A week later, Tarzan builds a shelter and makes it his retreat, gathering anything interesting that he has found from the village wrecks, including his hunting knife. Here, Tarzan also discovers a long abandoned pickaxe under it. The next day He's practicing with his bow and arrows at the first gleam of dawn. At first he lost nearly every bolt he shot, but finally he learned to guide the little shafts with fair accuracy, and by the time a month has passed, he was no mean shot; but his proficiency had cost him nearly his entire supply of arrows.
