We passed through the streight of Formosa without seeing any part of the main land of China, or of the island from whence the streight derives its name, except a high point towards the northern extremity. The weather, indeed, during three successive days, the 25th, 26th, and 27th July was so dark and gloomy, that the eye could scarcely discern the largest objects at the distance of a mile, yet the thermometer was from 80° to 83° the greater part of these days. A heavy and almost incessant fall of rain was accompanied with violent squalls of wind, and frequent bursts of thunder and flashes of lightning; which, with the cross and confused swell in the sea, made the passage not only uncomfortably irksome, but also extremely dangerous, on account of the many islands interspersed in almost every part of the strait. On the evening of the 25th the sun set in a bank of fog, which made the whole western side of the horizon look like a blaze of fire, and the barometer was observed to have fallen near one third of an inch, which, in these latitudes and at sea, is considered as a certain indication of a change of weather. There were on board some Chinese fishermen who had been driven out to sea in one of the East India company's ships, which we met with in the straits of Sunda. These men assured us that the appearance of the heavens prognosticated one of those tremendous gales of wind which are well known to Europeans by the name of _Ty-phoon_ and which some ingenious and learned men have supposed to be the same as the Typhon of the Egyptians or τυφων of the Greeks. The Chinese, however have made use of no mythological allusion in naming this hurricane. They call it _Ta-fung_ which literally signifies _a great wind_. The wind was certainly high the whole of the night and the following day, the thunder and lightning dreadful, and the variable squalls and rain frequent and heavy; the depth of the sea from 25 to 30 fathoms. The charts, however, of this passage into the Yellow Sea, constructed by Europeans when the Chinese permitted foreign nations to trade to _Chu-san_, are considered as sufficiently exact for skilful navigators to avoid the dangerous rocks and islands. By the help of these charts our squadron ventured to stand through the still more intricate and narrow passages of the Chu-san Archipelago, where, in the contracted space of about eight hundred square leagues, the surface of the sea is studded with a cluster, consisting, nearly, of four hundred distinct islands.
