At Tucuman connection is made with the Central Northern Railway, a national railway of more than twelve hundred miles in length. It starts at Santa Fé and almost parallels the Central Argentine to Tucuman, at no point being distant more than fifty miles. It is a narrow gauge track. Leaving Tucuman it runs in a general northerly direction, but with many twists and turns in order to avoid the more mountainous sections of the districts through which it passes. At Tala the frontier of Salta is crossed at an elevation of two thousand six hundred and seventy feet, and a short distance further the elevation has increased to over three thousand feet. It then descends to the little town of Rosario de la Frontera noted for its thermal springs. At Guenas, one hundred and eighty miles from Tucuman, a branch runs to Salta, the capital of the province. This is a neat, well-paved city of about thirty thousand people with the usual public buildings and churches of a provincial capital. San Francisco church has a tower over two hundred feet in height which is pointed to with pride by the inhabitants. This city is very old, having been founded as early as 1582 under the name of New Seville. Pampa Blanca (the white pampa), is the first station in the province of Jujuy. Near here another branch is headed for the rather important town of Oran, but the main line soon reaches the capital. Jujuy for a long time was the northerly terminus of the Argentine railway system. This is the highest town in the republic, and, although near the tropics, the altitude gives this little city a fine and healthful climate. It has a population of ten thousand and is distant from Buenos Aires one thousand miles. The town has nothing to distinguish it, but the surrounding scenery is very beautiful. Hill and valley, wood and plain all contribute to make up a most enchanting landscape. The Rio Grande River runs through the town. It is the general bathing place as well as furnishing the power for the electric light and some mills located there. There are many thermal springs in the vicinity which are said to have splendid medicinal properties. The most noted are those of Los Reyes, the kings. There are four springs, one above another, the water being at a temperature of one hundred and twenty-five degrees Fahrenheit.
