Where the wind is most variable, visiting entire countries with storms, to the great destruction of lives and property, the result is a stirring up of the survivors to exertions that cannot fail to be strengthening both to body and to mind, and of direct benefit to life in general. At the same time that the people of Holland were engaged in forcing back the ocean, they won their political liberty. In another part of the North Sea coast the Frisians receded farther and farther south, owing to the invasions of the sea and the attacks of the natives of Holstein. The tempest that scattered the armada of Philip II. was one of the most important political events of the time; and it is not to be denied that the snowstorm in Prussian Eylau, at the beginning of the battle in which Napoleon suffered his first defeat, contributed not a little to the result.
One of the Greatest Problems
Acclimatisation is one of the greatest of human problems. In order that a nation shall expand from one zone into another, it must be capable of adapting itself to new climates. The human race is, as a whole, one of the most adaptable of all animal species to different conditions of life; it is diffused through all zones and all altitudes up to about thirteen thousand feet above the level of the sea. But single nations are accustomed to fixed zones and portions of zones; and long residence in foreign climates leads to illness and loss of life.
Climate and Will-Power
In some races the individuals are of a more rigid constitution than in others, and are thus less capable of adaptation. Chinamen and Jews adapt themselves to different climates far more easily than do Germans, upon whom residence in the southern part of Spain even, and to a still greater degree in Northern Africa, is followed by injurious effects. The constant outbreaks of destructive disease before which the German troops withered away are to be counted amongst the greatest obstacles opposed to the absorption of Italy into the German Empire. During the Spanish discoveries and conquests in America in the sixteenth century, whole armies wasted away to mere handfuls. The greatest hindrances to German colonisation in Venezuela are climatic diseases. Medical science has, to be sure, pointed out such deleterious influences as may be traced to unsuitable dwelling-places, nutrition, clothing, etc.; and the losses to Europe of soldiers and officials in the tropics have been greatly reduced. But even to-day deaths, illnesses, and furloughs make up the chief items in the reports sent in from every colony in the tropics. British India can only be governed from the hills, where the officials dwell during the greater part of the year.
Climatic influence is not limited to bodily diseases. One of the first effects of life in warm climates upon men accustomed to cold regions is relaxation of what is known as will-power. Even the Piedmontese soldier loses his erect carriage in a Neapolitan or Sicilian garrison. Englishmen in India count on an ability to perform only half the amount of work they would be capable of at home. Many inhabitants of northern countries escape the bodily diseases of the tropics; but scarcely one man of an entire nation is able to resist the more subtle alterations in spirit.
The Peoples of North and South
Their historical influence extends only the deeper for it. The conquering nations that advance from north to south have invariably forfeited their power, determination, and activity. The original character of the Aryans who descended into the lowlands of India has been lost. A foreign spirit rings through the Vedic hymns. West Goths and Vandals alike lost their nationalities in Northern Africa and Spain, as the Lombards lost theirs in Italy. In spite of all emigration, immigration, and wandering hither and thither, there always remains a certain fixed difference between the inhabitants of colder and those of warmer countries; it is the nature of the land, moulding the more ductile character of a people into its own form. There are differences also between the northern and the southern stocks of the same race, and thus climate exerts here greater and there lesser influence upon nations and their destinies.
Since it lies in the nature of climatic influences to produce homogeneity among those peoples who inhabit extensive regions of similar mean annual temperatures, it follows that a unifying effect is also produced on political divisions that might otherwise be inclined to separate from one another. In the first place, a similar climate creates similar conditions of life, and thus the northern and southern races of each hemisphere, with their temperate and their hot climates, differ widely. Climate is also the cause of similar conditions of production over large territories. Leroy-Beaulieu rightly mentioned climate—above all, the winter, during which almost every year the whole land from north to south is covered with snow—as next in importance to the configuration of the country in its unifying, cohesive effects on the Russian Empire. Winters are not rare during which it is possible to journey from Astrachan to Archangel in sledges; and both the Sea of Azov and the northern part of the Caspian Sea are frozen over during the cold months, as well as the Bay of Finland, the Dnieper as well as the Dwina.
