A learned man came to me once. 

A learned man came to me once. 
He said, “I know the way, — come.” 
And I was overjoyed at this. 
Together we hastened. 
Soon, too soon, were we 
Where my eyes were useless, 
And I knew not the ways of my feet. 
I clung to the hand of my friend; 
But at last he cried, “I am lost.”
