BUENOS AYRES TO ST. FÉ.

_September_ 27_th._—In the evening I set out on an excursion to St. Fé,

which is situated nearly three hundred English miles 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 waggons 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_ 28_th._—We passed the small town of Luxan, where there is a

wooden bridge over the river—a most unusual convenience in this

country. We passed also Areco. The plains appeared level, but were not

so in fact; for in various places the horizon was distant. The

estancias are here wide apart; for there 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 and 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 robbers 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[1] 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 prefers a

clayey or sandy soil, which produces a different and more abundant

vegetation. Near Mendoza, at the foot of the Cordillera, it occurs in

close neighbourhood with the allied alpine species. It is a very

curious circumstance in its geographical distribution, that it has

never been seen, fortunately for the inhabitants of Banda Oriental, to

the eastward of the river Uruguay: yet in this province there are

plains which appear admirably adapted to its habits. The Uruguay has

formed an insuperable obstacle to its migration: although the broader

barrier of the Parana has 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 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. Their flesh, when

cooked, is very white and good, but it is seldom used.

[1] 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.

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,

etc., 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 anywhere near its

habitation must cost much trouble. For what purpose it is done, I am

quite unable to form even the most remote 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 Calodera

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 coloured ones. Mr. Gould,

who has described these facts, informs 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 cunicularia), which has been so often 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 frequently 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

stomachs 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. I 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[2] there is a fishing genus of owls, which likewise

catches crabs.

[2] _Journal of Asiatic Soc._, vol. v, p. 363.

In the evening we crossed the Rio Arrecife on a simple raft made of

barrels lashed together, and slept at the post-house on the other side.

I 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.

29_th and_ 30_th._—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. Rozario 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 absolutely

perpendicular, and of a red colour; at other times in large 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.

[Illustration]

For many leagues north and south of San Nicolas and Rozario, the

country is really level. Scarcely anything which travellers 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 distant. 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.

[Illustration]

_October_ 1_st._—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, I 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

inhabited 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_ 2_nd._—We passed through Corunda, which, from the luxuriance

of its gardens, was one of the prettiest villages I saw. From this

point to St. Fé 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. Fé. 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 from 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_ 3_rd and_ 4_th._—I was confined for these two days to my bed

by a headache. 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 headache 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. Fé 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. 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_ 5_th._—We crossed the Parana to St. Fé 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 is the

capital of Entre Rios. 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

representatives, 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 examining the

geology of the surrounding country, which was very interesting. We here

see at the bottom of the cliffs, beds containing 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 Punta Gorda, in

Banda Oriental, I found an alternation of the Pampæan 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 probably an

oscillation of level in the bottom of the ancient estuary. Until

lately, my reasons for considering the Pampæan 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 Professor Ehrenberg 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 Pampæan 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,[3] and I 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 characterising it, until he thought of

comparing 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 lived and disappeared, to

be succeeded in after ages by the countless herds descended from the

few introduced with the Spanish colonists!

[3] I need hardly state here that there is good evidence against any

horse living in America at the time of Columbus.

[Illustration]

The existence in South America of a fossil horse, of the mastodon,

possibly of an elephant,[4] 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 geographical distribution of animals. At the

present time, if we divide America, not by the Isthmus of Panama, but

by the southern part of Mexico[5] 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 wanderers from the

south, such as the puma, opossum, kinkajou, and peccari. South America

is characterised by possessing many peculiar gnawers, a family of

monkeys, the llama, peccari, tapir, opossums, and, especially, several

genera of Edentata, the order which includes the sloths, ant-eaters,

and armadilloes. North America, on the other hand, is characterised

(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 elephant, mastodon, horse, and

three genera of Edentata, namely, the Megatherium, Megalonyx, and

Mylodon. Within nearly this same period (as proved by the shells at

Bahia Blanca) South America possessed, as we have 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. 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-characterised 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 recent submergence of land

in the West Indian Archipelago, as the cause of the present zoological

separation of North and South America. The South American character of

the West Indian mammals[6] seems to indicate that this archipelago was

formerly united to the southern continent, and that it has subsequently

been an area of subsidence.

[4] Cuvier, _Ossemens Fossils_, tome i, p. 158.

[5] This is the geographical division followed by Lichtenstein,

Swainson, 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 British 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, of a rodent animal

being common to North and South America.”

[6] See Dr. Richardson’s _Report_, p. 157; also _L’Institut_, 1837, p.

253. Cuvier says the kinkajou is found in the larger Antilles, but

this is doubtful. M. Gervais states that the Didelphis crancrivora is

found there. It is certain that the West Indies possess some mammifers

peculiar to themselves. A tooth of a mastodon has been brought from

Bahama; _Edinburgh New Philosophical Journal_, 1826, p. 395.

[Illustration]

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 Straits[7] 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 hollow-horned

ruminants migrated, on land since submerged near Behring’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.

[7] See the admirable Appendix by Dr. Buckland to Beechey’s _Voyage_;

also the writings of Chamisso in Kotzebue’s _Voyage._

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 the “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. Fé. 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[8] used to come into his courtyard to the well, which

he had been obliged to dig to supply his own family with water; 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

previously to these years 20,000 cattle; at the end not one remained.

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 commission 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 eye-witness 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

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[9]

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 1832, 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?[10]

[8] In Captain Owen’s _Surveying Voyage_ (vol. ii, p. 274) there is a

curious 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 invaders, but not until

they had killed one man, and wounded several others.” The town is said

to have a population of nearly three thousand! Dr. Malcolmson 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.)

[9] _Travels_, vol. i, p. 374.

[10] These droughts to a certain degree seem to be almost periodical;

I was told the dates of several others, and the intervals were about

fifteen years.

_October_ 12_th._—I had intended to push my excursion farther, 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 of the islands. The Parana is full of

islands, which undergo a constant 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 about four

feet above the level of the river; but during the periodical floods

they are inundated. They all present one character; numerous willows

and a few other trees are bound together 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 pleasure 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. Fé: 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.

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 moorings. 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_ 15_th._—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 narrow arm of the river. I took the boat

and rowed some distance 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.

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 on the grassy plains,

at some distance from the water. Being at anchor, as I have said, in

one of the deep creeks between 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

irregular 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 mactræ buried in the sand-banks on the coast of Chile:

from their weak bills, with the lower mandible so much projecting,

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 kingfisher (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 the 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-fields. 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 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 common 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_ 16_th._—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.

18_th and_ 19_th._—We continued slowly to sail 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 destitute 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 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 unnatural calm.

That country will have to learn, like every other South American state,

that a republic cannot succeed till it contains a certain body of men

imbued with the principles of justice and honour.

_October_ 20_th._—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 permission 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 general 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 very 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

sentinels. 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 looking 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 attached 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 men 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 the plans of his

party. A year ago he was elected governor, but he refused it, unless

the Sala would also confer on him extraordinary 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.
