Extract from the Log of the Ship Ann, of London, Capt. Stevenson. 



Civil Time. 



On the 8th Oct. 1845 the Ann was in Lat. 19° 46' N'.; Long. 114° 36' 

 East; moderate and fine, wind N. Easterly. 



9th Oct. — a. m. light breezes increasing to strong breezes at noon, when cloudy 

 and a heavy head sea. Wind N. N. W. Lat. 19° 24' North ; Long. 115° 30' 

 E. ; 1 p. m. perceived a peculiar appearance of the atmosphere. The Barometers 

 as usual, 30.00, and 29.80 ; had sent down small sails, &c. in preparation 

 to beat to the eastward but not apprehending bad weather. Sunset increasing 

 wind ; appearance of atmosphere more settled and Barometer steady ; at lOh. 30. 

 Bars, fell two-tenths ; ship standing to the E. N. E. under snug sail at 8 p. m. but 

 gale increasing considerably reduced ship at midnight to storm sail. 



Wth Oct. — a. m. Barometers falling rapidly, 29.30 and 29. 50. At daylight 

 increasing to a Tyfoon. Split and cut away main topsail, being unable to 

 furl it. Ship under storm mizen. Noon Barometer 29.00 and 29.20 ; 1 p. m. 

 28.80 and 29.00. Under bare poles with a tarpaulin in the mizen rigging ; 4 

 p. m. Bar. 28.50 and 28.70 ; gusts of wind and confused sea — fearful ; 4.30 

 p. m. cut away quarter boats. At 5 p. m. Bar. 28.50 and 28.80, with an alarm- 

 ing appearance, ship lying with tarpaulins in mizen rigging with her head to the 

 Eastward and drifting fast to the Southward.* At 5.30 tremendous gusts with 

 perfect sheets of foam all round, the spray sweeping over the mast-heads. The 

 heavy seas that struck the ship and which we expected would make a clean sweep 

 of the upper deck fore and aft disappeared over our heads like a sheet of light- 

 ning from the fury of the wind. At 7 Bar. 28.00 and 28,20 ; heavy rain. About 

 8 p. m. Typhoon moderating, sea in a more confused state. Ship labouring 

 dreadfully; at 9 p. m. Tyfoon fell suddenly light, and veeredf to the S. East- 

 ward; head from S. W. to W. S. W. rolling awfully, but Bar. still inclined to 

 fall ; did not venture to make sail. At 10.30 wind increasing from the S. E. ; 

 at llh.20 every appearance of an approaching hurricane from the S. Eastward. 

 During the lapse of 50 minutes the Bars, fell 0.3, and were now at 27.70 and 

 27.80. Midnight, Tyfoon blowing with awful fury and the sea fearful in the 

 extreme, washing away every thing before it. Fore topmast, jibboom and head 

 of the foremast gone, which was not discovered till daylight. 



* The direction of the wind is not given, but from this it must have been 

 about N. N. E. 



f The Italics are mine ; it might almost be called a shift.
