On the 25th August the sea observations show that winds had a tendency to circulate around the position 16°, 115° and the barometric observations also indicate that pressure was slightly low in this part of the China Sea. On the 26th pressure had decreased in Hainan and along the S coast of China where winds were moderate but increasing from E and NE accompanied by showery and squally weather. The noon observations made at sea show that pressure had also decreased to the SE of Hainan during the preceding 24 hours and indicate the existence of a cyclonic depression (XI) of slight intensity with its centre in about 18°, 112°. At a distance of about 100 miles from this position winds were no stronger than moderate or fresh breezes at this time. but during the evening the steamships Hupeh, Glenesk and Sishan steering for Hongkong, in rear of the centre, had the wind increasing from the SE with rising barometer, the latter vessel experiencing a strong gale with rain- squalls and a high sea at midnight. The S.S. Machew was to the WSW of the centre in the morning and also steering towards Hongkong. During the evening the fresh NW breeze that had been experienced during the morning died away and gave place to a gentle SE breeze. At 2 a. of the 27th the barometer attained its lowest point, 29.55, and at 3 a. the wind rose to a fresh gale from ESE accompanied by heavy rainsqualls. It appears, therefore, that this vessel passed through the central area during the evening of the 26th and the observations show that the disturbance was only a shallow depression with moderate or slight gradients to the westward of and in the central area. In depressions of this class which form in the northern part of the China Sea and generally move towards the Gulf of Tongking strong winds are seldom developed on their western sides where the gradients are moderate owing to the low pressure usually prevailing in the Gulf of Tongking and neighbouring coasts during the summer. The disturbance was now moving to the WNW and it entered the East coast of Hainan during the morning of the 27th. At Hoiliow strong NE breezes veering to SE were experienced accompanied by wet squally weather, the barometer rising during the afternoon. On the S coast of Hainan, at Yulinkau, the I.M.C.C. Likin experienced fresh SSW breezes with rain during the morning increasing to a moderate gale at night with rising barometer. At noon on the 27th August the centre was situated in about 154, 109°, and it was about to pass from Hainan into the Gulf of Tongking. As pressure had increased very considerably in the neigh- bourhood of and to the southward of Hongkong, gradients were rather steep between Hongkong and Hainan and SE gales prevailed at sea between the two places. The S.S. Machew sustained great damage about her decks owing to the heavy sea which got up. The disturbance crossed the Gulf of Tongking between the 27th and 28th, and during the morning of the latter day the centre entered the coast a little to the South of Haiphong at which station a fresh NNE breeze prevailed during the morning veering to ESE and increasing to a gale with rising barometer during the afternoon.
The depression never attained any great intensity and the strongest winds reported were of force 9 only. Its average rate of progression between the 26th and 28th was nearly 8 miles per hour.
Although the information issued from the Observatory with regard to this depression was substantially correct it may be stated that no observations were received from Hoihow between August 20th and 30th. As the disturbance crossed Hainan and as it was at all times nearer to Hoihow than to Hongkong it is readily seen that such observations would have afforded valuable assistance had they come to hand.
September 5th, 4.27 p. "There appears to be a depression to the East of Luzon.”
September 6th, 11.9 a. "The barometer continues to fall at Bolinao. On S coast, barometer steady with fresh NE winds and fair weather."
