The dusk is down on the river meadows,
The moon is climbing above the fir,
The lane is crowded with creeping shadows,
The gorse is only a distant blur;
The last of the light is almost gone,
But hark! They're running!
They're running on !
The count of the years is steadily growing;
The Old give way to the eager Young;
Far on the hill is the horn still blowing,
Far on the steep are the hounds still strung.
Good men follow the good men gone;
And hark! They're running!
They're running on!

William Henry Ogilvie
