Can't

How history repeats itself
You'll say when you remember Grant,
Who, in his boyhood days, once sought
Throughout the lexicon for "can't."

He could not find the word that day,
The earnest boy whose name was Grant;
He never found it through long years,
With all their power to disenchant.

No hostile host could give him pause;
Rivers and mountains could not daunt;
He never found that hindering word--
The steadfast man whose name was Grant.
