NORTHERN CHILE AND PERU.
_April_ 27_th._—I set out on a journey to Coquimbo, and thence through
Guasco to Copiapó, where Captain Fitz Roy kindly offered to pick me up
in the _Beagle._ The distance in a straight line along the shore
northward is only 420 miles; but my mode of travelling made it a very
long journey. I bought
four horses and two mules, the latter carrying the luggage on alternate
days. The six animals together only cost the value of twenty-five
pounds sterling, and at Copiapó I sold them again for twenty-three. We
travelled in the same independent manner as before, cooking our own
meals, and sleeping in the open air. As we rode towards the Viño del
Mar, I took a farewell view of Valparaiso, and admired its picturesque
appearance. For geological purposes I made a detour from the high road
to the foot of the Bell of Quillota. We passed through an alluvial
district rich in gold, to the neighbourhood of Limache, where we slept.
Washing for gold supports the inhabitants of numerous hovels, scattered
along the sides of each little rivulet; but, like all those whose gains
are uncertain, they are unthrifty in their habits, and consequently
poor.
28_th._—In the afternoon we arrived at a cottage at the foot of the
Bell mountain. The inhabitants were freeholders, which is not very
usual in Chile. They supported themselves on the produce of a garden
and a little field, but were very poor. Capital is here so deficient
that the people are obliged to sell their green corn while standing in
the field, in order to buy necessaries for the ensuing year. Wheat in
consequence was dearer in the very district of its production than at
Valparaiso, where the contractors live. The next day we joined the main
road to Coquimbo. At night there was a very light shower of rain: this
was the first drop that had fallen since the heavy rain of September
11th and 12th, which detained me a prisoner at the Baths of Cauquenes.
The interval was seven and a half months; but the rain this year in
Chile was rather later than usual. The distant Andes were now covered
by a thick mass of snow, and were a glorious sight.
_May_ 2_nd._—The road continued to follow the coast at no great
distance from the sea. The few trees and bushes which are common in
central Chile decreased rapidly in numbers, and were replaced by a tall
plant, something like a yucca in appearance. The surface of the
country, on a small scale, was singularly broken and irregular; abrupt
little peaks of rock rising out of small plains or basins. The indented
coast and the bottom of the neighbouring sea, studded with breakers,
would, if converted into dry land, present similar forms; and
such a conversion without doubt has taken place in the part over which
we rode.
3_rd._—Quilimari to Conchalee. The country became more and more barren.
In the valleys there was scarcely sufficient water for any irrigation;
and the intermediate land was quite bare, not supporting even goats. In
the spring, after the winter showers, a thin pasture rapidly springs
up, and cattle are then driven down from the Cordillera to graze for a
short time. It is curious to observe how the seeds of the grass and
other plants seem to accommodate themselves, as if by an acquired
habit, to the quantity of rain which falls upon different parts of this
coast. One shower far northward at Copiapó produces as great an effect
on the vegetation, as two at Guasco, and three or four in this
district. At Valparaiso a winter so dry as greatly to injure the
pasture, would at Guasco produce the most unusual abundance. Proceeding
northward, the quantity of rain does not appear to decrease in strict
proportion to the latitude. At Conchalee, which is only 67 miles north
of Valparaiso, rain is not expected till the end of May; whereas at
Valparaiso some generally falls early in April: the annual quantity is
likewise small in proportion to the lateness of the season at which it
commences.
4_th._—Finding the coast-road devoid of interest of any kind, we turned
inland towards the mining district and valley of Illapel. This valley,
like every other in Chile, is level, broad, and very fertile: it is
bordered on each side, either by cliffs of stratified shingle, or by
bare rocky mountains. Above the straight line of the uppermost
irrigating ditch, all is brown as on a high-road; while all below is of
as bright a green as verdigris, from the beds of alfarfa, a kind of
clover. We proceeded to Los Hornos, another mining district, where the
principal hill was drilled with holes, like a great ants’-nest. The
Chilian miners are a peculiar race of men in their habits. Living for
weeks together in the most desolate spots, when they descend to the
villages on feast-days there is no excess of extravagance into which
they do not run. They sometimes gain a considerable sum, and then, like
sailors with prize-money, they try how soon they can contrive to
squander it. They drink excessively, buy quantities of clothes, and in
a few days return penniless to their miserable abodes, there to work
harder
than beasts of burden. This thoughtlessness, as with sailors, is
evidently the result of a similar manner of life. Their daily food is
found them, and they acquire no habits of carefulness; moreover,
temptation and the means of yielding to it are placed in their power at
the same time. On the other hand, in Cornwall, and some other parts of
England, where the system of selling part of the vein is followed, the
miners, from being obliged to act and think for themselves, are a
singularly intelligent and well-conducted set of men.
The dress of the Chilian miner is peculiar and rather picturesque. He
wears a very long shirt of some dark-coloured baize, with a leathern
apron; the whole being fastened round his waist by a bright-coloured
sash. His trousers are very broad, and his small cap of scarlet cloth
is made to fit the head closely. We met a party of these miners in full
costume, carrying the body of one of their companions to be buried.
They marched at a very quick trot, four men supporting the corpse. One
set having run as hard as they could for about two hundred yards, were
relieved by four others, who had previously dashed on ahead on
horseback. Thus they proceeded, encouraging each other by wild cries:
altogether the scene formed a most strange funeral.
We continued travelling northward in a zigzag line; sometimes stopping
a day to geologise. The country was so thinly inhabited, and the track
so obscure, that we often had difficulty in finding our way. On the
12th I stayed at some mines. The ore in this case was not considered
particularly good, but from being abundant it was supposed the mine
would sell for about thirty or forty thousand dollars (that is, 6000 or
8000 pounds sterling); yet it had been bought by one of the English
Associations for an ounce of gold (£3 : 8s). The ore is yellow pyrites,
which, as I have already remarked, before the arrival of the English
was not supposed to contain a particle of copper. On a scale of profits
nearly as great as in the above instance, piles of cinders, abounding
with minute globules of metallic copper, were purchased; yet with these
advantages, the mining associations, as is well known, contrived to
lose immense sums of money. The folly of the greater number of the
commissioners and shareholders amounted to infatuation;—a thousand
pounds per annum given in some
cases to entertain the Chilian authorities; libraries of well-bound
geological books; miners brought out for particular metals, as tin,
which are not found in Chile; contracts to supply the miners with milk,
in parts where there are no cows; machinery, where it could not
possibly be used; and a hundred similar arrangements, bore witness to
our absurdity, and to this day afford amusement to the natives. Yet
there can be no doubt, that the same capital well employed in these
mines would have yielded an immense return: a confidential man of
business, a practical miner and assayer, would have been all that was
required.
Captain Head has described the wonderful load which the “Apires,” truly
beasts of burden, carry up from the deepest mines. I confess I thought
the account exaggerated; so that I was glad to take an opportunity of
weighing one of the loads, which I picked out by hazard. It required
considerable exertion on my part, when standing directly over it, to
lift it from the ground. The load was considered under weight when
found to be 197 pounds. The apire had carried this up eighty
perpendicular yards,—part of the way by a steep passage, but the
greater part up notched poles, placed in a zigzag line up the shaft.
According to the general regulation, the apire is not allowed to halt
for breath, except the mine is six hundred feet deep. The average load
is considered as rather more than 200 pounds, and I have been assured
that one of 300 pounds (twenty-two stone and a half) by way of a trial
has been brought up from the deepest mine! At this time the apires were
bringing up the usual load twelve times in the day; that is 2400 pounds
from eighty yards deep; and they were employed in the intervals in
breaking and picking ore.
These men, excepting from accidents, are healthy, and appear cheerful.
Their bodies are not very muscular. They rarely eat meat once a week,
and never oftener, and then only the hard dry charqui. Although with a
knowledge that the labour was voluntary, it was nevertheless quite
revolting to see the state in which they reached the mouth of the mine;
their bodies bent forward, leaning with their arms on the steps, their
legs bowed, their muscles quivering, the perspiration streaming from
their faces over their breasts, their nostrils distended, the corners
of their mouth forcibly drawn back, and the expulsion of their
breath most laborious. Each time they draw their breath they utter an
articulate cry of “ay-ay,” which ends in a sound rising from deep in
the chest, but shrill like the note of a fife. After staggering to the
pile of ore, they emptied the “carpacho;” in two or three seconds
recovering their breath, they wiped the sweat from their brows, and
apparently quite fresh descended the mine again at a quick pace. This
appears to me a wonderful instance of the amount of labour which habit,
for it can be nothing else, will enable a man to endure.
In the evening, talking with the _mayor-domo_ of these mines about the
number of foreigners now scattered over the whole country, he told me
that, though quite a young man, he remembers when he was a boy at
school at Coquimbo, a holiday being given to see the captain of an
English ship, who was brought to the city to speak to the governor. He
believes that nothing would have induced any boy in the school, himself
included, to have gone close to the Englishman; so deeply had they been
impressed with an idea of the heresy, contamination, and evil to be
derived from contact with such a person. To this day they relate the
atrocious actions of the bucaniers; and especially of one man, who took
away the figure of the Virgin Mary, and returned the year after for
that of St. Joseph, saying it was a pity the lady should not have a
husband. I heard also of an old lady who, at a dinner at Coquimbo,
remarked how wonderfully strange it was that she should have lived to
dine in the same room with an Englishman; for she remembered as a girl,
that twice, at the mere cry of “Los Ingleses,” every soul, carrying
what valuables they could, had taken to the mountains.
14_th._—We reached Coquimbo, where we stayed a few days. The town is
remarkable for nothing but its extreme quietness. It is said to contain
from 6000 to 8000 inhabitants. On the morning of the 17th it rained
lightly, the first time this year, for about five hours. The farmers,
who plant corn near the sea-coast where the atmosphere is more humid,
taking advantage of this shower, would break up the ground; after a
second they would put the seed in; and if a third shower should fall,
they would reap a good harvest in the spring. It was interesting to
watch the effect of this trifling amount of moisture. Twelve hours
afterwards the ground appeared as dry as ever; yet after an interval of
ten days all the hills were faintly tinged with green
patches; the grass being sparingly scattered in hair-like fibres a full
inch in length. Before this shower every part of the surface was bare
as on a high-road.
Coquimbo, Chile
In the evening, Captain Fitz Roy and myself were dining with Mr.
Edwards, an English resident well known for his hospitality by all who
have visited Coquimbo, when a sharp earthquake happened. I heard the
forecoming rumble, but from the screams of the ladies, the running of
the servants, and the rush of several of the gentlemen to the doorway,
I could not distinguish the motion. Some of the women afterwards were
crying with terror, and one gentleman said he should not be able to
sleep all night, or if he did, it would only be to dream of falling
houses. The father of this person had lately lost all his property at
Talcahuano, and he himself had only just escaped a falling roof at
Valparaiso in 1822. He mentioned a curious coincidence which then
happened: he was playing at cards, when a German, one of the party, got
up, and said he would never sit in a room in these countries with the
door shut, as, owing to his having done so, he had nearly lost his life
at Copiapó.
Accordingly he opened the door; and no sooner had he done this, than he
cried out, “Here it comes again!” and the famous shock commenced. The
whole party escaped. The danger in an earthquake is not from the time
lost in opening the door, but from the chance of its becoming jammed by
the movement of the walls.
It is impossible to be much surprised at the fear which natives and old
residents, though some of them known to be men of great command of
mind, so generally experience during earthquakes. I think, however,
this excess of panic may be partly attributed to a want of habit in
governing their fear, as it is not a feeling they are ashamed of.
Indeed, the natives do not like to see a person indifferent. I heard of
two Englishmen who, sleeping in the open air during a smart shock,
knowing that there was no danger, did not rise. The natives cried out
indignantly, “Look at those heretics, they do not even get out of their
beds!”
I spent some days in examining the step-formed terraces of shingle,
first noticed by Captain B. Hall, and believed by Mr. Lyell to have
been formed by the sea during the gradual rising of the land. This
certainly is the true explanation, for I found numerous shells of
existing species on these terraces. Five narrow, gently sloping,
fringe-like terraces rise one behind the other, and where best
developed are formed of shingle: they front the bay, and sweep up both
sides of the valley. At Guasco, north of Coquimbo, the phenomenon is
displayed on a much grander scale, so as to strike with surprise even
some of the inhabitants. The terraces are there much broader, and may
be called plains, in some parts there are six of them, but generally
only five; they run up the valley for thirty-seven miles from the
coast. These step-formed terraces or fringes closely resemble those in
the valley of S. Cruz, and, except in being on a smaller scale, those
great ones along the whole coast-line of Patagonia. They have
undoubtedly been formed by the denuding power of the sea, during long
periods of rest in the gradual elevation of the continent.
Shells of many existing species not only lie on the surface of the
terraces at Coquimbo (to a height of 250 feet), but are embedded in a
friable calcareous rock, which in some places is
as much as between twenty and thirty feet in thickness, but is of
little extent. These modern beds rest on an ancient tertiary formation
containing shells, apparently all extinct. Although I examined so many
hundred miles of coast on the Pacific, as well as Atlantic side of the
continent, I found no regular strata containing sea-shells of recent
species, excepting at this place, and at a few points northward on the
road to Guasco. This fact appears to me highly remarkable; for the
explanation generally given by geologists, of the absence in any
district of stratified fossiliferous deposits of a given period,
namely, that the surface then existed as dry land, is not here
applicable; for we know from the shells strewed on the surface and
embedded in loose sand or mould, that the land for thousands of miles
along both coasts has lately been submerged. The explanation, no doubt,
must be sought in the fact, that the whole southern part of the
continent has been for a long time slowly rising; and therefore that
all matter deposited along shore in shallow water must have been soon
brought up and slowly exposed to the wearing action of the sea-beach;
and it is only in comparatively shallow water that the greater number
of marine organic beings can flourish, and in such water it is
obviously impossible that strata of any great thickness can accumulate.
To show the vast power of the wearing action of sea-beaches, we need
only appeal to the great cliffs along the present coast of Patagonia,
and to the escarpments or ancient sea-cliffs at different levels, one
above another, on that same line of coast.
The old underlying tertiary formation at Coquimbo appears to be of
about the same age with several deposits on the coast of Chile (of
which that of Navedad is the principal one), and with the great
formation of Patagonia. Both at Navedad and in Patagonia there is
evidence, that since the shells (a list of which has been seen by
Professor E. Forbes) there intombed were living, there has been a
subsidence of several hundred feet, as well as an ensuing elevation. It
may naturally be asked how it comes that although no extensive
fossiliferous deposits of the recent period, nor of any period
intermediate between it and the ancient tertiary epoch, have been
preserved on either side of the continent, yet that at this ancient
tertiary epoch, sedimentary matter containing fossil remains should
have been deposited and preserved at different points in north and
south
lines, over a space of 1100 miles on the shores of the Pacific, and of
at least 1350 miles on the shores of the Atlantic, and in an east and
west line of 700 miles across the widest part of the continent? I
believe the explanation is not difficult, and that it is perhaps
applicable to nearly analogous facts observed in other quarters of the
world. Considering the enormous power of denudation which the sea
possesses, as shown by numberless facts, it is not probable that a
sedimentary deposit, when being upraised, could pass through the ordeal
of the beach, so as to be preserved in sufficient masses to last to a
distant period, without it were originally of wide extent and of
considerable thickness: now it is impossible on a moderately shallow
bottom, which alone is favourable to most living creatures, that a
thick and widely extended covering of sediment could be spread out,
without the bottom sank down to receive the successive layers. This
seems to have actually taken place at about the same period in southern
Patagonia and Chile, though these places are a thousand miles apart.
Hence, if prolonged movements of approximately contemporaneous
subsidence are generally widely extensive, as I am strongly inclined to
believe from my examination of the Coral Reefs of the great oceans—or
if, confining our view to South America, the subsiding movements have
been coextensive with those of elevation, by which, within the same
period of existing shells, the shores of Peru, Chile, Tierra del Fuego,
Patagonia, and La Plata have been upraised—then we can see that at the
same time, at far distant points, circumstances would have been
favourable to the formation of fossiliferous deposits, of wide extent
and of considerable thickness; and such deposits, consequently, would
have a good chance of resisting the wear and tear of successive
beach-lines, and of lasting to a future epoch.
_May_ 21_st._—I set out in company with Don Jose Edwards to the
silver-mine of Arqueros, and thence up the valley of Coquimbo. Passing
through a mountainous country, we reached by nightfall the mines
belonging to Mr. Edwards. I enjoyed my night’s rest here from a reason
which will not be fully appreciated in England, namely, the absence of
fleas! The rooms in Coquimbo swarm with them; but they will not
live here at the height of only three or four thousand feet: it can
scarcely be the trifling diminution of temperature, but some other
cause which destroys these troublesome insects at this place. The mines
are now in a bad state, though they formerly yielded about 2000 pounds
in weight of silver a year. It has been said that “a person with a
copper-mine will gain; with silver he may gain; but with gold he is
sure to lose.” This is not true: all the large Chilian fortunes have
been made by mines of the more precious metals. A short time since an
English physician returned to England from Copiapó, taking with him the
profits of one share in a silver-mine, which amounted to about 24,000
pounds sterling. No doubt a copper-mine with care is a sure game,
whereas the other is gambling, or rather taking a ticket in a lottery.
The owners lose great quantities of rich ores; for no precautions can
prevent robberies. I heard of a gentleman laying a bet with another,
that one of his men should rob him before his face. The ore when
brought out of the mine is broken into pieces, and the useless stone
thrown on one side. A couple of the miners who were thus employed,
pitched, as if by accident, two fragments away at the same moment, and
then cried out for a joke “Let us see which rolls furthest.” The owner,
who was standing by, bet a cigar with his friend on the race. The miner
by this means watched the very point amongst the rubbish where the
stone lay. In the evening he picked it up and carried it to his master,
showing him a rich mass of silver-ore, and saying, “This was the stone
on which you won a cigar by its rolling so far.”
_May_ 23_rd._—We descended into the fertile valley of Coquimbo, and
followed it till we reached an Hacienda belonging to a relation of Don
Jose, where we stayed the next day. I then rode one day’s journey
farther, to see what were declared to be some petrified shells and
beans, which latter turned out to be small quartz pebbles. We passed
through several small villages; and the valley was beautifully
cultivated, and the whole scenery very grand. We were here near the
main Cordillera, and the surrounding hills were lofty. In all parts of
Northern Chile fruit trees produce much more abundantly at a
considerable height near the Andes than in the lower country. The figs
and grapes of this district are
famous for their excellence, and are cultivated to a great extent. This
valley is, perhaps, the most productive one north of Quillota. I
believe it contains, including Coquimbo, 25,000 inhabitants. The next
day I returned to the Hacienda, and thence, together with Don Jose, to
Coquimbo.
_June_ 2_nd._—We set out for the valley of Guasco, following the
coast-road, which was considered rather less desert than the other. Our
first day’s ride was to a solitary house, called Yerba Buena, where
there was pasture for our horses. The shower mentioned as having fallen
a fortnight ago, only reached about half-way to Guasco; we had,
therefore, in the first part of our journey a most faint tinge of
green, which soon faded quite away. Even where brightest, it was
scarcely sufficient to remind one of the fresh turf and budding flowers
of the spring of other countries. While travelling through these
deserts one feels like a prisoner shut up in a gloomy court, who longs
to see something green and to smell a moist atmosphere.
_June_ 3_rd._—Yerba Buena to Carizal. During the first part of the day
we crossed a mountainous rocky desert, and afterwards a long deep sandy
plain, strewed with broken sea-shells. There was very little water, and
that little saline: the whole country, from the coast to the
Cordillera, is an uninhabited desert. I saw traces only of one living
animal in abundance, namely, the shells of a Bulimus, which were
collected together in extraordinary numbers on the driest spots. In the
spring one humble little plant sends out a few leaves, and on these the
snails feed. As they are seen only very early in the morning, when the
ground is slightly damp with dew, the Guasos believe that they are bred
from it. I have observed in other places that extremely dry and sterile
districts, where the soil is calcareous, are extraordinarily favourable
to land-shells. At Carizal there were a few cottages, some brackish
water, and a trace of cultivation: but it was with difficulty that we
purchased a little corn and straw for our horses.
4_th._—Carizal to Sauce. We continued to ride over desert plains,
tenanted by large herds of guanaco. We crossed also the valley of
Chañeral; which, although the most fertile one between Guasco and
Coquimbo, is very narrow, and produces so little pasture that we could
not purchase any for our horses. At Sauce we found a very civil old
gentleman, superintending
a copper-smelting furnace. As an especial favour, he allowed me to
purchase at a high price an armful of dirty straw, which was all the
poor horses had for supper after their long day’s journey. Few
smelting-furnaces are now at work in any part of Chile; it is found
more profitable, on account of the extreme scarcity of firewood, and
from the Chilian method of reduction being so unskilful, to ship the
ore for Swansea. The next day we crossed some mountains to Freyrina, in
the valley of Guasco. During each day’s ride farther northward, the
vegetation became more and more scanty; even the great chandelier-like
cactus was here replaced by a different and much smaller species.
During the winter months, both in Northern Chile and in Peru, a uniform
bank of clouds hangs, at no great height, over the Pacific. From the
mountains we had a very striking view of this white and brilliant
aërial field, which sent arms up the valleys, leaving islands and
promontories in the same manner as the sea does in the Chonos
archipelago and in Tierra del Fuego.
We stayed two days at Freyrina. In the valley of Guasco there are four
small towns. At the mouth there is the port, a spot entirely desert,
and without any water in the immediate neighbourhood. Five leagues
higher up stands Freyrina, a long straggling village, with decent
whitewashed houses. Again, ten leagues further up Ballenar is situated,
and above this Guasco Alto, a horticultural village, famous for its
dried fruit. On a clear day the view up the valley is very fine; the
straight opening terminates in the far-distant snowy Cordillera; on
each side an infinity of crossing lines are blended together in a
beautiful haze. The foreground is singular from the number of parallel
and step-formed terraces; and the included strip of green valley, with
its willow-bushes, is contrasted on both hands with the naked hills.
That the surrounding country was most barren will be readily believed,
when it is known that a shower of rain had not fallen during the last
thirteen months. The inhabitants heard with the greatest envy of the
rain at Coquimbo; from the appearance of the sky they had hopes of
equally good fortune, which, a fortnight afterwards, were realised. I
was at Copiapó at the time; and there the people, with equal envy,
talked of the abundant rain at Guasco. After two or three very dry
years, perhaps with not more than one shower during the
whole time, a rainy year generally follows; and this does more harm
than even the drought. The rivers swell, and cover with gravel and sand
the narrow strips of ground which alone are fit for cultivation. The
floods also injure the irrigating ditches. Great devastation had thus
been caused three years ago.
_June_ 8_th._—We rode on to Ballenar, which takes its name from
Ballenagh in Ireland, the birthplace of the family of O’Higgins, who,
under the Spanish government, were presidents and generals in Chile. As
the rocky mountains on each hand were concealed by clouds, the
terrace-like plains gave to the valley an appearance like that of Santa
Cruz in Patagonia. After spending one day at Ballenar I set out, on the
10th, for the upper part of the valley of Copiapó. We rode all day over
an uninteresting country. I am tired of repeating the epithets barren
and sterile. These words, however, as commonly used, are comparative; I
have always applied them to the plains of Patagonia, which can boast of
spiny bushes and some tufts of grass; and this is absolute fertility,
as compared with Northern Chile. Here again, there are not many spaces
of two hundred yards square, where some little bush, cactus or lichen,
may not be discovered by careful examination; and in the soil seeds lie
dormant ready to spring up during the first rainy winter. In Peru real
deserts occur over wide tracts of country. In the evening we arrived at
a valley in which the bed of the streamlet was damp: following it up,
we came to tolerably good water. During the night the stream, from not
being evaporated and absorbed so quickly, flows a league lower down
than during the day. Sticks were plentiful for firewood, so that it was
a good place of bivouac for us; but for the poor animals there was not
a mouthful to eat.
_June_ 11_th._—We rode without stopping for twelve hours till we
reached an old smelting-furnace, where there was water and firewood;
but our horses again had nothing to eat, being shut up in an old
courtyard. The line of road was hilly, and the distant views
interesting from the varied colours of the bare mountains. It was
almost a pity to see the sun shining constantly over so useless a
country; such splendid weather ought to have brightened fields and
pretty gardens. The next day we reached the valley of Copiapó. I was
heartily glad of it; for the whole journey was a continued source of
anxiety;
it was most disagreeable to hear, whilst eating our own suppers, our
horses gnawing the posts to which they were tied, and to have no means
of relieving their hunger. To all appearance, however, the animals were
quite fresh; and no one could have told that they had eaten nothing for
the last fifty-five hours.
I had a letter of introduction to Mr. Bingley, who received me very
kindly at the Hacienda of Potrero Seco. This estate is between twenty
and thirty miles long, but very narrow, being generally only two fields
wide, one on each side the river. In some parts the estate is of no
width, that is to say, the land cannot be irrigated, and therefore is
valueless, like the surrounding rocky desert. The small quantity of
cultivated land in the whole line of valley does not so much depend on
inequalities of level, and consequent unfitness for irrigation, as on
the small supply of water. The river this year was remarkably full:
here, high up the valley, it reached to the horse’s belly, and was
about fifteen yards wide, and rapid; lower down it becomes smaller and
smaller, and is generally quite lost, as happened during one period of
thirty years, so that not a drop entered the sea. The inhabitants watch
a storm over the Cordillera with great interest; as one good fall of
snow provides them with water for the ensuing year. This is of
infinitely more consequence than rain in the lower country. Rain, as
often as it falls, which is about once in every two or three years, is
a great advantage, because the cattle and mules can for some time
afterwards find a little pasture in the mountains. But without snow on
the Andes, desolation extends throughout the valley. It is on record
that three times nearly all the inhabitants have been obliged to
emigrate to the south. This year there was plenty of water, and every
man irrigated his ground as much as he chose; but it has frequently
been necessary to post soldiers at the sluices, to see that each estate
took only its proper allowance during so many hours in the week. The
valley is said to contain 12,000 souls, but its produce is sufficient
only for three months in the year; the rest of the supply being drawn
from Valparaiso and the south. Before the discovery of the famous
silver-mines of Chanuncillo, Copiapó was in a rapid state of decay; but
now it is in a very thriving condition; and the town, which was
completely overthrown by an earthquake, has been rebuilt.
The valley of Copiapó, forming a mere ribbon of green in a desert, runs
in a very southerly direction; so that it is of considerable length to
its source in the Cordillera. The valleys of Guasco and Copiapó may
both be considered as long narrow islands, separated from the rest of
Chile by deserts of rock instead of by salt water. Northward of these,
there is one other very miserable valley, called Paposo, which contains
about two hundred souls; and then there extends the real desert of
Atacama—a barrier far worse than the most turbulent ocean. After
staying a few days at Potrero Seco, I proceeded up the valley to the
house of Don Benito Cruz, to whom I had a letter of introduction. I
found him most hospitable; indeed it is impossible to bear too strong
testimony to the kindness with which travellers are received in almost
every part of South America. The next day I hired some mules to take me
by the ravine of Jolquera into the central Cordillera. On the second
night the weather seemed to foretell a storm of snow or rain, and
whilst lying in our beds we felt a trifling shock of an earthquake.
The connexion between earthquakes and the weather has been often
disputed: it appears to me to be a point of great interest, which is
little understood. Humboldt has remarked in one part of the _ Personal
Narrative,_[1] that it would be difficult for any person who had long
resided in New Andalusia, or in Lower Peru, to deny that there exists
some connection between these phenomena: in another part, however, he
seems to think the connexion fanciful. At Guayaquil it is said that a
heavy shower in the dry season is invariably followed by an earthquake.
In Northern Chile, from the extreme infrequency of rain, or even of
weather foreboding rain, the probability of accidental coincidences
becomes very small; yet the inhabitants are here most firmly convinced
of some connexion between the state of the atmosphere and of the
trembling of the ground: I was much struck by this when mentioning to
some people at Copiapó that there had been a sharp shock at Coquimbo:
they
immediately cried out, “How fortunate! there will be plenty of pasture
there this year.” To their minds an earthquake foretold rain as surely
as rain foretold abundant pasture. Certainly it did so happen that on
the very day of the earthquake that shower of rain fell which I have
described as in ten days’ time producing a thin sprinkling of grass. At
other times rain has followed earthquakes at a period of the year when
it is a far greater prodigy than the earthquake itself: this happened
after the shock of November 1822, and again in 1829 at Valparaiso; also
after that of September 1833, at Tacna. A person must be somewhat
habituated to the climate of these countries to perceive the extreme
improbability of rain falling at such seasons, except as a consequence
of some law quite unconnected with the ordinary course of the weather.
In the cases of great volcanic eruptions, as that of Coseguina, where
torrents of rain fell at a time of the year most unusual for it, and
“almost unprecedented in Central America,” it is not difficult to
understand that the volumes of vapour and clouds of ashes might have
disturbed the atmospheric equilibrium. Humboldt extends this view to
the case of earthquakes unaccompanied by eruptions; but I can hardly
conceive it possible that the small quantity of aëriform fluids which
then escape from the fissured ground can produce such remarkable
effects. There appears much probability in the view first proposed by
Mr. P. Scrope, that when the barometer is low, and when rain might
naturally be expected to fall, the diminished pressure of the
atmosphere over a wide extent of country might well determine the
precise day on which the earth, already stretched to the utmost by the
subterranean forces, should yield, crack, and consequently tremble. It
is, however, doubtful how far this idea will explain the circumstance
of torrents of rain falling in the dry season during several days,
after an earthquake unaccompanied by an eruption; such cases seem to
bespeak some more intimate connexion between the atmospheric and
subterranean regions.

Hamilton see _Trans. of British Association,_ 1840. For those on
Coseguina see Mr. Caldcleugh in _Phil. Trans._ 1835. In the former
edition I collected several references on the coincidences between
sudden falls in the barometer and earthquakes; and between earthquakes
and meteors.
Finding little of interest in this part of the ravine, we retraced our
steps to the house of Don Benito, where I stayed two days collecting
fossil shells and wood. Great prostrate silicified trunks of trees,
embedded in a conglomerate, were
extraordinarily numerous. I measured one which was fifteen feet in
circumference: how surprising it is that every atom of the woody matter
in this great cylinder should have been removed and replaced by silex
so perfectly that each vessel and pore is preserved! These trees
flourished at about the period of our lower chalk; they all belonged to
the fir-tribe. It was amusing to hear the inhabitants discussing the
nature of the fossil shells which I collected, almost in the same terms
as were used a century ago in Europe,—namely, whether or not they had
been thus “born by nature.” My geological examination of the country
generally created a good deal of surprise amongst the Chilenos: it was
long before they could be convinced that I was not hunting for mines.
This was sometimes troublesome: I found the most ready way of
explaining my employment was to ask them how it was that they
themselves were not curious concerning earthquakes and volcanos?—why
some springs were hot and others cold?—why there were mountains in
Chile, and not a hill in La Plata? These bare questions at once
satisfied and silenced the greater number; some, however (like a few in
England who are a century behindhand), thought that all such inquiries
were useless and impious; and that it was quite sufficient that God had
thus made the mountains.
An order had recently been issued that all stray dogs should be killed,
and we saw many lying dead on the road. A great number had lately gone
mad, and several men had been bitten and had died in consequence. On
several occasions hydrophobia has prevailed in this valley. It is
remarkable thus to find so strange and dreadful a disease appearing
time after time in the same isolated spot. It has been remarked that
certain villages in England are in like manner much more subject to
this visitation than others. Dr. Unanùe states that hydrophobia was
first known in South America in 1803: this statement is corroborated by
Azara and Ulloa having never heard of it in their time. Dr. Unanùe says
that it broke out in Central America, and slowly travelled southward.
It reached Arequipa in 1807; and it is said that some men there, who
had not been bitten, were affected, as were some negroes, who had eaten
a bullock which had died of hydrophobia. At Ica forty-two people thus
miserably perished.
The disease came on between twelve and ninety days after the bite; and
in those cases where it did come on, death ensued invariably within
five days. After 1808 a long interval ensued without any cases. On
inquiry, I did not hear of hydrophobia in Van Diemen’s Land, or in
Australia; and Burchell says that during the five years he was at the
Cape of Good Hope, he never heard of an instance of it. Webster asserts
that at the Azores hydrophobia has never occurred; and the same
assertion has been made with respect to Mauritius and St. Helena.[2] In
so strange a disease some information might possibly be gained by
considering the circumstances under which it originates in distant
climates; for it is improbable that a dog already bitten should have
been brought to these distant countries.

At night a stranger arrived at the house of Don Benito and asked
permission to sleep there. He said he had been wandering about the
mountains for seventeen days, having lost his way. He started from
Guasco, and being accustomed to travelling in the Cordillera, did not
expect any difficulty in following the track to Copiapó; but he soon
became involved in a labyrinth of mountains whence he could not escape.
Some of his mules had fallen over precipices and he had been in great
distress. His chief difficulty arose from not knowing where to find
water in the lower country, so that he was obliged to keep bordering
the central ranges.
We returned down the valley, and on the 22nd reached the town of
Copiapó. The lower part of the valley is broad, forming a fine plain
like that of Quillota. The town covers a considerable space of ground,
each house possessing a garden: but it is an uncomfortable place, and
the dwellings are poorly furnished. Every one seems bent on the one
object of making money, and then migrating as quickly as possible. All
the inhabitants are more or less directly concerned with mines; and
mines and ores are the sole subjects of conversation. Necessaries of
all sorts are extremely dear; as the distance from the town to the port
is eighteen leagues, and the land
carriage very expensive. A fowl costs five or six shillings; meat is
nearly as dear as in England; firewood, or rather sticks, are brought
on donkeys from a distance of two and three days’ journey within the
Cordillera; and pasturage for animals is a shilling a day: all this for
South America is wonderfully exorbitant.
_June_ 26_th._—I hired a guide and eight mules to take me into the
Cordillera by a different line from my last excursion. As the country
was utterly desert, we took a cargo and a half of barley mixed with
chopped straw. About two leagues above the town a broad valley called
the “Despoblado,” or uninhabited, branches off from that one by which
we had arrived. Although a valley of the grandest dimensions, and
leading to a pass across the Cordillera, yet it is completely dry,
excepting perhaps for a few days during some very rainy winter. The
sides of the crumbling mountains were furrowed by scarcely any ravines;
and the bottom of the main valley, filled with shingle, was smooth and
nearly level. No considerable torrent could ever have flowed down this
bed of shingle; for if it had, a great cliff-bounded channel, as in all
the southern valleys, would assuredly have been formed. I feel little
doubt that this valley, as well as those mentioned by travellers in
Peru, were left in the state we now see them by the waves of the sea,
as the land slowly rose. I observed in one place where the Despoblado
was joined by a ravine (which in almost any other chain would have been
called a grand valley), that its bed, though composed merely of sand
and gravel, was higher than that of its tributary. A mere rivulet of
water, in the course of an hour, would have cut a channel for itself;
but it was evident that ages had passed away, and no such rivulet had
drained this great tributary. It was curious to behold the machinery,
if such a term may be used, for the drainage, all, with the last
trifling exception, perfect, yet without any signs of action. Every one
must have remarked how mud-banks, left by the retiring tide, imitate in
miniature a country with hill and dale; and here we have the original
model in rock, formed as the continent rose during the secular
retirement of the ocean, instead of during the ebbing and flowing of
the tides. If a shower of rain falls on the
mud-bank, when left dry, it deepens the already-formed shallow lines of
excavation; and so it is with the rain of successive centuries on the
bank of rock and soil, which we call a continent.
We rode on after it was dark, till we reached a side ravine with a
small well, called “Agua amarga.” The water deserved its name, for
besides being saline it was most offensively putrid and bitter; so that
we could not force ourselves to drink either tea or maté. I suppose the
distance from the river of Copiapó to this spot was at least
twenty-five or thirty English miles; in the whole space there was not a
single drop of water, the country deserving the name of desert in the
strictest sense. Yet about half-way we passed some old Indian ruins
near Punta Gorda: I noticed also in front of some of the valleys which
branch off from the Despoblado, two piles of stones placed a little way
apart, and directed so as to point up the mouths of these small
valleys. My companions knew nothing about them, and only answered my
queries by their imperturbable “quien sabe?”
I observed Indian ruins in several parts of the Cordillera: the most
perfect which I saw were the Ruinas de Tambillos in the Uspallata Pass.
Small square rooms were there huddled together in separate groups: some
of the doorways were yet standing; they were formed by a cross slab of
stone only about three feet high. Ulloa has remarked on the lowness of
the doors in the ancient Peruvian dwellings. These houses, when
perfect, must have been capable of containing a considerable number of
persons. Tradition says that they were used as halting-places for the
Incas, when they crossed the mountains. Traces of Indian habitations
have been discovered in many other parts, where it does not appear
probable that they were used as mere resting-places, but yet where the
land is as utterly unfit for any kind of cultivation as it is near the
Tambillos or at the Incas Bridge, or in the Portillo Pass, at all which
places I saw ruins. In the ravine of Jajuel, near Aconcagua, where
there is no pass, I heard of remains of houses situated at a great
height, where it is extremely cold and sterile. At first I imagined
that these buildings had been places of refuge, built by the Indians on
the first arrival of the Spaniards; but I have since been inclined to
speculate on the probability of a small change of climate.
In this northern part of Chile, within the Cordillera, old Indian
houses are said to be especially numerous: by digging amongst the
ruins, bits of woollen articles, instruments of precious metals, and
heads of Indian corn, are not unfrequently discovered: an arrow-head
made of agate, and of precisely the same form with those now used in
Tierra del Fuego, was given me. I am aware that the Peruvian Indians
now frequently inhabit most lofty and bleak situations; but at Copiapó
I was assured by men who had spent their lives in travelling through
the Andes, that there were very many (_muchisimas_) buildings at
heights so great as almost to border on the perpetual snow, and in
parts where there exist no passes, and where the land produces
absolutely nothing, and what is still more extraordinary, where there
is no water. Nevertheless it is the opinion of the people of the
country (although they are much puzzled by the circumstance), that,
from the appearance of the houses, the Indians must have used them as
places of residence. In this valley, at Punta Gorda, the remains
consisted of seven or eight square little rooms, which were of a
similar form with those at Tambillos, but built chiefly of mud, which
the present inhabitants cannot, either here or, according to Ulloa, in
Peru, imitate in durability. They were situated in the most conspicuous
and defenceless position, at the bottom of the flat broad valley. There
was no water nearer than three or four leagues, and that only in very
small quantity, and bad: the soil was absolutely sterile; I looked in
vain even for a lichen adhering to the rocks. At the present day, with
the advantage of beasts of burden, a mine, unless it were very rich,
could scarcely be worked here with profit. Yet the Indians formerly
chose it as a place of residence! If at the present time two or three
showers of rain were to fall annually, instead of one, as now is the
case, during as many years, a small rill of water would probably be
formed in this great valley; and then, by irrigation (which was
formerly so well understood by the Indians), the soil would easily be
rendered sufficiently productive to support a few families.
I have convincing proofs that this part of the continent of South
America has been elevated near the coast at least from 400 to 500, and
in some parts from 1000 to 1300 feet, since the epoch of existing
shells; and farther inland the rise possibly
may have been greater. As the peculiarly arid character of the climate
is evidently a consequence of the height of the Cordillera, we may feel
almost sure that before the later elevations, the atmosphere could not
have been so completely drained of its moisture as it now is; and as
the rise has been gradual, so would have been the change in climate. On
this notion of a change of climate since the buildings were inhabited,
the ruins must be of extreme antiquity, but I do not think their
preservation under the Chilian climate any great difficulty. We must
also admit on this notion (and this perhaps is a greater difficulty)
that man has inhabited South America for an immensely long period,
inasmuch as any change of climate effected by the elevation of the land
must have been extremely gradual. At Valparaiso, within the last 220
years, the rise has been somewhat less than 19 feet: at Lima a
sea-beach has certainly been upheaved from 80 to 90 feet, within the
Indio-human period: but such small elevations could have had little
power in deflecting the moisture-bringing atmospheric currents. Dr.
Lund, however, found human skeletons in the caves of Brazil, the
appearance of which induced him to believe that the Indian race has
existed during a vast lapse of time in South America.
When at Lima, I conversed on these subjects[3] with Mr. Gill, a civil
engineer, who had seen much of the interior country. He told me that a
conjecture of a change of climate had sometimes crossed his mind; but
that he thought that the greater portion of land, now incapable of
cultivation, but covered with Indian ruins, had been reduced to this
state by the water-conduits, which the Indians formerly constructed on
so wonderful a scale, having been injured by neglect and by
subterranean movements. I may here mention that the Peruvians actually
carried their irrigating streams in tunnels through hills of solid
rock. Mr. Gill told me he had been employed professionally to examine
one: he found the passage low, narrow, crooked, and not of uniform
breadth, but of very considerable length. Is it not most wonderful that
men should
have attempted such operations, without the use of iron or gunpowder?
Mr. Gill also mentioned to me a most interesting, and, as far as I am
aware, quite unparalleled case, of a subterranean disturbance having
changed the drainage of a country. Travelling from Casma to Huaraz (not
very far distant from Lima), he found a plain covered with ruins and
marks of ancient cultivation but now quite barren. Near it was the dry
course of a considerable river, whence the water for irrigation had
formerly been conducted. There was nothing in the appearance of the
watercourse to indicate that the river had not flowed there a few years
previously; in some parts, beds of sand and gravel were spread out; in
others, the solid rock had been worn into a broad channel, which in one
spot was about 40 yards in breadth and 8 feet deep. It is self-evident
that a person following up the course of a stream will always ascend at
a greater or less inclination: Mr. Gill, therefore, was much
astonished, when walking up the bed of this ancient river, to find
himself suddenly going down hill. He imagined that the downward slope
had a fall of about 40 or 50 feet perpendicular. We here have
unequivocal evidence that a ridge had been uplifted right across the
old bed of a stream. From the moment the river-course was thus arched,
the water must necessarily have been thrown back, and a new channel
formed. From that moment, also, the neighbouring plain must have lost
its fertilising stream, and become a desert.
[3] Temple, in his travels through Upper Peru, or Bolivia, in going
from Potosi to Oruro, says “I saw many Indian villages or dwellings in
ruins, up even to the very tops of the mountains, attesting a former
population where now all is desolate.” He makes similar remarks in
another place; but I cannot tell whether this desolation has been
caused by a want of population, or by an altered condition of the
land.
_June_ 27_th._—We set out early in the morning, and by mid-day reached
the ravine of Paypote, where there is a tiny rill of water, with a
little vegetation, and even a few algarroba trees, a kind of mimosa.
From having firewood, a smelting-furnace had formerly been built here:
we found a solitary man in charge of it, whose sole employment was
hunting guanacos. At night it froze sharply; but having plenty of wood
for our fire, we kept ourselves warm.
_June_ 28_th._—We continued gradually ascending, and the valley now
changed into a ravine. During the day we saw several guanacos, and the
track of the closely-allied species, the Vicuña: this latter animal is
pre-eminently alpine in its habits; it seldom descends much below the
limit of perpetual snow, and therefore haunts even a more lofty and
sterile situation than the guanaco.
The only other animal which we saw in any number was a small fox: I
suppose this animal preys on the mice and other small rodents which, as
long as there is the least vegetation, subsist in considerable numbers
in very desert places. In Patagonia, even on the borders of the
salinas, where a drop of fresh water can never be found, excepting dew,
these little animals swarm. Next to lizards, mice appear to be able to
support existence on the smallest and driest portions of the earth—even
on islets in the midst of great oceans.
The scene on all sides showed desolation, brightened and made palpable
by a clear, unclouded sky. For a time such scenery is sublime, but this
feeling cannot last, and then it becomes uninteresting. We bivouacked
at the foot of the “primera linea,” or the first line of the partition
of the waters. The streams, however, on the east side do not flow to
the Atlantic, but into an elevated district, in the middle of which
there is a large salina, or salt lake;—thus forming a little Caspian
Sea at the height, perhaps, of ten thousand feet. Where we slept, there
were some considerable patches of snow, but they do not remain
throughout the year. The winds in these lofty regions obey very regular
laws; every day a fresh breeze blows up the valley, and at night, an
hour or two after sunset, the air from the cold regions above descends
as through a funnel. This night it blew a gale of wind, and the
temperature must have been considerably below the freezing-point, for
water in a vessel soon became a block of ice. No clothes seemed to
oppose any obstacle to the air; I suffered very much from the cold, so
that I could not sleep, and in the morning rose with my body quite dull
and benumbed.
In the Cordillera farther southward people lose their lives from
snow-storms; here, it sometimes happens from another cause. My guide,
when a boy of fourteen years old, was passing the Cordillera with a
party in the month of May; and while in the central parts, a furious
gale of wind arose, so that the men could hardly cling on their mules,
and stones were flying along the ground. The day was cloudless, and not
a speck of snow fell, but the temperature was low. It is probable that
the thermometer would not have stood very many degrees below the
freezing-point, but the effect on their bodies, ill protected by
clothing, must have been in proportion to the rapidity of the current
of cold air. The gale lasted for more than a day; the
men began to lose their strength, and the mules would not move onwards.
My guide’s brother tried to return, but he perished, and his body was
found two years afterwards, lying by the side of his mule near the
road, with the bridle still in his hand. Two other men in the party
lost their fingers and toes; and out of two hundred mules and thirty
cows, only fourteen mules escaped alive. Many years ago the whole of a
large party are supposed to have perished from a similar cause, but
their bodies to this day have never been discovered. The union of a
cloudless sky, low temperature, and a furious gale of wind, must be, I
should think, in all parts of the world an unusual occurrence.
_June_ 29_th._—We gladly travelled down the valley to our former
night’s lodging, and thence to near the Agua amarga. On July 1st we
reached the valley of Copiapó. The smell of the fresh clover was quite
delightful, after the scentless air of the dry sterile Despoblado.
Whilst staying in the town I heard an account from several of the
inhabitants, of a hill in the neighbourhood which they called “El
Bramador,”—the roarer or bellower. I did not at the time pay sufficient
attention to the account; but, as far as I understood, the hill was
covered by sand, and the noise was produced only when people, by
ascending it, put the sand in motion. The same circumstances are
described in detail on the authority of Seetzen and Ehrenberg,[4] as
the cause of the sounds which have been heard by many travellers on
Mount Sinai near the Red Sea. One person with whom I conversed had
himself heard the noise: he described it as very surprising; and he
distinctly stated that, although he could not understand how it was
caused, yet it was necessary to set the sand rolling down the
acclivity. A horse walking over dry and coarse sand causes a peculiar
chirping noise from the friction of the particles; a circumstance which
I several times noticed on the coast of Brazil.

Three days afterwards I heard of the _Beagle’s_ arrival at the Port,
distant eighteen leagues from the town. There is very little land
cultivated down the valley; its wide expanse supports a wretched wiry
grass, which even the donkeys can hardly eat.
This poorness of the vegetation is owing to the quantity of saline
matter with which the soil is impregnated. The Port consists of an
assemblage of miserable little hovels, situated at the foot of a
sterile plain. At present, as the river contains water enough to reach
the sea, the inhabitants enjoy the advantage of having fresh water
within a mile and a half. On the beach there were large piles of
merchandise, and the little place had an air of activity. In the
evening I gave my adios, with a hearty good-will, to my companion
Mariano Gonzales, with whom I had ridden so many leagues in Chile. The
next morning the _Beagle_ sailed for Iquique.
_July_ 12_th._—We anchored in the port of Iquique, in latitude 20° 12′,
on the coast of Peru. The town contains about a thousand inhabitants,
and stands on a little plain of sand at the foot of a great wall of
rock, 2000 feet in height, here forming the coast. The whole is utterly
desert. A light shower of rain falls only once in very many years; and
the ravines consequently are filled with detritus, and the
mountainsides covered by piles of fine white sand, even to a height of
a thousand feet. During this season of the year a heavy bank of clouds,
stretched over the ocean, seldom rises above the wall of rocks on the
coast. The aspect of the place was most gloomy; the little port, with
its few vessels, and small group of wretched houses, seemed overwhelmed
and out of all proportion with the rest of the scene.
The inhabitants live like persons on board a ship: every necessary
comes from a distance: water is brought in boats from Pisagua, about
forty miles northward, and is sold at the rate of nine reals (4s. 6d.)
an eighteen-gallon cask: I bought a wine-bottle full for threepence. In
like manner firewood, and of course every article of food, is imported.
Very few animals can be maintained in such a place: on the ensuing
morning I hired with difficulty, at the price of four pounds sterling,
two mules and a guide to take me to the nitrate of soda works. These
are at present the support of Iquique. This salt was first exported in
1830: in one year an amount in value of one hundred thousand pounds
sterling was sent to France and England. It is principally used as a
manure and in the manufacture of nitric acid: owing to its deliquescent
property
it will not serve for gunpowder. Formerly there were two exceedingly
rich silver-mines in this neighbourhood, but their produce is now very
small.
Our arrival in the offing caused some little apprehension. Peru was in
a state of anarchy; and each party having demanded a contribution, the
poor town of Iquique was in tribulation, thinking the evil hour was
come. The people had also their domestic troubles; a short time before,
three French carpenters had broken open, during the same night, the two
churches, and stolen all the plate: one of the robbers, however,
subsequently confessed, and the plate was recovered. The convicts were
sent to Arequipa, which, though the capital of this province, is two
hundred leagues distant; the government there thought it a pity to
punish such useful workmen who could make all sorts of furniture; and
accordingly liberated them. Things being in this state, the churches
were again broken open, but this time the plate was not recovered. The
inhabitants became dreadfully enraged, and declaring that none but
heretics would thus “eat God Almighty,” proceeded to torture some
Englishmen, with the intention of afterwards shooting them. At last the
authorities interfered, and peace was established.
13_th._—In the morning I started for the saltpetre-works, a distance of
fourteen leagues. Having ascended the steep coast-mountains by a zigzag
sandy track, we soon came in view of the mines of Guantajaya and St.
Rosa. These two small villages are placed at the very mouths of the
mines; and being perched up on hills, they had a still more unnatural
and desolate appearance than the town of Iquique. We did not reach the
saltpetre works till after sunset, having ridden all day across an
undulating country, a complete and utter desert. The road was strewed
with the bones and dried skins of many beasts of burden which had
perished on it from fatigue. Excepting the Vultur aura, which preys on
the carcasses, I saw neither bird, quadruped, reptile, nor insect. On
the coast-mountains, at the height of about 2000 feet, where during
this season the clouds generally hang, a very few cacti were growing in
the clefts of rock; and the loose sand was strewed over with a lichen,
which lies on the surface quite unattached. This plant belongs to the
genus Cladonia, and somewhat resembles the
reindeer lichen. In some parts it was in sufficient quantity to tinge
the sand, as seen from a distance, of a pale yellowish colour. Farther
inland, during the whole ride of fourteen leagues, I saw only one other
vegetable production, and that was a most minute yellow lichen, growing
on the bones of the dead mules. This was the first true desert which I
had seen: the effect on me was not impressive; but I believe this was
owing to my having become gradually accustomed to such scenes, as I
rode northward from Valparaiso, through Coquimbo, to Copiapó. The
appearance of the country was remarkable, from being covered by a thick
crust of common salt, and of a stratified saliferous alluvium, which
seems to have been deposited as the land slowly rose above the level of
the sea. The salt is white, very hard, and compact: it occurs in
water-worn nodules projecting from the agglutinated sand, and is
associated with much gypsum. The appearance of this superficial mass
very closely resembled that of a country after snow, before the last
dirty patches are thawed. The existence of this crust of a soluble
substance over the whole face of the country shows how extraordinarily
dry the climate must have been for a long period.
At night I slept at the house of the owner of one of the saltpetre
mines. The country is here as unproductive as near the coast; but
water, having rather a bitter and brackish taste, can be procured by
digging wells. The well at this house was thirty-six yards deep: as
scarcely any rain falls, it is evident the water is not thus derived;
indeed if it were, it could not fail to be as salt as brine, for the
whole surrounding country is incrusted with various saline substances.
We must therefore conclude that it percolates under ground from the
Cordillera, though distant many leagues. In that direction there are a
few small villages, where the inhabitants, having more water, are
enabled to irrigate a little land, and raise hay, on which the mules
and asses, employed in carrying the saltpetre, are fed. The nitrate of
soda was now selling at the ship’s side at fourteen shillings per
hundred pounds: the chief expense is its transport to the sea-coast.
The mine consists of a hard stratum, between two and three feet thick,
of the nitrate mingled with a little of the sulphate of soda and a good
deal of common salt. It lies close beneath the surface, and follows for
a length of
one hundred and fifty miles the margin of a grand basin or plain; this,
from its outline, manifestly must once have been a lake, or more
probably an inland arm of the sea, as may be inferred from the presence
of iodic salts in the saline stratum. The surface of the plain is 3300
feet above the Pacific.
19_th._—We anchored in the Bay of Callao, the seaport of Lima, the
capital of Peru. We stayed here six weeks, but from the troubled state
of public affairs I saw very little of the country. During our whole
visit the climate was far from being so delightful as it is generally
represented. A dull heavy bank of clouds constantly hung over the land,
so that during the first sixteen days I had only one view of the
Cordillera behind Lima. These mountains, seen in stages, one above the
other, through openings in the clouds, had a very grand appearance. It
is almost become a proverb, that rain never falls in the lower part of
Peru. Yet this can hardly be considered correct; for during almost
every day of our visit there was a thick drizzling mist, which was
sufficient to make the streets muddy and one’s clothes damp: this the
people are pleased to call Peruvian dew. That much rain does not fall
is very certain, for the houses are covered only with flat roofs made
of hardened mud; and on the mole ship-loads of wheat were piled up,
being thus left for weeks together without any shelter.
I cannot say I liked the very little I saw of Peru: in summer, however,
it is said that the climate is much pleasanter. In all seasons, both
inhabitants and foreigners suffer from severe attacks of ague. This
disease is common on the whole coast of Peru, but is unknown in the
interior. The attacks of illness which arise from miasma never fail to
appear most mysterious. So difficult is it to judge from the aspect of
a country, whether or not it is healthy, that if a person had been told
to choose within the tropics a situation appearing favourable for
health, very probably he would have named this coast. The plain round
the outskirts of Callao is sparingly covered with a coarse grass, and
in some parts there are a few stagnant, though very small, pools of
water. The miasma, in all probability, arises from these: for the town
of Arica was similarly circumstanced, and its healthiness was much
improved
by the drainage of some little pools. Miasma is not always produced by
a luxuriant vegetation with an ardent climate; for many parts of
Brazil, even where there are marshes and a rank vegetation, are much
more healthy than this sterile coast of Peru. The densest forests in a
temperate climate, as in Chiloe, do not seem in the slightest degree to
affect the healthy condition of the atmosphere.
The island of St. Jago, at the Cape de Verds, offers another
strongly-marked instance of a country, which any one would have
expected to find most healthy, being very much the contrary. I have
described the bare and open plains as supporting, during a few weeks
after the rainy season, a thin vegetation, which directly withers away
and dries up: at this period the air appears to become quite poisonous;
both natives and foreigners often being affected with violent fevers.
On the other hand, the Galapagos Archipelago, in the Pacific, with a
similar soil, and periodically subject to the same process of
vegetation, is perfectly healthy. Humboldt has observed that “under the
torrid zone, the smallest marshes are the most dangerous, being
surrounded, as at Vera Cruz and Carthagena, with an arid and sandy
soil, which raises the temperature of the ambient air.”[5] On the coast
of Peru, however, the temperature is not hot to any excessive degree;
and perhaps in consequence the intermittent fevers are not of the most
malignant order. In all unhealthy countries the greatest risk is run by
sleeping on shore. Is this owing to the state of the body during sleep,
or to a greater abundance of miasma at such times? It appears certain
that those who stay on board a vessel, though anchored at only a short
distance from the coast, generally suffer less than those actually on
shore. On the other hand, I have heard of one remarkable case where a
fever broke out among the crew of a man-of-war some hundred miles off
the coast of Africa, and at the same time one of those fearful
periods[6] of death commenced at Sierra Leone.
[5] _Political Essay on the Kingdom of New Spain,_ vol. iv, p. 199.
[6] A similar interesting case is recorded in the _Madras Medical
Quart. Journ._ 1839, p. 340. Dr. Ferguson in his admirable Paper (see
9th vol. of _Edinburgh Royal Trans._), shows clearly that the poison
is generated in the drying process; and hence that dry hot countries
are often the most unhealthy.
No state in South America, since the declaration of
independence, has suffered more from anarchy than Peru. At the time of
our visit there were four chiefs in arms contending for supremacy in
the government: if one succeeded in becoming for a time very powerful,
the others coalesced against him; but no sooner were they victorious
than they were again hostile to each other. The other day, at the
Anniversary of the Independence, high mass was performed, the President
partaking of the sacrament: during the _Te Deum laudamus,_ instead of
each regiment displaying the Peruvian flag, a black one with death’s
head was unfurled. Imagine a government under which such a scene could
be ordered, on such an occasion, to be typical of their determination
of fighting to death! This state of affairs happened at a time very
unfortunately for me, as I was precluded from taking any excursions
much beyond the limits of the town. The barren island of San Lorenzo,
which forms the harbour, was nearly the only place where one could walk
securely. The upper part, which is upwards of 1000 feet in height,
during this season of the year (winter), comes within the lower limit
of the clouds; and in consequence an abundant cryptogamic vegetation
and a few flowers cover the summit. On the hills near Lima, at a height
but little greater, the ground is carpeted with moss, and beds of
beautiful yellow lilies, called Amancaes. This indicates a very much
greater degree of humidity than at a corresponding height at Iquique.
Proceeding northward of Lima, the climate becomes damper, till on the
banks of the Guayaquil, nearly under the equator, we find the most
luxuriant forests. The change, however, from the sterile coast of Peru
to that fertile land is described as taking place rather abruptly in
the latitude of Cape Blanco, two degrees south of Guayaquil.
Callao is a filthy, ill-built, small seaport. The inhabitants, both
here and at Lima, present every imaginable shade of mixture, between
European, Negro, and Indian blood. They appear a depraved, drunken set
of people. The atmosphere is loaded with foul smells, and that peculiar
one, which may be perceived in almost every town within the tropics,
was here very strong. The fortress, which withstood Lord Cochrane’s
long siege, has an imposing appearance. But the President, during our
stay, sold the brass guns, and proceeded to dismantle parts of it. The
reason assigned was, that he had not an
officer to whom he could trust so important a charge. He himself had
good reason for thinking so, as he had obtained the presidentship by
rebelling while in charge of this same fortress. After we left South
America, he paid the penalty in the usual manner, by being conquered,
taken prisoner, and shot.
Lima stands on a plain in a valley, formed during the gradual retreat
of the sea. It is seven miles from Callao, and is elevated 500 feet
above it; but from the slope being very gradual, the road appears
absolutely level; so that when at Lima it is difficult to believe one
has ascended even one hundred feet: Humboldt has remarked on this
singularly deceptive case. Steep barren hills rise like islands from
the plain, which is divided, by straight mud-walls, into large green
fields. In these scarcely a tree grows excepting a few willows, and an
occasional clump of bananas and of oranges. The city of Lima is now in
a wretched state of decay: the streets are nearly unpaved; and heaps of
filth are piled up in all directions, where the black gallinazos, tame
as poultry, pick up bits of carrion. The houses have generally an upper
story, built, on account of the earthquakes, of plastered woodwork; but
some of the old ones, which are now used by several families, are
immensely large, and would rival in suites of apartments the most
magnificent in any place. Lima, the City of the Kings, must formerly
have been a splendid town. The extraordinary number of churches gives
it, even at the present day, a peculiar and striking character,
especially when viewed from a short distance.
One day I went out with some merchants to hunt in the immediate
vicinity of the city. Our sport was very poor; but I had an opportunity
of seeing the ruins of one of the ancient Indian villages, with its
mound like a natural hill in the centre. The remains of houses,
enclosures, irrigating streams, and burial mounds, scattered over this
plain, cannot fail to give one a high idea of the condition and number
of the ancient population. When their earthenware, woollen clothes,
utensils of elegant forms cut out of the hardest rocks, tools of
copper, ornaments of precious stones, palaces, and hydraulic works, are
considered, it is impossible not to respect the considerable advance
made by them in the arts of civilisation. The burial
mounds, called Huacas, are really stupendous; although in some places
they appear to be natural hills encased and modelled.
There is also another and very different class of ruins which possesses
some interest, namely, those of old Callao, overwhelmed by the great
earthquake of 1746, and its accompanying wave. The destruction must
have been more complete even than at Talcahuano. Quantities of shingle
almost conceal the foundations of the walls, and vast masses of
brickwork appear to have been whirled about like pebbles by the
retiring waves. It has been stated that the land subsided during this
memorable shock: I could not discover any proof of this; yet it seems
far from improbable, for the form of the coast must certainly have
undergone some change since the foundation of the old town; as no
people in their senses would willingly have chosen for their building
place the narrow spit of shingle on which the ruins now stand. Since
our voyage, M. Tschudi has come to the conclusion, by the comparison of
old and modern maps, that the coast both north and south of Lima has
certainly subsided.
On the island of San Lorenzo there are very satisfactory proofs of
elevation within the recent period; this of course is not opposed to
the belief of a small sinking of the ground having subsequently taken
place. The side of this island fronting the Bay of Callao is worn into
three obscure terraces, the lower one of which is covered by a bed a
mile in length, almost wholly composed of shells of eighteen species,
now living in the adjoining sea. The height of this bed is eighty-five
feet. Many of the shells are deeply corroded, and have a much older and
more decayed appearance than those at the height of 500 or 600 feet on
the coast of Chile. These shells are associated with much common salt,
a little sulphate of lime (both probably left by the evaporation of the
spray, as the land slowly rose), together with sulphate of soda and
muriate of lime. They rest on fragments of the underlying sandstone,
and are covered by a few inches thick of detritus. The shells higher up
on this terrace could be traced scaling off in flakes, and falling into
an impalpable powder; and on an upper terrace, at the height of 170
feet, and likewise at some considerably higher points, I found a layer
of saline powder of
exactly similar appearance, and lying in the same relative position. I
have no doubt that this upper layer originally existed as a bed of
shells, like that on the eighty-five-feet ledge; but it does not now
contain even a trace of organic structure. The powder has been analysed
for me by Mr. T. Reeks; it consists of sulphates and muriates both of
lime and soda, with very little carbonate of lime. It is known that
common salt and carbonate of lime left in a mass for some time together
partly decompose each other; though this does not happen with small
quantities in solution. As the half-decomposed shells in the lower
parts are associated with much common salt, together with some of the
saline substances composing the upper saline layer, and as these shells
are corroded and decayed in a remarkable manner, I strongly suspect
that this double decomposition has here taken place. The resultant
salts, however, ought to be carbonate of soda and muriate of lime, the
latter is present, but not the carbonate of soda. Hence I am led to
imagine that by some unexplained means the carbonate of soda becomes
changed into the sulphate. It is obvious that the saline layer could
not have been preserved in any country in which abundant rain
occasionally fell: on the other hand this very circumstance, which at
first sight appears so highly favourable to the long preservation of
exposed shells, has probably been the indirect means, through the
common salt not having been washed away, of their decomposition and
early decay.
I was much interested by finding on the terrace, at the height of
eighty-five feet, _embedded_ amidst the shells and much sea-drifted
rubbish, some bits of cotton thread, plaited rush, and the head of a
stalk of Indian corn: I compared these relics with similar ones taken
out of the Huacas, or old Peruvian tombs, and found them identical in
appearance. On the mainland in front of San Lorenzo, near Bellavista,
there is an extensive and level plain about a hundred feet high, of
which the lower part is formed of alternating layers of sand and impure
clay, together with some gravel, and the surface, to the depth of from
three to six feet, of a reddish loam, containing a few scattered
sea-shells and numerous small fragments of coarse red earthenware, more
abundant at certain spots than at others. At first I was inclined to
believe that this superficial
bed, from its wide extent and smoothness, must have been deposited
beneath the sea; but I afterwards found in one spot that it lay on an
artificial floor of round stones. It seems, therefore, most probable
that at a period when the land stood at a lower level there was a plain
very similar to that now surrounding Callao, which, being protected by
a shingle beach, is raised but very little above the level of the sea.
On this plain, with its underlying red-clay beds, I imagine that the
Indians manufactured their earthen vessels; and that, during some
violent earthquake, the sea broke over the beach, and converted the
plain into a temporary lake, as happened round Callao in 1713 and 1746.
The water would then have deposited mud containing fragments of pottery
from the kilns, more abundant at some spots than at others, and shells
from the sea. This bed with fossil earthenware stands at about the same
height with the shells on the lower terrace of San Lorenzo, in which
the cotton-thread and other relics were embedded. Hence we may safely
conclude that within the Indo-human period there has been an elevation,
as before alluded to, of more than eighty-five feet; for some little
elevation must have been lost by the coast having subsided since the
old maps were engraved. At Valparaiso, although in the 220 years before
our visit the elevation cannot have exceeded nineteen feet, yet
subsequently to 1817 there has been a rise, partly insensible and
partly by a start during the shock of 1822, of ten or eleven feet. The
antiquity of the Indo-human race here, judging by the eighty-five feet
rise of the land since the relics were embedded, is the more
remarkable, as on the coast of Patagonia, when the land stood about the
same number of feet lower, the Macrauchenia was a living beast; but as
the Patagonian coast is some way distant from the Cordillera, the
rising there may have been slower than here. At Bahia Blanca the
elevation has been only a few feet since the numerous gigantic
quadrupeds were there entombed; and, according to the generally
received opinion, when these extinct animals were living man did not
exist. But the rising of that part of the coast of Patagonia is perhaps
no way connected with the Cordillera, but rather with a line of old
volcanic rocks in Banda Oriental, so that it may have been infinitely
slower than on the shores of Peru. All these
speculations, however, must be vague; for who will pretend to say that
there may not have been several periods of subsidence, intercalated
between the movements of elevation? for we know that along the whole
coast of Patagonia there have certainly been many and long pauses in
the upward action of the elevatory forces.
