12. It is probable that those who sailed in the expedition greatly exaggerated many circumstances; yet their statements prove the sufferings to which they were exposed, and that their apprehensions were greater than the real danger. That which alarmed them the most was the magnitude of the whales, which occasioned great commotion in the sea from their numbers; their blowing was attended with so great a darkness, that the sailors could not see where they stood. But when the pilots informed the sailors, who were terrified at the sight and ignorant of the cause, that they were animals which might easily be driven away by the sound of a trumpet, and by loud noises, Nearchus impelled the vessels with violence in the direction of the impediment, and at the same time frightened the animals with the sound of trumpets. The whales dived, and again rose at the prow of the vessels, so as to give the appearance of a naval combat; but they soon made off. 13. Those who now sail to India speak of the size of these animals and their mode of appearance, but as coming neither in bodies nor frequently, yet as repulsed by shouts and by the sound of trumpets. They affirm that they do not approach the land, but that the bones of those which die, bared of flesh, are readily thrown up by the waves, and supply the Ichthyophagi with the above-mentioned material for the construction of their cabins. According to Nearchus, the size of these animals is three and twenty orguiæ in length.[438] [CAS. 726] Nearchus says that he proved the confident belief of the sailors in the existence of an island situated in the passage, and destructive to those who anchored near it, to be false. A bark in its course, when it came opposite to this island, was never afterwards seen, and some men who were sent in search did not venture to disembark upon the island, but shouted and called to the crew, when, receiving no answer, they returned. But as all imputed this disappearance to the island, Nearchus said that he himself sailed to it, went ashore, disembarked with a part of his crew, and went round it. But not discovering any trace of those of whom he was in search, he abandoned the attempt, and informed his men that no fault was to be imputed to the island (for otherwise destruction would have come upon himself and those who disembarked with him), but that some other cause (and innumerable others were possible) might have occasioned the loss of the vessel. 14. Carmania is the last portion of the sea-coast which begins from the Indus. Its first promontory projects towards the south into the Great Sea.[439] After it has formed the mouth of the Persian Gulf towards the promontory, which is in sight, of Arabia Felix, it bends towards the Persian Gulf, and is continued till it touches Persia.
