I solely crave that one of all the beams
Which do Sun's work in darkness, at my will
Should operate—myself for once have skill
To realize the energy which streams
Flooding the universe. Above, around,

Simply of service, when the world grows dark,
To half-surmise—were Sun's use understood,
I might demonstrate him supplying food,
Warmth, life, no less the while? To grant one spark
