Near by stands Antisana in his snowy robe. This volcano ranks next to Chimborazo in dignity. It has a double dome, and an elevation of 19,000 feet. Snow of Dian purity covers it for over 3000 feet; but, judging from the enormous streams of lava on its sides, it must have been a fierce volcano in ages past. The lava streams are worthy of the great mountain from which they flowed. One of them (called "Volcan d'Ansango") is ten miles long and five hundred feet deep, with an average slope of 15°. It is a magnificent sight, as seen from the surrounding paramo—a stream of dark, ragged rocks coming down out of the clouds and snows which cover the summit. The representative products of Antisana are a black, cellular, vitreous trachyte, a fine-grained, tough porphyroid trachyte, and a coarse reddish porphyroid trachyte. An eruption, as late as 1590, is recorded in Johnston's Phys. Atlas. Humboldt saw smoke issuing from several openings in March, 1802.
We ascended this volcano to the height of sixteen thousand feet. On its side is the celebrated hacienda of Antisana, which, more than sixty years ago, sheltered the great Humboldt from the sleet and rain and blast of this lofty region. It was a welcome refuge to us, for we had well nigh perished with cold on the dreary paramo. It is one of the highest human habitations in the world, being thirteen thousand three hundred feet above the sea, or a thousand feet higher than the Peak of Teneriffe.[79] The mean temperature is the same as that of Quebec, so that thirteen thousand feet in elevation at the equator is equal to 47° in latitude.[80] Here is an extensive corral, inclosing thousands of cattle, owned by a rheumatic old gentleman, Señor Valdevieso, who supplies the beef-market of Quito.[81] A desire for beef has alone brought man and his beast to this chilly altitude. It is difficult to get a quart of milk, and impossible to find a pound of butter at this hacienda. The predominant colors of the cattle are red and black. They feed on the wild paramo grass, and the beef is not only remarkably cheap, but superior in quality. The lasso is used in catching the animals, but not so skillfully as by the Gauchos of Rio Plata. It is a singular fact that cattle have followed men over the whole earth, from the coast of Africa to the highlands of Antisana. The same species is attacked by crocodiles and condors.
The atmospheric pressure is here so small that they frequently bleed at the nose and mouth when hunted. We have already given our experience in ascending high altitudes. We may add that while the pulse of Boussingault beat 106 pulsations at the height of 18,600 feet on Chimborazo, ours was 87 at 16,000 feet on Antisana. De Saussure says that a draught of liquor which would inebriate in the lowlands no longer has that effect on Mont Blanc. This appears to be true on the Andes; indeed, there is very little drunkenness in Quito. So the higher we perch our inebriate asylums, the better for the patients.
Near the hacienda is a little lake called Mica, on which we found a species of grebe, with wings so short it could not fly. Its legs, also, seem fitted only for paddling, and it goes ashore only to lay its eggs. It peeps like a gosling. Associated with them were penguins (in appearance); they were so shy we could not secure one. The query is, How came they there? Was this a centre of creation, or were the fowls upheaved with the Andes? They could not have flown or walked to this lofty lake, and there are no water-courses leading to it; it is surrounded with a dry, rolling waste, where only the condor lives. We turn to Darwin for an answer.[82]
The ragged Sincholagua[83] and romantic Rumiñagui follow Antisana, and then we find ourselves looking up at the most beautiful and most terrible of volcanoes. This is the far-famed Cotopaxi, or more properly Cutu-pacsi, meaning "a brilliant mass." Humboldt calls it the most regular and most picturesque of volcanic cones. It looks like a huge truncated cone rising out of the Valley of Quito, its sides deeply furrowed by the rivers of mud and water which have so often flowed out. The cone itself is about six thousand feet high. The east side is covered with snow, but the west is nearly bare, owing to the trade winds, which, sweeping across the continent, carry the ashes westward. Cotopaxi is the loftiest of active volcanoes, though its grand eruptions are a century apart, according to the general rule that the higher a volcano the less frequent its eruptions, but all the more terrible when they do occur. Imagine Vesuvius on the summit of Mont Blanc, and you have the altitude of Cotopaxi.
The top just reaches the middle point of density in the atmosphere, for at the height of three miles and a half the air below will balance that above. The crater has never been seen by man; the steepness of the sides and the depth of the ashes covering them render it inaccessible. The valiant Col. Hall tried it with scaling ladders, only to fail. The telescope reveals a parapet of scoria on the brim, as on Teneriffe. Humboldt's sketch of the volcano, so universally copied, is overdrawn. It makes the slope about 50°, while in truth it is nearer 30°. The apical angle is 122° 30'.[84]
Cotopaxi is slumbering now; or, as Mr. Coan says of Hilo, it is "in a state of solemn and thoughtful suspense." The only signs of life are the deep rumbling thunders and a cloud of smoke lazily issuing from the crater.[85] Sometimes at night the smoke looks like a pillar of fire, and fine ashes and sand often fall around the base, to the great annoyance of the farmers. On the south side is a huge rock of porphyry, called the Inca's Head. Tradition has it that this was the original summit of the volcano, torn off and hurled down by an eruption on the very day Atahuallpa was murdered by Pizarro. The last great eruption occurred in 1803, though so late as 1855 it tossed out stones, water, and sand. Heaps of ruins, piled up during the lapse of ages, are scattered for miles around the mountain, among them great boulders twenty feet square. In one place (Quinchevar) the accumulation is 600 feet deep. Between Cotopaxi and Sincholagua are numerous conical hills covering the paramo, reminding one of the mud volcanoes of Jorullo.
Pumice and trachyte are the most common rocks around this mountain, and these are augitic or porphyroid. Obsidian also occurs, though not on the immediate flank, but farther down near Chillo. In plowing, thousands of pieces as large as "flints" are turned up. The natives know nothing about their origin or use; the large specimens were anciently polished and used for mirror. But Cotopaxi is the great pumice-producing volcano. The new road up the valley cuts through a lofty hill formed by the successive eruptions; the section, presenting alternate layers of mud, ashes, and pumice, is a written history of the volcano.[86] The cone itself is evidently composed of similar beds super-imposed, and holding fragments of porphyry and trachyte. What is Vesuvius, four thousand feet high, to Cotopaxi, belching forth fire from a crater fifteen thousand feet higher, and shooting its contents three thousand feet above its snow-bound summit, with a voice of thunder heard six hundred miles!
Leaving this terrible "safety-valve" to the imprisoned fires under our feet, we travel along the wooded flanks and savage valleys of the Llanganati Mountains, whose lofty blue ridge is here and there pointed with snow.[87] It is universally believed that the Incas buried an immense quantity of gold in an artificial lake on the sides of this mountain during the Spanish invasion, and many an adventurous expedition has been made for it. The inhabitants will tell you of one Valverde, a Spaniard, who, from being very poor, had suddenly become very rich, which was attributed to his having married an Indian girl whose father showed him where the treasure was hidden, and accompanied him on various occasions to bring away portions of it; and that Valverde returned to Spain, and on his death-bed bequeathed the secret of his riches to the king. But since Padre Longo suddenly disappeared while leading an expedition, the timid Ecuadorians have been content with their poverty.[88]
And now we have reached the perfect cone of Tunguragua, the rival of Cotopaxi in symmetry and beauty.[89] It stands 16,500 feet above the Pacific, its upper part covered with a splendid robe of snow, while the sugar-cane grows in the romantic town of Baños, 10,000 feet below the summit. A cataract, 1500 feet high, comes down at three bounds from the edge of the snow to the warm valley beneath; and at Baños a hot ferruginous spring and a stream of ice-water flow out of the volcano side by side. Here, too, the fierce youth of the Pastassa, born on the pumice slopes of Cotopaxi, dashes through a deep tortuous chasm and down a precipice in hot haste, as if conscious of the long distance before it ere it reaches the Amazon and the ocean. Tunguragua was once a formidable mountain, for we discovered a great stream of lava reaching from the clouds around the summit to the orange-groves in the valley, and blocking up the rivers which tumble over it in beautiful cascades. It has been silent since 1780; but it can afford to rest, for then its activity lasted seven years.[90]
