Extract

If there is one branch of geology that was more strongly represented than another at the Fifteenth International Geological Congress in Pretoria, it is petrology. It is true that the petrologists did not present many papers, and that their official discussions were rather scamped, but it was on the excursions that they showed their real strength. I shall not soon forget the day when I conducted a party of fifty to Pilansberg. To see them jump from the buses at every stop; to hear fifty hammers ringing at once on my favourite nepheline rocks; to see the collecting bags swelling and the buses sinking lower and lower on their springs; few sights have ever given me keener pleasure. The Franspoort-Leeuwfontein excursion was also a purely petrological occasion, in which more than fifty took part; and then at the end of the Congress some thirty of us enjoyed ten days of concentrated petrology on the Bushveld excursion, under the inspiring leadership of A. L. Hall.
