As one who hangs down-bending from the side
Of a slow-moving boat, upon the breast
Of a still water, solacing himself
With such discoveries as his eye can make
Beneath him in the bottom of the deep,
Sees many beauteous sights -- weeds, fishes, flowers,
Grots, pebbles, roots of trees, and fancies more,
Yet often is perplexed and cannot part
The shadow from the substance, rocks and sky,
Mountains and clouds, reflected in the depth
Of the clear flood, from things which there abide
In their true dwelling; now is crossed by gleam
Of his own image, by a sunbeam now,
And wavering motions sent he knows not whence,
Impediment that make his task more sweet;
Such pleasant office have I long pursued
Incumbent o'er the surface of past time.
