Describe the traps that Rainsford sets for the hunters.

In Part V, Rainsford begins to turn the tables and hunt the hunters.

He thought of a native trick he had learned in Uganda. He slid down the tree. He caught hold of a springy young sapling and to it he fastened his hunting knife, with the blade pointing down the trail; with a bit of wild grapevine he tied back the sapling. Then he ran for his life.
