From book: The process of settlement and naturalization, together with the freedom of our institutions, and the fertility of our soil, have invited the denizens of the world, wherever assembled, or dispersed, to come among us and become fellow-citizens. And from every degree of latitude and of longitude, and from every isle and continent, under the whole heaven, the flood of emigration has poured in upon the United States....There has been nothing like it in appearance since the encampments of the Roman empire, or the tents of the crusaders. Democratic Review, June, 1852, page 566.
