Famous quotes containing the words national and/or trail:
“There is no national science just as there is no national multiplication table; anything that is national is not scientific.”

and wash them with your salt,
you will curl between sand-hills
you will thunder along the cliff
break retreat get fresh strength
gather and pour weight upon the beach.”
