an altitude of from eight thousand feet and upwards that there arose such civilization as the ancient Peruvians developed: and its origin here rather than elsewhere in South America may be mainly due to favourable climatic conditions. There was enough rain to provide grass for animals and make tillage possible, and enough warmth to enable men to live in health, yet not enough either of rain or of heat to make nature too strong for man and to enfeeble man's capacities for work.
Temperature and rainfall resembled generally those of the plateau of Mexico, a region somewhat lower, but farther from the Equator: and it was under similarly fortunate conditions of climate and agricultural possibilities that the races inhabiting those highlands had made, when Europeans arrived, some considerable advances in the arts of life. This central Peruvian area is to-day, with the exception of the irrigated banks of a few streams reaching the Pacific, the only part of the country where either an agricultural or a pastoral population can support itself. The rest of Peru depends upon its mines, chiefly of silver and copper, – a source of wealth uncertain at best. It is only in a few valleys, the most productive of which I am going to describe, that the agricultural population occupies any large continuous area. As a rule each community is confined to its own valley and cut off from the others either by mountains or by high, bare ridges on which only sheep can be kept, most of them too high and bleak even for pasture.15
There is no better way of conveying some notion of the character of this central region, the true Peru, than by describing the country through which I passed by railway from Arequipa eastward to Lake Titicaca and thence northward to Cuzco, the ancient Inca capital. This railroad follows the line of the most important through route which war and commerce took in pre-Conquest times. It is the Southern Railroad of Peru, the main highway of the country. The section from Mollendo to the plateau at Juliaca was built many years ago, but the extension to Cuzco had been completed and opened less than a year before our visit. Both sections have been constructed by engineers from the United States, and the way in which the difficulties of extremely steep ascents and cuttings along precipitous slopes have been overcome reflects great credit on their skill. The gauge is the normal one. The line is owned by the Peruvian Corporation, a company registered in London, and under the energetic management of North American engineers it is doing a great deal to open up regions in which till some ten years ago there was not even a road fit for wheels. The passenger traffic is of course very small, and passenger trains run only once a day to Arequipa and thrice a week to Juliaca and Cuzco.
Quitting Arequipa on the southwestern side, the line winds up to the north and then to the east across a rugged and dreary region of rocky hill slopes, pierced by deep gorges through some of which brooks come down, fed by snow beds far above. It follows the line of a canyon, and wherever there is level ground at the bottom, some bright green strips of cultivation appear on the margin of the stream, with a few Indian huts; so even these upper regions, cold and desolate as they are, are not so wholly desolate as the Pampa below. The view looking back over the city lying in its green oasis, with a stony desert all round, is superb. As we climb higher, the mass of Ampato and other giants of the western Cordillera deep with snow, rise in the northwest, while westward one sees beyond the reddish grey mountains through which we had mounted to Arequipa from the desert Pampa, the gleaming sands of that desert, and behind them again, just on the horizon, the long, low bank of clouds that covers the Coast Range. Here at nine or ten thousand feet, one looks over the white upper surface of these clouds. Resting on the western edge of the Pampa, they stretch far out over the Pacific and veil it from sight. Thus steadily mounting, and seeing below in a ravine the hamlet of Yura, where is a mineral spring whose pleasantly effervescent water is drunk all over Peru, the train winds round the northern flank of Chachani under its huge black precipices. Behind it and behind El Misti, which shews as a symmetrical cone on this side as well as on that turned towards Arequipa, we entered at a height of about eleven thousand feet a region typical of the Peruvian uplands. There was plenty of coarse grass, studded with alpine flowers, a few belonging to European genera. Llamas and alpacas were grazing on the slopes, herded by Indians: there were sheep, and a few cattle, and in one place we thought we caught sight among low bushes of a group of vicuñas. This is a creature like the llama, but smaller, and useless as a beast of burden, because untameable. It roams over the hills between eleven thousand and fifteen thousand feet, and produces the finest of all the South American wools, of a delicate light brown tint, silky and soft as the fur of a chinchilla.
The scenery was strange and wild, not without a certain sombre grandeur. Below was the Chile River, the same which passes Arequipa, and to which we had returned after our circuit round Chachani. It was flowing in a deep channel which it had cut out for itself between walls of black lava: and the wide bare hollows beyond were filled with old lava streams and scattered ridges and piles of rock. To the southwest El Misti and his two mighty neighbours shut in the valley, and away to the south huge mountains, among them one conspicuous volcanic cone, were dimly seen, snowy summits mingled with the gathering clouds, for at this height rain and snow showers are frequent. The cone was probably Ubinas, the only active volcano in this neighbourhood, about sixteen thousand feet high.
Still mounting to the eastward, the line rose over gentler slopes to a broad, bleak, and wind-swept ridge where tiny rivulets welling up out of pools in the yellowish grass were flowing west to the Pacific and eastward to the inland basin of Lake Titicaca. Large white birds like wild geese were fluttering over us. Here were a few huts of the Indian shepherds near the buildings of the station; and here a cross marked the Cumbre or top of the pass, which is called the Crucero Alto, 14,666 feet above sea level. Higher ground cut off the view to the north and clouds obscured the view to the east, but to the south we could discern some of the lofty summits of the western Cordillera on the watershed of which we stood. Thunderstorms were growling on both sides, and out of black clouds far in the northwest towards Coropuna came bright flashes of chain lightning. At this height the country is comparatively open and the valleys shallow, and this, along with the wonderful clearness of the air, enables the eye to range to a vast distance. This northwestern thunderstorm which we were watching was possibly a hundred miles away. We were awed by the mere vastness of the landscape, in which we looked over tracts it would take many days' journeys to traverse, and saw mountains eighteen thousand feet high separated by nameless valleys no one ever enters, with hills and rocks tumbled about in chaotic confusion, as though the work of world-shaping had here just begun. Stepping out into the bitter wind, we walked about awaiting signs of the Soroche or mountain sickness so much dreaded by Andean travellers, especially when they come straight up from the coast to this vast height, as high as the Matterhorn or the highest peaks of the Rocky Mountains. The air was very cold and very thin, seeming not to fill the lungs. But nothing happened.
From the Crucero Alto the railway descends rapidly for two thousand feet past two large lakes, embosomed in steep green hills – they reminded me of Loch Garve in Ross-shire – till it reaches a wide, bare, desolate flat, evidently part of the former bed of Lake Titicaca, which was once far larger than it is to-day. Here we were in that central plateau which the people call the Puno and which surrounds the lake, its lower part cultivated and peopled. At the large village of Juliaca, whence a branch line runs to the port of Puno on the lake farther to the southeast, the main line turns off to the north, still over the flat land which, where not too marshy, is under tillage. The inhabitants were all Indians, and only at Tirapata, which is a point of supply for the mines on the eastern slope of the mountains, were white people to be seen. Far to the northeast, perhaps one hundred miles away, could be discerned a serrated line of snowy mountains, part of the eastern Cordillera which divides the Titicaca basin from the Amazonian valleys. At last the hills begin to close in and the plain becomes a valley, narrowing as we travel farther north till, at a sharp bend in the valley which opens out a new landscape, we pass under a rock tower sixteen thousand feet high, like one of the aiguilles of Mont Blanc immensely magnified, and see in front of us a magnificent mountain mass streaming with glaciers. Two great peaks of from eighteen thousand to nineteen thousand feet are visible on this side, the easternmost one a long snow ridge resembling the Lyskamm above Zermatt; and behind it there appears a still loftier one which may approach or exceed twenty thousand feet. This is the Sierra of Vilcanota, the central knot of the mountain system of Peru, as in it branches of the western inosculate with those of the eastern Cordillera. Though very steep, the highest peaks seemed to me, surveying them from a distance of
