OVER the wintry threshold
Who comes with joy to-day,
So frail, yet so enduring,
To triumph o'er dismay?
Ah, quick her tears are springing,
And quickly they are dried,
For sorrow walks before her,
But gladness walks beside.
She comes with gusts of laughter,—
The music as of rills;
With tenderness-and sweetness, —
The wisdom of the hills.
Her hands are strong to comfort,
Her heart is quick to heed.
She knows the signs of sadness,
She knows the voice of need.
There is no living creature,
However poor or small,
But she will know its trouble,
And hasten to its call.
Oh, well they fare forever,
By mighty dreams possessed,
Whose hearts have lain a moment
On that eternal breast.

Bliss William Carman
