well laid down by Mr. Lyell, few countries have 
undergone more remarkable changes, since the year 1 535, when 
the first colonist of La Plata landed with seventy-two horses. 
The countless herds of horses, cattle, and sheep, not only have 
altered the whole aspect of the vegetation, but they have almost 
banished the guanaco, deer, and ostrich. Numberless other 
changes must likewise have taken place ; the wild pig in some 
parts probably replaces the peccari ; packs of wild dogs may. be 
heard howling on the wooded banks of the less frequented streams ; 
and the common cat, altered into a large and fierce animal, in- 
habits rocky hills. As M. d'Orbigny has remarked, the increase 
in numbers of the carrion-vulture, since the introduction of the 
domestic animals, must have been infinitely great ; and we have 
given reasons for believing that they have extended their southern 
range. No doubt many plants, besides the cardoon and fennel, 
are naturalized ; thus the islands near the mouth of the Parana, 
are thickly clothed with peach and orange trees, springing from 
seeds carried there by the waters of the river. 

While changing horses at the Guardia several people ques- 
tioned us much about the army, I never saw any thing like the 
enthusiasm for Rosas, and for the success of the " most just oi 
all wars, because against barbarians." This expression, it must 
be confessed, is very natural, for till lately, neither man, woman, 
nor horse, was safe from the attacks of the Indians. We had a 
long day's ride over the same rich green plain, abounding with 
various flocks, and with here and there a solitary estancia, and 
its one ombu tree. In the evening it rained heavily : on arriv- 
ing at a post-house we were told by the owner that if we had 
not a regular passport we must pass on, for there were so many 
robbers he would trust no one. When he read, however, my 
passport, which began with " El Naturalista Don Carlos," his 
respect and civility were as unbounded as his suspicions had been 
before. What a naturalist might be, neither he nor his country- 
men, I suspect, had any idea ; but probably my title lost nothing 
of its value from that cause. 



1833.] THE GREAT CORRAL. 121 

September 20th. We arrived by the middle of the day at 
Buenos Ayres. The outskirts of the city looked quite pretty, 
with the agave hedges, and groves of olive, peach, and willow 
trees, all just throwing out their fresh green leaves. I rode to 
the house of Mr. Lumb, an English merchant, to whose kind- 
ness and hospitality, during my stay in the country, I was greatly 
indebted. 

The city of Buenos Ayres is large ;* and I should think one 
of the most regular in the world. Every street is at right angles 
to the one it crosses, and the parallel ones being equidistant, the 
houses are collected into solid squares of equal dimensions, which 
are called quadras. On the other hand, the houses themselves 
are hollow squares ; all the rooms opening into a neat little 
courtyard. They are generally only one story high, with flat 
roofs, which are fitted with seats, and are much frequented by 
the inhabitants in summer. In the centre of the town is the 
Plaza, where the public offices, fortress, cathedral, &c., stand. 
Here also, the old viceroys, before the revolution, had their 
palaces. The general assemblage of buildings possesses consider- 
able architectural beauty, although none individually can boast 
of any. 

The great corral, where the animals are kept for slaughter to 
supply food to this beef-eating population, is one of the spectacles 
best worth seeing. The strength of the horse as compared to 
that of the bullock is quite astonishing : a man on horseback 
having thrown his lazo round the horns of a beast, can drag it 
any where he chooses. The animal ploughing up the ground 
with outstretched legs, in vain efforts to resist the force, generally 
dashes at full speed to one side ; but the horse immediately turn- 
ing to receive the shock, stands so firmly that the bullock is 
almost thrown down, and it is surprising that their necks are not 
broken. The struggle is not, however, one of fair strength ; 
the horse's girth being matched against the bullock's extended 
neck. In a similar manner a man can hold the wildest horse, iJ 
caught with the lazo, just behind the ears. When the bullock 
has been dragged to the spot where it is to be slaughtered, the 
matador with great caution cuts (he hamstrings. Then is given

;he death bellow ; a noise more expressive of fierce agony than 
any I know : I have often distinguished it from a long distance, 
and have always known that the struggle was then drawing to a 
close. The whole sight is horrible and revolting : the ground is 
almost made of bones; arid the horses and riders are drenched 
with gore.

BUENOS AYRES TO ST. FE . 

September 27th. IN the evening I set out on an excursion to 
St. Ft, which is situated nearly three hundred English milea 
from Buenos Ayres, on the banks of the Parana. The roads in 
the neighbourhood of the city, after the rainy weather, were 
extraordinarily bad. I should never have thought it possible 
for a bullock waggon to have crawled along : as it was, they 
scarcely went at the rate of a mile an hour, and a man was kept 
ahead, to survey the best line for making the attempt. The 
bullocks were terribly jaded : it is a great mistake to suppose 
that with improved roads, and an accelerated rate of travelling, 
the sufferings of the animals increase in the same proportion. 
We passed a train of waggons and a troop of beasts on their 
road to Mendoza. The distance is about 580 geographical miles, 
and the journey is generally performed in fifty days. These wag- 
gons are very long, narrow, and thatched with reeds ; they have 
only two wheels, the diameter of which in some cases is as much 
as ten feet. Each is drawn by six bullocks, which are urged on 
by a goad at least twenty feet long : this is suspended from 
within the roof; for the wheel bullocks a smaller one is kept ; 
and for the intermediate pair, a point projects at right angles 
from the middle of the long one. The whole apparatus looked 
like some implement of war. 

September 28th. We passed the small town of Luxan, where 
there is a wooden bridge over the river a most unusual conve- 
nience in this country. We passed also Areco. The plains 



124 PAMPAS. [CHAP. vn. 

appeared level, but were not so in fact ; for in various places the 
horizon was distant. The estancias are here wide apart ; for 
.here is little good pasture, owing to the land being covered by 
beds either of an acrid clover, or of the great thistle. The 
latter, well known from the animated description given by Sir 
F. Head, were at this time of the year two-thirds grown ; in 
some parts they were as high as the horse's back, but in others 
they had not yet sprung up, and the ground was bare arid dusty 
as on a turnpike-road. The clumps were of the most brilliant 
green, and they made a pleasing miniature-likeness of broken 
forest land. When the thistles are full grown, the great beds 
are impenetrable, except by a few tracks, as intricate as those in 
a labyrinth. These are only known to the robbers, who at this 
season inhabit them, and sally forth at night to rob and cut 
throats with impunity. Upon asking at a house whether rob- 
bers were numerous, I was answered, " The thistles are not up 
yet ;" the meaning of which reply was not at first very obvious. 
There is little interest in passing over these tracts, for they are 
inhabited by few animals or birds, excepting the bizcacha and 
its friend the little owl. 

The bizcacha* is well known to form a prominent feature in 
the zoology of the Pampas. It is found as far south as the Rio 
Negro, in lat. 41, but not beyond. It cannot, like the agouti, 
subsist on the gravelly and desert plains of Patagonia, but pre- 
fers a clayey or sandy soil, which produces a different and more 
abundant vegetation. Near Mendoza, at the foot of the Cordil- 
lera, it occurs in close neighbourhood with the allied alpine spe- 
cies. It is a very curious circumstance in its geographical dis- 
tribution, that it has never been seen, fortunately for the inha- 
bitants of Banda Oriental, to the eastward of the river Uru- 
guay : yet in this province there are plains which appear admira- 
bly adapted to its habits. The Uruguay has formed an insuper- 
able obstacle to its migration ; although the broader barrier oi 
the Parana lias been passed, and the bizcacha is common in 
Entre Rios, the province between these two great rivers. Near 
Buenos Ayres these animals are exceedingly common. Their 

* The bizcacha (Lagostomus trichodactylus) somewhat resembles a large 
rabbit, but with bigger gnawing teeth and a long tail : it has, however, only 
three toes behind, like the agouti. During the last three or four years the 
skins of these animals have been sent to England for the sake of the fur. 



1833.] THE BIZCACHA. 



most favourite resort appears to be those parts of the plain which 
during one half of the year are covered with giant thistles, to 
the exclusion of other plants. The Gauchos affirm that it lives 
on roots ; which, from the great strength of its gnawing teeth, 
and the kind of places frequented by it, seems probable. In the 
evening the bizcachas come out in numbers, and quietly sit at 
the mouths of their burrows on their haunches. At such times 
they are very tame, and a man on horseback passing by seems 
only to present an object for their grave contemplation. They 
run very awkwardly, and when running out of danger, from 
their elevated tails and short front legs, much resemble great 
rats. Thein flesh, when cooked, is very white and good, but it 
is seldom used. 

The bizcacha has one very singular habit ; namely, dragging 
every hard object to the mouth of its burrow : around each 
group of holes many bones of cattle, stones, thistle-stalks, hard 
lumps of earth, dry dung, &c., are collected into an irregular 
heap, which frequently amounts to as much as a wheelbarrow 
would contain. I was credibly informed that a gentleman, when 
riding on a dark night, dropped his watch ; he returned in the 
morning, and by searching the neighbourhood of every bizcacha 
hole on the line of road, as he expected, he soon found it. This 
habit of picking up whatever may be lying on the ground any 
where near its habitation, must cost much trouble. For what 
purpose it is done, I am quite unable to form even the most re- 
mote conjecture : it cannot be for defence, because the rubbish 
is chiefly placed above the mouth of the burrow, which enters 
the ground at a very small inclination. No doubt there must 
exist some good reason ; but the inhabitants of the country are 
quite ignorant of it. The only fact which I know analogous to 
it, is the habit of that extraordinary Australian bird, the Calo- 
dera maculata, which makes an elegant vaulted passage of twigs 
for playing in, and which collects near the spot, land and sea- 
shells, bones, and the feathers of birds, especially brightly co- 
loured ones. Mr. Gould, who has described these facts, in- 
forms me, that the natives, when they lose any hard object, 
search the playing passages, and he has known a tobacco-pipe 
thus recovered. 

The little owl (Athene cuuicularia), which has been so often 



126 PAMPAS. [CHAP. vn. 

mentioned, on the plains of Buenos Ayres exclusively inhabits 
the holes of the bizcacha ; but in Banda Oriental it is its own 
workman. During the open day, but more especially in the 
evening, these birds may be seen in every direction standing fre- 
quently by pairs on the hillock near their burrows. If disturbed 
they either enter the hole, or, uttering a shrill harsh cry, move 
with a remarkably undulatory flight to a short distance, and 
then turning round, steadily gaze at their pursuer. Occasionally 
in the evening they may be heard hooting. I found in the sto- 
machs of two which I opened the remains of mice, and I one 
day saw a small snake killed and carried away. It is said that 
snakes are their common prey during the daytime. - 1 may here 
mention, as showing on what various kinds of food owls subsist, 
that a species killed among the islets of the Chonos Archipelago, 
had its stomach full of good-sized crabs. In India* there is a 
fishing genus of owls, which likewise catches crabs. 

In the evening we crossed the Eio Arrecife on a simple raft 
made of barrels lashed together, and slept at the post-house on 
the other side. 1 this day paid horse-hire for thirty-one leagues ; 
and although the sun was glaring hot I was but little fatigued. 
When Captain Head talks of riding fifty leagues a day, I do 
not imagine the distance is equal to 150 English miles. At all 
events, the thirty-one leagues was only 76 miles in a straight 
line, and in an open country I should think four additional miles 
for turnings would be a sufficient allowance. 

29th and 30th. We continued to ride over plains of the 
same character. At San Nicolas I first saw the noble river of 
the Parana. At the foot of the cliff on which the town stands, 
some large vessels were at anchor. Before arriving at Rozario, 
we crossed the Saladillo, a stream of fine clear running water, 
but too saline to drink. Eozario is a large town built on a dead 
level plain, which forms a cliff about sixty feet high over the 
Parana. The river here is very broad, with many islands, which 
are low and wooded, as is also the opposite shore. The view 
would resemble that of a great lake, if it were not for the linear- 
shaped islets, which alone give the idea of running water. The 
cliffs are the most picturesque part ; sometimes they are abso- 
lutely perpendicular, and of a red colour ; at other times in large

1833.] RIO TERCERO. 127 

broken masses, covered with cacti and mimosa-trees.. The real 
grandeur, however, of an immense river like this, is derived 
from reflecting how important a means of communication and 
commerce it forms between one nation and another ; to what a 
distance it travels ; and from how vast a territory it drains the 
great body of fresh water which flows past your feet. 

For many leagues north and south of San Nicolas and Roza- 
rio, the country is really level. Scarcely anything which travel- 
lers have written about its extreme flatness, can be considered as 
exaggeration. Yet I could never find a spot where, by slowly 
turning round, objects were not seen at greater distances in some 
directions than in others ; and this manifestly proves inequality 
in the plain. At sea, a person's eye being six feet above the 
surface of the water, his horizon is two miles and four-fifths dis- 
tant. In like manner, the more level the plain, the more nearly 
does the horizon approach within these narrow limits ; and this, 
in my opinion, entirely destroys that grandeur which one would 
have imagined that a vast level plain would have possessed. 

October 1st. We started by moonlight and arrived at the 
Rio Tercero by sunrise. This river is also called the Saladillo, 
and it deserves the name, for the water is brackish. I stayed 
here the greater part of the day, searching for fossil bones. 
Besides a perfect tooth of the Toxodon, and many scattered 
bones, 1 found two immense skeletons near each other, projecting 
in bold relief from the perpendicular cliff of the Parana. They 
were, however, so completely decayed, that I could only bring 
away small fragments of one of the great molar teeth ; but these 
are sufficient to show that the remains belonged to a Mastodon, 
probably to the same species with that, which formerly must have 
.nhabited the Cordillera in Upper Peru in such great numbers. 
The men who took me in the canoe, said they had long known 
of these skeletons, and had often wondered how they had got 
there : the necessity of a theory being felt, they came to the 
conclusion that, like the bizcacha, the mastodon was formerly a 
burrowing animal ! In the evening we rode another stage, and 
crossed the Monge, another brackish stream, bearing the dregs 
of the washings of the Pampas. 

October 2nd. We passed through Corunda, which, from the 
luxuriance of its gardens, was one of the prettiest villages I saw, 



128 ST. Fl. [CHAP. vn. 

From this, point to St. Fe the road is not very safe. The western 
side of the Parana northward, ceases to be inhabited ; and hence 
the Indians sometimes come down thus far, and waylay travellers. 
The nature of the country also favours this, for instead of a grassy 
plain, there is an open woodland, composed of low prickly 
mimosas. We passed some houses that had been ransacked and 
since deserted ; we saw also a spectacle, which my guides viewed 
with high satisfaction ; it was the skeleton of an Indian with the 
dried skin hanging on the bones, suspended to the branch of a 
tree. 

In the morning we arrived at St. Fe. I was surprised to 
observe how great a change of climate a difference of only three 
degrees of latitude between this place and Buenos Ayres had 
caused. This was evident fronr* the dress and complexion of the 
men from the increased size of the ombu-trees the number of 
new cacti and other plants and especially from the birds. In 
the course of an hour I remarked half-a-dozen birds, which I had 
never seen at Buenos Ayres. Considering that there is no natural 
boundary between the two places, and that the character of the 
country is nearly similar, the difference was much greater than I 
should have expected 

October 3rd and 4tk. I was confined for these two days to 
my bed by a headach. A good-natured old woman, who attended 
me, wished me to try many odd remedies. A common practice 
is, to bind an orange-leaf or a bit of black plaster to each temple : 
and a still more general plan is, to split a bean into halves, 
moisten them, and place one on each temple, where they will 
easily adhere. It is not thought proper ever to remove the beans 
or plaster, but to allow them to drop off; and sometimes, if a 
man, with patches on his head, is asked, what is the matter? he 
will answer, " I had a headach the day before yesterday." Many 
of the remedies used by the people of the country are ludicrously 
strange, but too disgusting to be mentioned. One of the least 
nasty is to kill and cut open two puppies and bind them on each 
side of a broken limb. Little hairless dogs are in great request 
to sleep at the feet of invalids. 

St. Fe is a quiet little town, and is kept clean and in good 
order. The governor, Lopez, was a common soldier at the time 
of the revolution ; but has now been seventeen years in power. 



1833.] GEOLOGY OF THE PAMPAS. 129 

This stability of government is owing to his tyrannical habits ; 
for tyranny seems as yet better adapted to these countries than 
republicanism. The governor's favourite occupation is hunting 
Indians : a short time since he slaughtered forty-eight, and sold 
the children at the rate of three or four pounds apiece. 

October 5th. We crossed the Parana to St. Fe Bajada, a 
town on the opposite shore. The passage took some hours, as 
the river here consisted of a labyrinth of small streams, separated 
by low wooded islands. I had a letter of introduction to an old 
Catalonian Spaniard, who treated me with the most uncommon 
hospitality. The Bajada b the capital of Entre Eios. In 1825 
the town contained 6000 inhabitants, and the province 30,000 ; 
yet, few as the inhabitants are, no province has suffered more from 
bloody and desperate revolutions. They boast here of repre- 
sentatives, ministers, a standing army, and governors : so it is no 
wonder that they have their revolutions. At some future day 
this must be one of the richest countries of La Plata. The soil 
is varied and productive ; and its almost insular form gives it 
two grand lines of communication by the rivers Parana and 
Uruguay. 

I was delayed here five days, and employed myself in ex- 
amining the geology of the surrounding country, which was very 
interesting. We here see at the bottom of the cliffs, beds contain- 
ing sharks' teeth and sea-shells of extinct species, passing above 
into an indurated marl, and from that into the red clayey earth 
of the Pampas, with its calcareous concretions and the bones of 
terrestrial quadrupeds. This vertical section clearly tells us of a 
large bay of pure salt-water, gradually encroached on, and at last 
converted into the bed of a muddy estuary, into which floating 
carcasses were swept. At Puuta Gorda, in Banda Oriental, I 
found an alternation of the Pampoean estuary deposit, with a 
limestone containing some of the same extinct sea-shells; and 
this shows either a change in the former currents, or more pro- 
bably an oscillation of level in the bottom of the ancient estuary. 
Until lately, my reasons for considering the Pampaean formation 
to be an estuary deposit were, its general appearance, its position at 
the mouth of the existing great river the Plata, and the presence 
of so many bones of terrestrial quadrupeds : but now Professoj 



130 ST. Ffi. [CHAP. vn. 

Ebrenberg has had the kindness to examine for me a little of the 
red earth, taken from low down in the deposit, close to the 
skeletons of the mastodon, and he finds in it many infusoria, 
partly salt-water and partly fresh-water forms, with the latter 
rather preponderating ; and therefore, as he remarks, the water 
must have been brackish. M. A. d'Orbigny found on the banks 
of the Parana, at the height of a hundred feet, great beds of an 
estuary shell, now living a hundred miles lower down nearer the 
sea ; and I found similar shells at a less height on the banks of 
the Uruguay : this shows that just before the Pampas was slowly 
elevated into dry land, the water covering it was brackish. 
Below Buenos Ayres there are upraised beds of sea-shells of 
existing species, which also proves that the period of elevation 
of the Pampas was within the recent period. 

In the Pampaean deposit at the Bajada I found the osseous armour 
of a gigantic armadillo-like animal, the inside of which, when the 
earth was removed, was like a great cauldron ; I found also teeth of 
the Toxodon and Mastodon, and one tooth of a Horse, in the same 
stained and decayed state. This latter tooth greatly interested 
me,* and 1 took scrupulous care in ascertaining that it had been 
embedded contemporaneously with the other remains ; for I was 
not then aware that amongst the fossils from Bahia Blanca there 
was a horse's tooth hidden in the matrix : nor was it then known 
with certainty that the remains of horses are common in North 
America. Mr. Lyell has lately brought from the United States 
a tooth of a horse ; and it is an interesting fact, that Professor 
Owen could find in no species, either fossil or recent, a slight 
but peculiar curvature characterizing it, until he thought of com- 
paring it with my specimen found here : he has named this 
American horse Equus curvidens. Certainly it is a marvellous 
fact in the history of the Mammalia, that in South America a 
native horse should have Kved and disappeared, to be succeeded 
in after ages by the countless herds descended from the few 
introduced with the Spanish colonists !

mastodon, possibly of an elephant,']' and of a hollow-horned

ruminant, discovered by MM. Lund and Clausen in the caves of 
Brazil, are highly interesting facts with respect to the geo- 
graphical distribution of animals. At the present time, if we 
divide America, not by the Isthmus of Panama, but by the 
southern part of Mexico* in lat. 20, where the great table- land 
presents an obstacle to the migration of species, by affecting the 
climate, and by forming, with the exception of some valleys and 
of a fringe of low land on the coast, a broad barrier ; we shall 
then have the two zoological provinces of North and South 
America strongly contrasted with each other. Some few species 
alone have passed the barrier, and may be considered as wander- 
ers from the south, such as the puma, opossum, kinkajou, and pec- 
cari. South America is characterized by possessing many peculiar 
gnawers, a family of monkeys, the llama, peccari, tapir, opossums, 
and, especially, several genera of Edentata, the order which in- 
cludes the sloths, ant-eaters, and armadillos. North America, 
on the other hand, is characterized (putting on one side a few 
wandering species) by numerous peculiar gnawers, and by four 
genera (the ox, sheep, goat, and antelope) of hollow-horned 
ruminants, of which great division South America is not known 
to possess a single species. Formerly, but within the period 
when most of the now existing shells were living, North 
America possessed, besides hollow-horned ruminants, the ele- 
phant, mastodon, horse, and three genera of Edentata, namely, 
the Megatherium, Megalonyx, and Mylodon. Within nearly this 
same periods (as proved by the shells' at Bahia Blanca) South 
America possessed, as we ha\e just seen, a mastodon, horse, 
hollow-horned ruminant, and the same three genera (as well as 
several others) of the Edentata. Hence it is evident that North 
and South America, in having within a late geological period 
these several genera in common, were much more closely related 
in the character of their terrestrial inhabitants than they now are. 

* This is the geographical division folio-wed by Lichtenstein, Swaiuson, 
Erichson, and Richardson. The section from Vera Cruz to Acapulco, given 
by Humboldt in the Polit. Essay on Kingdom of N. Spain, will show how 
immense a barrier the Mexican table-land forms. Dr. Richardson, in his 
admirable Report on the Zoology of N. America read before the Brit. Assoc. 
1836 (p. 157), talking of the identification of a Mexican animal with the 
Synetheres prehensilis, says, " We do not know with what propriety, but if 
correct, it is, if not a solitary instance, at least very nearly so, (if a rodent 
animal being common to North arid South America/ 



132 ST. Ffi. [CHAP. TII. 

The more I reflect on this case, the more interesting it appears : 
I know of no other instance where we can almost mark the 
period and manner of the splitting up of one great region into 
two well-characterized zoological provinces. The geologist, who 
is fully impressed with the vast oscillations of level which have 
affected the earth's crust within late periods, will not fear to 
speculate on the recent elevation of the Mexican platform, or, 
more probably, on the iccent submergence of land in the West 
Indian Archipelago, as the cause of the present zoological sepa- 
ration of North and South America. The South American 
character of the West Indian mammals * seems to indicate that 
this archipelago was formerly united to the southern continent, 
and that it has subsequently been an area of subsidence. 

When America, and especially North America, possessed its 
elephants, mastodons, horse, and hollow-horned ruminants, it was 
much more closely related in its zoological characters to the 
temperate parts of Europe and Asia than it now is. As the 
remains of these genera are found on both sides of Behring's 
Straitsf and on the plains of Siberia, we are led to look to the 
north-western side of North America as the former point of 
communication between the Old and so-called New World. And 
as so many species, both living and extinct, of these same genera 
inhabit and have inhabited the Old World, it seems most probable 
that the North American elephants, mastodons, horse, and hollovv- 
liorned ruminants migrated, on land since submerged near Beh- 
ring's Straits, from Siberia into North America, and thence, on 
land since submerged in the West Indies, into South America, 
where for a time they mingled with the forms characteristic of 
that southern continent, and have since become extinct. 

While travelling through the country, I received several vivid 
descriptions of the effects of a late great drought ; and the 
account of this may throw some light on the cases where vast

numbers of animals of all kinds have been embedded together. 
The period included between the years 1827 and 1830 is called 
tlie"gran seco," or the great drought. During this time so 
little rain fell, that the vegetation, even to the thistles, failed ; 
the brooks were dried up, and the whole country assumed the 
appearance of a dusty high road. This was especially the case 
in the northern part of the province of Buenos Ayres and the 
southern part of St. Fe. Very great numbers of birds, wild 
animals, cattle, and horses perished from the want of food and 
water. A man told me that the deer* used to come into his 
courtyard to the well, which he had been obliged to dig to supply 
nis own family with wafer ; and that the partridges had hardly 
strength to fly away when pursued. The lowest estimation of 
the loss of cattle in the province of Buenos Ayres alone, was 
taken at one million head. A proprietor at San Pedro had pre- 
viously to these years 20,000 cattle ; at the end not one re- 
mained. San Pedro is situated in the middle of the finest 
country ; and even now abounds again with animals ; yet, during 
the latter part of the '* gran seco," live cattle were brought in 
vessels for the consumption of the inhabitants. The animals 
roamed from their estancias, and, wandering far southward, were 
mingled together in such multitudes, that a government com- 
mission was sent from Buenos Ayres to settle the disputes of the 
owners. Sir Woodbine Parish informed me of another and very 
curious source of dispute ; the ground being so long dry, such 
quantities of dust were blown about, that in this open country 
the landmarks became obliterated, and people could not tell the 
limits of their estates. 

I was informed by an eyewitness that the cattle in herds of 
thousands rushed into the Parana, and being exhausted by hunger 
they were unable to crawl up the muddy banks, and thus were 

* In Capt. Owen's Surveying Voyage (vol. ii. p. 274) there is a curioue 
account of the effects of a drought on the elephants, at Benguela (west coast 
of Africa). " A number of these animals had some time since entered the 
town, in a body, to possess themselves of the wells, not being able to procure 
any water in the country. The inhabitants mustered, when a desperate 
conflict ensued, which terminated in the ultimate discomfiture of the in- 
vaders, but not until they had killed one man, and wounded several others." 
The to-wn is said to have a population of nearly three thousand ! Dr. Mal- 
colmson informs me, that during a great drought in India the wild animals 
entered the tents of some troops at Ellore, and that a hare drank out of a 
vessel held by the adjutant of the regiment.

drowned. The arm of the river which runs by San Pedro was 
so full of putrid carcasses, that the master of a vessel told me 
that the smell rendered it quite impassable. Without doubt 
several hundred thousand animals thus perished in the river : 
their bodies when putrid were seen floating down the stream ; 
and many in all probability were deposited in the estuary of the 
Plata. All the small rivers became highly saline, and this caused 
the death of vast numbers in particular spots ; for when an animal 
drinks of such water it does not recover. Azara describes* the 
fury of the wild horses on a similar occasion, rushing into the 
marshes, those which arrived first being overwhelmed and 
crushed by those which followed. He adds that more than once 
he has seen the carcasses of upwards of a thousand wild horses 
thus destroyed. I noticed that the smaller streams in the Pampas 
were paved with a breccia of bones, but this probably is the 
effect of a gradual increase, rather than of the destruction at 
any one period. Subsequently to the drought of 1827 to '32, 
a very rainy season followed, which caused great floods. Hence 
it is almost certain that some thousands of the skeletons were 
buried by the deposits of the very next year. What would be 
the opinion of a geologist, viewing such an enormous collection 
of bones, of all kinds of animals and of all ages, thus embedded 
in one thick earthy mass ? Would he not attribute it to a flood 
having swept over the surface of the land, rather than to the 
common order of things ?j 

October \2th. I had intended to push my excursion further, 
but not being quite well, I was compelled to return by a 
balandra, or one-masted vessel of about a hundred tons' burden, 
which was bound to Buenos Ayres. As the weather was not 
fair, we moored early in the day to a branch of a tree on one ol 
the islands. The Parana is full of islands, which undergo a con- 
stant round of decay and renovation. In the memory of the 
master several large ones had disappeared, and others again had 
been formed and protected by vegetation. They are composed 
of muddy sand, without even the smallest pebble, and were then

t These droughts to a certain degree seem to be almost periodical ; 1 
vas told the dates of several others, and the intervals were about fifteen 
years. 



1833.] HABITS OF THE JAGUAR. 135 

about four feet above the level of the river ; but during the 
periodical floods they are inundated. They all present one cha- 
racter ; numerous willows arid a few other trees are bound to- 
gether by a great variety of creeping plants, thus forming a thick 
jungle. These thickets afford a retreat for capybaras and 
jaguars. The fear of the latter animal quite destroyed all plea- 
sure in scrambling through the woods. This evening I had not 
proceeded a hundred yards, before finding indubitable signs of 
the recent presence of the tiger, I was obliged to come back. 
On every island there were tracks ; and as on the former excursion 
" el rastro de los Indios" had been the subject of conversation, so 
in this was " el rastro del tigre." 

The wooded banks of the great rivers appear to be the favourite 
haunts of the jaguar ; but south of the Plata, I was told that they 
frequented the reeds bordering lakes : wherever they are, they seem 
to require water. Their common prey is the capybara, so that 
it is generally said, where capybaras are numerous there is little 
danger from the jaguar. Falconer states that near the southern 
side of the mouth of the Plata there are many jaguars, and that 
they chiefly live on fish ; this account I have heard repeated. 
On the Parana they have killed many wood-cutters, and have 
even entered vessels at night. There is a man now living in the 
Bajada, who, coming up from below when it was dark, was seized 
on the deck ; he escaped, however, with the loss of the use of 
one arm. When the floods drive these animals from the islands, 
they are most dangerous. I was told that a few years since a 
very large one found its way into a church at St. Fe : two padres 
entering one after the other were killed, and a third, who came 
to see what was the matter, escaped with difficulty. The beast 
was destroyed by being shot from a corner of the building which 
was unroofed. They commit also at these times great ravages 
among cattle and horses. It is said that they kill their prey by 
breaking their necks. If driven from the carcass, they seldom 
return to it. The Gauchos say that the jaguar, when wandering 
about at night, is much tormented by the foxes yelping as they 
follow him. This is a curious coincidence with the fact which is 
generally affirmed of the jackals accompanying, in a similarly 
officious manner, the East Indian tiger. The jaguar is a noisy 
animal, roaring much by night, and especially before bad weather. 
10 



136 RIO PARANA. [CHAP. vn. 

One day, when hunting on the banks of the Uruguay, I was 
shown certain trees, to which these animals constantly recur for 
the purpose, as it is said, of sharpening their claws. I saw three 
well-known trees ; in front, the bark was worn smooth, as if by 
the breast of the animal, and on each side there were deep 
scratches, or rather grooves, extending in an oblique line, nearly 
a yard in length. The scars were of different ages. A common 
method of ascertaining whether a jaguar is in the neighbourhood 
is to examine these trees. I imagine this habit of the jaguar is 
exactly similar to one which may any day be seen in the common 
cat, as with outstretched legs and exserted claws it scrapes the 
leg of a chair ; and I have heard of young fruit-trees in an 
orchard in England having been thus much injured. Some such 
habit must also be common to the puma, for on the bare hard soil 
of Patagonia I have frequently seen scores so deep that no other 
animal could have made them. The object of this practice is, I 
believe, to tear off the ragged points of their claws, and not, as 
the Gauchos think, to sharpen them. The jaguar is killed, 
without much difficulty, by the aid of dogs baying and driving 
him up a tree, where he is despatched with bullets. 

Owing to bad weather we remained two days at our mcorings. 
Our only amusement was catching fish for our dinner: there 
were several kinds, and all good eating. A fish called the 
" armado" (a Silurus) is remarkable from a harsh grating noise 
which it makes when caught by hook and line, and which can be 
distinctly heard when the fish is beneath the water. This same fish 
has the power of firmly catching hold of any object, such as the 
blade of an oar or the fishing-line, with the strong spine both of 
its pectoral and dorsal fin. In the evening the weather was quite 
tropical, the thermometer standing at 79. Numbers of fireflies 
were hovering about, and the musquitoes were very troublesome. 
I exposed my hand for five minutes, and it was soon black with 
them ; I do not suppose there could have been less than fifty, all 
busy sucking. 

October 15th. We got under way and passed Punta Gorda, 
where there is a colony of tame Indians from the province of 
Missiones. We sailed rapidly down the current, but before 
sunset, from a silly fear of bad weather, we brought-to in a nar- 
row arm of the river. I took the boat and rowed some distance 



1833.] THE SCISSOR-BEAK. 137 

up this creek. It was very narrow, winding, and deep ; on each 
side a wall thirty or forty feet high, formed by trees intwined 
with creepers, gave to the canal a singularly, gloomy appearance, 
I here saw a very extraordinary bird, called the Scissor-beak 
(Rhynchops nigra). It has short legs, web feet, extremely long- 
pointed wings, and is of about the size of a tern. The beak is 




flattened laterally, that is, in a plane at right angles to that of a 
spoonbill or duck. It is as flat and elastic as an ivory paper- 
cutter, and the lower mandible, differently from every other bird, 
is an inch and a half longer than the upper. In a lake near 
Maldonado, from which the water had been nearly drained, and 
which, in consequence, swarmed with small fry, I saw several of 
these birds, generally in small flocks, flying rapidly backwards 
and forwards close to the surface of the lake. They kept their 
bills wide open, and the lower mandible half buried in* the 
water. Thus skimming the surface, they ploughed it in their 
course : the water was quite smooth, and it formed a most curious 
spectacle to behold a flock, each bird leaving its narrow wake on 
the mirror-like surface. In their flight they frequently twist 
about with extreme quickness, and dexterously manage with their 
projecting lower mandible to plough up small fish, which are 
secured by the upper and shorter half of their scissor-like bills. 
This fact I repeatedly saw, as, like swallows, they continued to 
fly backwards and forwards close before me. Occasionally when 
leaving the surface of the water their flight was wild, irregular, 
and rapid ; they then uttered loud harsh cries. When these 
birds are fishing, the advantage of the long primary feathers of 
their wings, in keeping them dry, is very evident. When thus 
employed, their forms resemble the symbol by which many artists 
represent marine birds. Their tails are much used in steering 
their irregular course. 



138 RIO PARANA. [CHAP. vn. 

These birds are common far inland along the course of the 
Rio Parana ; it is said that they remain here during the whole 
year, and breed in the marshes. During the day they rest in 
flocks en the grassy plains, at some distance from the water. 
Being at anchor, as I have said, in one of the deep creeks be- 
tween the islands of the Parana, as the evening drew to a close, 
one of these scissor-beaks suddenly appeared. The water was 
quite still, and many little fish were rising. The bird continued 
for a long time to skim the surface, flying in its wild and irre- 
gular manner up and down the narrow canal, now dark with the 
growing night and the shadows of the overhanging trees. At 
Monte Video, I observed that some large flocks during the day 
remained on the mud-banks at the head of the harbour, in the 
same manner as on the grassy plains near the Parana ; and every 
evening they took flight seaward. From these facts I suspect 
that the Rhynchops generally fishes by night, at which time many 
of the lower animals come most abundantly to the surface. M. 
Lesson states that he has seen these birds opening the shells of 
the mactrae buried in the sand-banks on the coast of Chile : 
from their weak bills, with the lower mandible so much project- 
ing, their short legs and long wings, it is very improbable that 
this can be a general habit. 

In our course down the Parana, I observed only three other 
birds, whose habits are worth mentioning. One is a small king- 
fisher (Ceryle Americana) ; it has a longer tail than the European 
species, and hence does not sit in so stiff and upright a position. 
Its flight also, instead of being direct and rapid, like the course 
of an arrow, is weak and undulatory, as among the soft-billed 
birds. It utters a low note, like tiie clicking together of two 
small stones. A small green parrot (Conurus murinus), with a 
grey breast, appears to prefer the tall trees on the islands to any 
other situation for its building-place. A number of nests are 
placed so close together as to form one great mass of sticks. 
These parrots always live in flocks, and commit great ravages on 
the corn-Selds. I was told that near Colonia 2500 were killed 
in the course of one year. A bird with a forked tail, terminated 
by two long feathers (Tyrannus savana), and named by the 
Spaniards scissor-tail, is very common near Buenos Ayres : it 
commonly sits on a branch of the ombu tree, near a house, and 



1833.] RIO PARANA. 139 

thence takes a short flight in pursuit of insects, and returns to 
the same spot. When on the wing it presents in its manner of 
flight and general appearance a caricature-likeness of the com- 
mon swallow. It has the power of turning very shortly in the 
air, and in so doing opens and shuts its tail, sometimes in a 
horizontal or lateral and sometimes in a vertical direction, just 
like a pair of scissors. 

October IQth. Some leagues below Rozario, the western 
shore of the Parana is bounded by perpendicular cliffs, which 
extend in a long line to below San Nicolas ; hence it more 
resembles a sea-coast than that of a fresh-water river. It is 
a great drawback to the scenery of the Parana, that, from the soft 
nature of its banks, the water is very muddy. The Uruguay, 
flowing through a granitic country, is much clearer; and where 
the two channels unite at the head of the Plata, the waters 
may for a long distance be distinguished by their black and red 
colours. In the evening, the wind being not quite fair, as usual 
we immediately moored, and the next day, as it blew rather 
freshly, though with a favouring current, the master was much 
too indolent to think of starting. At Bajada, he was described 
to me as " hombre muy aflicto " a man always miserable to get 
on ; but certainly he bore all delays with admirable resignation. 
He was an old Spaniard, and had been many years in this 
country. He professed a great liking to the English, but stoutly 
maintained that the battle of Trafalgar was merely won by the 
Spanish captains having been all bought over ; and that the only 
really gallant action on either side was performed by the Spanish 
admiral. It struck me as rather characteristic, that this man 
should prefer his countrymen being thought the worst of traitors, 
rather than unskilful or cowardly. 

18th and 19th. We continued slowly te sa ; l down the noble 
stream : the current helped us but little. We met, during our 
descent, very few vessels. One of the best gifts of nature, in so 
grand a channel of communication, seems here wilfully thrown 
away a river in which ships might navigate from a temperate 
country, as surprisingly abundant in certain productions as desti- 
tute of others, to another possessing a tropical climate, and a soil 
which, according to the best of judges, M. Bonpland, is perhaps 
unequalled in fertility in any part of the world. How different 



140 REVOLUTION AT BUENOS AYRES. [CHAP. VH. 

would have been the aspect of this river if English colonists had 
by good fortune first sailed up the Plata ! What noble towns 
would now have occupied its shores ! Till the death of Francia, the 
Dictator of Paraguay, these two countries must remain distinct, as 
if placed on opposite sides of the globe. And when the old 
bloody-minded tyrant is gone to his long account, Paraguay will 
be torn by revolutions, violent in proportion to the previous un- 
natural calm. That country will have to learn, like every other 
South American state, that a republic cannot succeed till it con- 
tains a certain body of men imbued with the principles of justice 
and honour. 

October 20th. Being arrived at the mouth of the Parana, and 
as I was very anxious to reach Buenos Ayres, I went on shore at 
Las Conchas, with the intention of riding there. Upon landing, 
I found to my great surprise that I was to a certain degree a 
prisoner. A violent revolution having broken out, all the ports 
were laid under an embargo. I could not return to my vessel, 
and as for going by land to the city, it was out of the question. 
After a long conversation with the commandant, I obtained per- 
mission to go the next day to General Rolor, who commanded a 
division of the rebels on this side the capital. In the morning 
I rode to the encampment. The general, officers, and soldiers, 
all appeared, and I believe really were, great villains. The 
general, the very evening before he left the city, voluntarily went 
to the Governor, and with his hand to his heart, pledged his word 
of honour that he at least would remain faithful to the last. The 
genera] told me that the city was in a state of close blockade, and 
that all he could do was to give me a passport to the commander- 
in-chief of the rebels at Quilmes. We had therefore to take a 
great sweep round the city, and it was with much difficulty that 
we procured horses. My reception at the encampment was quite 
civil, but I was told it was impossible that I could be allowed to 
enter the city. I was veiy anxious about this, as I anticipated 
the Beagle's departure from the Rio Plata earlier than it took 
place. Having mentioned, however, General Rosas's obliging 
kindness to me when at the Colorado, magic itself could not 
have altered circumstances quicker than did this conversation. I 
was instantly told that though they could not give me a passport, 
if I chose to leave my guide and horses, I might pass their sen- 



1833.] REVOLUTION AT BUENOS AYRES. 141 

tinels. I was too glad to accept of this, and an officer was sent 
with me to give directions that I should not be stopped at the 
bridge. The road for the space of a league was quite deserted. 
I met one party of soldiers, who were satisfied by gravely look- 
ing at an old passport: and at length I was not a little pleased to 
find myself within the city. 

This revolution was supported by scarcely any pretext of 
grievances : but in a state which, in the course of nine months 
'from February to October, 1820), underwent fifteen changes in 
its government each governor, according to the constitution, 
being elected for three years it would be very unreasonable to 
ask for pretexts. In this case, a party of men who, being at- 
tached to Rosas, were disgusted with the governor Balcarce to 
the number of seventy left the city, and with the cry of Rosas 
the whole country took arms. The city was then blockaded, no 
provisions, cattle or horses, were allowed to enter ; besides this, 
there was only a little skirmishing, and a few meu daily killed. 
The outside party well knew that by stopping the supply of meat 
they would certainly be victorious. General Rosas could not have 
known of this rising ; but it appears to be quite consonant with 
ihe plans of his party. A year ago he was elected governor, but 
he refused it, unless the Sala would also confer on him extra- 
ordinary powers. This was refused, and since then his party 
have shown that no other governor can keep his place. The 
warfare on both sides was avowedly protracted till it was possible 
to hear from Rosas. A note arrived a few days after I left 
Buenos Ayres, which stated that the General disapproved of 
peace having been broken, but that he thought the outside party 
had justice on their side. On the bare reception of this, the 
Governor, ministers, and part of the military, to the number of 
some hundreds, fled from the city. The rebels entered, elected a 
new governor, and were paid for their services to the number of 
5500 men. From these proceedings, it was clear that Rosas 
ultimately would become the dictator : to the term king, the 
people in this, as in other republics, have a particular dislike. 
Since leaving South America, we have heard that Rosas has been 
elected, with powers and for a time altogether opposed to the 
constitutional principles of the republic.

BANDA ORIENTAL AND PATAGONIA. 

HAVING been delayed for nearly a fortnight in the city, I was 
glad to escape on board a packet bound for Monte Video. A 
town in a state of blockade must always be a disagreeable place 
of residence ; in this case moreover there were constant appre- 
hensions from robbers within. The sentinels were the worst of 
all ; for, from their office and from having arms in their hands, 
they robbed with a degree of authority which other men could 
not imitate. 

Our passage was a very long and tedious one. The Plata 
looks like a noble estuary on the map ; but is in truth a poor 
affair. A wide expanse of muddy water has neither grandeur nor 
beauty. At one time of the day, the two shores, both of which 
are extremely low, could just be distinguished from the deck. 
On arriving at Monte Video I found that the Beagle would not sail 
for some time, so I prepared for a short excursion in this part of 
Banda Oriental. Everything which I have said about the country 
near Maldonado is applicable to M. Video ; but the land, with the 
one exception of the Green Mount, 450 feet high, from which it 
takes its name, is far more level. Very little of the undulating 
grassy plain is enclosed ; but near the town there are a few hedge- 
banks, covered with agaves, cacti, and fennel. 

November 14th. We left Monte Video in the afternoon. I 
intended to proceed to Colonia del Sacramiento, situated on the 
northern bank of the Plata and opposite to Buenos Ayres, and 
thence, following up the Uruguay, to the village of Mercedes on 



1833.] BANDA ORIENTAL. 143 

the Rio Negro (one of the many rivers of this name in South 
America), and from this point to return direct to Monte Video. 
We slept at the house of my guide at Canelones. In the morning 
we rose early, in the hopes of being able to ride a good distance ; 
but it was a vain attempt, for all the rivers were flooded. We 
passed in boats the streams of Canelones, St. Lucia, and San Jose, 
and thus lost much time. On a former excursion I crossed the 
Lucia near its mouth, and I was surprised to observe how easily 
our horses, although not used to swim, passed over a width of at 
least six hundred yards. On mentioning this at Monte Video, I 
was told that a vessel containing some mountebanks and their 
horses, being wrecked in the Plata, one horse swam seven miles 
to the shore. In the course of the day I was amused by the dex- 
terity with which a Gaucho forced a restive horse to swim a 
river. He stripped offhis clothes, and jumping on its back, rode 
into the water till it was out of its depth ; then slipping off over 
the crupper, he caught hold of the tail, and as often as the horse 
turned round, the man frightened it back by splashing water in 
its face. As soon as the horse touched the bottom on the other 
side, the man pulled himself on, and was firmly seated, bridle in 
hand, before the horse gained the bank. A naked man on a 
naked horse is a fine spectacle ; I had no idea how well the two 
animals suited each other. The tail of a horse is a very useful 
appendage ; I have passed a river in a boat with four people in 
it, which was ferried across in the same way as the Gaucho. If 
a man arid horse have to cross a broad river, the best plan is for 
the man to catch hold of the pommel or mane, and help himself 
with the other arm. 

We slept and stayed the following day at the post of Cufre. In 
the evening the postman or letter-carrier arrived. He was a day 
after his time, owing to the Rio Rozario being flooded. It 
would not, however, be of much consequence ; for, although he 
had passed through some of the principal towns in Banda 
Oriental, his luggage consisted of two letters ! The view from 
the house was pleasing ; an undulating green surface, with dis- 
tant glimpses of the Plata. I find that I look at this province 
with very different eyes from what I did upon my first arrival. I 
recollect I then thought it singularly level ; but now, after gal- 
loping over the Pampas, my only surprise is, what could havo 



144 BAND A ORIENTAL. [CHAP. vm. 

induced me ever to have called it level. The country is a series 
of undulations, in themselves perhaps not absolutely great, but, as 
compared to the plains of St. Fe, real mountains. From these 
inequalities there is an abundance of small rivulets, and the turf 
is green and luxuriant 

November 17th. We crossed the Rozario, which was deep 
and rapid, and passing the village of Colla, arrived at mid-day 
at Colonia del Sacramiento. The distance is twenty leagues, 
through a country covered with fine grass, but poorly stocked 
with cattle or inhabitants. I was invited to sleep at Colonia, 
and to accompany on the following day a gentleman to his estan- 
cia, where there were some limestone rocks. The town is built 
on a stony promontory something in the same manner as at 
Monte Video. It is strongly fortified, but both fortifications 
and town suffered much in the Brazilian war. It is very an- 
cient ; and the irregularity of the streets, and the surrounding 
groves of old orange and peach trees, gave it a pretty appear- 
ance. The church is a curious ruin ; it was used as a powder- 
magazine, and was struck by lightning in one of the ten thousand 
thunder-storms of the Rio Plata. Two-thirds of the building 
were blown away to the very foundation ; and the rest stands a 
shattered and curious monument of the united powers of light- 
ning and gunpowder. In the evening I wandered about the 
half-demolished walls of the town. It was the chief seat of the 
Brazilian war; a war most injurious to this country, not so 
much in its immediate effects, as in being the origin of a multi- 
tude of generals and all other grades of officers. More generals 
are numbered (but not paid) in the United Provinces of La 
Plata than in the United Kingdom of Great Britain. These 
gentlemen have learned to like power, and do not object to a 
little skirmishing. Hence there are many always on the watch 
to create disturbance and to overturn a government which as 
yet has never rested on any stable foundation. I noticed, how- 
ever, both here and in other places, a very general interest in 
the ensuing election for the President ; and this appears a good 
sign for the prosperity of this little country. The inhabitants 
do not require much education in their representatives ; I heard 
some men discussing the merits of those for Colonia ; and it was 
said that, " although they were not men of business, they could 



1833.] CURIOUS BREED OF OXEN. 145 

nil sign their names:" with this they seemed to think every 
reasonable man ought to be satisfied. 

18th. Rode with my host to his estancia, at the Arroyo do 
San Juan. In the evening we took a ride round the estate : it 
contained two square leagues and a half, and was situated in 
what is called a rincon ; that is, one side was fronted by the 
Plata, and the two others guarded by impassable brooks. There 
was an excellent port for little vessels, and an abundance of 
small wood, which is valuable as supplying fuel to Buenos Ayres. 
I was curious to know the value of so complete an estancia. Of 
cattle there were 3000, and it would well support threo or four 
times that number; of mares feOO, together with 150 broken- in 
horses, and 600 sheep. There was plenty of water and lime- 
stone, a rough house, excellent corrals, and a peach orchard. 
For all this he had been offered 2000/., and he only wanted 500/. 
additional, and probably would sell it for less. The chiel 
trouble with an estancia is driving the cattle twice a week to a 
central spot, in order to make them tame, and to count them. 
This latter operation would be thought difficult, where there are 
ten or fifteen thousand head together. It is managed on the 
principle that the cattle invariably divide themselves into little 
troops of from forty to one hundred. Each troop is recognised 
by a few peculiarly marked animals, and its number is known : 
so that, one being lost out of ten thousand, it is perceived by its 
absence from one of the tropillas. During a stormy night the 
cattle all mingle together ; but the next morning the tropillas 
separate as before ; so that each animal must know its fellow 
out of ten thousand others. 

On two occasions I met with in this province some oxen of a 
very curious breed, called nata or niata. They appear exter- 
nally to hold nearly the same relation to other cattle, which bull 
or pug dogs do to other dogs. Their forehead is very short and 
broad, with the nasal end turned up, and the upper lip much 
drawn back ; their lower jaws project beyond the upper, and 
have a corresponding upward curve ; hence their teeth are always 
exposed. Their nostrils are seated high up and are very open ; 
their eyes project outwards. When walking they carry their 
heads low, on a short neck ; and their hinder legs are rather 
longer compared with the front legs than is usual. Their bare 



146 BANDA ORIENTAL. [CHAP. vin. 

teeth, their short heads, and upturned nostrils give them the 
most ludicrous self-confident air of defiance imaginable. 

Since my return, I have procured a skeleton head, through 
the kindness of my friend Captain Sulivan, R.N., which is now 
deposited in the College of Surgeons.* Don F. Muniz, of 
Luxan, has kindly collected for me all the information which he 
could respecting this breed. From his account it seems that 
about eighty or ninety years ago, they were rare and kept as 
curiosities at Buenos Ayres. The breed is universally believed 
to have originated amongst the Indians southward of the Plata ; 
and that it was with them the commonest kind. Even to this 
day, those reared in the provinces near the Plata show their less 
civilized origin, in being fiercer than common cattle, and in the 
cow easily deserting her first calf, if visited too often or molested. 
It is a singular fact that an almost similar structure to the ab- 
normal f one of the niata breed, characterizes, as I am informed 
by Dr. Falconer, that great extinct ruminant of India, the Siva- 
therium. The breed is very true ; and a niata bull and cow 
invariably produce niata calves. A niata bull with a common 
cow, or the reverse cross, produces offspring having an interme- 
diate character, but with the niata characters strongly displayed : 
according to Senor Muniz, there is the clearest evidence, con- 
trary to the common belief of agriculturists in analogous cases, 
that the niata cow when crossed with a common bull transmits 
her peculiarities more strongly than the niata bull when crossed 
with a common cow. When the pasture is tolerably long, the 
niata cattle feed with the tongue and palate a*; well as common 
cattle ; but during the great droughts, when so many animals 
perish, the niata breed is under a great disadvantage, and would 
be exterminated if not attended to ; for the common cattle, like 
horses, are able just to keep alive, by browsing with their lips on 
twigs of trees and reeds ; this the niatas cannot so well do, as 
their lips do not join, and hence they are found to perish before 
the common cattle. This strikes me as a good illustration of 
how little we are able to judge from the ordinary habits of life, 

* Mr. Waterhouse has drawn up a detailed description of this head, 
which I hope he will publish in some Journal.

November I9tk. Passing the valley of Las Vacas, we slept 
at a house of a North American, who worked a lime-kiln on 
the Arroyo de las Vivoras. In the morning we rode to a pro- 
jecting headland on the banks of the river, called Punta Gorda. 
On the way we tried to find a jaguar. There were plenty of 
fresh tracks, and we visited the trees, on which they are said to 
sharpen their claws ; but we did not succeed in disturbing one. 
From this point the Rio Uruguay presented to our view a noble 
volume of water. From the clearness and rapidity of the stream, 
its appearance was far superior to that of its neighbour the Pa- 
rana. On the opposite coast, several branches from the latter 
river entered the Uruguay. As the sun was shining, the two 
colours of the waters could be seen quite distinct. 

In the evening we proceeded on our road towards Mercedes 
on the Rio Negro. At night we asked permission to sleep at an 
estancia at which we happened to arrive. It was a very large 
estate, being ten leagues square, and the owner is one of the 
greatest landowners in the country. His nephew had charge of 
it, and with him there was a captain in the army, who the other 
day ran away from Buenos Ayres. Considering their station, 
their conversation was rather amusing. They expressed, as was 
usual, unbounded astonishment at the globe being round, and 
could scarcely credit that a hole would, if deep enough, come 
out on the other side. They had, however, heard of a country 
where there, were six months light and six of darkness, and where 
the inhabitants were very tall and thin ! They were curious 
about the price and condition of horses and cattle in England. 
Upon finding out we did not catch our animals with the lazo, 
they cried out, " Ah, then, you use nothing but the bolas :" the 
idea of an enclosed country was quite new to them. The cap- 
tain at last said, he had one question to ask me, which he should 
be very much obliged if I would answer with all truth. I trem- 
bled to think how deeply scientific it would be : it was, " Whe- 
ther the ladies of Buenos Ayres were not the handsomest in the 
world." I replied, like a renegade, " Charmingly so." He 
added, " I have one other question : Do ladies in any other 
part of the world wear such large combs ?" I solemnly assured 



148 BAND A ORIENTAL. [CHAP. vin. 

him that they did not. They were absolutely delighted. The 
captain exclaimed, " Look there ! a man who has seen half the 
world says it is the case ; we always thought so, but now we 
know it." My excellent judgment in combs and beauty pro- 
cured me a most hospitable reception ; the captain forced me to 
take his bed, and he would sleep on his recado. 

2lst. Started at sunrise, and rode slowly during the whole 
day. The geological nature of this part of the province was 
different from the rest, and closely resembled that of the Pam- 
pas. Tn consequence, *here were immense beds of the thistle, 
as well as of the cardoon : the whole country, indeed, may be 
called one great bed of these plants. The two sorts grow sepa- 
rate, each plant in company with its own kind. The cardoon is 
as high as a horse's back, but the Pampas thistle is often higher 
than the crown of the rider's head. To leave the road for a 
yard is out of the question ; and the road itself is partly, and in 
some cases entirely, closed. Pasture, of course there is none ; 
if cattle or horses once enter the bed, they are for the time com- 
pletely lost. Hence it is very hazardous to attempt to drive 
cattle at this season of the year ; for when jaded enough to face 
the thistles, they rush among them, and are seen no more. In 
these districts there are very few estancias, and these few are 
situated in the neighbourhood of damp valleys, where fortu- 
nately neither of these overwhelming plants can exist. As night 
came on before we arrived at our journey's end, we slept at a 
miserable little hovel inhabited by the poorest people. The ex- 
treme though rather formal courtesy of our host and hostess, 
considering their grade of life, was quite delightful. 

November 22nd. Arrived at an estancia on the Berquelo be- 
longing to a very hospitable Englishman, to whom I had a letter 
of introduction from my friend Mr. Lumb. I stayed here three 
days. One morning I rode with my host to the Sierra del Pedro 
Flaco, about twenty miles up the Rio Negro. Nearly the whole 
country was covered with good though coarse grass, which was 
as high as a horse's belly ; yet there were square leagues without 
a single head of cattle. The province of Banda Oriental, if well 
stocked, would support an astonishing number of animals ; at 
present the annual export of hides from Monte Video amounts 
to three hundred thousand ; and the home consumption, from 



1833.] HILL OF BEADS. 149 

waste, is very considerable. An estanciero told me that he often 
had to send large herds of cattle a long journey to a salting esta 
blishment, and that the tired beasts were frequently obliged to be 
killed and skinned ; but that he could never persuade the Gauchos 
to eat of them, and every evening a fresh beast was slaughtered for 
their suppers ! The view of the Rio Negro from the Sierra was 
more picturesque than any other which I saw in this province. 
The river, broad, deep and rapid, wound at the foot of a 
rocky precipitous cliff: a belt of wood followed its course, 
and the horizon terminated in the distant undulations of the 
turf-plain. 

When in this neighbourhood, I several times heard of the 
Sierra de las Cuentas : a hill distant many miles to the north- 
ward. 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 neck- 
laces and bracelets a taste, 1 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 circum- 
stances 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, 

* M. A. d'Orbigny has given nearly a similar account of these dogs, 
lorn. i. p. 1 75. 



150 BAND A ORIENTAL. [CHAP. vin. 

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 accustom- 
ing it to its future companions. 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 castrated ; 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 barking, and the sheep all 
close in his rear, as if round the oldest ram. These dogs are 
also easily taught to bring home the flock, at a certain hour in 
the evening. Their most troublesome fault, when young, is 
their desire of playing with the sheep ; for in their sport they 
sometimes gallop their poor subjects most unmercifully. 

The shepherd -dog comes to the house every day for some 
moat, and as soon as it is given him, he skulks away as ii 
ashamed of himself. On these occasions the house-dogs are 
very tyrannical, and the least of them will attack and pursue the 
stranger. The minute, however, the latter has reached the 
flock, he turns round and begins to bark, and then all the house- 
dogs take very quickly to their heels. In a similar manner a 
whole pack of the hungry wild dogs will scarcely ever (and I 
was told by some never) venture to attack a flock guarded by 
even one of these faithful shepherds. The whole account ap- 
pears to me a curious instance of the pliability of the affections 
in the dog ; and yet, whether wild or however educated, he has a 
feeling of respect or fear for those that are fulfilling their in- 
stinct of association. For we can understand on no principle 
the wild dogs being driven away by the single one with its flock, 
except that they consider, from some confused notion, that the 
one thus associated gains power, as if in company with its own 
kind. F. Cuvier has observed, that all animals that readily 
enter into domestication, consider man as a member of their 



1833.] BEEAKING-IN WILD HORSES. 151 

own society, and thus fulfil their instinct of association. In the 
above case the shepherd-dog ranks the sheep as its fellow- 
brethren, and thus gains confidence ; and the wild dogs, though 
knowing that the individual sheep are not dogs, but are good to 
eat, yet partly consent to this view when seeing them in a flock 
with a shepherd-dog at their head. 

One evening a " domidor" (a subduer of horses) came for the 
purpose of brea-king-in some colts. I will describe the prepara- 
tory steps, for I believe they have not been mentioned by other 
travellers. A troop of wild young horses is driven into the 
corral, or large enclosure of stakes, and the door is shut. We 
will suppose that one man alone has to catch and mount a horse, 
which as yet had never felt bridle or saddle. I conceive, except 
by a Gaucho, such a feat would be utterly impracticable. The 
Gaucho picks out a full-grown colt; and as the beast rushes 
round the circus, he throws his lazo so as to catch both the front 
legs. Instantly the horse rolls over with a heavy shock, and 
whilst struggling on the ground, the Gaucho, holding the lazo 
tight, makes a circle, so as to catch one of the hind legs, just 
beneath the fetlock, and draws it close to the two front legs : 
he then hitches the lazo, so that the three are bound together. 
Then sitting on the horse's neck, he fixes a strong bridle, with- 
out a bit, to the lower jaw : this he does by passing a narrow 
thong through the eye-holes at the end of the reins, and several 
times round both jaw and tongue.. The two front legs are now 
tied closely together with a strong leathern thong, fastened by 
a slip-knot. The lazo, which bound the three together, being 
then loosed, the horse rises with difficulty. The Gaucho now 
holding fast the bridle fixed to the lower jaw, leads the horse 
outside the corral. If a second man is present (otherwise the 
trouble is much greater) he holds the animal's head, whilst the 
first puts on the horsecloths and saddle, and girths the whole to- 
gether. During this operation, the horse, from dread and asto- 
nishment at thus being bound round the waist, throws himself 
over and over again on the ground, and, till beaten, is unwilling 
to rise. At last, when the saddling is finished, the poor animal 
can hardly breathe from fear, and is white with foam and sweat. 
The man now prepares to mount by pressing heavily on the 
stirrup, so that the horse may not lose its balance ; and at the 



152 BAND A ORIENTAL. [CHAP. TIII. 

moment that he throws his leg over the animal's back, he pulls 
the slip-knot binding the front legs, and the beast is free. Some 
" domidors" pull the knot while the animal is lying on the 
ground, and, standing over the saddle, allow him to rise beneath 
them. The horse, wild with dread, gives a few most violent 
bounds, and then starts off at full gallop : when quite exhausted, 
the man, by patience, brings him back to the corral, where, 
reeking hot and scarcely alive, the poor beast is let free. Those 
animals which will not gallop away, but obstinately throw them- 
selves on the ground, are by far the most troublesome. This 
process is tremendously severe, but in two or three trials the 
horse is tamed. It is not, however, for some weeks that the 
animal is ridden with the iron bit and solid ring, for it must 
learn to associate the will of its rider with the feel of the rein, 
before the most powerful bridle can be of any service. 

Animals are so abundant in these countries, that humanity and 
self-interest are not closely united ; therefore I fear it is that the 
former is here scarcely known. One day, riding in the Pampas 
with a very respectable " Estanciero," my horse, being tired, 
lagged behind. The man often shouted to me to spur him. 
When I remonstrated that it was a pity, for the horse was quite 
exhausted, he cried out, " Why not ? never mind spur him 
it is my horse." I had then some difficulty in making him 
comprehend that it was for the horse's sake, and not on his ac- 
count, that I did not choose to use my spurs. He" exclaimed, 
with a look of great surprise, " Ah, Don Carlos, que cosa !" It 
was clear that such an idea had never before entered his head. 

The Gauchos are well known to be perfect riders. The idea 
of being thrown, let the horse do what it likes, never enters their 
head. Their criterion of a good rider is, a man who can manage 
an untamed colt, or who, if his horse falls, alights on his own 
feet, or can perform other such exploits. I have heard of a man 
betting that he would throw his horse down twenty times, and 
that nineteen times he would not fall himself. I recollect seeing 
a Gaucho riding a very stubborn horse, which three times suc- 
cessively reared so high as to fall backwards with great violence. 
The man judged with uncommon coolness the proper moment 
for slipping off, not an instant before or after the right time ; 
and as soon as the horse got up, the man jumped on his back, and 



HORSEMANSHIP IN CHILE. 153 

at last they started at a gallop. The Gaucho never appears to 
exert any muscular force. I was one day watching a good rider, 
as we were galloping along at a rapid pace, and thought to my- 
self, " surely if the horse starts, you appear so careless on your 
seat, you must fall." At this moment, a male ostrich sprang 
from its nest right beneath the horse's nose : the young colt 
bounded on one side like a stag ; but as for the man, all that 
could be said was, that he started and took fright with his 
horse. 

In Chile and Peru more pains are taken with the mouth of the 
horse than in La Plata, and this is evidently a consequence of 
the more intricate nature of the country. In Chile a horse is 
not considered perfectly broken, till he can be brought up stand- 
ing, in the midst of his full speed, on any particular spot, for 
instance, on a cloak thrown on the ground : or, again, he will 
charge a wall, and rearing, scrape the surface with his hoofs. 
I have seen an animal bounding with spirit, yet merely reined 
by a fore-finger and thumb, taken at full gallop across a court- 
yard, and then made to wheel round the post of a veranda with 
great speed, but at so equal a distance, that the rider, with out- 
stretched arm, all the while kept one finger rubbing the post. 
Then making a demi-volte in the air, with the other arm out- 
stretched in a like manner, he wheeled round, with astonishing 
force, in an opposite direction. 

Such a horse is well broken ; and although this at first may 
appear useless, it is far otherwise. It is only carrying that 
which is daily necessary into perfection. When a bullock is 
checked and caught by the lazo, it will sometimes gallop round 
and round in a circle, and the horse being alarmed at the great 
strain, if not well broken, will not readily turn like the pivot 
of a wheel. In consequence many men have been killed ; for 
if the lazo once takes a twist round a man's body, it will in- 
stantly, from the power of the two opposed animals, almost cut 
him in twain. On the same principle the races are managed ; 
the course is only two or three hundred yards long, the wish 
being to have horses that can make a rapid dash. The race- 
horses are trained not only to stand with their hoofs touching a 
line, but to draw all four feet together, so as at the first spring 
to bring into play the full action of the hind-quarters. In Chile 



154 BANDA ORIENTAL. [CHAP. vin. 

I was told an anecdote, which I believe was true ; and it offers 
a good illustration of the use of a well-broken animal. A re- 
spectable man riding one day met two others, one of whom was 
mounted on a horse, which he knew to have been stolen from 
himself. He challenged them ; they answered him by drawing 
their sabres and giving chace. The man, on his good and fleet 
beast, kept just ahead : as he passed a thick bush he wheeled 
round it, and brought up his horse to a dead check. The pur- 
suers were obliged to shoot on one side and ahead. Then in- 
stantly dashing on, right behind them, he buried his knife in the 
back of one, wounded the other, recovered his horse from the 
dying robber, and rode home. For these feats of horseman hip 
two things are necessary : a most severe bit, like the Mameluke, 
the power of which, though seldom used, the horse knows full 
well ; and large blunt spurs, that can be applied either as a mere 
touch, or as an instrument of extreme pain. I conceive that 
with English spurs, the slightest touch of which pricks the skin, 
it would be impossible to break in a horse after the South Ame- 
rican fashion. 

At an estancia near Las Vacas large numbers of mares are 
weekly slaughtered for the sake of their hides, although worth 
only five paper dollars, or about half-a-crown apiece. It seems 
at first strange that it can answer to kill mares for such a trifle ; 
but as it is thought ridiculous in this country ever to break in or 
ride a mare, they are of no value except for breeding. The only 
thing for which I ever saw mares used, was to tread out wheat 
from the ear ; for which purpose they were driven round a cir- 
cular enclosure, where the wheat-sheaves were strewed. The 
man employed for slaughtering the mares happened to be cele- 
brated for his dexterity with the lazo. Standing at the distance of 
twelve yards from the mouth of the corral, he has laid a wager 
that he would catch by the legs every animal, without missing 
one, as it rushed past him. There was another man who said he 
would enter the corral on foot, catch a mare, fasten her front legs 
together, drive her out, throw her down, kill, skin, and stake the 
hide for drying (which latter is a tedious job) ; and he engaged 
that he would perform this whole operation on twenty-two ani- 
mals in one day. Or he would kill and take the skin off fifty in 
the same time. This would have been a prodigious task, for it is 



1833.] REMAINS OF THE TOXODON. 155 

considered a good day's work to skin and stake the hides of fifteen 
or sixteen animals. 

November 26th. I set out on my return in a direct line for 
Monte Video. Plaving heard of some giant's bones at a neigh- 
bouring farm-house on the Sarandis, a small stream entering the 
Rio Negro, I rode there accompanied by my host, and purchased 
for the value of eighteen pence the head of the Toxodon.* When 
found it was quite perfect ; but the boys knocked out some of the 
teeth with stones, and then set up the head as a mark to throw at. 
By a most fortunate chance I found a perfect tooth, which exactly 
fitted one of the sockets in this skull, embedded by itself on the 
banks of the Rio Tercero, at the distance of about 180 miles 
from this place. I found remains of this extraordinary animal 
at two other places, so that it must formerly have been commqn. 
I found here, also, some large portions of the armour of a gigantic 
armadillo-like animal, and part of the great head of a Mylodon. 
The bones of this head are so fresh, that they contain, accord- 
ing to the analysis by Mr. T. Reeks, seven per cent, of animal 
matter ; and when placed in a spirit-lamp, they burn with a small 
fiame. The number of the remains embedded in the grand 
estuary deposit which forms the Pampas and covers the granitic 
rocks of Banda Oriental, must be extraordinarily great. I believe 
a straight line drawn in any direction through the Pampas would 
cut through some skeleton or bones. Besides those which I 
found during my short excursions, I heard of many others, and 
the origin of such names as " the stream of the animal," " the 
hill of the giant," is obvious. At other times I heard of the 
marvellous property of certain rivers, which had the power of 
changing small bones into large ; or, as some maintained, the 
bones themselves grew. As far as I am aware, not one of these 
animals perished, as was formerly supposed, in the marshes or 
muddy river-beds of the present land, but their bones have been 
exposed by the streams intersecting the subaqueous deposit in 
which they were originally embedded. We may conclude that 
the whole area of the Pampas is one wide sepulchre of these 
extinct gigantic quadrupeds. 

* I must express my obligation to Mr. Keane, at whose house I was staying 
on the Berquelo, and to Mr. Lumb at Buenos Ayres, for without their 
assistance these valuable remains would never have reached England. 



156 BAND A ORIENTAL. [CHAP. Tin. 

By the middle of the day, on the 28th, we arrived at Monte 
Video, having been two days and a half on the road. The 
country for the whole way was of a very uniform character, 
some parts being rather more rocky and hilly than near 
the Plata. Not far from Monte Video we passed through 
the village of Las Pietras. so named from some large rounded 
masses of syenite. Its appearance was rather pretty. In this 
country a few fig-trees round a group of houses, and a site ele- 
vated a hundred feet above the general level, ought always to be 
called picturesque. 

During the last six months I have had an opportunity of seeing 
a little of the character of the inhabitants of these provinces. 
Tbe Gauchos, or countrymen, are very superior to those who 
reside in the towns. The Gaucho is invariably most obliging, 
polite, and hospitable : I did not meet with even one instance of 
rudeness or inhospitality. He is modest, both respecting himself 
and country, but at the same time a spirited, bold fellow. On 
the other hand, many robberies are committed, and there is much 
bloodshed : the habit of constantly wearing the knife is the chief 
cause of the latter. It is lamentable to hear how many lives are 
lost in trifling quarrels. In fighting, each party tries to mark 
the face of his adversary by slashing his nose or eyes ; as is often 
attested by deep and horrid-looking scars. Robberies are a 
natural consequence of universal gambling, much drinking, and 
extreme indolence. At Mercedes I asked two men why they 
did not work. One gravely said the days were too long ; the 
other that he was too poor. The number of horses and the pro- 
fusion of food are the destruction of all industry. Moreover, 
there are so many feast-days ; and again, nothing can succeed 
without it be begun when the moon is on the increase ; so that 
half the month is lost from these two causes. 

Police and justice are quite inefficient. If a man who is poor 
commits murder and is taken, he will be imprisoned, and perhaps 
even shot ; but if he is rich and has friends, he may rely on it no 
very severe consequence will ensue. It is curious that the most 
respectable inhabitants of the country invariably assist a murderer 
to escape : they seem to think that the individual sins against the 
government, and not against the people. A traveller lias no pro- 



1833.] STATE OF SOCIETY. 157 

tection besides his fire-arms ; and the constant habit of carrying 
thorn is the main check to more frequent robberies. 

The character of the higher and more educated classes who 
reside in the towns, partakes, but perhaps in a lesser degree, of the 
good parts of the Gaucho, but is, I fear, stained by many vices of 
which he is free. Sensuality, mockery of all religion, and the 
grossest corruption, are far from uncommon. Nearly every 
public officer can be bribed. The head man in the post-office 
sold forged government franks. The governor and prime minister 
openly combined to plunder the state. Justice, where gold came 
into play, was hardly expected by any one. I knew an English- 
man, who went to the Chief Justice (he told me, that not then 
understanding the ways of the place, he trembled as he entered 
the room), and said, " Sir, I have come to offer you two hundred 
(paper) dollars (value about five pounds sterling) if you will arrest 
before a certain time a man who has cheated me. I know it is 
against the law, but my lawyer (naming him) recommended me to 
take this step." The Chief Justice smiled acquiescence, thanked 
him, and the man before night was safe in prison. With this entire 
want of principle in many of the leading men, with the country 
full of ill-paid turbulent officers, the people yet hope that a de- 
mocratic form of government can succeed ! 

On first entering society in these countries, two or three 
features strike one as particularly remarkable. The polite and 
dignified manners pervading every rank of life, the excellent 
taste displayed by the women in their dresses, and the equality 
amongst all ranks. At the Rio Colorado some men who kept 
the humblest shops used to dine with General Rosas. A son of a 
majpr at Bahia Blanca gained his livelihood by making paper 
cigars, and he wished to accompany me, as guide or servant, to 
Buenos Ayres, but his father objected on the score of the danger 
alone. Many officers in the army can neither read nor write, yet 
all meet in society as equals. In Entre Rios, the Sala consisted 
of only six representatives. One of them kept a common shop, 
and evidently was not degraded by the office. All this is what 
would be expected in a new country ; nevertheless the absence of 
gentlemen by profession appears to an Englishman something 
strange. 

When speaking of these countries, the manner in which they 



158 EIO PLATA. [CHAP. vm. 

have been brought up by their unnatural parent, Spain, should 
always be borne in mind. On the whole, perhaps, more credit 
is due for what has been done, than blame for that which may be 
deficient. It is impossible to doubt but that the extreme liberalism 
of these countries must ultimately lead to good results. The very 
general toleration of foreign religions, the regard paid to the 
means of education, the freedom of the press, the facilities 
offered to all foreigners, and especially, as I am bound to add, to 
every one professing the humblest pretensions to science, should 
be recollected with gratitude by those who have visited Spanish 
South America. 

December 6th. The Beagle sailed from the Rio Plata, 
never again to enter its muddy stream. Our course was directed 
to Port Desire, on the coast of Patagonia. Before proceeding 
any further, I will here put together a few observations made at 
sea. 

Several times when the ship has been some miles off the mouth 
of the Plata, and at other times when off the shores of Northern 
Patagonia, we have been surrounded by insects. One evening, 
when we were about ten miles from the Bay of San Bias, vast 
numbers of butterflies, in bands or flocks of countless myriads, 
extended as far as the eye could range. Even by the aid of a 
telescope it was not possible to see a space free from butterflies. 
The seamen cried out " it was snowing butterflies," and such in 
fact was the appearance. More species than one were present, 
but the main part belonged to a kind very similar to, but not 
identical with, the common English Colias edusa. Some moths 
and hymenoptera accompanied the butterflies ; and a fine beetle 
(Calosoma) flew on board. Other instances are known of this 
beetle having been caught far out at sea ; and this is the more 
remarkable, as the greater number of the Carabidae seldom 01 
never take wing. The day had been fine and calm, and the one 
previous to it equally so, with light and variable airs. Hence 
we cannot suppose that the insects were blown off the land, but 
we must conclude that they voluntarily took flight. The great 
bands of the Colias seem at first to afford an instance like those 
on record of the migrations of another butterfly, Vanessa cardui ;* 

* Lyell's Principles of Geology, vol. iii. p. 63. 



1833.] FLOCKS OF BUTTERFLIES. 159 

but the presence of other insects makes the case distinct, and even 
less intelligible. Before sunset a strong breeze sprung up from 
the north, and this must have caused tens of thousands of the 
butterflies and other insects to have perished. 

On another occasion, when seventeen miles off Cape Corrientes, 
I had a net overboard to catch pelagic animals. Upon drawing 
it up, to my surprise I found a considerable number of beetles in 
it, and although in the open sea, they did not appear much in- 
jured by the salt water. I lost some of the specimens, but those 
which I preserved belonged to the genera Colymbetes, Hydropo- 
rus, Hydrobius (two species), Notaphus, Cynucus, Adimonia, and 
Scarabaeus. At first I thought that these insects had been blown 
from the shore ; but upon reflecting that out of the eight species 
four were aquatic, and two others partly so in their habits, it ap- 
peared to me most probable that they were floated into the sea 
by a small stream which drains a lake near Cape Corrientes. On 
any supposition it is an interesting circumstance to find live insects 
swimming in the open ocean seventeen miles from the nearest 
point of land. There are several accounts of insects having been 
blown off the Patagonian shore. Captain Cook observed it, as 
did more lately Captain King in the Adventure. The cause 
probably is due to the want of shelter, both of trees and hills, so 
that an insect on the wing, with an off-shore breeze, would be 
very apt to be blown out to sea. The most remarkable instance 
I have known of an insect being caught far from the land, was 
that of a large grasshopper (Acrydium), which flew on board, 
when the Beagle was to windward of the Cape de Verd Islands, 
and when the nearest point of land, not directly opposed to the 
trade-wind, was Cape Blanco on the coast of Africa, 370 miles 
distant.* 

On several occasions, when the Beagle has been within the 
mouth of the Plata, the rigging has been coated with the web of 
the Gossamer Spider. One day (November 1st, 1832) I paid 
particular attention to this subject. 1"he weather had been fine 
and clear, and in the morning the air was full of patches of the 
flocculent web, as on an autumnal day in England. The ship

passage from harbour to harbour, wandering from the vessel, are soon lost, 
and all disappear.

was sixty miles distant from the land, in the direction of a steady 
though light breeze. Vast numbers of a small spider, about one- 
tenth of aa inch in length, and of a dusky red colour, were attached 
to the webs. There must have been, I should suppose, some 
thousands on the ship. The little spider, when first coming in 
contact with the rigging, was always seated on a single thread, 
and not on the flocculent mass. This latter seems merely to be 
produced by the entanglement of the single threads. The spiders 
were all of one species, but of both sexes, together with young 
ones. These latter were distinguished by their smaller size and 
more dusky colour. I will not give the description of this spider, 
but merely state that it does not appear to me to be included in 
any of Latreille's genera. The little aeronaut as soon as it arrived 
on board was very active, running about, sometimes letting itself 
fall, and then reascending the same thread ; sometimes employing 
itself in making a small and very irregular mesh in the corners 
between the ropes. It could run with facility on the surface of 
water. When disturbed it lifted up its front legs, in the attitude 
of attention. On its first arrival it appeared very thirsty, and 
with exserted maxillae drank eagerly of drops of water; this same 
circumstance has been observed by Strack : may it not be in con- 
sequence of the little insect having passed through a dry and rare- 
fied atmosphere ? Its stock of web seemed inexhaustible. While 
watching some that were suspended by a single thread, I several 
times observed that the slightest breath of air bore them away 
out of sight, in a horizontal line. On another occasion (25th) 
under similar circumstances, I repeatedly observed the same kind 
of small spider, either when placed or having crawled on some 
little eminence, elevate its abdomen, send forth a thread, and then 
sail away horizontally, but with a rapidity which was quite un- 
accountable. I thought I could perceive that the spider, before 
performing the above preparatory steps, connected its legs toge- 
ther with the most delicate threads, but I am not sure whether 
this observation was correct. 

One day, at St. Ft?, I had a better opportunity of observing 
borne similar facts. A spider which was about three-tenths of 
an inch in length, and which in its general appearance resembled 
a Citigrade (therefore quite different from the gossamer), while 
standing on the summit of a post, darted forth four or five threads 



1833.] AERONAUT SPIDERS. 161 

from its spinners. These, glittering in the sunshine, might be 
compared to diverging rays of light ; they were not, however, 
straight, but in undulations like films of silk blown by the wind. 
They were more than a yard in length, and diverged in an ascend- 
ing direction from the orifices. The spider then suddenly let go 
its hold of the post, and was quickly borne out of sight. The 
day was hot and apparently quite calm ; yet under such circum- 
stances, the atmosphere can never be so tranquil as not to affect 
a vane so delicate as the thread of a spider's web. If during a 
warm day we look either at the shadow of any object cast on a 
bank, or over a level plain at a distant landmark, the effect of an 
ascending current of heated air is almost always evident : such 
upward currents, it has been remarked, are also shown by the 
ascent of soap-bubbles, which will not rise in an in-doors room. 
Hence I think there is not much difficulty in understanding the 
ascent of the fine lines projected from a spider's spinners, and 
afterwards of the spider itself; the divergence of the lines has 
been attempted to be explained, I believe by Mr. Murray, by 
their similar electrical condition. The circumstance of spiders 
of the same species, but of different sexes and ages, being found 
on several occasions at the distance of many leagues from the 
land, attached in vast numbers to the lines, renders it probable 
that the habit of sailing through the air is as characteristic of 
this tribe, as that of diving is of the Argyroneta. We may then 
reject Latreille's supposition, that the gossamer owes its origin 
indifferently to the young of several genera of spiders : although, 
as we have seen, the young of other spiders do possess the power 
of performing aerial voyages.* 

During our different passages south of the Plata, I often towed 
astern a net made of bunting, and thus caught many curious ani- 
mals. Of Crustacea there were many strange and undescribed 
genera. One, which in some respects is allied to the Notopods 
(or those crabs which have their posterior legs placed almost on 
their backs, for the purpose of adhering to the under side of 
rocks), is very remarkable from the structure of its hind pair of 
legs. The penultimate joint, instead of terminating in a simple 
claw, ends in three bristle-like appendages of dissimilar lengths 

* Mr. Blackball, in his Researches in Zoology, has many excellent ob- 
servations on the habits of spiders. 



1C2 ATLANTIC OCEAN. [CHAP. TIII. 

the longest equalling that of the entire leg. These claws are 
very thin, and are serrated with the finest teeth, directed back- 
wards : their curved extremities are flattened, and on this part 
five most minute cups are placed which seem to act in the same 
manner as the suckers on the arms of the cuttle-fish. As the 
animal lives in the open sea, and probably wants a place of rest, 
I suppose this beautiful and most anomalous structure is adapted 
to take hold of floating marine animals. 

In deep water, far from the land, the number of living crea- 
tures is extremely small : south of the latitude 35, I never suc- 
ceeded in catching anything besides some beroe, and a few species 
of minute entomostracous Crustacea. In shoaler water, at the 
distance of a few miles from the coast, very many kinds of crus- 
tacea and some other animals are numerous, but only during the 
night. Between latitudes 56 and 57 south of Cape Horn, the 
net was put astern several times ; it never, however, brought up 
anything besides a few of two extremely minute species of Ento- 
mostraca. Yet whales and seals, petrels and albatross, are ex- 
ceedingly abundant throughout this part of the ocean. It has 
always been a mystery to me on what the albatross, which lives 
far from the shore, can subsist ; I presume that, like the condor, 
it is able to fast long ; and that one good feast on the carcass 
of a putrid whale lasts for a long time. The central and inter- 
tropical parts of the Atlantic swarm with Pteropoda, Crustacea, 
and Radiata, and with their devourers the flying-fish, and again 
with their devourers the bonitos and albicores ; I presume that 
the numerous lower pelagic animals feed on the Infusoria, which 
are now known, from the researches of Ehrenberg, to abound in 
the open ocean : but on what, in the clear blue water, do these 
Infusoria subsist ? 

While sailing a little south of the Plata on one very dark 
night, the sea presented a wonderful and most beautiful spec- 
tacle. There was a fresh breeze, and every part of the sur- 
face, which during the day is seen as foam, now glowed with 
a pale light. The vessel drove before her bows two billows 
of liquid phosphorus, and in her wake she was followed by a 
milky train. As far as the eye reached, the crest of every 
wave was bright, and the sky above the horizon, from the re- 
flected glare of these livid flames, was not so utterly obscure 
as over the vault of the heavens 



PHOSPHORESCENCE OF THE SEA. 163 

As we proceed further southward the sea is seldom phospho- 
rescent ; and off Cape Horn I do not recollect more than once 
having seen it so, and then it was far from being brilliant. This 
circumstance probably has a close connexion with the scarcity of 
organic beings in that part of the ocean. After the elaborate 
paper * by Ehrenberg, on the phosphorescence of the sea, it is 
almost superfluous on my part to make any observations on the 
subject. I may however add, that the same torn and irregular 
particles of gelatinous matter, described by Ehrenberg, seem in 
the southern as well as in the northern hemisphere, to be the 
common cause of this phenomenon. The particles were so 
minute as easily to pass through fine gauze ; yet many were dis- 
tinctly visible by the naked eye. The water when placed in a 
tumbler and agitated, gave out sparks, but a small portion in a 
watch -glass scarcely ever was luminous. Ehrenberg states that 
these particles all retain a certain degree of irritability. My 
observations, some of which were made directly after taking up 
the water, gave a different result. I may also mention, that 
having used the net during one night, I allowed it to become 
partially dry, and having occasion twelve hours afterwards to 
employ it again, I found the whole surface sparkled as brightly 
as when first taken out of the water. It does not appear pro- 
bable in this case, that the particles could have remained so long 
alive. On one occasion having kept a jelly-fish of the genus 
Dianeea till it was dead, the water in which it was placed became 
luminous. When the waves scintillate with bright green sparks, 
I believe it is generally owing to minute Crustacea. But there 
can be no doubt that very many other pelagic animals, when 
alive, are phosphorescent. 

On two occasions I have observed the sea luminous at con- 
siderable depths beneath the surface. Near the mouth of the 
Plata some circular and oval patches, from two to four yards in 
diameter, and with defined outlines, shone with a steady but pale 
light ; while the surrounding water only gave out a few sparks. 
The appearance resembled the reflection of the moon, or some 
luminous body ; for the edges were sinuous from the undulations 
of the surface. The ship, which drew thirteen feet water, passed

Botany. 



164 PORT DESIRE. [CHAP. TIII. 

over, without disturbing these patches. Therefore we must sup- 
pose that some animals were congregated together at a greater 
depth than the bottom of the vessel. 

Near Fernando Noronha the sea gave out light in flashes. 
The appearance was very similar to that which might be expected 
from a large fish moving rapidly through a luminous fluid. 
To this cause the sailors attributed it ; at the time, however, 1 
entertained some doubts, on account of the frequency and rapid- 
ity of the flashes. I have already remarked that the phenome- 
non is very much more common in warm than in cold countries ; 
and I have sometimes imagined that a disturbed electrical con- 
dition of the atmosphere was most favourable to its production. 
Certainly I think the sea is most luminous after a few days of 
more calm weather than ordinary, during which time it has 
swarmed with various animals. Observing that the water 
charged with gelatinous particles is in an impure state, and that 
the luminous appearance in all common cases is produced by the 
agitation of the fluid in contact with the atmosphere, I am in- 
clined to consider that the phosphorescence is the result of the 
decomposition of the organic particles, by which process (one is 
tempted almost to call it a kind of respiration) the ocean becomes 
purified. 

December 23rd. "We arrived at Port Desire, situated in lat. 
47, on the coast of Patagonia. The creek runs for about twenty 
miles inland, with an irregular width. The Beagle anchored a 
few miles within the entrance, in front of the ruins of an old 
Spanish settlement. 

The same evening I went on shore. The first landing in any 
new country is very interesting, and especially when, as in this 
case, the whole aspect bears the stamp of a marked and individual 
character. At the height of between two and three hundred 
feet above some masses of porphyry a wide plain extends, which 
is truly characteristic of Patagonia. The surface is quite level, 
and is composed of well-rounded shingle mixed with a whitish 
earth. Here and there scattered tufts of brown wiry grass are 
supported, and, still more rarely, some low thorny bushes. The 
weather is dry and pleasant, and the fine blue sky is but seldom 
obscured. When standing in the middle of one of these desert 



1833.] SPANISH SETTLEMENT. 165 

plains and looking towards the interior, the view is generally 
bounded by the escarpment of another plain, rather higher, but 
equally level and desolate ; and in every other direction the hori- 
zon is indistinct from the trembling mirage which seems to rise 
from the heated surface. 

In such a country the fate of the Spanish settlement was soon 
decided ; the dryness of the climate during the greater part of 
the year, and the occasional hostile attacks of the wandering 
Indians, compelled the colonists to desert their half-finished 
buildings. The style, however, in which they were commenced 
shows the strong and liberal hand of Spain in the old time. 
The result of all the attempts to colonize this side of America 
south of 41, have been miserable. Port Famine expresses by its 
name the lingering and extreme sufferings of several hundred 
wretched people, of whom one alone survived to relate their mis- 
fortunes. At St. Joseph's Bay, on the coast of Patagonia, a 
small settlement was made ; but during one Sunday the Indians 
made an attack and massacred the whole party, excepting two 
men, who remained captives during many years. At the Rio 
Negro I conversed with one of these men, now in extreme old age. 

The zoology of Patagonia is as limited as its Flora.* On the 
arid plains a few black beetles (Heteromera) might be seen 
slowly crawling about, and occasionally a lizard darted from side 
to side. Of birds we have three carrion hawks, and in the val- 
leys a few finches and insect-feeders. An ibis (Theristicus me- 
lanops a species said to be found in central Africa) is not 
uncommon on the most desert parts : in their stomachs I found 
grasshoppers, cicadae, small lizards, and even scorpions ^ At 
one time of the year these birds go in flocks, at another in pairs ; 
their cry is very loud and singular, like the neighing of the 
guanaco, 

* I found here a species of cactus, described by Professor Henslow, under 
the name of Opuntia Darwinii (Magazine of Zoology and Botany, vol. i. 
p. 406), -which was remarkable by the irritability of the stamens, when I 
inserted either a piece of stick or the end of my finger in the flower. The 
segments of the perianth also closed on the pistil, but more slowly than the 
stamens. Plants of this family, generally considered as tropical, occur in North 
America (Lewis and Clarke's Travels, p. 221), in the same high latitude 
as here, namely, in both cases, in 47. 

t These insects were not uncommon beneath stones. I found one cannibal 
scorpion quietly devouring another. 



166 PORT DESIRE. [CHAP. vm. 

The guanaco, or wild llama, is the characteristic quadruped 
of the plains of Patagonia ; it is the South American represent- 
ative of the camel of the Eas It is an elegant animal in a 
state of nature, with a long slender neck and fine legs. It is 
very common over the whole of the temperate parts of the con- 
tinent, as far south as the islands near Cape Horn. It generally 
lives in small herds of from half a dozen to thirty in each ; but 
on the banks of the St. Cruz we saw one herd which must have 
contained at least five hundred. 

They are generally wild and extremely wary. Mr. Stokes 
told me, that he one day saw through a glass a herd of these 
animals which evidently had been frightened, and were running 
away at full speed, although their distance was so great that he 
could not distinguish them with his naked eye. The sportsman 
frequently receives the first notice of their presence, by hearing 
from a long distance their peculiar shrill neighing note of alarm. 
If he then looks attentively, he will probably see the herd stand- 
ing in a line on the side of some distant hill. On approaching 
nearer, a few more squeals are given, and off they set at an ap- 
parently slow, but really quick canter, along some narrow beaten 
track to a neighbouring hill. If, however, by chance he abruptly 
meets a single animal, or several together, they will generally 
stand motionless and intently gaze at him ; then perhaps move 
on a few yards, turn round, and look again. What is the cause 
of this difference in their shyness ? Do they mistake a man in 
the distance for their chief enemy the puma ? Or does curiosity 
overcome their timidity ? That they are curious is certain ; for 
if a person lies on the ground, and plays strange antics, such as 
throwing up his feet in the air, they will almost always approach 
by degrees to reconnoitre him. It was an artifice that was 
repeatedly practised by our sportsmen with success, and it had 
moreover the advantage of allowing several shots to be fired, 
which were all taken as parts of the performance. On the moun~ 
tains of Tierra del Fuego, I have more than once seen a guanaco, 
Dn being approached, not only neigh and squeal, but prance and 
leap about in the most ridiculous manner, apparently in defiance 
as a challenge. These animals are very easily domesticated, and 
I have seen some thus kept in northern Patagonia near a house, 
though not under any restraint They are in this state very

bold, and readily attack a man by striking him from behind with 
both knees. It is asserted that the motive for these attacks is 
jealousy on account of their females. The wild guanacos, how- 
ever, have no idea of defence ; even a single dog will secure one 
of these large animals, till the huntsman can come up. In many 
of their habits they are like sheep in a flock. Thus when they 
see men approaching in several directions on horseback, they 
soon become bewildered, and know not which way to run. This 
greatly facilitates the Indian method of hunting, for they are 
thus easily driven to a central point, and are encompassed. 

The guanacos readily take to the water : several times ai 
Port Valdes they were seen swimming from island to island. 
Byron, in his voyage, says he saw them drinking salt water. 
Some of our officers likewise saw a herd apparently drinking the 
briny fluid from a salina near Cape Blanco. I imagine in several 
parts of the country, if they do not drink salt water, they drink 
none at all. In the middle of the day they frequently roll in the 
dust, in saucer-shaped hollows. The males fight together ; two 
one day passed quite close to me, squealing and trying to bite 
each other ; and several were shot with their hides deeply scored. 
Herds sometimes appear to set out on exploring parties: at 
Bahia Blanca, where, within thirty miles of the coast, these 
animals are extremely unfrequent, I one day saw the tracks of 
thirty or forty, which had come in a direct line to a muddy salt- 
water creek. They then must have perceived that they were 
approaching the sea, for they had wheeled with the regularity of 
cavalry, and had returned back in as straight a line as they had 
advanced. The guanacos have one singular habit, which is to 
me quite inexplicable ; namely, that on successive days they 
drop their dung in the same defined heap. I saw one of these 
heaps which was eight feet in diameter, and was composed of a 
large quantity. This habit, according to M. A. d'Orbigny, is 
common to all the species of the genus ; it is very useful to the 
Peruvian Indians, who use the dung for fuel, and are thus saved 
the trouble of collecting it. 

The guanacos appear to have favourite spots for lying down 
to die. On the banks of the St. Cruz, in certain circumscribed 
spaces, which were generally bushy and all near the river, the 
ground was actually white with bones. On one such spot I

counter! between ten and twenty heads. I particularly examined 
the bones ; they did not appear, as some scattered ones which I 
had seen, gnawed or broken, as if dragged together by beasts of 
prey. The animals in most cases must have crawled, before 
dying, beneath and amongst the bushes. Mr. Bynoe informs me 
that during a former voyage he observed the same circumstance 
on the banks of the Rio Gallegos. I do not at all understand 
the reason of this, but I may observe, that the wounded guana- 
cos at the St. Cruz invariably walked towards the river. At 
St. Jago in the Cape de Verd islands, I remember having seen 
in a ravine a retired corner covered with bones of the goat ; we 
at the time exclaimed that it was the burial-ground of all the 
goats in the island. I mention these trifling circumstances, be- 
cause in certain cases they might explain the occurrence of a 
number of uninjured bones in a cave, or buried under alluvial 
accumulations; and likewise the cause why certain animals are 
more commonly embedded than others in sedimentary deposits. 

One day the yawl was sent under the command of Mr. Chaffers 
with three days' provisions to survey the upper part of the har- 
bour. In the morning we searched for some watering-places 
mentioned in an old Spanish chart. We found one creek, at the 
head of which there was a trickling rill (the first we had seen) 
of brackish water. Here the tide compelled us to wait several 
hours ; and in the interval I walked some miles into the interior. 
The plain as usual consisted of gravel, mingled with soil resem- 
bling chalk in appearance, but very different from it in nature. 
From the softness of these materials it was worn into many 
gulleys. There was not a tree, and, excepting the guanaco, which 
stood on the hill-top a watchful sentinel over its herd, scarcely 
an animal or a bird. All was stillness and desolation. Yet in 
passing over these scenes, without one bright object near, an ill- 
defined but strong sense of pleasure is vividly excited. One 
asked how many ages the plain had thus lasted, and how many 
more it was doomed thus to continue. 

None can reply all seems eternal now. 
The wilderness has a mysterious tongue, 
Which teaches awful doubt.* 

* Shelley, Lines on M. Blanc. 



1834.] INDIAN GRATE. 169 

In the evening we sailed a few miles further up, and then 
pitched the tents for the night. By the middle of the next day 
the yawl was aground, and from the shoalness of the water could 
not proceed any higher. The water being found partly fresh, 
Mr. Chaffers took the dingey and went up two or three miles 
further, where she also grounded, but in a fresh-water river 
The water was muddy, and though the stream was most insigni 
ficant in size, it would be difficult to account for its origin, 
except from the melting snow on the Cordillera. At the spot 
where we bivouacked, we were surrounded by bold cliffs and 
steep pinnacles of porphyry. I do not think I ever saw a spot 
which appeared more secluded from the rest of the world, than 
this rocky crevice in the wide plain. 

The second day after our return to the anchorage, a party of 
officers and myself went to ransack an old Indian grave, which I 
had found on the summit of a neighbouring hill. Two immense 
stones, each probably weighing at least a couple of tons, had 
been placed in front of a ledge of rock about six feet high. At 
the bottom of the grave on the hard rock there was a layer 
of earth about a foot deep, which must have been brought up 
from the plain below. Above it a pavement of flat stones was 
placed, on which others were piled, so as to fill up the space 
between the ledge and the two great blocks. To complete the 
grave, the Indians had contrived to detach from the ledge a huge 
fragment, and to throw it over the pile so as to rest on the two 
blocks. We undermined the grave on both sides, but could not 
find any relics, or even bones. The latter probably had decayed 
long since (in which case the grave must have been of extreme 
antiquity), for I found in another place some smaller heaps, 
beneatli which a very few crumbling fragments could yet be 
distinguished as having belonged to a man. Falconer states, 
that where an Indian dies he is buried, but that subsequently his 
bones are carefully taken up and carried, let the distance be ever 
so great, to be deposited near the sea-coast. This custom, I 
think, may be accounted for by recollecting, that before the in- 
troduction of horses, these Indians must have led nearly the 
same life as the Fuegians now do, and therefore generally have 
resided in the neighbourhood of the sea. The common prejudice 
of lying where one's ancestors have lain, would make the now

roaming Indians bring the less perishable part of their dead to 
their ancient burial-ground on the coast. 

January 9th, 1834. Before it was dark the Beagle anchored 
in the fine spacious harbour of Port St. Julian, situated about 
one hundred and ten miles to the south of Port Desire. We 
remained here eight days. The country is nearly similar to that 
of Port Desire, but perhaps rather more sterile. One day a 
party accompanied Captain Fitz Roy on a long walk round the 
head of the harbour. We were eleven hours without tasting 
any water, and some of the party were quite exhausted. From 
the summit of a hill (since well named Thirsty Hill) a fine lake 
was spied, and two of the party proceeded with concerted signals to 
show whether it was fresh water. What was our disappointment 
to find a snow-white expanse of salt, crystallized in great cubes ! 
We attributed our extreme thirst to the dryness of the atmos- 
phere ; but whatever the cause might be, we were exceedingly 
glad late in the evening to get back to the boats. Although 
we could nowhere find, during our whole visit, a single drop of 
fresh water, yet some must exist ; for by an odd chance I found 
on the surface of the salt water, near the head of the bay, a Co- 
lymbetes not quite dead, which must have lived in some not far 
distant pool. Three other insects (a Cincindela, like hybrida, 
a Cymindis, and a Harpalus, which all live on muddy flats occa- 
sionally overflowed by the sea), and one other found dead on the 
plain, complete the list of the beetles. A good-sized fly (Ta- 
banus) was extremely numerous, and tormented us by its painful 
bite. The common horsefly, which is so troublesome in the 
shady lanes of England, belongs to this same genus. We here 
have the puzzle that so frequently occurs in the case of mus- 
quitoes on the blood of what animals do these insects commonly 
feed ? The guanaco is nearly the only warm-blooded quadruped, 
and it is found in quite inconsiderable numbers compared with 
the multitude of flies. 

The geology of Patagonia is interesting. Differently from 
Europe, where the tertiary formations appear to have accu- 
mulated in bays, here along hundreds of miles of coast we have 
one great deposit, including many tertiary shells, all apparently 
cxtiuct The most common shell is a massive gigantic oyster, 



1834.] GEOLOGY OF PATAGONIA. 171 

sometimes even a foot in diameter. These beds are covered by 
others of a peculiar soft white stone, including much gypsum, 
and resembling chalk, but really of a pumiceous nature. It in 
highly remarkable, from being composed, to at least one- 
tenth part of its bulk, of Infusoria : Professor Ehrenberg hap 
already ascertained in it thirty oceanic forms. This bed extends 
for 500 miles along the coast, and probably for a considerably 
greater distance. At Port St. Julian its thickness is more than 
800 feet ! These white beds are everywhere capped by a mass 
of gravel, forming probably one of the largest beds of shingle in 
the world : it certainly extends from near the Rio Colorado to be- 
tween 600 and 700 nautical miles southward ; at Sunta Cruz (a 
river a little south of St. Julian), it reaches to the foot, of the 
Cordillera ; half way up the river, its thickness is more than 200 
feet ; it probably everywhere extends to this great chain, whence 
the well-rounded pebbles of porphyry have been derived : we 
may consider its average breadth as 200 miles, and its average 
thickness as about 50 feet. If this great bed of pebbles, with- 
out including the mud necessarily derived from their attrition, 
was piled into a mound, it would form a great mountain chain ! 
When we consider that all these pebbles, countless as the grains 
of sand in the desert, have been derived from the slow falling of 
masses of rock on the old coast-lines and banks of rivers ; and 
that these fragments have been dashed into smaller pieces, and 
that each of them has since been slowly rolled, rounded, and 
far transported, the mind is stupified in thinking over the long, 
absolutely necessary, lapse of years. Yet all this gravel has 
been transported, and probably rounded, subsequently to the 
deposition of the white beds, and long subsequently to the under- 
lying beds with the tertiary shells. 

Everything in this southern continent has been effected on a 
grand scale: the land, from the Rio Plata to Tierra del Fuego, 
a distance of 1200 miles, has been raised in mass (and in Pata- 
gonia to a height of between 300 and 400 feet), within the period 
of the now existing sea-shells. The old and weathered shells 
left on the surface of the upraised plain still partially retain 
tht'ir colours. The uprising movement has been interrupted by 
at least eight long periods of rest, during which the sea ate deeply 
back into the land, forming at successive levels the long lines of 



172 GEOLOGY OF PATAGONIA. [CHAP. vin. 

cliffs or escarpments, which separate the different plains as they 
rise like steps one behind the other. The elevatory movement, 
and the eating-back power of the sea during the periods of rest, 
have been equable over long lines of coast ; for I was astonished 
to find that the step-like plains stand at nearly corresponding 
heights at far distant points. The lowest plain is 90 feet high ; 
and the highest, which I ascended near the coast, is 950 feet ; 
and of this, only relics are left in the form of flat gravel- 
capped hills. The upper plain of S. Cruz slopes up to a height 
of 3000 feet at the foot of the Cordillera. I have said that 
within the period of existing sea-shells Patagonia has been up- 
raised 300 to 400 feet: I may add, that within the period 
when icebergs transported boulders over the upper plain of 
Santa Cruz, the elevation has been at least 1500 feet. Nor 
has Patagonia been affected only by upward movements : the 
extinct tertiary shells from Port St. Julian and Santa Cruz cannot 
have lived, according to Professor E. Forbes, in a greater depth 
of water than from 40 to 250 feet ; but they are now covered 
with sea-deposited strata from 800 to 1000 feet in thickness : 
hence the bed of the sea, on which these shells once lived, must 
have sunk downwards several hundred feet, to allow of the accu- 
mulation of the superincumbent strata. What a history of geo- 
logical changes does the simply -constructed coast of Patagonia 
reveal ! 

At Port St. Julian *, in some red mud capping the gravel 
on the 90-feet plain, I found half the skeleton of the Macrau- 
chenia Patachonica, a remarkable quadruped, full as large as a 
camel. It belongs to the same division of the Pachydermata with 
the rhinoceros, tapir, and palaeotherium; but in the structure of the 
bones of its long neck it shows a clear relation to the camel, or 
rather to the guanaco and llama. From recent sea-shells being 
found on two of the higher step-formed plains, which must have 
been modelled and upraised before the mud was deposited in 
which the Macrauchenia was intombed, it is certain that this 
curious quadruped lived long after the sea was inhabited by its 

* I have lately heard that Capt. Sulivan, R.N., has found numerous fossil 
bones, embedded in regular strata, on the banks of the K. Gallegos, in lat. 
51 4'. Some of the bones are large ; others are small, and appear to have 
belonged to an armadillo. This is a most interesting and important di& 
covery.

present shells. I was at first much surprised how a large quad- 
ruped could so lately have subsisted, in lat. 49 15', on these 
wretched gravel plains with their stunted vegetation ; but the 
relationship of the Macrauchenia to the guanaco, now an inha- 
bitant of the most sterile parts, partly explains this difficulty. 

The relationship, though distant, between the Macrauchenia 
and the Guanaco, between the Toxodon and the Capybara, 
the closer relationship between the many extinct Edentata and 
the living sloths, ant-eaters, and armadillos, now so eminently 
characteristic of South American zoology, and the still closer 
relationship between the fossil and living species of Ctenomys and 
Plydrochaerus, are most interesting facts. This relationship is 
shown wonderfully as wonderfully as between the fossil and 
extinct Marsupial animals of Australia by the great collection 
lately brought to Europe from the caves of Brazil by MM. Lund 
and Clausen. In this collection there are extinct species of all 
the thirty-two genera, excepting four, of the terrestrial quadru- 
peds now inhabiting the provinces in which the caves occur ; 
and the extinct species are much more numerous than those now 
living : there are fossil ant-eaters, armadillos, tapirs, peccaries y 
guanacos, opossums, and numerous South American gnawers and 
monkeys, and other animals. This wonderful relationship in the 
same continent between the dead and the living, will, I do not 
doubt, hereafter throw more light on the appearance of organic 
beings on our earth, and their disappearance from it, than any 
other class of facts. 

It is impossible to reflect on the changed state of the American 
continent without the deepest astonishment. Formerly it must 
have swarmed with great monsters : now we find mere pigmies, 
compared with the antecedent, allied races. If BufFon had known 
of the gigantic sloth and armadillo-like animals, and of the lost 
Pachydermata, he might have said with a greater semblance of 
truth that the creative force in America had lost its power, 
rather than that it had never possessed great vigour. The 
greater number, if not all, of these extinct quadrupeds lived at 
a late period, and were the contemporaries of most of the exist- 
ing sea-shells. Since they lived, no very great change in the form 
of the land can have taken place. What, then, has exterminated 
so many species and whole genera ? The mind at first is irre- 



174 CAUSES OF EXTINCTION. [CHAP. Tin. 

sistibly hurried into the belief of some great catastrophe ; but 
thus to destroy animals, both large and small, in Southern Pata- 
gonia, in Brazil, on the Cordillera of Peru, in North America 
up to Behring's Straits, we must shake the entire framework of 
the globe, An examination, moreover, of the geology of La 
Plata and Patagonia, leads to the belief that all the features of 
the land result from slow and gradual changes. It appears from 
the character of the fossils in Europe, Asia, Australia, and in 
North and South America, that those conditions which favour 
the life of the larger quadrupeds were lately co-extensive with 
the world : what those conditions were, no one has yet even 
conjectured. It could hardly have been a change of tempera- 
ture, which at about the same time destroyed the inhabitants of 
tropical, temperate, and arctic latitudes on both sides of the 
globe. In North America we positively know from Mr. Lyell, 
that the large quadrupeds lived subsequently to that period, when 
boulders were brought into latitudes at which icebergs now never 
arrive : from conclusive but indirect reasons we may feel sure, 
that in the southern hemisphere the Macrauchenia, also, lived 
long subsequently to the ice-transporting boulder-period. Did 
man, after his first inroad into South America, destroy, as has 
been suggested, the unwieldy Megatherium and the other Eden- 
tata ? "We must at least look to some other cause for the destruc- 
tion of the little tucutuco at Bahia Blanca, and of the many 
fossil mice and other small quadrupeds in Brazil. No one 
will imagine that a drought, even far severer than those which 
cause such losses in the provinces of La Plata, could destroy 
every individual of every species from Southern Patagonia to 
Behring's Straits. What shall we say of the extinction of the 
horse ? Did those plains fail of pasture, which have since been 
overrun by thousands and hundreds of thousands of the descend- 
ants of the stock introduced by the Spaniards ? Have the subse- 
quently introduced species consumed the food of the great ante- 
cedent races ? Can we believe that the Capybara has taken the 
food of the Toxodon, the Guanaco of the Macrauchenia, the ex- 
isting small Edentata of their numerous gigantic prototypes? 
Certainly, no fact in the long histoiy of the world is so startling 
as the wide and repeated exterminations of its inhabitants. 
Nevertheless, if we consider the subject under another point ol 



1834.] CAUSES OF EXTINCTION. 175 

view, it will appear less perplexing. We do not steadily bear in 
mind, how profoundly ignorant we are of the conditions of exist- 
ence of every animal ; nor do we always remember, that some 
check is constantly preventing the too rapid increase of every 
organized being left in a state of nature. The supply of food, on 
an average, remains constant ; yet the tendency in every animal to 
increase by propagation is geometrical ; and its surprising effects 
have nowhere been more astonishingly shown, than in the case 
of the European animals run wild during the last few centuries 
in America. Every animal in a state of nature regularly breeds ; 
yet in a species long established, any great increase in numbers is 
obviously impossible, and must be checked by some means. We 
are, nevertheless, seldom able with certainty to tell in any given 
species, at what period of life, or at what period of the year, or 
whether only at long intervals, the check falls ; or, again, what 
is the precise nature of the check. Hence probably it is, that 
we feel so little surprise at one, of two species closely allied in 
habits, being rare and the other abundant in the same district ; 
or, again, that one should be abundant in one district, and 
another, filling the same place in the economy of nature, should 
be abundant in a neighbouring district, differing very little in its 
conditions. If asked how this is, one immediately replies that 
it is determined by some slight difference in climate, food, or the 
number of enemies : yet how rarely, if ever, we can point out 
the precise cause and manner of action of the check I We are, 
therefore, driven to the conclusion, that causes generally quite 
inappreciable by us, determine whether a given species shall be 
abundant or scanty in numbers. 

In the cases where we can trace the extinction of a species 
through man, either wholly or in one limited district, we know 
that it becomes rarer and rarer, and is then lost : it would be 
difficult to point out any just distinction * between a species 
destroyed by man or by the increase of its natural enemies. The 
evidence of rarity preceding extinction, is more striking in the 
successive tertiary strata, as remarked by several able observers ; 
it has often been found that a shell very common in a tertiary 
stratum is now most rare, and has even long been thought to be 
* See the excellent remarks on this subject by Mr. Lyell, in his Pria 
ciples of Geology. 



176 CAUSES OF EXTIXCTIOX. [CHAP. Tin. 

extinct. If then, as appears probable, species first become rare 
and then extinct if the too rapid increase of every species, even 
the most favoured, is steadily checked, as we must admit, though 
how and when it is hard to say and if we see, without the smallest 
surprise, though unable to assign the precise reason, one species 
abundant and another closely-allied species rare in the same dis- 
trict why should we feel such great astonishment at the rarity 
being carried a step further to extinction ? An action going on, 
on every side of us, and yet barely appreciable, might surely be 
carried a little further, without exciting our observation. Who 
would feel any great surprise at hearing that the Megalonyx was 
formerly rare compared with the Megatherium, or that one of 
the fossil monkeys was few in number compared with one of the 
now living monkeys? and yet in this comparative rarity, we 
should have the plainest evidence of less favourable conditions 
for their existence. To admit that species generally become 
rare before they become extinct to feel no surprise at the com- 
parative rarity of one species with another, and yet to call in 
some extraordinary agent and to marvel greatly when a species 
ceases to exist, appears to me much the same as to admit that 
sickness in the individual is the prelude to death to feel no sur- 
prise at sickness but when the sick man dies to wonder, and 
to believe that he died through violence.

SANTA CRUZ, PATAGONIA, AND THE FALKLAND ISLANDS. 

April 13th, 1834. The Beagle anchored within the mouth of 
the Santa Cruz. This river is situated about sixty miles south of 
Port St. Julian. During the last voyage Captain Stokes pro- 
ceeded thirty miles up it, but then, from the want of provisions, 
was obliged to return. Excepting what was discovered at that 
time, scarcely anything was known about this large river. Cap- 
tain Fitz Roy now determined to follow its course as far as time 
would allow. On the 18th three whale-boats started, carrying 
three weeks' provisions ; and the party consisted of twenty-five 
souls a force which would have been sufficient to have defied a 
host of Indians. With a strong flood-tide and a fine day we 
made a good run, soon drank some of the fresh water, and were 
at night nearly above the tidal influence. 

The river here assumed a size and appearance which, even at 
the highest point we ultimately reached, was scarcely diminished. 
It was generally from three to four hundred yards broad, and in 
the middle about seventeen feet deep. The rapidity of the cur- 
rent, which in its whole course runs at the rate of from four to 
six knots an hour, is perhaps its most remarkable feature. The 
water is of a fine blue colour, but with a slight milky tinge, and 
not so transparent as at first sight would have been expected. 
It flows over a bed of pebbles, like those which compose the 
beach and the surrounding plains. It runs in a winding course 
through a valley, which extends in a direct line westward. This 



178 S. CRUZ, PATAGONIA. [CHAP. rx. 

valley varies from five to ten miles in breadth ; it is bounded by 
step-formed terraces, which rise in most parts, one above the 
other, to the height of five hundred feet, and have on the oppo- 
site sides a remarkable correspondence. 

April 19th. Against so strong a current it was, of course, 
quite impossible to row or sail : consequently the three boats 
were fastened together head and stern, two hands left in each, 
and the rest came on shore to track. As the general arrange- 
ments made by Captain Fitz Roy were very good for facilitating 
the work of all, and as all had a share in it, I will describe the 
system. The party, including every one, was divided into two 
spells, each of which hauled at the tracking line alternately for 
an hour and a half. The officers of each boat lived with, ate the 
same food, and slept in the same tent with their crew, so that 
each boat was quite independent of the others. After sunset the 
first level spot where any bushes were growing, was chosen for 
our night's lodging. Each of the crew took it in turns to be 
cook. Immediately the boat was hauled up, the cook made his 
fire ; two others pitched the tent ; the coxswain handed the 
things out of the boat ; the rest carried them up to the tents and 
collected firewood. By this order, in half an hour everything 
was ready for the night. A watch of two men and an officer 
was always kept, whose duty it was to look after the boats, keep 
up the fire, and guard against Indians. Each in the party had 
his one hour every night. 

During this day we tracked but a short distance, for there 
were many islets, covered by thorny bushes, and the channels 
between them were shallow. 

April 20th. We passed the islands and set to work. Oui 
regular day's march, although it was hard enough, carried us on 
an average only ten miles in a straight line, and perhaps fifteen 
or twenty altogether. Beyond the place where we slept last 
night, the country is completely terra incognita, for it was there 
that Captain Stokes turned back. We saw in the distance a 
great smoke, and found the skeleton of a horse, so we knew that 
Indians were in the neighbourhood. On the next morning (21st) 
tracks of a party of horse, and marks left by the trailing of the 
chuzos, or long spears, were observed on the ground. It was 
generally thought that the Indians had reconnoitred us during 



1834.] ZOOLOGY. 179 

the night. Shortly afterwards 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 22d. The country remained the same, and was ex- 
tremely uninteresting. The complete similarity of the produc- 
tions throughout 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. Everywhere 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 tine 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 abun- 
Jant, 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 river ; and the remains 
of several guanacos, with their necks dislocated and bones broken, 
showed how they had met their death. 

April 24th. Like the navigators of old when approaching an 
unknown land, we examined and watched for the most trivial 

* The deserts of Syria are characterized, according to Volney (torn, i., 
p. 351), by woody bushes, numerous rats, gazelles, and hares. In the land-

sign of a change. The drifted trunk of a tree, or a boulder of 
primitive rock, was hailed with joy, as if we had seen a forest 
growing on the flanks of the Cordillera. The top, however, of a 
heavy bank of clouds, which remained almost constantly in one 
position, was the most promising sign, and eventually turned out 
a true harbinger. At first the clouds were mistaken for the moun- 
tains themselves, instead of the masses of vapour condensed by 
their icy summits. 

April 26th. 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 we saw, at the dis- 
tance 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 moun- 
tains of that great chain for its source ; and worthy of such a source 
are streams, that have flowed over the gently inclined bed of thr 



1834.] EXCAVATION OF THE VALLEY. 181 

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 evi- 
dent that the strata once were 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 hun- 
dred feet, and a breadth varying from rather less than two miles 
to four miles ? The river, though it has so little power in trans- 
porting 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 argu- 
ments 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-hillocks 
on it, and from the occurrence of a few sea-shells lying in the 
bed of the river. If I had space I could prove that South Ame- 
rica was formerly here cut off by a strait, joining the Atlantic 
and Pacific oceans, like that of Magellan. But it may yet be 
asked, how has the solid basalt been removed? Geologists 
formerly would have brought into play, the violent action of 
some overwhelming 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 has 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 cor- 
roded so vast an area and thickness of solid basaltic lava. Ne- 
vertheless, we must believe that the strafa undermined by the 
waters of this ancient strait. wc"-e broken up into huge frag-

ments, and these lying scattered on the beach, were reduced first 
to smaller blocks, then to pebbles, and lastly to the most impal- 
pable mud, which the tides drifted far into the Eastern or 
Western Ocean. 

With the change in the geological structure of the plains the 
character of the landscape likewise altered. While rambling 
up some of the narrow and rocky defiles, I could almost have 
fancied myself transported back again to the barren valleys 01 
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 cir- 
cumscribed patches of bright green herbage. 

April 21th. 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 N. of the 
equator. The steep cliff near the mouth of the Rio 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 condor is not 
uncommon ; yet only a few stragglers occasionally visit the sea- 
coast. A line of cliff near the mouth of the Santa Cruz is fre- 
quented by these birds, and about eighty miles up the river, 
where the sides of the valley are formed by steep basaltic pre- 
cipices, 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 tlif 



1834.] THE CONDOR. 



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 in- 
accessible 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 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 ba- 
saltic cliffs of the Santa Cruz, I found a spot, where scores must 
usually haunt. On coming suddenly to the brow of the preci- 
pice, 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 gregarious bird. In this 
part of the country they live altogether on the guanacos which 
have died a natural death, or, as more commonly 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 excur- 
sions 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 occa- 
sions 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 con- 
dors frequently attack young goats and lambs ; and the shep- 
nerd 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 car- 
cass on a level piece of ground within an enclosure of sticks with 
an opening, and when the condors are gorged, to gallop up OD 

13 



184 S. CRUZ, PATAGOXIA. [CHAP. ix. 

horseback to the entrance, and thus enclose them : for when this 
bird has not space to run, it cannot give its body sufficient mo- 
mentum to rise from the ground. The second method is to mark 
the trees in which, frequently to the number of five or six toge- 
ther, 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 is eight or ten 
shillings. One which I saw brought in, had been tied with 
rope, and was much injured ; yet, the moment the line 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 ex- 
periment, 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. Remembering 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 

* I noticed that several hours before any one of the condors died, all the 
lice, with which it was infested, crawled tc the outside feathers. I was 
issnreil that this alwavs happened.

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 singu- 
larly balanced. Professor Owen lias demonstrated that the olfac- 
tory nerves of the turkey -buzzaid (Cathartes aura) are highly 
developed ; and on the evening when Mr. Owen's paper was read 
at the Zoological Society, it was mentioned by a gentleman that 
he had seen the carrion-hawks in the West Indies on two occa- 
sions collect on the roof of a house, when a corpse had become 
offensive from not having been buried : in this case, the intelli- 
gence could hardly have been acquired by sight. On the other 
hand, besides the experiments of Audubon and that one by my- 
self, Mr. Bachman has tried in the United States many varied 
plans, showing that neither the turkey-buzzard (the species dis- 
sected by Professor Owen) nor the gallinazo find their food by 
smell. He covered portions of highly offensive offal with a thin 
canvass 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 dis- 
covering it. A small rent was made in the canvass, and the offal 
was immediately discovered ; the canvass 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 MY. 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 ho- 
rizon, 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 over- 
looked? 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 descen!

proclaim throughout the district to the whole family of carrion- 
feeders, that their prey is ak 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 in- 
tently watched from an oblique position, the outlines of the sepa- 
rate 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 ; but they were seen dis- 
tinct against the blue sky. The head and neck were moved fre- 
quently, and apparently with force ; and the extended wings 
seemed to form the fulcrum on which the movements 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 soar- 
ing, its motion must be sufficiently rapid, so that the action of 
the inclined surface of its body on the atmosphere may counter- 
balance its gravity. Tho 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 
vanted. The movement 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. 

April 29th. From some high land we hailed with joy the 
white summits of the Cordillera, as they were seen occasionally 
peeping through their dusky envelope of clouds. During the 
few succeeding days we continued to get on slowly, for we found 
the river-course very tortuous, and strewed with immense frag- 
ments of various ancient slaty rocks, and of granite. The plain 
bordering the valley had here attained an elevation of about 



1831.] TRACES OF INDIANS. 187 

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 circumstances 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 
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 chace. Nevertheless, in two places 
in this very central region, I fouud 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. 

May 4th. Captain Fitz Roy 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 pro- 
ceed any further. Everywhere we met with the same produc- 
tions, and the same dreary landscape. We were now one hun- 
dred 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 wide basin, bounded on the north and south 
by the basaltic platforms, and fronted by the long range of the 
snow-clad Cordillera. But we viewed these grand mountaiaf 



188 FALKLAND ISLANDS. [CHAP, ix 

with regret, for we were obliged to imagine their nature and pro- 
ductions, instead of standing, 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 often 
knots an hour. In this one day we effected what had cost us 
five-and-a-half hard days' labour in ascending. On the 8th, we 
reached the Beagle after our twenty-one days' expedition. Every 
one, excepting myself, had cause to be dissatisfied ; but to rne 
the ascent afforded a most interesting section of the great tertiary 
formation of Patagonia. 



On March 1st, 1833, and again on March 16th, 1834, the Beagle 
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, unsupported by any power : and when we ar- 
rived, 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 undulat- 
ing land, 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 



CHAP, ix.] HUNTING WILD CATTLE. 189 

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.* 

16th. 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-storms. 
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 co- 
vered 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 be seen a small flock of wild geese, and every- 
where the ground was so soft that the snipe were able to feed. 
Besides these two birds there were few others. There is one 
main range of hills, nearly two thousand feet in height, and com- 
posed 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, foi 
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 entan- 
gled. Then dropping his hat to mark the spot where the balls 
were left, while at full gallop, he uncoiled his lazo, and after a 
most severe chace, 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 

* 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 1 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 aud dry as it has lately been repre- 
sented 



190 FALKLAND ISLANDS. [CHAP. rx. 

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 ; other- 
wise, it stands motionless leaning on one side. This horse, how- 
ever, was a young one, and would not stand still, but ga^ e in to 
the cow as she struggled. It was admirable to see with what 
dexterity St. Jago dodged behind the beast, till at last he con- 
trived 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 com- 
mon 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 supped 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 
stormy, with much hail and snow. We 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 mag- 
nificent beasts ; 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 
k 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 
Worses 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 failing, were obliged to make a 
large circuit. The Gauchos in revenge determined to emasculate 



CHAP, ix.] WILD HORSES. 191 

him and render him for the future harmless. It was very inter- 
esting to see how art completely mastered force. One lazo was 
thrown over his horns as he rushed at the horse, and another 
round his hind legs : in a minute the monster was stretched 
powerless on the ground. After the lazo has once been drawn 
tightly round the horns of a furious animal, it does not at fir.it 
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- 
aclf. 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 1764, 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 pre- 
vent 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, ex- 
cept from the strong attachment which horses have to any loca- 
lity 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. S^livan 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 com- 
pelling the mares 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 
Rnd biting a mare till he forced her to leave her foal to its late. 
Capt. Sulivan can so far corroborate this curious account, that 



192 FALKLAND ISLANDS. [CHAP. ix. 

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 oi 
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 in- 
forms 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. Round 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 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 
ill probability ultimately prevail over the others, if the herds 
were left undisturbed for the next several centuries. 



CHAP, ix.] WILD RABBITS. 193 

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 ihey have not crossed the central chain of 
hills, 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 ao 
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 tc 
contend against pre-existing enemies, in the fox and some large 
hawks. The French naturalists have considered the black va- 
riety a distinct species, and called it Lepus Magellanicus.* They 
imagined that Magellan, when talking of an animal under the 
name of ' conejos' in the Strait of Magellan, referred to this 
species; but he was alluding to a small cavy, which to this day 
is thus 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 off- 
spring. Of the latter I now possess a specimen, and it is marked 
about the head differently from the French specific description. 
This circumstance 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 f is a large wolf-like 
fox (Canis antarcticus), which is common to both East and 

* 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 ears. I may here observe that 
the difference between the Irish and English hare rests upon nearly similar 
characters, only more strongly marked. 

t 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 settlers. The common hog has also run wild on one islet : all are of a 
black colour : the boars are very fierce, aud have great tusks. 



194 FALKLAND ISLANDS. [CHAP. ix. 

West Falkland. 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 ;" * but I have seen both, and they are quite distinct. 
These wolves are well known, from Byron's account of their 
lameness 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 num- 
bers 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 
the flesh had been picked by the carrion-hawks. They told me 
that in winter they often killed a beast, cleaned the flesh from the 
bones with theii 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 

* The "culpeu" is the Cauls Magellanicus brought home by Captain 
King from the Strait of Magellan, it is common in Chile. 



CHAP, ix.] ART IN MAKING A FIRE. 195 

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 abso- 
lutely 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 Composite) 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, immedi- 
ately 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 
bird's 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, and 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 out hunting wild cattle, and in consequence, 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 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 



196 FALKLAND ISLANDS. [CHAP. ix. 

treatment, being too much terrified to leave the herd, they ar 
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 Ruins, 
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 sandstone, 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 
covered in an extraordinary manner by myriads of great locse an- 
gular 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, theii 
* Pernety, Voyage aux Isles Malouines, p. 526 



CHAP, ix.] STREAMS OF STONES. 197 

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 pos- 
sible to ascertain their thickness, but the water of small stream- 
lets 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 en- 
croaches 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 was 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 con- 
tinuous stream of these fragments followed up the course of a 
valley, and even extended 1o 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," which immediately occurred to every one, 
conveys the same idea. These scenes are on the spot rendered 



198 FALKLAND ISLANDS. [CHAP. ix. 

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 trans- 
verse section within these valleys, the bottom is nearly level, or 
rises but 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 move- 
ment of overwhelming force,* the fragments have been levelled 
into one continuous sheet. If during the earthquake"]" which in 
1835 overthrew Concepcion, in Chile, it was thought wonderful 
that small bodies should have 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 stupen- 
dous mountains have been broken into pieces like so much 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 counterpart: 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. 

I have little to remark on the zoology of these islands. 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 brave 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. 
Wh^n crawling, it may be said on four legs, through the tus- 
sucks 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 Falklarids. The upland 
species (Anas Magellanica) is common, in pairs and in small 
tlocks, throughout the island. They do not migrate, but build 
14 



200 FALKLAND ISLANDS. [CHAP. ix. 



on the small ourlying 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), is common both here and on the west coast oi 
America, as far north as Chile. In the deep and retired channels 
of Tierra del Fuego, the snow-white gander, invariably accom- 
panied 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 Apteryx 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 sur- 
prisingly heavy and strong : the head is so strong that I have 
scarcely been able to fracture it with my geological hammer ; 
and all our pportsmen 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 



CHAP, ix.] ZOOPHYTES. 201 

many observations on the lower marine animals,* but they are 
of little general interest. I will mention only one class of tacts, 
relating to certain zoophytes in the more highly organized divi- 
sion 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 move- 
ment, 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 evi- 
dently 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 a 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 fur- 
nished 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 

* 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 two 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 ad- 
hered by its edge to the rock in an oval spire. One which I found, mea- 
sured 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, 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 
rutmbers of an individual species depend on its powers of propagation. 



202 FALKLAND ISLANDS. [CHAP. ix. 

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 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 01 
flower-buds. 

In another elegant little coralline (Crisia?), eac'h 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 zoo- 
phyte, 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 Baliia Blanca. I will state one other in- 
stance of uniform action, though of a very different nature, in a 
zoophyte closely allied to Clytia, and therefore very simply or- 
ganized. 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 



CHAP, ix.] COMPOUND ANIMALS. 203 

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 move- 
ment 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 that the union of separate individuals in 
a common body is more striking in a coralline than in a tree. 
Our conception of a compound animal, where in some respects 
the individuality of each is not completed, may be aided, by re- 
flecting 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 pro- 
pagated by buds seem more intimately related to each other, than 
eggs or seeds are to their parents. It seems now pretty well esta- 
blished 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.

TIERRA DEL FUEGO. 

December 17th, 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, inhos- 
pitable Staten-land was visible amidst the clouds. In the after- 
noon 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 en- 
tangled 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 any thing 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 
the Fuegians. When we came within hail, one of the four 
natives who were present advanced to receive us, and began to 



CHAP, x.] INTERVIEW WITH THE NATIVES. 205 

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 dif- 
ference 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 improvement. 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 Patago- 
nians 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 ear 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 chuck- 
ling kind of noise, as people do when feeding chickens. I 
walked with 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 



206 TIERRA DEL FUEGO. [CHAP. x. 

articulate. Captain Cook has compared it to a man clearing his 
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 remem- 
bered 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 ol 
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 recognised. How can 
this faculty be explained ? is it a consequence of the more prac- 
tised 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 do\vn 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 Europeans 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 Roy 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 thorn and 



CHAP, x.] FUEGIANS OX BOARD. 207 

instruct them in religion at his own expense. To settle these 
natives in their own country, was one chief inducement to Cap- 
tain Fitz Roy to undertake our present voyage ; and before the 
Admiralty had resolved to send out this expedition, Captain 
Fitz Roy had generously chartered a vessel, and would himself 
have taken them back. The natives were accompanied by a mis- 
sionary, R. Matthews ; of whom and of the natives, Captain Fitz 
Roy has published a full and excellent account. Two men, ono 
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, taci- 
turn, morose, and when excited violently passionate ; his aftec- 
tions were very strong towards a few friends on board ; his intel- 
lect 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 remark- 
ably sympathetic with any one in pain : when the water was 
rough, 1 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 appearance ; 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 look- 
ing-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 good qualities, that he should have been of the same 
race, and doubtless partaken of the same character, with the mi- 



208 TIERRA DEL FUEGO. [CHAP. x. 

arable, 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 
'earning anything, especially languages. This she showed in 
picking up some Portuguese and Spanish, when 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. 

Althou
