Named For Two Fathoms Poem by Ima Ryma

Samuel Langhorne Clemens did do
Some piloting of a steamboat
Up and down the Mississipp, true!
So as a writer he did note
He should come up with a new name
That rolled better off of the tongue,
Give him a legacy of fame
Among the reading old and young.
Remembering his river days,
That two fathoms or twelve feet be
Safe depth for sail through river ways,
Seeing mark two meant boat safety.

Famous status he did attain,
Writing under the name, Mark Twain.
