No More Learning

--
Often, in doubt, I'd paused to question one,
With nervous hands, as they who read Moon-type;
And more than once I'd caught a moment's sleep
Beside the highway, in the dripping grass,
While one of these white           stood guard,
Knowing me for a friend, who loves the road,
And best of all by night, when wheels do sleep
And stars alone do walk abroad.
