It has been calculated that motive force can thus be obtained at a cost of less than 4%u. per unit of horse-power per hour. The Peruvian railroads over the Andes climb the mountains by sharp grades and turns. One road winds up the mountains in a zigzag and oftentimes almost circular path, and at one point there are two tunnels through the side of the peak, one directly above the other in the same lateral direction. The rarefied atmosphere at the great elevation reached on the summit presented manv new features in railroading, as a locomotive had never before been worked at these heights. It was supposed by engineers generally that it would be impossible to keep up steam above 8,000 or 10,000 feet. This problem was solved in a very simple manner. At great elevations it was merely necessary to introduce into the furnace a greater quantity of air in a given time than at the sea level, and the simple operation of opening the dampers wider accomplished this result.
