The Crow and the Pitcher
A crow, ready to die with thirst, flew with joy to a pitcher, which he saw at a distance. But when he came up to it, he found the water so low that with all his stooping and straining he was unable to reach it. So he tried to break the pitcher, then to overturn it, but his strength was not sufficient to do either. At last, seeing some small pebbles at hand, he dropped a great many of them, one by one, into the pitcher, and so raised the water to the brim and quenched his thirst.
