Famous quotes containing the words electric and/or power:
“That’s the down-town frieze,
Principally the church steeple,
A black line beside a white line;
And the stack of the electric plant,
A black line drawn on flat air.”
—Wallace Stevens (1879–1955)
“an age of unscrupulous and shameless book-making, it is a duty to give notice of the rubbish that cumbers the ground. There is no credit, no real power required for this task. It is the work of an intellectual scavenger, and far from being specially honourable.”
—Richard Holt Hutton (1826–1897)
