Memories of a Summer Friend

In summer-noon flushes
When all the wood hushes,
Blue dragon-flies knitting
To and fro in the sun,
With sidelong jerk flitting
Sink down on the rushes.
And, motionless sitting,
Hear it bubble and run,
Hear its low inward singing
With level wings swinging
On green tasselled rushes,
To dream in the sun.

(Lowell, "The Fountain of Youth")
