No More Learning

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 265
Of the clear flood, from things which there abide
In their true dwelling; now is crossed by gleam
Of his own image, by a sun-beam now,
And wavering motions sent he knows not whence,
          that make his task more sweet; 270
Such pleasant office have we long pursued
Incumbent o'er the surface of past time
With like success, nor often have appeared
Shapes fairer or less doubtfully discerned
Than these to which the Tale, indulgent Friend!
