Marks of inland expansion.

On the other hand, that growing people which finds its coastward advance blocked, and is therefore restricted to landward expansion, seizes upon every natural feature that will aid its purpose. It utilizes every valley highway and navigable river, as the Russians did in the case of the Dnieper, Don, Volga, Kama and Northern Dwina in their radial expansion from the Muscovite center at Moscow, and as later they used the icy streams of Siberia in their progress toward the Pacific; or as the Americans in their trans-continental advance used the Ohio, Tennessee, the Great Lakes, and the Missouri. They reach out toward every mountain pass leading to some choice ultramontane highway. Bulges or projecting angles of their frontier indicate the path they plan to follow, and always include or aim at some natural feature which will facilitate their territorial growth. The acquisition of the province of Ticino in 1512 gave the Swiss Confederation a foothold upon Lake Maggiore, perhaps the most important waterway of northern Italy, and the possession of the Val Leventina, which now carries the St. Gotthard Railroad down to the plains of the Po. Every bulge of Russia's Asiatic frontier, whether in the Trans-Caucasus toward the Mesopotamian basin and the Persian Gulf, or up the Murghab and Tedjend rivers toward the gates of Herat, is directed at some mountain pass and an outlet seaward beyond.

If this process of growth bring a people to the borders of a desert, there they halt perhaps for a time, but only, as it were, to take breath for a stride across the sand to the nearest oasis. The ancient Egyptians advanced by a chain of oases—Siwa, Angila, Sella and Sokna, across the Libyan Desert to the Syrtis Minor. The Russians in the last twenty-five years have spread across the arid wastes of Turkestan by way of the fertile spots of Khiva, Bukhara and Merv to the irrigated slopes of the Hindu Kush and Tian Shan Mountains. The French extended the boundaries of Algiers southward into the desert to include the caravan routes focusing at the great oases of Twat and Tidekelt, years before their recent appropriation of the western Sahara.

Marks of decline.

As territorial expansion is the mark of growth, so the sign of decline is the relinquishment of land that is valuable or necessary to a people's well-being. The gradual retreat of the Tartars and in part also of the Kirghis tribes from their best pasture lands along the Volga into the desert or steppes indicates their decrease of power, just as the withdrawal of the Indians from their hunting grounds in forest and prairie was the beginning of their decay. Bolivia maimed herself for all time when in 1884 she relinquished to Chile her one hundred and eighty miles of coast between the Rio Lao and the twenty-fourth parallel. Her repeated efforts later to recover at least one seaport on the Pacific indicate her own estimate of the loss by which she was limited to an inland location, and deprived of her maritime periphery.[286]

Interpretation of scattered and marginal location.

The habits of a people and the consequent demands which they make upon their environment must be taken into account in judging whether or not a restricted geographical location is indicative of a retrograde process. The narrow marginal distribution of the Haida, Tlingit, and Tsimshean Indians on the islands and coastal strips of northwestern America means simply the selection of sites most congenial to those inveterate fisher tribes. The fact that the English in the vicinity of the Newfoundland Banks settled on a narrow rim of coast in order to exploit the fisheries, while the French peasants penetrated into the interior forests and farmlands of Canada, was no sign of territorial decline. English and French were both on the forward march, each in their own way. The scattered peripheral location of the Phoenician trading stations and later of the Greek colonies on the shores of the Mediterranean was the expression of the trading and maritime activity of those two peoples. Centuries later a similar distribution of Arab posts along the coast of East Africa, Madagascar and the western islands of the Sunda Archipelago indicated the great commercial expansion of the Mohammedan traders of Oman and Yemen. The lack came when this distribution, normal as a preliminary form, bore no fruit in the occupation of wide territorial bases. [See map page 251.]
