Stephen Crane

The wayfarer, 
Perceiving the pathway to truth, 
Was struck with astonishment. 
It was thickly grown with weeds. 
“Ha,” he said, 
“I see that none has passed here 
In a long time.”
Later he saw that each weed 
Was a singular knife. 
“Well,” he mumbled at last, 
“Doubtless there are other roads.”

Stephen Crane, from War Is Kind and Other Lines (1899).
