            "description": " \"Earlier steppe people had exchanged some of their horses for Chinese silk, but the scale of the Sino- Uighur trade was unusually large. It reached impressive proportions about 760 and became one of the most important aspects of their mutual relations. A Chinese historian explains its development as follows: The Uighurs, taking advantage of their service to China [during the An Lu-shan rebellion], frequently used to send embassies with horses to trade at an agreed price for silken fabrics. Usually they came every year, trading one horse for forty pieces of silk. Every time they came they brought several tens of thousands of horses [. . .] The barbarians acquired silk insatiably and we were given useless horses. The court found it extremely galling.44 This was a forced trade, of far greater value to the Uighurs than to the Chinese, and continued throughout the period of the Uighur empire. Most of the vast quantity of silk involved could be re-exported to other countries or function as a form of currency. But some of it was possibly used among the urban rich, who were becoming accustomed to a softer life.\" §REF§(Mackerras 1990, 338)§REF§"

Fishing was carried out from coastal farms, and also from seasonal fishing stations when fish, especially cod, came ashore. Cereal crops were grown in Iceland in the Middle Ages, mainly in the south, but animal husbandry (cattle and sheep) was the mainstay. Both provided meat, and milk for cheese and skyr (milk curd), and the sheep's wool was woven into cloth which was Iceland's principal export commodity until the 14th century [...]. The Icelandic way of life is well illustrated by the units of value used: alin vadmáls (an ell, about 50cm, of woollen cloth), kúgildi (the value of a cow), equivalent to 120 ells, and subsequently fiskur (fish), equivalent to half an ell.' §REF§Karlsson, Gunnar 2000. \"A Brief History of Iceland\", 12p§REF§ Both ecclesiastical and secular authorities collected taxes from commoners, but the relevant units (articles versus currency) is unclear from the descriptions: 'With like energy he preached the crusade to the Holy Land which had been urged at the Council of Bergen. People were prevailed upon to pay an extra tax of one öln vadmál year for the period of six years to defray the expenses of the undertaking.

[...] The king's officers also travelled about collecting the royal revenues with greater severity that had hitherto been customary. They reproved the people for appealing to the bishop, and in some cases forbade them to pay as large church dues as the bishop had demanded.' §REF§Gjerset, Knut [1924]. \"History of Iceland\", 220§REF§"

Visiting the coast, these inlanders will even take calabashes and bring them home full of sea-water. The only means of obtaining it locally is by burning certain leaves and the husks of coco-nut or Tauga nuts.
