Famous quotes containing the words hazardous and/or materials:
“Falling in love with a United States Senator is a splendid ordeal. One is nestled snugly into the bosom of power but also placed squarely in the hazardous path of exposure.”

“What is most interesting and valuable in it, however, is not the materials for the history of Pontiac, or Braddock, or the Northwest, which it furnishes; not the annals of the country, but the natural facts, or perennials, which are ever without date. When out of history the truth shall be extracted, it will have shed its dates like withered leaves.”
—Henry David Thoreau (1817–1862)
