disorganisation of the work in the harbour, consequent upon the display of typhoon signals, is not easy to estimate. Probably amounts to many thousands of dollars a day, however.
VI. METEOROLOGICAL OBSERVATIONS FROM SHIPS, TREATY PORTS, &C.
Logs received. In addition to meteorological registers kept at about 40 stations in China, meteorological logs were received from 81 ships operating in the Far East. These logs, representing 2,587 days' observations, have been utilised for verifying typhoon tracks. The corresponding figures for the year 1918 were 34 and 2,223.
Pilot Charts. No progress has been made with the construction of Pilot Charts as the Chief Assistant was largely occupied with re-organising the Time Service in the latter part of the year, and the First Assistant, who returned from Active Service on August 12th, was occupied in re-measuring sunshine records and comparing magnetic instruments with the Chief Assistant.
Comparison of Barometers. During the year about 250 comparisons of ships' barometers have been made by means of observations taken when in harbour, and several direct comparisons of barometers for shipmasters and various persons in the Colony have been made at the Observatory.
VII. MAGNETIC OBSERVATIONS.
The mean values of the magnetic elements for the years 1918 and 1919 were as follows:
1918 1919 Declination (west) 0° 17' 57" Dip (north) 30° 48' 19" 30° 47' 30" Horizontal Force (C. G. S. unit) 0.37164 0.37171 Vertical Force (C. G. S. unit) 0.22159 0.22151 Total Force (C. G. S. unit) 0.43269 0.43270The old magnetic hut is about to be demolished and the site used for quarters for the European Assistants.
In order to avoid a break in the series of magnetic observations, comparisons for horizontal force and declination are being made with Elliott No. 55 in the old hut and Elliott No. 83 in the new hut (constructed last year). Also for dip with Dover No. 71 in the old and new huts.
VIII. TIME SERVICES.
Time Ball. The Time Ball on the Signal Hill, Kowloon, is dropped daily at 13h Hongkong Standard Time (5 a.m. of Greenwich Time). The ball is also dropped at any other hour in case of necessity. No applications for a supplementary signal were made in 1919.
