" You would never thereby learn that Africans first domesticated the sheep, goat, and cow, developed the idea of trial by jury, produced the first stringed instruments, and gave the world its greatest boon in the discovery of iron. You would never know that prior to the Mohammedan invasion about 1000 A.D. these natives in the heart of Africa had developed powerful kingdoms which were later organized as the Songhay Empire on the order of that of the Romans and boasting of similar grandeur.
