Early Days in the Bureau (continued)The lower two floors of the Divisional Office building were occupied by the meteorological staff. An external staircase connected the lower floors to the roof which housed some meteorological instruments including anemometer masts. On the lower floor were a number of recording devices with rotating drums driven by clockwork. I have a vague memory of one recording drum being rotated by a weight suspended on a chain. These instruments recorded wind direction and speed and atmospheric pressure. More precise readings of pressure, temperature, rain and wind were made and recorded during the day but values at other hours were abstracted from the charts of the recording devices in the office and the instrument enclosure.
A novel device was the teleprinter on which coded messages were sent to and received from other Bureau offices and the central telegraph office of the Postmaster-General's (PMG) Department. The lower floor also contained tables used for plotting surface observations on synoptic maps, preparing rain maps and tabulations of rainfall and temperature observations throughout NSW and other States. Members of the press and others seeking information made their requests at a counter near the front door.
In the grounds of the Divisional Office was an instrument enclosure containing a Stevenson screen, ground, underground and solar thermometers and rain gauges, including a recording pluviograph. The Stevenson screen contained dry and wet-bulb and maximum and minimum thermometers and clockwork-driven thermographs and hygrographs.
Observations were received from Bureau stations in five-figure code groups or from cooperative observers in word code. Many of the cooperative observers were post office staff or private individuals including farmers. The word code consisted of words of various length.
