Of all the great Expositions held in the United States to celebrate some distinct occurrence or achievement in the history of the country, none has assumed the importance or splendour of the World's Fair at San Francisco, created to commemorate America's immeasurable service to the cause of humanity by the construction of the Panama Canal to link up the Atlantic and Pacific oceans. Conceived and decided upon in times of general peace, most of the nations of the earth were invited to participate; and though laboring at the time under certain difficulties induced by universally disturbed economic conditions, many of the countries subordinated these considerations to the higher purpose of cementing the bonds of international friendship by accepting the invitation of the United States to take part in the great Exposition of San Francisco, formed to crown the colossal work initiated by Ferdinand de Lesseps and carried into execution by American skill, labor and courage. Not least amongst the countries willing to make sacrifices to share in this noble work was the Argentine Republic which, in the face of many obstacles to adequate representation, at once entered into the spirit of the undertaking and after assembling its leading authorities in all the branches of national arts and industries, decided to assume its appropriate part in the glorification of the American Continent by the effort to show that the nations of the south were advancing step by step with the great Republic of the north. Preliminary action was at once taken to organize influential committees representing all the States and Territories of the Republic, an immense sum of money was voted by Congress and full preparations were set on foot to secure a practical and eloquent manifestation of the phenomenal progress and of the social and political economy of the Argentine Republic. No sooner had these measures been adopted than a series of perturbations, culminating in the outbreak of the war in Europe, occurred to create an unfavorable ambient and to sow doubts and mistrust forshadowing failure for the great enterprise. In spite, however, of the fears and even of the opposition thus created, the Argentine Government through its organized Committees proceeded uninterruptedly with the completion of its plans and has been able to organize the most important representation it has yet had in any foreign Exposition.
