VI. MAGNETIC OBSERVATIONS.
15. The magnetic station at Au Tau has been kept in action throughout the year, and the results of the observations are now in the press.
VII. TIME SERVICE.
16. Clocks Cottingham and Mercer 507 (Sidereal) and Leroy 1350 were in use throughout the year. The necessary astronomical observations for the determination of the error of the former were obtained each evening (weather permitting) by the local staff. Observations of the radio time signals emitted by Nauen at 8h. a.m. have been made daily whenever possible during the year, and utilised for clock regulations.
17. Time Signals were given throughout the year by radio from 9.55 to 10 a.m. each morning and 8.55 to 9 p.m. each evening. Dots of about 0.1 sec. duration were transmitted at each second except for periods marking the minutes and half minutes. The evening programme was duplicated by 3 white lights (vertical) on the radio mast, the lights being extinguished each second in accordance with the radio programme.
Hourly signals were sent to the General Post Office, Radio Studio, Railway, the associated Telegraph Companies and the Telephone Co.
The errors of the time signals have been published monthly in the Government Gazette.
IX. MISCELLANEOUS.
18. Seismographs. The seismographs have been kept in good order throughout the year. 353 earthquakes were recorded, compared with 356 in 1933. The seismograms have been forwarded to the International Seismological Committee, Oxford.
19. Upper Air Research. Observations of 400 pilot balloons were made during the year. Details of the flights will be included in Meteorological Results for 1934.
20. Lithography. Lithographic work for other departments was undertaken as follows:
For Dept. Medical and Sanitary Services.
15,500 Charts
1,120 Maps.
Colonial Secretariat
120 Forms
Electrical Dept.
100 Forms
Harbour Dept.
