The Many Islands, With Their Willow-Trees,
And The Flat Headlands, Seen One Behind The Other On The
Northern Boundary Of The Broad Green Valley, Form, By The
Aid Of A Bright Sun, A View Almost Picturesque.
The number
of inhabitants does not exceed a few hundreds.
These Spanish
colonies do not, like our British ones, carry within themselves
the elements of growth. Many Indians of pure blood
reside here: the tribe of the Cacique Lucanee constantly have
their Toldos [2] on the outskirts of the town. The local
government partly supplies them with provisions, by giving them
all the old worn-out horses, and they earn a little by making
horse-rugs and other articles of riding-gear. These Indians
are considered civilized; but what their character may have
gained by a lesser degree of ferocity, is almost counterbalanced
by their entire immorality. Some of the younger men
are, however, improving; they are willing to labour, and a
short time since a party went on a sealing-voyage, and behaved
very well. They were now enjoying the fruits of their
labour, by being dressed in very gay, clean clothes, and by
being very idle. The taste they showed in their dress was
admirable; if you could have turned one of these young
Indians into a statue of bronze, his drapery would have been
perfectly graceful.
One day I rode to a large salt-lake, or Salina, which is
distant fifteen miles from the town. During the winter it
consists of a shallow lake of brine, which in summer is
converted into a field of snow-white salt. The layer near the
margin is from four to five inches thick, but towards the
centre its thickness increases. This lake was two and a half
miles long, and one broad. Others occur in the neighbourhood
many times larger, and with a floor of salt, two and
three feet in thickness, even when under water during the
winter. One of these brilliantly white and level expanses
in the midst of the brown and desolate plain, offers an
extraordinary spectacle. A large quantity of salt is annually
drawn from the salina: and great piles, some hundred
tons in weight, were lying ready for exportation. The season
for working the salinas forms the harvest of Patagones; for
on it the prosperity of the place depends. Nearly the whole
population encamps on the bank of the river, and the people
are employed in drawing out the salt in bullock-waggons,
This salt is crystallized in great cubes, and is remarkably
pure: Mr. Trenham Reeks has kindly analyzed some for me,
and he finds in it only 0.26 of gypsum and 0.22 of earthy
matter. It is a singular fact, that it does not serve so well
for preserving meat as sea-salt from the Cape de Verd
islands; and a merchant at Buenos Ayres told me that he
considered it as fifty per cent. less valuable. Hence the
Cape de Verd salt is constantly imported, and is mixed with
that from these salinas. The purity of the Patagonian salt,
or absence from it of those other saline bodies found in all
sea-water, is the only assignable cause for this inferiority:
a conclusion which no one, I think, would have suspected,
but which is supported by the fact lately ascertained, [3]
that those salts answer best for preserving cheese which
contain most of the deliquescent chlorides.
The border of this lake is formed of mud: and in this
numerous large crystals of gypsum, some of which are three
inches long, lie embedded; whilst on the surface others of
sulphate of soda lie scattered about. The Gauchos call the
former the "Padre del sal," and the latter the "Madre;"
they state that these progenitive salts always occur on the
borders of the salinas, when the water begins to evaporate.
The mud is black, and has a fetid odour. I could not at first
imagine the cause of this, but I afterwards perceived that the
froth which the wind drifted on shore was coloured green,
as if by confervae; I attempted to carry home some of this
green matter, but from an accident failed. Parts of the lake
seen from a short distance appeared of a reddish colour, and
this perhaps was owing to some infusorial animalcula. The
mud in many places was thrown up by numbers of some kind
of worm, or annelidous animal. How surprising it is that
any creatures should be able to exist in brine, and that they
should be crawling among crystals of sulphate of soda and
lime! And what becomes of these worms when, during the
long summer, the surface is hardened into a solid layer of
salt? Flamingoes in considerable numbers inhabit this lake,
and breed here, throughout Patagonia, in Northern Chile,
and at the Galapagos Islands, I met with these birds wherever
there were lakes of brine. I saw them here wading
about in search of food - probably for the worms which burrow
in the mud; and these latter probably feed on infusoria or
confervae. Thus we have a little living world within itself
adapted to these inland lakes of brine. A minute crustaceous
animal (Cancer salinus) is said [4] to live in countless numbers
in the brine-pans at Lymington: but only in those in which
the fluid has attained, from evaporation, considerable
strength - namely, about a quarter of a pound of salt to a
pint of water. Well may we affirm that every part of the
world is habitable! Whether lakes of brine, or those
subterranean ones hidden beneath volcanic mountains - warm
mineral springs - the wide expanse and depths of the ocean
- the upper regions of the atmosphere, and even the surface
of perpetual snow - all support organic beings.
To the northward of the Rio Negro, between it and the
inhabited country near Buenos Ayres, the Spaniards have
only one small settlement, recently established at Bahia
Blanca. The distance in a straight line to Buenos Ayres is
very nearly five hundred British miles.
