ZAYTON, as Martini and Deguignes conjectured, is T’SWAN-CHAU FU, or CHWAN-CHAU FU (written by French scholars _Thsiouan-tchéou-fou_), often called in our charts, etc., _Chinchew_, a famous seaport of Fo-kien about 100 miles in a straight line S.W. by S. of Fu-chau. Klaproth supposes that the name by which it was known to the Arabs and other Westerns was corrupted from an old Chinese name of the city, given in the Imperial Geography, viz. TSEU-T’UNG.[1] _Zaitún_ commended itself to Arabian ears, being the Arabic for an olive-tree (whence Jerusalem is called _Zaitúniyah_); but the corruption (if such it be) must be of very old date, as the city appears to have received its present name in the 7th or 8th century. Abulfeda, whose Geography was terminated in 1321, had heard the real name of Zayton: “_Shanju_” he calls it, “known in our time as Zaitún”; and again: “Zaitún, _i.e._ Shanju, is a haven of China, and, according to the accounts of merchants who have travelled to those parts, is a city of mark. It is situated on a marine estuary which ships enter from the China Sea. The estuary extends fifteen miles, and there is a river at the head of it. According to some who have seen the place, the tide flows. It is half a day from the sea, and the channel by which ships come up from the sea is of fresh water. It is smaller in size than Hamath, and has the remains of a wall which was destroyed by the Tartars. The people drink water from the channel, and also from wells.”
