Once again, if millennial contact and intermingling of such near affinities as Teuton and Alpine Kelt have not availed to efface their distinguishing features, either of body or of mind--if the wonted ancestral fires still live in the remote descendants--how can we hope for aught else from the mixture of European and African? Will not the slumberous apathy in which the Dark Continent broods away its æons surely fall upon the people that drink its blood into their own veins? Not to anticipate such a result is to scorn analogy, to despise science, to defy history. We now come to the second question: _Will intermingling with inferiors really lower the superior stock?_ It seems very hard to believe that any sober-minded man can long hesitate to answer, Yes. Does any breeder of horses or cattle or dogs or pigeons, or any cultivator of grains or flowers, or any student of heredity in either plants or animals, entertain any doubt whatever? We trow not. We need not, however, appeal to general principles, or to common sense, or to universal observation of the lower planes of life. The mingling of races is no new thing on our planet; it has been widely diffused, and the results are matters of record. We shall content ourselves with citing a single authority, than whom there is none higher--whom not even the most suspicious will suspect of Southern ignorance and prejudice. We allude to the distinguished author of "The American Commonwealth," and the "Assimilation of Races in the United States."
