Poem from Charles Dickensen

We never now how high we are
till we are called to rise

And then if we are true to plan
our staures reach the skies

The heroism we recite
would be a daily thing

Did not ourselves the CUBITS WARP
for fear to be a king

Ich suche die Bedeutung der ersten Zeile des letzten Verses.
