28.91. Blowing hard about force 9, in squalls. 

 Tide falling fast, the wind since it 

 shifted to the southward forcing it 

 out of the river against the flood, 

 as fast as the wind before had forced 

 it up against the ebb. 



28.99. Blows harder in the puffs, but moder- 

 ates more than it did (and for a 

 longer period) between them, look- 

 ing wild ; water falling. 



29.04. Gusts less frequent with long lulls 

 between them, when it is almost 

 calm, sun just now shining out, 

 weather gloomy and murky ; scud 

 flying rapidly from S. S. W. 



Blowing fresh in puffs. 



Blowing moderately fresh, but the same 

 dark murky and almost impervious 

 clouds, lighted here and there a little 

 by the sun behind them, raining fast, 

 becoming calm between the puffs. 



Blowing fresh ; about 5 force ; cloudy 

 with rain. 



Moderating to 4 force, with steady 

 rain. 



Dark and gloomy with fresh gusts and 

 very heavy rain. 



Long intervals of little wind between 

 the squalls, but they appear to in- 

 crease in strength to 7 ; wind backed 

 to south, looking very dirty with rain. 



Blowing hard (still) at times. 

 Blowing hard at times. 



High water at Shanghae on 20th, 6.30 p. m. 



Ditto ditto at Woosung ditto 4.51 ditto. 



During the swell of the tide, at the usual time of low-water, the tide was at 

 least 20 feet above low-water mark. 



From all I can learn, the mean of the lowest range of the whole of the mer- 

 chant Ships' Barometers (at Woosung and this place) was 28.63, the lowest 

 I hear of was 28.30 on board ship, and 28.10 on shore, and the Sympiesome- 

 ter on board ship 27.55. Our's stood more than one tenth higher than the 

 mean, but it has always been taken care of, and has during 2| years' service, (in 

 passages from England toBahia, thence to Cape of Good Hope, and Mauritius, 

 from thence to Hobart Town, and New Zealand and China,) never failed to give 

 us timely warning in every respect, and we consider it a good one.
