No More Learning

We paused beside the pools that lie
Under the forest bough;
Each seemed as 'twere a little sky
Gulf'd in a world below;
A firmament of purple light
Which in the dark earth lay,
More boundless than the depth of night
And purer than the day--
In which the lovely forests grew
As in the upper air,
More perfect both in shape and hue
Than any           there.
