Mechanically I strode on, avoiding without conscious volition the shrubs and tussocks. As the moon ascended the shadows shortened and became less grotesque. Fancied resemblances to and suggestions of things outside my own experience, but of which my mind had formed concepts that had become familiar, switched thought on to other tracks; the pendulum swung from the subjective to the objective. Imagination built up the tiny, lithe, agile forms of that race we exterminated and whose barren territory we annexed, but neither occupied nor made use of. I could almost hear the sandalled, pattering feet of the aboriginal dwellers of these plains,--those kings of the waste whose sceptre was the poisoned dart. The Bushmen were in many respects a wonderful people. They obeyed no chief; they had no political organisation whatsoever; each family governed itself independently. Yet they had their fixed customs,--their general traditional code of proprieties. They had knowledge of the properties of plants which no others possessed; they had a highly-developed dramatic art. As limners they excelled, and a keen sense of humour is evinced in many of their paintings. Not alone was this sense of humour keen, but it must have been very much akin to our own. How many hot human hearts have searched for a clue to the nature of that Power which energises as much through evil as through good,--which could foster the development of a numerous people under painful and inexorable laws until it harmonised with its rigorous environment,--that could implant in its units the capacity for love, heroism and faithfulness-- and then ordain or sanction its obliteration,--an obliteration so absolute that, with the exception of one aged and senile pair, and a few delineations on sheltered rocks, of animals that shared its doom, this people has not left a trace behind. Literally, not a trace; hardly so much evidence that it ever existed as afforded in the case of an extinct sub-species of diatoms, the imprint of whose forms may be found on the fractured face of a chalk-cliff. Musing thus, I suddenly became aware that day was at hand, for the pallid moonlight grew paler and the thrill of approaching dawn pulsated through the firmament. If all my trouble were not to be thrown away, I should at once select a spot suitable for my ambush. But first I had to look out for a certain shallow-rooted shrub of globular form which grew in patches here and there throughout the desert. A few such shrubs had to be pulled out of the ground and piled in the form of a low, circular fence enclosing a space about six feet in diameter. This is the "scherm" or screen so often used by those who hunt in the desert. Within it the hunter lies prone, fully concealed from any approaching quarry.
