O Captain! my Captain! rise up and hear the bells!

Rise up! for you the flag is flung, for you the bugle trills:

For you bouquets and ribboned wreaths; for you the shores a-crowding:

For you they call, the swaying mass, their eager faces turning.


O Captain! dear father!

This arm I push beneath you.

It is some dream that on the deck

You've fallen cold and dead!

(from "Oh Captain! My Captain" by Walt Whitman)
