Joe was most definitely not going anywhere with an unconscious comrade, so he was content to wait by the fire, which he now noticed had started to dwindle. Reluctantly, he searched around the camp site for anything to keep it going. It was while he was gathering wood, that an idea struck him.  On Valka, his home planet, there was a species of tree that had needles much like the pine trees of Earth.  Burning those needles would produce a dark smoke that would be visible from far away.  Of course, there was no telling if such a tree existed here, since he wasn't even sure what planet he was currently on.  In an attempt at wry humor, he thought to himself,<em>man, I hope I earn some frequent flyer miles from this.</em>He picked up a small branch with what looked to be similar characteristics and hoped that it wasn't posionous or highly flammable.  After putting some more firewood onto the fire, he gingerly placed the branch onto the flames.<em>here goes. I hope this works...</em>If his plan worked, the others would hopefully see the smoke rising from his camp, since he was at the top of a waterfall. Otherwise, it might just attract trouble, something he really didn't want at the moment. As he sat down next to the fire again, a frown crossed his boyish features. The amount of unknown factors about this place irked him. He preffered to go into situations wielding as much knowledge as possible, that way he could formulate a strong strategy. Now he was forced to make decisions on mere guesswork.
