As an illustration of this growth of interest a few comparisons can be made. Five years ago the total number of printed reports, pamphlets, and other publications distributed by the Pan American Union was approximately one hundred thousand. This year, the total will approximate nearly one million. None of these have been sent broadcast in a careless way. Five years ago there was little or no demand for the “Monthly Bulletin” of the Pan American Union; now the demand for it is greater than can be supplied. Then it was an uninteresting public document; to-day it is an attractive and instructive illustrated magazine, descriptive of the progress and development of the American nations. Five years ago the Pan American Union was housed in a small building, used formerly as a private dwelling, on the corner of Lafayette Square and Pennsylvania Avenue; to-day it occupies a building which a great French architect has described as combining beauty and utility better than any other public building of its cost in the world. The library of the Pan American Union, which is a practical collection of books useful to all persons who wish to study those countries, has been increased from twelve thousand to twenty-three thousand volumes, while its collection of photographs has grown from one thousand to eleven thousand. During this same period the foreign commerce of Latin America has grown from one billion seven hundred million dollars ($1,700,000,000) to two billion three hundred million dollars ($2,300,000,000). Of this, the share of the United States has increased from less than five hundred million dollars ($500,000,000) to nearly seven hundred million dollars ($700,000,000). The total annual contributions of all the American republics, including the United States, for the maintenance of the Pan American Union in 1906 was $54,000; now the total of their quotas for support approximates $125,000. All these facts I mention, not to call attention to the Pan American Union especially, but to emphasize with actual truth the evidences of the growth of interest throughout the world in the countries which are described in part by Mr. Van Dyke in this practical volume. If its reading stimulates further interest in them, the Pan American Union will be only too glad to furnish any information in its power.
