The water supply and sewer system of the capital are likewise under the direction of the national government. Few cities of the world have a better service. The water is taken from the La Plata River far enough up to avoid any chance of pollution. It is obtained from wells which are driven beneath the bottom of the river, and the water is pumped through tunnels to a central station. Here it is filtered and then distributed to all sections of the city. The central reservoir, called the Aguas Corrientes, is in the heart of the city. With its imposing brick and terra cotta facing on every side, it looks like a magnificent palace, and so I thought it at first sight. Inside, however, it consists only of immense tanks from which the water gravitates over the city. This shell constructed for the water tanks cost the municipality almost a million dollars, and it is all done for the sole purpose of adding to the artistic beauty of the capital. CHAPTER III THE CAMP The flat pampas, or plains, which constitute almost ninety per cent. of the Argentine Republic that is suitable for agriculture and pasture, are generally called the Camp. The name is derived from the Spanish word _campo_, which means country. The Camp is the mainspring of Argentine prosperity. The marble palace of the millionaire, as well as the mud hovel of the immigrant, has to thank this rich soil of the _campo_ for its foundation. It is upon this land that the republic has grown and prospered. Its eccentricities and its products are watched with all the anxiety usually lavished upon a baby by anxious parents; and it is a pretty big infant, for the Camp comprises millions upon millions of fertile acres.
