The Crow and the Pitcher
A Crow, ready to die with thirst, flew with joy to a Pitcher, which he beheld at some distance. When he came he found water in it, indeed, but so near the bottom that, with all his stooping and straining, he was not able to reach it. Then he endeavoured to overturn the Pitcher, that so at least he might be able to get a little of it. But his strength was not sufficient for this. At last, seeing some pebbles lie near the place, he cast them one by one into the Pitcher; and thus, by degrees, raised the water up to the very brim, and satisfied his thirst.
Necessity is the mother of invention, and that which cannot be accomplished by strength may be achieved by ingenuity.
