We forgot this one :

O moonlight deep and tender,
A year and more agone,
Your mist of golden splendor
Round my betrothal shone!
O elm-leaves dark and dewy,
The very same ye seem,
The low wind trembles through ye,
Ye murmur in my dream!
O river, dim with distance,
Flow thus forever by,
A part of my existence
Within your heart doth lie!
O stars, ye saw our meeting,
Two beings and one soul,
Two hearts so madly beating
To mingle and be whole!
- James Russell Lowell
