Protected Species
     Protected Species is a short story about the arrival of a sort of colonial administrator on the planet  Orang on which people are establishing a colony. The human race has just learned how to travel to other stars and is just starting to branch out.
    On this particular planet they find that (1) they are not the only life and (2) they aren't the first intelligent people to have lived there. There are forests (my kinda place) containing animals, including a bi-pedal race which is presumed to be at best only semi-intelligent and which the human colony workers hunt for sport. There are also ancient ruins;  half buried buildings with doors, windows, roofs, walls...many of which appear to have been destroyed in a battle.
    The lead guy becomes convinced that the Orangs, as they are called, are the degenerated descendants, now just animals, of the survivors of an ancient interplanetary war in which their civilization was destroyed (hence the ruins). He has them declared a protected species and he tries to make contact with them. He finally succeeds and finds out how wrong he is . . . . .

This is really my kind of story: it's short, doesn't waste my time, and the ending just comes up and slaps you upside the head (unless you've been forwarned...). If you want to know how it ends, look up the story...or if that's too hard, send me an e-mail and I may tell you....
