Famous quotes containing the words magic and/or number:
“But these young scholars, who invade our hills,
Bold as the engineer who fells the wood,
And travelling often in the cut he makes,
Love not the flower they pluck, and know it not
And all their botany is Latin names.
The old men studied magic in the flowers.”
—Ralph Waldo Emerson (1803–1882)
“States strong enough to do good are but few.
Their number would seem limited to three.”
—Robert Frost (1874–1963)
