yup these are maybe #20 bows, the Bushmen are a small people, light in stature- an economical frame for their harsh environment. easier to feed and water a small frame.
their bows are for just puncturing the skin and delivering the poison, sometimes thir quarry can go for days, consequently those bushmen have become phenomenal trackers. have seen them do phenomenal things.
in the military they were used as trackers- a seat would be bolted to the fender of a landrover- and as fast as you can drive in the bush, they can follow an insurgents trail.
seen them follow an animal across massive "dwala's" huge acreages of flat rock, by bending down and blowing and seeing the lichin dust blow up that was dislodged.
they will follow a specific animal out of a herd of animals- waiting for the poisoned animal to break away from the herd.
hawkdancer, you are correct, they were the first peoples in southern africa,they were the first people the europeans met on the beaches. in fact, they were being pushed south by the advancing black tribes- coming down the lush east coast ( the west coast is very arid and desertified).
then the europeans were moving up north from their landfall in the Cape of Good Hope, the whites and the blacks met kinda halfway in what is called south africa today- at a place called "the great fish river", the bushmen were caught in the middle- and not loved by either group of people the black settlers saw them as a threat, the white settlers were having their cattle "stolen". they ended up being squished out sideways towards the west, and into the inhospitable desert areas, first the karoo and then ultimately the Kalahari.
In fact, i have always maintained that if anybody had title to south africa it would be the bushmen, and not the Black tribes or the white arrivals.
ironically they are the least concerned about land ownership or possession.
And yes, they have done a lot better than the other people groups, they find water in a massive sand desert, they hunt, they feast and the sleep- what an admirable people.
