 Within five months Kitching, with the aid of his younger brothers, had assembled a collection of more than 200 fossil specimens as research material for the Bernard Price Institute, mostly skulls of therapsid species.Price was so thrilled with the success of the institute's first field trip that he doubled his funding propositions for the BPI.This allowed the institute to extend its field collecting activities to include Sterkfontein in the north and also the Makapansgat caves at what was then known as the Northern Transvaal (now Limpopo Province) of South Africa.
