10 A slender stream became a naked sprite,
Flashed around curious bends, and winked at me
Beyond the turns, alert and mischievous.
A saffron moon, dangling among the trees,
Seemed like a toy balloon caught in the boughs,
Flung there in sport by some too-mirthful breeze..
And as it hung there, vivid and unreal,
The whole world's lethargy was brushed away;
The night kept tugging at my torpid mood
And tore it into shreds. A warm air blew
My wintry slothfulness beyond the stars;
And over all indifference there streamed
A myriad urges in one rushing wave...
