The intellect seemed to become clouded, animation giving place to a sort of lethargy, briskness yielding to indolence. We must necessarily suppose that the development of the negro and white proceeds on different lines. While with the latter the volume of the brain grows with the expansion of the brainpan, in the former the growth of the brain is on the contrary arrested by the premature closing of the cranial sutures and lateral pressure of the frontal bone.
This explanation is reasonable and even probable as a contributing cause; but evidence is lacking on the subject and the arrest or even deterioration in mental development is no doubt very largely due to the fact that after puberty sexual matters take the first place in the negro's life and thoughts. At the same time his environment has not been su;h as would tend to produce in him the restless energy which h,as led to the progress of the white race; and the easy conditions of tropical life and the fertility of the soil have reduced the struggle for existence to a minimum.
But though the mental inferiority of the negro to the white or yellow races is a fact, it has often been exaggerated; the negro is largely the creature of his environment,and it is not fair to judge of his mental capacity by tests taken directly from the environment of the white man, as for instance tests in mental arithmetic; skill in reckoning is necessary to the white race, and it has cultivated this faculty; but it is not necessary to the negro.
On the other hand negroes far surpass white men in acuteness of vision, hearing, sense of direction and topography. A native who has once visited a particular locality will rarely fail to recognize it again. For the rest, the mental constitution of the negro is very similar to that of a child, normally good-natured and cheerful, but subject to sudden fits of emotion and passion during which he is capable of performing acts of singular atrocity, impressionable, vain, but often exhibiting in the capacity of servant a dog-like fidelity which has stood the supreme test.
Given suitable training, the negro is capable of becoming a craftsman of considerable skill, particularly in metal work, carpentry and carving. The bronze castings by the tire perdue process, and the cups and horns of ivory elaborately carved, which were produced by the natives of Guinea after their intercourse with the Portuguese of the i6th century, bear ample witness to this. But the rapid decline and practical evanescence of both industries, when that intercourse was interrupted, shows that the native craftsman was raised for the moment above his normal level by direct foreign inspiration, and was unable to sustain the high quality of his work when that inspiration failed. In speaking of the form or forms of culture found among negro and negroid tribes, the dependence of the native upon his environment must be kept in mind, particularly in Africa, where interchange of customs is continually taking place among neighbors. Thus the forest regions are distinguished by a particular form of culture which differs from that prevailing in the more open country (see AFRICA: Ethnology). But it may be said generally that the negro is first and foremost an agriculturist.
