Alexander's losses were principally from men slain in battle; from this, I take it that Alexander knew a deal of sanitary science, and had a knowledge of practical mathematics, in order to systematize that mob of restless, turbulent helots. We hear of Aristotle cautioning him that safety lies in keeping his men busy--they must not have too much time to think, otherwise mutiny is to be feared. Still, they must not be over-worked, or they will be in no condition to fight when the eventful time occurs. And we are amazed to see this: "Do not let your men drink out of stagnant pools--Athenians, city-born, know no better. And when you carry water on the desert marches, it should be first boiled to prevent its getting sour." Concerning the Jews, Alexander writes to his teacher and says, "They are apt to be in sullen rebellion against their governors, receiving orders only from their high priests, and this leads to severe measures, which are construed as persecution"; all of which might have been written yesterday by the Czar in a message to The Hague Convention. Alexander captured the East, and was taken captive by the East. Like the male bee that never lives to tell the tale of its wooing, he succeeded and died. Yet he vitalized all Asia with the seeds of Greek philosophy, turned back the hungry barbaric tide, and made a new map of the Eastern world. He built far more cities than he destroyed. He set Andrew Carnegie an example at Alexandria, such as the world had never up to that time seen. At the entrance to the harbor of the same city he erected a lighthouse, surpassing far the one at Minot's Ledge, or Race Rock. This structure endured for two centuries, and when at last wind and weather had their way, there was no Hopkinson Smith who could erect another. At Thebes, Alexander paid a compliment to letters, by destroying every building in the city except the house of the poet, Pindar. At Corinth, when the great, the wise, the noble, came to pay homage, one great man did not appear. In vain did Alexander look for his card among all those handed in at the door--Diogenes, the Philosopher, oft quoted by Aristotle, was not to be seen. Alexander went out to hunt him up, and found him sunning himself, propped up against the wall in the Public Square, busy doing nothing. The philosopher did not arise to greet the conqueror; he did not even offer a nod of recognition. "I am Alexander--is there not something I can do for you?" modestly asked the descendant of Hercules. "Just stand out from between me and the sun," replied the philosopher, and went on with his meditations. Alexander enjoyed the reply so much that he said to his companions, and afterward wrote to Aristotle, "If I were not Alexander, I would be Diogenes," and thus did strenuosity pay its tribute to self-sufficiency. * * * * *
