The River Poem by Richard Watson Gilder

I know thou art not that brown mountain-side,
Nor the pale mist that lies along the hills
And with white joy the deepening valley fills;
Nor yet the solemn river moving wide
Into that valley, where the hills abide
But whence those morning clouds on noiseless wheels
Shall lingering lift and, as the moonlight steals
From out the heavens, so into the heavens shall glide.
I know thou art not this gray rock that looms
Above the water, fringed with scarlet vine;
Nor flame of burning meadow; nor the sedge
That sways and trembles at the river's edge.
But through all these, dear heart! to me there comes
Some melancholy, absent look of thine.
