And said, Hitherto shalt thou corns, but no further. The law is not quite absolute. Wherever the sea washes a coast-line, there is a continual erosive action, whereby the land is, little by little, eaten away, and the line of the coast thrust back.
But the action is so slow that millennia pass without any considerable effect being produced, and encroachments in some places are generally counterbalanced by retrenchment in others, so that the general contour of laud and water, with the proportion of the one to the other, remain probably very much the same at the present day as when the earth first became the habitation of man.
And here shall thy proud waves be stayed. The waves of the sea "rage horribly," and every now and then topple down a rock or undermine a cliff, and seem proud of their achievements; but how little do they effect, even in thousands of years!
The little islet of Psyttaleia still blocks the eastern end of the straits of Salamis. The Pharos island lies off the westernmost mouth of the Nile. Even the low, fiat Aradus, on the Syrian coast, has not been swept away.
Everywhere the waves are practically "stayed," and all the menaces of the sea against the land come to nought.
