ANTIQUITY OF MAN.--We do not know when man first came into possession of the earth. We only know that, in ages vastly remote, when both the climate and the outline of Europe were very different from what they are at present, man lived on that continent with animals now extinct; and that as early as 4000 or 3000 B.C.,--when the curtain first rises on the stage of history,--in some favored regions, as in the Valley of the Nile, there were nations and civilizations already venerable with age, and possessing languages, arts, and institutions that bear evidence of slow growth through very long periods of time before written history begins. [Footnote: The investigation and study of this vast background of human life is left to such sciences as _Ethnology, Comparative Philology_, and _Prehistoric Archeology_.] THE RACES OF MANKIND.--Distinctions in form, color, and physiognomy divide the human species into three chief types, or races, known as the Black (Ethiopian, or Negro), the Yellow (Turanian, or Mongolian), and the White (Caucasian). But we must not suppose each of these three types to be sharply marked off from the others; they shade into one another by insensible gradations. There has been no perceptible change in the great types during historic times. The paintings upon the oldest Egyptian monuments show us that at the dawn of history, about five or six thousand years ago, the principal races were as distinctly marked as now, each bearing its racial badge of color and physiognomy. As early as the times of Jeremiah, the permanency of physical characteristics had passed into the proverb, "Can the Ethiopian change his skin?" Of all the races, the White, or Caucasian, exhibits by far the most perfect type, physically, intellectually, and morally. [Illustration: NEGRO CAPTIVES, From the Monuments of Thebes. (Illustrating the permanence of race characteristics.)] THE BLACK RACE.--Africa is the home of the peoples of the Black Race, but we find them on all the other continents, whither they have been carried as slaves by the stronger races; for since time immemorial they have been "hewers of wood and drawers of water" for their more favored brethren. THE YELLOW, OR TURANIAN RACE.--The term Turanian is very loosely applied by the historian to many and widely separated families and peoples. In its broadest application it is made to include the Chinese and other more or less closely allied peoples of Eastern Asia; the Ottoman Turks, the Hungarians, the Finns, the Lapps, and the Basques, in Europe; and (by some) the Esquimaux and American Indians.
