1des. To
the west, they are akin to the comparatively insig-
nificant parallel ranges just noticed, being, if A. at
all, merely A. in miniature. But to the east, the
spurs deserve more consideration. They are two in
number, the one branching off between the 33d and
31st parallels, and the other between the 28th and
24th, The former, called the Sierra de Cordova,
advances like a promontory into the plains of Rio
de La Plata, or Pampas, as they are more gener-
ally denominated, as far as the 65th meridian;
and the latter, called the Sierra de Salta, runs
nearly as far to the east, and in a direction nearly
parallel.
Peruvian Andes.—This part of the chain, stretch-
ing from lat. 24° S. to lat. 6° S.—a distance about
the same as in the last paragraph—is perhaps the
broadest of all the divisions of the A. Tt certainly
contains the largest of the plateaus, the plateau of
Bolivia. Between the 20th and 19th parallels, not
far from the city of Potosi, the chain separates into
two ranges, known as the East and West Cordilleras
of Bolivia; and it is the reunion of these ranges,
between the 15th and 14th parallels, that encloses
the land-locked plateau of Titicaca, containing, as is
said, 30,000 square miles, or an area equal to that of
Ireland. TImmediately above this table-land, the
united ranges in question constitute the mountain-
group of Cuzco, which, in point of superficial extent,
18 stated to be thrice as large as all Switzerland.
About a degree further north, the chain again
separates as before, reuniting also, as before, between
the 11th and 10th parallels, so as to embrace the
cities of Guanta and Guancavelica. Hardly have
the two ranges reunited, when they mass them-
selves into the table-land of Pasco, not quite
half the size of that of Titicaca. Further to
the north, the chain divides, not into two, butb
into three ranges, which unite again, on the
frontiers. of Ecuador, in the group of Loxa, about
lat. 5° 8.
Andes of Ecuador.—Immediately beyond the group
of Loxa, between 4° and 3> of S. lat., the chain
divides into two ranges, which, by again uniting in
2° 27', form the valley of Cuenga; and immediately
beyond this is the group of Assuay, with its table-
land. Then another plateau of no great extent,
and a short stretch of the undivided chain, lead
to the vast table-land of Quito, which is said
to be subdivided by low hills into five smaller
plateaus, two to the east, and three to the west.
Towards the north, the table-land of Quito is suec-
ceeded by the group of Los Pastos, forming the
extreme portion of the A. of Ecuador.
Andes of New Qranada.—Beyond the city of
Almaguer, the chain breaks off into two ranges,
which never again join each other. The range on
the west side remains undivided, till it disappears
near the mouth of the Atrato, a little to the east of
the Isthmus of Darien. But the range on the east,
after massing itself into the group of Paramo de los
Papas, breaks into two branches, which, as dis-
tinguished from the range aforesaid on the west, are
styled the Central and Eastern Cordilleras of New
Granada. These two contain between them the
upper waters of the Magdalena, the eastern separat-
ing them from the basin of the Orinoco, and the
central dividing them from that of the Cauca.
Between them also they contain several considerable
table-lands, the principal one being that of Santa
Fé de Bogota.
Height—Under this head must be treated separ-
ately the plateaus, the most prominent mountains,
and the passes—the altitudes of the lines of perpetual
snow falling more naturally under the head of
Climate. Here, as in the case of breadth, the chain
will be followed from south to north.

These passes will bear a comparison with the
loftiest pinnacles in Europe. The last and lowest
overtops the highest summit of the Pyrenees by
332 feet ; while the last but two, that of Antarangra,
which Herndon traversed, soars 389 feet above Mont
Blanc, the culminating peak of the Alps.
The passes across the A. present a vast variety
of surfaces and levels. They appear to skirt, as often
as practicable, the mountain-torrents; and,awhen
