The Barometer began to fall here as early as the 4th September, and gradients indicated moderate r light winds,-circumstances which are frequently followed by a Typhoon. On the 6th it was pointed out in the China Coast Meteorological Register, that the Barometer was still falling, and espe- Pally S.E. of here. In the afternoon of the 7th, a moderate westerly breeze blew over the Philippine 1-lands, and the Barometer rose in Shanghai and the following day also in Tonquin, those stations bing then covered by the anticyclonic area. On the 8th, the Red Drum was hoisted on the signal The center of the Typhoon was then North of Luzon. Light winds continued to blow here interrupted by calms. The direction whence coming of the lower clouds, which was S.E. on the 4th, backed to N.E. on the 6th, while the upper clouds already on the 5th came up slowly from N.E.. and were found to have backed to North on the 7th, when their velocity was moderate. On the 9th the Barometer had fallen at all stations, the cyclonic area had reached here and a moderate breeze from N.N.E. was felt. The upper clouds came moving fast from E.N.E. On the 10th at 5.45 a. directions to fire the Typhoon Gun one round were given, a strong northerly gale being expected, at 10.15 ́a. the following notice was telegraphed to the Treaty Ports:-"Typhoon approaching Hongkong from the East." and at 6.28 p. directions to fire the Typhoon Gun two rounds were given, it being then curtain, that the velocity of the wind would reach 80 miles an hour.
