There are other characteristics different from, but generally combined with color, which are influenced by constitutional varieties. The hair usually harmonizes with the complexion, and, like it, shows the influence of climate. In cold countries, the natural covering of every animal becomes rich and soft; the plentiful locks and manly beard of the European show a marked contrast to the coarse and scanty hair of the inhabitants of tropical countries. The development of mental power and refined habits of life have also a strong but slow effect upon the outward form.[214] Certain African nations of a higher intelligence and civilization than their rude neighbors, show much less of the peculiarities of the negro features. The refined Hindoo displays a delicate form and expression under his dark complexion. The black color and the negro features are accidentally not necessarily connected, and it seems to require both climate and inferiority of intellect to unite them in the same race.
When circumstances of climate or situation have effected peculiar appearances in a nation or tribe, the results will long survive the causes when people are removed to widely-different latitudes: a dark color is not easily effaced, even under the influence of moderate temperature and heightened civilization. For these reasons, there appear many cases where the complexion of the inhabitants and the climate of the country do not correspond, but the original characteristics will be found undergoing the process of gradual change, ultimately adapting themselves to their new country and situation.[215] The marked and peculiar countenances of the once "chosen people" vary, in color at least, wherever they are seen over the world, although uninfluenced by any admixture of alien blood. In England the children of Israel and the descendant of the Saxon are alike of a fair complexion, and on the banks of the Nile the Jew and the Egyptian show the same swarthy hue.[216]
At first sight this American race would appear to offer evidence against the supposed influence of climate upon color, as one general form and complexion prevail in all latitudes of the New World, from the tropics to the frozen regions of the north. Great varieties, however, exist in the shade of the red or copper[217] color of the Indians. There are two extremes of complexion among mankind—those of the northern European and the African negro; between these there is a series of shades, that of the American Indian being about midway. The structure of the New World, and the circumstances of its inhabitants, may account for the generally equal color of their skin. The western Indian never becomes black, even when dwelling directly under the equator. He lives among stupendous mountain ranges, where cool breezes from the snowy heights sweep through the valleys and over the plains below. The vast rivers springing from under those lofty peaks inundate a great extent of country, and turn it into swamps, whence perpetual exhalations arise and lower the temperature. There are no fiery deserts to heat the passing wind and reflect the rays of the sun; a continual forest, with luxuriant foliage, and a dense underwood, spreads a pleasant shade over the surface of the earth. America, under the same latitudes, especially on the eastern coast, is every where colder than the Old World. The nearest approach to a black complexion is seen in the people of Brazil, a country comparatively low, and immediately under the equator. The inhabitants of the lofty Mexican table-land are also very dark, and on those arid plains the sun pours down its scorching rays upon a surface almost devoid of sheltering vegetation.
The habits of savage life, and the constant exposure to the elements, seem sufficient to cause a dark tint upon the human skin even in the temperate regions of America, where the cold is far greater than in the same latitude in Europe. The inhabitants of those immense countries are badly clothed, imperfectly defended against the weather, miserably housed; wandering in war or in the chase, exposed for weeks at a time to the mercy of the elements, they soon darken into the indelible red or copper color of their race. On the northwest coasts, about latitude 50°, in Nootka Sound, and a number of other smaller bays, dwell a people more numerous and better provided with food and shelter than their eastern neighbors. They are free from a great part of the toils and hardships of the hunter, and from the vicissitudes of the season. When cleansed from their filthy and fantastic painting, it appears that their complexion and features resemble those of the European.[218]
Modern discoveries have to a great extent dispelled the mystery of the Indian origin, and proved the fallacy of the numerous and ingenious theories formerly advanced with so much pertinacity and zeal. Since the northwest coasts of America and the northeast of Asia have been explored, little difficulty remains on this subject. The two continents approach so nearly in that direction that they are almost within sight of each other, and small boats can safely pass the narrow strait. Ten degrees further south, the Aleutian and Fox Islands[219] form a continuous chain between Kamtschatka and the peninsula of Alaska, in such a manner as to leave the passage across a matter of no difficulty. The rude and hardy Tschutchi, inhabiting the northeast of Asia, frequently sail from one continent to the other.[220] From the remotest antiquity, this ignorant people possessed the wonderful secret of the existence of a world hidden from the wisest and most adventurous of civilized nations. They were unconscious of the value of their vast discovery; they passed over a stormy strait from one frozen shore to another, as stern and desolate as that they had left behind, and knew not that they had crossed one of the great boundaries of earth. When they first entered upon the wilderness of America, probably the most adventurous pushed down toward the genial regions of the south, and so through the long ages of the past the stream of population flowed slowly on, wave by wave, to the remotest limits of the east and south. The Indians resemble the people of northeastern Asia in form and feature more than any other of the human race. Their population is most dense along the districts nearest to Asia; and among the Mexicans, whose records of the past deserve credence, there is a constant tradition that their Aztec and Toultec chiefs came from the northwest. Every where but to the north, America is surrounded with a vast ocean unbroken by any chain of islands that could connect it with the Old World. Most probably no living man ever crossed this immense barrier before the time of Columbus. It is certain that in no part of America have any authentic traces been found of European civilization; the civilization of America, such as it was, arose, as it flourished, in the fertile plains of Mexico[221] and in the delightful valleys of Peru;[222] there, where the bounty of nature supplied an abundance of the necessaries of life, the population rapidly multiplied, and
