The maxim originates from the story that a bird called tittiva lived on the beach of a sea, one day the beach was washed away by a huge wave of the sea. The eggs which the bird lay in the nest were also washed away in consequence. Engaged at this the bird resolved to laddle off the sea and began to throw away the water with its beak and also with its wings, which it once dipped into the sea and then came up and shook them. Struck with wonder at the ?run determination of the bird the sea returned its eggs. It is used to denote that all sorts of difficulties, however unsurmountable they may seem to be, melt away before firm determination. Cf.Labour surmounts every difficulty.
