Among highly civilized agricultural and industrial peoples, on the other hand, a vast territorial policy is at once cause and effect of national growth; it is at once an innate tendency and a conscious purpose tenaciously followed. It makes use of trade and diplomacy, of scientific invention and technical improvement, to achieve its aims. It becomes an accepted mark of political vigor and an ideal even among peoples who have failed to enlarge their narrow base. The model of Russian expansion on the Pacific was quickly followed by awakened Japan, stirred out of her insular complacence by the threat of Muscovite encroachment. Germany and Italy, each strengthened and enlarged as to national outlook by recent political unification, have elbowed their way into the crowded colonial field. The French, though not expansionists as individuals, have an excellent capacity for collective action when directed by government. The officials whom Louis XIV sent to Canada in the seventeenth century executed large schemes of empire reflecting the dilation of French frontiers in Europe. These ideals of expansion seem to have been communicated by the power of example, or the threat of danger in them, to the English colonists in Virginia and Pennsylvania, and later to Washington and Jefferson. [Sidenote: The mind of colonials.] The best type of colonial expansion is found among the English-speaking people of America, Australia and South Africa. Their spacial ideas are built on a big scale. Distances do not daunt them. The man who could conceive a Cape-to-Cairo railroad, with all the schemes of territorial aggrandizement therein implied, had a mind that took continents for its units of measure; and he found a fitting monument in a province of imperial proportions whereon was inscribed his name. Bryce tells us that in South Africa the social circle of "the best people" includes Pretoria, Johannesburg, Kimberley, Bloemfontein and Cape Town--a social circle with a diameter of a thousand miles![323] The spirit of our western frontier, so long as there was a frontier, was the spirit of movement, of the conquest of space. It found its expression in the history of the Wilderness Road and the Oregon Trail. When the center of population in the United States still lingered on the shore of Chesapeake Bay, and the frontier of continuous settlement had not advanced beyond the present western boundary of Virginia and Pennsylvania, the spacious mind of Thomas Jefferson foresaw the Mississippi Valley as the inevitable and necessary possession of the American people, and looked upon the trade of the far-off Columbia River as a natural feeder of the Mississippi commerce.[324]
