All day the storm had been gathering behind Chimney Mountain and peering around the edges of that giant with a scowling brow, now and again; and all day there had been strainings of the wind and sounds of dim confusion in the upper air, but not until the evening did the storm break. A broad, yellow-cheeked moon was sailing up the eastern sky when ten thousand wild horses of darkness rushed out from behind Mount Chimney and covered the sky with darkness. Dashes and scatterings of rain and hail began to clang on the tin roofs in the valley, and the wind kept up a continual insane whining, now and then leaping against window or door and shaking them in an impatient frenzy.
