=Bolivia-Antofagasta Railway.= The journey to La Paz from Antofagasta, on the Chilian coast 400 miles below Arica, occupies two days for the 718 miles. This, the earliest of Bolivian railways, with Oruro for years as the terminus, in 1911 was continued to La Paz, _i.e._, to Viacha (15 miles from La Paz), where it meets the road from Guaqui, the two forming a long link in the Pan American chain. The later road now has its own line into the city. At Uyuni, where there is a Custom House and a change of cars, the road turns off towards Chile. From Ollague on the Chilian border, a 58-mile branch runs to the Collahuasi copper mines, among the richest in the world. A Bolivian extension is now being made along the plateau to connect with the Argentine road from La Quiaca to Buenos Aires. Already Atocha has been reached; 60 miles remain to Tupiza, and 66 more to La Quiaca, the terminus of the Argentine railway to the border. An automobile service is operated in the dry or winter season from Atocha to La Quiaca, making the journey in eight hours. The rest of the year one goes on muleback. Thus by the weekly train from La Quiaca to Buenos Aires in 48 hours, the entire journey, 2000 miles, may be made from La Paz much more quickly than by way of Chile, in case one does not wish to go there. This route also serves when the Trans-Andine is blocked by the winter snow. =Other Argentine connections= are planned. A branch railway is to be built from La Quiaca or possibly from Orán to Tarija, about 82 miles; meanwhile it is expected to construct an automobile road for the service. A railway extension from the Argentine boundary farther east, hoped for in the near future, is from Embarcación to Yacuiba, thence to Santa Cruz, thus opening the cattle region of the Chaco, of Chuquisaca, and Santa Cruz for the export of cattle through Buenos Aires. =Several Branches.= Farther north important branches to the interior are already in operation. The first, opened in 1912, was from the station, Rio Mulato, 130 miles south of Oruro, to far famed Potosí. This section, 108 miles long, climbs to a height of 15,814 feet, the second highest altitude reached by rail, following the Morococha branch of the Central Peruvian. The cost was over $8,000,000, the maximum grade three per cent. The trip occupies eight hours; there is weekly service. The Oruro-Cochabamba Line was completed in 1917; its length 132 miles, its cost above $10,000,000. It crosses the Cordillera at about 14,000 feet. This road is equally important, opening up a fine agricultural and well populated district. Its fine scenic attractions should allure the tourist. Food is very expensive on the plateau, but with improved access to the warmer sections, lower prices and greater variety of fruits and vegetables may be expected above.
