What have we here? So very round and smooth and sharp. To me tis might clear This wonder of an Elephant is very like a spear!” The 3 rd approached the animal and happening to take The squirming trunk within his hands, Thus boldly up and spake: “I see,” quoth he, “the Elephant is very like a snake.” The 4 th reached out an eager hand And felt about the knee. “What most this wondrous beast is like Is mighty plain,” quoth he; “Tis clear enough the Elephant is very like a tree.” The 5 th, who chanced to touch the ear said “Even the blindest man can tell what this resembles most; Because of its great span, This marvel of an Elephant is very like a fan!” The 6 th no sooner had begun about the beast to grope, Then seizing on the swinging tail that fell within his scope, “I see,” quoth he, “the Elephant is very like a rope.” And so these men of Indostan Disputed loud and long. Each in his own opinion Exceeding stiff and strong, Though each was partly in the right, And all were in the wrong.
