Piercing the waves along its track

With the slant javelins of rain.

And when west-wind and sunshine warm

Chased out to sea its wrecks of storm,

They saw the prismy hues in thin spray showers

Where the green buds of waves burst into white froth-flowers!

Even better is the description of the breakers seen by twilight:—

... trampling up the sloping sand,

In lines outreaching far and wide,

The white-maned billows swept to land,
