Nature’s first green is gold,
Her hardest hue to hold.
Her early leaf’s a flower;
But only so an hour.
Then leaf subsides to leaf.
So Eden sank to grief,
So dawn goes down to day.
Nothing gold can stay.

Yesterday I held your hand,
Reverently I pressed it,
And its gentle yieldingness
From my soul I blessed it.

But to-day I sit alone,
Sad and sore repining;
Must our gold forever know
Flames for the refining?

Yesterday I walked with you,
Could a day be sweeter?
Life was all a lyric song
Set to tricksy meter.

Ah, to-day is like a dirge,—
Place my arms around you,
Let me feel the same dear joy
As when first I found you.

Let me once retrace my steps,
From these roads unpleasant,
Let my heart and mind and soul
All ignore the present.

Yesterday the iron seared
And to-day means sorrow.
Pause, my soul, arise, arise,
Look where gleams the morrow.

Whose woods these are I think I know.
His house is in the village though;
He will not see me stopping here
To watch his woods fill up with snow.

My little horse must think it queer
To stop without a farmhouse near
Between the woods and frozen lake
The darkest evening of the year.

He gives his harness bells a shake
To ask if there is some mistake.
The only other sound's the sweep
Of easy wind and downy flake.

The woods are lovely, dark and deep.
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.

This veil
Of lavender and dawn
Floats off
Invisible, 
And this of purple noon
Unwinds in wisdom,
Twitters, undulates,
Dips, darts, 
And this of night
Circles around me singing
To the very edge and presence of the young moon—
And it brushes the tip
Like lips
Three times.

Light o’ the lodge, how I love thee,
Light o’ the lodge, how I love thee,
         Mianza, my wild-wood fawn!
To wait and to watch for thy passing.
          On hill-top I linger at dawn.

Glimmer of morn, how I love thee, 
Glimmer of morn, how I love thee! 
      My flute to the ground now I fling,
      As you tread the steep trail to the spring,
For thy coming has silenced my song.

Shimmer of moon on the river,
Sheen of soft star on the lake!
     Moonlight and starlight are naught;
     Their gleam and their glow is ne’er fraught
With such love-light as falls from thine eyes.
