3. Immigration is leading millions to study the English tongue. This is of great importance if the multitudes of future Americans are to understand and appropriate the principles of democracy and Protestantism enshrined in English literature. The German and Scandinavian and other tongues will contribute to America the best they possess, while at the same time they are themselves greatly enriched.

4. The mingling races are challenging America to demonstrate the truth of those principles of freedom and democracy of which such proud boast has been made in days gone by. The principles of democracy can scarcely be thoroughly and finally tested among people who are of the same race and have a common speech and who have a more or less common purpose. Democracy can be adequately tested only amid the complexities of race and clan, of diverse speech and history. These principles of democracy have never been literally applied in any large way yet, but one of God's greatest challenges to the manhood of the United States and Canada to-day is that literal application of the principles of democracy shall be made to the whole population gathered within their vast domains. Here is a call for statesmanship and spiritual passion worthy of the finest life America has produced.

II. Mexico and Central America

These lands lying to the south are America's nearest foreign missionary field.

In each case in which the number of missionaries is mentioned in this volume, unless otherwise stated, it may be understood to include all missionaries, both men and women, except wives of missionaries. This is thought to be fair, not because missionaries' wives are not as devoted as their husbands or other workers, but because it is not to be expected that a woman with household cares should be responsible for the same amount of direct Christian work that is expected of other workers on the field. In other words, the family or the single worker is considered the unit.

The people in Mexico are nominally Roman Catholic, the census returns showing thirteen and a half millions of that faith. Conditions are difficult for Protestant missions. The population of Mexico is more than fifteen millions. Among these millions there are 249 representatives of Protestant Christianity. In 1895 more than ten millions in Mexico could neither read nor write, and while conditions have improved somewhat since then, it is safe to say that seven out of every ten of the population are illiterate. In Central America, including Panama, there are 96 missionaries.

These simple facts will illustrate the truth that there are still parts of the North American continent inadequately cultivated by the Protestant churches.
