PREFACE.
From the days of my boyhood I had been stirred with the desire to devote myself in some way to the exploration of Africa, and whenever I came across the narratives of travellers who had contributed anything towards the opening up of the dark continent, I only read them to find that they gave a more definite shape to my longings.
It was in 1872 that an opportunity was afforded me of gratifying my wish, and I then decided that South Africa should be the field of my researches. For seven years I applied myself to my undertaking with all the energy, and with the best resources that, as a solitary individual, I could command, and was enabled to make the three journeys which are described in the following pages.
On my third return to the Diamond-fields I was urged by my South African friends immediately to publish an account of my travels; my time, however, was so engrossed by my medical practice that I had no leisure for the purpose, and contented myself with merely sending a few fragmentary articles to some of the South African newspapers.
