It is an inspiring drama of colonization that has been enacted on this continent in a relatively short period. Its like was never witnessed before and can never be witnessed again. Thirty-three nationalities were represented in the significant group of American pilgrims that gathered at Mount Vernon on July 4, 1918, to place garlands of native flowers upon the tomb of Washington and to pledge their honor and loyalty to the nation of their adoption. This event is symbolic of the great fact that the United States is, after all, a nation of immigrants, among whom the word foreigner is descriptive of an attitude of mind rather than of a place of birth.
