At the very mouth of the river they met a formidable obstacle,--a rocky bar over which the waves broke with extreme violence. Through this bar, in its softest parts, they cut a canal one-third of a mile in length, and at high tide passed through it with the fleet. They had hardly reached the open ocean before a heavy gale drove them into an indentation of land protected by an island: to this natural harbor Nearchus gave the name of Alexander. Here he caused a camp to be laid out and entrenched, and remained for twenty-four days, the soldiers subsisting chiefly on shell-fish. When the gale abated they again embarked, meeting with constant adventures and difficulties upon their way. One day they would pass through huge menacing rocks, so near that they touched them with their oars on either side. On another they would be compelled, on landing for water, to ascend for miles into the interior before finding fresh-water sources. A storm caused two galleys and a vessel to founder, the crews of which, however, succeeded in swimming to shore. Nearchus caused his whole army to land at this point, for they needed repose, and his shattered fleet required repairs. He met with Leonatus, whom Alexander had detached from the main body of the army to follow the coasts and keep up a communication with Nearchus. Wheat was also sent to this spot by Alexander for the fleet, and each vessel took a supply sufficient for ten days. Nearchus exchanged such sailors and soldiers as had proved inefficient, for fresh men selected from the division of Leonatus. At this point the narrative becomes strongly tinged with the usual exaggerations of the early navigators. Nearchus asserts that he observed strange phenomena in the heavens. When the sun was in the meridian, he says, no shadow was projected, and the stars which they were accustomed to see above them were now crouching close to the horizon; others, that had never before disappeared from the sky, now rose and set at intervals. The assertion in regard to shadows at noon is evidently a fabrication. Enough was known of astronomy and the motions of the heavenly bodies, in the time of Nearchus, to convince the learned that there must be a point where no shadow would be cast by a body directly beneath the sun at the summer solstice; and Nearchus, with a vanity quite usual in the conquerors and adventurers of those times, chose to assert, and he perhaps believed, that he had seen this singular phenomenon. Two circumstances will show the inaccuracy of his statement. The alleged appearance took place in the middle of the month of November, and twenty-five degrees north of the equator. Even had Nearchus been at this spot in midsummer, he would have seen shadows of very respectable length. Upon the coast of Gedrosia he found a people called Icthyophagi, or Fish-eaters. The mutton here tasted of fish, and Nearchus discovered that the sheep eat fish as well as the inhabitants, for the land yielded no pasturage.
