A LONGITUDINAL JOURNEY THROUGH CHILE 225 Photograph by Richard B. Iloit NITRATE FIELD ENGINEERS ON A TOUR OF INSPECTION These fields of northern Chile stretch for several hundred miles along the pampas' western rim. Operated for the most part by Chilean and British capital, 129 of these nitrate estab lishments, or oficinas, as they are known locally, are scattered over the pampa back of Pisagua, Iquique, and Antofagasta. The engineers of one of these establishments are making their rounds in a mule-drawn car furnished with a brake and two good seats, but no springs. © Publishers' Photo Service A DESERT TRAIN WITH IRON WIIEELS SUPPLANTING RUBBER TIRES The Chilean longitudinal railroad does not extend north of Pisagua, but many of the nitrate establishments have their local railways. The American automobile is here supplanting the old mule-team.
