Since the questions connected with the opium-trade have been brought so prominently forward, it has been maintained by some, that the "outer waters" ought not properly to be considered within Chinese jurisdiction. But this position would hardly seem to be tenable; and there can be no sound reason for maintaining that these waters should not be considered as much, and _even more_, within their jurisdiction as the sea-coast or river islands of any part of Europe are within the jurisdiction of the country to which they belong, to the distance of a certain number of miles from the land itself. In reality, the little peninsula of Macao on the west, and the island of Lintao (not to be confounded with Lintin) on the east, may be considered as the proper boundaries of the entrance to the Canton River. These points are about fifteen to twenty miles apart, while between them lie several small islands, through which are the two principal navigable passages (the western and the Lintao passages) into the river itself. But the island of Lintao, called Tyho by the Chinese, is a long, narrow, mountainous piece of land, broken up into numerous bays and projecting points, stretching from south-west to north-east, separated at the latter extremity from the mainland only about the distance of a mile. The passage and anchorage between them is called Capsingmoon, and is made use of occasionally even by large vessels, which pass towards the river or across from Macao towards the island of Hong-Kong, which lies off the mainland at about five or six miles to the eastward of Lintao.[13] The anchorage of Tongkoo Bay, towards which the Nemesis was to proceed to rejoin the fleet, and which is also known by the name of Urmston's Harbour, from having been recommended by Sir James Urmston, formerly President of the Company's factory at Canton, is situated about six miles due north from Lintao, between the little islands called Tongkoo and Sowchow, near the mainland, as you proceed upwards within the outer waters of the Canton River, along its eastern shores. It was here that the fleet anchored in 1823, in consequence of some discussions with the Chinese, arising out of the affair of the Topaze frigate, which occurred in the preceding year.[14] About five miles distant from Tongkoo Bay, more towards the centre of the river, and a little to the northward, is the small island of Lintin, terminating in a very remarkable, high, conical peak, which is a guide to all vessels passing up or down. It has become famous as a place of rendezvous for the opium vessels, particularly within the last few years; and a merchant brig, bearing its name, has been recently sold to the Chinese as a man-of-war, though old and not very serviceable. This island must not be confounded with that of Lintao, before alluded to, and from which it is about eight or nine miles distant.
