I cannot sleep—my nights glide on
In one unbroken thought of thee;
And when the gloomy shades are gone,
I start the dawning light to see.
And as I watch the rising morn
Gain slowly o'er the yielding sky,
And mark another day new born,
That glows so brightly—yet must die—
I think how all the hopes we cherish
As transient, though as bright, will be;
And frailest of the hopes that perish
Were mine, that told of love and thee!
