ARGENTINE 35 the frontier. Early in its history Argentine encouraged emigration from Europe, using as an inducement the free grant of public lands, which proved especially attractive to the Italian and Spaniard. In fact the pre ponderance of the Italian in the business and social life, due to this movement has had a noticeable effect on the Spanish language as spoken in this country. From 1857 to 1913 the total of newcomers amounted to 4,781,653, many of whom became landholders and began at once to contribute to the growth and wealth of the country. The population to-day is 7.8 persons per square mile as against 32.31 per square mile in the United States. More than 300,000 persons migrate to this country each year. The chief characteristic of the physical formation of the Argentine is its vast pampas or plains stretching from the Rio de la Plata to the west, terminating in the foothills of the Andes, or the Cordilleras. Perhaps no part of the earth’s surface has such flat, smooth, treeless plains as here confront the traveller.
