The peace arranged by President Diaz had brought foreign capital by the billion to aid the internal development of the country, and of this money more had come from the United States than from any other nation.

Nor was it financial aid alone which had gone across the border.

There was but little American colonization, it is true, but business managers, engineers, mine foremen, and ranch superintendents formed thousands of links binding the nations together.

The climax of intimacy seemed reached when, in 1910, a general treaty of arbitration was made after President Taft and President Diaz had met at El Paso on the Mexican border in a personal conference.

A personal interview between the President of the United States and the chief of a foreign state was almost unique in American history, owing to the convention that the President should not depart from the national territory.
It was, therefore, with a bitter sense of disappointment that Americans heard of the revolution inaugurated in 1910 by Francisco Madero.
