From "Woods in Winter" by Henry Wadsworth Longfellow
When winter winds are piercing chill,
And through the hawthorn blows the gale,
With solemn feet I tread the hill,
That overbrows the lonely vale.

O'er the bare upland, and away
Through the long reach of desert woods,
The embracing sunbeams chastely play,
And gladden these deep solitudes.

Where, twisted round the barren oak,
The summer vine in beauty clung,
And summer winds the stillness broke,
The crystal icicle is hung.
