His own supply of energy and skill!
As much of Shakespeare, Homer, Socrates,
As much of Wagner, Beethoven, and Bach,
As much of Franklin, Morse, and Edison,
As much of Watt, and Stephenson and Bell,
Of Euclid, Aristotle, Angelo,
Columbus, Raleigh, and George Washington,
Of all the learning of our patient years,
Of all the peace and smoothness we have won,
Of all the heaped up sciences and arts,
