It is also a curious sight to watch the hundreds of boats and junks getting under weigh at the same moment, all eager to get across to the opposite shore, under shelter of the mainland, as fast as possible, knowing full well that they would be certainly stranded if they remained on the Hong-Kong side. In the high stern of every junk stands a man, who perseveringly beats a large suspended gong with his utmost strength, while the rest of the crew appear quite as intent upon firing off crackers as upon the management of their boat. By this means they hope to awaken their tutelary god, and to induce him to listen to their prayers for succour. The greater part of them take refuge in a bay directly opposite Victoria, from which it is about four miles distant, under the lee of the mountains on that side. Frequently all the threatening appearances which call forth these preparations pass off without producing a typhoon. The flashes of lightning are fearfully quick and brilliant; the peals of thunder are almost deafening; the huge black clouds hang gloomily over the mountains, or are banded across from one side to the other, pouring their waters in torrents upon the basin between them. In this way the storm at length subsides, and the horrors of a typhoon are averted. The actual typhoon is of a very different description; in fact, it differs in no respect from the worst hurricanes which visit the Mauritius or the West Indies. Hong-Kong was visited in this way on the 21st and 26th of July, 1841, and a more severe typhoon than that which took place on the first of those days is, perhaps, never experienced. The theory of these circular storms has been well laid down by Colonel Reid and others; so that in the present day a vessel caught in them at sea would be much less exposed to danger than formerly, provided her captain had made himself master of the well-confirmed theories which have been propounded upon the subject. The sphere of their operation is very limited, neither do they occur every year, but seldom oftener than every three or four years. At Hong-Kong, various ominous appearances were the forerunner of the storm on the occasion alluded to. For some days previously, large black masses of clouds appeared to settle upon the hills on either side: the atmosphere was extremely sultry and oppressive; the most vivid lightning shot incessantly along the dense, threatening clouds, and looked the more brilliant because the phenomena were always most remarkable at night, while during the day the threatening appearances were moderated considerably, and sometimes almost entirely disappeared. The vibrations of the mercury in the barometer were constant and rapid; and, although it occasionally rose, still the improvement was only temporary, and upon the average it continued to fall. A typhoon was, therefore, confidently predicted, and the more so because none had occurred for several years.
