Sail on Three Bells forever

In grateful memory sail!

Ring on Three Bells of rescue

Above the wave and gale!

As thine in night and tempest

I hear the Master’s cry

And tossing through the darkness

The lights of God draw nigh.—Whittier.

It may be generally stated that a Semi-colon is used in a complex sentence when a comma would not be a sufficient division.
