Toward noon we stopped by the wayside, near the Upper Village of the New Gloucester Shakers, to rest and feed the horses, and to give the hogs water.

About one o'clock we went on down the hill to Sabbath Day Pond and into the woods beyond it.

The loads were heavy and the horses were plodding on slowly, when, just round a turn of the road in the woods ahead, we heard a deep, awful sound, like nothing that had ever come to our ears before.

For an instant I thought it was thunder, it rumbled so portentously: _Hough--hough--hough--hough-er-er-er-er-hhh!_ It reverberated through the woods till it seemed to me that the earth actually trembled.
Willis's horses stopped short.

Willis himself rose to his feet, and it seemed to me his cap rose up on his head.
