South America is, pre-eminently, the coming continent. It is more thinly settled than any other part of the world. At least six million miles of its territory are suitable for immigrants--double the available territory of the United States. "No other tract of good land exists that is so large and so unoccupied as South America." [Footnote: Dr. Wood, Lima, Peru, in "Protestant Missions in South America."] "One of the most marvellous of activities in the development of virgin lands is in progress. It is greater than that of Siberia, of Australia, or the Canadian North-West." [Footnote: The Outlook, March, 1908.] Emigrants are pouring into the continent from crowded Europe, the old order of things is quickly passing away, and docks and railroads are being built. Bolivia is spending more than fifty million dollars in new work. Argentina and Chile are pushing lines in all directions. Brazil is preparing to penetrate her vast jungles, and all this means enormous expense, for the highest points and most difficult construction that have ever been encountered are found in Peru, and between Chile and Argentina there has been constructed the longest tunnel in the world. [Footnote: One railway ascends to the height of 12,800 feet.] Most important of all, the old medieval Romanism of the Dark Ages is losing its grip upon the masses, and slowly, but surely, the leaven is working which will, before another decade, bring South America to the forefront of the nations. The economic possibilities of South America cannot be overestimated. It is a continent of vast and varied possibilities. There are still districts as large as the German Empire entirely unexplored, and tribes of Indians who do not yet know that America has been "discovered."
