It seemed impossible that human beings could live in this
rock-wilderness. If so, they must be to other men what the lean, hardy
cattle of the hills are to the corn-fed stabled beeves of the States.

Over the shoulder of a hill came a whistling which might have been
attributed to the wind, had not this day been deathly calm. It was fit
music for such a scene, for it seemed neither of heaven nor earth,
but the soul of the great god Pan come back to earth to charm those

be replaced with a stare of interest. It was impossible to tell why
