No sooner was the scorpion settled on the tortoise's broad back, than the tortoise crawled into the water and began to swim. Halfway across he was startled by a strange rapping on his back, which made him ask the scorpion what he was doing.
"Doing?" answered the scorpion. "I am whetting my sting to see if it is possible to pierce your hard shell."
"Ungrateful friend," responded the tortoise, "it is well that I have it in my power both to save myself and to punish you as you deserve." And straightway he sank his back below the surface and shook off the scorpion into the water.
