On the other hand the settled folk had their textiles and their pottery and made many desirable things. It was inevitable that as the two sorts of life, the agricultural and the nomadic differentiated, a certain amount of looting and trading should develop between the two. In Sumeria particularly which had deserts and seasonal country on either hand it must have been usual to have the nomads camping close to the cultivated fields, trading and stealing and perhaps tinkering, as gipsies do to this day. (But hens they would not steal, because the domestic fowl—an Indian jungle fowl originally—was not domesticated by man until about 1000 B.C. They would bring precious stones and things of metal and leather. If they were hunters they would bring skins. They would get in exchange pottery and beads and glass, garments and suchlike manufactured things.

See, I was so bewildered. That is why I posted the thread here.
