Valuable Minerals

Famous quotes containing the word valuable:

“All schools, all colleges, have two great functions; to confer, and to conceal, valuable knowledge. The theological knowledge which they conceal cannot justly be regarded as less valuable than that which they reveal. That is, when a man is buying a basket of strawberries it can profit him to know that the bottom half of it is rotten.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
