After eight days farther travel to the east, we come to the district of Egrigaia[4], which is still in the kingdom of Tangut, and subject to the great khan; it contains many cities and castles, Calacia being the principal city, which is inhabited by idolaters, though the Nestorian Christians have three churches.  In this city, excellent camblets are manufactured from, white wool, and the hair of camels[5] which are exported by the merchants to all parts of the world, and particularly to Kathay.

East from this province of Egrigaia is that of Tandach[6], in which there are many cities and castles.  The king of this nation is called George, who is a Christian and a priest[7], and most of the people also are Christians; he is descended of Prester John, formerly mentioned under the name of Umcan, from whom he is the fourth in descent, and he pays tribute to the great khan; and ever since the battle in which Umcan was slain by Zingis, the great khans have given their daughters in marriage to the kings of this country, who do not possess all the dominions which were formerly subject to Prester John.  There is a mixed race in this country, called Argons, descended of idolaters and Mahometans, who are the handsomest people in these parts, and are most ingenious manufacturers and cunning merchants.  This province was the chief residence of Prester John, and there are two neighbouring districts, called Ung and Mongol by the natives, which the people of Europe call Gog and Magog.

Travelling eastwards for seven days towards Kathay, there are many cities, inhabited by idolaters, Mahometans, and Nestorians, who live by commerce and manufactures, and who make stuffs wrought with gold and flowers, and other silken stuffs of all kinds, and colours like those made among us, and also woollen cloths of various kinds.  One of these towns is Sindicin, or Sindacui, where very excellent arms of all kinds fit for war are manufactured.  In the mountains of this province, called Idifa, or Ydifu, there are great mines of silver.

Three days journey from Sindicin stands another city, named Iangamur[8], which signifies the White Lake.  Near this place, the khan has a palace, in which he takes great delight, as he has fine gardens, with many lakes and rivers, and multitudes of swans, and the adjacent plains abound in cranes, pheasants, partridges, and other game.  There are five sorts of cranes here, some of which have black wings, others are white and bright; their feathers being ornamented with eyes like those of a peacock, but of a golden colour, with beautiful black and white necks; a third kind is not unlike our own, in size and appearance; the fourth kind is very small and beautiful, variegated with red and blue; the fifth is very large, and of a grey colour, with black and red heads.  In a valley near this city, there are astonishing numbers of quails and partridges, for the maintenance of which the khan causes millet and other seeds to be sown, that they
