And this leads us to remember that, if the Louisiana purchase revolutionized our national outlook, our constitutional attitude, and our sectional control, it quite as radically changed our national texture. From that hour to this we have called to the masses of Europe for help to develop the wilderness, and they have come by millions, until now the men and women of Revolutionary stock probably number less than fifteen millions in the entire country. These later Americans have, like the migrations of the Norsemen in central and southern Europe, proved so conservative in their Americanism that they outrun their predecessors in loyalty to its essentials. They made the Union as it now is, in a very high sense, and there is no question that in the throes of civil war it was their blood which flowed at least as freely as ours in its defense. It is they who have kept us from developing on colonial lines and have made us a nation separate and apart. This it is which has prevented the powerful influence of Great Britain from inundating us, while simultaneously two English-speaking peoples have reacted one upon the other in their radical differences to keep aflame the zeal for exploration, beneficent occupation, and general exploitation of the globe in the interests of a high civilization. The localities of the Union have been stimulated into such activities that manufactures and agriculture have run a mighty race; commerce alone lags, and no wonder, for Louisiana gave us a land world of our own, a home market more valuable than both the Indies or the continental mass of the Far East.
