"There's a ship on the sea
And it's sailing to-night, sailing to-night,—
And father's aboard, and the moon is all bright.
Dear moon, he'll be sailing for many a night—
Sailing from mother and me.
O follow the ship with your silvery light,
As father sails over the sea."

Ship, sky and sea in the soft grays of night!

Which is darker, the sky or the sea?

Look at the light in the sky where it seems to meet the sea.

The ship looks darkest gray.

We see it against the lighter grays.

Paint a "ship on the sea, sailing to-night."
