 Aufhorities:

19 1 2 June to 1920. Meteorological Office, Department of 



Irrigation, Pretoria. 



Site: From 1873 to 1883, the observations were taken at the 

 Botanic Gardens, and from 1884 to 1912 May at 

 the Observatory, with an over-lapping period of 

 seven months in 1884 of fair agreement, so that the 

 two records may be regarded as a comparable series 

 of 39 years at a height of 262 ft. From 19 12 June 

 to 1920, the rain gage was at a height of 50 ft., and 

 no correction has been applied to these figures. 



Instrument: An 8-inch gage was in use at the Observatory with 

 the rim 3 ft. 6 in. above the ground.

All values have been corrected to a height of 3842 ft. by 



applying the following corrections:

 the period. The index error correction is unknown, 

 but presumed to be applied.

 April 1904, but the observations from this instru- 

 ment have been rejected as inaccurate.
