population who took on Chinese surnames and customs. The town of Canton itself, although parts were surrounded by walls, continued to be inhabited by a large matshed population. It was full of Arabs, Indians and Persians who were allowed to have their own administration and laws and to settle in the place without hindrance. Here is a quotation from the famous Arab book known as the Chain of Chronicles which is an account of the trade with China in the ninth century compiled by the Zaid Hassan of Siraf in Arabia.

Since this event preceded a decline in the trade with the west from Canton it is as well to try and form a picture of it up to this period.
The boats used were larger than any of the native craft that are now seen on the Chinese coast. As early as 413 Fa Hsien the Buddhist pilgrim returned from Java on a boat which carried over 200 people. It drifted, he says, at the mercy of the wind without taking any particular course and "only by observing the sun, moon and stars was it possible to go forward." Fa Hsien's ship was set for Canton but was blown out of its course as far as Shantung where they landed without knowing in the least where they were. In spite of the difficulty of steering without a compass the trade route was very much helped, as it has always been, by the monsoons which blow from the north in winter and from the south in summer. There is some evidence that tacking was
