In tracing along the history of mankind, there is no period which we can select when mankind have not seemed as busy in destroying their own, and the happiness of others, as the lower animals are in seeking their appropriate enjoyments. At one time we behold Xerxes pouring forth all Asia upon Europe, where three million beings were brought to be slaughtered by the Greeks. At another time the Greeks, headed by Alexander, return upon Asia, and spread over most of the known world, pillaging, burning, and slaughtering. Then we behold Alaric, at the head of barbarous hordes, desolating all the Roman empire, and destroying the monuments of taste, science, and the arts. Then we see Tamerlane rushing forth, overrunning Persia, India, and other parts of Asia, carrying carnage and the most desolating cruelty in his course, so that it is recorded that he would cause thousands of his prisoners to be pounded in mortars with bricks to form into walls. From Europe we behold _six millions_ of Crusaders rush forth upon the plains of Asia, with rapine, and famine, and outrage attending their course. Then come forth from Eastern Asia the myrmidons of Genghis Khan, ravaging fifteen millions of square miles, beheading 100,000 prisoners at one time, shaking the whole earth with terror, and exterminating fourteen millions of their fellow-men. Then from the northern forests are seen swarming forth the Goths and Vandals, sweeping over Europe and Asia, and bearing away every vestige of arts, civilization, comfort, and peace. At another time we see the professed head of the Christian Church slaughtering the pious and inoffensive Albigenses, sending horror into their peaceful villages, and torturing thousands of inoffensive victims.
