Alexander's desire was to extend his conquests to the Ganges, but his soldiers began to murmur because of the length and hardness of their campaigns, and he reluctantly gave up the undertaking. To secure the conquests already made, he founded, at different points in the valley of the Indus, Greek towns and colonies. One of these he named Alexandria, after himself; another Bucephala, in memory of his favorite steed; and still another Nicæa, for his victories. The modern museum at Lahore contains many relics of Greek art, dug up on the site of these Macedonian cities and camps. Alexander's return route lay through the ancient Gedrosia, now Beluchistan, a region frightful with burning deserts, amidst which his soldiers endured almost incredible privations and sufferings. After a trying and calamitous march of over two months, Alexander, with the survivors of his army, reached Carmania. Here, to his unbounded joy, he was joined by Nearchus, the trusted admiral of his fleet, whom he had ordered to explore the sea between the Indus and the Euphrates. To appropriately celebrate his conquests and discoveries, Alexander instituted a series of religious festivals, amidst which his soldiers forgot the dangers of their numberless battles and the hardships of their unparalleled marches, which had put to the test every power of human endurance. And well might these veterans glory in their achievements. In a few years they had conquered half the world, and changed the whole course of history. PLANS AND DEATH OF ALEXANDER.--As the capital of his vast empire, which now stretched from the Ionian Sea to the Indus, Alexander chose the ancient Babylon, upon the Euphrates. His designs were to push his conquests as far to the west as he had extended them to the east. Arabia, Carthage, Italy, and Spain were to be added to his already vast domains. Indeed, the plans of Alexander embraced nothing less than the union and Hellenizing of the world. Not only were the peoples of Asia and Europe to be blended by means of colonies, but even the floras of the two continents were to be intermingled by the transplanting of fruits and trees from one continent to the other. Common laws and customs, a common language and a common religion, were to unite the world into one great family. Intermarriages were to blend the races. Alexander himself married a daughter of Darius III., and also one of Artaxerxes Ochus; and to ten thousand of his soldiers, whom he encouraged to take Asiatic wives, he gave magnificent gifts.
