Inscription at Walter McJones burial site located at Hacienda El Limón in Villalba, PR:
"If you can force your heart and nerve and sinew
To serve your turn long after they are gone,
And so hold on when there is nothing in you
Except the Will which says to them: “Hold on”;
Yours is the Earth and everything that’s in it,
And—which is more—you’ll be a Man, my son!"
Excerpt from poem by Rudyard Kipling, 1865 - 1936
