There is found in this desert a kind of ant of great size - bigger than a fox, though not so big as a dog. Some specimens which were caught there are kept at the palace of the Persian king. These creatures as they burrow underground throw up the sand in heaps, just as our own ants throw up the earth, and they are very like ours in shape. The sand has a rich content of gold, and this it is what the Indians are after when they make their expeditions into the desert. Each man harnesses three camels abreast, a female, on which he rides, in the middle, and a male on each side in a leading-rein, and takes care that the female is one who has as recently as possible dropped her young. Their camels are as fast as horses, and much more powerful carriers. There is no need for me to describe the camel, for the Greeks are familiar with what it looks like; one thing, however, I will mention, which will be news to them: the camel in its hind legs has four thighs and four knees, and its genitals point backwards towards its tail. That, then, is how these Indians equip themselves for the expedition, and they plan their timetable so as actually to get their hands on the gold during the hottest part of the day, when the heat will have driven the ants underground. In this part of the world the sun is not, as it is elsewhere, hottest at noon, but in the morning: from dawn, that is, until closing-time in the market. During this part of the day the heat is much fiercer than it is at noon in Greece, and the natives are said to soak themselves in water to make it endurable. At midday the heat diminishes and is much the same here as elsewhere, and, as the afternoon goes on, it becomes about equal to what one finds in other countries in the early morning. Towards evening it grows cooler and cooler, until at sunset it is really cold.

Literally Lost 63: The extract was from one of Edward Lear's letters. The action took place in Mount Athos in Greece. The winner is Jean Caws of Hertford.
