AESOP'S FABLES, The Tortoise and the Birds

"A Tortoise desired to change its place of residence, so he asked an Eagle to carry him to his new home, promising her a rich reward for her trouble. The Eagle agreed and seizing the Tortoise by the shell with her talons soared aloft. On their way they met a Crow, who said to the Eagle: Tortoise is good eating. The shell is too hard, said the Eagle in reply. ‘The rocks will soon crack the shell, was the Crow’s answer; and the Eagle, taking the hint, let fall the Tortoise on a sharp rock, and the two birds made a hearty meal of the Tortoise. Never soar aloft on an enemy’s pinions." AESOP'S FABLES
