Others however of the Indians are on the borders of the city of Caspatyros and the country of Pactyïke, dwelling towards the North 91 of the other Indians; and they have a manner of living nearly the same as that of the Bactrians: these are the most warlike of the Indians, and these are they who make expeditions for the gold. For in the parts where they live it is desert on account of the sand; and in this desert and sandy tract are produced ants, which are in size smaller than dogs but larger than foxes, for 92 there are some of them kept at the residence of the king of Persia, which are caught here. These ants then make their dwelling under ground and carry up the sand just in the same manner as the ants found in the land of the Hellenes, which they themselves 93 also very much resemble in form; and the sand which is brought up contains gold. To obtain this sand the Indians make expeditions into the desert, each one having yoked together three camels, placing a female in the middle and a male like a trace-horse to draw by each side. On this female he mounts himself, having arranged carefully that she shall be taken to be yoked from young ones, the more lately born the better. For their female camels are not inferior to horses in speed, and moreover they are much more capable of bearing weights.
103. As to the form of the camel, I do not here describe it, since the Hellenes for whom I write are already acquainted with it, but I shall tell that which is not commonly known about it, which is this:—the camel has in the hind legs four thighs and four knees, 94 and its organs of generation are between the hind legs, turned towards the tail.
104. The Indians, I say, ride out to get the gold in the manner and with the kind of yoking which I have described, making calculations so that they may be engaged in carrying it off at the time when the greatest heat prevails; for the heat causes the ants to disappear underground. Now among these nations the sun is hottest in the morning hours, not at midday as with others, but from sunrise to the time of closing the market: and during this time it produces much greater heat than at midday in Hellas, so that it is said that then they drench themselves with water. Midday however has about equal degree of heat with the Indians as with other men, while after midday their sun becomes like the morning sun with other men, and after this, as it goes further away, it produces still greater coolness, until at last at sunset it makes the air very cool indeed.
105. When the Indians have come to the place with bags, they fill them with the sand and ride away back as quickly as they can, for forthwith the ants, perceiving, as the Persians allege, by the smell, begin to pursue them: and this animal, they say, is superior to every other creature in swiftness, so that unless the Indians got a start in their course, while the ants were gathering together, not one of them would escape. So then the male camels, for they are inferior in speed of running to the females, if they drag behind are even let loose 95 from the side of the female, one after the other; 96 the females however, remembering the young which they left behind, do not show any slackness in their course. 97 Thus it is that the Indians get most part of the gold, as the Persians say; there is however other gold also in their land obtained by digging, but in smaller quantities.
