The roads of Hong-Kong and the Bay of Victoria form an excellent anchorage, having deep water very near the shore, and only one small shoal having sixteen feet water upon it. There are, however, two disadvantages under which it labours: it is exposed to the full fury of the typhoons whenever they occur; and the high mountains of Hong-Kong intercept the genial breezes of the south-west monsoon during the hot season, when a movement in the atmosphere is most necessary, not only to moderate the sultry summer heat of a tropical climate, but to dissipate the unhealthy vapours which are generated after the heavy rains which occur, particularly during the night, at that season. In other respects, the lake-like appearance of the harbour is beautiful; it forms a sort of basin, lying between the mountains of Hong-Kong and the mountains of the mainland opposite. For this reason, however, the rains which fall are sometimes excessively heavy: the dark, threatening clouds seem banded across from one side to the other, pouring down their waters in torrents upon the basin between them. The mountain sides of Hong-Kong, steep though they are, occasionally appear almost covered with a sheet of moving water, so torrent-like do the streams pour down their declivities. To this succeeds the burning, tropical sun of July, with a sort of death-like stillness in the atmosphere, which, little influenced as it is on that side of the island by the south-west monsoon, cannot fail, if it last long without any change, to produce fever and sickness. Almost all tropical countries are occasionally subject to these visitations; but, as a proof that Hong-Kong is not always exposed to them, I may be permitted to mention that a gentleman who was once at anchor there, in company with a fleet of full fifty sail of merchant ships during a period of nine months, including the whole summer season, declared that he observed _no prevailing fever or sickness of any kind_. The extremely barren appearance of nearly all the islands at the mouth of the Canton River, the deep and rugged furrows which seem to plough up their mountain sides, the exposed, rocky surface of their summits, and the absence of soil, except in sheltered spots or hollows, seem at once to point out that they are situated within the influence of hurricanes and tropical rains. In this respect, the contrast between this part of China and the Chusan Islands to the northward, is very remarkable. The latter look as rich and inviting, both near and at a distance, as the former appear inhospitable and barren. In the one case, there is an industrious and thriving population, who contrive to cultivate the surface of the mountains, frequently to their very summits, with the greatest care and nicety; in the other case, there is a hardy and adventurous population of fishermen, smugglers, and pirates; the unwilling soil is only cultivated in scattered patches, and the villages are few, and comparatively of mean appearance.
