When we found him in the woods, he was a sorry sight-his clothes torn and his hands bleeding. Before we 　21 　him, we saw him 　22 　. He lay for a moment. Then he 　23 　to his feet, walked a few yards with difficulty and fell again. When we lifted him off the 　24　 , he tried to break away and ran like a wild animal.

If he 　37 　experience, it may lead him to 　38 　the move in a false 　39　 　to find the camp against all chances. He might walk in circles or in the wrong direction, which in the end 　40 　him out physically and mentally.
