Henry David Thoreau on Walking

Here is a excerpt from Thoreau's well-known speech on walking. For the complete speech, click here.
I have met with but one or two persons in the course of my life who
understood the art of Walking, that is, of taking walks -- who had a
genius, so to speak, for sauntering, which word is beautifully
derived "from idle people who roved about the country, in the
Middle Ages, and asked charity, under pretense of going a la Sainte
Terre," to the Holy Land, till the children exclaimed, "There goes a
Sainte-Terrer," a Saunterer, a Holy-Lander. They who never go to
the Holy Land in their walks, as they pretend, are indeed mere
idlers and vagabonds; but they who do go there are saunterers in
the good sense, such as I mean. Some, however, would derive the
word from sans terre without land or a home, which, therefore, in
the good sense, will mean, having no particular home, but equally
at home everywhere. For this is the secret of successful sauntering.
He who sits still in a house all the time may be the greatest vagrant
of all; but the saunterer, in the good sense, is no more vagrant than
the meandering river, which is all the while sedulously seeking the
shortest course to the sea.
