To come down to my own experience, my companion and I, for I sometimes have a companion, take pleasures in fancying ourselves knights of a new, or rather an old, order---not Equestrians or Chevaliers, not Ritters or Riders, but Walkers, a still more ancient and honorable class, I trust. The chivalric and heroic spirit which once belonged to the Rider seems now to reside in, or perchance to have subsided into, the Walker---not the Knight, but Walker Errant. He is a sort of fourth estate, outside of Church and State, and People... No wealth can buy the requisite leisure, freedom, and independence which are the capital in this profession. It comes only by the grace of God. It requires a direct dispensation from Heaven to become a walker. You must be born into the family of Walkers. Ambulator nascitur, non fit."
