On General Smuts’ farm Doornkloof is a magnificent avenue of plane trees; they were planted by Ouma Smuts’ brother, Jan Krige and the General’s son-in-law, Colonel Weyers, in 1917 and 1918. Colonel Weyers still farms on Doorknloof were there is a large herd of Blesbuck. Buck from this herd were supplied by Colonel Weyers in 1938 to the Pretoria Municipality for the van Riebeeck Nature Reserve at Rietvlei, where there is now a large herd and from these two herds many other herds throughout the Highveld have been propagated and now flourish.
