Once I saw mountains angry,  
And ranged in battle-front.  
Against them stood a little man;  
Aye, he was no bigger than my finger.  
I laughed, and spoke to one near me,  
"Will he prevail?"  
"Surely," replied this other;  
"His grandfathers beat them many times."  
Then did I see much virtue in grandfathers --  
At least, for the little man  
Who stood against the mountains.
Stephen Crane
