Not only have war conditions favoured a more clearly defined national development, both economic and political, in each of the states. These conditions also conduce to closer and more real intercourse between the Latin-American states. There has been on the one hand a national consolidation in each republic: but there has also been a movement towards international consolidation in the Latin-American world. The war has drawn these republics closer together and has taught them to feel their need of one another, to supply one another's needs and to recognise a nearer community of social and political interests. The sentiment of _Americanismo_ is more than a sentiment: it is growing into a solid fact. Apart from the war, there are many indications of a kindlier and more intimate intercourse. The Universities of Argentina, Chile and Uruguay exchange professors. Brazil and Uruguay agree concerning navigation of the Lago de Merim and the river Jaguarão; and also arrange a seasonal migration of labourers, who work from April to September on the São Pãolo coffee estates and pass the other half-year working on Uruguayan estancias. The same two republics adjust a financial matter through the foundation of a joint Brazilian-Uruguayan agricultural college. Uruguay has declared that an injury to any South American country is an injury to them all. Envoys from the neighbour-republics visit Bolivia to salute the newly-elected Bolivian President, among them an envoy from the United States. Junior embassies, hardly less interesting in character, are the visits of boy scouts from capital to capital. The five tropical republics which hail Bolívar as Liberator lately clasped hands in a joint celebration of his memory, and at the same time concluded a commercial agreement concerning trade marks and similar matters. The study of history, now actively pursued by competent scholars in all the republics, is a unifying as well as a humanising power: for the student who explores or writes the early history of his own republic necessarily treats the history of all Latin America. The history of the struggle for South American emancipation is a single epic. And a pleasing symbol of this historical unity is to be seen in the portrait of the Argentine commander San Martín and of the Venezuelan Bolívar imprinted on the postage stamps of Peru. The railroad helps this movement. The trans-Andine railway is a link of peaceful intercourse between Chile and Argentina. A direct mail train service has been established between Rio and Montevideo and also between Rio and Buenos Aires. There is a prospect that the last difficult link to connect the railway systems of Bolivia and Argentina will soon be supplied. This is an imperfect and rather haphazard list of symptoms of a natural and tranquil movement towards international unity, which accompanies and supplements a more vigorous economic and political development within the several states. The war situation has favoured this movement.
