power, a portion of the soft sandy lagoon, which is gradually invading and narrowing the available anchorage of the harbour, might soon be added to the now limited accommodation for ship- ping; while the bar at the mouth of the port might no less easily be removed. As the case now stands, with wind and tide favourable, a barque drawing twelve feet of water can find her way through the rocky entrance. Rapid physical changes have taken place within a recent period on this western side of Formosa, as I shall be able to demonstrate conclusively when we get to a point further north. It struck me, however, that the natural formation of the harbour of Takow belongs to a modern date. Thus, when the Dutch occupied the island, a con- siderable river existed at the southern extremity, and the channel, now nearly dry, is still known as "Ang-mang-kang," or estuary of the red-haired race. The combined action of the sea silting up debris on the one side, and of the river on the other, to- gether with the growth of a crescent-shaped coral reef, has formed a natural barrier several miles in extent, now covered with a belt of most luxuriant tropical trees. This bar is joined at its northern extremity by a ridge of igneous rocks; and it is in this ridge that the break or flaw occurs which forms the mouth of the harbour. Much of the six or seven miles enclosed by this natural wall, consists of a shallow lagoon with a bottom of extremely soft mud. It is only towards the northern end that a depth of water is obtained sufficient for ships trading to the island.
Owing to the disturbed state of the country I deferred my visit to the aboriginal tribes of the south, and went with Dr. Maxwell to see Tai-wan-fu, the capital, twenty-five miles further north on the coast. Starting at daylight in the "Formosa," we reached the outer roads at 8 o'clock. It is singular to observe
