Much has been made of the supposed smaller brain of the Negro race; but this is as yet an unproved assumption, based on the uncritical measurement of less than a thousand Negro brains as compared with eleven thousand or more European brains. Even if future measurement prove the average Negro brain lighter, the vast majority of Negro brain weights fall within the same limits as the whites; and finally, "neither size nor weight of the brain seems to be of importance" as an index of mental capacity. We may, therefore, say with Ratzel, "There is only one species of man. The variations are numerous, but do not go deep."[39]
To this we may add the word of the Secretary of the First Races Congress: "We are, then, under the necessity of concluding that an impartial investigator would be inclined to look upon the various important peoples of the world as to all intents and purposes essentially equal in intellect, enterprise, morality, and physique."[40]
If these conclusions are true, we should expect to see in Africa the human drama play itself out much as in other lands, and such has actually been the fact. At the same time we must expect peculiarities arising from the physiography of the land—its climate, its rainfall, its deserts, and the peculiar inaccessibility of the coast.
Three principal zones of habitation appear: first, the steppes and deserts around the Sahara in the north and the Kalahari desert in the south; secondly, the grassy highlands bordering the Great Lakes and connecting these two regions; thirdly, the forests and rivers of Central and West Africa. In the deserts are the nomads, and the Pygmies are in the forest fastnesses. Herdsmen and their cattle cover the steppes and highlands, save where the tsetse fly prevents. In the open forests and grassy highlands are the agriculturists.
Among the forest farmers the village is the center of life, while in the open steppes political life tends to spread into larger political units. Political integration is, however, hindered by an ease of internal communication almost as great as the difficulty of reaching outer worlds beyond the continent. The narrow Nile valley alone presented physical barriers formidable enough to keep back the invading barbarians of the south, and even then with difficulty. Elsewhere communication was all too easy. For a while the Congo forests fended away the restless, but this only temporarily.
On the whole Africa from the Sahara to the Cape offered no great physical barrier to the invader, and we continually have whirlwinds of invading hosts rushing now southward, now northward, from the interior to the coast and from the coast inland, and hurling their force against states, kingdoms, and cities. Some resisted for generations, some for centuries, some but a few years. It is, then, this sudden change and the fear of it that marks African culture, particularly in its political aspects, and which makes it so difficult to trace this changing past. Nevertheless beneath all change rests the strong substructure of custom, religion, industry, and art well worth the attention of students.
Starting with agriculture, we learn that "among all the great groups of the 'natural' races, the Negroes are the best and keenest tillers of the ground. A minority despise agriculture and breed cattle; many combine both occupations. Among the genuine tillers the whole life of the family is taken up in agriculture, and hence the months are by preference called after the operations which they demand. Constant clearings change forests to fields, and the ground is manured with the ashes of the burnt thicket. In the middle of the fields rise the light watch-towers, from which a watchman scares grain-eating birds and other thieves. An African cultivated landscape is incomplete without barns. The rapidity with which, when newly imported, the most various forms of cultivation spread in Africa says much for the attention which is devoted to this branch of economy. Industries, again, which may be called agricultural, like the preparation of meal from millet and other crops, also from cassava, the fabrication of fermented drinks from grain, or the manufacture of cotton, are widely known and sedulously fostered."[41]
Bücher reminds us of the deep impression made upon travelers when they sight suddenly the well-attended fields of the natives on emerging from the primeval forests. "In the more thickly populated parts of Africa these fields often stretch for many a mile, and the assiduous care of the Negro women shines in all the brighter light when we consider the insecurity of life, the constant feuds and pillages, in which no one knows whether he will in the end be able to harvest what he has sown. Livingstone gives somewhere a graphic description of the devastations wrought by slave hunts; the people were lying about slain, the dwellings were demolished; in the fields, however, the grain was ripening and there was none to harvest it."[42]
Sheep, goat, and chickens are domestic animals all over Africa, and Von Franzius considers Africa the home of the house cattle and the Negro as the original tamer. Northeastern Africa especially is noted for agriculture, cattle raising, and fruit culture. In the eastern Sudan, and among the great Bantu tribes extending from the Sudan down toward the south, cattle are evidences of wealth; one tribe, for instance, having so many oxen that each village had ten or twelve thousand head. Lenz (1884), Bouet-Williaumez (1848), Hecquard (1854), Bosman (1805), and Baker (1868) all bear witness to this, and Schweinfurth (1878) tells us of great cattle parks with two to three thousand head and of numerous agricultural and cattle-raising tribes. Von der Decken (1859-61) described the paradise of the dwellers about Kilimanjaro—the bananas, fruit, beans and peas, cattle raising with stall feed, the fertilizing of the fields, and irrigation. The Negroid Gallas have seven or eight cattle to each inhabitant. Livingstone bears witness to the busy cattle raising of the Bantus and Kaffirs. Hulub (1881) and Chapman (1868) tell of agriculture and fruit raising in South Africa. Shutt (1884) found the tribes in the southwestern basin of the Congo with sheep, swine, goats, and cattle. On this agricultural and cattle-raising economic foundation has arisen the organized industry of the artisan, the trader, and the manufacturer.
While the Pygmies, still living in the age of wood, make no iron or stone implements, they seem to know how to make bark cloth and fiber baskets and simple outfits for hunting and fishing. Among the Bushmen the art of making weapons and working in hides is quite common. The Hottentots are further advanced in the industrial arts, being well versed in the manufacture of clothing, weapons, and utensils. In the dressing of skins and furs, as well as in the plaiting of cords and the weaving of mats, we find evidences of their workmanship. In addition they are good workers in iron and copper, using the sheepskin bellows for this purpose. The Ashantis of the Gold Coast know how to make "cotton fabrics, turn and glaze earthenware, forge iron, fabricate instruments and arms, embroider rugs and carpets, and set gold and precious stones."[43] Among the people of the banana zone we find rough basket work, coarse pottery, grass cloth, and spoons made of wood and ivory. The people of the millet zone, because of uncertain agricultural resources, quite generally turn to manufacturing. Charcoal is prepared by the smiths, iron is smelted, and numerous implements are manufactured. Among them we find axes, hatchets, hoes, knives, nails, scythes, and other hardware. Cloaks, shoes, sandals, shields, and water and oil vessels are made from leather which the natives have dressed. Soap is manufactured in the Bautschi district, glass is made, formed, and colored by the people of Nupeland, and in almost every city cotton is spun and woven and dyed. Barth tells us that the weaving of cotton was known in the Sudan as early as the eleventh century. There is also extensive manufacture of wooden ware, tools, implements, and utensils.
