=The Central Railway.= In spite of the enormous difficulties of making a roadbed up a steep cañon or on the face of a bluff, bridging torrents, and tunneling side buttresses and mountain ranges, two railroads, both monuments of skill and perseverance, climb from the coast to the plateau, the Central, and the Southern Railways of Peru. The first, a standard gauge line from Callao begun in 1870 by the American financier, Henry Meiggs, was in 1876 completed as far as Chicla, 88 miles. On account of troubles resulting from the Chilian war, it did not reach Oroya, long the terminus, till 1893. The road follows up the Rimac Valley, which, however, is so steep and narrow that detours into side valleys are necessary, as into the Verrugas, which is crossed by a bridge 225 feet high, one of 67 bridges on the journey. Many curves, tunnels, and V’s are also needed to gain in 7¹⁄₂ hours, with no more than a 4 per cent grade, an elevation of 15,665 feet at a distance from the sea in a straight line of less than 100 miles. Frequently the floor of the cañon has room only for the rushing stream, and the road passes high up on the slope or cliff, at one point, 575 feet, or through one of the 57 tunnels. Some of the cliffs are more than one third of a mile in perpendicular height. The road is considered in some respects the most wonderful of the world’s railways. A branch 10 miles long from Ticlio to Morococha, reaching an altitude of 15,865 feet, a trifle above that of Mont Blanc, is absolutely the highest railway in the world. At Ticlio, the highest point of the main line, is entered the Galera tunnel, three quarters of a mile long, which cuts through the continental divide. The road then descends to Oroya, altitude 12,178 feet. In taking the trip for pleasure or business one not absolutely sure of the soundness of his heart should have it examined, or at least should stop over two days at Matucana, 7788 feet, where there is a fairly comfortable hotel. Any one is liable to suffer somewhat from _soroche_, which may be avoided by the stop-over. In general persons of good constitution, not too full blooded, will be troubled only by a headache, perhaps accompanied by nausea, and those who are careful to avoid rapid walking or over exertion of any kind for a day or two after arrival above, and who do not overeat before setting out on the journey or afterwards may suffer no inconvenience whatever. No liquor of any kind should be used except in collapse from heart failure. Ammonia is desirable in case of headache.
